Shen Shuli originally put this barren mountain into the warehouse so that it would be convenient to use it to fill the pit directly when the time comes.

But now.

She unexpectedly came across an aluminum mine, so she would have to use it to upgrade her space!

The space is about to be upgraded to level ten.

Shen Shuli really wanted to know.

Is level ten the upper limit of space?

Anyway, this mountain is very big.

After upgrading the space, you can still store a lot of aluminum ore, which will definitely not be wasted.

Mu Wanjun, Xiao Yuxuan and Xie Chengyuan didn't expect this either.

Aluminum ore was discovered here!

...

...

Xie Chengyuan didn't know why Mu Wanjun and Xiao Yuxuan reacted so strongly.

In his opinion, he could not imagine what use aluminum ore had.

In this era.

No one had yet discovered aluminum ore or used aluminum as a metallic material.

So Xie Chengyuan had no idea what aluminum ore was or what it could be used for.

He looked at Mu Wanjun and Xiao Yuxuan in confusion.

The longer he interacted with them, the more he felt an inexplicable sense of disharmony from them.

It was as if they were from the same world and everyone else could understand what they said immediately.

But he was confused, like a newbie who knew nothing.

Especially Mu Wanjun and Xiao Yuxuan.

They were obviously people Xie Chengyuan already knew.

I have a relatively good understanding of their personalities.

But people of such noble status as them were actually the first group to get so close to the Su family!

Mu Wanjun and Xiao Yuxuan knew Su Yunhai's secret at some point!

According to what he knew.

Mu Wanjun and Shen Shuli have known each other for a long time.

But they only became close friends after the Su family fled to the capital.

And King Xuan, Xiao Yuxuan.

The Su family and King Xuan met in Yucheng!

Among them, he has the shortest acquaintance with the Su family!

But why would the Su family reveal the secret to King Xuan so easily?

Prince Xuan is a member of the royal family!

And he is a cousin of the current emperor Xiao Yuqi!

The Su family actually trusts Xiao Yuxuan so much!

Why do Su Yunhai and Shen Shuli trust them so much?

And I am the last person to know?

There must be some other unknown secrets here that he doesn't know about!

These thoughts flashed quickly through Xie Chengyuan's mind at this moment.

But he couldn't find any reasonable reason to explain this strange phenomenon.

For example, now.

Aluminum ore had never existed in the world he lived in.

But why did Mu Wanjun and Xiao Yuxuan act as if they knew a lot when they heard Shen Shuli talk about it?

"Prince Xuan, Princess, what exactly is this aluminum ore?" Xie Chengyuan couldn't help but ask.

Xiao Yuxuan immediately explained to Xie Chengyuan.

"Aluminum is a metal ore that is more precious than iron ore and much lighter than iron."

"For example, our helicopter needs to be made of aluminum. If we use aluminum to make a carriage, it will not only be lighter than a wooden one, but also stronger."

"It can also be used to make kitchen utensils such as aluminum pots and aluminum spoons, which are much lighter than iron pots of the same size."

"But the production process of aluminum is more complicated. Without core technology, it is impossible to refine aluminum ore..."

Having said this, Xiao Yuxuan realized that he had said too much and had spoken inappropriately.

Because he almost forgot his identity!

In this era, metal minerals such as aluminum had not yet appeared and were not used in daily life.

He said so much in front of Xie Chengyuan, he would definitely be exposed!

He glanced at Xie Chengyuan secretly.

really.

Xie Chengyuan was looking at him with suspicion!

It’s over!

This kid noticed something was wrong!

Mu Wanjun also reacted, and was worried that Xie Chengyuan would get to the bottom of it, so she quickly stepped out to interrupt.

"You are such a fool. You can remember whatever strange things my godfather told you. You really have a good memory."

Upon hearing this, Xiao Yuxuan quickly took advantage of the situation and explained, "Of course, Uncle Su has a heavenly book granted by an immortal, and he knows everything about astronomy and geography. I like to chat with Uncle Su and listen to his stories when I have nothing to do."

After saying that, Xiao Yuxuan secretly observed Xie Chengyuan's expression.

Xie Chengyuan didn't expect it to be like this.

It turns out that they knew so much, all from what they heard from Uncle Su!

Uncle Su was enlightened by an immortal, who not only granted him an immortal weapon but also a heavenly book!

Seems reasonable?

"So that's how it is." Xie Chengyuan could only convince himself this way.

Otherwise he would not be able to find a reasonable reason to explain these things that were wrong.

See finally fooled through.

Xiao Yuxuan let go.

Anyway, he could pin the blame on Uncle Su for any unreasonable things, and then everything would make sense.

Anyway, the topic has been opened.

Xiao Yuxuan also didn't want to hide everything from Xie Chengyuan, his good teammate.

He took the initiative to tell him a lot about the functions and uses of aluminum ore.

But overall.

This material is already a very mature and common material in the world where immortals live.

But if you want to use aluminum in their world, it is definitely a hundred times more difficult than making steel!

Xie Chengyuan was almost stunned.

He didn't expect that refining a small aluminum ore into the required metallic aluminum would be so complicated and tedious!

And this is something that current technology cannot do!

I feel so regretful!

Shen Shuli didn't know what Xie Chengyuan and the other two were discussing in the helicopter.

She is very motivated to move mountains.

This time it took a full ten days.

The space has only been upgraded to level ten!

But Shen Shuli was surprised to find out.

The space has undergone earth-shaking changes!

When the space reaches level nine, rewards are still given according to the previous rules.

But now that it has been upgraded to level ten, it has increased tenfold based on level nine!

The daily output of Lingquan water has increased from 20 liters to 200 liters!

The spiritual field was expanded from 100 acres to 1,000 acres!

The warehouse was originally only the size of ten football fields, which is about three thousand acres of space.

Now it has increased tenfold, reaching a total of 30,000 acres!

Even the 6,000-acre mountain range has now expanded to 60,000 acres!

There is also an additional aluminum mine of one thousand acres!

This change shocked Shen Shuli so much that she couldn't recover for a long time!

For Shen Shuli, this feeling was no less than the feeling of becoming rich overnight as if she had just obtained a space.

To upgrade the space.

Shen Shuli picked and chose among the nearby barren mountains, and collected almost all the mountains containing aluminum ore into her space, and only stopped after the space was upgraded.

The amount of waste soil collected in the warehouse is also sufficient.

Shen Shuli then returned to the helicopter, and the four of them returned directly to Qing Grant Mansion to fill the hole.

But Shen Shuli did not return to her previous Dashan appearance.

They just filled it up to make the ground flat and then stopped filling it up.

A lot of seeds were also sprinkled in the newly constructed area and the spiritual spring water was diluted to restore the ecology.

Finish these.

Four people sat in the helicopter and discussed the next mission.

Shen Shuli asked the three people: "Have you thought about it? Do you want to attack the people of the Northern Barbarian Army and drive them out?"

Mu Wanjun expressed her thoughts.

"I don't think it's necessary. Even if we can drive the northern barbarians away temporarily, we will have to leave sooner or later. They may come back soon and treat the people here more brutally."

Xiao Yuxuan agreed with Mu Wanjun's idea and said, "Ajun is right. Instead of thinking about how to drive the northern barbarians away, we should think about how to make the people here live better."

Xie Chengyuan knew that what the two said made sense, but he always felt aggrieved in his heart and didn't want to let the northern barbarians go just like that!

But he couldn't think of a better way, so he thought about it and said to Shen Shuli.

"How about we go to the northern barbarians' lair? There are grasslands over there. I heard that the northern barbarians are good at raising horses, cattle and sheep. We can't attack them, but we can choose to attack their supplies, right?"

"I think the Northern Barbarian Army doesn't have many troops stationed at their lair, so it's time to guard against a weak spot."

"If we can make a bigger noise, maybe we can lure these northern barbarian troops away, so that they can return to their base and temporarily abandon the city of Dayong."

Shen Shuli didn't expect Xie Chengyuan to be so smart that he could come up with such a clever idea to kill two birds with one stone!

"What a good plan! It's worthy of General Xie's attempt to hide this beautiful jade. Few people can match his brain!" Shen Shuli praised excitedly.

Xie Chengyuan didn't expect Shen Shuli to praise him so much, and there were two other pairs of sparkling eyes staring at him, which made his cheeks red.

"Hehe, the main reason why we can complete this plan is because you have a good magic weapon in your hand, otherwise it would not be possible to complete it at all." Xie Chengyuan instead put the credit on Shen Shuli.

Shen Shuli really liked the feeling of being complimented, and gave Xie Chengyuan a look that said, "You're a sensible boy."

Mu Wanjun said with emotion: "This is indeed a good idea, let's take action immediately."

Xiao Yuxuan also said sinisterly: "Okay, let's do it this way. We'd better take away all the supplies of the northern barbarians and see how they survive this extreme cold disaster!"

The weather that the northern barbarians hate the most is definitely the bitterly cold winter!

The cold winter means no food source and no rations for cattle and horses.

And this extreme cold disaster will last for a year!

This is definitely a huge blow to the barbarians living in the north!

This is also the reason why the northern barbarians are eager to occupy the border cities in the northern part of Dayong.

Because their living conditions are so bad, they have to rely on robbing to survive.

Mu Wanjun was still driving the helicopter.

Shen Shuli has consumed a lot of mental energy in the past few days and needs to recuperate.

So I folded up most of the seats at the rear of the cabin, took out the warm and thick bedding and lay down to rest.

There is also a curtain hung. When the curtain is drawn, there is an independent small space behind it, so there is no need to worry about the embarrassment of having two men together.

Xiao Yuxuan sat in the co-pilot seat and chatted with Mu Wanjun from time to time, and at the same time consolidated his knowledge on how to fly a helicopter.

Xie Chengyuan also sat in the front chair to rest.

Shen Shuli couldn't fall asleep for a while, her consciousness immersed in the busy space.

This time the space upgrade directly gave one hundred acres of spiritual fields.

Shen Shuli had to plant the food quickly so that it wouldn't go to waste.

This time, Shen Shuli directly took out the fifty acres of spiritual field connected to the pasture, continued to plant pasture grass, and prepared to raise horses, cattle and sheep in large quantities.

Even if the northern barbarians today cannot afford to raise a large number of cattle, sheep and horses, there must be a lot when added up.

Shen Shuli had to quickly produce the forage grass for use.

In order to avoid the situation where the livestock had no food or fodder, she was reluctant to feed them all with spiritual fruits and vegetables.

There are more than 300,000 people on the island who need to be fed.

Even if it is used to feed the army, it is better than feeding it to livestock!

The crops planted a few days ago just happened to be ripe, and Shen Shuli used her mind to quickly harvest and store them.

The food stored in the space can last for a while, so we don’t plan to grow any crops in the next few days.

There are currently a total of one thousand acres of spiritual fields in the space.

Previously, the number of spiritual fields was small, and they are gradually increasing.

Shen Shuli only used five acres of spiritual fields to grow medicinal herbs.

Now we are planning to expand the medicinal fields and set aside at least one hundred acres to grow various herbs.

One hundred acres are used to grow a variety of fruits and vegetables.

There are also some special fruits, such as strawberries, watermelons, grapes, etc. that need to be planted in spiritual fields.

Another 100 acres have also been allocated specifically for growing these fruits.

The ranch was also expanded to 200 acres.

Such a large area should be enough for the animals to move around.

If the pasture area is not enough, there are mountains next to it.

Animals that like to live in the mountains can also move freely.

The river in the space was divided into new areas by Shen Shuli.

The mountain range now covers more than 60,000 acres.

Shen Shuli made the big river flow from the middle of the mountain into more than a dozen small rivers that shuttled through various mountain ranges.

Then they converge into two large rivers at the bottom of the mountain, surrounding the pasture and spiritual fields, forming a good cycle.

It will not cause a particular location to be particularly short of water.

The remaining 500 acres of spiritual fields.

Shen Shuli is not planning to grow food for the time being.

Anyway, the food stored in the space is enough to feed more than 300,000 people for nearly a month.

But the amount of cotton on the island was too small, so Shen Shuli planned to use all 500 acres to grow cotton.

After planting all the seeds, Shen Shuli mixed together all the spiritual spring water below level ten that she had saved and diluted it with water.

All the spiritual fields and mountains in the entire space were watered in small amounts.

In this way.

Shen Shuli's tragic discovery.

The amount of water in the space river is decreasing visibly.

"Oh my god, there is more and more land in space. Is the water supply going to be urgent again?"

Shen Shuli felt like crying but had no tears!

Just thinking about it.

Shen Shuli suddenly discovered that the originally cloudless sky was suddenly covered by dark clouds.

Not long.

It started to rain heavily!

Half an hour later.

The heavy rain turned into light rain!

Shen Shuli was once again shocked by the cool operation of the space!

"Could it be that after the space is upgraded to level ten, it really becomes the same as the outside world, a complete small world that can reproduce itself?"

Shen Shuli was so excited that she suddenly found that her soul, which had been feeling nothing before, could suddenly sense the cool feeling of rain falling on her body!

She quickly looked down.

But suddenly discovered!

I don't know when my body unexpectedly appeared in space!

That’s right!

It was a translucent consciousness just now, but now a real body appears in the space?

Just a few breaths of time.

Hair, skin and clothes were soaked.

This feeling is exactly the same as being caught in the rain in the real world outside!

Shen Shuli couldn't help but breathe heavily at this moment.

Since the space can be upgraded.

Shen Shuli has been wondering when the space will be truly open to people.

But Shen Shuli tried to upgrade several times, but always ended in failure.

I didn't try it again the next few times.

Subconsciously, we have accepted the concept that humans cannot enter space.

But now!

Her body was able to come in somehow!

Shen Shuli was worried that this was an illusion.

She quickly tried to exit the space and take a look.

She actually discovered that she, who was originally a clean and healthy person, had now become a drowned chicken!

But she doesn't mind at all!

Even very happy!

This is definitely more exciting news than the space upgrade.

This means.

Shen Shuli has an absolute way to save her life!

But she still needs to study carefully whether this space has a limited time for entry each day.

And the place where you appeared after entering is still the same place, or something like that.

These all need to be clarified.

Shen Shuli was worried that someone would notice something unusual, so she quickly took out a set of clean clothes from the space and used her internal energy to dry her hair.

Then he quickly forced himself to rest. He had just been tossing and turning in the space for most of the day and had not recovered much of his mental strength.

I won't be in good condition when I work later.

An hour later.

The helicopter then flew into the sky above the vast grassland.

Today's grasslands lack the prosperity they had in summer.

There was only frozen dry grass and howling cold wind.

The grassland is too vast.

Mu Wanjun drove on the grassland for a long time.

Finally, we found a place where people were active at the foot of a mountain.

There are a few tents similar to "yurts" that are unique to the northern barbarians.

"These people only have a dozen horses in total. Should we take action?" Mu Wanjun looked down and asked Shen Shuli.

Shen Shuli said without hesitation: "Of course! Take them all, leave nothing behind."

Mu Wanjun did not hesitate and immediately lowered the helicopter to a farther location, fearing that the people inside might hear the noise and come out to check.

"Ah Jun, you and Prince Xuan will stay here to meet us at any time. Brother Cheng Yuan can just accompany me."

Mu Wanjun and Xiao Yuxuan nodded and said, "Okay, be careful."

Get out of the helicopter.

Shen Shuli immediately felt that the cold wind here was so biting.

The frozen dry grass and soil on the ground were a bit rough on the feet.

"The cold wind here is indeed stronger." Shen Shuli shuddered.

Xie Chengyuan quickly stood in front of the wind to block the wind for her: "You walk behind me."

Maybe it's too cold outside.

There is no one around.

The horse stable is in the middle of the tent, which can better block the wind.

It can be seen that these northern barbarians attach great importance to these livestock.

Shen Shuli didn't want to waste time, so she went directly with Xie Chengyuan.

Pulling him to run quickly: "It's okay, I'm not cold, let's not waste time, let's do it as soon as possible."

Xie Chengyuan nodded, and used his Qinggong to fly towards the stable with Shen Shuli.

Shen Shuli did not approach the stable directly.

Now she can take what she wants through the ground within the maximum distance of fifty meters.

It was the first time that Xie Chengyuan saw Shen Shuli put a living thing into the Qiankun bag.

He always thought.

The Qiankun bag can only collect dead objects.

It was just a casual remark before, but I didn’t expect it to actually work!

So it was quite amazing to watch.

Shen Shuli didn't give him time to be in a daze, and quickly pulled him back.

From appearance to disappearance.

There was less than two minutes.

No one in the tent was alarmed at all.

After Shen Shuli and Xie Chengyuan boarded the plane, Mu Wanjun immediately started the helicopter and continued to fly deep into the grassland.

The tribes we encountered along the way were small or medium-sized.

The number of livestock they raise also varies.

But Shen Shuli took all of them into the space without hesitation.

These foreign races are mortal enemies of Dayong, so there is no need for Shen Shuli to hold back.

Shen Shuli did not see with her own eyes how the Northern Barbarian Army massacred the city after they invaded Dayong.

But one can imagine the tragic scene.

She was only taking away their food and had not yet killed them.

I have shown mercy!

Walk and stop.

It took a whole morning.

The four of them finally found the largest and most densely populated tribal gathering place of the Northern Barbarians so far.

Four tall and thick walls were built on the outermost side, making it look like a city with tight defenses.

There is a big river outside the city, but the river is frozen.

Water is definitely a very important resource on the grassland.

This place has the largest water source in the grassland, so it will naturally be occupied by the Northern Barbarian royal family.

The ordinary people who depended on the royal family for their lives also gathered together for warmth.

This royal city is larger than ten capital cities.

It is estimated that most of the northern barbarians live here.

Shen Shuli and her companions could not use the previous method to openly take away the livestock they raised.

We have to find another way.

Mu Wanjun suggested, "Should we disguise ourselves and enter the royal city?"

Xie Chengyuan felt that this method was not feasible, and reminded him: "There are almost no outsiders coming to this grassland."

"If we show up rashly, we will definitely attract their attention, and they will probably see through our disguise quickly."

Xiao Yuxuan agreed with Xie Chengyuan's opinion: "Well, Master Xie is right, this method is not feasible."

Mu Wanjun spread her hands helplessly and asked, "What should we do? The military strength of this royal city is at least 50,000. Although it is not a lot, it is definitely a huge number for us."

Shen Shuli leaned back in her chair, closed her eyes and relaxed.

She listened to the conversation between the three people and was silently thinking about countermeasures.

"Why not use poison!" Shen Shuli suddenly opened her eyes and suggested.

This is the territory of foreign enemies.

Shen Shuli will not be soft on her enemies.

Using poison can definitely achieve twice the result with half the effort.

The eyes of Mu Wanjun and the other two suddenly lit up!

"It's better to use poison!" Mu Wanjun raised both hands in agreement.

Xie Chengyuan and Xiao Yuxuan had no objection and thought it was a good idea.

"How can we poison the people of this city quietly without harming the animals?"

Shen Shuli couldn't bear to hurt the cattle, horses and sheep that the northern barbarians had carefully taken care of.

She has to use all her income to support herself in the space.

Then I can bring them back to the island to expand my army.

Xie Chengyuan suggested: "I will go into the city alone at night and poison the water source?"

Shen Shuli shook her head: "What if the animals also drank the poisonous water? I don't want to lose even a little bit."

Xie Chengyuan was in a bit of a dilemma.

He really couldn't think of a solution that would satisfy both parties at the moment.

Mu Wanjun raised her hand and spoke actively.

The three of them looked at her expectantly, wanting to know what solution she had.

"Hehe, this princess's poison technique has reached the pinnacle!"

"You have to believe me. I can definitely develop a perfect poison that is specifically targeted at humans and won't harm animals!"

Upon hearing this, Shen Shuli and the other two all looked at Mu Wanjun with admiration.

In this way.

It couldn’t be better!

Shen Shuli said quickly: "There are many poisons in my Qiankun bag. See if there is anything you need? Study it carefully."

Mu Wanjun raised her chin proudly: "Don't worry, just leave it to me!"
