"Ari, what should we do?"

Mu Wanjun stood by the window and looked down through a telescope.

Many northern barbarians were holding long whips and beating the ordinary enslaved people, as if they were animals, without mercy.

Those people of Dayong who were being beaten did not dare to cry out in pain, otherwise they would be whipped even more severely.

Xie Chengyuan tried hard to suppress the anger that was about to erupt in his heart.

Because he is alone now, even if he is personally strong, he cannot fight against the more than 5,000 Northern Barbarian Army below.

It is also impossible to rescue the people of Dayong.

Except for Qing Grant Mansion.

The other prefectures and cities around are also inhabited by northern barbarians.

Even if the people of this city could be rescued, the northern barbarians in other nearby cities would still attack the people of Qing Grant Prefecture after discovering something unusual.

...

...

By then, the northern barbarians' means of revenge may be even more bloody and brutal!

Since there is no perfect plan, we cannot act rashly.

Xie Chengyuan and Xiao Yuxuan also set their sights on Shen Shuli.

Shen Shuli thought for a moment before she spoke: "We need to complete our mission first, and then think of a solution."

The main purpose of their mission was oil.

If we fail to obtain the oil and alert the northern barbarians first, not only will the mission fail, but we may not be able to rescue the people of Dayong here.

Mu Wanjun agreed: "You are right, let's find a way to get the oil first, and then think about how to deal with these hateful northern barbarians!"

Xie Chengyuan and Xiao Yuxuan also nodded in agreement.

Xie Chengyuan frowned and asked, "But there are Northern Barbarians down there, and they are guarding the oil wells very closely. How can we break through without alerting them?"

Shen Shuli showed a wicked smile on her face and winked at Xie Chengyuan mischievously.

"Hehe, the mountain man has his own clever plan~"

Xie Chengyuan didn’t know much about Shen Shuli’s strength, and he always thought about things from a mortal’s perspective.

Mu Wanjun knows her best friend's methods.

She smiled and patted Xie Chengyuan on the shoulder, saying, "Don't worry, she has her own ways. All we need to do is wait patiently."

Xie Chengyuan then remembered that Shen Shuli had a magic weapon in her hand!

His tightly furrowed brows slowly relaxed, and he chuckled, "I was too obsessed with it, and almost forgot that Ah Li had a magic weapon in his hand."

Shen Shuli said: "You guys find a safe place to rest first, and think about how to deal with these northern barbarians. I will go to collect the oil alone."

The three of them nodded.

Mu Wanjun landed the helicopter.

Shen Shuli left the helicopter alone and quickly approached the location she saw.

Mu Wanjun flew a helicopter directly to the top of a nearby mountain, where she could have a panoramic view of the entire troop deployment of the oil mine below the mountain.

The three of them discussed countermeasures.

After seeing the helicopter leave, Shen Shuli came to a secluded place and changed into a combat uniform that was easy to move in.

This is when the action begins.

Shen Shuli secretly came to the location closest to the oil field and with the least Northern Barbarian soldiers and began to dig a hole.

Shen Shuli only dug three meters wide, three meters long and one meter deep each time to avoid digging into groundwater.

More than two months ago, the whole world had a three-month rainy season.

No matter how dry the northern region is, there is definitely plenty of groundwater resources.

Only by getting close to the oil well can we avoid digging into groundwater to the greatest extent possible.

The fact that the oil wells can continue to produce oil suggests that the groundwater nearby is probably not that abundant.

Or maybe it's all rock layers, avoiding the groundwater level.

So Shen Shuli didn't want to be too far away from the oil well.

Using space to dig a well will definitely not make any sound.

Shen Shuli dug to a depth of more than 100 meters without encountering any groundwater layer.

And they are all rock layers.

It just confirmed Shen Shuli's guess.

The area nearby should be all rock layers.

Shen Shuli became much bolder.

Her space is now at level seven, and she can move four hundred cubic meters of objects at a time.

She controlled her mental power and dug a layer of soil that was five meters long, five meters wide, and sixteen meters deep at a time.

The speed increased significantly instantly.

Fortunately, this area is covered with rock layers.

There are too many building materials such as stones, bricks, wood, etc. stored in the space recently.

There is no more room for these rocks.

Shen Shuli could only temporarily pile these things on a mountain range outside the warehouse.

But Shen Shuli was surprised to find out!

The space actually absorbed all those stones!

The mountain range of more than 3,000 acres has undergone a slight change again!

The space shows signs of upgrading!

She really didn't expect that this stone layer that she didn't care about would be absorbed by space!

What a pleasant surprise!

Shen Shuli became more motivated.

As long as her mental strength is not exhausted, she will not rest and will keep digging!

finally.

The space vibrated slightly with a humming sound, and it was accidentally upgraded!

There has been no room for upgrading for a long time, and I finally reached level eight!

According to past experience.

Now the same mineral resources have been absorbed by the space to saturation, and no matter how much more is absorbed, the space will not be able to continue upgrading.

But it will still cause the mountains in the space to slowly expand.

The previous mountain range of more than 4,000 acres has now expanded to more than 5,000 acres.

The spiritual field was expanded to 90 acres, the spiritual spring water was upgraded to level nine, with a daily output of 18 liters, and the warehouse was upgraded to the size of nine football fields.

Shen Shuli left the mine, found a sheltered location, moved out a tent and lay down to rest.

I drank a lot of level eight spiritual spring water to restore my physical and mental strength.

Then he closed his eyes, sank his consciousness into the space and continued to be busy.

The newly added spiritual fields were planted with crops, and the extra thousand acres of mountains were also sown with a variety of plant seeds.

Shen Shuli suddenly discovered.

The space has actually changed a lot.

In the original space, there was only daytime, but no sun.

It's like being in a space without light but always bright.

But now, a golden sun appeared in the sky!

The sunlight shines into the space, as if the pores are more relaxed.

Shen Shuli quickly moved out all the electrical appliances in the space that needed to be charged by solar energy.

She was pleasantly surprised.

The sun in space has exactly the same energy as the sun in the real world outside, and it can actually charge those electrical appliances!

"Does this mean that from now on, there will be a distinction between day and night in this space?" Shen Shuli thought expectantly.

It didn't take long.

Shen Shuli continued to work.

The newly added 1,000 acres of mountain range are irrigated with diluted spiritual spring water.

Working wholeheartedly.

Shen Shuli discovered that Batian, Junlin, Yuluo and Baishuang (the giant white dragon snake) were all chasing after her.

Especially hoarfrost.

It is simply an extraordinary species.

It took Shen Shuli a long time to build up some emotional connection with it, and she was able to communicate with it simply using the beast taming technique.

But it looked down on the big brown bear and the tiger parents and didn't like to play with them.

The snake swam alone in the mountains all day long.

Only when Shen Shuli appeared would it take the initiative to approach her and play with her for a while.

Shen Shuli also knew that the extraordinary species Bai Shuang was most likely the only one in the world, and there was no way to find a playmate for it.

What's more, it is a female snake.

It certainly doesn't look down on other weak male snakes.

Otherwise, Shen Shuli really hoped that it could produce some mutant dragon snakes.

Shen Shuli was still very generous to Bai Shuang.

It is fed some undiluted spiritual spring water every day.

This guy is indeed an extraordinary species.

With the spiritual spring water to temper its body, its body grew another two meters in just three months!

Fortunately, there is an extra mountain in the space.

Otherwise it won’t be enough for it to turn over.

As long as Bai Shuang wants to get close to Shen Shuli, it will not allow Batian, Junlin and Yu Luo to get close to Shen Shuli.

Otherwise, he would beat the three little ones with his tail without mercy.

The three little ones didn't dare to resist.

I really can't resist.

If Bai Shuang wanted to, she could swallow all three little ones in one bite.

So the three little ones are just little brothers in front of Bai Shuang.

The three little ones have to catch food and feed Baishuang every day.

She is simply a queen-level existence.

But Shen Shuli also dotes on the three little ones.

They will also be fed with a lot of spiritual spring water, and even the six little tiger cubs will not be treated unfairly.

In just a few months, the six little tiger cubs have almost caught up with their parents in size.

Their physique is actually stronger than that of tiger parents.

This is the benefit of strengthening your body from a young age.

After playing with the pets for a long time, Shen Shuli let them go and play on their own as she had other important things to do.

Rested for four hours.

After Shen Shuli recovered to full strength, she immediately exited the space and continued to work.

It took almost a day to dig.

Shen Shuli had only dug more than 1,200 meters.

Unsure of the exact location of the oil layer, Shen Shuli had to slow down and dig only one meter deep at a time.

It took two hours of persuasion and coaxing.

Shen Shuli could finally smell the faint smell of petroleum.

"We are finally going to get to the bottom of it!" Shen Shuli was very excited.

But she just remembered something at this moment, and her expression changed slightly.

She did not continue digging, but quickly left the deep well, then took out the walkie-talkie to contact Mu Wanjun.

Shen Shuli: "Ah Jun, Ah Jun, where are you? I suddenly forgot something."

Mu Wanjun replied quickly: "What's wrong, A-Li? Did you forget something?"

Shen Shuli suddenly thought that Xie Chengyuan must be beside her. She thought about it and then said this.

"I'm almost reaching the oil layer, but there's no oil container in my bag."

Mu Wanjun and Xiao Yuxuan only then remembered this.

Shen Shuli's space warehouse cannot directly store ** and other materials.

If you install ** directly.

**The default is to directly pave the entire warehouse bottom and then slowly raise it.

By then, ** will submerge all other supplies in the space.

This is the only drawback of Shen Shuli’s space warehouse.

"I also forgot about this matter. Where can we find so many containers to store oil now..." Mu Wanjun was very worried.

Xiao Yuxuan and Xie Chengyuan could both hear the conversation between the two.

We are also thinking quickly about solutions.

Xie Chengyuan looked at the oil mine below and suggested, "Why don't we borrow their barrels?"

The oil produced from that oil well would be stored in large wooden barrels that were twice as big as a bathtub.

This is already the largest container of this era.

There must be a lot of oil drums in the oil field.

But it is definitely not enough for Shen Shuli to use, they have to find a way to get a large batch.

Shen Shuli thought of the container and suddenly came up with a better idea.

"You don't have to take risks, I have a better way!" After Shen Shuli said this, she sank her consciousness into the space and started working.

The space has just been upgraded, and an additional three hundred acres of space has been added.

And there is no upper limit to the height of this warehouse.

At least within the range visible to Shen Shuli's naked eyes, she had not seen where the height limit was.

Shen Shuli immediately began to mix a large amount of yellow mud, preparing to build a circle of extremely strong and thick walls in the warehouse.

Isolate a separate space specifically for storing oil.

To avoid too much oil and too much pressure for the wall to withstand.

This wall must be as thick as possible.

At least the closer to the bottom, the thicker it needs to be.

Fortunately, there happen to be quite a few rock layers in the space that are thick and large enough.

Shen Shuli directly used her mind to control the construction and began to lay a large square base in the open space in the warehouse.

Every time a warehouse is expanded, it is built around the original warehouse.

That is to say.

If the space continues to upgrade.

This area will continue to expand, and Shen Shuli has no way to save time and materials by relying on any two walls of the space.

Otherwise, when the space is upgraded and expanded again in the future, the other two walls will definitely move outward and the oil will leak out directly.

Shen Shuli had to build an independent space.

She plans to build a square oil tank, which will save time and effort.

There was not much clay in the warehouse.

Shen Shuli directly dug clay from the mountains in the outside space, added various dry straws, glutinous rice flour and other materials, added water and made mud.

Working with your mind will definitely be more efficient.

Shen Shuli can prepare at least ten tons of adhesive at a time, and after preparation, it will be directly transported to the designated location in the warehouse.

First, spread the mud on the ground, and then use mental power to control the huge rock slab and place it directly on the mud to form a square base.

Where there are gaps, fill them with suitable small stones and then seal them with thick mud.

The length and width of the entire base are at least twenty meters.

Shen Shuli was not proficient in mathematics and did not know how to calculate the wall thickness of an oil storage tank as big as a football field.

But in order to avoid going through all the trouble, she decided to make it as thick as possible at one time.

If it is still not thick enough, she can add another circle on the outside.

Anyway, for her, working in the space is not tiring at all, it's just a little mentally demanding, and she has the full cost of trial and error.

The stones in the warehouse were originally prepared for the military camp on the island, but after Shen Shuli used them up, there was not enough.

It just so happens that the oil wells outside are all covered with thick layers of rock.

It was more convenient for Shen Shuli to go directly to the oil well and use space to cut it into the thickness and width she needed.

Now that the space has been upgraded to level eight, Shen Shuli can move 500 cubic meters of objects at a time.

She chose to cut the rock layers into blocks of ten meters wide, ten meters long, and five meters high, and built the oil depot in a staggered manner.

unconsciously.

The oil well, which was originally only five meters wide, was hollowed out by Shen Shuli, like a huge abyss.

If someone stood on it and looked down, he would probably be so scared that his legs would go weak and he would fall directly into the abyss.

Mu Wanjun and the other two had been separated from Shen Shuli for a long time and suggested going to find her.

Wait until you get closer.

The three were surprised to find that a huge abyss had appeared on the originally tall and barren mountain.

Even though Xie Chengyuan and Xiao Yuxuan were very powerful, they still felt dizzy when standing in front of this huge abyss, and were so scared that they couldn't help but retreat again and again.

Mu Wanjun didn't expect that these two grown men could be scared like this.

She walked over casually, wanting to experience it for herself.

But she overestimated her psychological endurance.

Standing in the abyss and looking down from a helicopter are definitely not the same feeling!

Mu Wanjun's little face turned pale with fright in an instant.

Xiao Yuxuan quickly pulled her away and patted her on the back in a bad mood: "What are you trying to do? Are you scared?"

It took Mu Wanjun a long time to come back to her senses. At this moment, she just wanted to get away from that horrible place.

Xie Chengyuan still has lingering fears about that abyss.

It occurred to him in an instant.

Would Shen Shuli also be afraid when facing such an abyss?

He immediately looked around for the person, but couldn't find him anywhere.

Only one tent was found nearby.

It was obvious that the tent was taken out by Shen Shuli, but there was no one in the tent.

He immediately asked Mu Wanjun: "Ali is not here, could she be down there?"

Upon hearing this, Mu Wanjun and Xiao Yuxuan also hurriedly looked for Shen Shuli.

Still not found.

Mu Wanjun guessed: "She should be down there?"

After saying that, he quickly used the intercom to contact the other party.

"Ali Ali, where are you?" Mu Wanjun called out.

After receiving it, Shen Shuli immediately replied: "In the deep well, what's wrong?"

Mu Wanjun and the other two finally breathed a sigh of relief after hearing that Shen Shuli was safe.

She was worried that Shen Shuli was scared being alone down there, so she wanted to go down and accompany her.

But when she thought of that abyss, her legs went weak and her eyes turned red with anxiety.

"Brother Xuan, this place is so scary. A'li must be so scared all by herself. I, I, I, I want to go with her but I don't dare... wuwuwu..." Mu Wanjun couldn't help sobbing.

Xiao Yuxuan had never seen Mu Wanjun cry.

I felt heartbroken instantly.

"Don't worry, I'm here. I'll go down and accompany her right away."

"Aren't you afraid?" Mu Wanjun clearly saw that he was still afraid of that place.

This is an instinctive physiological reaction that few people can completely overcome.

"You two just stay up there, I'll go down to accompany her." Xie Chengyuan said.

He also wanted to go down to look for Shen Shuli. He couldn't leave Mu Wanjun here alone.

The Northern Barbarian Army is right next to us. It's too unsafe.

Prince Xuan must be allowed to accompany and protect the princess.

"Forget it, why don't we drive a helicopter down? I think there should be a place to park the helicopter down there." Mu Wanjun suggested.

The helicopter has lights to illuminate the area below, so it won't be too scary.

And they are still in the helicopter, so they will feel psychologically safe.

Xie Chengyuan did not refuse when he heard this. This was a good idea.

Xiao Yuxuan naturally had no objection.

They originally didn't know what kind of environment Shen Shuli worked in.

Now I know.

Naturally, she couldn't face it alone.

This huge abyss is so deep that it seems impossible to see the bottom. It makes men's legs go weak when they see it.

How can they rest assured that Shen Shuli will be alone?

Even if I could just stay with her, it would be fine.

Mu Wanjun hurriedly urged the two to get on the helicopter.

After a long period of psychological preparation, he finally drove the helicopter into the huge mouth of the abyss.

"Ari, where exactly are you? We'll fly a helicopter to find you."

Shen Shuli was a little surprised. She didn't expect them to come to her.

Her consciousness quickly exited the space and replied.

"I've turned on the light. You can see it about 500 meters down. Go slowly and don't hit the rocks."

"Okay, I understand."

Mu Wanjun slowly flew down a few hundred meters and finally saw a searchlight shining towards the helicopter.

Shen Shuli had just cleared a platform for the helicopter to land.

After opening the hatch, Shen Shuli walked in and looked at the three people curiously: "Why did you come down suddenly?"

"It's been almost a day, and we've been very worried about you, so we suggested coming here to accompany you. Drink some water quickly, you see your mouth is dry and chapped." Mu Wanjun looked at Shen Shuli with concern and handed her a cup of hot tea.

Shen Shuli couldn't help but laugh.

My bestie is really exaggerating.

She has been drinking spiritual spring water to replenish her energy, so how could her lips be chapped?

Her skin won't get flaky even if she doesn't drink water for ten days.

But she knew that her best friend felt sorry for her, so she didn't refute it and quickly drank a few cups of tea.

Xie Chengyuan looked at Shen Shuli, who was wearing strange clothes, with mud on her face and clothes.

He handed her a warm, wet towel and asked her to wipe her face: "How did you get yourself into such a mess? Wipe your face quickly."

Chen Shuli took the handkerchief with a smile, and feeling its warmth, she smiled at Xie Chengyuan with her eyes bent: "Thank you, I'm building a wall in my Qiankun bag, it's a bit dirty indeed."

"It's still very cold at this depth. Are you sure you want to stay here?" Shen Shuli asked with concern.

The three of them nodded in unison.

Shen Shuli was helpless.

She took out the tent and placed it on the platform outside, and also took a lot of food, firewood, charcoal, quilts, blankets and other cold-weather supplies.

"Then you can light a fire here to keep warm. If you are still cold, go back to the ground."

"Okay, then are you cold while working? Why not take a break and eat something?" Xie Chengyuan looked at Shen Shuli with a distressed look in his eyes.

Shen Shuli smiled and shook her head, and reached out to hold Xie Chengyuan's hand, letting him feel the warmth of her palm.

"Don't worry, I'm not cold at all. If you don't believe me, feel it for yourself."

She really didn't feel cold.

She was wearing warm clothes made of the most advanced cold-resistant technology fabrics, and she didn't feel cold at all.

Otherwise I would have been unable to bear it and went up long ago.

Xie Chengyuan could feel Shen Shuli's soft and warm hands, and a smile secretly appeared on the corner of his mouth unconsciously.

"If you're tired, come over here and take a rest and eat something."

"Okay, then I'll go to work first." Shen Shuli smiled and nodded in agreement.

Her oil depot is only ten meters high, so it’s still early.

There must be a huge amount of oil here. Since Shen Shuli came all the way here, she must take away at least half of it.

So this oil depot must be built tall and large enough.

Otherwise, once the last layer of shackles was broken, the oil would gush out and all flow outside, and she would not have time to clean up the mess.

Shen Shuli continued working for ten full days and finally built the oil depot to a height of more than 450 meters.

This empty warehouse covers an area of ​​about 300 acres of open space.

Shen Shuli built a square oil tank with a length and width of 450 meters, and the height was temporarily built to 450 meters.

If the oil depot hadn’t been built, Shen Shuli wouldn’t have discovered it.

There is a limit to the warehouse.

About five hundred meters.

Fifty meters of space is reserved above.

Shen Shuli really wanted to know whether the height would also increase when the space was upgraded.
