There were no less than ten people, including Han Cheng, standing by the river in the Qingque tribe.

In the river, sailboats with white sails are sailing on the water.

However, unlike the previous sailing which relied on wind power, the sailing of the sailboat at this time has basically nothing to do with sails and wind.

The sailor standing at the stern of the sailboat held the "rudder" made by Han Cheng and others with both hands and shook it back and forth.

As he rowed, the sailboat began to move forward.

At the same time, after a period of familiarization, this person has become much more proficient in controlling this new tool.

In addition, with previous experience in rowing with oars, this "rudder" can also be used to control the direction of the boat very well.

Bo and others stood on the shore, watching this scene, and laughed so hard that they couldn't stop.

They felt that they had already made the rudder and successfully solved the major problem of steering the sailboat.

There was also a smile on Han Cheng's face, but compared with the smiles of Bo and others, it was still a little different and seemed a little far-fetched.

Because he knew that what he and others were making now was not a rudder, but a tool called an oar.

Although oars can also control the steering of a ship, their functionality is obviously inferior to that of a rudder.

Otherwise, in later generations, people would not install rudders on large ships for steering, but would use oars instead.

Oars are obviously not very suitable for installation on sailboats.

Now it looks like it is very good to use it to propel the sailboat forward, but in fact, the sailboat is just a model or a mini version of it.

If the boat is small, oars can naturally be used to propel it, but when the boat becomes larger, oars will no longer work.

However, unexpectedly discovering the oar at this time is not a bad thing.

Because in addition to the sailboats, there are other small boats in the tribe.

Just because it’s inappropriate to install oars on a sailboat doesn’t mean it’s inappropriate to install oars on other small boats.

After a while, we will have people make some oars and install them on the tribe’s slightly modified boats.

In this way, by the time the tribe has, there will not only be boats propelled by oars, but also boats propelled by oars.

As for the rudder...

Han Cheng's gaze once again turned to the sailboat in the river that was moving forward under the push of oars, and a smile appeared on his face.

After the initial confusion of the rudder turning into an oar, Han Cheng's thoughts had become clear.

This device, which was derived from a fish tail, now looks like a real fish tail and has two functions in total.

One is to push the boat forward, and the other is to turn.

The first function is basically not used on a large sailboat.

Because I don't know how big the oars would be needed to propel the sailboat forward.

So what we need to do now is to make further improvements based on the existing basis, remove the first function and only keep the second steering function.

After thinking about it for a while and sorting out his thoughts carefully, Han Cheng felt that there were no other problems. He looked at Bo and the others and told them what he had been thinking and knowing.

Of course, when saying these things, the words used are naturally carefully considered. What should be said is said, and what should not be said is naturally not revealed.

After listening to what Han Dashenzi said, Bo and others who were overjoyed realized that what they had made was not a rudder, but an oar, and it was very different from what the Son of God wanted to achieve.

But even so, Bo and others still felt very happy.

Because through all this busy work, even if they did not get the expected results, they still got a lot of things, which will bring significant changes to the tribe and bring a lot of convenience.

Seeing everyone's happy faces, Han Cheng's mood also became relaxed. He really appreciated the mentality of everyone in the tribe...

In the distant Jinguan City, there are no hibiscus flowers blooming like brocade balls, but there are many gourd racks with white flowers.

The gourd is a good thing. Whether it is made into a ladle or hollowed out to make other containers, it is very good.

What’s more, some gourds are edible.

When it is still young, pick it and wash it. It is very good whether you cut it into slices for cooking soup, or cut it into shreds, blanch it in boiling water, rinse it in cold water, and then cook it cold.

Of course, the prerequisite is to choose the right gourd.

Not all gourds are suitable for eating.

Some gourds, due to their variety, can be chewed when they are tender, but are extremely bitter and not suitable for eating at all.

Only those gourds that are not bitter, or slightly bitter, can be eaten.

It is not easy to distinguish them.

However, such things could not stump the people of the Qingque tribe, who had a strong desire for food.

In front of a large group of foodies, this is not a problem at all. Those gourds that look no different from non-bitter gourds are arranged clearly.

The area around Jinguan City was also busy at this time.

The rice in many fields is ripe, and people are busy harvesting the rice.

Unlike the main tribes in the north where millet is harvested close to the roots, the people in Jinguan City only harvest the rice ears when harvesting ripe rice.

Everyone held the rice ears in one hand and used the other hand to hold a sickle and pulled not far from the bottom of the rice ears, thus easily cutting off the rice ears.

The main body of the rice ears, with their leaves still green, remain here safely.

During the harvesting and walking process, everyone was very careful and tried their best to do as little damage to the main body of the rice as possible.

This is because these empty rice fields can grow rice ears and bear fruits again after a period of time.

He put down a handful of rice ears in his hands, straightened his back and took a short rest. The surrounding labor scenes also came into view.

Waving sickles, plump golden ears of rice...

Such a scene made him feel relaxed and happy.

But when he thought about the fact that the Son of God was not here, he couldn't help but feel a little uneasy in his heart.

He stood here to rest for a while, then bent down again and started harvesting quickly.

The Son of God is not here and has entrusted the great responsibility to me, so I must do things beautifully no matter what!

…

The Tieshan residential area is always filled with the smell of fireworks.

The pitch-black coal was piled there, and some places seemed to shine in the sunlight.

Someone was using a shovel to dig up coal stones from the huge coal pile, loading them onto a small cart that had been stained so long ago that its original color could no longer be seen, and then pushing the cart towards a smoking furnace...

“Bang!”

“Bang!”

The sound, which could not be described as crisp or could be called dull, kept ringing.

The huge iron hammer kept hitting a piece of red-hot iron.

Sparks flew around as the hammer struck.

After a while, the second brother, with his upper body naked and holding the sledgehammer in both hands, finally stopped.

The person who was holding the iron block with tongs quickly put the blackened iron block back into the burning furnace and continued to heat it with fire.

The second brother who was holding the hammer put down the hammer in his hand, wiped the sweat from his forehead with one hand, and stood there holding the hammer handle with the other hand, watching the burning coal in the furnace emit hot flames under the push of the bellows.

The second brother is strong, and the first piece of ironware in the tribe was made by him and the Son of God using iron sand, so he is very interested in iron smelting and making iron products.

Han Cheng asked him to come and take charge of the Tieshan residential area, which was exactly what he wanted.

Of course, he can't always be a blacksmith here. He has to spend a lot of time every day to deal with other things.

As someone who had been shouldering important responsibilities in the tribe very early on, he did not find it difficult to deal with these matters.

Unlike Jinguancheng, which is mainly an agricultural area, Tieshan residential area, which is positioned as an industrial residential area, looks more prosperous and lively.

Yes, just looking at the many smoking furnaces, the red-hot molten iron and the burning red-hot iron blocks can make people feel such a prosperous fire.

Amidst some rather lively noises, a furnace for smelting iron was opened, and red-hot molten iron flowed out of it...

The second brother stood here and watched for a while, then turned around and saw that the piece of iron on the iron furnace in front of him had turned red again. He stopped looking over there and began to swing the hammer again with the cooperation of the man holding the pliers, and started a new round of hammering at the iron block in front of him...

Things will not stop happening just because Second Brother doesn't pay attention.

It’s like there are endless things happening beyond a person’s limited vision.

In the iron smelting furnace, the dark red molten iron has already flowed away.

There is a mold on the side of the furnace, and the trough inside has been filled with solidified molten iron.

Several people are busy here.

There was a man squatting on the side, writing and drawing with a branch in his hand.

After a while, he walked to the side, washed his hands, and then brought out a wooden box.

He opened the wooden box carefully, reached in and took out a notebook, then opened it and flipped through a few pages.

The man watched attentively, and from time to time he would write some numbers on the ground nearby with a branch.

After a while, he got a new number and wrote it neatly in the notebook with a pen.

He stared at the number for a while, then shook his head and sighed.

There has been no improvement in the time it takes to smelt a furnace of molten iron.

Even though I have made as many changes as possible during this process, the results are still very limited.

People always want something better.

At the beginning, my tribe got coal and started using coal to smelt iron. At that time, I and others felt that coal was much easier to use than charcoal.

But as time went by, I gradually felt that coal was not very useful, and I wanted to make iron smelting faster and better on the existing basis...

After sitting here and thinking blankly for a while, Han Youli withdrew his gaze from the notebook and put the notebook back into the box carefully and preciously. After putting the box away, he joined in the work.

However, during the labor process, he still seemed to be worried and kept thinking about this matter.

"You're polite! Get to work! Stop staring blankly!"

The people who worked with him couldn't help but remind him when they saw that he was always distracted.

According to past experience, as long as he was shouted at like this, Han Youli would immediately get down to work, even if it was after a while, he would not be able to help but get distracted again.

But this time it was a little different. After being reminded, Han Youli not only did not feel embarrassed as before, but on the contrary, his face suddenly revealed an excited expression.

"I, I thought of a way to shorten the iron smelting time!"

He seemed excited as he said this to his companions.

After hearing what he said, the people around him were stunned, and then they couldn't help but laugh.

"You've thought of a lot of ways like this, but our iron smelting speed isn't much faster than before, it's still about the same..."

Someone couldn't help but say this out loud.

The people around couldn't help laughing when they heard this.

"This time is different..."

Han Youli, who felt a little cold water poured on him, argued for himself.

"You've said a lot in that case."

The person who spoke earlier said again with a smile.

The others continued to laugh as well, and the atmosphere became joyful.

At least those who are smiling feel happy.

"This time it's really different..."

Han Youli's dark complexion turned slightly red.

He continued to argue for himself, but his voice was much smaller than before and he seemed to lack confidence.

"Let's get to work. Work is important. We should seize the time to smelt more iron. It's better than anything else!"

One of the people who was working with Han Youli and others spoke like this.

The others also responded.

Although Han Youli wanted to verify his idea right now, he couldn't say anything after seeing the current scene. He had to suppress his eagerness and work patiently, preparing to verify his idea in the evening or when he had some free time.

"Have you figured out a solution?"

At this moment, a different voice was heard.

Han Youli turned around and saw his second senior brother approaching.

Looking at his second senior brother and listening to his questions, Han Youli seemed very hesitant, but finally nodded heavily.

"Then just go ahead and do it. I will arrange for others to do the things here for you."

Unexpectedly, the second brother not only did not blame him, but also said such words and made such a decision.

This made Han Youli raise his head, which he had lowered unconsciously, all of a sudden...
