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

In the middle of the river, sailboats with white sails sail on the water.

It's just that unlike the previous time, when sailing relied on the wind, the sailing of the sailboat at this time basically has nothing to do with the sails and the wind.

The sailor standing at the stern of the sailboat held the 'rudder' made by Han Cheng and the others with both hands, shaking it back and forth, left and right.

With his rocking, the sailboat began to move forward.

At the same time, after such a period of familiarity, this person has become quite proficient in the control of this new type of tool.

In addition, I have previous experience in rowing with oars, so I can control the direction of the boat well with this 'rudder'.

The lame and the others stood on the shore, watching such a scene, and laughed from ear to ear.

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

Han Cheng also had some smiles on his face, but compared to the smiles of the lame and others, it was still a little different, and it seemed a bit far-fetched.

Because he knew that the thing he and others were making now was not a rudder, but a tool called a turret.

Although the oar can also control the ship to steer, it is obviously not as functional as the rudder.

Otherwise, in later generations, people would not have installed rudders on large ships for steering, but would have used oars.

The oars were obviously not very suitable for installation on sailboats.

Now it looks like a good thing to propel a sailboat forward, but in fact the current sailboat is just a model or a miniature version of the sailboat.

The boat is small, and the oar can naturally be pushed, but when the ship is large, it is not possible to use the oar.

However, the unexpected discovery of the oar at this time is not a bad thing.

Because in the tribe there are other small boats besides sailboats.

Just because the oars on a sailboat are not suitable does not mean that the rest of the boats are not suitable for the oars.

Wait a minute, have some oars made and mounted on the slightly modified tribal boats.

In this way, there will be no more boats propelled by oars than just oars, but also boats propelled by oars.

As for the rudder......

Han Cheng's gaze once again turned to the sailboat running forward under the impetus of the oars in the river, and some smiles appeared on his face.

After going through the confusion circle of the rudder turning into a oar at the beginning, Han Cheng's thinking at this time has become clear.

This device, which was born out of a fish's tail, now seems to have two functions, just like a real fishtail.

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

On galleons, the first function is basically not used.

Because I don't know how big an oar it takes to propel the galleon.

So what needs to be done now is to further improve on the existing basis, remove the first function, and only keep the second steering function.

After thinking like this in his heart for a while, carefully tracing his thoughts, Han Cheng felt that there were no other problems, and after looking at the lame and the others, he opened his mouth and told them about the things he had considered and knew.

Of course, when saying this, the words used are naturally exquisite, and the words that should be said and those that should not be said are naturally not revealed.

After listening to Han Da Shenzi's words, the happy lame and others realized that what they and others had made was not a rudder, but a oar, and it was still very different from what Shenzi wanted to achieve.

But even so, the lame and the others still felt very happy.

Because through this busyness, even if they didn't get the expected results, they still got a lot of things, which will bring a lot of changes and convenience to the tribe.

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

Here in the distant Jinguan City, there are no wooden hibiscus like brocade balls, and there are many gourd shelves with white flowers.

The gourd is a good thing, whether it is made into a scoop or hollowed out to make the rest of the container, it is very good.

Moreover, some gourds can still be eaten.

When they are not yet elders, they are taken off and washed, whether they are cut into slices to boil vegetable soup, or cut into shreds and soaked with boiling water, plucked with cold water, and then the cool tone is very good.

Of course, the premise is that you need to choose the right gourd.

Not all gourds are suitable for eating.

Because of the variety, although some gourds can bite when they are tender, they are extremely bitter and not suitable for eating at all.

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

It's not easy to distinguish between them.

However, such a thing cannot stump the Qingque tribesmen who have a strong desire to eat.

In front of a large group of foodies, this is not a matter at all, those gourds that look no different from the gourds that are not bitter are arranged clearly.

The surrounding area of Jinguan City is also busy at this time.

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

Unlike the main tribes in the north and other places where the grain is harvested close to the roots, the people here in Jinguancheng only focus on the ears of rice when they harvest ripe rice.

Everyone held the ears of rice in one hand, and with the sickle in the other, they pulled not far from the bottom of the ears of rice, and easily cut off the ears of rice.

The main body of the rice ears with green leaves is still here.

In the process of harvesting and walking, everyone seemed to be more careful, and tried to do as little as possible to hurt the main body of the rice.

This is because these empty rice, after a while, will be able to grow ears and bear fruit again.

Long Legs put down a large handful of rice ears in his hand, straightened his waist, and took a short rest, and the scene of surrounding labor also came into view.

Wielding sickles, plump golden ears of rice......

Such a scene made him feel refreshed.

It's just that after remembering that Miko wasn't here, he couldn't help but feel a little unsteady in his heart.

He stood here for a moment's rest, then bent down again and quickly harvested.

The Son of God is not here, and he has entrusted himself with the great responsibility, so he needs to do things beautifully no matter what!

……

The Iron Mountain residential area here is always full of the smell of fireworks.

The black coals were piled up there, and in some places there seemed to be some sparkle in the sun.

Someone shoveled the edge of the huge pile of coal, shoveled it up, carried it to a small cart that had long been dyed and could not see its original color, loaded it with the coal, and then pushed it to a smoking stove......

"Bang dang!"

"Bang dang!"

It's not crisp, or it can be called a dull sound, and it keeps ringing.

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

There are sparks that splash around as they hit.

After a while, the second senior brother, who was holding a sledgehammer in both hands and shirtless, stopped.

The man who was holding the piece of iron with tongs quickly put the blackened piece of iron back on the burning stove and continued to heat it with the fire.

The second senior brother holding the hammer put down the sledgehammer in his hand, wiped the sweat on his forehead with one hand, and stood there with the handle of the hammer in the other hand, watching the burning coal in the furnace burst into a scorching fire under the impetus of the bellows.

The second senior brother is strong in his own right, and the first iron tool in the tribe was made out of iron sand by him and Shenzi, so he is very interested in smelting iron and making iron products.

Han Cheng asked him to come and take charge of the Iron Mountain Residential Area, which was also very much in line with his wishes.

Of course, he can't always strike iron here, and he has to spare a lot of time every day to deal with the rest.

As someone who had been in the tribe for a long time, he didn't find it tricky to deal with these things.

Different from the agriculture-based place in Jinguancheng, the Tieshan residential area, which is positioned as an industrial residence, looks more prosperous and lively.

Also, just by looking at the many smoking stoves, the fiery molten iron, and the burned red iron, you can feel the red fire.

In the midst of some of the louder noises, an iron-smelting furnace was turned on, and fiery molten iron flowed out of it......

The second senior brother stood here and watched for a while, and then turned his head to see that the piece of iron on the iron stove in front of him had turned red again, so he no longer looked that way, but began to pick up the hammer again with the cooperation of the person holding the iron tongs on the side, and began a new round of hammering against the iron in front of him......

Things will not continue to happen because of the second senior brother's lack of attention.

It's like there are endless things happening beyond a person's limited gaze.

In the iron-smelting furnace, the dark red molten iron was already running clean.

There was a mold on the side of the stove, and the trough inside had been filled with solidified molten iron.

A few people are busy here.

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

After a while, he walked over to the side, cleaned his hands, and then took out a wooden box.

He carefully opened the wooden box, reached out and took out a notebook, then opened it, and turned a few pages back.

The man looked at it earnestly, and from time to time he would write some numbers on the ground with a branch.

After a while, he got a new number, which he wrote neatly in his notebook with a pen.

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

The time it takes to smelt a furnace of molten iron has not improved much.

Even in this process, I have made as many changes as possible, but the results are still extremely limited.

People always want something better.

At the beginning, my tribe got coal and began to use coal to smelt iron, and at that time, I and others felt that this coal was much better to use than charcoal.

But after a long time, I gradually felt that coal was not very easy to use, and wanted to make iron smelting faster and better on the existing basis......

Sitting here stunned and thinking for a while, Han Youli withdrew his gaze from the notebook, and put the notebook back into the box carefully and preciously, and after putting the box away, he participated in the labor.

It's just that in the process of labor, he still seems to be preoccupied, constantly thinking about this matter.

"Courteous! Hurry up and get to work! Don't be stunned! ”

The people who worked with him saw that he was always distracted, and even couldn't help but remind him.

Judging from past experience, as long as he shouts like this, Han Youli will immediately hurry up and work hard, even after a while, he will once again be distracted.

But this time it was a little different, after being reminded, Han Youli not only didn't feel a little embarrassed as before, but on the contrary, his face suddenly showed a look full of excitement.

"I—I've come up with a way to shorten the time it takes to smelt iron!"

He said to his companion with excitement.

After hearing him say this, the people on the side couldn't help but be stunned, and then they couldn't help but be happy.

"You've thought of a lot of such methods, but now our iron smelting speed is not much faster than before, it's still about ......."

Someone couldn't help but say it out loud.

The people on the side couldn't help but laugh when they heard this.

"This, this time is different......

Han Youli, who was splashed with some cold water, argued for himself.

"You've said a lot of that."

The person who spoke before said with a smile again.

The rest of the people continued to laugh, and the atmosphere seemed joyful.

At least these smiling people feel happy.

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

Han Youli's dark face was a little red.

He continued to argue for himself, but his voice was much quieter than before, and he seemed unconfident.

"Let's hurry up and work, work is important, hurry up and smelt more iron, stronger than the rest!"

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

The rest of the people also responded.

Although Han Youli wanted to verify his ideas now, looking at the current scene, he couldn't say anything, so he had to hold back the eagerness in his heart and work patiently, ready to wait until the evening or when the rest were a little free to take the time to verify his ideas.

"Have you figured it out?"

At this moment, a different voice came.

Han Youli turned around and saw the second senior brother coming over.

Looking at the second senior brother and listening to the second senior brother's inquiry, Han Youli seemed very hesitant, but in the end he nodded heavily.

"Then you just let it go, I'll arrange for the rest of the people to do it for you."

Unexpectedly, the second senior brother not only didn't blame him, but also said such a thing and made such a decision.

This made Han Youli unconsciously lower his head, and he raised it all of a sudden......
