Shen Wansan looked at the circle drawn by Qi Heng, and was still a little puzzled at first, and his brows furrowed tightly.

However, as he continued to think about it, when he saw the circle as the wheel of a wooden cart, a thought appeared in his mind that he could not even think about.

Shen Wansan looked at Qi Heng in shock, his eyes full of anticipation: "What do you mean by the wheel?" ”

Qi Heng smiled.

Until Qi Heng nodded, Shen Wansan instantly sat down on the ground.

His eyes were glazed, and he was thinking in his mind about what would change when this thing appeared.

In the past, the world's land transportation relied entirely on manpower and horses.

But these motivations need to be rested.

But once something like this does appear, what does it mean?

A means of transportation powered by this steam device was constantly being refined in Shen Wansan's mind.

Speed aside, this thing can operate non-stop for twelve hours.

And the manpower and material resources consumed are very small, and only such a device can drive an unknown amount of goods.

And that's just about shipping.

Militarily, what about life?

The reason why cavalry is important is that in addition to charging in battle, the speed of rapid transfer is the key.

But once this thing appeared, the strategic significance of the cavalry was completely negated.

Looking at Shen Wansan, who was sluggish, Qi Heng said: "This thing, maybe the richest man in the country?" ”

Shen Wansan was already numb at this time, as smart as him, and knew very well that this thing was definitely epoch-making.

He nodded dumbfoundedly.

"Remember the question I just asked you? You're only half right. ”

"Going back a minute, I asked you how to improve efficiency, remember your answer?"

"What I want to tell you is that water vapor is important, stress is also important, but the most important thing is the changed mindset!"

"The efficiency of manual mining is low, can't it be improved by other tools? If you still know how to use farming tools, why can't you change your mind? Could it be that only those tools can be used for ploughing the fields, and this iron-making furnace can only be like this, and cannot be optimized and improved? ”

"And the iron that has been trained can only make farming tools and weapons and armor? How about making the water vapor tool I just mentioned? Water vapor can generate pressure to form power, but what about rivers? When water flows low, can't the inertia of the water flow be converted into power? ”

"The people don't have enough food to eat, but they only have rice and wheat. Do you know why the wasteland north of the city is so heavily guarded? I planted potatoes there, and the yield per mu was 5,000 catties! ”

Speaking of this, Qi Heng didn't say more, he gently patted Shen Wansan's shoulder, and said, "Think about it, you can leave with your brothers tonight, and I won't stop you." ”

"Of course, I'd rather see you in front of the door early tomorrow morning."

After speaking, Qi Heng got up directly and left under Shen Wansan's dull gaze.

Under the firelight of the night, Shen Wansan sat alone on the ground, looking at the simple pattern on the ground, not knowing what he was thinking.

What he heard tonight was too subversive to his perception.

In the past, he thought that doing business was to buy and sell, buy at a low price, and sell at a high price.

But compared with what Qi Heng just said, his ideas are too pediatric.

For such a thing, do you still need to consider where the price is high and where the price is low?

This is the weapon of the country!

Just like Qi Heng said, can this thing be changed to the richest man?

These words, now that I think about it, can be regarded as a slap in the face.

Qi Heng understood, he had always understood, that he didn't want to be involved in their affairs at all.

When he said these words, he was telling himself that even if you are doing business, you will not be taken seriously by me.

To use you is to give you opportunities.

Such a person is still in Huanggang, but he still doesn't look down on this Huanggang.

Especially in the last words, water vapor is important, pressure is also critical, and the boat and car made with these principles are a powerful weapon of the country.

But compared with these, a change of thinking is even more commendable.

5,000 catties of grain per mu!

Thinking of this, Shen Wansan felt that his whole body had no strength, as if he had collapsed.

.................

On the way home.

Qi Heng thought of what he had just said to Shen Wansan, and couldn't help but shake his head and smile.

In order to retain this talent, he has gone to great lengths.

He even did not hesitate to take out the principle of the steam engine centuries later.

Although there are still great difficulties and ways to go before it can be realized, after all, this is the cornerstone of the first industrial revolution, but the principle is indeed like this, and he is not nonsense.

Moreover, heating is indeed something that can be achieved now, as long as the production of iron catches up, it can be implemented concretely.

Back to Fuchu.

Qi Heng will still be picked up at Ma Xiuying's house.

On the way back to his house, Qi Heng still looked at Qi Heng in his arms and said, "Brother, what happened to you?" Why are you so happy? ”

Qi Heng was stunned: "Is there one?" ”

Still nodded earnestly.

After thinking about it, Qi Heng said: "My brother just went to teach a rebellious person a lesson. ”

Still immediately said: "Is it the uncle who went out with my brother before?" ”

Qi Heng smiled and pinched his nose, and said, "I'm still really smart, but I still can't call him uncle, I still have to call him brother." ”

"But... They are all so old, how can they still call them brothers? ”

Listening to the words, Qi Heng didn't know how to answer, and for a while he regretted calling him brother at that time.

The subordinates around him are not young, and it is natural and reasonable to still call him uncle, but his own seniority has fallen in vain.

...................

Early the next morning.

Qi Heng got up and pushed open the door after washing, saw Shen Wansan standing in the courtyard, and after thinking about it, he remembered what made him come over early in the morning last night.

Came to him and said, "Think it through?" ”

Shen Wansan nodded obediently and said, "Think clearly, adults give face, Wansan must know how to lift." ”

Qi Heng smiled and said, "Then come with me, eat something, and take you to meet people in a while." ”

After eating breakfast in Ma Xiuying's courtyard, Qi Heng took Shen Wansan out of the door.

As he walked, Qi Heng asked, "Since you followed me, what about your brothers?" ”

Shen Wansan replied: "I explained to them, except for a few who want to continue to follow me, I have arranged everything else, if you want to stay in Huanggang, you will continue to do the things that snared the people, and if you want to go back to your hometown, I will also divide their part of the silver into two cents." ”

Qi Heng was about to say something when Han Qin walked over to him.

Glancing at Shen Wansan, who was beside Qi Heng, Han Qin handed over the documents in his hand to Qi Heng and said, "My lord, I have inquired about everything you asked me to inquire about, and I have sorted out a list of personnel and relationships on it." ”
