Yu Ren patted the dust on his body and stood up from the ground. He said, "It's still a level two. It's a pity, it's a pity."

Looking at Huang Han again, he was still standing there, staring blankly at the chair surface left in place and the stones tied to it.

Yu Ren walked up and carefully inspected the chair surface. The joints between the four legs of the chair and the seat surface were all broken, and the breaks were relatively clean. This shows that the thrust of these four rockets is not small. If the chair surface

Constantly, Yu Ren believed that the stone would be pushed up by these four rockets. But he didn't know how high it could be pushed up.

"Don't be discouraged. It can't be considered a failure this time. The main reason is that the chair is not strong enough. Next time, we should make a stronger chair. Maybe we can try to use iron to fix the chair surface firmly." Yu Ren said to Shi

He untied the chair from the chair and came to Huang Han with the chair.

As he spoke, he handed the fallen chair surface into Huang Han's hands.

Huang Han took the chair in his hands and carefully looked at the four corners of the section.

At this time, Huang Wu also came over. "It's my fault. I brought this chair from home. My fourth brother told me to find the strongest chair. I thought at the time, since it's very stable to sit on,

, then there must be no problem. But I didn’t expect it to break so easily.”

Yu Ren gently patted Huang Wu's shoulder. "Little brother, don't even think about it. These four rockets with such huge thrust suddenly exerted upward force at the same time. How big is the upward momentum? How can the chair not be strong to withstand it?"

However, there is one thing I don’t understand very much. What do you want to do with this thing? Do you really plan to get on this thing and fly into the sky one day?”

Huang Wu glanced at Huang Han, who was still in a daze, and then whispered to Yu Ren, "My fourth brother told us that we can actually go up to the sky. As long as we keep working hard, maybe one day we can rely on this

Something to send us to the moon.

There will definitely be no wars on the moon, and there will be no tax supervisors beating people, or government oppression. At that time, we can also bring my father and my mother to live on the moon. That would be great! We

We can grow rice, vegetables, and raise pigs on it. No one will compete with us for the land, and we don’t have to pay taxes on food. That would be great.”

Yu Ren let out a long sigh. He did not laugh at the ridiculous ideas of the half-grown children in front of him. Everyone has a dream in his heart. No matter how absurd the dream is, it should be respected. For their courage to explore

Yu Ren admired the unknown spirit, and it also made him realize for the first time: Our China, from ancient times to the present, has never lacked people who have the courage to explore science. Not all ancient Chinese people were born, there are only those who can only read things.

They are old stubborn people. They have their own way of understanding nature and exploring nature. This exploration comes from their pursuit of dreams.

"Then, will you try again in the future?" Yu Ren asked softly.

"Yes, of course. When we had no money before, the fourth brother took all of us and tried every means to try it out. Now that we have these fifty taels of silver, of course we have to do it even more." Huang Wu said firmly.

He said, "I also plan to go to the moon to open a fifty-acre paddy field!"

Yu Ren did not laugh at Huang Wu's fantastic idea. He looked at Huang Han. Huang Han did not speak, but nodded firmly.

"Can I do it with you?" Yu Ren asked. He became more and more curious and really wanted to see what kind of things these children could make.

"You?..." Huang Wu glanced at Huang Han but said nothing.

"Of course. Has Mr. Yu done this kind of thing before?" Huang Han was very happy to hear that Yu Ren was also going to participate. Although he had known Yu Ren for less than half an hour, Yu Ren had just discussed it with him.

He concluded that the person in front of him would play a decisive role in the success of their future plans.

At this time, the onlookers saw that there was no more excitement to see, so they dispersed one by one.

"Let's leave now." Huang Han felt keenly that Yu Ren would bring major reforms to his plan, which might help him break through the bottleneck that he had been unable to break through these days. Therefore, he couldn't wait to invite Yu Ren to meet him right away.

They go together to conduct a new experiment.

Xu Shichang, who lost fifty taels of silver in vain, actually did not go far. He clearly watched the scene of Huang Han lighting the fire and testing the fire not far away. Although he lost fifty taels in vain, he did not regret it.

Because he was also very interested in what Huang Wu and Yu Ren told him about flying to the moon.

He was more interested in what Huang Wu said about clearing wasteland and building paddy fields on the moon. The Xu family was considered a big family in Jiangnan, but they had little influence in Hangzhou. This was because their family moved from Songjiang Prefecture in his father's generation.

Those who come to Hangzhou are considered outsiders.

Therefore, although their family is very rich, they have very little land. They only have dozens of acres of thin farmland left by their ancestors in Songjiang Prefecture, but in Hangzhou, their family does not even have an acre of land. This is not because his father does not want to buy land.

.It’s because they have no connections in Hangzhou’s officialdom and can’t buy land at all.

Xu Shichang has always had such a dream in his heart. He hopes that his family can own thousands of acres of paddy fields like other wealthy families. Because he believes that no matter how much money there is, it will eventually be spent. What’s more, this

Things will still be stolen and robbed; but the field is different. Once it is yours, it will always be yours. Others cannot steal it or rob it if they want to.

Of course, his thinking was also greatly influenced by his father.

In order to realize his dream of going to the moon to open up land, Fatty Xu decided to follow these people.

Huang Han and Huang Wu did not take Yu Ren to their home, but took Yu Ren and Cao An out of the city. After bypassing the West Lake, they climbed up a relatively high mountain. Although it is not far from the city of Hangzhou

, but because this place is a mountainous area and not suitable for growing tea, there are very few residents on the mountain.

It took them more than half an hour to climb to the mountainside. Yu Ren was about to ask them how far they were, when he saw a small stone house appearing in front of them.

Huang Han pointed to the stone house and said, "We're here. It's right there."

Several people approached the stone house. Yu Ren saw that there was an open space outside the stone house, and there were many traces of explosions and fires on the ground. It seemed that this should be their testing ground. Yu Ren thought.

While Yu Ren was facing the open space outside the house, imagining how such a young man could conduct such a dangerous experiment, Huang Han had already opened the door of the stone house. Several people walked into the house.

The house is very small, with only two rooms, one of which has a window.

"This house was built by us brothers who borrowed a collapsed stone house from here and then rebuilt it," Huang Wudao said.

Yu Ren raised his eyes and looked around. There was a room filled with various strange wooden products. Some were made like a long dragon, and some were made like a running tiger and leopard. Because they were covered with cloth, they would

It looks even more similar. There are also some carpenter's tools piled next to it. These things look very much like the merry-go-rounds in amusement parks in later generations, and Yu Ren can't figure out their purpose.

In another room, there are piles of various made or unmade fireworks and some scattered outer tubes. Yu Ren noticed that although these fireworks have slightly different formats, they are generally straight-cylindrical.

They are basically the same as the four rockets Huang Han made just now at the foot of Wu Mountain. These should be the rockets made by Huang Han, Yu Ren thought.

He was not surprised that Huang Han could make these things, because he knew that our ancients had long used gunpowder in warfare. What surprised him was that just now he heard two explosions at the foot of Wu Mountain. In other words, these

Rockets are no longer ignited in one stage, but propelled in two stages. They are already the prototype of modern rockets.

"What are those things used for?" Yu Ren asked, pointing to the wooden products that looked like beasts placed in the corner.

"These! These are the dragon bodies that one of my brothers made for me. Our original plan was to imitate the fire dragon made by my senior Wanhu during the Hongwu period. So I asked one of my best brothers to

Helped me make these things. Their family is a carpenter.

However, I later discovered that this style of thing was not very stable for people to sit on, and it was also difficult to move. So I later used chairs instead, and the finished ones were left here.

"

Yu Ren observed these wooden products carefully. He found that these things were very finely made and very strong. Just from the workmanship of these things, you can know that this carpenter's craftsmanship must not be simple.

Of course, these are not his main concerns yet.
