Yu Ren patted the dust off his body and stood up from the ground. said, "It's still second-class, it's a pity, it's a pity." ”

Looking at Huang Han again, he was still standing there straight, staring blankly at the chair surface that remained in place and the stone tied to it.

Yu Ren walked up and carefully inspected the chair. The joints between the four legs of the chair and the chair surface are all broken, and they are broken relatively neatly. This shows that the thrust of these four rockets is still not small. If the chair continues, Yu Ren believes that this stone will definitely be pushed up by these four rockets. I just don't know how high I can push.

"Don't be discouraged, this is not a failure. The main thing is that the chair is not strong enough. Next time I make a stronger chair, it should be done. Perhaps, we can try to use iron to hold the chair surface firmly. Yu Ren untied the stone from the chair, and then took the chair to Huang Han.

He said as he handed the fallen chair surface into Huang Han's hands.

Huang Han took the chair in his hand and carefully looked at the sections of the four corners.

At this time, Huang Wu also walked over. "Blame me. I got this chair from home. The fourth brother told me to find the strongest chair. I thought to myself, since it's so solid to sit on the floor, it must be fine. But I didn't expect it to break so easily. ”

Yu Ren gently patted Huang Wu's shoulder. "Little brother. You don't want to think about it either. These four rockets with such a large thrust suddenly exert force upwards at the same time. How big is this upward momentum, how can the chair be withstood if it is not firm.

However, there is one thing I don't understand. What the hell are you trying to do with this? Are you really planning to ride this thing and fly to 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 the sky can actually go up. As long as we keep working hard, maybe one day, we can rely on this thing to send us to the moon.

There will be no wars on the moon, and there will be no tax supervisors beating people or government oppression. When the time comes, we can take my father and my mother to live on the moon. How nice that would be! We can grow rice on it, we can also grow vegetables, we can raise pigs. How nice it would be that there was no one to fight for the land, and that we didn't have to pay taxes and grain. ”

Yu Ren let out a long sigh. He didn't laugh at the ridiculous ideas of the half-grown kids in front of him, everyone had a dream in his heart, and no matter how ridiculous that dream was, it should be respected. Yu Ren admired their courage to explore the unknown, and it also made him realize for the first time that we in China, since ancient times, have never lacked people who have the courage to explore science. The ancients in China were not all stubborn, but only those who thought about it were stubborn. They have their own way of understanding and exploring nature. This kind of exploration comes from their pursuit of dreams.

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

"Yes, of course. When we didn't have any money before, the fourth brother still took all of us to try it out in various ways. Now that I have these fifty taels of silver, of course I have to do more. Huang Wu said firmly. I'm going to go to the moon and open a 50-acre paddy field! ”

Yu Ren didn't smile at Huang Wu's whimsical idea, he looked at Huang Han. Huang Han didn't speak, but nodded firmly.

"Can I do it with you?" Yu Ren asked. He was getting more and more curious, and he really wanted to see what these kids could make.

"You? ......" Huang Wu glanced at Huang Han and did not speak.

"Absolutely. Has Yu Gongzi made this kind of thing before? Huang Han was very happy to hear that Yu Ren was also going to participate. Although he has known Yu Ren for less than half an hour. However, from the fact that Yu Ren discussed with him the question of how to land safely after sending people to heaven, he concluded; The person in front of them will play a decisive role in the success of their future plans.

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

"Let's go now." Huang Han keenly felt that Yu Ren would bring major reforms to his plan, and perhaps help him break through the bottlenecks that he had been unable to break through these days. Therefore, he couldn't wait to invite Yu Ren to go with them immediately for a new experiment.

Xu Shichang, who lost fifty taels of silver from Bai Huahua, actually didn't go far, he clearly watched the scene of Huang Han's ignition test shot 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 about flying to the moon.

He was more interested in what Huang Wu said, about opening up wasteland and building paddy fields on the moon. Their Xu family is a big family in the south of the Yangtze River, but they have little power in Hangzhou. Because their family moved from Songjiang Mansion to Hangzhou from his father's generation, they are considered outsiders.

So, although their family is rich, they have very little land. There are only dozens of acres of thin fields left by the ancestors of Songjiang Mansion, but in Hangzhou, their family does not even have an acre of land. It's not that his father doesn't want to buy land. It's because they have no relationship in Hangzhou officialdom and can't buy land at all.

In Xu Shichang's heart, he has always had such a dream, he hopes that his family can also have thousands of acres of paddy fields like other large families. Because in his opinion, no matter how much silver there is, there will always be a time when it will be spent, not to mention, this thing will be stolen and robbed; But the field is different, once it is yours, it will always be yours. Others can't steal if they want to, and they can't rob it.

Of course, this idea of his was also greatly influenced by his father.

In order to realize the ideal of going to the moon to open the ground, Xu Fatzi decided to follow these people.

Huang Han and Huang Wu did not take Yu Ren to their house, but took Yu Ren and Cao An to the outside of the city. After rounding the West Lake, they climbed a relatively high mountain. Although it is not far from the city of Hangzhou, it is not suitable for growing tea because it is a mountainous area, so there are very few residents on the mountain.

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

Huang Han pointed to the stone house and said, "It's here." There it is. ”

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. Looks like this should be their testing ground. Yu Ren thought.

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

The house is small, there are only two rooms, one of which has a window.

"This house was borrowed from a collapsed stone house by our brothers, and then rebuilt." Huang Wudao.

Yu Ren raised his eyes and looked around. There was a room with all sorts of strange woodwork, some long like a dragon, some like a running tiger and leopard, which looked even more like a cloth on the outside. There were carpenter's tools piled up next to it. These things, which looked a lot like the carousels in the amusement parks of later generations, made Yu Ren wonder what they were used for.

In another room, there are various fireworks made and unfinished, and some scattered outer cylinders. Yu Ren noticed that although the format of these fireworks is slightly different, they are basically straight cylinders, which are basically the same as the four that Huang Han made 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 was able to make these things, because he knew that our ancients had long used gunpowder in warfare. To his surprise, he was at the foot of Wu Mountain and heard two explosions. That is, these rockets are no longer ignited at one time, but propelled in two sections. They are already very much the prototype of modern rockets.

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

"These! These are dragon bodies that one of my brothers helped me make. Our original plan was to imitate the fire dragon made by the predecessor of the ten thousand households during the Hongwu period of our dynasty. That's why I asked one of my best brothers to make these things for me. Their family worked as carpenters.

However, I found out later. This kind of thing is really not very stable for people to sit on, and it is also very difficult to launch. So I switched to chairs, and I left them here. ”

Yu Ren carefully observed the wooden products. He found that these things were actually very refined 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 for the time being.

"Have you ever tried it successfully?" Yu Ren asked.
