The next day, Lin Yan walked on the road and everyone she met greeted her happily.

She found that everyone was in a good mood. This is because the mining team is back, bringing hope.

When she arrived at the laboratory, she found that Heitu and many people were gathered in the courtyard, looking around the rack car.

Mao Mu was telling them about the structure of the cart, pulling the cart around the yard as he spoke.

Heitu and the others were so excited that with a frame car, as long as the road was repaired, they could bring back as many things as they wanted.

The rack car is now a rarity in Sun City, there are only two in total, the earliest one is in the laboratory, and the other is in the public office.

If you need a car, you can rent it at the official office.

Huo Qiang said in a strong voice: "This car is so easy to use, minister, we have to get a few for our military department." ”

Hei Tu nodded, "I'll apply later, the ore we brought back should be enough to make a few rack cars." ”

"It must be enough, you brought back more than 2,000 catties of ore, and it is enough to make more than a dozen rack cars." Mao Mu followed. He looked at the black soil happily, "You are all great heroes, and good things should be used for you first." ”

"You kid really talk." Huo Qiang laughed, "However, who made this frame car, and the person who can make it has the greatest credit." ”

"It's just that I've never thought of something so delicate. I didn't know that it could be done like this, which was convenient for everyone. Lan Xing was also there, praising him: "It's so smart to be able to come up with it and make real things." ”

The others nodded their heads, but this is not it, they never thought of it, and there is such a magical thing as a frame car, if you don't see the real thing with your own eyes, you can't believe it when you hear others.

Mao Mu said loudly: "The person who came up with it was Lin Yan, but it was done under the leadership of Shi Zhi and several people together." ”

"You lab people are amazing." Lan Xing really thinks so, the ten babies who followed Lin Yan's class at the beginning are all smart, and now in Sun City, there are their shadows everywhere.

Behind the emergence of every novelty, there is their participation.

Lan Xing was very sorry in his heart, why didn't he pestered Lin Yan with a dead face in the first place, and followed him to class. Although he is a few years older, he has enough brains, and he really can't do it, so he can help with the coolies.

It's just that now I can only think about it, I've missed it, what's the use of regretting it.

Lin Yan walked in, raised a smile and said, "The frame car is the credit of many people, not one person can make it. You are one of them. We wouldn't have been able to do it without you taking the risk of bringing back the ore. ”

Hearing Lin Yan say this, a group of people suddenly felt honored, and it turned out that they were also involved.

Hei Tule said: "Don't be modest. Lin Yan, let's just take a look at the rack car, you are busy, leave us alone. ”

Lin Yan smiled and nodded, indicating that he understood, and let them take care of themselves.

When the people had seen enough, they gradually dispersed, and the black soil came to Lin Yan's house.

After looking at it, it was much cleaner than before, and there was no unpleasant smell. Heitu smiled: "Your house is a lot cleaner. ”

Lin Yan also remembered that when the black soil came, he was doing a papermaking test, and the whole laboratory was filled with a strange smell. She smiled and said, "You still remember." At that time, I was in a hurry, and I was doing experiments like this, and it was never too clean. There's a stool over there, you sit. ”

Hei Tu was not polite, sat down, saw the notebook on the table and asked, "What is written on it?" ”

"It's all a record of test data. Do you have something to do with me? ”

Heitu is a busy person, and if he can take the initiative to find the door, there must be something. Lin Yan didn't think that he just came to sit casually.

"You're right, I'm looking for you for something." Hei Tu directly admitted, "You said that you would build an iron-making plant on the side of the mine and send people to work there, when are you going to start construction?" ”

Lin Yan didn't expect him to come for this, "I don't care if I say anything about this matter, you just need to discuss it with Ah Lan." However, I don't think it's time yet, so I'll have to wait two or three years. ”

Hei Tu said: "I wasn't in a hurry, but after seeing the rack car today, I think the demand for iron will be greater in the future." If the ironworks were built earlier, we would have needed as much iron as we needed. Relying on us to deliver such a trip is not enough in a short time. ”

"No matter what time it is, it's not enough. The rack car is just the beginning. Lin Yan wants to do too many things, and the demand for iron is unlimited, "Now the priority is to meet people's daily needs." From next year, we will invest a lot of iron to build various things. ”

Seeing that Lin Yan had already planned, Hei Tu's mind moved, "What are you going to do?" ”

Lin Yan took out the model of the ship he had made and introduced it to Heitu, "This is a boat, which can sail in the water." We live on the banks of the Sun River, and there should be other people along the shore. Once I've built the boat, we'll be able to set off together along the River of the Sun in search of other humans, and more resources. ”

Exploring this world has always been Lin Yan's goal. She has long been eyeing the Sun River, such a wide river, the water is also deep, it is not difficult to sail.

Walking along the river is faster and safer than on land. As long as their ship is strong enough, nothing is a dream.

Hei Tu looked at the model of the boat blankly, and said after a while: "This boat can really carry people on water and won't sink?" ”

"No, it won't. Water is buoyant and will not sink as long as the boat is well designed. ”

Hei Tu really wanted to pry open Lin Yan's brain to see what else was in it, she could come up with such an unbelievable thing.

Lin Yan took a basin of water and put the model boat on it.

Black Earth's eyes widened, "It can really float." ”

"Of course I can, otherwise I'd do this. You take a plank, and as long as it's big enough, it can float in the water. ”

Hei Tu touched his head, "It's not like I've never thought about it that way, I'm too surprised to see it for the first time." When your ship is ready, I must stand up and feel it myself. ”

"That's for sure. Speaking of which, there is something for you to do. ”

Lin Yan took a piece of paper with her plan written on it. Since you want to build a ship, you can't help but know the nature of water.

She had long discovered that the people of the Sun Tribe were very afraid of water, which was engraved in their bones. Except for fetching water, I rarely go to the water's edge.

After inquiring, I learned that this is passed down from generation to generation, and there have been ancestors who have seen the scene of a monstrous flood, which has submerged countless people, leaving an unforgettable impression that has been passed down from generation to generation.

Heitu took the paper and read it carefully, and asked uncertainly, "Do you really want to learn to swim?" ”

Lin Yan nodded, "After the boat is built, we must learn to swim if we are to be active on the water." In case of an accident, you can save yourself. Dig a big puddle next to the drinking canal, and you ask the people in the military department to start training and make swimming a must-learn. ”

Hei Tu looked at Lin Yan's insistence, and only felt that the paper in his hand was too heavy.
