Since Feng Wenwen joined the laboratory, Lin Yan has taken her with him wherever he goes.

Shi Zhi quipped: "Is this a companion?" I can't see us old people. ”

"Haha. That is, who doesn't like Wenwen, you say? ”

Seeing that Feng Wenwen's expression had not changed, Shi Zhi pursed his lips, "It's good if you like it." ”

"I love it. Xia Jie is also very good, you have a good eye for picking people. ”

Xia Jie is the person selected by Shi Zhi, and he is not very old, seven years old. Lively and bold, with a flexible brain, and Shi Zhi has the same smell.

With them on board, everyone feels a lot more relaxed. Usually there are people to help with the work, and there is no need for just a few people to help back and forth.

There are not many words in the literature, and he always follows Lin Yan silently, and only takes the initiative to speak when he mentions her or encounters her puzzled.

It is indeed rare for such a character to appear in a little girl.

Xia Jie is completely different, lively and active, self-cooked, and can get along with anyone. Lin Yan also likes him a lot.

The rest of the people are also different, but they all have one thing in common: they are very studious and curious about everything.

Today, Lin Yan took Feng Wenwen to prepare to go boating, because Feng Wenwen asked her why the water flows from north to south.

Actually, the answer is very simple, it's just that the terrain in the north is high, and the water flows to the lower ground. But Feng Wenwen had never been on a boat, and Lin Yan wanted her to observe it in person.

The boat has been docked by the river, Yun Qing sent two people to watch, someone wants to take the boat, they will help row together.

Today is Shi Qiang and Bai Song on duty by the river, and they are all very happy to see Lin Yan.

"Why are you here?" Bai Song looked at the little girl beside Lin Yan, "This is Fengwenwen, you stand together and look at it differently, your temperament is similar, no wonder you can choose her." ”

Shi Qiang also said: "That's it, they are all smart dolls, so they can play together." ”

Lin Yan smiled, "This is Fengwenwen, she is very smart, we don't play together, we do research together." We wanted to take a boat. ”

"No problem, get on board." Bai Song hurriedly said, "With me and Shi Qiang here, you two can rest assured, rowing is steady and fast, you will definitely like it." ”

Several people got on the boat, Lin Yan and Feng Wenwen sat in a row, one left and one right, Shi Qiang rowed in front of him, and Bai Song guarded behind.

More than ten days passed, and every day people came to take the boat curiously, and the water was not as dangerous as imagined, and everyone gradually felt relieved.

Looking at the calm river, Lin Yan said to Fengwen: "This section of the river is deep and suitable for boating. You can seriously feel the power of water. Consider what I told you yesterday about the velocity, gravity and buoyancy of the water, and we now have four people on board, and the total weight is about 400 pounds, and calculate how much area we would have to have if we were standing on a plank. ”

Bai Song and Shi Qiang kept pricking up their ears to listen, originally thinking that they could say a few words to them, but after listening to Lin Yan, they were silent.

It's too advanced for them to understand at all.

Bai Song was thinking, no wonder Lin Yan was able to make the boat, it turned out that there was such a profound knowledge here. She didn't just come on a boat with her style, but to explore something more esoteric.

Shi Qiang seemed to be concentrating on rowing, but his heart was turbulent. That's the question that smart dolls think, it's completely different from what they see.

They understood every word of what the two were talking about, but they didn't know what it meant.

Feng Wenwen nodded, "Is it calculated according to the theoretical value, you also said that some constants such as gravitational acceleration have not been verified, and the accuracy will be further checked when the conditions allow in the future." If the calculation is based on theory, the calculated results may be biased. ”

"Ignore the variables of gravitational acceleration, calculate it first, and we'll check it further when we go back. After you calculate the area of the plank, we will test it ourselves to see if it can withstand the weight of 400 catties. ”

Feng Wenwen nodded, completely mentally calculated, and soon reported a number, she said: "This area also ignores the weight of the plank, and we have to adjust it according to the weight of the plank when we test." ”

Lin Yan nodded with satisfaction, "Not bad." It will be revised when it comes to specific trials. When the test is completed, we will make a model of the big ship together. ”

After these days of hard work, her big ship has been designed, and she first needs to make a model that can carry people out and verify the feasibility.

Feng Wenwen's eyes lit up and he nodded heavily. It is really right to follow Lin Yan, you can get in touch with the latest things. Being able to build a ship with her is something Feng Wenwen wanted to do before.

The two sat on the boat for more than half an hour, watching Lin Yan look at the other side of the river, Feng Wenwen's eyes flashed, and it was also the place she wanted to set foot in.

When they got off the boat and left, Shi Qiang and Bai Song glanced at each other, and they both saw the same doubts and surprises in each other's eyes.

"Say, what's going on in their heads?" Shi Qiang touched his head, very confused, "Do you understand what they said just now?" ”

Bai Song shook his head, "Those are very profound things, my sister should understand." If you want to know, I'll go back and ask Bai Chen. ”

Shi Qiang waved his hand, "Forget it, it's hard to understand when you hear it, and I can't figure it out." I suddenly felt that the gap between us and others was really not ordinarily big. ”

"It's just that Bai Chen writes and draws things at home, and I can't understand them. Let's not think about that, just train well and protect them. ”

"Also, Heitu often says that we are not smart enough, but we must have a strong body and escort them in the future. Let's leave the matter of using your brains to Lin Yan and them. ”

The two of them were distressed for a moment and then left behind, everyone has their own mission, and there is no need to force it.

When they had dinner together that night, Hua Hong said: "The official courtyard has issued a notice, and the plan for the commercial street is a street with a width of 15 meters, a length of 1,000 meters, and the houses on both sides are built facing the street, and the courtyard is behind. The smallest yard is a room with a backyard, and the foundation costs 1 dime, and the bigger it is, the more expensive it is. ”

Jin Zai also said: "This is just the money to buy the foundation, and you have to pay for the house yourself." The tribunal was only responsible for repairing the road, the street had been paved, and the foundations on both sides had been painted. Our family runs a restaurant, and one room can make do with enough. Just set up a table in the front room and build a kitchen in the back yard. ”

"No, a room is too small to use. If you want to buy, choose a larger one, and you need at least three rooms. "Lin Yan didn't want to buy a small place, it was too crowded.

Speaking of which, both the bonus and the golden boy disagreed, the foundation can be afforded, but it is also a lot of money to build a house.

Lin Yan said: "Tomorrow we will go to the official office and buy the foundation first." ”

That night, Lin Yan moved out of his piggy jar and counted it, and he had saved twelve yuan and six dimes, which was completely enough to build a house.

After looking at it, the bonus agreed to buy the foundation.
