"This ...... This ...... "Chen Moru's aura is stronger than that of Huan Zilou, and Xin Daqiang instantly fell into an abyss and hell. Under the two wars, he already understood a truth, if he could not give a reasonable explanation, I am afraid that he would suffer extremely terrible consequences. However, he really didn't know how to answer, and if he could tell the truth and put all the problems on his son, he would not have to worry about weaving lies. But no matter how smart his son is, he is only four years old, and he can withstand such terrible pressure. Or is it that the son can solve the doubts of this ghostly old man Chen very well?

Xin Yu was also stunned by the sudden coercion, and painfully recognized a pessimistic fact: The sorrow of the grassroots in this world is not only that they can't eat, nor that they can't protect their own property safety, but that even their lives are like mustard, at the kneading of the strong. Although he had been mentally prepared, when such an encounter reality came to him, he realized that even Chen Moru, who was a wealthy family in a remote place in Puli Town, was not a big man in the mainland or even Haizhou, and looked at them like ants.

Xin Yu knows that he doesn't know why Chen Moru had such a misunderstanding, because of the asymmetry of information. There is only one continent in this world or the planet where he is located, and there are countless large and small oceans outside the continent, but the largest is only the size of two Haizhou. The larger ones have no other products except the natives, so the demand for sea ships in this world is not strong at all. And the model of the lucky ship that Xin Yu took out, although it is not high-tech, but it also surpasses other ships in this world, which is naturally very abrupt. Coupled with the Chen family's own factors and the background of the Xin family's grass people, Chen Moru naturally thought that someone wanted to use the Xin family's father and son to get close to the Chen family.

Looking at his father's hesitant appearance, afraid that Chen Moru would be free to prove that they had a ghost in their hearts, Xin Yu had no choice but to bite the bullet and say: "Master Chen, although I don't know why you misunderstood our father and son, we really didn't receive anyone's guidance and instructions. As for the ship model, it was indeed made by me independently. ”

Chen Moru didn't believe Xin Yu's defense: "Oh, then how do you explain that you, a four-year-old doll, don't even know the words, but make such a ...... What about a reasonable boat?"

Perhaps facing the great pressure of survival or destruction, Xin Yu's thinking suddenly became very clear, and he asked rhetorically without thinking: "Do you need to be literate to make a boat?"

Chen Moru sneered, and then pointed to the original two ship models with some disdain: "You really don't need to be literate to make a boat, but it is said that you have never even been to the beach, how can you swear to Eun Zilou that this kind of small boat can definitely be enlarged into a sea boat?"

Xin Yu admitted that he owed it, because he wanted to change his life situation, he boasted to Huan Zilou about Haikou and caused such a misunderstanding. But he is even more annoyed by this kind of person who always wants to completely control the development of things, and cannot tolerate the slightest doubt and uncertainty, let alone the slightest disobedience from others.

However, the person had to bow his head under the low eaves, and he said honestly: "So that Master Chen knows that the boy is born precocious and has a strong interest in all things in nature, and through the observation of all things in nature in the past two years, I have found that there are basic laws in everything in this world." And these laws can be applied to ships, and of course, to other aspects. Take ship design as an example, it is mainly applied to the mechanical principles of many laws, including liquid buoyancy, object shear stress, gravity principle, fluid mechanics and many other mechanical knowledge. In ship design, the first thing is to use liquid buoyancy to design the load and building facilities, use the shear stress of objects to design the structure of the ship, use the gravity principle to calculate the center of gravity, and use fluid mechanics to design the hull shape and sail ......"

The more Xin Yu spoke, the more excited he became, it didn't matter if he was right or not, anyway, it was impossible for the indigenous master in front of him to hear something wrong, it didn't matter if others could understand it or not, he didn't need it and didn't really want them to understand. Balabala said so much knowledge of his previous life, and at first he relieved his doubts to save his life, but as he spoke, he felt as comfortable as God sending an oracle to an ignorant mortal, and Uncle Hongjun preaching to the grass and trees and stubborn stones. And in the more than four years since he was reincarnated, although he has enjoyed the warmth of his family, he has no one who can communicate with him, and now he is talking like a train, and the loneliness buried in his heart has been vented, so he has ignored the pressure Chen Moru gave him, and he was so happy that he couldn't get out of the car.

"Okay, okay, I don't know if what you're saying is true, I need to prove it. Chen Moru was annoyed by the little physics teacher's "teaching", and hurriedly interrupted.

Xin Yu, who was interrupted, was a little unhappy, and asked boldly: "Prove?

Chen Moru was bombarded indiscriminately by a four-year-old child, and he also felt very faceless, this will finally regain the initiative, and the corners of his mouth unconsciously curled: "That's your business, isn't it?"

Xin Yu feels that he is messy in the wind, and people have clearly bullied you, can you choose no? Xin Yu has been poisoned by the obscenity of his previous life for many years, and naturally he does not have the courage and toughness of Liu Hulan, so he chooses to be a "junjie" who knows the current affairs.

But in his previous life, there was no need for employment, Xin Yu only wanted to understand scientific knowledge, and he really wanted him to list Bernoulli's equations, sorry for the tutor, he didn't work hard back then...... If he really wants to prove that knowledge, he can only rely on experiments.

Two iron balls hit the ground at the same time, or a ruler weight balance experiment, or a negative pressure experiment on paper pieces? No matter what, do it, the more strange it is, the more profound it is. You are an indigenous old wealthy, and the master makes you unaware.

The experiment was successful, but the results were ...... Appalling.

"Little doll, I've seen all these tricks you've done, what can you prove?" Chen Moru frowned.

"Hmph, what kind of big head of garlic, have you really seen it? Even if you have seen it, do you understand the truth?" Xin Yu was scarred in his heart, but the words he said were able to bend and stretch: "Master Chen, I know that you have seen these experiments, but the kid has realized the basic truth from them, and I will draw it for you." ”

As he spoke, he walked unceremoniously to the table, spread out a piece of snow-white rattan pulp paper, and then thought that the brush was inconvenient, so he directly picked up the ink block and used the sharp corner as the tip of the pen, and drew the force analysis diagram of the balance of the ruler hammer. While drawing, he explained the power represented by various lines, and finally fooled Chen Moru into a cloud and mountain fog, and then summed up without shame: "In short, through this phenomenon, I realized the calculation method of the center of gravity, so that I can design the structure of the ship, so that the center of gravity is kept below the water surface to ensure that it will not be blown down by the wind and waves." ”

This time it was Chen Moru's turn to scarlet belly, but he used his mouth directly: "Stinky boy, you only explained the simple truth of the center of gravity, and nothing else?"

"Uh, Master Chen, blow the paper...... It shows that when the wind blows, there is not only thrust, but also traction under negative pressure, which can be used to design the shape of the sail. The experiment of objects of different weights falling to the ground at the same time shows that there is a downward gravity in our world, and proves the relationship between force and velocity. Proving gravity naturally proves that there is buoyancy, huh?" Xin Yu blinked, and then slapped his leg loyally and said, "Okay, I'll do another buoyancy measurement experiment." ”

The previous experiments were done on the spot using local materials. But the buoyancy experiment was a bit troublesome, and in the end, Chen Moru's daughter Chen Han also took the initiative to bring the things Xin Yu said he wanted: a porcelain bowl, two large and small basins, a large bucket of water, and a scale.

Let Daddy hang the small basin with a rope, put the large basin directly below the small basin, and then Xin Yu scooped water from the wooden bucket to fill the small basin, and then gently put the porcelain bowl into the small basin. After the bowl floats, weigh the water that overflows from the small basin and the weight of the bowl, and the experiment is over.

"Master Chen, you see, from the buoyancy experiment, we can conclude that buoyancy is equal to the gravity of the porcelain bowl and the gravity of the porcelain bowl to drain the water. Although he got up early in the morning, it was already noon after a long time of work, and Xin Yu was already hungry, so some of them no longer sold off, and directly explained: "The results of this experiment can be used to design the loading capacity of the ship and ensure the limit of the ship's loading." Because of the conditions, I can only do these few experiments, but the other phenomena I have observed, and the principles can also be generalized, all of which can be applied to ship design, Mr. Chen, do you think we can prove that we are fine?"

Chen Moru didn't know if he agreed with Xin Yu's explanation, so he didn't answer directly: "You were hired." ”

Xin Yu didn't care whether the other party understood the connection between the principle and the application, and he was not Chen Moru's teacher, anyway, the content of the transaction was not a scientific principle. Of course, he didn't care if he was trusted or not, anyway, he just had to build a ship that could sail far, and the Chen family only needed to pay for it.

The rest of the details naturally don't need to be taken care of. After eating a lunch provided by the Chen Mansion, he talked to Ding Shisheng, the chief steward of the Chen Mansion, about the details of the transaction.

Objectively speaking, although Ding Shisheng does not deal with Huan Zilou and speaks a little mean, he is not a villain. Even when negotiating with a four-year-old child, there was no deception, and the face of the square Chinese character was full of sincerity.

"I need a sum of money to settle in, and of course, I would prefer to have my own residence in the Chen Mansion so that it will be easier for me to work. Xin Yu learned from the negotiator in the TV series in his previous life, and put forward the first condition very pretendically, completely unaware that this expression with a childish face was too funny.

"Living in the Chen Mansion, you are not qualified yet. Ding Shisheng decisively refused, but he was also a little hesitant, and the negotiations did not go well at the beginning, which made him frown a little.

"I think it would be better to build a settlement at the foot of the hill by the sea, for for for for some time to come I will need at least twenty boatmen and carpenters to work with me. If you don't arrange a place to live nearby, you will be delayed on the way back, which will affect the completion time, and it is easy to leak secrets. Xin Yu retorted unequivocally. He didn't really think about the Chen family, but Chen Moru asked to build a boat by the sea in the courtyard of the Chen Mansion, which made him fed up with the feeling that his life was threatened, so he retreated to let the family concentrate on the seaside, so that he could run away from the sea when the situation was wrong.

Although Ding Shisheng's brows did not stretch, he finally nodded: "Okay, but everyone is not allowed to enter the four miles of the main house, and they must not make a noise to affect the main house." ”

"I'm afraid it's a bit difficult, because you need a lot of raw materials to build a ship, unless you can get to the sea. And the shipbuilding will definitely make a noise, if it is during the day, it will not affect the main house, but at night it is difficult to say. If you have to, you can stop work at night. Xin Yu shrugged.

"Whatever you need, we'll deliver it all. Work must be stopped at night, even during the day, and on special days, of course, we will notify you when we need to stop work. Ding Shisheng said.

Xin Yu nodded indifferently and said, "Except for the materials, everything else is arranged by you, how to calculate my salary?"

"Twenty taels of silver per month, and the Chen Mansion is responsible for all your family's food and clothing. Because I don't know that Xin Yu's wisdom value actually exceeds this level, the salary given by Ding Shisheng is quite kind, and there is no hint of oppression. After all, as the chief steward of the Chen Mansion, his monthly salary is only ten taels of silver.

Xin Yu was basically satisfied with this treatment, so he readily agreed to accept the employment of the Chen Mansion. While signing the agreement consisting of these clauses, he laughed at the fact that this contract, which lacked strict provisions, had too many loopholes that were unfavorable to the Chen government.

Obviously, Ding Shisheng is overconfident, thinking that Xiaograssroots is just material for the Chen Mansion, no matter what loopholes there are, Xin Yu does not dare to cheat. Of course, the two sides are not the same heavyweight at all, the so-called contract is just to take care of the emotions of this little brat, if the Chen Mansion really does not fulfill their obligations, no one will uphold justice for Xin Yu, a little fart. As an unequal partner, the Chen Mansion does not need to rely on the contract to bind Xin Yu, as long as they feel that something is wrong, that is, you have not done a good job, and there is no need for a reason.
