The next day, the fleet departed.

Shen Yanqing stood in the command cabin, and when she raised her eyes, she could see that the dark clouds were rolling in the sky, and the small flag on the bow indicating the direction of the wind showed the wind direction at this time, the northeast wind.

The wind was very strong, and the sails were hunting, bringing a slight chill.

Where is this autumn wind, it's almost like the tenth winter wax moon, Shen Yanqing muttered in a low voice, "I'm afraid it's going to snow again." ”

Near the bow of the boat, Yang Bo, Xu Wenjue, Han Zanzhou, and Zheng Zhihu held on to the side of the boat, chatting happily, only hearing them laughing from time to time, talking about something, but Shen Yanqing couldn't hear it at all.

Shen Yanqing couldn't help but look at Yang Bo, this guy has grown taller again, his posture is more handsome, and his temperament is becoming more and more calm, standing in the wind, his long hair is fluttering, and he feels like a jade tree in the wind.

Shen Yanqing looked at it, her heart moved, and Yang Bo at this time, like telepathy, suddenly looked back in the direction of the command cabin, and seemed to smile.

Looking back and smiling, he was talking about beautiful women, but Yang Bo looked back this time, and the lethality was also very great, after all, Yang Bo was born with a troubled face, and he was really handsome.

As soon as Yang Bo turned around like this, Shen Yanqing blushed, her heart was pounding, and her mouth was upturned, "Dead Yang Bo, what do you look back at if you have nothing to do?" ”

The Shen family's fleet is going to make a slight detour to the northeast, they first have to go to Peach Blossom Island and join Lei Jizi, and the dozens of women who were rescued last time will also be picked up on the boat and taken to Shenjiabao.

Yang Bo has already talked to Shen Yanqing, and those women will be dealt with by Shen Yanqing, some of them are spiritual, go to the hospital, be a helper for Shen Yanqing, and the rest will go to work in the factory. Minors, let them go to the school, the next year will be spring, and the new school in the stone temple will also be opened.

The wind direction at this time is northeasterly, and the fleet is sailing northeastward, which is actually sailing against the wind.

Although people at this time still can't figure out the principle of sailing against the wind, in practice, the Shen family's fleet can be easily controlled, allowing the ship to break the waves in the headwind, which shows that the technology of sailing against the wind is quite mature in Daming.

Yang Bo stood at the bow of the ship and looked down, the bow of the ship was like a huge plow, tearing open a hole in the seawater, stirring up white waves, colliding head-on with the huge waves rolling in front of him, and suddenly the turbid waves were emptied, making a roar, which was very spectacular.

Yang Bo couldn't help but feel dizzy for a while, the chrysanthemum tightened, his heart went up and down, and he quickly stood up straight, holding the side of the boat tightly with both hands, and the hull of the ship was very oblique at this time.

"Yang Bo, why is this hull slanted? It feels like it's going up for a while, and then going downhill. Xu Wenjue asked curiously.

Indeed, the zigzag of walking, the past, the uphill, the coming, the downhill, in fact, the angle of the hull tilt is changing, and that's it.

"If the boat sails against the wind, the boat goes in a zigzag, and the hull of the ship must be tilted." At this time, the wind was very strong, and Yang Bo needed to shout loudly to speak.

"What's going on here?" Xu Wenjue asked Zheng Zhihu, and in Xu Wenjue's opinion, Zheng Zhihu is more like an expert than Yang Bo.

There is a way, but Zheng Zhihu doesn't know, Zheng Zhihu shook his head, and in the end, Xu Wenjue still turned his inquiring gaze to Yang Bo.

The power to sail against the wind also comes from the sails, which can be explained by Bernoulli's equation, which belongs to the category of fluid mechanics, just as the lift of an airplane flying in the air comes from the wing, and the upper part of the wing should be designed as an arc.

These theories are very advanced, of course Yang Bo can't tell them this, and no one can understand them.

The sail used by the Fu ship belongs to the hard straight sail, in fact, it is not conducive to sailing against the wind, because the range of the sail bulging is limited, if the soft sail is used, the speed of sailing against the wind can be increased a lot, it can be seen that the principle is not clear, only know one, do not know the other, or is not conducive to technological progress.

Knowledge is power, the ladder of technological progress.

Yang Bo also plans to build his own ship, and of course he will choose soft sails instead of hard sails.

However, Yang Bo gave a lecture to Shen Yiming today, just talking about the balance of inertia and force, so Yang Bo also bought a spinning top in Dinghai and used the gyroscope as a teaching aid to explain to them the balance of inertia and force, which happened to have some connection with this.

"Why can a ship sail against the wind? It's hard to explain clearly for a while. Yang Bo was also in difficulty, thought for a while, and said: "Later, I want to give Yiming a lesson on the principle of things, you might as well listen to it, maybe it will help." ”

"The ship can sail against the wind, and there is also a reason for the object? We want to hear about it, too. Han Zanzhou said with a smile.

"Of course, everything in the world, the operation of birth and death, contains the principle of things, but we don't know most of the principles of things."

"The ancients wrote the Book of Changes, and people said that if you are familiar with the Book of Changes, you will be able to learn from things, isn't it enough?"

"It's not enough, the truth of things, we don't know a lot, sometimes, we don't even know we don't know, of course it is possible that we know, but we don't know we know." Yang Bo pretended to be profound.

“....”

When they arrived at class, Shen Yiming and Le Shui didn't arrive, Pu Peiyao and Xiang'er came early, and Xu Wenjue saw that Pu Peiyao was also there, so he immediately stepped forward.

"Sister of the Pu family, get out of the hall and play chess with your brother, okay?" Xu Wenjue teased.

Pu Peiyao glanced at Xu Wenjue and said, "Little grandfather, you are so fat, you should go to climb the mountain, you are not good at chess, and you will grow fat when you play chess." ”

“...”

Pu Peiyao is beautiful, but the tone of her voice is very impulsive, and when she said this, Xu Wenjue almost choked to death.

Pu Peiyao is only 15 years old this year, at this age, in the next generation, she is a little girl, in the third year of junior high school, in adolescence, she is very rebellious. Although it is now the Ming Dynasty, there is no saying that the youth rebellious period is, but you can't deny that the youth rebellion also exists, her family is good, pampered, rebellious, what's so unusual?

Xu Wenjue glanced at Yang Bo, obviously asking Yang Bo to help, if Yang Bo didn't help, Xu Wenjue should be suspicious, could it be that you Yang Bo has so much meaning to this girl?

Pu Peiyao was born beautiful, but obviously not Yang Bo's favorite type, Yang Bo is a beautiful leg control and likes long legs, but this is a secret, Yang Bo naturally won't say it.

Yang Bo is now interested in managing his network circle, and Yang Bo, who came from later generations, knows that connections are resources, and the relationship network is very important.

Children playing in the mud under the big locust tree have to form a gang.

Now it is a feudal society with all kinds of evils, with strict hierarchies, and everything must be paid attention to, and it must be even more so.

Yang Bo in his previous life, he was a courier brother, exposed to the wind and sun every day, sending packages to people, not to mention the hard work, but also attracting people's eyes, Yang Bo didn't have a beautiful dream, the kind of Cinderella express brother version, fantasizing about meeting a beautiful woman one day, the beauty saw him so hard, moved to the point that he couldn't do it, invited him to come in for tea, came and went, the beauty expressed her admiration for him, so they fell in love, and finally got married, after marriage, they had a car and a house, happy, everything was so beautiful.

Wake up, little brother, it's in a dream, the truth is that the beauty won't look at the little brother more, if you meet a second wife or a third or something, it will throw you a few white eyes, just because of the sour smell of sweat on your body.

To be created equal is to say that we are born with equal opportunities, and even then, it is an illusion.

Xu Wenjue is a nobleman, he has the identity of a prince, and he may also have the title of Duke of Wei in the future, Yang Bo has to prepare a net, like Xu Wenjue, who is the core figure of his network, he must be netted.

Yang Bo seemed helpful, and hurriedly said: "What's wrong with being fat, fat looks rich." ”

"Yang Bo, I don't read much, and I haven't finished the Four Books and Five Classics, don't lie to me."

"I'm fine, what are you doing with a little girl?"

"Am I a child? How much older are you than me? Cut..."Pu Peiyao was quite disdainful, stood up, and said: "From today on, I will provide you with your diet, I will make you delicious food every day, I will let you eat whatever you want, and I guarantee that you will grow a hundred catties of fat in a month, so that you will also be rich, so what?" ”

Yang Bo spread his hands and said, "Wenjue, you better go climb the mountain." ”

"Okay, then I'll go hiking in the future." Xu Wenjue gritted his teeth and said.

As everyone was talking, Shen Yiming and Leshui also arrived, and Shen Yiming was still holding a smooth wooden board in his hand, which was prepared by Yang Bo, and Yang Bo started class.

The plank was placed on the deck, one end was raised, forming an acute angle, and Yang Bo played with the spinning top on the deck, until he used the whip tip to pull the spinning top onto the plank, and the top spun rapidly, and for a moment fixed on the plank, motionless, obviously in a state of balance.

After putting away the gyroscope and the wooden board, Yang Bo talked about the balance of inertia and force, and did a force analysis of the gyroscope on the blackboard, telling that the reason why the gyroscope stood firm was because he was affected by a set of balancing forces, and inertia caused it.

Yang Bo is very sure that only Shen Yiming and Leshui can listen to it in class, and the others will listen to the excitement, this lesson is prepared for Shen Yiming and Leshui, and everyone else is here to rub it, Yang Bo doesn't care, how much they can understand, it would be good to arouse their curiosity.

.....

After lunch, the fleet arrived at the sea near Peach Blossom Island, and Lei Jizi took a small ferry and got on the No. 1 boat where Yang Bo and the others were.

Lei Zhizi and Xu Wenjue are already quite acquainted, and when they met, Lei Zhizi quipped: "Little grandfather, you will eat less hot pot in the future, and you will be fat again." ”

It's really a pot that can't be opened, it's tantamount to sprinkling salt on the wound, Xu Wenjue felt extremely angry in his heart, but after all, he has a noble status, and he doesn't disdain to be angry with Lei Zhenzi.

"Grandpa Ben decided to climb the mountain every day in the future, and this fat will slowly decrease." Xu Wenjue sneered at each other and said: "And you are thunderous, but there is no way to do it, it's a pity, hehe." ”

Lei Zhizi didn't take it to heart at all, Yang Bo introduced Zheng Zhihu to him, but Lei Zhizi knew that the Zheng family was definitely a proud family at sea, so he immediately stepped forward and hugged him warmly, which was all learned from Yang Bo.

Zheng Zhihu obviously didn't get used to it yet, and he was embarrassed again.

Xu Wenjue heard that there was Peach Blossom Island ahead, and blurted out: "Peach Blossom Island? Presumably, there must be a peach orchard on the island, but the season is not right, otherwise, our brothers can follow the example of the ancients and come to a peach orchard with three knots, which can also be passed on as a good story, hahaha. ”

Lei Jizi laughed and said: "Another one, this peach blossom island is called Peach Blossom Island, but there are no peach blossoms on the island." ”

"Really?" Zheng Zhihu said strangely, "Without peach blossoms, why is it called Peach Blossom Island." ”

"Why is that? Let's hear it. Han Zanzhou also felt strange.

Yang Bo had no choice but to learn the legend of An Qi Mountain again, and everyone was stunned when they heard it.

Lei Zhenzi was silent, thought for a while, looked quite a chicken thief, and said: "Although there are no peach blossoms on this Peach Blossom Island, a peach blossom island is always bigger than a peach orchard, not to mention that the island is also rich in peach blossom stones. ”

Yang Bo, Xu Wenjue and Zheng Zhihu heard this, you look at me, I look at you, they were silent for a while, Xu Wenjue was just a joke just now, but at this time, Lei Zhizi mentioned it again, but the feeling was different.

"Why not?" Xu Wenjue pondered for a moment, gradually raised his eyebrows, and said hurriedly: "Lei Zhenzi is a man, but this idea is very much in line with my intentions." ”

Yang Bo and Zheng Zhihu were also pleased, and said: "The three knots of Peach Blossom Island are good." ”

"Our family is optimistic, hehe." Han Zan Zhou struck the festival and applauded.
