Douluo See You For a Long Time

　　 Although Chengying has been tempted, knowledge is still a precious thing in this era, and he has to behave a little reserved.

"What can you do when you go to sea alone? Sailing is not something that can be done by one person. I didn't see that I brought these 800 sailors to start this huge ship. If you really want to find your loved ones, you might as well ask me for help. You search for a few laps at sea."

　　 "But I..." Pollan didn't really lose her parents at first, and it was difficult to refute her feelings that were not in place for a while.

"Teacher, don't you often say that teaching people how to fish is worse than teaching people how to fish? How can you replace Pollan sailing, how can you compare to the skills that taught her to sail?" Chengying looked at Tang Chen who stood up to help, and couldn't help it. Hold your forehead with one hand, where is your heart telling you?

"You have to think about it clearly. Knowledge is priceless and it is impossible to pass it to you. Of course, if you formally apprentice it is another matter, otherwise I can only teach you some superficial things." Chengying I feel that in this way, I should be able to take in another apprentice.

　　Unexpectedly, Pollan hesitated, and said after a long while: "Sorry, I'm afraid I can't worship you as a teacher."

　　 "You already have a master?" Chengying was puzzled, and she didn't look like she had a master!

　　 "No, it’s just because of some reasons that it’s not convenient to be a teacher. I can treat you like a teacher, but I’m afraid I can’t be a teacher..." Seeing that Polan’s tangled expression does not seem to be fake, Chengying’s brows were raised.

In all respects, Polan has no reason to refuse to be a teacher, unless... because her identity is not suitable, it is reminiscent of the original work that she has been on the Sea God Island for nearly a hundred years, just to wait for the inheritor of the gods, and finally pay You have to sacrifice yourself to complete the inheritance of the Seagod, I am afraid that his identity is very special.

"Well, if you really don't want to be a teacher, just forget it. For the sake of your sincerity, I will teach you something that I can tell you." Chengying remembered that Bo Saixi was talking to Tang Chen and Qian Daoliu in the original work. As I said, I will only be with the one who has become a god. I am afraid that it is not simply to reject Qian Daoliu. It is very likely that the necessary condition for marrying this girl is to become a god.

Boran was also relieved when she heard this. She was naturally Bo Saixi. As a soul master who was born with the spirit of the Seagod, she was bound to the gods when she was born, and the soul masters on the Seagod Island all got gods The **** of the sea appointed her as a saint, a spirit master who specializes in serving the **** of the sea.

This is undoubtedly the supreme glory for a race that has believed in the Sea God for generations, and since the saint who serves the Sea God is naturally not allowed to be married, let alone the teacher, otherwise, wouldn’t the teacher be on the same level as the Sea God? .

　　Naturally, Bossie, who has become a saint, has gained a respected position on Poseidon Island. She is like the uncrowned king of Poseidon Island. The only restriction is that he cannot leave the place of Poseidon’s heritage.

Unfortunately, Poseidon is on the Seagod Island. Very few people yearn for freedom and want to open their eyes to the world. They have an adventurous spirit. This is the most precious kind of will on a deserted island isolated from the world. It happened to the most inappropriate person.

She ran away countless times, but she was either swept back by the sea or captured by the sea soul beast. Every time she was swallowed by the sea soul beast and spit out, it was a nightmare experience, as if it was the sea **** punishing her. The fleeing in general.

　　 This time I thought I was going to be arrested again, but I didn't want to encounter the world's end passing by. When I caught her back, the Sea Soul Beast was killed directly. With such a huge ship, it is simply the best opportunity to escape from Sea God Island.

But she knew very well that the power of the deity is not something humans can resist. Although the giant ship is strong, it is unrealistic to take her away under the obstruction of the deity. The result of forcibly taking her away can only be Burial in the sea.

　　 She doesn't want to involve innocent people for her own reasons. She just wants to learn as much knowledge about travelling across the ocean as possible before being caught back. In the future, she won't be rushed back by the ocean currents because she doesn't discern the direction.

　　 Naturally, she could not worship Chengying as a teacher, because that would only harm him. No one knows what the character of the sea **** is. If she is particularly careful, she will definitely not allow her saint to have a teacher.

　　 is just a fan of the authorities, she has never thought about why she has escaped so many times and nothing happened...

In fact, Chengying almost guessed the truth, so he also planned to teach Posey's navigation knowledge as much as possible. He believes that even if she can't abduct her, she will run from Poseidon Island on her own. come out.

Then……

　　 Then Bo Saixi realized what the sea tactics are, what is the duck-filling education, with the few people on Poseidon Island, wanting to make a qualified sailing clock is a foolish dream.

　　 If you only know the latitude on the sea, it is just floating around, and there is no clock to determine the longitude, then you can only rely on the stars in the sky.

　　 If you are on the earth, you can see Jupiter or Jupiter's moons. If you are in Douluo~www.wuxiamtl.com~ then you have to observe the star map again.

　　 Chengying hasn't measured the data in this regard, so she had to teach Posey how to confirm the time by observing the stars, and then let her sum it up by herself.

　　 And the problem here is more complicated, let's learn the law of universal gravitation! Calculate the rotation of stars, then learn the conic section! Like proficient use of sextant to observe stars, the most basic analytic geometry should be learned!

Not to mention the more complicated things, such as conic section and analytic geometry. It is terrifying for people who have no foundation at all. Cheng Ying actually wants to say that if you want to calculate accurately, you have to learn calculus, but I think about it. I still didn't teach it. To be more real, he might have to talk about using imaginary numbers to solve cubic equations in one unknown. That is a few years of learning.

　　 And Bo Saixi is also painful and happy these days. Although Chengying’s words are difficult and difficult to understand, they are nicknamed the knowledge of immortals by several other students, but they have indeed benefited her a lot.

Especially after knowing that this thing under her feet is a ball in all likelihood, she has strengthened her determination to go out and take a look. The ground under her feet is so vast that there is a full circle of eighty thousand miles away, let alone Talk about the ethereal sky.

　　 She may not have the opportunity to step outside in her life, but it would be a shame if the earth under her feet missed it again.

　　 The diameter of the planet under my feet is 40,000 kilometers. This was measured by the shadow of the sun using the length of the sun. It can be said to be a coincidence, or it can be said to be inevitable. Otherwise, parameters such as gravitational acceleration will definitely change.

　　 On this day, after Chengying told Posesi how to find the tangent of an ellipse by analytical method, she looked at the dark clouds rolling in the distance and couldn't help but squinted her eyes: "What should come is always here."
