How is the mast of a sailboat designed, and why can it sail upwind? What kind of structure is the bottom of the cabin to ensure that such a large ship will not break in strong winds and waves? If the oar hole of the oar boat is too low, won't water pour into the boat? But if it is too high, how long should the oar be, and how can it be used to paddle? Yes, in comparison, Chen Shou was more interested in old-fashioned sails and paddle boats. He somehow felt that old-fashioned sails and paddle boats were more like a real life than later generations of steamboats. The flying boat tested in the Daoguo Conference this time is obviously more like the soulless steamship used by Chen Shou in his previous life, which is not the kind he likes. However, the fact is that at least two reasons have stimulated his great interest in the flying boat he will refine this time: first, the quality of the flying boat is directly linked to the reward; second, his flying boat will be completely designed, selected, and produced by him. Refining, this process will allow him to inject vitality into the flying boat. Think about it, once the Feizhou is successfully refined, what will be the difference between the handmade Swiss watches and European luxury cars of the previous life? Is the sense of achievement bursting! You must study hard! At the front of the hall, Hu Yun's basic course explanation came to an end, and he finally said: "I remind you again that the water suspension performance of the airship must be good this time. Its importance even exceeds the high-altitude flight ability and underwater submersion ability of the airship. Okay, Let's do this for now. Now I will introduce you to the teachers of the special courses. " Since Hu Yun particularly emphasized the water levitation, when he finished introducing the special professors and announced that classes would start in separate classes, Chen Shou immediately chose to listen. The professor named Zhenhezi taught a lesson about water suspension. This professor was not the professor at Chen Shou's previous school. It is an honorific title for people in Xuandu Zifu who have profound knowledge in certain aspects. Not even enough time to make a cup of tea. Chen Shou had already arrived in another hall together with more than three thousand other witch cultivators and demon cultivators who had made the same choice as him. Listen to Zhenhezi's explanation. Zhenhezi is dark and thin, about fifty years old, with small and bright eyes. He should be some kind of raccoon or mink demon. This old man obviously didn't like nonsense. He said a total of two opening remarks and then went straight to the topic. Originally, the hall was still a bit messy, and many people were tinkering with the futons under their buttocks. There was nothing they could do. They were really not used to sitting on this thing, but when they saw that Zhenhezi had opened his mouth over there, they all fell silent. "The so-called water suspension means" Zhenhezi's words are clear, short and bright, which is very refreshing. Water suspension is a new term that most people heard for the first time after coming to this hall. However, Chen Shou accepted it immediately because he had heard of "maglev" in his previous life. The principle of water levitation is similar to magnetic levitation. In fact, he had already seen water levitation when he took the Pingchaolou boat from Okuyama to Magic Dragon City. but. Chen Shou still listened very seriously and watched with wide eyes. Because Zhenhezi not only talks about it, but also does it! It has to be said that the prehistoric world is a very mysterious world with traces to follow. By carving a specific talisman array on ordinary materials, and then stuffing a piece of talisman jade into it, that piece of material will most likely turn decay into magic, producing incredible phenomena. Just like now, while Zhenhezi was explaining, he took out an amber slate from the storage ring and quickly wrote on it with his sword finger. It was done in one stroke. Then Hou Zhenhezi embedded two pieces of fourth-grade talisman jade on a hinge of the stone slab talisman array, and then heard a "buzz" sound, and the entire stone slab emitted a faint brilliance and suspended in mid-air. However, the stone slab was shaking and obviously not stable. "There is water vapor in the air, but it's too thin to be seen with the naked eye, but it's still enough to make this board levitate. Now, look." Zhenhezi touched his left hand under the stone board, and a large area of ??clear water appeared out of thin air. When he appeared, he flew under the stone slab. As the clear water appeared, the stone slab above trembled slightly, seeming to echo the water flow below. It rose a little first, and then stabilized completely. "The stability of the flying boat is also related to the structure and the talisman array specially designed to maintain stability. However, the water-suspended talisman array is a keynote. Whether the repulsion generated by it and the water is stable and the size determines the stability of the flying boat" Zhenhezi He talks eloquently on the stage, and his words are short and bright, which seems to be able to reach people's hearts. I have to say that he is a real teaching talent. Occasionally, when Chen Shou was distracted, he thought to himself that if Zhenhezi were placed on the earth, he would probably be at least a world-famous academic master. However, it's a different story in the prehistoric world, because it's so big here and there are so many talented people. It wasn¡¯t until evening that Zhenhezi announced the end of get out of class, allowing the contestants to move around freely. In fact, this is just for the contestants to communicate and have a meal.?Take a break or something, there are classes in the evening! Chen Shou felt like he was back in high school or college. To be honest, although those days were spent studying and studying, which was miserable, they were still quite fulfilling. Looking back, he felt quite nostalgic. Taking advantage of this time, Chen Shou sat on the futon in the hall and integrated the knowledge taught by Zhenhezi. His understanding of the water levitation array has obviously improved a lot. At this moment, he is not the only one who is still sitting here, but there are many. Everyone was meditating and communicating, and it seemed to be quite an academic atmosphere. However, if you look at it carefully, you can clearly see that many people are actually frowning. Although what Zhenhezi said is not profound, it is still a bit difficult for people who have come into contact with the water suspension array for the first time. , not easy to get started. " Chen Shou obviously does not belong to this category. He was particularly good at physics in his previous life, and it was even his strongest subject. In this life, he has the help of Haoran Yuanshen. This powerful Yuanshen can make him smarter and greatly improve his thinking speed, logic, analytical ability, memory, etc. The water suspension formation is just a little unfamiliar to him, but it is not difficult. Only half an hour later, Chen Shou finished integrating the contents, and then seeing no acquaintances in the hall, he went directly to the outside. There were classes in the evening, but he still had a while before leaving class. He wanted to go to the new dormitory arranged for them by Xuandu Zifu first, so as not to have to look back again. After the temporary third hospital accommodated these 10,000 contestants, it was obviously very lively, and there were people everywhere. Chen Shou stretched when he got outside, then looked at those people and couldn't help but said, these are all competitors! And it is a very strong competitor! There are so many people who came to Qingjing to participate in the Daoguo Conference, and 80,000 people were finally selected to participate in the most important competition. Who is not the elite among the elite? You must not take it lightly! Chen Shou took a deep breath and then moved forward to find his dormitory. After walking through the corridor, Chen Shou found his temporary residence on the east side of the temporary third courtyard. The accommodation was arranged by Xuandu Zi Mansion, and since 10,000 people came at once, it was a bit too much, so the accommodation conditions were far inferior to those in Chen Shou's private courtyard. Anyway, it was only seven days, so I gritted my teeth and got through it. A gray wooden board was nailed to the wall next to a room, with four names clearly written on it, and Chen Shou was among them. It was obvious that he was going to live with three other people. Chen Shou walked directly to the door and heard the sound of people before he entered. "Isn't this a lie? There are seven days in total, and you have to refine it on the last day. In fact, there are only six days. Who can learn this?" A loud voice complained. "Yes! Which of our witch cultivators is not exercising at this time? How many of us are studying talismans?" Another voice echoed impatiently. Chen Shou had already reached the door, and his footsteps immediately stopped. There were actually two witch cultivators in the room! ????????????????????????? How did the Xuandu Zifu arrange this, and how did it arrange the demon cultivators and witch cultivators together? He frowned and then stepped in. Chen Shou did not deliberately step lightly. The two people in the room immediately looked over at him, and he looked over. Both of the two witch cultivators were in human form, but one had a sturdy figure and a pair of terrifyingly large arms. Chen Shou could tell at once that this man was from the more famous Eight-Armed Clan among the witch clan; the other One of them had a thin figure, eyes as sharp as knives, and a fierce aura. Chen Shou couldn't tell what clan he belonged to. The relationship between the witch clan and the demon clan in the earth realm is quite complicated, and Dongqing Shenhuang is the most complicated. When the two people saw Chen Shou, they had no reaction at first, and then the thin guy with sharp eyes nodded to Chen Shou expressionlessly. nod. Those two people definitely didn¡¯t expect that Chen Shou would be greatly relieved at this time. Just because before he came to participate in the competition, he happened to win Chi You, who was extremely famous among the younger generation of the Wu clan. Everyone in the Wu clan was shouting for a fight, so he was really afraid that the other party would recognize him. If two insiders really lived in the same house with him, he would probably not be able to live in peace. Chen Shou also nodded to the man expressionlessly, and then began to look at the environment in the room. The room was not big, about twenty square meters in total, with two beds on each side. There was a small wooden sign on the wall next to the bed on the right, with his name written on it. Chen Shou walked straight over there and saw that there was nothing else except a bed and a small cabinet, so he lost interest in reading any more. Anyway, he just came to explore the road first so that he could come back at night. Without saying hello to the other two, Chen Shou turned around and walked out, taking a look at the bed on the right side by the door.I saw the word "Wuling" written on the wooden sign, and I didn't know if it was a witch cultivator or a demon cultivator. As soon as Chen Shou walked out of the house, the two people in the house started talking again. It can be seen from the wooden sign that the guy from the eight-arm clan is named Yan Kuo, and the guy with sharp eyes is named Qiu Kong. Yan Kuo said: "Is this arrangement intentional by the Purple Mansion of Xuandu? In my opinion, Wu Ling must be a demon cultivator." Since he has this judgment, it can be seen that he is also a person who is willing to use his brain. However, Qiu Kong looked thoughtful and said: "Don't you think the name Chen Shou is familiar?"
