"Master crane, dumpling him?" Tianjin rice was in a hurry. The appearance of dumplings was very weak at first sight.

    "It''s all right, just in a coma." crane fairy said with a gloomy face.

    "Coma? Well, how can I be coma? And even my mind calls..." Tianjin Rice said anxiously. Dumplings are connected with Tianjin rice. Even if he fell asleep, Tianjin rice can wake him up through mind calls. In this case, unless

    "Dumplings, this seems to be overuse of super power. How can you overuse super power?" Tianjin rice looked at crane fairy.

    "This..." the crane fairy touched her beard and turned her eyes. "It''s like this. Because she lost in Kling''s hands this time, and saw that sun Wuben was so powerful, the dumplings were stimulated, so just when you were fighting with sun Wuben, you practiced your super ability alone, and the result was overused."

    "That''s right!" Tianjin rice always thinks it''s wrong.

    "Thanks to your lying, you don''t blush." buma, three meters away, shouted, "that boy obviously used his super power to help Tianjin rice deal with the bastard surnamed sun. They can''t win together. What can he do?"

    "What?"

    Tianjin fan was stunned. He looked at buma.

    "What are you talking about? You said Sun Wu was fighting me with his super power of dumplings?" Tianjin fan cried incredulously.

    Buma said goodbye with disdain.

    "Little girl, don''t talk nonsense." the crane fairy couldn''t hang her face, stared at buma and threatened, "you know, you can eat rice and don''t talk nonsense, otherwise..." the crane fairy stretched out a finger and a ball of light appeared in his hand.

    "Yes, don''t talk nonsense!" Tianjin fan shouted.

    "Otherwise, you think it''s your own ability to beat the bastard sun for a while?" buma shouted directly behind Yamcha. "Believe it or not, it''s your own business."

    "You..."

    Tianjin fan pinched his fist and turned to stare at crane fairy angrily.

    "You... Did you make dumplings?"

    "I... I haven''t seen that you can''t win!" crane fairy stepped back in fear, and then became angry. "Tianjin rice, what are you doing? Do you want to do something to master?"

    Boom!

    The head of Tianjin rice seemed to explode.

    "It''s true..."

    Tianjin rice trembled and stared at the crane fairy.

    "Why? Why do you want to meddle in my affairs? Why don''t you let me fight with sun Wuben? Why..."

    "Hum!" the crane immortal snorted.

    After a burst of fire, Tianjin fan picked up dumplings from his chair and went directly to sun Wuben.

    "Huh?"

    Sun Wuben looked at the Tianjin rice in front of him.

    "Sun Wuben, I want to know where I lost?" Tianjin Fan said in a deep voice.

    Sun Wuben picked his eyebrow and smiled: "Tianjin rice, I thought you wouldn''t say such words."

    "If you lose, you lose. I admit that you really looked down on people." Tianjin Rice''s voice was cold. "This time, you are better than me, but I will win back."

    "I believe." Sun Wuben nodded. "I always believe you can do it, but I won''t lose to you."

    "You will lose to me!" Tianjin fan Leng hum.

    "Although I always told you that the cultivation of martial arts is the first, what martial artists want is not to fight hard, but the sublimation of life, but this time it has nothing to do with this," said Sun Wuben.

    "You mean your strength cultivation is not much better than me?" Tianjin Fan said in surprise.

    "You don''t have to be surprised. You should know that your physical potential is much higher than mine. If I use the same cultivation method as you, I am thankful to be able to achieve the achievement of Yamu tea. What I am stronger than you lies in the use of strength."

    "Are you talking about the realm of martial arts?" Tianjin fan looked forward to seeing sun Wuben. In the past, even the simplest way he talked about martial arts to sun Wuben has always been skeptical, but at this time... Tianjin fan is very sincere.

    "That''s right." Sun Wuben nodded, and his back hand pointed around, "you see, the air around us seems empty, can''t be grasped or touched. In fact, he has resistance. For example, he shoots a bullet from a gun at an angle into the sky. If there is no air resistance, the distance he can shoot will be far, specific..."

    Buma also crowded in front of Sun Wu. She was supposed to verify Sun Wu Ben''s true identity. At this time, she couldn''t help but interrupt proudly.

    "What do you know? The bullet is in the ultra-low speed state. The air resistance is different between the low speed state and the high speed state. The air resistance of the bullet can be ignored. According to the air resistance formula F = (12) C ρ SV ^ 2, plus gravity (g = 9.8), C is the air drag coefficient, ρ For the air density... "Bouma muttered and calculated, and then said proudly," generally speaking, a bullet can shoot 40 kilometers without air resistance, but with air resistance, it''s good to shoot 4 kilometers. "

    Tianjin rice stared.

    "Woman, are you mistaken?" Tianjin Fanman stares at buma suspiciously. "You say there is no air resistance, the bullet can shoot 40 kilometers, and with it, it can only shoot 4 kilometers. This is called ultra-low speed, and the air resistance can be ignored?"

    Buma was angry.

    "You big idiot, dare you doubt Miss Ben''s calculation? A talented and beautiful girl like me bulma will even miscalculate this knowledge of fluid mechanics?"

    Tianjin fan snorted and turned his head to ignore buma.

    "Sun Wuben, go on," said Tianjin fan.

    "Asshole!"

    Buma glared with anger.

    "She''s right." Sun Wu had already calculated the air resistance. "The air resistance is very small at the ultra-low speed where the bullet is located. There is nothing wrong with the calculation of 40 km and 4 km. If there is no gravity, a bullet can fly indefinitely after it is fired."

    "How could it be?" Tianjin fan was surprised. Although what sun Wuben said was beyond his expectation, Tianjin fan still chose to believe it.

    "Generally speaking, the speed of 200m is a barrier, especially when it reaches the speed of sound, it will gradually catch up with the sound wave emitted by itself. At this time, because the compression of the body on the air cannot spread rapidly, it will gradually compress and accumulate around the body, and finally form a sudden change surface of physical properties such as pressure, temperature, speed and density in the air - shock wave..." Sun Wuben talked with assurance.

    Tianjin fan smiled bitterly: "I can''t understand what you said about pressure, density and shock wave."

    "Idiot!" hummed buma. "It''s terrible to be illiterate. These Pediatrics don''t understand common sense. No wonder you can''t beat others if you have muscles in the air."

    Tianjin rice skimmed and ignored buma.

    "Simply put, when the speed reaches a certain level, the resistance will suddenly increase greatly," said Sun Wuben. "Just like a steel wall suddenly appears in front of you, you have reached this level, you should understand."

    Tianjin FanMei said, "that''s what you''re talking about!" when he punched out, he only heard a loud noise from the tent.

    "Yes, you''ve just punched. The speed is close to the sound speed, so there''s a sonic boom, which is scientifically called the sound barrier." Sun Wuben said in a deep voice, "have you ever seen a supersonic aircraft? The appearance of a supersonic aircraft is completely different from that of a normal aircraft. This is to break through the sound barrier, because when the speed reaches that level, you can''t break through the sound barrier simply by increasing power."

    "I see." Tianjin rice suddenly.

    "Let Miss Ben tell you that the resistance in the air is proportional to the speed," Boomer interrupted proudly, "Generally speaking, at very low speed, it is the first-order square ratio, so we can''t feel the resistance. At ordinary speed, it is the second-order square ratio. When it reaches 400m to 600m, it is the third-order square ratio. By analogy, the faster the speed, the greater the resistance. Therefore, at low speed, you martial artists don''t have to consider the air resistance when shooting, because the resistance at that point is almost zero, and you just hit it The sonic boom belongs to the second level, that is, the level of ordinary speed, that is, the square ratio. At this time, you can feel the pressure of resistance. Then, the more you increase the speed, the greater the pressure. "

    "Is that so?" Tianjin rice looked at Sun Wuben.

    "That''s what she said." Sun Wuben said.

    "I''ve understood." Tianjin fan Shen said, "no wonder jiaozi and I can''t improve the speed of body movement and boxing when we improve our cultivation to a certain extent. We often have to increase our cultivation a lot to improve our speed. We don''t start to improve until we finally practice Mr. crane immortal''s boxing."

    "Yes, boxing is just like changing the shape of an ordinary aircraft to the shape of a supersonic aircraft. It can greatly reduce the air resistance, or even have no resistance at all. The stronger one can make the air flow push you forward in turn. This is the highest martial arts, but this martial arts is useless in low martial arts, just like changing the shape of an ordinary aircraft to a supersonic aircraft It won''t increase much speed, but once you enter gaowu, the higher the level, the greater the role. "Sun Wuben lamented that at this martial arts conference, the combat power of Guixian was up to 139, while Tianjin rice was 180, but Guixian was not afraid of Tianjin rice, and even won Tianjin rice, relying on the strength of martial arts.

    There are too many superfluous movements when Tianjin rice is punched, and a large part of the force is stopped by the resistance of the air flow. Moreover, the faster Tianjin rice is, the greater this resistance is.

    The tortoise fairy, with each fist and foot, can almost completely ignore the resistance of the air, and even let the air flow push his fist in turn, so he is not afraid of Tianjin rice at all.

    On the contrary, it is the crane immortal. Although the martial arts cultivation is similar to that of the turtle immortal, the combat power is only 120, which is a little different from that of Tianjin rice. It is very difficult to deal with Tianjin rice.

    "I see." Tianjin Fanshen said, "cultivation is fundamental, but martial arts can''t fall down, because speed is directly proportional to resistance. The faster the speed, the greater the resistance. Therefore, only martial arts can keep up with cultivation, can we give full play to our strength."

    "The truth is roughly right, but you have to think about it yourself. If you specialized in martial arts instead of improving your accomplishments, you wouldn''t have such achievements now. At most, it''s a little better than that puff," said Sun Wuben.

    Tianjin fan nodded gratefully: "I know what to do, sun Wuben. Next time, I will be able to win you!"

    "I''m waiting for you. By the way, dumplings are like this... Let me see."

    "HMM." Tianjin rice handed over dumplings. After sun Wuben took it, he looked at it slightly, and his eyebrow was a pick.

    "How about?" asked Tianjin Fanlian.

    "Martial arts cultivation is to cultivate the three treasures of the human body, essence, Qi and spirit." Sun Wuben said in a deep voice, "essence refers to our body, Qi, you know, and God can also be used to attack. Dumplings use super power, which consumes God to attack. He consumes too much God. I''m afraid it will recover very slowly."

    Tianjin fan''s face showed surprise.

    "Yes, dumplings are really overused. They have appeared once before. That time, he slept for seven days, and then it took a month to recover. Sun Wuben, what can you do?"

    "It''s very difficult. God is the foundation of life. I don''t dare to mess around at will. The dumplings are reckless." Sun Wuben sighed. "As for the methods, the essence, Qi and God complement each other. If the essence is enough, the recovery of God can be faster."

    "Enough Qi after refined?" Tianjin rice smiled bitterly. "It seems there''s no way."

    "I heard that immortal Kailin has a kind of fairy bean. If you take one, you can stay hungry for ten days. This is a good baby to supplement your essence. Unfortunately, I don''t know where immortal Kailin is." Sun Wuben said.

    "Fairy bean? Fairy Kailin?" Tianjin rice shook his head. "There''s such a thing? I haven''t heard of it, but even if there''s such a baby, it''s useless. Dumplings are in a coma now. How to eat?"

    "This is really a problem. Well, put the dumplings here first. I''ll try to see if I can help him recover quickly, but I can''t guarantee it." Sun Wuben said.

    "Thanks a lot." Tianjin Rice turned back to crane fairy.
