Chapter 6: The Secret of Lightness Kung Fu

  "Some of your explanations are very clear and incisive," Ge Gu praised.

  Ge Gu is eighty years old this year, born in the early 20th century, and has never studied biology or physics. Naturally, he can't speak as clearly and systematically as Li Peicheng. But that doesn't mean he understands less about why birds can fly than Li Peicheng does. Just like a farmer with rich planting experience, although he hasn't attended an agricultural university, he knows how to plant crops, and may even be more skilled than some agricultural experts.

  "My disciples are all from books." Li Peicheng said humbly.

  Ge Gu nodded and said: "Weight and lift are the biggest problems that people can't fly. If people want to fly, they must solve these two problems."

  Li Peicheng nodded secretly and perked up his ears to listen.

  "We cultivate, open up the meridians, absorb the essence of heaven and earth, and discard the impurities within our bodies. After a long time, our bodies will be filled with the essence of heaven and earth, and we will no longer feel as dull and heavy as before. If we can open up all the meridians in our body and reach the state of great perfection, it means that there will be no more acquired impurities within us, and our bodies will be light as a swan, able to fly freely in the heavens." Ge Gu said.

  Li Peicheng suddenly realized that he had been enlightened. No wonder since his cultivation, he felt as light as a swallow, it turned out to be because of this reason.

  "It's just that to achieve a light body like a swan, it's not easy to talk about, even if one cultivates to the sixth realm, it's only superficial. Ge Gu paused for a moment, then continued: "Therefore, martial artists have come up with two methods to overcome the obstacles brought by weight. One is to use leg strength, borrowing force to rise; Two is to borrow the power of air, maintaining human flight in mid-air."

  Li Peicheng was very puzzled by this, and it was easy to understand with the help of his feet. A martial artist's leg strength is extremely strong, and their body is lighter than that of an ordinary person, so when they exert force, they can indeed jump a distance in mid-air that an ordinary person cannot reach. However, using air to sustain flight for a period of time seems somewhat inconceivable. According to Li Peicheng's understanding, the density of air is so small, and the density of a human being is so large, how can the buoyancy of air support a person? It's still possible in water.

  "Master, I understand how to borrow strength from my legs, but how can I borrow strength from the air? I don't understand," said Li Peicheng.

  Ge Gu smiled and said, "This is where the secrets of Ti Zong technique lie, you naturally wouldn't understand."

  Li Peicheng scratched his head, and indeed, if Master didn't say it, he would have known himself, but this was a bit too easy.

  "You have now reached the second realm, and the circulation of yin and yang in your body has been completed. You can control the release of true energy. When you release true energy, divide it into two parts, with the lower part being flat and the upper part being raised. The air will be affected by your true energy and generate lift. With a kick, the true energy is released and rises, and when the true energy is exhausted, it falls to the ground."

  Li Peicheng was stunned upon hearing this, his mind filled with a string of formulas, that of Bernoulli's theorem, the principle of airplane flight.

  Bernoulli's theorem - the faster the fluid flows, the smaller its static pressure; conversely, the slower the fluid flows, the greater its static pressure. The upper surface of an airplane wing is curved to accelerate the airflow, so that the pressure on the upper surface is small, while the lower surface is flat and the airflow is slow, resulting in a larger pressure difference between the two surfaces, thus generating lift, which is one of the most important reasons why airplanes can fly. Now it's just a matter of changing the wing to true energy.

  Ge Gu saw Li Pei Cheng stunned there, knowing that this principle is a bit unbelievable. When he first learned the art of flying, his father told him that controlling the true energy down flat and up convex would allow him to fly further in the air, but he couldn't understand it either, until he tried it himself and found out that it was indeed a wonderful thing.

  Ge Gu didn't know, but Li Peicheng had already understood this principle. However, he never thought that once the veil of Ti Zhong Shu was lifted, it wasn't mysterious at all and was closely related to science and the laws of nature.

  A flash of lightning flashed out dazzling light and fiercely crossed Li Peicheng's head, something was about to emerge in his mind, Li Peicheng seemed to grasp something.

  Science, yes, cultivation is also a science. The essence of heaven and earth absorbed into one's body is a kind of energy, a kind of energy that only a very small number of people know about and grasp. They unknowingly use this energy, summarize some rules, even perfectly utilize these rules, but do not know its true nature.

  Just like an excellent archer, he knows at what wind speed and with how many shooting angles can just hit the target. This has almost become their instinct. They make good use of force and parabolic principles, but they do not know the core truth that truly determines the accuracy of their arrow shooting.

  Li Pei Cheng suddenly became enlightened, although his inner strength had not increased in the slightest. However, due to this epiphany, his entire spiritual level was instantly elevated to an unimaginable height, which is what is meant by "reaching a certain state of mind". Because he had already vaguely seen through the mysteries of heaven, the path of cultivation was no longer mysterious in his eyes.

  Those who are not mysterious cannot be feared; those who are not feared cannot be defeated.

  However, Li Peicheng did not know at that time that such an epiphany would have an unparalleled impact on his future.

  Ge Gu didn't know that Li Peicheng had actually combined the mysterious cultivation with science in his mind, and even if he knew, he would only laugh at Li Peicheng's wild imagination.

  Ge Gu explained to Li Pei Cheng how to control the shape of the true energy release and said: "You try it."

  "Yes!" Li Peicheng responded with a loud voice, his toes suddenly exerting force, and his entire body soared into the air. Two streams of true energy burst out from the soles of his feet, forming an upward convex shape, and he immediately felt two different air flows flowing up and down his body at different speeds. One flow supported him, slowing down his descent to the ground.

  Li Peicheng, having only cultivated to the second level, was far inferior to Ge Gu in terms of weight, strength, and control over his true energy. Naturally, he couldn't fly as effortlessly or as high and far as Ge Gu. Nevertheless, Li Peicheng's first flight attempt left Ge Gu staring in amazement, repeatedly exclaiming in admiration.

  With the Double Boundary, learning the Ti Zhong technique for the first time can already jump 4 meters high and 6 meters far, which is absolutely a miracle in the martial arts world. Even if Ge Gu uses his full strength now, he's only about 7 or 8 times stronger than Li Peicheng.

  Ge Gu didn't know that his apprentice was a top-notch graduate student at a first-rate university. Just now, he had secretly designed the optimal pattern in his mind based on Bernoulli's theorem and air resistance, etc. If it weren't for his control over true energy not yet reaching the level of being able to do as he pleased, with his current abilities, his jumping height and distance could definitely be increased by another 20%.

  Li Peicheng continued to soar, his movements becoming more and more fluid, until he was like a bird flying effortlessly through the air. The aerodynamics were perfectly demonstrated on his body, making Li Peicheng feel extremely excited and thrilled.

  Ge Gu closed his eyes slightly, and his whole body and mind went to feel the true energy released by Li Peicheng. He was amazed again, this disciple had completely grasped the most mysterious link of Ti Zhuan technique just by himself, and formed the most perfect true energy shield around him.

  It's no wonder that Li Peicheng was able to grasp the essence of Ti Zhong so quickly, because he saw through its nature and used the most scientific theory to guide his continuous improvement.
