Ultraman tried his best, showing the strength of the ancient god, and then narrowed to the human body. One was a courtesan and the other was a big man. In terms of the image of the human body, it was pretty good and very consistent.

Of course there is also Tiga, who was hidden in the abyss of anger by Duran, and let the thrush mast stare.

Duran took two human bodies to search for other survivors on the island. Those who could survive the first night were masters. Those who were not capable had been killed. Now there are only two groups of surviving, one group was a bandit and the other group was a swordsman.

The bandit was not lucky and met the immortal directly, but the two brothers were still very resistant to fighting. The younger brother was thrown into the pit to make fertilizer, and the older brother was taken away as materials for collecting yin and replenishing yang. But the younger brother crawled out of the mass pit, and the older brother was also patient.

Their brothers have lived a miserable life since childhood. They have endured the crazy suppression of society, but they still survived strongly. Until the end, they will never give up.

On the other hand, Jianhao was imprisoned because he could not find his opponent. His strength was naturally top-notch. He cut melons and vegetables all the way. He has not encountered immortals yet and has survived.

Duran was wandering around the island. When he encountered a monster, he asked the two human bodies to fight. Lu Taro's divine power was further released. He picked up the stone and threw it out, like a cannonball.

"I was originally a stupid guy, but I could only fight in close combat and would not use my own advantages. Now I have learned to use my strength well. Ranged attack is the trick of human beings to be king." Duran fully agrees with Lu Taro's feeling of using long-range attacks and throwing a stone out of a meteor.

"You can try to wrap the air around the stone to increase the hardness of the stone." Duran guided the other party to use the air and said: "Then you can also try to adjust the density of the air to form a pressure difference of the air, so that the high pressure pushes the low pressure and continue to accelerate, and the speed can break through the speed of sound."

The winding of gas and the pressure difference of gas are any technology that can be tried and tested by fluid energy.

According to Dongda University's theory, Qi forms all things, and the internal principle is "Heavenly Principle". The Heavenly Principle is Tao, which is nature. Anyway, everything goes with the flow and does not require any human control, Qi will naturally form all things.

As for the mutual relationship between qi, I don’t know. In short, it is how the qi is arranged, and how it operates.

In science, particles are composed of all things, so why do particles arrange them and not become a mess of sand? Because there is a force between particles. There are strong interaction forces and weak interaction forces between particles. The two forces act at the microscopic particle level, forming the most basic examples to stabilize the world.

In physics, there is the role of force between theory and reality. Any rule interferes with the changes of matter through force, and of course it can also be called "work".

So in metaphysics, all things are composed of qi. How does the heavenly way interfere with and operate qi? Is there also a kind of "force" between qi?

The four basic forces of physics: universal gravity, all mass objects will produce gravity and interact with each other. Electromagnetic force, all charged particles will produce electromagnetic force. Strong nuclear force, particles that form the nucleus will be affected. Weak nuclear force, this is the main reason for the decay of atoms.

The four basic forces influence each other to form a stable world.

So how does metaphysical qi operate? It is generally believed that there are two states of qi. One is active yang energy, and the other is inert yin energy. Yin energy and yang energy constantly transform into each other. The anode produces yin and the yin energy produces yang. This transformation is always running. What forms the substance is yin energy, stable and calm, but the substance disappears all the time, that is, from stable yin energy to active yang energy. When a person dies, the stable yin energy becomes active yang energy.

At the same time, due to the different proportions of yin and yang energy, metal, wood, water, fire and earth...

Therefore, Qi is Qi, and the changes of Qi are internal. Unlike particles that require external forces to restrain them, Qi is the continuous transformation of yin and yang within, but the transformation stage is different, forming all things.

"It can be said that after Pangu opened the sky, the total amount of qi was certain, but qi kept changing to maintain the balance of yang energy and yin energy. The world was never completely stable, but it was not completely active. Yin and yang were changing slowly and did not require the influence of external forces. The internal changes of qi were enough. But if a person's will and determination were strong enough, it could also have an impact on qi and reverse the changes of qi. Therefore, we must seek strength from the inner qi." Duran said that metaphysics usually seeks internal strength, while physics usually seeks external strength.

If a thing does not have external force to do work, it can remain relatively still. It is necessary for external force to do work to break this state.

But according to metaphysics, even if the object remains relatively still, the yin and yang changes are still occurring inside.

"Physics requires external force to do work, but metaphysics only requires mental power to rewrite the internal changes of Qi, so metaphysics is simpler and more convenient." Duran said that it is difficult to do external work, and training mental power is only possible.

Of course, it is not easy to train mental power, otherwise only ten of the more than 100 death row prisoners would stand out, because willpower must overcome instinct. Instinct is afraid of running, but willpower must rush forward. Instinct is lazy and afraid of pain, and willpower can even scrape the bones and heal the wounds without taking anesthetics...

Willpower must transcend instinct, not everyone can do it. Only by doing this can you control Qi.

"Everyone has qi in the body, and at the same time has inert yin energy and active yang energy. The body always experiences the yin energy of the yin at the end of the body, and the yin energy that stabilizes the body is constantly converted into yang energy, which represents the demise of life. Although people can replenish some yin energy through eating, replenishment cannot keep up with the consumption. However, after learning to control qi, they can control the yang energy released in the body and inhale the yang energy back into the body. Just like breathing, the exhaled qi is sucked back and for secondary use." Duran introduced the practice technique to the two human bodies.

"Do you know what this method of cultivation is called by sucking the qi back and using it again?"

The courtesan said: "When I was in Jiyuan, there are immortals in Dongda who can breathe without mouth and nose, but with the skin. This is called 'fetal breathing technique', just like a baby in the womb. The baby does not breathe with mouth and nose in the womb, so he got the name. Is the secondary use you mentioned is 'fetal breathing technique'?"

"It is worthy of being the courtesan of You Guo, and it has good knowledge. This is the fetal breathing technique." The brothel in the shogunate is called You Guo, and the fallen woman is called You Nu. Ji Yuan is the place name, and Ji Yuan You Guo is the brothel built in Ji Yuan.

The breathing technique in the womb, referred to as "fetal breathing technique", does not breathe with the mouth and nose, and obtains energy through the transformation of qi.

"Slow down the transformation speed of qi and extend your life. If you can really build a system of 'Collection of yang and yin' in your body, the body can exist independently of the natural system, which can be said to be immortal. However, this is difficult to do, because human computing power is not as good as nature, and yang is a natural phenomenon and has high efficiency. The artificial anode produces yin far less than that of yin, so you will die in the end. This is also the reason why external alchemy techniques appear, and external objects need to be used to make up for the lack of qi."

"I have heard of You Guo that there is another way to practice the cultivation of yin and nourish yang, which is to practice two people with one man and one woman." said the courtesan.

Dulan smiled and said, "I can see that this is how you practice, absorbing the man's qi to make up for your own losses. This is indeed a method of cultivation, a kind of art of room art, and it is actually an external alchemy technique, which cannot last long. Because the loss of the two of them is still greater than that of replenishing."

Why can the courtesan kill so many men? It is because she absorbs the essence of men and has mastered a strong power.

She continued: "I also heard that there is a method of cultivation called Zhou Tian, ​​but I don't know if it really exists."
