He Shouyuan was even more surprised, and said, "He, an immortal, I don't think it's possible." I'll have to ask him when he comes back. Then he said, "Uncle Huang, tell me the story of the people in that world." ”

Besides, Yun returned to a certain university, and looked at the progress of Wei Pu and Chen Fengya in the past few days. Chen Fengya was originally in the innate realm, but his cultivation speed in the future was not very fast. Now the cultivation of the two is basically the same. When the two saw that Yun Chong was back, they hurriedly greeted him, and asked Yun Chong for answers to the incomprehensions they had encountered when they had been cultivating in the past few days. Their questions are often a bit ridiculous, but they are inspiring. After answering all of these questions one by one, Yun Chong also returned to the back mountain and began to cultivate. No matter how high you cultivate, cultivation is essential.

Now Yun Zhong has Ge Hong's alchemy experience and Ou Yezi's refining experience, which can be said to be a double harvest. He must take advantage of this time to digest these things well, otherwise it will be someone else's after all.

Yun Zhongzi's jade slip also has the experience of alchemy, and the method used by Yun Chong for alchemy before is recorded in it. But compared to Ge Hong's experience, it is simply chicken ribs. Ge Hong is the best at alchemy, and in the Three Realms, in addition to the alchemy patriarch Taishang Laojun, his face skills are the most powerful. The experience he left behind can be imagined, and it must be a rare alchemy treasure.

Yun Zhong read through Ge Hong's alchemy experience and felt that he had benefited a lot. Alchemy is not only about bringing out the essence of the medicine, but also about adding the aura of heaven and earth to the elixir, so as to improve the efficacy of the elixir. Although Yun Zhong also vaguely felt this, it was not as clear as it is now.

But how can we accumulate the spiritual energy of heaven and earth in the elixir? Is there a place to store the spiritual energy in the elixir? Thinking of this, Yun Zhong took out the most proud elixir he had refined, the Buzhong Yiqi Pill, and carefully observed it. This time, he directly transported the power of his whole body to his eyes slowly, and in an instant, Yun Chong's eyes turned into two Tai Chi patterns, constantly rotating with the operation of his power.

With the gradual injection of power, Yun Zhong once entered the realm of the last time. The serious elixir gradually became clear, and finally every molecule of it became clear. Yun Zhong saw that the structure of the pill was mostly a cylinder with a hexagonal shape as the bottom edge, and there was a large atom in the middle of the cylinder, and there was an atom at each vertex above and below. Each cylinder is made up of thirteen atoms. This is a close-packed hexagonal structure.

Yun Zhong carefully observed the arrangement of the thirteen atoms, and suddenly his heart jumped. Twelve atoms, and one in the middle, isn't this a super small zodiac spirit gathering array? The large atom in the middle is the eye of the array, and the other twelve atoms are different, representing the twelve zodiac signs. Yun Zhong looked at the other bars and found that they were all very similar. The difference is the arrangement of the twelve atoms.

Yun Zhong also found that all the atoms in this small spirit gathering array could only see a faint stream surging, and the thin stream continued to flow, but it never flowed outside the cylinder. Could it be that this is what is formed after the accumulation of spiritual energy? So what exactly are these auras? Are they matter or energy? Do they have mass?

In order to answer this question for himself, Yun Zhong slowly injected his true essence into the elixir. Through the guidance of the true element, he gradually absorbed all the trickles in the body of the column, and finally entered his own meridians. When the trickle in the last column was absorbed, Yun Zhong sensed that the weight of the pill seemed to be a little less. If this trickle really has mass, then it must be a substance. But why does it exist in the form of a pure energy body? How is it possible that all scientists have not detected the existence of such a substance?

Rich in energy without being discovered, this couldn't help but make a substance flash through Yun Chong's mind. That substance exists outside of what is known to man, and people currently know that it exists, but they don't know what it is, and that its composition is different from what is known to man. In the universe, the energy of that matter is many times greater than the energy of matter known to man. That's dark-matter-substance!

This astonishing discovery made Yun Chong overwhelmed for a while. Humans have been proving for years what dark matter really is, and why is it possible to theoretically prove their existence without finding a trace of it? If dark matter is Reiki, then everything can be explained now. In ancient times, for some unknown reason, the infinite leakage of spiritual energy on the earth caused the entry of cultivators slowly. But fortunately, there is still some aura left, but this amount of aura cannot be detected by the current scientific instruments at all. Only cultivators can feel the existence of dark matter through themselves as the furnace.

Yun rethought: There is not much dark matter on the earth, that is, aura, but there should not be too little aura in space. Then why don't I arrange a huge spirit gathering array in space to attract the aura from space to the earth, wouldn't this be a good thing for the benefit of all generations. But the space is dangerous and abnormal, and even though the cultivators are strong, they don't dare to fly out of the earth easily. Although Yun Zhong thinks he has some skills, he doesn't think that he can already travel in space. If nothing else, let's just say that the vastness of space is a problem. If you want to arrange a spirit gathering array in space, it must be a star. Where will the weight of the stars be light, so this matter can only be said later.
