The world tree needs tree keepers. So when Tesla wanted to leave here and hand over the responsibility of tree guardian to new people, he started a series of procedures to let World Tree automatically select qualified people from it. There were many candidates who came to Tesla, and in the end, only three people were qualified to take advantage of it, and Alex was the third person. "Am I the third person?" Alex asked. "Yes!" "What happened to the two people in front?" "They proposed new ideas and development directions. Unfortunately, they could not develop in their infancy due to lack of energy or the energy cycle system. There are loopholes, and the power consumption is too great. Once it fails, the new branch will wither and die, and they will no longer exist in this world tree.¡± After listening to Tesla¡¯s words, Alex finally said. Understand, this is the moment of his life and death. Once he takes the wrong step, not only will he die, but the universe he is in will cease to exist. Alex put his hand on the trunk of the World Tree, closed his eyes and sank into his mind to sense the universe he was in. He immediately saw the inside of the entire tree, first he saw the branches and veins of the tree, and then he saw the tree's cells, and then saw the universe that makes up cells. According to the information obtained by eating the fruit, it can be known that every three thousand small universes surround one universe, every three thousand universes surround one large universe, and every three thousand large universes surround one ultimate universe, and every three thousand ultimate universes form A cell of the world tree. After locking onto the universe he was in, he saw people he was familiar with, including his parents, brothers and sisters, relatives and friends, and other people he knew and didn't know. They were all busy and living peacefully without knowing anything. "Have you thought it through?" Tesla asked softly next to him: "How can you find a way to make your universe develop different branches of civilization, which will then affect the world tree and continue to develop." "I've thought about it!" "Oh? What method?" "You are a tree protector, so you should know what the moon demon relies on to survive, right?" Alex closed his eyes tightly. His hands did not leave the trunk, and while observing the people on the earth, he explained to Tesla: "As species that have invaded the World Tree, they themselves cannot directly absorb the energy of the universe, but they can refine the raw materials and turn them into their own." The energy needed. Even a small part leaked out and became the source of mysterious power. Tesla touched his mustache and understood what Alex was talking about. He knew that the mysterious power referred to in that world actually came from the crystal energy contained in the moon. As for the crystals on the moon, they are actually the diamond-shaped crystals on the forehead of the Moon Demon. When the Moon Demon dies, he will leave the crystal behind. Every piece of crystal possesses huge energy, which was transformed by the moon demon when it devoured human souls during its lifetime. If you look at it from this perspective. Alex has indeed found a path, a path to endless energy. That is the human soul! The soul itself cannot be used directly as energy, but it can be used as raw material and processed into huge energy. Human reproduction is endless, and many people die and are born every year. If the soul can also be used as a source of energy, there will be no possibility of exhaustion. But there is still a big problem here, a huge problem! before this. It's not like no one has ever thought of using human souls as a source of energy. "Your idea is excellent, but I'm not very optimistic about it! You don't know, right? If you want to deeply process the soul and turn it into energy, you must have a very high-end utensil! Or it can be called a tool. When the Shinto civilization developed to the end, they could also directly process souls into energy, but that was only possible if they had the godhead." Tesla paced and said: "If you use Shinto methods to cultivate it. Godhead. Then your branch is no different from the Shinto branch. If you don't use Shinto methods, you will be stuck in the initial stage and it will be impossible to do it. To the extent of refining the soul. Even the branch of scientific and technological civilization I established has not reached this level so far!" Finally, he concluded: "So, your step is too big! ¡± Alex didn¡¯t appear to be panicked after hearing this. Instead, he smiled: "I also know that the beginning of any civilization is very important. If it cannot develop at the beginning, then no matter how beautiful the prospect is, it will be in vain. Just like technological civilization, it also needs oil, natural gas, and nuclear energy as a transition. It is possible to develop with these resources.It was originally buried. "Tesla nodded, acknowledging Alex's guess. "In the world before my rebirth, I once came into contact with a fantasy novel that described a civilization. This civilization is called rune technology. It looks very scientific, but it fails to explain where the energy of rune technology comes from. " The more Alex talked, the more excited he became. He said loudly: "I guess I vaguely guessed it until we got here! The energy of rune technology actually comes from human beings themselves, it is human spiritual power, or in other words, the soul is used as fuel! " When Tesla heard this, he couldn't help but said: "But you haven't yet been able to explain how to make human society go beyond the first few steps before it can have the energy to refine the soul! Alex opened his eyes, looked at Tesla and said with a half-smile: "Actually, you already know how to solve this problem, but you have never started to implement it. Instead, you want to wait for us candidates to think of it ourselves!" " "oh? how do I say this? "Tesla also smiled. He was really smiling. Someone finally understood the hint he left. After the development of technological civilization reached its peak, he was already thinking about how to develop next, but that At that time, he had already decided to break away from the relationship with the World Tree and relieve himself of the responsibility of "Tree Guardian". So after the candidate plan was carried out, he purposely interfered in the selection process, and all the candidates were included in it. Along the way, he will encounter content that he has set up to prompt these candidates to finally take a new path. He cannot tell the candidates directly, and the tips he gives are mostly vague. But even in this way, Not many people understood it. Fortunately, Alex reacted quickly. After entering this space, he kept thinking about Tesla's purpose and what Tesla would do. When doing tasks, There are always some clues. Whether it is a manuscript, a key code or other items, he carefully considers the meaning of these things. When everything is clearly displayed in front of him, one special thing becomes very noticeable. , that is the Moon Demon Diamond Crystal! With such a crystal in hand, Alex did not think it was obtained by chance, but that it had a special meaning. He and Valentina were able to travel through the first space. The second space relies on the energy of the Moon Demon Crystal. If every step he takes is set by Tesla, and the crystal is only used as a prop, there is no need to spend so much time to detect the Moon Demon. After discovering the special features of the crystal, Alex focused his mental energy on this crystal and began to carefully study its function. Soon, he came to a conclusion: "The crystal is used by the Moon Demon to refine human souls. Tool of! It is equivalent to the godhead, but it is not the godhead! " It is a semi-living substance! When the moon demon dies, the body will decay and return to heaven and earth, but the crystal stone can remain active because of its own special properties. It will continue to radiate mysterious energy outwards until it Until its own energy is exhausted. ¡°Spar! " Alex used his mind to control the crystal to float in front of the two of them. The crystal was emitting bursts of fluctuations. Originally, Alex couldn't see these fluctuations, but after he ate the fruit, he had He has a power that is comparable to that of a god. Whether it is divine power or magic, or forming formations or technology, there is no secret in his eyes. "It's good, you have discovered the effect of crystals. Tesla nodded in praise and said, "Then what are you going to do?" If you want to refine soul energy through crystal stones. You can try to design an energy circulation system and see if World Tree can accept it? " At this point, Tesla still did not reveal the mystery, but allowed Alex to explore and try. This attempt is not without cost. Every change made by Alex will touch the basic rules of the universe. Once the change is too big and the energy circulation system is defective, it will naturally be judged as failure. These key points were already very clear to Alex when he ate the fruit. It was simulated in his own mental space, trying to design a perfect energy circulation system. In the mental space, the crystal appeared in Alex's hand. Now Alex can project himself into the mental space and possess it. His own spiritual body, since eating the fruit, the spiritual space has received huge energy injection, forming a real space, a space as vast as a galaxy. In this space, he can be like the Creator. Things can create any object or life at will.?? As long as these things follow reasonable logical laws and there are no big loopholes in their own energy and material cycles, then they can truly exist. In order to practice his skills, Alex did not immediately modify the crystal stone, but looked into the distance. In his sight, fertile land appeared, and green life grew rapidly. Then the mountains rose, clouds and mist rose, and lightning appeared. Finally, various animals and plants appeared out of thin air, some of which looked similar to life on earth, while others were imaginary creatures. In a single thought, the time in the entire space seems to have been set forward by tens of millions of years, the earth and sky are changing rapidly, and life on the ground is evolving. All this takes place on a circular piece of land suspended in the void, with the sun, moon and stars revolving around it. "Well, I probably have mastered some skills!" Alex thought to himself. Things in the space took a long time, but for him, it was only a matter of a minute or two. "Let's see what this crystal does next!" He looked at the crystal in his hand. Under his gaze, the crystal gradually changed into a sparkling seed. A tangible and insubstantial seed, he flew into the sky, looking down at the saucer-shaped continent, looking for a suitable target. Finally, he chose an animal that looked smarter. With a snap of his fingers, the seed flew into the body of one of the animals. At this time, Tesla suddenly appeared in this space. He looked at the world with great interest and said: "It's a pretty good space. It seems that you have completely mastered your abilities." He paused and continued. : "But why did you turn that crystal into a seed?" Alex smiled slightly and said, "You will know after you read it!" After saying that, the time in the space passed quickly, and there were only two people. There is no change at all, they are like eternal existence. When a thought arises, thousands of mountains and rivers disappear; when a thought disappears, the sea changes. After countless eras, the animals implanted with seeds continued to reproduce. In the eyes of the two people, one seed turned into countless seeds, silently silent in the body of that animal. When one branch of this animal inadvertently received the stimulation of seeds and evolved into more advanced life, intelligent species appeared. A new kind of intelligent life rules this space. Each of them has a diamond-shaped crystal on their forehead, just like the moon demon, but they are not the moon demon. At first, like human beings, they passed from primitive society to slave society, and then entered feudal society and capitalist society. ¡°In this world, there is no oil and natural gas buried underneath, and they cannot use other energy sources to promote social development. Because Alex doesn't want them to be too biased towards technological civilization, whenever the social development trajectory deviates too far, he will intervene and bring down natural disasters to destroy the initially established sprouts of technological civilization. Several times in a row, it ended like this. When he saw this, Tesla frowned and said: "If you continue to develop like this, there is no way to obtain a large amount of soul materials to build the civilized society you want! Even if it is successfully established, it is just equivalent to copying. The social civilization of creatures like the Moon Demon, but you have no way to provide high-quality souls for them to develop!" Alex shook his head and said: "No! After these few experiments, I already know what to do! There is no need to devour the souls of other high-level beings to refine energy, they themselves have this energy!" As he spoke, Alex stretched out his finger, and one of the intelligent beings received a revelation and possessed some kind of cultivation skill! Law. After practicing, this kind of intelligent life has gained more powerful power. Not only that, their own souls have also changed.
