The feeling of being noticed was very weird, Zheng Fangming knew that he was cleaning up these remnants of mental power in a state of an outsider, and there would be no intersection with the ghosts and events in the remnants of mental power, but he still felt that he was noticed by the strange ghosts in front of the store, although the strange ghosts were very secretive.

Zheng Fang deliberately stopped the transformation work, he wanted to wait for the end of this picture of spiritual power, he wanted to feel it again, to confirm whether the ghost was paying attention to himself, but unexpectedly, the content of this piece of spiritual power fragments was terrifying, and the strange ghosts celebrating on the street seemed to have no end, Zheng Fang waited for a while, and saw that it was not a solution, and he was afraid that he would be polluted after staying for a long time, so he had to retransform, but most of his attention was still resting on the black-robed ghost.

Zheng Fangzheng was transforming, and suddenly saw the strange ghost on the opposite side glance at him again, then turned around, blended into the group of strange ghosts on the street, and disappeared in an instant. Zheng Fang was almost immediately sure that the strange ghost was looking at him, and for a while, he only felt a cold air coming out of his head, what was the matter with this strange ghost?

Zheng Fang ended the transformation of this piece of spiritual power residue, and found that the spiritual power residue in the partition had been cleaned up, and then cleaned up a few pieces of newly floating debris from the transit room, Principal Huang decisively terminated today's cleaning work, today is less than yesterday's clearing, only more than 400 pieces, Principal Huang is planning to enter the transfer room tomorrow? Zheng Fang had something in his heart, and did not insist on continuing to clean up, and left the spider's mouth with Principal Huang.

Along the way, Zheng Fang opened his mouth several times, wanting to talk to Principal Huang about the strange ghost, but in the end, he gave up, and he could almost guess Principal Huang's answer: You feel that something must be wrong, that strange ghost must be looking at something else. If Zheng persists, Principal Huang may even wonder if he is contaminated. This feeling Zheng Fang himself felt incredible, where did he have the confidence to convince others, and maybe he really felt that something was wrong, Zheng Fang thought so, did not ask again, but said goodbye to Principal Huang and went back to his dormitory.

I didn't say anything all night, and continued to study the next day, and the teacher who came in the first session in the afternoon was still Liu Xiangyang. He came to the classroom, first drew a huge circle on the blackboard, then drew an arc with two curved ends in the middle of the circle, then drew two small circles on each of the two curved parts, and then painted half of them with chalk, and when he was done, he turned around and looked at Zheng Fang.

"It's a Tai Chi pattern, and the Taoists use this pattern to explain the world we live in, and we use it to explain the Three Realms. Liu Xiangyang said: "This white fish symbolizes yang, that is, our human world. This black fish symbolizes yin, which is what we often call the underworld, and this line between yin and yang has the effect of regulating yin and yang and communicating the two worlds, and this line is what we call the spiritual world. ”

"The theory of the spiritual world began in the pre-Qin period, and is mentioned in Taoist classics and Western mythology, but the formulation is different. We now believe that for a long time before the pre-Qin period, the three worlds of man, spirit, and underworld should be in a state of harmonious symbiosis, and the ascension of immortals refers to the success of human cultivation and the spiritualization of the physical body, so that they can enter the spiritual world relatively easily, and the so-called gods and immortals descend to the earth refers to the people of the spiritual world entering our human world. Liu Xiangyang opened the textbook in his hand as he spoke.

"The interconnection of the three worlds is the basis of the existence of the three worlds, after the death of human beings in the human world, the physical body will remain and nourish the human world, and the soul will be divided into two, the one soul corresponding to the living body and the four spirits will enter the underworld, and the two souls and three spirits corresponding to the vitality will enter the spiritual world. Some of these powerful souls will remain as the basic unit of life at the interface they reach and become the source of some powerful creatures in their respective interfaces, while most of the souls will be decomposed into soul power and yang power to become the components of the underworld and the spirit world, constituting the foundation of the existence of the two worlds and the nourishment for the development of creatures. In the same way, after the death of creatures in the underworld and the spirit world, there will also be a part of it that flows into our human world, and we call these two parts of the inflow yin qi and spiritual energy. ”

"I will elaborate on the other details of the interconnection of the Three Realms in future courses, but now I will mainly briefly talk about the respective characteristics of the Three Realms. "Liu Xiangyang said" To put it simply, the Yang Qi of the Three Realms is provided by the Human World, so the number and strength of the Yang Qi of the Three Realms depend on the Human World, while the Yin Qi of the Three Realms is provided by the Underworld, so the number and strength of the Yin Qi of the Three Realms are determined by the Underworld, and finally the Spiritual Qi of the Three Realms is provided by the Spiritual Realm, so the number and strength of the intelligent creatures of the Three Realms are determined by the Spiritual Realm. Understanding these three points is very important for us to understand the spiritual world. ”

Liu Xiangyang looked at Zheng Fangdao: "Recently, some people have been saying that our world is yin and yang is declining, although the people who say it are jokes summed up from the appearance, but it is undeniable that our human world is indeed in a more serious yin and yang decline, you know, our human world determines the amount of yang in the three worlds, and now, even the human world itself is yin and yang is declining, so it can be seen that the entire three worlds are in an imbalance, and we believe that this imbalance is the root cause of our bad relationship with the spiritual world today." ”

"Regarding the reasons for the yin and yang decline of the human world, we analyze two, one is the main source of yang energy in our human world," Liu Xiangyang stretched out his hand and pointed to the sun outside the classroom window, "The sun, since the two Han periods, has been in a low ebb period of the great cosmic cycle, which has led to the total amount of yang energy absorbed by our human world gradually decreasing compared with the pre-Qin period, and even less in the future, it is said that there will be a Xiaoice period in a hundred years, and then it can gradually increase." The second is that there is a problem with the channel of the Three Realms, to put it simply, our human world has been at the point of making ends meet, and the yang energy has gone out, but the corresponding spiritual power is insufficient, resulting in the absorption of yang energy in the human world now, and a large amount of yang energy is wasted. ”

"We think that before the pre-Qin, the passage of the Three Realms was open, from the perspective of our human world, before the pre-Qin, there were many legends of human beings who had achieved success in cultivation and ascended to the spiritual realm, but after the pre-Qin, this kind of legend began to decrease rapidly, and it is no longer heard of anymore. And the legend that the spirit world and the underworld entered the human world is also the same, before the pre-Qin period, it was very common for spirit creatures and underworld creatures to enter the human world, both in China and abroad, leaving many examples. These spiritual and underworld creatures entered the human world, or lived in seclusion, or participated in the war of the human world, but on the whole, they still have good intentions towards the human world, and the human world has touted the visitors from the above two worlds, but in general, they still regard it as the main thing, and do not think that those so-called gods and immortals are much more noble than themselves, but things have changed rapidly since the two Han Dynasty. ”

"We believe that this change is reflected in three aspects: 1. The passage has gradually evolved from two-way to one-way, and the number of cases of our human world entering the other two realms has decreased year by year, and there has been no case in the past three hundred years, the difficulty of human cultivation has greatly increased, and the spiritual power of the human world has become thinner and thinner. 2. Human beings have become more and more respectful of the visitors from the two worlds, especially those from the spiritual realm. The most recent example is that in the Ming Dynasty, the temple of the heavenly general and the hall of the patriarch were built in the forbidden city for a spiritual visitor surnamed Wang, and the hobby of this spiritual official surnamed Wang was to devour human virgins and virgins. Moreover, since the Song Dynasty, Taoist temples have also built Lingguan Hall as part of the overall building to enjoy the incense of the human world. 3. The attitude of visitors from the two worlds, especially those from the spirit world, towards the human world has gradually deteriorated from goodwill to the present day, with the purpose of slaughtering human beings to gain vitality. ”

"We guess that this kind of change is inseparable from the blockage of the Three Realms Channel. Since the Han Dynasty and the Han Dynasty, practitioners have regarded seeing spiritual creatures as a great opportunity, and there are many examples of cultivators becoming immortals and ascending because of the spiritual officials' teachings, but as time goes by, these examples have become fewer and fewer, and now there is no one to hear. On the other hand, there were many cases of visitors from the Two Realms slaughtering human beings and collecting souls, but in the early stage, in general, the visitors from the Two Realms still had good intentions towards human cultivators, and they did not hesitate to help them in some cases. However, in the past hundred years, the slaughter of human beings by visitors from the two worlds, especially from the spirit world, has become the mainstream, and in the war of aggression against China by the Dwarf Kingdom, our Chinese cultivation community has been forced to classify the visitors from the spirit world as enemies. ”

Speaking of this, Liu Xiangyang raised his head and looked at Zheng Fang seriously: "I want to emphasize here that the attitude towards the spiritual world is inconsistent in all countries today, and our country is resolutely fighting the main battle, but some countries still have illusions about the spiritual world, such as the country of dwarfs, etc., the attitude towards the spiritual world is very ambiguous, and the cultivation world has its own opinions, and it is difficult to reach an agreement. ”

"We guess that about 2,000 years ago, there was a far-reaching event in the Three Realms, which caused the spiritual power of the spiritual world to enter the human world was blocked, but at that time, the spiritual power of the human world was still abundant, and the feeling was not obvious, but in the past 2,000 years, the spiritual power of the human world has become less and less, and finally it has reached the era of the end of the law, where yin and yang are declining, the environment is deteriorating, and species are extinct. Although there is the influence of modern industry, the aura is not strong, and the evolution of human beings cannot be carried out, so they have to resort to strange tricks and tricks, which cannot but be said to be the extremely bad consequence of the blockage of the Three Realms Channel. ”

Liu Xiangyang continued: "The passage of the Three Realms has been blocked, and the human world has suffered greatly, but the spiritual world and the underworld have also been affected. Therefore, for thousands of years, not only have the great powers of the human world been constantly looking for ways to communicate with the spiritual world, but there are also a group of great powers in the spiritual world who have diligently sought to open up the channel with the human world. It's just that the human world is becoming more and more difficult to cultivate because of the scarcity of spiritual power, except for a very small number of hidden sects that still retain cultivation methods, most of the others have been lost in time with the passage of time. Up to now, only the spirit world knows how to open the passage with the human world, which is what we call the boundary gate, and no one in the human world knows about it, and no one has the ability to open the boundary gate. ”

Liu Xiangyang said: "When human beings die normally, the two souls of heaven and earth return to their positions, which will lead to the natural opening of the Three Realms Channel, guiding the souls to enter the two realms of spirit and underworld. However, human beings die unnaturally, the two souls of heaven and earth cannot return to their positions on time and normally, and the passage of the Three Realms cannot be opened immediately, so the souls of the deceased will stay in the human world for a long time, which is also the reason why many battlefields of great wars and murders have their own gloomy atmosphere. We speculate that the opening of the gate of the realm has given the spirit creatures the opportunity to quickly seize the vital resources of the spirit world, such as the life force of those who have died, and then from the dead to the living, inducing the greed and slaughter of human beings in the spirit world. Just as spiritual power can be obtained more for humans, it is impossible for spiritual beings to refuse this temptation. ”
