The earliest origin of the word Demon Gate can be traced back to the Warring States Period, when there was a name Yang Zhu who was competing with Mozi in the same generation, and his doctrine was considered to be contrary to Mozi, Mozi advocated both love and Yang Zhu advocated self-esteem. His doctrine and insights are scattered in the pre-Qin masterpieces such as "Liezi", "Zhuangzi", "Mencius", "Han Feizi", "Lü's Spring and Autumn", etc., in the Warring States Period, there was a phenomenon of "the doctrine of the world does not return to Yang, but to Mo", and its influence can be seen.

Then the world commented, on Yang Zhu's doctrine of the opinion is actually mixed, some people denounce it as heresy, some people regard it as a treasure book for governing the world, since the Han Dynasty Xianxue developed, gradually some people defined it as the doctrine of the Demon Gate. In many works, it has been said that Yang Zhu himself studied from the ancestors of Confucianism, Taoism and other schools, so in terms of doctrine, many of the ideas of the Demon Gate are actually very close to Taoism, and some people even think that the Demon Tao is a family.

Nowadays, there are very few people who follow orthodoxy, and they pick up a few words as a doctrine and put up a banner. For example, today's demonic flames are destroying the heavens and the earth, taking the righteousness of "people do not destroy the heavens and the earth for themselves", but it is the one-sidedness and extremism of Yang Zhu's theory. But there may be an opportunity to be in the body, the two masters of the Heaven and Earth Sect, the Heaven and Earth Sect Masters, the Heaven and Earth Sect Masters, each got an ancient book inheritance, and each practiced a set of magic skills, one is called "Heaven Punishment Blood Drawing Dafa", and the other is called "Earth Destruction Qi Extraction Tips". With the two major demon skills, the two of them were born under the siege of the righteous martial arts, and the results were quite impressive, and they also faintly regarded themselves as the number one faction in the demon gate.

For those who are a little more righteous, there is a happy life gate, based on Yang Zhugui's self-theory, saying: "The most precious person in his body is no more than life, life is difficult to meet and death is easy to reach, this short life, should be extremely precious, to be happy, everything is precious to save me, do not make him harmed, go and never come again." "This Leshengmen is based on a "Fidelity Canon" of martial arts, and its classics are all-encompassing, with swords, guns, sticks, and other eighteen kinds of martial arts practice methods, there are foundational internal skills, and there are exercises to refine the body. I haven't seen much evil in this sect, but I live in the rivers and lakes but I take your self as righteousness, ignore the righteousness of the rivers and lakes, and indulge in lust all day long, which is mostly despised by the righteous sect. Therefore, it is defined as the way of the devil because of its teachings, not its style of conduct. In this way, in Lu Yuan's opinion, he is quite willing to associate with the people of Leshengmen.

The other takes the door of the teachings of the Yang Zhu school called the door of prudence and goodness, and covers the words of Yang Zhu recorded in the "Liezi": "Do good deeds do not take the name and follow it, the name does not return to it with the hope of profit, and the benefit does not fight for it, so the gentleman must be cautious and good." "The door of prudence and goodness is taken from the last "gentleman must be cautious and good", but it is upheld that "those who are not profitable, there is no goodness." Those who are advantageous and contentious, and those who are advantageous do not do it. Those who are righteous and famous, although they have fame and fortune, do not do it. "It's nothing, and it seems to be quite in line with Yang Zhu's teachings, but ...... This sentence does not mention whether it is evil or not, so they still hold half of the doctrine that says: "If there is evil to do, there is no benefit." Those who strive for profit and evil will also fight for it. Those who disregard righteousness and ruin their reputation, even if they have no fame or fortune. "With such a doctrine, it's hard not to enter the Demon Gate. However, although the Shenshan Sect is called a sect, it has not seen the town sect exercises, and the thieves from all walks of life on the rivers and lakes can enter the sect if they obey the dispatch, and the composition is quite messy, and it is also the most lax management faction in the Demon Gate.

These three families were originally divided into demon sects, and later split up due to disagreement, but nominally they still obeyed the orders of the Demon Cloud Mountain General Altar Holy Sect. And the Demon Cloud Mountain is also the place of the contemporary Holy Monarch and the ancestral court of the Demon Gate, adhering to all the teachings of the Yang Zhu School, but the General Altar Holy Sect has a town school exercise, called "Returning to the Same Anti-One Absolute", which is the "Jue" of "Killing", not the "Trick" of "Formula", which means that this is a technique that contains the "Kill" technique. It is rumored that the world has seen this "absolute" survivor, but no. So, no one really knows what this trick is. This peerless past generations only passed on the Holy Monarch, and even the Holy Son of the Imperial Book was not qualified to see one or two of them.

This is the situation of today's Demon Gate, one altar and three sects, the main altar holy sect is nominally the head of the demon gate, but in fact, the three religions go their own way, and the heaven and earth destroy the door and faintly regard themselves as the head of the devil, and often do not take the general altar order seriously. The strange thing is that the general altar also turned a blind eye to this, which made many righteous sects in the Bawang Demon Sect confused. In addition, there is the so-called Houjinmen, because it is the legacy of the Jurchen remnants, so it is also classified into the Demon Gate, but it is not recognized by the Demon Gate, and acts evil martial arts righteousness, was strangled by the righteous sects, and can not be neutral, the situation can be described as very embarrassing, can only fight alone, hanging overseas.

It is said that the three sects of the Demon Sect plus one alien force are only five sects, which is pitifully small compared to the four sects, six families and eight major sects of the Righteous Path combined with the eighteen sects, as long as the Righteous Path sect unites to exterminate it, it should not be too difficult, but it is still allowed to exist, if it was before, Lu Yuan may not understand why. Now that I have calculated the power and situation of the Eighteen Righteous Path Schools, I understand it in an instant. The eighteen sects look like a lot, but it's just a plate of scattered sand, and they are pinning their hopes on the civil strife in the Demon Gate, so they naturally have the idea of sitting back and enjoying their success. The Demon Gate seems to be in decline, but the strength of each door is very strong, just that day to destroy the door, it is impossible to say that one of the Shaolin or Wudang factions will be dragged by it, not to mention the other sects, who is on who dies, no one wants to be this bird, so they have to be so anxious about each other.

But these are just superficial representations, don't say what the situation inside the Demon Gate is, the relationship on the side of the righteous path alone is intricate, and it is difficult to sort it out in a short period of time. The so-called rabble is actually the best explanation for the current situation of the righteous path, not that the various factions are incapacitated, but that they can't do things together at all, let alone such a major thing as destroying the demon gate.

And the inside of the Demon Gate does not seem to be as simple as it seems now, because there is a common enemy, once there is a major move on the side of the righteous path, I believe that the group of madmen in the Houjinmen will not mind taking the opportunity to stab the righteous path in the back. In terms of the four sects of the Demon Dao, it is certain that the Holy Sect of the General Altar is definitely not as weak as it appears now, or maybe the strength of the Heaven and Earth Sect and the discord between the General Altar are just deliberately shown by them, and now that they are involved in this way, it is impossible for the righteous path to act rashly.

In short, the current situation of good and evil is very delicate, but it is at a balance point, which is really uncomfortable to watch. But the rivers and lakes are like this, there is no conflict of interests, where is the real rivers and lakes?
