According to the old people's mouth, one yin and one yang is the way. Everything is made up of yin and yang, the sky is yang, the earth is yin, men are yang, women are yin, day is yang, night is yin, and so on. The universe is divided into three realms, namely, heaven, earth, and hell. Human beings have souls, everyone has three souls and seven spirits, and if there is no practice, living beings will die. After death, you have to report to the underworld, where you will be judged by the king of Yama, and the judgment will be made according to the performance of each person in the yang world, and according to the judgment of reincarnation.

The underworld is the place where the lives of all living beings are in charge. All things in heaven and earth, after death, their souls are bound to the netherworld by black and white, and all their good and evil in the yang world must be ended here. As the saying goes, the living are in the yang, the dead are in the underworld, the yang is a world, and the underworld is a world. The world says that the underworld is eerie and terrifying, and there are lonely souls and wild ghosts everywhere. In fact, who has seen it with their own eyes, it is called a world, there is beauty and ugliness, this is the case in the yang world, and the same is true in the underworld.

Legend has it that the underworld is also a world, with a systematic structure and the rule of power. The highest-ranking Emperor of Tianqi Rensheng is in charge of all living beings on the earth. Then there was the Emperor of the Northern Yin Dynasty, and then there were five ghost emperors: the Eastern Ghost Emperor Cai Yulei and Shen Tu, who governed the "Taozhi Mountain" ghost gate; Western ghost emperor Zhao Wenhe, Wang Zhenren, ruled "Lingzun Mountain"; Northern ghost emperors Zhang Heng and Yang Yun, governing Luo Yu Mountain; Du Ziren, the ghost emperor of the south, ruled Luofu Mountain; The central ghost emperor Zhou Qi and Ji Kang governed the "Hug Calf Mountain"; Below is the six days of Luo Yu (the following is the name of the palace, and the six days are the god of guarding the palace); The Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace, the Heavenly Palace.

Jin Kang originally didn't believe in ghosts and gods, but after he apprenticed to Tianji Daoist and saw Zhang Xiangling, he believed that ghosts and gods existed objectively, but there were differences with legends. Jin Kang once asked the master. The master explained that the underworld turned out to be a bit similar to the legend. According to his own understanding, the Tianji Daoist described it to Jin Kang.

The Heavenly Machines Daoist believes that people do have three souls and seven spirits, but the vast majority of people die like a lamp going out, and after death, the soul becomes pure energy and dissipates in heaven and earth. However, encountering a spirit with resentment and a strong reluctance to die may form a resentful spirit, which will not dissipate for a long time, resulting in various supernatural situations. Nowadays, cremation is prevalent, and the body that has lost its sustenance cannot be maintained for a long time, unless there is a method of cultivation and cultivation. However, the Tianji Taoist also believes that if you cultivate to a certain realm, you can keep the original spirit from dispersing and can be reincarnated. Therefore, cultivators can theoretically be reincarnated, and of course, it is not excluded that some people also happen to have the opportunity to be reborn into a new life with the consciousness of their previous lives. Therefore, there are reports in the world from time to time that so-and-so has memories of a past life. The Tianji Daoist believes that the underworld should exist, but there should not be many creatures in it, which may be equivalent to a transit station, and the function of the underworld should be to balance yin and yang.

Jin Kang felt that there was some truth in the master's words, but it was difficult to describe it clearly without going to it.

Soon it was the seventh and a half months, the Midyear Festival. Zhongyuan Festival is the name of Taoism, and the folk secular is called the Ancestor Worship Festival on the 14th of July and the 14th of July (the other says the 15th of July), and the Buddhist name is the Obon Festival. The festival customs mainly include worshipping ancestors, releasing river lanterns, worshipping the souls of the dead, burning paper ingots, sacrificing land, etc. On this night, local residents routinely burn paper money and offer tribute to their ancestors. Jin Kang returned to the Zhiguan and found that Zhang Xiangling was about to go out. Jin Kang is very strange, Zhang Xiangling rarely goes out at night, except for accompanying Jin Kang. Jin Kang asked Zhang Xiangling what he was doing, and Zhang Xiangling said to gather incense. At this time, Jin Kang became even more curious. Jin Kang asked, isn't it for the ancestors to burn paper money? Zhang Xiangling smiled faintly and explained that when most people's ancestors died, their souls disappeared into heaven and earth, and there was no connection with the world for a long time. People burn paper money just to mourn and remember their ancestors. Zhang Xiangling explained that burning paper money has the power of faith and can help in spiritual practice. Jin Kang couldn't figure it out, and faintly felt that something was wrong. Zhang Xiangling went out.

After a while, Zhang Xiangling came back with a panicked expression. Jin Kang looked at it and knew that something big was not good. Sure enough, Zhang Xiangling said that he had met an envoy from the underworld and was chasing after him. As soon as the words fell, two dignified men appeared, showing righteousness between their gestures, but faintly exuding an eerie atmosphere, feeling a little cold.

The man who came in first spoke "Zhang Xiangling, you have violated the law." Zhang Xiangling seemed to be in a loss and did not speak. Jin Kang greeted him with a smile, and immediately ordered Zhang Xiangling to pour tea and ask the two messengers to sit down.

It turns out that the Yin God rarely exists in the world. One is that the yin god is rarely formed, and the other is that the underworld is strictly managed. According to the explanation of the two messengers, during the Midyear Festival, the sun sacrifices to the ancestors, and the power of the underworld comes out to walk according to the divided territory. The great powers of the underworld, who were human beings in their previous lives, are only successful in cultivating and transcending reincarnation, one is to go out to see their own descendants, the other is to clean up the grievances, and more importantly, to enjoy the power of faith. The power of faith can increase the cultivation of the mighty. Yin gods like Zhang Xiangling have not yet achieved cultivation, so they can only take the initiative to report to the underworld, practice in the underworld, and after the cultivation is completed, they will be promoted to ghosts and immortals, and become powerful step by step, and they will be in charge of one side. There is always a difference between yin and yang. The underworld does not allow the Yin God to stay in the world for a long time, and even the resentful spirit can stay in the world for a year at most. Every year during the Midyear Festival, all parties will dispose of the yin gods and resentful spirits that linger in the world. The spirits generally take the method of cleaning up, exceeding, and letting them dissipate between heaven and earth. The Yin God generally takes Zhao'an, leads the underworld, and settles a cultivation cave for him, so that he can practice with peace of mind.

Zhang Xiangling's situation is relatively rare, she has been in the world for many years, and there has been no envoy from the prefecture to find her. Because she is the spirit of other beings, she first practiced, and then failed to become a yin god, because she was contaminated with the thunder of the heavenly tribulation, and it was difficult for the general underworld to sense, so the underworld did not know her existence. This encounter was because Zhang Xiangling enjoyed the power of faith on the street of the Midyear Festival without authorization, and enjoyed it privately, which belonged to the taboo of the prefecture, and it was only when the envoy of the prefecture sent a parade that he discovered Zhang Xiangling's abnormality.

Jin Kang took the initiative to shake hands with the two messengers and say hello, only to see that the two messengers looked nervous and unconsciously retreated. Jin Kang explained that he had no ill intentions. The two messengers hurriedly said respectfully, "Your Excellency is a person who has attained the Dao, and his yang energy is vigorous, so we dare not offend and approach, please keep your distance from us." It turned out that the envoys of the underworld could not approach Jin Kang, and the yang energy on Jin Kang's body would hurt them. Jin Kang smiled smugly, and then asked the messenger. Does the prefectural government have any regulations on how to punish Zhang Xiangling for such violations? The envoy of the prefecture said that there was no explicit provision, and then explained that he was just catching up to understand the situation, to see if Zhang Xiangling had harmed the world, and the most important thing was to lead Zhang Xiangling back to the prefecture to settle. According to the supervision records of the prefecture, Zhang Xiangling has never harmed living beings, and is a kind Yin God and Ghost Cultivator. Zhang Xiangling immediately refused to go to the underworld to practice, saying that he would definitely abide by the rules of the underworld and not cause harm to the world. Jin Kang expressed his willingness to use his Dao heart as a guarantee to ensure that Zhang Xiangling is kind to others. Zhang Xiangling was excited. Seeing that there was nothing to do, the envoy of the prefecture said goodbye and left, and before leaving, he still told Zhang Xiangling that the power of faith could not be enjoyed without authorization.

As soon as the envoy of the underworld left, the Heavenly Machine Daoist appeared. As soon as he sensed that there was something abnormal in the Zhiguan, the Tianji Daoist came, for fear that his apprentice would suffer. Seeing that the two underworld envoys did not embarrass Jin Kang, the Tianji Daoist did not show up. Jin Kang felt that it must be that the envoy of the underworld also sensed the existence of high-ranking people around, so he was very polite to Jin Kang. The Tianji Daoist told Zhang Xiangling that returning to the underworld to practice would have many benefits, and he hoped that Zhang Xiangling would consider it. Zhang Xiangling looked at Jin Kang for a long time and was silent, Jin Kang knew that Zhang Xiangling was reluctant to leave him. Jin Kang and Zhang Xiangling got along and became confidants and didn't want to leave each other. However, Jin Kang and Zhang Xiangling are not ordinary lovers, and the two are more like relatives.

Jin Kang pondered for a long time, whether it is a person or a living being, it seems that he needs to practice in order to live forever, otherwise he has been in the world, and there is no past life and no future.
