"Originally, the Taiyin Refining Technique was a strategy adopted by cultivators who failed to completely refine their physical bodies, and were unwilling to be autopsy, reincarnate or take away, and wanted to retain their existing physical bodies and continue to cultivate in the future. After death, it is refined underground. The corpse will gradually decay, leaving only the skeleton and the five internal organs, which will be guarded with true intentions, and then the body will grow again. The scriptures say: If it is not for the autopsy, those who die through the Taiyin and temporarily pass the three senses, the flesh is lost and scattered, the blood is gray and rotten, and the five internal organs are self-generated, the bones are like jade, the seven spirits are in the camp, and the three souls guard the house, or thirty years, twenty years, ten years, three years, when the flesh and blood are regenerated and reinstated, they will be better than those who have not died in the past, this name is refined. Taiyin is easy to look at, and the immortals of the three officials are also. ”

"Shangqing Nine Truths in the Inner Scripture" cloud: Mrs. self-cultivation in the nine truths, the body has not been promoted, the scenery shows customs, temporarily enters the Taiyin, the body is through the three officials, and the three officials are not allowed to be taken. Then the nine true summon souls, the Taiyi guarding the remains, the three-element protective qi, and the Taishang soul. Flesh and blood are immortal, and the five organs are immortal. It can die and live, and it can be yin and yang. Out of the void and into nothing, heaven and earth are born. It is the Taoist priest's quiet camp form, and he feels the qi of the nine truths. In this way, the flesh and bones can always be immortalized, the five internal organs will not fall, and finally the dead can be resurrected. This method is the most difficult in the Taiyin refining technique, and there is a poem that praises 'Taiyin refining the body, and winning the Nine Turns Dan.' The description is dignified and strict, the face is like a spiritual cloud, and he is a real person who ascends to Taijique, and receives the book. ’”

Mu Sheng listened to the new Taiyin refining technique, and suddenly his heart trembled, the "No Death Dao Method" he cultivated seemed to be faintly related to this Taiyin refining technique, and every time he succeeded in crossing the catastrophe, it was no different from the dead bones and heavy skin growth. I couldn't help but ask in surprise, "Is this Taiyin Refining Technique also taught to you by the Corpse Ancestor?"

Tan Taixin shook his head, sighed and said: "Where does the corpse ancestor have the spare work to teach us, it was the eldest lady who heard it from the corpse ancestor and recorded it in the book, I saw it." It's just that now the Taiyin refining technique is not complete, and it has been modified according to the actual situation of the dry corpse and the flesh corpse in the Soul Continent, so the secret techniques of the exercises are different. After all, it is difficult to ensure that before death, you can still ensure that you will not be distracted, do not enter the reincarnation and persist in cultivating, not to mention not being disturbed for three or twenty years, even if you are not disturbed by others for two years!"

Mu Shengxin said: "In this way, the book of "No Death Dao Law" that I cultivated seems to be a relatively complete version of the ancient preservation technique. ”

Thinking so in his heart, he asked in his mouth: "So only your corpse ancestor is the most primitive Taiyin Refining Technique?"

Tan Taixin frowned and thought for a while: "I don't know very well, but the story of the corpse ancestor is a bit peculiar." ”

"Oh, how peculiar, let's hear it?" asked Mu Sheng's gossip heart.

Corpse ancestor in ancient times, there is also a name, called Zhao Chengzi, under the tutelage of Nanyue Mrs. Wei Huacun, the corpse ancestor has been particularly smart since childhood, the teacher explained the way of practice, he is always the first to understand, first learned the "Huang Ting Jing", and then refined into the "Zhensheng Five Organs Sutra", but the internal cultivation was successful, Zhao Chengzi's external cultivation was not very smooth, because he was weak and sick since he was a child, he lost weight, and he had no power to tie the chicken, others copied the "Huang Ting Jing", the fastest hour, he had to copy a day.

When Zhao Chengzi was learning art, he was good at using his brain to meditate, but if he chopped wood and carried water, or even learned some physical skills, he was finished, his body bones were like sugar cane, and he looked black and ugly, and the brothers around him were jealous of his ability, and secondly, they despised his physique, and bullied him every once in a while.

Zhao Chengzi is introverted and not good at words, and others bully him. Born with a thin physique, the brothers around him are all dragons and phoenixes, and under the inferiority complex, he doesn't dare to say anything when he encounters things, and he has been trapped in a strange circle of self-denial for a long time, bullying and slandering from the outside world, and is powerless to resist.

At first, Zhao Chengzi had a few friends in front of him, but later I learned that these "friends" were with him because they were with him to make fun of him, and even the main helper of "Taoist bullying".

However, due to the majesty of Master Wei Huacun, these people didn't dare to go too far, and only dared to make a little bad behind their backs, and later Wei Huacun devoted himself to seeking the Tao, spending more time on retreat and travel, and often not in the Tree of Life, and the Ladder Immortal Kingdom, these people began to intensify, and even almost used Zhao Chengzi as a medicine a few times.

No matter how soft Zhao Chengzi's temper is, he can't continue to cultivate at this time, this cultivation is originally to ask for an immortality, but he didn't ask for immortality, and he can't die a death, Zhao Chengzi thought of this and asked his master Wei Huacun to resign.

It's just that at that time, Wei Huacun had already begun to take the Immortal Golden Pill, and he didn't see anyone in retreat, and Zhao Chengzi saw that the master was in retreat, so he meditated on the futon at the door and waited for the master to come out.

On the seventh day of Zhao Chengzi's meditation, Wei Huacun called him into the house and said, "I know what happened to you, do you understand the reason why you don't care?"

Zhao Chengzi said reverently: "I understand, the master naturally has the master's considerations, and the apprentice only regards this as a red dust refining heart." ”

Wei Huacun shook his head and said, "If it's refining your heart, why do you want to give up halfway?"

Zhao Chengzi was a little ashamed and said: "The apprentice has followed the master to learn the Tao since he was a child, and he is nothing more than seeking an immortal life, and now he can't even live for decades, so how can he seek immortality?"

Wei Huacun listened, and was silent for a long time before saying: "Since you are leaving, I will not keep you, come, master and apprentice, I will give you a secret book." ”

After Zhao Chengzi got the secret, he bowed down and returned home to study day and night, hoping to understand the meaning of his teacher. But who knew that at this time, the Heavenly Demon invaded the world and was in chaos, the situation changed for a while, Kyushu was turbulent, and there was no longer a stable time, not to mention Zhao Chengzi's master Wei Huacun, even the brothers who bullied and teased him on weekdays also went to the battlefield one after another, and fought with the flying demons outside the sky, life and death were unpredictable.

On the contrary, it was Zhao Chengzi, because he left the master and respected them, he was no longer a monk of the Ladder Immortal Kingdom, and he was spared the pain of going to the battlefield to fight with the flying demons outside the sky, and he didn't know whether it was fortunate or unfortunate.

However, after Zhao Chengzi knew about this, he was very anxious, and felt that Shizun must have known about it for a long time, so he pushed the boat back to his home, so he hurried back to Yingzhou, but after he left the sect, he had no news from the sect, and when he knew that after the invasion of the heavenly demons, the war had almost been fought. At the same time, Zhao Chengzi is weak, even if he keeps rushing to Yingzhou day and night, it will take a lot of time.

When Zhao Chengzi was in a hurry, he suddenly seemed to have an understanding, and felt that instead of running to Yingzhou to die, it was better to repair the secret given by the master, and then rush to Yingzhou, and then he would be able to help the master fight against the heavenly demons.
