Mo Jin is a handyman disciple at the lowest level of Xuantian Sect. He is of inferior character and has been bullied all the time. During a life-and-death crisis, he accidentally picked up a palm-sized, rusty black iron box from the sect's forbidden area. No one knows that this is the remains of the "Secret Book in the Box" that makes the heavens tremble.
When Mo Jin's blood seeped into the iron box, the first page of the eternally silent secret book opened to him. There is no text in it, only a "visualization picture" and a fragmentary "Qi Qi induction method". By practicing this method, he was able to purify and devour all the mixed "turbid energy" in the world at an unimaginable speed, transforming it into the purest original power. Since then, his cultivation has advanced rapidly, and he even discovered the remains of a long-lost forbidden sword technique in the box.
However, as his cultivation progressed, the rust of the black box gradually faded, and it began to actively attract and devour the "abnormal" things around him - the murderous aura left over from the ancient battlefield, the alien essence in the enemy's body, and even the fragments of laws wandering between heaven and earth. The secret code is "growing" and is also quietly changing Mo Jin's physique and destiny.
Underneath the peaceful life of the sect, there are turbulent undercurrents. The jealousy of the inner disciples, the prying eyes of mysterious organizations, and even the whispers of sleeping ancient existences all converge because of this black box. Mo Jin gradually realized that what he held in his hand was not only the key to power, but also a source of disaster that could devour himself, his sect, and even the entire Jiuhuan Realm. He must use his "waste" body to uncover the truth of the secret book in the middle of this game between the heavens, and control this taboo power that can subvert the era.
