Chang Manzhi was slandered for peeking into the forbidden books and secretly practicing the forbidden books. The Shangqing sect threw people into the Cleansing Pool as punishment without finding out. Because she had been seriously injured when she went out to deal with the monsters causing trouble in the world, and she could not bear the three punishments. She died at the bottom of the Cleansing Pool. At that time, her friend Mu Yinsong was too busy because of the destruction of the demon world barrier. She didn't know that something had happened until she saw the Tongxin lamp extinguished.
Mu Yinsong jumped into the Purifying Pool to fish out Chang Manzhi's body, intending to take revenge and take him back to the Demon Realm. However, because he was seriously injured in the Purifying Pond and could not use his spiritual power, his brother took him back to the Demon Realm and imprisoned him for three hundred years.
After being released, he has been thinking about revenge, while looking for the last thing needed to go to the underworld.
Intention: Kindness
