He was once the tyrant Lingjun in charge of the five realms. He used divine fire to burn all disobedient people, and even the peach forest in the heavens turned into scorched earth under his feet. Until his cronies rebelled, extracted his divine bones, refined them into puppets, and massacred people in his name - the demon race stained the wasteland with blood, the human race's city collapsed, the gods fell like a shower of stars, and the order of the five realms collapsed like a broken mirror.
Ling Jun, who still had a lingering soul, saw his best friend turned into withered bones in the puppet's body, and a child crying and wailing, and finally cultivated kind thoughts in the darkest place. He burned his body on fire, entered reincarnation with his soul, and went through the nine levels of heaven: the first level cut off greed and anger, the nine kalpas excavated the inner demons; the second level burned sins, and the nine kalpas refined the yang soul... In the 99th and 81st tribulations, he broke through the sea of blood in the underworld, killed all the beasts of chaos, and quenched the body of perfection and yang from the sea of bones in the mountain of corpses.
When he returned from Nirvana, he held the spirit of chaos in his palm, and the laws of heaven and earth trembled. The former tyrant has become the only one who can seal the rift in the five realms - using his soul as a sacrifice, using the power of yin and yang to reshape the mountains and rivers, suppressing the dragon clan in the East China Sea, and sealing the demon king in the nine abyss. However, he is willing to fall into nothingness forever in exchange for a corner of peace for all living beings.
