In Shiwa Village on the border of the Eastern Region, young Ye Fan was born with mortal bones and his meridians were blocked. He was ridiculed by the whole village as a useless person in cultivation. He was once obsessed with the ancient legend of "immortal slaying demons", but on the night of the blood wolf pack's raid, he witnessed his parents dying in battle to protect him, leaving only a seemingly ordinary "mortal iron ore" behind.
After his family was destroyed, Ye Fan lived in the Black Wind Gobi, struggling to survive in the desperate situation of scorching sun, sandstorms and monsters. When he was about to die, the ore in his arms shattered, revealing the chaotic marrow crystals, which washed the marrow and cut the veins, transforming the mortal bones into a chaotic body, allowing him to embark on the path of physical and mental cultivation.
From the difficult survival in the desert of the mortal world, to the emergence of the sect in the spiritual world; from the pursuit and suppression of the fairy court in the fairy world, to the ultimate showdown between the gods and kings in the divine world. Ye Fan carries the secret of the Chaos Marrow Crystal, gathers the original power of the four realms, uses his mortal body to fight against the injustice of the realms, and breaks the shackles of class.
He met loyal comrades, encountered cunning and cunning enemies, and uncovered the truth about the ancient war between gods and demons and the secret of the depletion of spiritual veins in the four worlds. Counterattacking all the way, from the body tempering realm to the god king realm, from a lonely boy to the guardian of all realms, Ye Fan used his blood and tenacity to prove that mortal bones can defy heaven, and chaos will eventually be unified. And when the four realms return to balance, on the other side of the origin of chaos, the more mysterious shadow of the void realm is quietly approaching...
