Immortal Lord Qing Mo personally "killed" his demonic senior brother Mo Yuan a hundred years ago and guarded the empty tomb alone for hundreds of years. Unexpectedly, Mo Yuan came back from the dead, transformed into a young man "Li Yuan" and became a disciple, full of hatred just for revenge. During the entanglement, the centuries-old truth was revealed - that sword was actually the cruelest protection in desperate situations.
Hatred collapsed and love rekindled. The two were forced to join hands to break into the secret realm of chaos and form a symbiotic contract between life and death. When the mysterious organization "Xu", which intends to annihilate the Three Realms and return to the beginning of time, surfaced, the two immortals and demons stood side by side. He burns the sea of stars with the power of chaos, and he determines the universe with the brilliance of the world core.
This time, they are not for immortals and demons, but for each other and the common people.
