On the Eve of the End, I Open My Eyes in the Abyss

This is a world where the outside and the inside are intertwined. Under the neon lights of modern cities, there are anomalies that follow "laws" and "paths" lurking: scarlet eyes, deathrattle curses, abyss worms, strange shadows in the fog... The guardian "World Peacekeeping Headquarters" stands there, using the monument as a guide, to fight against the erosion from other dimensions. Chu Chuan, codenamed "Time Zero", is the youngest third seat in the headquarters. Underneath the inhuman perfect genes is the absolute power to control time and space. He walks on the edge of light and darkness, disguised as a student, and kills the horrors that endanger reality. However, abnormal events suddenly escalated, with the rebellion of the stone giants, the restlessness of the Blood River Abyss, and the whispers of the dead becoming increasingly clear... The prophesied "Knights of the Dead" are about to arrive, and all clues are faintly pointing to the legendary law that will eventually destroy everything - "The End." Armed with the power of time and space, and holding the Zanpaku Black Sword in his hand, can Chu Chuan understand the mystery of himself and reverse the desperate future before the end? In the end, he will face the final battle that can overturn all worlds!
