I Became the White Impermanence 我竟成了白无常

The former No. 1 God of War in the underworld was reincarnated into a mediocre high school student.
But the gears of fate are turning.
When the law of heaven collapses and evil comes to the world, he must put on his battle armor again.
Under the guidance of the cold goddess Hei Wuchang, he will fight against the ghost emperors of the five directions and the Yamas of the ten palaces.
The king returns, breaks through the three realms, dominates the world, reorganizes reincarnation, and is the only one who is supreme!
