Transmigration? No, a plunge into hell.
Shen Ye, a relic restorer, triggers a blood-rusted bronze mirror while keeping watch at an ancient temple and is dragged into the "Hungry Ghost Hell," a place governed by bizarre rules.
Three hundred hungry ghosts suffer eternal hunger. A blood-red light that devours souls sweeps through every thirty breaths, and every supposedly safe direction is a lie.
At the brink of death, he somehow tears another "self" out of his own shadow.
[Clone awakened: One man becomes an army]
The clone fears no death, respawns every 24 hours, has its emotions stripped away, and is absolutely rational.
That's when Shen Ye discovers
"While I sleep, my clone practices breathing techniques for me, three times as efficiently as I can."
"When I'm afraid, my clone tests the ghosts' rules for me, risking its life to gather information."
"When I fight, my clone switches between the roles of Buddhist healer, Daoist talisman master, and Confucian scribe. One person is an all-purpose squad."
The whole world thinks he's a lone powerhouse, unaware that he carries an army of "selves" who are absolutely loyal and will never betray him.
