Demon Suppression Division: Starting as a Jailer in the Cycle of Reincarnation to Become a Martial G

Su Wu transmigrates to a fantasy world and becomes a jailer in the Demon Prison of the Demon Suppression Division.
Fortunately, he obtained the extraordinary treasure "Book of a Hundred Lifetimes," which allows him to be reborn after death, bringing everything back with him. He can also bring back the treasures, cultivation, and lifespan from his previous life, and awaken special talents.
Seeing that chaos was imminent, Su Wu originally planned to hide in the Demon Prison, but the Demon Prison was even more dangerous than he had imagined.
In his first life, Su Wu was betrayed by a fox demon who drained his vital energy.
In his second life, he was framed by a wicked boss and died tragically in prison.
Third incarnation, fourth incarnation...
It wasn't until a hundred generations later, when Su Wu looked back, that he realized he had unknowingly stood at the pinnacle of this world.
