Rebirth: from the Underworld

An undercover agent was killed by a drug lord because his identity was exposed. At the moment before his death, he was temporarily placed in the underworld by a cultivator. Monsters were rampant in the past, and Yin soldiers were chasing after him. There was no one to guide him on the path of cultivation, but firearms and ammunition became artifacts in the underworld. Whether the masters in the Yang world can successfully counterattack in the underworld and enter the gate of the underworld, we will wait and see. This novel and its characters are purely fictitious.
