The Outcast: Bound to the Underworld from the Start, I Reap Souls with a Ninja's Head!

Jiang You transmigrates to an Otherworlder realm in the nineteen hundreds and binds himself to the Underworld Restoration System. He can grow stronger by guiding departed souls, subduing evil spirits to serve him, and building the Underworld. Jiang You is overjoyed. The nineteen hundreds! War is raging everywhere, and if there's one thing in abundance, it's the dead! While others wage war, he recruits! His ranks just keep growing! Head Ninja of Bihushan: “He's clearly stronger than I am, yet he keeps sparing me and slaughtering my subordinates! Is he a demon?” Tang Jiaren: “The Tang Clan never needed to take this job. Jiang You alone could wipe the floor with every ninja from Bihushan!” Zhang Jingqing: “It's a blessing for the Otherworlder world to have Jiang You around!”
