At the Demon-Slaying Bureau, I Became Invincible After a Century of Slaying Demons

Li Dao transmigrated to an ancient world overrun with demons and haunted by ghosts.

By chance, he joined the Demon-Slaying Bureau as a demon-slaying officer.

After accidentally acquiring a cultivation technique that could dispel baleful energy, he managed to scrape by in the Bureau for a hundred years.

Just as his body gave out and he was about to die, the System finally activated.

"Slay an Ancient Demon Dragon. Reward: 100,000 years of cultivation and the dragon's vital blood."

"Slay the head of an Immortal Sect. Reward: 1,000,000 years of cultivation and an immortal ruin."

"Slay a demon god of the demon race. Reward: 1,000,000 years of cultivation and a demon god egg."

"Slay a corrupt emperor. Reward: one empress?"

Li Dao: ...

From that day on, one ordinary demon-slaying officer vanished from the human world, replaced by an executioner wielding a demon-slaying blade, who cut down anyone in his path.
