In a World of Chaos with Demons and Monsters, I Use Killing to Save People

The fairy world collapsed, hell manifested in the human world, and wanted to destroy the human race. The Heavenly Emperor Shitian sacrificed himself and turned into a monument to protect the human world. The Human Emperor Yingzheng led a hundred thousand heavenly soldiers to conquer the heavens and established a demon-suppressing department to kill human beings, monsters, hungry ghosts, and cults. 500 Years later, the fate of the Qin Dynasty declined. The latest generation of human emperors succeeded to the throne, and they were extremely stupid. Among them were monsters who caused trouble for the imperial court. At the same time, cults invaded the court. Chu Yi rose from the sky, entered the Demon Suppressing Division, awakened the demon-slaying system, and became stronger when killing demons. Chu Yi turned the tide and saved the common people. Become the strongest demon-suppressor in the Qin Dynasty, then conquer the heavens, kill the final evil demon, and prove immortality.
