Demons are rampant and human life is like grass. Shen Changqing is just an ordinary jailer in the sky prison. His only source of support is the mysterious panel in his brain that can consume life span to improve his martial arts.
It wasn't until he killed the first demon that he discovered the real secret - he could absorb [Demon Life Essence] and become stronger without any loss!
The government government made peace with the demons, sacrificing the people in exchange for a false peace? The boss's order was to compromise, but his choice was to kill them all! While they were still running to compensate the demon king for his cattle and sheep, Shen Changqing had already picked up the knife and embarked on the taboo road of harvesting demons and becoming infinitely stronger!
"Your rules cannot bring peace."
"My knife is fine."
