Qin Chen thought he could spend the rest of his life signing in at different places until he became invincible.
However, when the ruins of the Great Kingdom appeared in the Holy Land, people from other holy places, famous families, and even ancient empires gathered to defeat the all-powerful Demon King, who appeared with the ruins. The demon king had killed countless humans and was planning to destroy the ancient holy land.
Qin had no choice but to stand up. After finishing off the demon king with a single slap, he sighed, “Why do you people force your unreasonable demands on a single servant?”
