Chu Xiu, the eldest son of Emperor Zhou, was feared by his father and was accused of collaborating with the enemy and demoted to a commoner. The moment he left the palace, the god-level sign-in system was activated. Sign-in from the palace went directly to the gods on land. He traveled around the world under the alias Gongzi Xiu, signed in to harvest divine swords, exercises, and pure Yang true fire, conquered Bai Yue, Ye Ling, and others, exposed Prince Li and Chu Yun's collusion with the underworld, quelled the Japanese-worshiping army, frozen demon disaster, and entered the demon world. Kill multiple demon kings, solve the old case of the Yang family's extermination, support his sister Chu Nichang to ascend the throne, and finally permanently seal the demon world with the spiritual root of chaos. He puts down his power and travels the mountains and rivers. There is a new chess game hidden deep in the demon world, and the foreshadowing continues.
