Fantasy: I'm Already an Emperor, But the System Actually Asked Me to Accept a Disciple

[Invincible] + [Old Six] + [Gou Daoliu] + [Funny] + [Relaxed] Invincible from the start, Gu Changge travels through a fantasy world, is bound to a sign-in system, and signs in every day to receive cultivation rewards and various peerless treasures. While others were still struggling to break through, he had already stood at the top of the avenue and became a hidden emperor whose strength was unknown to himself. I wanted to just lie down and enjoy my retirement at Zizhu Peak, but the system suddenly issued a task - to recruit a disciple. Gu Changge had no choice but to pick up a few apprentices: The eldest disciple was born with the body of a god of war. He was given a copy of "Strategies of the God of War" by him, and as a result, he fought all over the nine heavens and ten earths and became an unparalleled god of war who swept across the universe. The second disciple, with the Chaos Sword Body, can break all laws with one sword. His sword is unrivaled in ancient and modern times. He points his sword to the sky: "My master said, the sword is as long as the person lives, but when the sword dies... my master will give me another one." The third disciple, the reborn empress, ascended the throne again, her beauty and grace overwhelmed all living beings. And his own sect, Qingxuan Sect, unknowingly became the number one sect on the continent. Looking at this group of extremely talented disciples, Gu Changsheng pinched the "Hongmeng Purple Qi" he had just signed in and fell into deep thought: — What happened to the promised retirement care? How did you become the strongest master?!
