My Good-For-Nothing Young Master Is Actually a Full-Level Emperor Immortal

[Good-for-nothing Vest + Return at Full Level] The strongest immortal emperor in the three realms is actually being treated as a doormat by a fallen sect! The good-for-nothing young master that everyone despises is actually the supreme master who fell a thousand years ago. When the ancient memory awakens, the plants and trees that were randomly enlightened in the past are all magical medicines, and the exercises that are boring are all lost secrets. He low-key repaired the collapse of heaven, but his strength didn't allow it - the little junior sister he trained casually became the pride of the world, the local dog picked up on the roadside turned out to be an ancient divine beast, and even the reincarnation of his enemy Demon Lord came to cry and beg to be hugged. When the conspiracy to destroy the world came again, he lazily raised his eyes and said, "I am rebuilding my life just to finish what I didn't say back then - everyone here is rubbish."
