I Don't Want to Work Hard, but My Strength Doesn't Allow It

Yan Wuxi, a young man from a small town, has had his biggest worry in the past sixteen years being that his parents urge him to practice swordplay. His parents were casual cultivators in the Zangfeng realm. They had been stuck at the threshold all their lives and had placed all their hopes on him. However, Yan Wuxi just wanted to dawdle - practicing swordsmanship is so tiring, it is better to lie down. Until one day, he mistakenly entered the forbidden area behind Xuanque Terrace. There is a person sealed there, a name who killed the demons three hundred years ago. That person's name is Yan Xintan. He was in the unique realm of swordsmanship and could kill thousands of enemies by himself, but suddenly disappeared at the peak of his powers, and no one knew where he was going. Deep in the forbidden area, the seal was loosened, and a weak soul looked at the young man who broke in with a complicated expression. Because Yan Wuxi was the soul that he carved out with his own hands. Three hundred years ago, he watched everyone around him die under the sword of the demons, and he became a sword that only knew how to kill. Before he was sealed, he took out a ray of his soul and threw it into the human world. He only hoped that this small part of himself could live another kind of life - he didn't have to become a peerless master, as long as he was safe, happy, and had someone to accompany him to grow up. Now, that soul is back. Outside the seal, some people are trying to uncover the truth of the Three Thousand Worlds. Some people are eyeing the vacant world master position in the Qian world, and some people are whispering a name in secret: "First." Yan Wuxi yawned and asked, "So I have to start practicing sword practice now?" Yan Xintan was silent for a moment: "... It's okay if you don't want to practice." "Really?" "Anyway, when the enemy comes over, you will be the one who gets beaten." ——This is a story about a protagonist who doesn't want to work hard, and a past life who doesn't know what to do with him, and is drawn into the whirlpool of three thousand worlds.
