Everyone Transmigrates, and Each Gets a Grandpa in Their Pocket

Li Mu is at home eating hotpot and singing with a few friends when, without warning, he transmigrates. He wakes up in the body of the only son of one of Great Xia's top families. But this rich young master used to be a total simp, showering his goddess with money, gifts, and resources, only for her to never give him the time of day. Lin Baiwei: “Li Mu, besides coming from a good family, what do you have going for you? You're useless. Stop pestering me!” Li Mu: “Sure. Bye!” Lin Baiwei: “Wait! Leave behind the blood essence potion from that lion-tiger beast you were going to give me.” Li Mu: “??” Li Mu transmigrates without a System, but he does have an old man who lives inside him. The old man says his name is Taibai Jinxing, and offers to teach Li Mu the Nine-Turn Primordial Art, as well as produce all kinds of treasures. What's this? A peach from the Peaches of Immortality? And this? A golden pill? What's this one? The Green Duckweed Sword? Is it the Green Duckweed Sword I'm thinking of? This is a high-martial world! Only after the Eighteen Dragon-Subduing Palms, Li Feidao's Flying Daggers, the Three-Part Return to Origin Qi, and all kinds of cultivation arts appear in this high-martial world does Li Mu realize just how many transmigrators there are! And what a coincidence: he even runs into his first love, along with Deng Chao and Liu Yifei. Lei Jun, is that you? As the vast Primordial world is destroyed, the Saints use their immense power to send millions of its people to transmigrate to other worlds and make lives for themselves. This is the Primordial world's only way out...
