The Chaos Disc Starts with Lin Daiyu

Zhang Yudie finds a transmigration artifact in a dream, engraved with the seal-script characters "Chaos Disc." After fiddling with it for a long time, he discovers that it has the remarkable ability to let him transmigrate. At present, it can take him to several worlds, including Dream of the Red Chamber, Water Margin, and Investiture of the Gods. It also provides the Primordial Creation Art, which is said to let its practitioner merge with the Heavenly Dao once mastered.

Since he's just an ordinary mortal with pitifully weak combat abilities, he'll first take a look around the world of Dream of the Red Chamber.

Once he grows stronger, he'll go explore Water Margin, Investiture of the Gods, and the other worlds.
