Blood Ribs

Transmigrate, xuanhuan, supernatural mysteries, and puzzle-solving, with tightly connected twists that get more exciting the further you read. A long novel worth reading twice.

An ordinary high school student accidentally discovers his true identity, and his archenemy becomes his "tutor." His grades and his life both turn around. Using the power of mathematics, he creates new rules, battles the Yin Emperor, breaks through the Realm, and resets the world's rules. Is he someone who transmigrated into a book? A vessel? A mortal? The Ghost King? A classic xuanhuan novel with a wildly imaginative premise.
