Heaven's Codex

Mu Chenyu, a seemingly ordinary university student.   With a heart ensnared by the allure of novels, his days were spent wandering through fantastical realms, letting reality drift by.   
But life has a curious way of turning the mundane into the exceptional, and for Mu Chenyu, it arrived in the form of an apocalyptic horror.
When the world descended into chaos, with the undead reigning supreme, Mu Chenyu's life was turned upside down. But thanks to his vast reading experience, he remained unnervingly calm amidst the panic-stricken masses.   He had, after all, already faced such horrors, albeit in the safe confines of his imagination.
Yet, this tale is not just about survival against the walking dead. Central to Mu Chenyu's story is the enigmatic black book, a relic from his childhood. Discovered in a secluded valley and persistently reappearing in his life, this seemingly blank tome held secrets unknown. But as the undead threat loomed larger, the book's dormant power began to stir, revealing itself to be an invaluable ally in the fight against annihilation.
As Mu Chenyu battles hordes of zombies, the boundaries between fiction and reality blur.
