When You Wake Up, All the Characters in the Book Have Turned into Monsters?

Ye Liuhuo just took a nap during class. When he opened his eyes again, the world was completely different from what he knew. The male teacher in class, whose surname is Zhuge, was holding a feather fan and looking sickly. The principal is an old man with a white beard who calls himself Liu Bei. He likes to play the pipa in Taoyuan. The second master is majestic with the Qinglong Yanyue Sword, but how did he become the dean? And how did Zhang Fei, a rugged man with a leopard head and ringed eyes in the book, turn into a sexy and hot beauty who likes to wear tight red armor? In this world, the characters engraved in history books really exist. Not only characters that exist in historical records, but also characters in fairy tales and gods that only exist in human imagination, all really exist in this world. Even a special period like the "Renaissance" became a pirate captain riding the waves of the Atlantic Ocean. And they all have a unified title. The name is: Weird Spirit.
