Wang Yisu gets conned into taking over a battered old book by his classmates. To his surprise, it can communicate with powerful figures who have died, and he can borrow and wreck the magic treasures they cherished most in life.
Facing a supreme powerhouse, he raises a finger. “How many is this?”
“Two?”
Hellfire blazes: “Two minutes. That's all it'll take to kill you.”
Facing a bewitching demon from the Yao clan, he draws his sword. “I'm afraid not. A gentleman must be cautious when alone.”
“Is something wrong with you down there, young master?”
A flash of cold light: “You're pretty bold.”
Facing an awakened eldritch entity, he strikes with a heavy punch. “You say you just want to live in peace?”
“Yes, yes! How were we supposed to know they were all your younger sisters? We'll never bother them again.”
A train roars past: “Tell my sisters that in your next life!”
In the midst of a great battle, the third-in-command of Chaos looks at the boy, still steaming, and wears an expression of despair. “I'm so tired. What kind of person has an infinite supply of magic treasures?!”
“That's it? Easy.”
The second-in-command of Chaos demands, “Why are you covering your face?”
“Gods have no fixed form.”
At last, the first-in-command of Chaos speaks. “Who are you, exactly?”
“Haha! Standing before you is the only guest elder of Kunpeng Island, the only person in history with a three-character divine ability, the strongest divine-level Dao-merge cultivator of this age, and the master of the most powerful magic treasures under heaven, honored by all as the Immortal Lord of the Train.”
