Demons for All: Start with Thresh and Imprison the Demon God

My name is Link. At the beginning, I traveled to Runeterra and merged into Thresh. As long as I complete the tasks in the three worlds, I will be able to return to my home planet with strength. This is my last world, the demon world! ........... My name is Jiang Xiaoxiao, one of the strongest demon masters in Daxia! The oldest demon god has resurrected, and even if I die in battle, I can't stop him from destroying the world. Fortunately, a small lantern I picked up took me back ten years ago, giving me a chance to change history! But when I wanted to contract the Demon King, the owner of the little lantern appeared. He is so powerful that he can destroy the devil with just a raise of his hand! Under his oppression, I was forced to sign a contract with him. I originally thought he was strong enough. But what I saw was just the tip of the iceberg... He is the devil among devils! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
