Global Distortion: My Skills Can Be Infinitely Upgraded

[I have started a new project, I am too busy, and the writing is also very messy, so updates are temporarily suspended] The world is distorted and monsters are rampant. People are struggling to survive and may be hunted by monsters at any time! In the last life, Du Xiao tried his best, but only reached the fifth level... With Aghanim's Scepter to resurrect his life, all the monsters were digitized, and Du Xiao decided to enter the Taoism as an assassin! From then on, a phantom assassin was born, whose skills can be infinitely learned and upgraded. He danced the light of his sword in the darkness, and from then on the monster's wailing sounds turned into music around him.
