Versatile Mage - Master Assassin

He Chen was originally just an ordinary 18-year-old young man. There was nothing special about him except that his parents' death was a bit more tragic than others. But since a few days ago, his brain has always been groggy, as if something wants to break away from him. The most important thing is that he had visions. He could see strange black lines appearing and disappearing in the sky, as if they were cracks in a piece of glass before it was about to break. I really think too much, how can the sky look like glass? He Chen gave up his strange fantasies and asked for a day off from the convenience store, intending to take a good rest. As a result, when he woke up, he saw a huge crack across the sky, and countless flames and black smoke fell towards the city. Damn it, are you serious? What happened to Cao Dan was more than that. He Chen found even more desperately that he might have traveled through time. After all, the strange black shadow outside the window, which is comparable to a tall building, does not look like a local! ! (This is the story of a person who has never seen a full-time mage who travels to the world of a full-time mage, fights monsters and upgrades, pretends to be cool, saves the world, and finally becomes the King of Darkness.)
