Dragon Clan, I Dominate in Kassel

My name is Tantai Cheng, a time traveler, and I am currently the temporary president of the Student Union of Cassel College. I am not too dissatisfied with this time travel. Although my bloodline is not strong and my golden finger is only average, my golden finger behavior does not need to be elevated to an individual level. I am strong in every sense. I don't like tragedy very much. Whether it's a long story specifically designed to depict a sad scene, or a painful literature about falling in love but killing each other after a long period of twists and turns, or polishing a flawless jade and then smashing it into pieces at the last moment, or a dismal ending of giving everything but getting nothing after repeated cycles... For me, this is just repeating the same mistakes without growth. Before I appeared, the will of the world was watching the bad boy. But now that I'm here, they thoughtfully gave me an open-book exam. Then, all celestial bodies will revolve according to my will! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
