My Reincarnation Is Not As I Expected

The Undying-Reincarnation Technique. In legends, it is described as 'heaven-defying'. By sacrificing a large amount of Spiritual Energy, one can cheat death at the expense of losing their chance to ever reincarnate after being killed in the future. When faced with a life-long enemy of his, the genius Tian Feng decided to use this technique in hopes to get revenge against his enemies. However, after using it, he awoke in modern-day earth with memories scrambled, and also, no physical body of his own. The only way for him to gain a body is to train a disciple to greater heights than he previously was at. But, the problem is... 'My disciple is a genius... But why the hell is he such a terrible person?!' So, now begins the light-hearted reverse-transmigration story between the prideful master and the cynical disciple.
