Western Fantasy: the Strongest Magic Teacher and the Rookie System

Lin Shi felt that what he got should be Long Aotian's script. After traveling through time, he became the strongest magician in the continent from scratch. But unexpectedly, while studying ancient magic, he overturned and was turned into ashes by the turbulent flow of space. When he opened his eyes, he found that he was reborn again, 300 years after his previous life. I thought this wave could not be more stable. Shen Ming skillfully chanted the incantation of god-level god-destroying magic, preparing to return to the top immediately. Bite! It is detected that the host has excellent talent and is bound to a super strengthening system! [It is detected that the host successfully understands primary magic, power +5%] The flaming phoenix spread its wings and instantly shrank into a small flame. Lin Shi:...? He did not believe in evil and began to draw the ultimate magic formation that would trap and kill the superior monsters. [It is detected that the host draws a magic circle for the first time, and it is automatically upgraded to a "lower magic beast trapping array", with an effect increase of 5%] The next second, the lower-level monsters within a ten-mile radius came smelling the scent. Lin Shi ran away. Behind him were a group of drooling low-level monsters. "Lin Shi? That loser who only knows how to make small fireballs?" Most people laughed at him. But Lin Shi was miserable and couldn't tell. His system seems to have misunderstood him. Every time, the ultimate skill is forcibly reduced to a novice skill, and a 5% temporary buff is thoughtfully added. The problem is... Just 5%? 5% Forever? ? In my last life, I was a "walking natural disaster"! ! ! ……… In this way, Lin Shi successfully graduated with this oil bottle system and worked at the Third Magic Academy. Lin Shi: I hope I can spend my working time safely. System: I don't think so.
