A young man of the new era was bullied at school when he was a child and was forced to attend a cram school. He had no grades because he did not study seriously. He had a crush on a female classmate but did not dare to tell him. When he grew up, he was killed for his friends. After half of his life, where his parents only looked at the results but not the process, he traveled to people with different names and began to cultivate his body in a different way. Here he is a unique genius, unrivaled by his peers, and beats people at a higher level. Finally, he returns to the week of his previous life to save the world, invincible text.
[Somewhat cool, but not entirely cool, not brainless, genius, hard-working student of the new era, time travel]
