He Was in Konoha and Broke the Kazekage's Leg at the Beginning.

I traveled through time and became Hokage Rock Lee. Well, he is the tragic character who is at his peak when he appears and struggles but fails. The chuunin exams are coming soon, and I have to do it with Gaara. But I don't want to break my leg. And I also want to break Gaara's legs. What to do... ### Congratulations to the host, you have obtained the strongest struggle system. After doing 200 push-ups with one hand, you will get an immunity potion, which will make you immune to side effects within three minutes. After obtaining the system, I proved that hard work is not absolutely useless! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
