Naruto: I Can Add 999 Combat Power with One Punch

I thought I could only serve as cannon fodder in the Second Ninja War. Unexpectedly, after turning on the system "Ding!!! Congratulations to the host for adding 999 combat power." ………… How simple! Just one punch can increase combat power. I'm not strong enough, so I'll throw a few punches first. This novel and its characters are purely fictitious.
