Naruto the Ninjutsu Maniac

Rongxing suddenly became a ten-year-old boy and obtained the chakra system. As soon as he woke up, he found that there was a kunai next to him, as well as a ninja wearing a forehead protector. I thought that with chakra in my body, I would be invincible, but I was mercilessly mocked by a little guy. Rongxing is depressed... "What's going on? I'm obviously playing games and drinking drinks at home?" "No matter! I want to become a ninja in the village!" "I want to learn all the ninjutsu here!!" "I want to be a unique ninjutsu madman!!!"
