Naruto's Ultimate Blood Follower

As a game designer, Rong Lin was entrusted with a lot of money to design a monster-like character.
But I don't want to travel into the Naruto world with some sky-defying abilities after the game characters are set.
Unlimited upgrades of Baiyan, Sharinyan, and the mysterious and sky-defying special time blood follower limit.
The feeling of watching other people grow old without the signs of the years on your face seems to be not bad!
At least Uchiha Ronglin thinks so.
