Naruto: From the Start, I Stole the Nine-Tails Chakra

Ye Yu suddenly discovered that he had become a baby after transmigrating into the Hokage world. He was also in the middle of the Nine-Tails’ attack. He was about to be crushed to death beneath the Nine-Tails’ foot! But when the Nine-Tails brought its foot down, Ye Yu not only survived, he also gained a complete Nine-Tails of his own. The most incredible part was that his Nine-Tails could grow without limit, from a Nine-Tails into a Ten-Tails, and then into a Divine Tree. Each time it grew, Ye Yu received one-tenth of its chakra and life force. His ever-growing Nine-Tails supplied him with a steady stream of chakra and life force. Ye Yu decided to lie flat, while the Nine-Tails became his overworked laborer, cursing as it trained to increase its strength every day. But the stronger it became, the more chakra and life force Ye Yu received. In the end, Ye Yu even awakened Wood Release, gained a Sage Body, and unlocked the Sharingan, the Rinnegan, and the Nine-Tomoe Rinne Sharingan. When the Nine-Tails became a Divine Tree, it still couldn’t break through Ye Yu’s body. It completely lost it!
