NecoArkForever
The MC can use the 8 gates for a power up, also the hero water from Rainfall Village i think its called.
Sage mode then, a human sage like hashirama? or practising senjutsu in the fire temple of Land of fire?
NecoArkForever:not really hero water is only temporary and shortens life #/#/#/#/The Eight Gates exist in order to limit the flow of chakra within an individual's body. Normally, individuals can use no more than 20% of their body's full potential, the brain's way of protecting the individual from harming their body through overexertion. With training, individuals can learn to remove these limiters, referred to as "opening" the gates.[2] With each opened gate, individuals are given access to more and more of their body's chakra, thus increasing their physical strength and speed.#/#//#/ MC has no chakra at all to open it
