After transmigration, Lin Yue could hear a voice whispering in his ear every day, sharing all sorts of secrets with him.Small matters like the thoughts of the girl next door, to great mysteries like the secrets of the heavens, the voice persisted daily, broadcasting randomly.He originally wanted to live an unremarkable life, but in this world of Xianxia dynasties where mortals are considered as insignificant as weeds, the fate of an ordinary man without power is no longer in his own hands.Thus, he had no choice but to stop being 'just a person'.'Your Majesty the Empress, you wouldn't want your secret of treason to be revealed by others, right?'

“No one is standing in the sky to begin with.”

“Whether it’s Hokage or the God of Ninja World.”

“But the window period for the Throne of Heaven has been too long.”

“From today, I will stand in the sky.”

Above Konoha, Naruto Uzumaki’s hairspray hand touched the drooping bangs, revealing sharp eyes.

Boiling blue light descended from the night, pulling Uzumaki Naruto away from the sky.

In Muye Village below, countless ninjas looked shocked and unbelievable.

Iruka: “Impossible, you are not that gentle Naruto, who are you?”

Kakashi: “The disciple I know is a gentle boy who will always take care of and protect others and inherit the will of fire.”

Uchiha Sasuke: “Naruto, you pulled me out of the abyss, but why do you want to leave now? Damn, even if you break your limbs, I, Uchiha Sasuke, will bring you back!”

PS:

A Naruto who was not influenced by Ashura Chakra, accepted Aizen’s teachings, was gentle and refined since he was a child, but was actually ambitious and deep-minded.
