MTL - My Backyard is the Tang Dynasty - ~ explain!

Until the time of him becoming the master of the lowest rank in the order of rankings, the lonely side of his life without luck was changed.

Frank, a mercenary known for his cold ruthlessness, decides it’s time to leave the bloody world of the underworld behind. But the underworld has no plans of letting him go. Relentless enemies from his violent past keep hunting him, and eventually, they succeed—Frank is killed.But fate has other plans. Instead of staying dead, he is mysteriously reincarnated into the body of a cop in a world filled with crime, corruption, and dark secrets. With the help of a strange, all-knowing system, Frank is given the chance to live again—this time, to prevent crime before it happens.

“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.
