Just Returned from the Ninja World, Only to Find the Spiritual Qi Revival?

[The Strong Return] [Power Fantasy] [Invincible Male Lead] [Ninjutsu] [Sharingan] [Susanoo]

Li Xiao, the legendary ninja, the strongest in the ninja world, and leader of the Uchiha clan.

He made his name in the Third Ninja War, and nearly destroyed the world in the Fourth World War, driving the Five Kage to despair. He was known as the "Purgatory Asura."

Until Uchiha Obito ambushed him. When he woke up again, he found himself back in the modern world, with his Sharingan and almost all the ninjutsu of the entire ninja world.

And so, a new era dawned upon the modern world.

A Susanoo hundreds of meters tall could split an entire mountain range with one sword strike;

A Fire Release technique spanning hundreds of kilometers could evaporate a lake in a single breath.

Tengai Shinsei, the Eight Gates, Shinra Tensei...

Come on, you beasts. Face your god!

But wait, why has spiritual qi revival begun in the modern world too?
