Dimensional Invasion: Invincible in Another World with Ninjutsu

[Transmigration + Otherworld + Dimensional Invasion + Naruto + One Piece + Bleach + Spiritual Qi Revival]

In his previous life, Xin Yi was an otaku obsessed with anime and manga. Carrying his memories with him, he transmigrated to a world overrun by monsters, where everyone could cultivate ninjutsu.

Some people could even awaken Devil Fruits and Zanpakuto.

With memories of his previous life and knowledge of every ability, Xin Yi would shock everyone in this world under dimensional invasion!

At the awakening ceremony, the school beauty awakened Hyorinmaru, the strongest ice-type Zanpakuto, while Xin Yi awakened the Five Nature Transformations.

During an outdoor training exercise, he activated the Sharingan when facing powerful monsters. When he encountered an evil organization, he activated the Kamui Mangekyo to protect the people important to him...

Xin Yi: "Fire Style: Majestic Destroyer of Flame, Lightning Style: Chidori, Kamui Mangekyo, Susanoo, Wood Style, Rinnegan, Planetary Devastation, Tengai Shinsei..."

Students at his school: "Is he really the same age as us?"

A ninth-rank powerhouse: "With Xin Yi around, what are monsters even worth?"

His enemies: "This guy is too strong! We can't beat him at all!"

P.S. This book has a System, but it isn't mindless wish fulfillment. There is a female lead, and she's strong. The male lead is a bit socially anxious at first, but gradually changes later on. (Hope you all enjoy reading! *)
