Naruto: Earthonline

Many planes such as the ninja world have created channels with the earth one after another. Characters in anime and strong men from other worlds have traveled to reality, and they fight for their respective planes. Looting resources and killing humans. None of this happened! Because this version of humanity is terrifyingly strong. You want to ask why? This has to start with Lingke using chakra to condense pills to start cultivating immortality... This book is also known as "Cultivating Immortality as soon as I Learn Chakra" and "Reverse Invasion into Another World with a Cultivation Speed of More than 7,000 Times". Kisame: Kid over there, I suggest you go farther away. The tailed beasts in our ninja world are very dangerous! (Making seals carefully) Lingke: Uncle Kisame, I suggest you stop forming seals. By the time you finish the spell, this big cat will have run away. (Facing the out-of-control Kyuubi, taking off on the spot) Bold monster, I want you to show your true colors, the mighty Tianlong! Kyuubi: Meow?
