Sakuya transmigrated into the Naruto world and became a member of the Uchiha clan, a family wiped out by their own people! Luckily, he awakened a god-level daily login system, earning rewards simply by logging in every day! Day 1: Navy Six Powers! Day 2: Whitebeard character card! Day 3: Zanpakuto: Kyoka Suigetsu... And so, without realizing it, Sakuya became invincible! When the Third Hokage and Danzo planned to attack the Uchiha clan, Sakuya smiled and shattered the Hokage Rock with a single punch! Sakuya: "From today onwards, I stand in the heavens!" Minato Namikaze: "Sakuya's Flying Thunder God Technique is even better than mine, what am I called the Yellow Flash for?" Madara Uchiha: "In this ninja world, only Sakuya is worthy to dance with me!" Onoki: "His Susanoo is bigger than a mountain, no joke!" Kushina: "Sakuya! I want Gear Second Vibration Mode!"

Cheng Sui transmigrated to the Dragon Clan world. Just as he was about to graduate from Kassel College after four years, a system arrived. But what the heck was this "Naruto Counterattack System"? He was still classified as a perennial Chunin, an ordinary teacher at the Ninja Academy. [Uchiha Sasuke and Uzumaki Naruto are fighting again in class. The Third Hokage is currently watching this with a crystal ball. You need to use reasonable means to resolve this conflict.] [Mission Rewards: Favorability with the Third Hokage, One-Tomoe Sharingan, Uzumaki Clan Physique] Cheng Sui: "???" Looking at Chu Zihang and Caesar passionately slashing at each other, he fell into deep thought. Years later, when the Dragon King roared across the world, and the giant Susanoo rose from the ruins, Cheng Sui, in Sage Mode and wearing a Tailed Beast Cloak, looked down at the Dragon King beneath his feet. "System, is this what you wanted me to subdue..."

Upon waking, Ning Chuan discovered he had traveled to the world of Douluo Continent, becoming a minor figure with mediocre talent and no one to be reckoned with. However, unlike all other travelers, he had not acquired any god-level martial spirit or heaven-defying system. Instead, bound deep within his soul was a garbage collection station connecting all the heavens and universes! Every day, "garbage" from different planes and universes was dumped there: broken artifacts, scrapped mechas, fragments of unknown techniques, depleted magic cores, and even the corpses of alien monsters... To others, these were all useless waste. But in Ning Chuan's eyes, these were truly coveted treasures! "Reclaim the shattered fragments of the imperial weapons from the world of 'The Great Ruler,' extract a wisp of the Mother Qi of all creation, and rebuild the foundation!" "Reclaim the Aoki from the world of 'Marvel'..."

Thanks for the invitation. I am currently in the ninja world, just resurrected. I am now the divine son of the Evil God Cult, the chief spokesperson of the Evil God, and the number one lackey appointed by the Evil God.

Based on the principles of dedicating his life to fighting for the Evil God, the Evil God being supreme and omnipotent, the Divine Child Simu devised the [Sacrifice the Ninja World] plan.

Orochimaru: "Only by submitting to the evil god can I obtain eternal life."

Nagato: "True peace is achieved by sacrificing the entire ninja world. Without people, there will be no conflict."

Obito: "I want to create a world where only Jashin exists."

Deidara: "The Jashin-sama is the true art!"

Decades later, the evil god was resurrected and, looking at the Allied Shinobi Forces that came to punish him, slowly typed a question mark.

"I've been sealed away for hundreds of years, and now I'm the public enemy of the ninja world?"

Kyle's third time traveling through time brings him to a world far more bizarre and dangerous than those of One Piece and Naruto. The painful experiences of his first two journeys, where he died in swords and kunai upon inheriting his memories, taught him this: if you're not strong enough, you die! Awakening his Nen ability at the age of seven, he possesses the power to turn everything around—the Book of the Unique World Resonance! When Gon needs strength to challenge Hisoka, Kyle extends an invitation: "Sign a contract. I'll grant you the opportunity to train in another world, and you'll grant me the power to reflect back." Thus, the Hunter world's strongest pirate group sets sail, and an organization more powerful than the Akatsuki in the Ninja World is born. But Kyle harbors a deepest secret: does this seemingly fair contract reflect the fruits of training, or does it reflect the fate of the contracted... themselves? As the bonds of the powerful from three worlds intertwine, what awaits them is the path to the highest...

A time traveler who opens their eyes and enters the world of Naruto is quite bewildered. So I'm called Oda Nobunaga by such a domineering name! My opponents aren't monkeys, cranes, turtles, tigers, etc. Instead, I have to face the grudges and hatreds of a family of aliens that are causing unrest in the world! Even worse, there are powerful ministers at home, and Orochimaru standing sinisterly before them. I'm not even related to that family of aliens. Fine, fine. After a lifetime of hard work, I wield a long-term strategy to rule the world, swallow up the Otsutsuki, and destroy the ninja village. Here, I don't care about background, only talent! With all the wise men gathered, why worry about the unrest in the world?
