Transmigrating into the world of Naruto, he becomes Tsunade's subordinate, but the system's mission demands he become the strongest medical ninja in the ninja world. Thus, Hoshigen Chisaku declares: "I am the man who will become the strongest medical ninja!" Years later, Hoshigen Chisaku questions: "What? Becoming Tsunade's man doesn't count as completing the mission?"... Disclaimer: Single female lead Tsunade, pregnancy expected~~

Having traveled to the Naruto world, Bai Mo joins the Akatsuki organization under the guise of being from the future, becoming the organization's sole strategist.

He started with a brilliant, unconventional strategy: sending White Zetsu to infiltrate the toilets of the five great ninja villages to collect toilet paper, thus elevating Hidan to the status of a true Shinigami and shocking the Akatsuki organization.

Xiao Nan: Is there any that aren't so sleazy?

Bai Mo: I heard that your divine origami skills can disguise yourself very well?

Xiao Nan: Mm.

Bai Mo: Disguise explosive tags as toilet paper, sell them in five major countries, and let the world feel the pain when they wipe their butts. Art is an explosion!

Payne, Deidara: ?

Bai Mo: Nisuke, if you really want power, just drink a sip of Naruto's 'milk'.

After awakening his past life memories, Ryan suddenly realized that he had traveled to Fairy Tail. Along with it, his own magic [Dragon Root] awakened, which could summon things with dragon attributes in other worlds.

With Blue-Eyes White Dragon under his feet, War Greymon, and Storm Dragon always by his side, and the dragon circling behind him, Ryan thought so, but...

Magazine reporter: Mr. Ryan, what do you think of your nickname of the Cute Dragon Summoner?

Ryan: I repeat it again! It's the Fierce Dragon! Not Cute Dragon!

Ryan really couldn't understand why he summoned cute dragons. And this reputation seemed to have spread to other worlds.

You must first hone your skills until they are as refined as Scáthach's; you must train your physique until it is as powerful as Typhon's; then, you must lift the sword left by the King of Britain, mount Pegasus given to you by Medusa, and set off for distant lands; along the way, you will breathe fire and unleash thunder; people will weave your name into songs and sing them, their voices trembling in the night. You will become a legend, a walking—Heroic Spirit. …“Becoming a Heroic Spirit only requires three steps: close the book, open the door, and then go out.” With these words, Shane, carrying the Book of Heroic Spirits that could summon countless legends and myths, arrived in the world of Fairy Tail. “Hmm, out in the world, let's slay a dragon first!” (PS: Even those unfamiliar with Fairy Tail and Type-Moon can easily read this; enjoy! QAQ)

"Look, look what I found! It's a starving Megumin. We can hire her for a small amount of food and use her as a disposable nuclear warhead." "Oh my goodness, there's a Naruto up there. He can use the Multiple Shadow Clone Technique, and his killing efficiency is a thousand times better than a Tumugou." "Oh my god, there's even a Mobius! Why don't we invest a little in exchange for her future patents?" "Great Lord! There's also a Tarua of the Reunion Movement here. This is Victoria's Crown Prince. It's time to emulate Lü Buwei." Russell, who joined the chat group, received a reminder—a cheat code that indicates where opportunities lie. However, is the opportunity indicated by his reminder wrong? After a moment's thought, Russell donned his monocle. Now, let's look at the residual value.

I created a chat group on a whim, but after traveling through time, I didn't expect that the chat group would become a cheat code.

Uchiha Izumi in the Naruto world, Kato Megumi in the heroine, Unohana Retsu in the Bleach world, Esdeath in the Zanmei world...

Good news, I was killed by a train at home.

Even better news: he's become the navigator of the train.

Utaha, Artoria, Aponia, Misaki Shokuhou, Kuroyukihime, Yoru, Shizuku Misato, Asuna, Genro, and many more—all come to me! Give me a bunch of beautiful women, and I can create a nation!
