That's right, someone as handsome as me must be the protagonist.

[Naruto+Comics+Multiple+Chat Group]

Xu Hui, a time traveler who has only watched Shippuden, travels to the world of Naruto, becomes an abandoned child of the Uchiha clan, and awakens the Rinnegan.

When Uchiha Teru, who thought he had enough free time, was hiding his identity and making trouble in the ninja world all day, a belated invitation came: "Loving Family" invites you to join the group chat.

White-haired Husky: [Family, I found a purple high school girl, she wants to go home with me]

Sanyue is not stupid anymore: [People are in the space station, facing the Doomsday Beast, can they win?]

Cancer of the Earth: [Can someone in the group please pick up the board game cards I just posted in the group and send them to me o( ❛ᴗ❛ )o]

[Group leader] aspires to become the Kanto female champion: [Why is there no lightning-type expert in our group? Ahhhh, Pikachu, please stop electrocuting me.]

Konoha's Three Family Slaves: [You guys are really enjoying chatting with each other]

An ordinary man named Emiya suddenly gains the ability to travel through different worlds. What should he do? Punch Arkham, kick Hydra, destroy Umbrella, beat Cobra, subdue the Decepticons, and destroy the Foot Clan?

Emiya: How many dishes did you have to drink to this extent? If I had any ambition, would I have ended up like this?

In the morning, I went to Totsuki Palace for breakfast. In the morning, I rode Thor to tour the Grand Line. At noon, I took Rem to eat at Ichiraku Ramen. In the afternoon, I drove Gundam and Haruhi Suzumiya for a ride. In the evening, I invited the French village girl to dine at Kikuka-ro.

Isn't this kind of life wonderful?

The cold-hearted Li Xuan brought the sign-in system to the main god space of another world. Compared with other reincarnations, he has the ability to be familiar with the plot.

"Li Xuan is the strongest breathing swordsman in history!" Lord Ubuyashiki Yoya praised him at the Pillar Meeting.

......

"He actually dragged Muzan out to bask in the sun!" The pillars were shocked.

"Why is it so difficult to stop it from being cut?" Li Xuan said to Wuzan, who was stunned and whose life had lost its meaning.

......

In the Sword Art Online world, he directly broke through the 100th floor, and even the GM couldn't stop him.

During the Battle of Marineford, in order to improve his reputation, he beat up the three admirals of the navy, the Whitebeard Pirates, and the Red Hair Pirates.

During the Fourth Shinobi World War, he beat Kaguya like she was bullying a child.

In the Curse War, he used all the spells on himself to eliminate all the weirdness in the world.

Time passed in the blink of an eye, and he stood above all the reincarnations.
