When an era is romanticized, it signifies its complete passing. For Chen Junqian, a struggling children's literature writer who remains a mediocre figure despite years of effort, he'd rather be reborn into his familiar yet alien childhood than travel to a supposedly wonderful but unrealistic two-dimensional world. However, the condition is that he must create the best romantic comedy in this most realistic and mundane world, starting in 2009. Lacking a childhood friend with maxed-out affection, he'll artificially create the perfect one. Without a gentle and considerate older sister next door, he'll try to hold onto the online romance offline. Forced to become the male protagonist of a romantic comedy, his task is to recapture the lost opportunities of his past life. If there are no events, create them; if there are no stories, create them. This book is definitely not a guide to rebirth in the new millennium, but I guarantee it will be one of the best time machines ever made.

Listening to the system's repeated prompts and those ridiculous training tasks, Yudian felt immense pressure! However, after defeating Whitebeard with a single punch, the force of his punch blowing away Shiki, and his power intimidating Roger, he realized that his previous hellish training was indeed worthwhile.

I, Uchiha Hofu, accidentally traveled to the world of Naruto.

I obtained the Multiverse Sign-in System! And I got the SSR-level treasure, the [Herrscher of Reason Core]!

I single-handedly repelled the Iwagakure army!

I led my people to evacuate Konoha and establish our own clan!

I slaughtered the darkness of Konoha—Shimura Danzo!

While chatting and laughing with Ban Ye, we decided the fate of a great nation!

I witnessed the collapse descending upon the ninja world!

I defeated the strongest enemy I have ever encountered—the Herrscher of Water!

I am the current head of the Uchiha clan, the former daimyo of the Land of Water, the five-core herrscher of the Hokage, and the demon god of the end—Uchiha Hatake!

The Otsutsuki arrives in high spirits, only to be brutally beaten by an ordinary Uchiha Jonin. That would be quite a sight!

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."

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