Good news: Nakano Yuri has received the golden touch of hard work paying off.

Bad news: This is just an ordinary world. I thought I was going to live a peaceful life as a dragon king, a literary master, or something similar.

But unexpectedly, he joined the multiverse chat group.

Thus, the worlds welcomed a great demon king who defied the heavens.

Give him a breathing technique, and he mastered it on the spot, innovated upon it, and won over Kanroji Mitsuri;

Give him a gentle punch, and he will master it on the spot, thus conquering Kaguya Otsutsuki.

Give him a Devil Fruit, and he immediately understands its essence and masters countless fruit abilities;

At the end of the cycle of hard work and perseverance, Nakano Yuri transcends multiple realms and becomes the strongest being in the world of crossover anime.

When everyone asked him why he had become so strong so quickly, Nakano Yuri replied, "You reap what you sow. Just work as hard as I have!"

(Currently, the world's most popular anime and manga series include One Piece, Naruto, Demon Slayer, Date A Live, and Konosuba.)

When Aoki Hiroshi found himself transmigrated into a seemingly ordinary anime crossover world—only to discover his "cheat ability" was the infamous Gene Lock—he could only sigh in exasperation.

Fortunately, fate granted him a multiverse-traveling power, allowing him to hop between supernatural worlds and accumulate their powers. Meanwhile, his "normal" world began its own spiritual awakening…

Yotsuya Miko: "So many evil spirits… Thank goodness Aoki-kun is here!"

Sawamura Eriri: "Wait—I have King Arthur’s bloodline?! And King Arthur was a WOMAN?!"

Senjougahara Hitagi: "You solved my problem like a hero. Is it so strange to fall for you, Aoki-kun?"

Tsuchimiya Tōko: "To think someone in this era could rival the gods… It’s an honor to meet you, Lord Aoki."

After traveling to the world of anime, Hikage Miyauchi obtained a magical diary. As long as he wrote in it every day, he would get rewards.

But he had read diary online before traveling, and he knew that what he wrote would most likely be seen by the heroines of this world.

As a salted fish with no ambition, Hikage Miyauchi immediately decided to be a pure fun person in this world.

"What era is it? Who still writes traditional diaries?"

"No one is really willing to write their true feelings in a diary and then be watched by countless heroines, right?"

"My mother told me that this world is very dangerous. Boys must protect their privacy when they go out, so don't think about coming to me. After all, I am a man you will never get."

As Hikage Miyauchi continued to write in his diary, an "Avengers Alliance" composed of heroines who could see Hikage Miyauchi's diary was quietly born.

They gathered together for only one purpose, that is, to find the owner of this diary and ravage him inhumanely!

As the first reincarnation, Mo Yan not only survives in an endless world but also creates an eternal kingdom. With a fate system fused into his body, he gathers lovers, allies, and powers from countless dimensions.

[Ding! It is detected that the reincarnation A/A1 is the first reincarnation, and preferential treatment is given. 】

[Policy 1: Since the reincarnation space is newly created and there are no optional worlds, the authorized reincarnation A/A1 can choose the time of descent before entering the mission world. ]

[Policy 2: In order to encourage Reincarnator A/A1 to incorporate various worlds into the Reincarnation Space, Reincarnator A/A1 is given eternal life and the ability to freely adjust his appearance and age. When Reincarnator A/A1's points are negative, no penalty will be given.]

[Policy 3: When the world incorporated by the Samsara Space reaches the minimum requirements for the complete opening of the Samsara Space, the Samsara A/A1 can formulate the Samsara Space's policies for other Samsara within the scope of authority.]

[Policy 4: When giving reincarnation A/A1 to enter the mission copy, they can choose the camp at will, and it will not cause the camp mission of the previous camp to fail. ]

【Note: The preferential policy is only available to reincarnation A/A1. 】

It was not until Moyan was selected by the reincarnation space and passed through that a trace of energy overflowed from the chaotic turbulence between the worlds, which activated the system.
