Travel through a world invaded by disasters and awaken the sign-in system of all worlds.

He thought that signing in in this world and obtaining the power of a Ruler of Reason, which was enough for him to protect himself, would be great enough.

Unexpectedly, he was selected by the dimensional chat group and got the opportunity to sign in to other worlds!

[Ding! Congratulations to the host for signing in to the Genshin World and gaining the allegiance of the Heavenly Principle and the Four Shadows of Heaven.]

[Ding! Congratulations to the host for signing in to Demon Slayer World and obtaining the perfect version of the immortal body, which cannot be erased by non-rule levels.]

[Ding! Congratulations to the host...]

Sign in to all realms, strengthen yourself, establish destiny and reverse entropy in the gradually collapsing world.

I originally wanted to head towards the end of the trees and the sea, but I found that I met countless beauties in the process.

Kasumi no Shi: "Tsk, what an unlovable leader!"

"You left a deep impression by being a hero saving a beautiful girl, but now you want to just walk away after you've been seduced?"

Eriri: "Damn it! I was here first, and the twin tails were supposed to increase attack speed! Why don't you come up and attack!"

Esdeath: "This man is stronger than me. I can't match him in terms of strength, but I must conquer him in other aspects!"

Lei Movie: "He saved his sister, if he wanted to..."

………

Quit the band and become a star god?!

Baili, who had traveled to the world of Zongman, decided to create a few Destiny Envoys with the help of the system.

However, the 'Starry Sky Train' that the system had snatched away kept receiving 'signals' from another world.

then--

Chaos Expansion: Clear the maze in the world of "Di Mistake"!

Chaos Destruction: Rias from "High School" becomes a Commander!

Chaos Harmony: Form a band for life, and then crush and destroy creation!

When the fate of chaos flows through planes such as "Hokei", "God Slayer", "Black Bullet", and "Azur Lane", everyone feels the glance of God!

Baili has only one explanation for his fate: what's yours is mine, and what's mine is still mine!

The time traveler vowed to meet the Demon King of Time by chance, and under his entrustment, he began to re-enact the history of Kamen Rider in various worlds and save and repair the Kamen Rider world.

Time flew by, and Chen vowed to complete his mission and became the second demon king. He used the demon power that he had just obtained and was still warm to restore the world that he had made a mess. He found a secluded place to prepare. Start your own retirement life in an abandoned house.

Then, he realized that something was wrong. A mysterious video platform appeared in each world.

Itsuka Shiori: I am the Promised Superman in the future?

Kousaka Kyosuke: Belt-san! Run another lap with me!

Emperor of the East China Sea: The president said that I am an undefeated emperor who shines like the sun rising from the sea.

Amiya: Woohoo, doctor, leave the fate of the world to me!

Kiana: How come there is this guy named Chen Shi in every world?

Cold sweat ran across Chen Xiao's forehead.

Damn it, who is plotting against me?

Li Zuoyi, a commander, was touring the base with new recruit Nikki. "Darling, did you recruit that Nikki too? She's... a bit of an eyesore." "Commander, the three dormitories at the outpost are almost full... If you really need anything, I can help." "My dear, you belong to me alone. Hehe, I really can't leave you here alone..." "Commander! Didn't you say you wouldn't bring anyone here anymore? Eh? It's not that I care about you, it's just... it's just..." Sweating profusely, Li Zuoyi shrugged off Nikki, who had various ideas about him. Escaping such situations had become a daily routine for him. Stepping into the darkness, Li Zuoyi approached an Ark high-ranking officer, unsheathing the longsword at his waist. The blade flashed with a cold light, his eyes ruthless: "I'm here for revenge." "Ah? You said we had no grudges?" "You have such a bad memory. A hundred years ago, you abandoned me and the Goddess Corps. Do you think you can just let it go?" Eliminating those who had betrayed him was also a daily routine for him.

Transmigrating to the world of anime, the system rewards a complete set of Devil Fruits. First, recruiting a small helper made of binchotan charcoal. Then, looking at the familiar anime heroines from his past life, Xia Tian says he just wants a sweet everyday life. Yukinoshita Yukino, Yui, Miyazono Kaoru, and why is there also Mrs. Fueguchi Ryoko, Touka, and Miko? Whether you're ghouls, monsters, or evil spirits, if you don't let me live my normal life, I'll destroy you all with a thunderclap. Setting up a random stall, how could it have ended up in Beika Street, Yahara, and the pitch-black Tokyo? Natsume Reiko, a loli blinded by the enterovirus, is a warm and caring person. Xia Tian respects the fate of others, but will intervene when he sees someone unhappy.

More than ten years ago, a child fell from the sky in front of the Rock King. When Morax saw the child, he frowned for a long time: "What an ugly child..."

More than ten years ago, Zhong Gui fell from the sky. The first person he saw when he opened his eyes, and the first thing he said was that he was jealous of her beauty. Zhong Gui was determined to stick to him for the rest of her life, eating and drinking his food, and even eating him out of money!

Everything was going smoothly until Zhong Gui returned from his travels in the seven kingdoms.

Zhong Gui: Am I engaged?

Ganyu: When did this happen? How come I have a new fiancé?

Shen He: Senior sister? Why is she here?

Hu Tao: This is my adopted husband. Where did you come from? Zhongli, Zhongli, they're bullying me!

…

Then, you need a tool to travel to other worlds!

Chat Man: Here I come!

"Congratulations on rescuing ten people, earning 10 points." Mo Changge gazed at the mummified remains of corpses beneath his feet, lost in confusion. "Congratulations on obtaining food and water necessary for survival under extremely harsh conditions, earning 5,000 points." At the outpost, Mo Changge stared blankly at the mountain of supplies. "Congratulations on finding temporary shelter, earning 10,000 points." In the Ark's luxurious villa, Mo Changge, sipping fine red wine, looked bewildered. "Congratulations on defeating the Tyrant-class Letcher, earning 20,000 points." In the desolate wilderness, Mo Changge stared in amazement at the weathered and battered Letcher beneath his feet. Are you sure this is apocalypse survival? A century has passed, and order has returned to normal, yet the system remains at the dawn of the apocalypse. Things that were scarce at the beginning are now readily available. Furthermore... The ultimate goal: liberate Nikki!

Xu Xuan traveled to the Perfect World and, after 900,000 years, finally achieved immortality.

Upon reaching immortality, he was pulled into a martial arts chat group.

"I'm already an immortal, what's the use of this chat group?"

"This crappy cheat code is 900,000 years too late!"

Fortunately, the chat group can locate the coordinates of the heavens and even upgrade.

Using these coordinates, Xu Xuan gradually opened up the cycle of reincarnation and established order in the heavens, ultimately setting foot on the sacrificial path.

(There are multiple female protagonists, and their personalities will try to be consistent with the original settings. I won’t just pick them up without thinking, but I will pick them up if I like them.)

(Before each world begins, everyone's opinions will be collected. So please leave a message in advance about which heroines you would like to include and we will try our best to arrange it.)

(The introduction is weak, I don’t understand operations, and I can’t grasp the key points. I was fooled by my friends to start a book, and I can only write and write.)

Traveling through the heavens and the worlds just to fulfill the original dream.
