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..."

………

I have just traveled to the original god, and I have a golden finger. I want to succeed the rock god, and also come with a well-behaved and obedient secretary Gan Yu?

Just when Zhong Rui was about to say that it has never been such a wonderful start, the necessary system for time travelers has officially awakened!

【Ding! Life Simulator is always at your service! 】

【Ding! The dimensional chat group is now open for you! 】

【Ding! Self-discipline makes you stronger. The system is loaded! 】

[The life selection system has awakened! The host is asked to make a choice within thirty seconds, give up the choice, and erase it immediately! 】

Zhong Rui:?

The next second, he took out the body of the life selection system and held it in the palm of his hand.

Zhong Rui: Say it again? (Smile)

Life selection system:? ? ?

Bribing fools to deceive the Queen of Winter, causing the largest and most evil Shura field in the history of the Fire Chaser, exploiting the natives of another world with Kazuma, taking the miserable boss to sunbathe, etc...

Celebrate!

He is a god who combines the power of many systems into one, transcends time and space, and knows the past and the future!

I'm a newbie, so please be patient. I'll read your comments and learn from them. My initial writing may not be very good, but please don't leave yet, it will get better later.

The story of a young man named Su Yun, who was once a captain and wanted to change the tragedy. However, he found that even if he traveled through time, he could not do it, so he decided to implement a plan called [Suicide], ascend to the throne of God, change everything, and reincarnate until he can balance the scales of [Order], create a miracle, and let those girls live the life they once longed for.

Luo Wei obtained a cultivation system, but discovered his current world was unsuitable for cultivation. Deceived by the system, he decided to commit suicide and travel to a more suitable world. However, he instead traveled to a parallel world, Neon Tokyo, where he discovered not only Sanzenin but also chaebols like Shinomiya, Nogizaka, Suzuki, and Nanajo. There were also ghosts, demons, ghouls, vampires, monsters, onmyojis, and gods of disobedience, among a host of other bizarre creatures. More importantly, his cultivation system had failed mid-flight. However, before it vanished, it had left Luo Wei with a treasure trove of techniques and skills specifically designed for cultivation. Luo Wei discovered that the beautiful world of the second dimension was a perfect fit for cultivation. He used monsters to refine flesh-and-blood elixirs that could heal injuries. He used mindless zombies to create flesh-devouring skeletal Taoist soldiers. He used countless ghosts to refine the Ten Thousand Souls Banner, a breathtaking aura of ghostly energy. Thus, Luo Wei, stepping on these monsters, gradually ascended to immortality. My family, who understands? These worlds are truly perfect for a cultivator like me.

Eden traveled through time, but he was not panicked at all. Because this was his second time traveling through time.

The last time, he traveled to an anime world called "Fairy Tail". Unfortunately, he had heard of it but had never seen it...

So he worked hard for six years, relying on the mental power of a traveler and his magical talent, and successfully passed the guild's S-level magician assessment...

And in X784, when he first boarded the Sirius Island as an S-level examiner, he was blown away by the final boss of the whole play, a black dragon that was immune to magic.

Yes, you heard it right, a world of magic, and the final boss is immune to magic, how can you beat him? !

As for this second time traveling, when Eden looked at the man in front of him, who was more than two meters tall and extremely ugly, and kept saying low...

In the endless world, a strange legend circulates: in a special little shop, by signing a contract with the shopkeeper, one can obtain everything they desire—powerful strength, countless riches, and knowledge from another world! But few know that this shop also possesses the power to change destiny, whether past, present, or future, or regardless of race or identity. When they are willing to gamble everything to change their fate, the door to this shop will open for them, and a new destiny will be born here! "Sign a contract with me, and then—transcend destiny!!" — Meanwhile, the shopkeeper, Lan Xing, is looking helplessly at his ever-growing deficit in his account book. He doesn't know when it started, but the number of girls in the shop seems to be increasing: twin oni maids, an elf girl who loves dolls, a cat-eared blade that transforms into a sword… 'The meal expenses have gone up again this month.' He only initially wanted to reciprocate a gentleman's kindness… (Also known as the Dimensional Aid Exchange, Dimensional Oddity Store, Dimensional Exchange…)

[Behind-the-scenes perspective + high-level primordial world + two Hongjuns + Heavenly Dao perspective + no smearing of the Six Sages and other ancient sages!]

Having traversed the primordial world, a mortal encountered the quasi-sage Hongjun. His memories were devoured, while his memories of the Dharma-ending Age were acquired by Hongjun.

(How can a mortal body move a quasi-saint's primordial spirit!)

Heaven issued a decree, and Hongjun proved the Dao with his power. The Three Corpses transformed into Three Venerables, guarding the primordial wilderness.

From then on, the primordial world gained a kind-hearted person named Hongjun who loved to travel the world. He hid behind the scenes to guide the six sages in their cultivation and used the opportunities of the Heavenly Dao to give all races some fun.

Only by delving into and experiencing the great calamity can one understand that the great calamities of the primordial world all stemmed from hatred within the food ecosystem.

After countless epochs, Pangu said to Hongjun, "Fellow Daoist, meeting you in this life is my greatest fortune!"

This book is also known as "Primordial Era: Run! This Hongjun Has a Dual Personality" or "Primordial Era: I am Hongjun, Gods Make Way!"

Bai Tianyu travels through the world of Soman. At the beginning, he activates the chat group system. He obtains the system of the Cosmo God Group. Every time he recruits a Saint, he can activate the corresponding Saint's skills. He begins the journey of building his own sanctuary and collecting the twelve zodiac signs. Busujima Yako: Who can help us? I am willing to give my all. Esdeath: Fight me to your heart's content. As long as you defeat me, you can do whatever you want with me. Alicia: Oh, it's really difficult, but if you can solve the Honkai, I may not be unwilling to serve you. Leone: As long as you help the revolutionary army overthrow the empire, I am willing to give my all. Hill: Me...me too! ... Of course, Bai Tianyu will also find some good talents in his spare time to recruit them into his sanctuary (harem). You are all my wings!

Dongfang Hao transmigrates to the world of Jujutsu Returns to War, awakening the Mangekyou Sharingan at the start, which contains multiple eye techniques: Amaterasu, Kagutsuchi, Kamui, and Tsukuyomi.

His arrival brought an unprecedented boom to the world of sorcery.

During my time at a vocational college.

Gojo Satoru: "I never imagined that besides my six eyes, there would be someone else in this world with a pair of special eyes!"

Xia Youjie: "Because you are Dongfang Hao, you are the strongest. Or is it that you are the strongest, and that is why you are Dongfang Hao?"

Lu Suo: "One Six-Eyed was enough for me, and now there's another one, Dongfang Hao!"

Rime: "Lord Sukuna, you said you would win, didn't you?"

Ye Chang'an was bound to a simulator system. Changing other people's fates could increase the number of simulations, but every time the simulation result was that he would become a Herrscher. "First life, I was in the previous civilization. I grew up with Eden and we even got married. With the frequent Honkai attacks, I thought I could survive with Eden for 50,000 years... but I became the first Herrscher." "Second life, I was in the present civilization. I grew up with Sirin and we were captured and used for experiments. With the injection of Honkai energy, I thought Sirin was going to Herrscher... but I Herrschered first." "Third life, I was in the previous civilization. I grew up in the Far East with the Sakura sisters and became assassin partners with Sakura. With... okay, okay, so I became the third Herrscher too, right?" Every time a Herrscher disaster occurred in the simulation, there was at least one Ye Chang'an among the Herrschers. "System, you better give me an explanation." "...You put too much Honkai energy resistance into it." Ye Chang'an: (￣ー￣) (Three points for the introduction, seven points for the main text)
