My name is Ivan, a time traveler, male, with average combat power, and a talent for being funny. However, the mission requires me to kill the immortal demon king, so... I can only be a gigolo!

Selia: Damn it, why is it that every time I have these unnecessary emotions because of you?

flamme: Why didn’t you tell me earlier that you and selia had a child!

frieren: What exactly is this sour feeling in my heart?

frieren: Woohoo, I’m really not a big mushroom...

[Behind the Scenes + Transmigration + Multiverse + Fourth Calamity + System]

What's it like to start as the Heavenly Dao?

Gu Ran wakes up to find himself transformed into the Heavenly Dao of Earth. As events unfold, he learns that a great secret lies hidden behind the seemingly ordinary Earth.

The myths of ancient times are not legends, but true stories that happened in the past.

For various reasons, the ancestral planet shattered and broke into numerous smaller worlds scattered throughout the myriad realms, and Earth was one of the original fragments.

As our understanding of the laws of nature deepens, the unique characteristics of Earth begin to emerge.

Earth is a core fragment of the ancestral planet, capable of continuously devouring other worlds to strengthen itself. Thus, Gu Ran embarked on a path of plundering the heavens.

World War? How about the Fourth Calamity?

A chosen one? Send a transmigrator there, give him a system, seize his fortune, and destroy his destiny.

One after another, transmigrators were sent by Gu Ran to various worlds. Many years later, Earth was besieged by many worlds.

Gu Ran calmly sent a message to the transmigrators from various worlds: Our ancestral planet is in danger, you must return immediately!

Transmigrator Number One: What! It's been so long since I left home, it's time to go back and visit!

Transmigrator Number Two: Anyone who dares to bully my ancestral star, no matter how far away, will be punished!

………………

As the various transmigrators were recalled, the myriad realms watched as powerful beings stood in the void above Earth, looking as if they had seen a ghost.

The army of time travelers: Are you the ones who have offended our ancestral planet?

As the words fell, world after world crumbled and transformed into primordial power to nourish the Earth.

Gu Ran looked pleased: "You're such a good child, you've all grown up..."

I, Lin Yuan, will marry the most beautiful woman and pilot the best mobile suit.

After more than twenty years of rigorous training in ancient martial arts, he has been reborn! The good news is that he has been reborn into the world of his beloved SEED Gundam, but the problem is that his martial prowess is of little use in this world.

After awakening his past life memories, Cui Yunzhou finds himself transmigrated into the world of the Dragon Clan, possessing an S-rank bloodline. He knew that the Blood Sorrow would bring an invitation, but he never expected it to be… [Do you want to understand the meaning of life? Do you want to truly… live?] "An invitation from the Supreme God?" He thought this was unexpected enough, but then… looking at his teammates: the Uchiha brat, Dio the beast, the Bleach elementary school student, the passing knight… Cui Yunzhou smiles. Worlds: One Piece, Dragon Clan, Fusion Terror: Gonjiam.

Note that this book references the Naruto manga, and the author will not maliciously portray Sakura or Hinata; everything is written according to Kishimoto's description.

The system's presence gradually weakens in the later stages, and it's not adept at using the system to advance the plot.

Note that slice-of-life scenes are interspersed within the main storyline of this book. If you only want to see the protagonist killing, you can skip this one.

Note that this book does not have a single female protagonist.

In an unexpected turn of events, Yusuke Hanyu finds himself transported to Konoha.

With average taijutsu, ninjutsu, and genjutsu skills, he realized after several years of hard work that he wasn't cut out for these things and chose to give up, but unexpectedly became bound to the Scroll King System.

With hard work, you can become stronger. Want to just lie back and relax? Sorry, how about some electric shocks from the new energy system?

Is a system that can't add points or give items from another world really necessary? Yusuke asked himself this question countless nights as he worked hard.

Many years later.

The Fourth Shinobi World War has begun. Madara Uchiha stands atop a mountain peak, arms crossed, head bowed to the Allied Shinobi Forces: "Do you wish to dance?"

Yusuke, who had just finished his taijutsu training, rushed to the battlefield: "By the way... I'm not late, am I? Sorry, I'm in a hurry. I have ninjutsu training at 3 PM this afternoon, so can this battle be kept under two hours?"

Yusuke Hanyu: "I just want to lie down!!!"

Upon waking up, Kitahara Kaede found himself transported to the Naruto world. He initially thought he'd spend his life as a cannon fodder Chunin, but unexpectedly, he awakened a diary system! By recording in his diary, he could easily access various bloodlines, ninjutsu, and divine artifacts. However, he gradually noticed that the world's style was becoming increasingly strange. Why did Uchiha Sasuke awaken the Sharingan ahead of time? Why did Uzumaki Naruto master Sage Mode beforehand? How come Uchiha Itachi was still alive and well? How come the Otsutsuki clan had arrived so early? Uchiha Sasuke: This time, I'll be Hokage! Jiraiya: This time, I won't die at Nagato's hands! Uchiha Itachi: I'll help Sasuke clear all obstacles! Hatake Kakashi: I'm never going to be a 50/50 player again! The style of this world is getting weirder and weirder.

After traversing the Gu Realm, Fang Xiaoyuan became an outer disciple of the Blood Saint Sect, a sect of the Blood Path.

The internal situation of the Demonic Sect is turbulent and unpredictable, with fellow disciples scheming and plotting against each other.

With his low aptitude and lack of background, Fang Xiaoyuan faced even greater difficulties within the Blood Saint Sect.

Just when Fang Xiaoyuan was feeling utterly hopeless, the long-awaited Multiverse Chat Group finally arrived, and all the worlds where the group members lived became resources for his growth.

As a typical otaku on Earth, I woke up to an unfamiliar ceiling and the system's voice in my ear, not knowing what to do.

Shiori: You've helped me so much, I don't know how to repay you.
