When he woke up, he found that he had become the owner of the Wanjie Building and could trade with people with predestined relationships in all the heavens and worlds.

He met Saitama during his first transaction, and after agreeing on a battle with Saitama, he successfully obtained Saitama's limit-breaking training method.

Afterwards, Ye Ming began to trade again and again.

From Murong Fu in Demi-Gods and Semi-Devils, to Duan Lang in the world of Storm Riders, to Zhang Xiaofan in the world of Zhu Xian.

One by one, the characters that once appeared in Ye Ming’s mind came into reality!

Uzumaki Naruto: OP, how many Bankai coins can I trade for the Nine-Tailed Fox? I want to become stronger and find Nibashi!

Vegeta: OP, how can I defeat Kakarot?! I'm Speedy Vegeta! How can I be defeated?!

Gu Yue Fangyuan: Do you have Immortal Gu?

Fang Han: OP, I have a door here. Do you want it?

Han Li: I have a small bottle! Can I exchange it for a Nine Revolutions Golden Pill?

Sun Wukong: OP, please tell me how many Wanjie coins are needed to kill that bald guy Tathagata!

How can we revive him?

Dugu Baitian: Is there anyone who wants to kill the sky with me?

What should I do if I travel through time and space and become a fat otaku?

Masao Tanaka was extremely desperate. He had traveled through time. It would have been fine if his name and family were strangers, and it would have been fine if he hadn't been given a handsome face.

But why did he become a typical fat otaku like someone from an anime?

Fortunately, there is a system, but why is this system called the [Degenerate System]?

······

Yukinoshita Yukino: "It's really uncomfortable to be with Tanaka Jun."

Ying Lili: "You are a guy whose head is full of pornographic garbage. Come up with a new plot for me!"

Kasumigaoka Utaha: "I never thought that the person who wrote such a sweet novel would be you, Fat Otaku."

Yotsuya Miko: "Tanaka, help me, just destroy the evil spirits and let me..."

Fujiwara Chika: "Tanaka is really cute."

Goto Ichiri: "Tanaka, best friend."

At the sacred wedding, the bride and groom accepted the blessings of their family and friends. The newlyweds looked at each other, smiled happily, exchanged a vow kiss, and began their new life amid applause. It should have been like this, but at Lei Luo's wedding... "You, Artoria, can touch me, but I, Artoria, can't?! We're all Artoria, why do you have all the privileges?" "...That's it! Holy Lance, weigh anchor!" "Who's afraid of who! Unnamed Victory Sword!!" "...Excalibur!" "Um, um! I'm sorry! Calibum!" "Wow, even if it was another me, anyone who steals the king's possession deserves death! Excalbur Morgan!" Lei Luo, who should have been the protagonist, could only watch helplessly as his bride and a group of "herself" fought each other.

(Content from the Otherworld) ...Wait a minute. I need to clarify a few things first. First of all...I am the Sensei here, and you...are my 'students'? "Yes." Then what are you doing? What do you mean by "developing a special relationship with Sensei, and there's no turning back"? What do you mean by "spending long matches with Sensei..."? What do you mean by "your heart being stolen by the Phantom Thief of Hearts"? "Isn't this what you've been doing all along, Sensei? Under the guise of 'transactions,' under the pretext of 'deepening bonds,' you steal our hearts with each encounter..." Wait a minute...I'm here to save the world, what are you going to do to me?! [List of Bond Relationships] *Ends at the end of Volume [Scepter]

Beneath this world exist beings called "Monsters," rampaging, roaring, destroying, and breeding despair. And these dangerous things are spreading towards another world. The Demon King no longer fears the sun, the Honkai creates Herrschers beyond their capabilities, the Abyss begins to overturn the laws of nature, and the Witch attempts to devour the Law of the Rings… This situation seems to indicate that the world is gradually heading towards destruction. But! "Who is the one who bears all despair, brings the light of hope with a body of despair, saves countless worlds, and steals the hearts of countless beautiful girls, leaving them unable to forget her?" "That's right! It's me!!!" Miss Black Hope declared. This book is also known as "Clearly a Humanoid Monster Defined as an Ultra-Ultra-Ultra-Dangerous Containment Object, Yet Too Silly" and "Monsters Should Be Scary? Murderous? No! I Want to Create Trouble! I Want to Cause Trouble!" PS: New book uploaded, please support with all kinds of votes. PS: Two older books are already completed, one of which is three million words long. Updates are guaranteed, feel free to collect and read.

Coming to Teyvat as a time traveler? Where is the system?

I have become the world consciousness, and as one of the Seven Gods Chefs, I should save the world!

"Everyone, let's form an alliance for Teyvat!"

"Ye Ze, you are a time traveler!"

No, what kind of development is this? When did I reveal myself?

Can the fate of being swallowed be changed?

What is Teyvat? Teyvat is not a place, it is a civilization. After breaking through destiny, we will head towards the stars!

Dane was reincarnated as a white American kid. He initially thought this was just another ordinary rebirth story, already envisioning how he'd dominate the stock market. That was until one night, as he boarded the subway home, he was taken to a spooky cave... "Hold this scepter and repeat after me, Shazam!" He was stunned. My name isn't Billy Batson, is it? The wizard was even more anxious than I was: "Stop talking nonsense, inherit my power!" What could I do? I could only recite a line of poetry... Years later, Dane, now a multiverse powerhouse, lamented, "Technology and magic—we need to master both, and we need to be strong in both!"

(Slow to warm up, not invincible) After waking up, You Fu, who is about to enter his third year of high school, finds that he has traveled to a parallel world with Pokémon!

…

Oh my god! Isn't this the mythical beast Meltan? Why doesn't anyone want it?

What? They didn't even know Meltan could evolve into Melmetal, thinking it was just a rare, weak Pokémon.

Then I won't be polite... Wait, I don't think I can gather dozens or hundreds of Meltans to evolve...

bite!

What? A Pokémon evolution and training system? Tokens can be exchanged for Meltan candy?

Ahem, sorry about that.

It is our duty to reforge the glory of the mythical beast Meltan of Steel!

(A story with multiple female protagonists is not a happy one, but the ending will be happy, and the protagonist is not extreme.) After traveling to Ionia, the timeline is still very early. The conflict between the two cities has not yet broken out, Noxus's plan to invade Ionia is still being prepared, and Sylas is still imprisoned in a dark dungeon. Faced with Shen, who is not as old-fashioned as he will be in the future, and Jie, who seems aloof, Lin Yu chooses to lead them to steal and rob. Of course, the most important thing is them. Sona: I just want a brother, I don't care about anything else. Xia: I can only feel at ease when I am with you. Irelia: Don't be like this, uh, don't let others find out. When Lin Yu was forced to leave Ionia and go to the entire Runeterra, he suddenly realized that he had unknowingly left so many concerns in Runeterra. Wait, who are you? Syndra: Energy outpouring! Lin Yu:! When did I provoke the ball girl? No, I have never seen Syndra!

(It's a bit toxic in the early stage, please be gentle with your criticism. The writing is not good, so you can only look at the story. I'm a newcomer.)

I traveled through time.

The good news is, I opened a breeding house.

The bad news is that the breeding house is about to go bankrupt.

Are you kidding me? I'm going to be a Pokémon Master.

How could I possibly open a store in this lifetime? Impossible, absolutely impossible!

System "Three legs, three choices?"

Okay, I admit that I just want to open a Pokémon breeding house.
