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."

[Xingqiong Railway Fanfiction] [Daily Taking Care of My Daughter]

Ye Yun traveled to the Xingqiong Railway World and obtained the "Mall of Worlds" system.

Through the system, Ye Yun can sell items from all the heavens and worlds, and can also invite guests from other worlds to the Xingqiong Railway World.

Every time the turnover reaches a certain amount, Ye Yun can get a reward from the system.

The story begins with selling a "coin of destiny" to the Star Core Spirit.

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!

Lin Mo, who traveled to Teyvat, lived on thin ice for sixteen years and successfully activated the system.

However, after seeing the name of the system, Lin Mo fell into deep thought. What the hell is the Bengtie Counterattack System?

You traveled to the Collapse Iron World and struggled to survive for thirty years. After struggling for your entire life, you were unable to find your destiny. When you left Rivet Town, you suddenly saw Clara surrounded by wanderers. What would you choose?

[Option 1: Turn a blind eye. Clara is protected by a suicide bomber. Everything you do is meaningless and will only put you in danger. (Reward: Clara's red coat)]

[Option 2: Draw your sword and help. How dare a mere homeless person bully a barefoot little girl? (Reward: Automated Robot War Dog 1.0)]

[Option 3: Clean up while you're at it. Being able to take care of the homeless while also having a grateful little girl like Clara attached to me is a real steal! (Reward: Clara's Force of Destiny skill branch - [I Want to Help Too]]

Looking at the options that appeared, Lin Mo looked at Klee who was surrounded by Hilichurls in the distance, and immediately fell into deep thought.

Clara = Klee, what about the others? ...

Teyvat suddenly descended upon the [Parallel World Exposure] system.

The world of Teyvat is sunny on the surface, but secretly it is full of regrets and sad destinies that can only be witnessed but cannot be changed.

In the parallel world of Teyvat, under the leadership of the fifth descender Su Bai, the people of Teyvat actually embarked on an expedition to another world and created a world of Teyvat where the power of gods is everywhere.

Nashida: "I was able to conquer a world? But I finally saw the living Great Mercy Tree King."

Lei Dianying: "Raiden Mei, she is indeed very powerful."

Walnut: "I am the King of Hell, controlling the reincarnation of all souls in the world?"

Ying: "Damn it, we're both Adventers, but the gap between us is so huge?"

Paimon: "Ying, you in the parallel universe have already fallen."

However, while the people of Teyvat were shocked by what Su Bai had done, they were unaware that from the moment the parallel Teyvat expedition was revealed, Su Bai had already begun his expedition to the original Teyvat world. ...

Yi Lin, a genius student from Blue Star, dreams of finding the way to immortality by learning the cultivation methods from ancient books.

He grew up in a low-key manner and became the director of a library, reading and referring to various books every day.

I accidentally traveled to the continent of Teyvat in a game I had played before, "Genshin Impact".

Some big guys are carrying out the Red Revolution here

Some big guys are doing a Renaissance here

Some bigwigs here are in charge of the seven countries and various sectors of government

Some big guys started the industrial revolution here

Some opened shops, some engaged in scientific research, some did beauty work, and some fell in love...

Yi Lin thought of the various Genshin Impact light novels he had read before, and couldn't help but sigh that all the senior time travelers were indeed very talented.

Why don't I come here and try to change the cultivation system?

Genshin Impact, start!

The Teyvat dimensional upgrade plan has officially started!

PS: The plot may undergo major changes. A training craze has been set off in Teyvat and everyone is like a dragon, breaking the original fate of Teyvat and eventually the world will be upgraded!
