[ps: Don’t join Ron’s party, I don’t like this character]

My name is Leggett Black.

After crossing over, I obtained a system....

It was also from this day that the world began to emit shrill screams.

Tang: Damn it, who stole my true energy!!!

Yu: "Ahhhhhhhhhhh!!! Oh my god!!!"

Jia Zhang: "Old Jia, please come back and take this thief away!!!"

In short, this is a story about exchanging everything in the Harry Potter world...

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."

Lu Yuan traveled to a supernatural world full of ferocious beasts.

Just as Lu Yuan thought, at the awakening ceremony, what awakened before the supernatural power was the system that the time traveler must have!

The system not only grants him rare superpowers, but also provides him with the opportunity to become stronger by killing monsters!

However, the supernatural attributes issued by the system seem to be a little bit wrong?

I'm a grown man, and you asked me to play an ice-type character?

However, the law of true fragrance may be late, but it will definitely not be absent!

There is control and there is explosion, who can not love this?

When Lu Yuan pushed forward all the way in the future and was even able to freeze time and space, he sighed: "It turns out that the ice system is the invincible path!"

[Everyone travels through time + villain + online game style + game world + decisive killing + lone wolf + no female protagonist]

(This book is rather dark. The protagonist develops rapidly in the early stage and begins to conduct research in the middle stage.)

(The villains and the good guys all have high IQ and powerful weapons, and there is no traditional cool protagonist who quickly destroys the world.)

(The Magic Continent is just a small map at the beginning, and the Starry Sky in the later stages.)

When the blood-red sky covered the blue planet, 8 billion people were forced to step into the meat grinder of the Game of All Worlds!

While everyone was ecstatic about awakening their S-level talent, Xie Xun hid his SSS-level talent [Analytical Brain] deep in his heart—he chose the hidden profession [Wizard]. As long as he had enough knowledge, he could instantly dismantle the essence of everything.

There is no Madonna-style salvation here, only a throne built with wisdom and madness.

When the righteous players shouted and charged for justice, and the villain BOSS was hiding murderous plans, Xie Xun was standing at the top of the food chain and sneered: Brain of Analysis, start!

[Hint: Analysis successful, you have gained special abilities...]
