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."

[Zombies] + [Beauties] + [Supplies] + [Infinite Duplication] + [Decisive Killing]

A global catastrophe, the apocalypse descends.

Lin Qin returns to the moment before the end of the world and starts off with the Infinite Duplication System. With just a single item, he can endlessly replicate and generate countless copies:

A piece of beef → replicate → ∞ beef

A bullet → replicate → ∞ bullets

A Gatling gun → replicate → ∞ Gatling guns

...

From priceless treasures to everyday necessities like firewood, rice, oil, and salt—just a single touch from Lin Qin, and he can possess an unlimited amount.

"I've got tons of supplies—it's only reasonable to support a few goddesses, right?"
