MTL - Metropolitan System - Chapter 16 Is this about?

Upon waking up, Lu Yuan discovered that he had been reborn ten years into the past. Consequently, Lu Yuan sold off all the assets left by his parents, gaining the reputation as the most prodigal second-generation rich kid in the financial world.Little did anyone know that the “rip-offs” he bought would evolve into supreme Dao Artifacts three months later.

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

“The host has come to the days of your old pretending.”

Chen Mo was stunned for a moment, and put down the polished Shiwang drive in his hand.

“It’s time.”

After finishing speaking, Chen Mo came to an empty square, took out the divine light stick and shouted loudly: “Dija!”

…

Yukino Yukino: “My turn, draw a card!”

Kasumi Hill Shiyu: “theworld!”

Eri Sawamura: “Henshin!”

Kaguya Shinomiya: “This is an equivalent exchange!”

Kato Megumi: “Walking in the dark, serving the light, everything is empty, everything is allowed!”

…

Why is the flower of the high mountain of the academy addicted to playing cards? Why did famous fiction writers twist in strange poses? Why are famous painters in the industry inseparable from toys? Why do rich daughters believe in alchemy? Why do ordinary passers-by wear cloaks?

And why did Yangyang Huaxia frequently appear in the Xiuxian sect?

Looking at this gradually becoming strange world, Chen Mo said that all this has nothing to do with him.
