[Upgrade + Cthulhu]

Having transmigrated to Tokyo in a parallel world, Lin Taiyu is under immense pressure.

He has an exceptionally beautiful girlfriend, but only Lin Taiyu can see her. His girlfriend always tries various methods to test whether Lin Taiyu can see her.

There was a lady named Mary who kept calling Lin Taiyu, threatening to kill him. Even if Lin Taiyu didn't answer, her phone would automatically ring.

The woman, who was eight feet tall, would often knock on Lin Taiyu's window in the middle of the night to ask if he was home.

The wives and young girls he knew were always being targeted by various strange people.

The wealthy woman was nearly torn to pieces by a strange little man in her dream. When she woke up, a strange voice rang in her ears: "You won't wake up again next time."

In the home of the aloof school beauty, her mother, transformed into an evil spirit, seeks to control her.

The ropes holding the human-shaped balloons would occasionally fall from the sky.

A gigantic water demon roamed the city unseen by anyone.

The world is sick.

Lin Taiyu intends to use the Flame Fist to cure his illness.
