Who Says a Sickly Girl Can't Defeat the Weird?

After traveling through time and space into a strange doomsday world and becoming a sickly beautiful girl who needs to rely on a wheelchair to travel, Shen Qiyin gained the ability to upgrade items.

[Gun-shaped pendant + upgrade = Exorcist's holy spear! ]

[Ordinary ring + black agate + upgrade = Gaze of the abyss! ]

[Old pocket watch + parchment + upgrade = Guidance of the old evil god...]

Shen Qiyin looked at the wheelchair under her, and the corners of her mouth began to rise wildly.

...

When the giant shadow of death from the deep sea swept across the last wall of hope for mankind, the doomsday mecha called "Demon King" fell from the sky, and a sin-piercing bullet pierced the giant shadow's head!

In the cockpit, Shen Qiyin looked at the prompt ["Electric Wheelchair" has been advanced to "Satan Yeer"], and couldn't help but think:

"What should I upgrade next... Horus?"
