Arknights, Sai Mian Xiao Shen Ke's Battle Against the Pink-Haired Brainwashing Demon

Whoa~ Oh my god! On my very first mission, I actually ended up in this hardcore land that doesn't cater to otaku? The difficulty setting is hell right from the start!!!

Wen Xuan is a transmigrator, but instead of becoming a transmigrator, he went to the Cyber Myanmar Anti-Fraud Bureau for advanced training and became an entity much like a System. On this mission, he became the Doctor's guardian spirit, or perhaps a System.

"Doctor, they all have lives of their own."

"Their lives don't revolve around you."

"You are not the protagonist of this world."

"Me? My goal is simple: to help you escape that pitiful fate of being a rock-throwing goblin and become the Shenshan Shawshank."
