Euri was quite passionate about wanting to become a perfect corporate slave.But after being forced to explore the sentient game infesting his miniscreen, Euri realized that he had stumbled upon an opportunity anyone on the planet would kill for. While the entire human civilization on Planet Nen struggled to deal with the superior lifeforms plaguing the extraterrestrial planes beyond their world, Euri could compete with them all for power by just playing this game!A side-gig that didn’t conflict with his dream of climbing the corporate ladder—how generous can fortune be to bequeath this opportunity to him.Transcending the spatial laws, transcending human notion of cultivation, transcending the rules of Cosmic Development Bureau, Euri began a series of crazy experiments that could perhaps destroy the millennia-spanning schemes of the most advanced civilizations controlling the macrocosm.When interrogated about this fiasco, Euri answered the way a perfect corporate slave should. “Full credit for this goes to my boss, who provided me with the opportunity...”

After all the effort of climbing from a mere daughter of a concubine to the Crown Prince’s consort, before the veil was even lifted, I had become a “flower vase” actress!

Su Shen: “What? Acting?”

The people in the entertainment industry discovered something strange. The “flower vase” girl with the terrible acting suddenly improved! She was also proficient in all of the four arts (zither, Go, calligraphy, painting)!???

Host: Miss Su, there have been rumours that Film Emperor Xie refused to act in this drama because your acting skills are not up to par. Do these rumours reflect your real-life relationship with him? Do you two not get along?

Su Shen: These rumours are all groundless, made up by netizens. He is a very good senior of mine and has given me many suggestions to improve on my acting. We do get along (smile).

Host: Then let’s contact Xie Yan on site.

The phone connected with a “beep”, and a lazy male voice suddenly came through, “When are you coming home, I’m hungry.”

Host: ???!!!

Audience: !!!!!!!!

Su Shen: ╮（╯＿╰）╭
