To pass the civil service exam to become a space-time guardian, Luo Zijin, a doctoral student from the 22nd century, enters Yu Liangxuan's world with a 21st-century smartphone chip. Her final test is to help Yu Liangxuan carry out his revenge and reclaim the throne before the phone runs out of battery.
The exam requirements are ridiculously strict: if the prince dies, she fails! If she dies, she fails! She has to use every means at her disposal to ensure he safely reclaims the realm to pass.
So she becomes the slave of a twisted prince on a dark island, laboring by day and playing his “beloved consort” by night. But his System is powerful and cool, while the antique phone she brought along is both silly and adorable. Ask it something important, and it might even crash! To get through this exam, Luo Zijin has to put up with the phone's stupidity and make do with her own terrible acting.
Whether she's acting coy doesn't matter. What counts is that we refuse to lose!
He's just a little twisted, disabled prince. A children's encyclopedia is all it takes to deal with him!
After the exam, however, the emperor, who has captivated everyone, clings to Luo Zijin day and night, demanding she bear him a child!
Just you wait, civil service exam for space-time guardians.
