Ye Yang, a straight man from Northeast China, transmigrated into a novel about court fights, became a concubine, and was bound to a system, which could put on view the favorability score of the main characters.

On condition that the emperor’s favorability score was too high, he’d fall in love with Ye Yang. However, if his favorability score was too low, he’d be mercilessly killed. In order to protect his life and chastity, Ye Yang forced himself to create his own persona, repeatedly switching between the personality of an unrefined man from Northeast China and the first beauty of the harem.

Yet, things were getting worse and worse. At first, he let the favorability score of the dog emperor drop. Later, the score began increasing rapidly. Watching how the favorability score was about to skyrocket, Ye Yang panicked.

He wore a gold chain and raised a mink, silencing all of the imperial concubines of the harem. Feng Luan’s favorability score had been increased by +1.

He had a snowball fight with the dog emperor and pushed him into a snowdrift. Both of them caught a cold. Feng Luan’s favorability score had been increased by +10.

The mink he raised thought out a plan for Feng Luan to renovate the imperial study room worth of more than 10.000 taels of silver. The imperial study was so horrible that one could hardly bear to look at it.

Feng Luan’s favorability score had been increased by +100.

What’s going on! Are you still a straight man!

……

The longer Ye Yang lived in degradation, the more he felt that the dog emperor was different from what he initially thought.

At his feet the ground was covered in blood and bones, but behind him was the delightful scenery of the prosperous world, and the coming of all nations.

A few years later, he helped Ye Yang up the stairs and gazed into the distance. He saw a myriad of twinkling lights, bustling, bright and beautiful.

And Feng Luan whispered in his ear.

“My dear Imperial Concubine, look.”

“This is our country.”
