Cheng's palm print is taboo for Long Live Lord.
The two of them have a bond of fighting back to back to conquer the world, and he has the final say as to which concubine Long Live will favor.
But after seven years of deep love, he was slapped with a slap in the face, kicked out of the capital, and demoted to the indifferent Mobei to suffer.
For three years, he refused to even write a congratulatory note. It was not until he was assassinated by the Tatars and lost one of his arms that Banzai suddenly realized that he could not let go of others, so he went to pick them up in person without sleep, but what he saw was him hugging others...
Emperor: When have I ever been so groveling to someone?
Cheng Lin: Long live your self-respect, I don't want to serve you anymore.
Purpose: The eunuch's situation is humble enough, but the eunuch's feelings cannot be humble.
