Zhao Ya Rou

Pesonality
According to Ye Lang he tested her using psychological questions and she answered all questions correctly. But normal people would't be able to answer even one correctly and the less one answers the better. According to him she is a shrewd, crazy and cold blooded Psychopath.

Plot
She is the 8th Princess.

After Ye Lang ruined the Emperor's selection for the next Emperor/ Crown Prince/Princess he was tasked to give all his children new tests to choose the next Emperor. Ye Lang used psychological questions to chose the next Emperor but she answered all correctly, what he didn't think would occur. Later when the Emperor asked him whom he would choose as the next succesor he said said: those who answered 0 questions correctly or those who answered some questions correctly.

Afterwards he told the Emperor to kill her and rid the Empire of and evil bud, or else the it will be a disaster for the Empire.

But the Emperor couldn't kill her, which led to his own death some years later (or did it?).

Some of the Questions he used:

Some years later during a banquet hosted by the Emperor, her father she killed him and takes his position as the ruler of the Soaring Sky Empire, she become the Empress. She also killed all her siblings outside of her fifth sister, who wasn't there and Princess Qi which she used as an insurrance against Ye Lang. Furthermore almost all the influential figures of the Empire were invited and she poisond them using the seven days and nights poison, which makes them unable to use magic or douqi. She also had a plan B and C and she also used a anti-magic Alchemy formation. But Ye Lang found the poison and warned his family.

In the end everybody submited, outside of the attending Ye Family members. But they were surrounded by soldiers and because of the anti-magic formation nobody could use magic elements and it should have been easy to kill them all. But unexpectedly Ye Lang used inner strength, saved his family and destroyed the formation. In the end they managed to escape and left the Empire, she had to give up. She framed the Ye Family accusing them of having killed the Emperor and her brothers.

So the Ye Family split in 2, one remained in Soaring Sky Empire and the other fled.

She also subdued the chaos after her coronation using bloody tactics.
