The teacher wanted him to accompany Ji Zixuan and Murong Xue, so Zhao Xing inquired about the backgrounds of the two.
Ji Zixuan was a member of the royal family, so theoretically, it should have been easy to investigate. Just flipping through the royal family genealogies would suffice.
In reality, it was quite troublesome because Ji Zixuan did not have any titles; she wasn't even a princess. Considering how vast the Great Zhou's royal family was, it took Zhao Xing half an hour in the Earth Mirror to find her lineage.
Ji Zixuan was the granddaughter of King Chenglan of Cui Xian County in Pinghai State and was not even the legitimate granddaughter. King Chenglan was Emperor Jing's cousin, but their relationship was merely ordinary, as they only shared a common great-grandfather.
Just within King Chenglan's branch, Ji Zixuan had more than two thousand living siblings!
Ji Zixuan had lived for eighteen years, having only seen her grandfather three times before the age of sixteen.
