Even after revealing his true identity, the family didn't say a word about Yu Holea.
Instead, the family asked him why he wanted to know about Yu Holea. They even suspected him as a pervert.
Luo Murong was in dilemma, he couldn't tell the Jiang Family the truth since they weren't someone from the superhuman world.
Since Yu Holea wasn't any criminal, Luo Murong couldn't force them to reveal her true identity so he could only give up on getting an answer from them.
Later he used his connection to know about Yu Holea, but someone was deliberately protecting her information.
When he got to know that 3 major forces were trying to block information about Yu Holea, he could only give up.
Thanks to his daughter who recognized Yu Holea's portrait he had asked someone to make it.
