about unique legend

what does this line mean: "It is mistaken by others (i. E everyone not his family) as something completely different than it actually is."

what do others interpret his powers are? what is the truth on his powers?

so did he inherited both the power and memories? because I remember someone said that his sister inherited the strength, yang yang inherited the power, and his cousin inherited the memory? I'm so confused.. anyone just translate this damn great novel! 

Is his sister as involved as he is in this world? 

ah, that one stupid challenger who was stupid enough to question him because of his family, lol, that's so funny XDXDXD 

he gave it for his senior's soul, I think. that kinda death reaper asked that for the price of the transaction. didn't chu ming yang learn the song from his weapon-like fairy? 

....hmm.....like when some of his close ones are in danger and he saves them using his power...or something like that...(..wait a minute...just to be clear...does/can he even fight?) 

in season 2 whos the little kid iv seen on the cover with the main reading a book or something in the forest with a kid with him 

He does go into a sorta comma. If you can call it that...

Mind linked? Mnn, something that was explained yet lost in mtl. It's all the fault of Google mtl...

Also, no need for spoiler tags. This is part of the spoiler section of forum. Anyone who doesn't want to read spoilers shouldn't be here. 

does Senior's identity as a prince come into a play in the novel?

Also how does the mc react when he finds out his sister is part of the world?
(does she beat him up for not telling her?)
