Shinxbi

It's not about whether he was wrong or not. It's about whether his sister was overprotective or not. In her eyes, he's a normal boy who nearly died as he didn't reveal his strength to her.

My guess is that he sealed his memories so that the World's Will won't be able to read those memories as he might've struck a deal with it by providing his knowledge that he will gain in exchange for using so many of the magic crystals

Extremely stupid of him to announce such a critical piece of information just before leaving. It could cause a lot of chaos while he isn't present.

I can be completely wrong but don't stars only have Hydrogen and continuously undergo nuclear fusion to form Helium? A planet, no matter how big, definitely will not be only composed of gases (except Jupiter which I've read somewhere is a failed star).

What's the time limit?

It makes sense then. I thought all of curse continent had a limit to strength due to that miasma

c'mon bro he practices a cultivation manual with all the elements and has used Supreme treasures for all those elements. Also the treasures he has access to are both from and outside of Etherium realm and his physique is at ultimate level which gives him INFINITE MANA. Can even generations of wealth while living at cursed continent come close to that?

Of course now that the empire is getting f*cked by the princes, they will attack and our Prince Charming will save them, get married to the princess and become an emperor
