In the first place he became stronger way too fast after having his enlightenment in the painting. I understand that was what the painting was meant for but his own brother that spent years training before him is noticeably weaker thna him??

In the first place he was incredibly more powerful than his brother. He might have lost in terms of battle power at first, but his perception is quite incredible, so he was able to get an enlightenment. I also think that not only the painting save his life, but little by little he was able to gather enough mana even though he was originally physically weak. Let's just say that his container is a little bit bigger than his twin brother who cultivated for years. They're both talented, but in different areas.

It's been said that why was he agile when he was little but when he got older he was weak. it is because the energy opposes each other? (no one survives the age of 20 years). The elder gave him the painting and he recovered. Of course he is more powerful than the younger brother. Remember he had elder his younger brother had not.
With the way Ahram’s looking at MC can she also read minds as a special ability? Or am I just overthinking this?
Maybe something that's related to being able to read people?
