Yes, thanks he-man!!
It is a nice story combined with your speedy translation...
Everytime I read about Qin Yu's dan tian problem, I always thinking of Duan Yu from Demi God Semi Devil (Jin Yong)...
Duan Yu can absorb other people's energy and increasing his own energy because of the skill that he learned.
Qin Yu seems to be able to absorb energy from the universe.. and then take some of them to strengthen his bodies..
I wonder if he later will learn to absorb internal energy from other people as well, instead from meditation.. that will make him quite powerful. He will be too quick compared to other Internal Energy users, because he trained his agility to max, somehow get quickly behind the opponent and lock him and start using his skills..
I imagine that as soon as the opponent lost their internal energy, they will be useless.., while Qin Yu bodies will become stronger, means tougher, faster, etc..
I think I read too much stories these days to come up with those imagination..
