Still, Qin Feng was not satisfied.
"I have so many gaea crystals and I'm stopping when my dantian has only grown twice as huge? How is that enough?"
"Those overpowered geniuses at Dragon Capital… all of them have dantians that are several times stronger than this. I've even heard that in some powerful ancient warrior families, they even have their own unique, powerful neigong secret techniques!"
"They had to train since they were three years old. They had started training their neigong techniques. Most of them have already trained for ten years when they reached 16 years of age and ascended to D-tier. Their dantian could store several times more internal energy than any mere ancient warrior!"
Qin Feng, on the other hand, came from one of the satellite towns in an underdeveloped city. It was quite rare for them to have any D-tier aptitude user; but whenever there was any aptitude user rising up, those tended to be really powerful.
