That night, Bai Zhe placed an enchanted formation around the walls of the house he was staying in before opening the dimensional door to his training cave. He could sense that the mother and son from the Ji Lin family were training, so he checked their qi. He predicted that Feng Tian would be able to reach the sky-qi level soon.
"I have to increase my qi power as well." Bai Zhe took out the Star Eater sword.
He placed qi characters until they turned into a special enchantment that would gather yin power inside so he could use it to balance his power.
Bai Zhe waited until the yin power was enough before starting to swallow qi strengthening medicine. Then he pulled yin and yang power in equal amounts and started to absorb them to his Dantian.
