223 Greedy Devil

" Han Sen, I hope that you could start to practice Yin Yang Blast right now..." Bai Yishan said quickly.

"Professor I want to ask you something. Why didn't you go find an evolver or surpass her to practice your invention?" asked Han Sen.

"I've thought about it but Yin Yang Blast was based on ruler, and ruler has a requirements for those who practice it, which is the age of them should not be over 20. Although I had made a lot of improvements, the limit is still there. For those over 20, they would make very slow progress in practicing Yin Yang Blast. They could spend 10 years and make less progress than a young person in a few months." Bai Yishan sighed.

"So i'm the most suitable candidate to practice Yin Yang Blast under 20?"

"That's right. Otherwise I wouldn't go to the extreme and try to lie to you." Bai Yishan nodded.

"So I'm your only candidate now?" asked Han Sen.
