Lu Yang guessed.
This surge of sudden energy, which could directly enhance the total volume of Xuan Yang Genuine Energy.
Must be Tan Yajing's virgin Pure Yin Qi!
Therefore, if he pierced a virgin.
Then damn, the Xuan Yang Genuine Energy volume could be directly increased without going through the transport and circulation process!
To confirm this, all he needed to do was to try with Lin Qinglan.
If it really is so...
Well, Lu Yang found that, even if it were true, it seemed there wasn't a way to specifically seek out virgins to do so.
First, he wasn't the type to just pierce that membrane to absorb energy, he wasn't without any bottom line at all.
Secondly, he feared that even with virgins, there would still be a threshold requirement on his side.
Thirdly, in today's society, even among girls under eighteen years old, the proportion of virgins is pitifully low.
Hence, this was the type that would be the icing on the cake.
