Qi is separated into nine layers. With every increase of one layer, his strength is increased by a thousand jin. Right now, he is in the sixth Qi layer and possesses the strength of 6000jin. And if he uses the martial technique “Nine heavy waves” which he has trained till the sixth wave, he would be able to send out a force of 6500jin. However, it was still not enough to Lin Feng. If he was able to practise till the seventh wave, with one fierce wave after another bursting out, at that point he would be able to send out a force of 7000jin which would be equivalent to the pure strength of a warrior in the seventh Qi layer.
