"Grandpa, this martial skill is called 'thousand legs'. It's heaven-defying! The first form of a martial skill was twice the power of a normal martial skill. As the level increased, each form would be equivalent to a normal martial skill plus one form. In other words, one form was equivalent to two forms, two forms were equivalent to three forms, three forms were equivalent to four forms, and so on. The most important thing is that the second form can activate two martial skills at the same time. This martial skill is called 'thousand legs' because of this meaning. The first form can activate one leg, the second form can activate two legs, the third form can activate three legs, and so on!" Qibing explained.
