This was not the first time that Lu Tianzi was facing an opponent who had comprehended the Law of Swords.
Back at the Nine Suns Sect, before they went to attend the Scarlet Moon Heroes Meet, Lu Tianzi had been defeated by a single strike from his senior Nanhuang Jiansheng.
At that time, Nanhuang Jiangsheng had similarly utilised his comprehensions into the Law of Swords to overpower Lu Tianzi.
Lu Tianzi had learnt from that experience, and thought that he would be sufficiently prepared for Chengban's attack.
But at this very moment, he realised that he had been sorely mistaken.
Every single one of the world laws was deep and complex.
Just like how the same combat technique could be interpreted differently by different martial artists, there was also a fundamental difference between Chengban's Law of Swords and Nanhuang Jiangsheng's Law of Swords.
