After failing the first few attempts, Wang Zheng wasn't depressed and was even more excited.
When Old Zhuo was back, Wang Zheng was doing a handstand with his fingers. This type of crazy training method for the body truly made Old Zhuo felt a little dumbfounded. Wang Zheng wasn't using Ability X and was doing it purely through the toughness of his body. Disregarding other things, he would likely not have to worry about exhausting his stamina on the battlefield and could definitely fight till the very end with his opponents.
A long time ago, he had also heard of the so-called ancient martial arts that were circulating within the Solar System and the Qi training methods. Honestly speaking, Old Zhuo did not deny the existence of such things but the effects were extremely bad, time-consuming and were complicated. It didn't possess the qualities to be widely promoted. However, he had indeed seen something different from Wang Zheng.
