Vol 14 Chapter 27-3
This was an idea Zheng came up with before the movie, an instant Destruction state. Destruction was powerful but so was the burden it put forth. It was best to leave Destruction for when he was certain of winning unless the fight was one of life and death, such as a fight against his clone. However, many situations required him to use Destruction in reality. If he could use it against the bodyguard bugs at will, he could tear them apart at the joints. He wasn’t confident at tearing through their exoskeleton with his bare hands even in Destruction.
That was why Zheng came up with the idea of instant Destruction!
