The two fists collided together. Both of their muscles expanded and looked exaggerated. It was as though all the strength from their bodies left just as quickly as it entered. At the position where they made contact, air flow was formed and turned into shock waves as they were sent backwards at a crazy speed. Clang clang! The loud and dull sound that was generated shook the transparent glasses several metres away incessantly.
Yu Wangyuan's arm numbed instantly as he was sent flying. Soft cracking sounds could be heard from his right fist as a sign that the minor deformations of the bones were recovering. In the aspect of absolute strength, Secondary Acceleration was slightly weaker than the simplified version of the Fighting Formula! Cleary, this was referring to the circumstances when the realm and level of both sides were similar.
