Flashbangs—Yang Yi was more accustomed to calling them flash grenades.
Unexpectedly, it wasn't a high-explosive fragmentation grenade but two flashbangs. Yang Yi got hit; his eyes temporarily blinded and his ears buzzing incessantly, unable to hear anything.
Luckily the space in the boxing gym was very large, otherwise, those two flashbangs might have already made Yang Yi pass out.
The enemy's combat skills were very proficient, and the timing of the flashbangs was perfectly controlled. They exploded mid-air just as they were thrown out of the doorway, leaving Yang Yi no chance to dodge. As soon as the flashbangs detonated, gunshots erupted from that doorway.
Zhang Yong's gun went off, followed by Xiao Ran's.
A few seconds later, Yang Yi could start to see blurry shapes; his vision was beginning to recover.
