Sheyan and Sanzi stepped into the core zone of the prison where the dangerous criminals were kept. The zone was built in a "回" shape, with a rectangular corridor. There was only one entrance, and anyone who wished to enter or leave the zone must pass through the entrance. It was now the zone's last line of defence.
Sheyan and Sanzi were forced back by at least a dozen guns as soon as they appeared. Of course, bullets were not a strong threat to Sheyan, but the three taser gun shots mixed within were something to be wary of.
The destructive power of the taser gun was already devastating on its own, but what's more frightening was the paralysis effect! If Sheyan was hit by one, he would have to brace himself to get hit by 7 more! That kind of damage was unbearable even for someone like Sheyan who had monstrous vitality. His life may very well be put in danger.
