The system did the same thing at the first junction where they slayed about 10 tier 2 zombies. And the notifications were very useful just as this one was very useful now, at least, he wouldn't have to be afraid if tier 3 zombies were part of the zombies or not.
He knows he wouldn't have to pass through the problem of slaying a zombie, and regeneration or healing would be happening right in front of him. They and the zombies clashed, and the slaying began once again. The first thing Hugo did was swing his sword with force cutting off the head of a certain zombie as blood spilled out and the head flew in the air and landed on the ground.
Another zombie received a stab in the stomach as the sword entered its stomach and came out of the back. Drawing out the sword with force, the zombie's lifeless body fell to the ground. Two zombies gone, the rest would be handled by his friends which they did.
