848 World-class Entity

On the top floor of the mansion.

The four people here were busy killing monsters without a second to spare.

Gu Qing Shan still hadn't acted yet.

He calmly observed the situation of the battle.

These 'monsters' were nothing but a bunch of slow and stiff undead.

At a glance, they seemed like the failed products of bottom-level disciples from a third-rate corpse marionette sect.

How could monsters like these bring an entire world towards ruin?

While observing them, Gu Qing Shan seriously contemplated.

He suddenly noticed that some newcomers appeared on the outside of the group of undead.

It was a fleshy giant about 3 meters tall with bulging muscles who didn't budge even after being hit by bullets.

An evolved form.

"Grenade Launcher!" old Li shouted.

The blond man then picked up an RPG set up from the ground, propped it on his shoulder, aimed at the muscle monster and fired.
