As Mo Jiawei spoke, he couldn't help but swallow a mouthful of saliva.
He carefully turned his head to look at Fang Heng, even his voice was slightly trembling.
"Fang Heng, it, it's a Tier 5... Tier 5 mutated creature..."
"Chi Chi Chi Chi..."
The group of spiders below seemed to have noticed Fang Heng and the others, and they all turned their heads in their direction.
"Retreat."
Fang Heng quickly closed the door and locked it.
Fortunately, the mutated spiders didn't chase after them.
The two of them fell silent.
Mo Jiawei's heart was beating wildly.
What the hell! That was a Tier 5 creature!
Tier 5!
The mission difficulty jumped another level.
In the Zombie Apocalypse game, Mo Jiawei had heard that the top-tier creature was the Tier 5 Corpse King.
That terrifying monster could destroy a large shelter with hundreds of people by itself!
