Anyway, they were still trapped on the first floor, and the number of zombie clones was already saturated.
He decided not to level up for the time being. He could save a large number of zombie clones for emergencies.

Based on his past experience, he would most likely require a Tier 3 mutation crystal for his next upgrade.
At least for now, he had yet to find a way to obtain the Tier 3 mutation crystal.
Perhaps he would have to farm a commander-level creature to get it.
It was not difficult.
Fang Heng remembered that he had seen the Black Castle using commander-level mechanically modified mutated creatures to attack the federal camp.
At that time, he had also observed it.
The commander-level mutated beast was very strong, but it was not impossible to defeat it.
