This transformation stopped after about ten days.
It wasn't because they had successfully transformed their legions. The fishmen had come looking for death again.
This time, the fishmen had learned from their previous experience. They didn't head straight for Liu Zhi's Main City. Instead, they surrounded his island from all directions. It was clear they wanted to trap Liu Zhi on the island, then gradually devour his forces.

The legions formed this way would have obvious weaknesses.
So they needed to add some ranged undead troops.
Only then did the slower-to-react heroes catch on. By the time they tried to find partners and see if they could form legions, it was already too late.
