Chapter 650: Cap 648: Zenos causes a Wave of Monsters part 8

Pov Hela: 

Morning of the 5th day of the Monster Wave. 

Today has been a strange day, the number of monsters has increased, but their strength, in general has decreased, this means that it is easier to fight the Monster Wave as we have people capable of clearing large groups of monsters quickly like Érica with her area spells, Irina with the creative way she uses her corrosion ability and Jade with her venom even deadlier than the venomous monsters we've been fighting. 

The master trusted me to deal with most enemies knowing I could turn dead monsters into Undead slaves to fight on my command, which went terribly wrong when I tried it on the first day of Monster Wave. 

The monsters I turned into Undead got out of my control, and the energies in this forest and this village are out of control, this is affecting my spells to control Undead, which makes me just create more monsters that we will have to defeat.
