Bab 663: Unstoppable Rampage!

Even though the monster horde was no longer charging forward as quickly as before, it became sturdier and had thicker defenses. 

It was as if it had turned from a lightning-fast arrow into an unstoppable warhammer. 

The Tyrant Mammoths' vitality magnetic fields resonated with each other, and a layer of blood-red gas that looked like smoke gushed out of their bodies. 

When the humans' artillery rammed into this red fog, it would always detonate beforehand, and at most, they would only kill the Demonic Halberd Pigs and Iron Armored Rhinoceroses that surrounded the Tyrant Mammoths, but they could not create fatal damage to these Tyrant Mammoths. 

However, that was to be expected, most of the Hell Beasts that were Grade Five and above had abilities to distort magnetic fields and form spirit energy shields. They could not be killed with just long-distance attacks.

They could only be killed by a powerful person using their weapons or fists.
