To be honest, the violent rats weren't very strong. As long as they wore armor or cast a Wizard armor spell, with the power of the violent rats 'attacks, they would only have a 50 - 50 chance of actually hitting Zhao Xu.
not to mention, the star cloak on zhao xu's body was enough to make him immune to the bite attacks of the berserk rats.
Unless it was a race that was born with a weapon that could be considered a magical weapon, the cloak that Zhao Xu was wearing made him immune to normal weapons, which was equivalent to making him immune to the monsters 'natural weapons.
Naturally, they wouldn't be able to do anything to Zhao Xu.
This was the power of the seventh-level spell, starry cloak.
This was also the reason why Zhao Xu dared to walk in front of them without any fear.
zhao xu observed the berserk rat that was almost a meter long and looked extremely large to the outside.
