267 Artificial Secret Realm

Inside a mystic cave.

Lu Wu stared in disbelief at the thousands of Earth Rats hurling towards him.

"Damn it, how is this possible!"

Lu Wu was not an ordinary Summoner.

In addition to being a Professional Summoner, he was also a Master Cultivation Master, the man who was destined to become a Grandmaster.

Lu Wu's knowledge reserve in the field of Summoned Beasts was far beyond what an average person could imagine.

His understanding of Earth Rats went beyond the information on their attribute panel; he had even more details mastered from various texts.

"As far as I know, although Earth Rats live in groups, it's usually just a couple with a bunch of babies, and the young leave to start their own families once they mature. At most, there might be seven or eight gathered together, so how could there be such a large number of them? And they're so aggressive too, daring to attack 'Little Skeleton' who is at Leader Level despite being mere Boss Level.
