Yes, like the Ancient City Clan, he was also of the Kobold race, but his Kobolds were different from the others.
Firstly, just by eyeing their size, they were definitely taller and stronger than ordinary Kobolds, and he had more of them than Lin Xiao had ever seen amongst his contemporaries—up to thirty thousand Kobolds. It was uncertain if he still had any in reserve within his Divine Realm, not participating in the battle.
Yet, this wasn't the reason everyone had their worldview shaken. After all, a Kobold is still a Kobold, no matter how much stronger it may become through mutations; as long as it doesn't ascend in rank, it's not considered powerful.
What truly made everyone doubt their lives was the presence of a formation of Kobold Dragon Vein Magicians amidst the Kobold army.
Yes, not a few isolated individuals, but an actual formation—estimates put it at a minimum of over two hundred.
