Li Yuanqing's current strength is at the sixth-grade Grotto-Heaven Realm. He also actively signed in every day and obtained many treasures. There were also many cultivation techniques that required actual combat to increase one's proficiency. However, he did not have any opponents in the Northern Kingdom.
Even the strongest, Zhaoyang and Wang Xian, could not be considered his underlings compared to him.
An expert was lonely!
Where could he find a sparring partner? It was naturally these demons who had escaped from the catacombs. They were powerful and he wasn't afraid of killing them easily. Most importantly, with these demons around, Li Yuanqing could easily sign in at the entrance of the catacombs.
These demons were equivalent to giving him benefits and treasures. To Li Yuanqing, the more the better.
Therefore, when Li Yuanqing saw that the stone wall was filled with demons, he looked left and right and chose the most energetic and fierce demon.
