The short creature was unable to disguise the excitement in its eyes. Each time he took control of the Daoguard Tower and used it to deal with powerful figures, he felt extremely happy.
This was because if he truly engaged in a 'fair fight' against those powerful cultivators, he would probably be annihilated with ease. But with the Daoguard Tower at his disposal, he was able to toy with them instead! By now, this was the only bright spot in his life, the reason for him to keep living. The Sithe had been defeated, after all, and his master's orders meant he had to stay here forever. His life was one of solitude and despair. If he didn't have the occasional bit of entertainment, how could he have possibly been able to stay alive? His Dao-heart probably would've crumbled long ago, resulting in suicide.
