Chapter 746: Betrayal

The Four Generals were under the Lord of the Upper Realm. However, because Aliac didn't involve himself in the matters of the Upper Realm, each of the Four Generals handled matters related to the Upper World. 

Essentially, the four Generals held positions akin to rulers of the Northern, Southern, Eastern, and Western worlds within the Upper Realm.

Moreover, all four of them had a bad relationship with Karyk. In the past, when Karyk was killing people to collect enough life essence to bring his sister back to life, the Four Generals had gotten involved. 

They tried everything to kill Karyk. Unfortunately, Karyk wasn't caught. After gathering the life essence he needed, Karyk left the Upper World and returned to the Lower World.
