BRAM: HOT PURSUIT
Since Bram had arrived in the lower plain realm for the second time, he had been on the run and hiding for weeks now.
While he was investigating and searching for where Alex might be, he noticed that he was being followed by people from the celestial plain realm.
He considered returning to the ordain plain realm but decided against it. Bram didn't want to risk exposing his master's hiding spot to those that were following him.
That independent artificial space was very hard for his master to create and it was one of the reasons why they were able to stay in the ordain plain realm and not lose their cultivation prowess.
The people that were after Bram was sent by Amir's father. They were ordered to capture Bram if he noticed that they were after him, and from the moment that Bram found out about them, they had been quite diligent in their pursuit.
