Understanding the situation, Peter Brown thought that regardless of whether it was true or false, one of his tasks was to gather intelligence, and if he transmitted the intelligence back, he would have completed his task.
With this in mind, Peter quickly returned to his room and used the communication formation to send the information back. Not only that, he also indicated that in obtaining this intelligence, he had been discovered and was escaping towards the heart of the Grand Artifact Sect.
After completing these actions, Peter destroyed the communication formation, making it appear as though he was fleeing for his life.
