Since the airplane assassination attempt by the Lieutenant Colonel, Yan Fei had once again entered the mode of staying at Dream Island. During this time, he never went out, and despite being a God-Level Expert with self-defense capabilities, he was not invincible. Therefore, for safety reasons, he firmly refused to leave his Lair, keeping himself out of harm's way.
Dream Island was Yan Fei's territory, boasting island-wide monitors under the surveillance of the Artificial Intelligence "Dream." There were no secrets from Yan Fei on Dream Island. Thus, Yan Fei had no need to worry about being ambushed here, as his safety was absolute.
