After returning to the surface of Dream Island, the first thing Yan Fei did was to enhance its defenses. He summoned a large squad of two hundred fully armed Guard Squad members to establish a solid defensive fortress here. Yan Fei also planned to upgrade the security of this passage, deploying the powerful weapons invented by Yang Qi's laboratory inside, considering it as the last line of defense to protect the secret of Cave Heaven Paradise.
Yan Fei would also use the Artificial Intelligence "Dream" to strengthen surveillance here, absolutely forbidding unauthorized personnel from entering. Even if suspicious individuals were found loitering nearby, they would be immediately expelled by the Guard Squad members.
