Lucifer's plan was simple yet cunning. He didn't want to kill Shark; instead, he aimed to alter Shark's perception of him. By doing so, he hoped to recruit Shark to his team. Simultaneously, Lucifer intended to divert the Blue Emperor's attention to someone else, thereby removing himself from the emperor's scrutiny. To achieve this, he disseminated false information suggesting that Shark was the heir and harbored unfavorable views towards the Blue Empire. This deception provoked the Blue Emperor into taking drastic measures against Shark, including sending assassins.
