Although his Personal Guard Team of a hundred members was now entirely composed of Superhumans and everyone on the ship obeyed his commands, he was acutely aware that those people were only superficially attached to him, harboring their little thoughts and calculations within their hearts.
However, he had once controlled the laboratory that produced the Awakened Potion. Anyone who wanted to awaken a Super Ability had to curry his favor to obtain the potion. But once all the equipment used for producing the potion was lost...
...then the group that stole the equipment would certainly take action against him without any hesitation once they accumulated enough Superhumans.
The Captain was so angry precisely because he needed to ensure that his current status remained unaffected, hence why he dispatched half of the Personal Guard Team to search for the missing equipment and had even granted them the authority to execute first and report afterward.
