According to Minos' decision, he used his black hole to swallow all the cryogenic urns in the alien military facility, forming a black hole capable of threatening even the existence of level 96 beings.
By storing such a region of space in a high-level grade-4 array he had previously purchased on the Divine Continent, Minos had secured the mass destruction weapon he intended to use to lead his people out of the North Sea.
However, he kept his plans a secret from most of his crew after explaining the situation they were in to the rest of the group and asking for everyone's cooperation in understanding the technologies left behind by the enemies.
But even without giving the rest of his crew all the details, Minos didn't keep everything from all. He told them he had one last alternative to try to leave this area in a few years and that he was even willing to use his supreme weapon if necessary.
