Minos was right in thinking that Henricus Longus' goal was to make him use his powers to create a super-powerful army based on his techniques.
Immediately after he put the Spatial Sword aside, he looked at the Infinite Dream. He could now use this technique to affect 16 people who were 100% stronger than him, a 100% improvement over the previous phase of this technique.
This number of people might not seem like much, but it was just an illusion caused by the number. With this technique, he could now defeat 16 people who were 100% stronger than him with a single glance, who could be level 94 or 95 Demigods if he used his innate ability in conjunction with this technique.
His Dragon's Gaze was superior to this mental technique, so since it had also evolved, Minos felt that it could even affect level 96 Demigods!
Considering how different the levels of the 10th stage were, he still didn't feel he could affect high-level Demigods.
