The Halo system of psychic techniques originated with the Empire's Starrealm Knights. It was a system of psychic arts that could be learned and passed down. To be fair, it was indeed a major occult achievement the Empire had left to the civilizations of this era.
It was clear that although King Vellent claimed he wasn't skilled in military affairs, his mastery of halos was still quite impressive. Even Yu Lian, a Saint, felt his spirit strengthened considerably, and couldn't help feeling more fired up than usual. If even he felt that way, one could imagine what state the ordinary soldiers would be in.
He guessed this was some kind of large-scale fighting-spirit halo. It wasn't particularly difficult to use. Any Starrealm Knight who had served as a junior or mid-level officer should be able to master this combat art. Even a pure "meat shield" like Bloodroad probably wouldn't be an exception. The real difficulty lay in its range.
Judging by what he could see, both its height and breadth were certainly worthy of a perfect score.
The Imperial soldiers had clearly been ready for this for some time. Before King Vellent, holding aloft his golden greatsword, let out his rousing cry, they had already prepared to charge.
Of course, although the soldiers affected by the fighting-spirit halo displayed courage on par with robots, they had also retained the combat skills expected of elite armored grenadiers. The fireteams at the front drove their specialized armor suits through the toppled gate, protected by automated support platforms.
The energy autocannons mounted on their specialized mechs roared to life at once, a dense rain of energy rounds blanketing every vaguely visible enemy in a storm of fire. Then the grenadiers, already wielding their shock hammers and crystal axes, charged inside with a shout.
