Although his own strength was only at Tier 4 Seven Stars, far from being a match for a Tier 5 Powerhouse, as a battle-hardened Kingdom General, Ulis had more than once confronted Tier 5 Powerhouses from other countries when leading his troops in battle.
Therefore, Ulis clearly understood that although a Tier 5 Powerhouse was extremely powerful, as long as the overall combat power was not inferior to their opponent, everything was still uncertain.
He had enough experience to hide himself, avoiding the detection of the enemy, and even if he exposed his flaws and location to the enemy, he had adequate countermeasures to escape from a Tier 5 Powerhouse.
Moreover, among the five legions he and Yarvi led, two were secretly formed and trained according to the standards of the Royal Army Corps. Although their combat power was not as strong as the real Royal Army Corps, they were still superior to ordinary noble legions.
