Two days had passed since Adam's battle against Anelez and Erada. During that time, the Path Construct had absorbed almost all of the energy of the Dark Heart, but it still needed a little more time.
Adam didn't mind staying in Izardo for a while longer. He knew he would have to return home to the Citadel via a difficult route. It was unclear what would happen during this period, as he couldn't simply teleport or summon a fighter jet to take him away.
The Tarnished Lands and Izardo were too deep in the monster lands. Here, Adam had to follow the same rules as every other monster.
Sure, monsters also had ways to move quickly, but they weren't available to a K4-Phantom.
The Renegades, the monsters at Izardo, and many others were neutral towards the Phantoms, but that didn't mean they were friends or allies. Moreover, many monsters feared Adam. They understood that he was their enemy and didn't know what he would decide to do next.
