They made sure to gather as much energy as they could for that night, knowing that they finally had a direction. Using the previous strategy of studying the core and carcass composition, they slowly headed in the direction where more anomalies were happening.
The following day, they passed a few more kilometers deeper into the Undead Zone, to the point that their original entry point was already well beyond the horizon.
With increasing proficiency, they killed another large batch of Undead. These were once humanoid creatures, but now they were non-sentient monsters. They saw this as mercy killing.
Although they already had a lead, there was still plenty of trial and error involved. They were trying various directions, after all, and sometimes the 'samples' didn't show change or had lesser changes. This meant that they were heading farther away from their target direction.
Every step was one kilometer, and the energy taken by creating platforms each time was no joke.
