The hill was the perfect bait, and the spreading gory marsh increased its range, attracting more distant packs that fell under Khan's claws.
The additional corpses enlarged the marsh, its scent reaching packs even further away, attracting more battles and starting a new killing cycle. Khan could continue the conquest without moving from the mineral, but the task barely occupied a fraction of his mind.
As fearsome and relentless as the monsters were, Khan simply couldn't consider them a threat. He kept training, focusing on increasing his attunement with mana in that natural environment while his runes dealt with most incoming enemies. Occasionally, Khan had to stand up and finish off a few survivors, but the process never took longer than a minute.
