Abigail and the others primarily focused on absorbing and purifying the corpse poison in densely populated cities.
In other areas, after the zombies were cleared out, the corpse poison in the air would gradually dissipate over time, though the process was somewhat lengthy.
Meanwhile, relying solely on absorbing the corpse poison from the air did not significantly enhance Abigail and the others' growth, so Elijah provided them with some of the corpse poison stored in the treasure vase talisman for their cultivation.
After establishing his foundation, Elijah's mastery of the Thousand Silken Souls Technique improved to a new level, making him no longer concerned about Abigail and the others surpassing his strength.
After dealing with the zombies in the country, Elijah began his overseas journey.
He was less meticulous in dealing with foreign zombies, targeting only the densely populated cities.
