Apocalypse befell, and roommates performed a skyward ritual. As the fog descended, the Book of Blood Spirit appeared in the hands of all survivors, and only those with a Contract monster could survive. Su Han directed his gaze to the neighbor who had already mutated and twisted, silently pulling out a gleaming fruit knife... Grotesque meat corpses, giant spiders with gaping mouths, eyeballs enveloping the city, one-eyed sharp-toothed hand monsters... Civilization fell, cities shattered, and all humans became meat for the monsters. There was only one way to survive: Use monsters to fight monsters.

Although only two skills were enhanced after the advancement, the amplification was still exhilarating for Su Han.
A LV3 Parasitic Corpse Willow, after advancement, saw its numbers leap to 10,000. Among its kin, the number of Second Order individuals increased significantly, and their strength could reach Second-order Intermediate level. The distance they could traverse doubled at least, stretching to 80 kilometers.
This distance meant that not only could they be planted within the city districts, but also beyond them—many areas could become the Parasitic Corpse Willow's territory. This was especially important for Su Han's subsequent exploration outside South City, as it would also become the first line of defense on the outskirts of the city.
The walls could not expand indefinitely, but the Parasitic Corpse Willow could—the more, the better, and the farther, the better.
All monsters that wanted to approach South City would have to pass through them first.
