Chapter 209: Upgrade, Hell Skeleton King!
[Ding~ Congratulations! During the process of killing [Vengeful Spirits], you have triggered [Necromancer's Harvest]. Do you wish to harvest the Vengeful Spirit as a pet?]
It's not that the ghost was particularly powerful.
But if Zhang Yue harvested this ordinary-level ghost, he would finally have enough to fuse and upgrade his tenth rare-level pet.
The increasingly sidelined and almost forgotten Dark Skeleton King was finally about to undergo an upgrade.
Thus, using ten rare-level pets as fodder, Zhang Yue fed them to the Skeleton King.
[Ding~ Congratulations! Your pet [Dark Skeleton King] (Rare) has been upgraded to [Hell Skeleton King] (Epic). The levels of its unique effects have been enhanced, and it has gained a new unique effect: [Rebirth]]
Looking at the Hell Skeleton King before him, which had grown taller and exuded a more imposing aura, Zhang Yue sighed, "You've made your presence known again, Skull Bro."
After the quality upgrade, the Skeleton King's basic attributes experienced a significant boost.
As a warrior-type pet, the Hell Skeleton King pursued a comprehensive development of strength, intelligence, endurance, aesthetics, and labor.
