The Goblin Great Swordsman died, clutched by numerous resentments. At that moment, Yi Zheng approached and scooped up the Resentment Crystals floating off the Goblin Great Swordsman's body into his pouch.
Resentment +500!
However, Yi Zheng wasn't pleased because he had just tried and failed; no matter what he did, the lesser monsters didn't produce any resentment.
It seemed that only human players and the bosses among wild monsters could produce negative energy.
This irked him a bit, as it seriously delayed his skill upgrade progress!
"To upgrade, I can only kill players, and to get skills, I have to kill BOSSes—won't let me have the best of both worlds!" Yi Zheng felt somewhat frustrated.
Then he gestured at the Goblin Great Swordsman, "Evil Extraction!"
Three skill pearls flew out from the Goblin Great Swordsman, one shimmering with a faint glow, the other with a slightly stronger light.
