Whetstone: A good whetstone, while sharpening your sword, it will also make your body harder!
Every time you experience a qualifying battle of the same level, your endurance will increase by 1 point.
This was the new passive skill's description. It could be said that this passive was very strong.
Most of the other passive skills that Zhou Feng had previously obtained were decent, but this was a passive skill that directly increased his attributes and could be stacked indefinitely.
"Endurance? This seems pretty good! In a battle of the same level, it means that I can bully someone in the same realm!"
Zhou Feng analyzed it carefully.
The existence of the passive Whetstone made the cost-effectiveness ratio of a battle very high.
And because of the Soul Harvesting's existence, this passive skill could also be triggered during a battle.
In other words, he needed to find people to fight constantly!?
