Although the boss was clearing attacking with all it has, it would never stop the party from attacking him on and on until it reaches 20%.
It was time for the killing strike!
As mentioned before, like Zhang Yang and Wei Yan Er who possess {Killing Cleave}, other classes had the skill that could increase damage, once the target has lower or equal to 20% HP. When the conditions are met, the skill can be activated to increase one's power. As such, the party had activated their "killing" skills. Wei Yan Er took a bottle of [Amateur Power Potion Transmuted Grade 10] and unleashed {Indiscriminate}. She rushed over to the boss and consumed all her Rage to cast {Killing Cleave} on the boss.
'-3,226,163!'
The damage that she had dealt that instant was so powerful that even Zhang Yang had to stop and praised the girl.
"Good job!"
