"Insidious Attack" 

Although the slime was hard to fight, the boys believed that if their attacks were a bit stronger and directly hit the monster core...this slime would die!

The trios immediately took out various potions to boost their attack's strength and energy, directly pushing their attack value to the top. 

It was enough to kill this slime with one hit. 

However, before they could do so, the trios dodged the latest batch of cannon balls, as usual, letting the balls hit the barrier and melt the arena barrier's behind them. 

It was just that....they would never expect there was a fake ball among the real cannonballs. 

When the balls rushed to hit the barrier, one of the blood cannonballs actually shot straight at Felicia! 

And this slime also carried its mother's corrosive skill. 

While rushing toward Felicia, it simultaneously shot smaller cannonballs with lower lethality but enough to melt the skin and some flesh.
