The mermaid asked her teammates to start the counterattack and stopped being passive.
They could be passive before, but after that monster came, they had to fight back.
The corrosive liquid attack was just too lethal!
After the mermaid told the group to target the corrosive monster, the sonic guy immediately changed his target and used his sonic attack to hit the body of the pitch-black monster with some strange liquid dripping out of its skin.
Many other monsters created a 'vacuum zone' a few meters around this monster simply because the other monsters didn't want the strange monster to corrode them to death with that vicious black liquid from the skin of the monster.
The sonic guy's attack was not quite visible but the surrounding water rippled before hitting the targeted monster with a burst.
There was some kind of small 'explosion' in the water and the corrosive monster was surely hit by the sound wave attack.
However, after the waves and the turbid water cleared up, everyone, who was already a distance away from the corrosive monster, saw something that they could not believe with their own eyes.
The corrosive monster that looked like a strange fish trenches in a vicious black liquid still swung the tail energetically, coming out of the murky water with great vigor.
It was as if the previous sound wave had no impact on it at all!
The contestants all looked at the strange fish with eyes full of horror.
Even though monsters had tough skin, it was impossible not to be wounded even the slightest.
Even the previous two monsters with thick skin also suffered some superficial scratches and wounds, which was why they bled and then their blood attracted many other monsters.
It was near impossible for monsters not to suffer any injury from the sonic wave attack unless they had some kind of barrier ability!
"Is this for real?! Don't tell me this monster has some kind of barrier ability made from its corrosive liquid on the skin?"
The sonic guy shook his head in horror while the others also looked at the tough monster with wary eyes.
It was a bad thing if a monster had a barrier ability while having an offensive ability at the same time.
They could not quickly kill the dangerous monster but the monster could still attack them freely.
The audience also saw the strange monster different from other monsters and they also held their breath nervously for the contestants.
[The contestants are too unlucky to meet such a monster, right? I've seen a lot of corrosive monsters but have never seen one underwater.]
The underwater was different from the land and a corrosive monster underwater could be way more annoying and dangerous than the corrosive monsters on the land.
The corrosive monsters underwater could pollute the water.
If there was no barrier, the five contestants would all be contaminated by the corrosive water and they would all die.
The surrounding monster was also careful not to get too close to this monster or swim in the polluted water.
Even some monsters directly gave up on pursuing the five contestants just to avoid the polluted water.
The contestants felt that if the corrosive water touched their barrier, sooner or later, their barrier would also be corroded bit by bit and they would have to fix the barrier again aside from guarding against the direct corrosive attack from the monster.
"Is there no way to quickly kill that monster? If it has a barrier ability or the corrosive liquid has some kind of barrier element, won't it be a dead end?"
The sonic guy scratched his hair irritably as he asked the mermaid and the glasses man who was taking turns controlling the water barrier with the mermaid.
The mermaid and the glasses man looked at each other and sighed.
"We can manipulate the polluted water to never touch our barrier and use this against the other monsters, but we still have no idea how to defeat that corrosive monster."
The mermaid was indeed smart and quickly thought of a strategy, but in the end, there were many limitations when fighting underwater.
The mermaid actually didn't have such restrictions but the fake mermaids and mermen around her were all vulnerable in the water.
Even if they had fishtails and could breathe underwater, it didn't mean these people could be as free as the real Merfolk race members when fighting underwater.
"For now, let's solve the other monsters first and fix the barrier if it was corroded. Since we can't deal with the corrosive monster so quickly, we better focus on others for the time being."
The others obeyed the mermaid's suggestion and while the mermaid controlled their water barrier to carry all of them away from the flock of monsters behind...
The glasses man used his water manipulation ability to control the polluted water around the corrosive monster and immediately threw the polluted water into the flock of other monsters.
Those monsters saw the sizzling black water and they all instantly fled to all directions, avoiding the polluted water.
However, the size of these monsters was huge, and it was difficult for some monsters to run away so quickly, unlike the more agile monsters in the crowd.
Thus, one or two huge monsters were hit by the polluted water and their tough skin could withstand the water pressure, plus many harsh environments instantly melted bit by bit.
"ROAAAAR!"
The injured monsters roared in pain as they wriggled around. Their skin was slowly devoured by the vicious polluted water and soon, their flesh and bones were exposed.
All of this happened in just a blink of an eye, so fast that the contestants were in disbelief.
