Rushing out were not only those 100 mutated hippos, but also 50 mutated elephants and rhinos trailing behind them.
These 200 massive elite animals directly formed a thick barrier on the periphery of the original formation.
More importantly, this "barrier" was not only capable of defense, but also possessed super-strong offensive power.
The mutated elephants extended their long trunks and easily crushed the piranhas to death with the support of nearly 300 tons of force.
As for the mutated rhinos, their specialty was ramming, but this mode of attack was of little use against smaller targets.
However, dealing with Fourth Order mutated beings didn't need to be so troublesome; a stomp with 300 tons of force was enough to crush anything to death.
Of course, while their attack was fierce, they were not the true main force.
The real main force hunting these piranhas were the mutated tigers, lions, and cheetahs.
