The bay’s entrance was very narrow, Jiang Cheng estimated, about only a few meters wide, and he also noticed several mermaids guarding there.

Jiang Cheng knew what they were doing.

Because the entrance was so narrow, the Sea Wolves, despite having a numerical advantage, could not swarm in during the attack. In this way, the mermaids would have an easier time dealing with them.

Jiang Cheng had seen the attack method the mermaids displayed to them earlier, the sound waves they emitted had considerable offensive capability.

Yanran and Ba Lv were both people with considerable abilities, those sound waves could affect them, so for those Sea Wolves, the mermaids’ attacks would be even more unbearable.

However, as time passed, the Sea Wolves’ resistance to the sound waves grew stronger, and the mermaids’ sound waves didn’t possess lethal effect, so they were now at a disadvantage.

Jiang Cheng guessed that if the few mermaids in front of him emitted sound waves together, perhaps those Sea Wolves wouldn’t be able to withstand it. Otherwise, their bay would have long been invaded by the Sea Wolves.

"Teacher, do you think we have no good way to help them?" Yanran couldn’t help but ask when she saw Jiang Cheng not speaking, "Those mermaids are really pitiful."

Jiang Cheng didn’t directly answer Yanran’s question. He turned around and said to Yanran and Ba Lvluo, "Come, let’s analyze, where is the problem."

"It’s very simple, the problem is that we can’t gather these Sea Wolves together to wipe them out in one fell swoop," Ba Lvluo answered.

"Although we can use mermaids as bait to lure the Sea Wolves, from our observations on the road just now, once they sense something’s wrong, those Sea Wolves would flee quickly, as Yanran added.

"Yes, that’s exactly the problem," Jiang Cheng nodded.

Yanran and Ba Lv noticed Jiang Cheng’s expression, and they almost simultaneously asked, "So is there nothing else we can do?

Jiang Cheng nodded and was about to answer when those Sea Wolves attacked the bay inhabited by the mermaids.

Sure enough, as Jiang Cheng had imagined, the narrow entrance allowed the Sea Wolves, despite their numerical advantage, to attack the guarding mermaids slowly, one by one.

And those guarding mermaids, their sound waves were their only means of counterattack.

The sound waves emitted by one mermaid were hard for even Yanran to withstand, so when several mermaids emitted sound waves together, they would surely be much stronger.

Plus, the narrow entrance amplified the effect. In this confined space, the sound waves emitted by the mermaids would not dissipate, thus strengthening them significantly.

Based on Jiang Cheng’s hints, Yanran and Ba Lv also noticed these subtle details. At this point, they finally understood why, even when the mermaids’ sound waves gradually lost their effect on the Sea Wolves, they could still survive.

The mermaids chose this bay as their habitat and their last fortress. One must say, they had good insight.

In this battle between mermaids and Sea Wolves, Jiang Cheng and Yanran did not participate. They merely stood by and observed, hoping to gain some insight from this fight.

The attacks seemed to have happened more than once or twice already.

As the Sea Wolves attacked, a mermaid emitted a signal, and one by one, mermaids swam out from the depths of the bay, without any hint of panic.

Those mermaids automatically formed a line, waiting there quietly.

The narrow entrance of the bay was fully utilized by the mermaids, although Jiang Cheng was unsure whether they chose this spot intentionally or accidentally, he wanted to ask the mermaids later.

Three mermaids formed a group and stayed inside the entrance, as the water was not deep and the water quality was crystal clear, so every move of the Sea Wolves was visible to Jiang Cheng and the others.

Jiang Cheng pointed out to Yanran and Ba Lv because the water was so shallow, it prevented the Sea Wolves from diving below to launch a sneak attack.

Yanran and Ba Lv nodded continuously, simultaneously sighing, feeling that this bay was truly a sanctuary for the mermaids.

If it weren’t for this unique terrain, the mermaids would probably have long become food for the Sea Wolves.

And with the unique terrain combined with the mermaids’ unique attack method, it indeed rendered the Sea Wolves useless despite their numerical advantage and ferocious attack power, leaving them to sigh at the sight of the mermaids.

Facing the situation where only two could enter the narrow entrance at a time, as the Sea Wolves were about to approach, the three mermaids guarding the entrance emitted sound waves.

Sure enough, when three mermaids attacked like this simultaneously, the effect was vastly different. The sharp and piercing shriek caused the foremost Sea Wolves extreme pain, making them thrash in the water, howling incessantly, flapping their broad tails against the water, causing a chaotic mess.

Yanran and Ba Lv couldn’t believe how the mermaids’ sweet, charming voices could emit such a dreadful noise.

To describe it, it was like the sound of a sharp object being dragged forcefully across metal, a sound that could directly penetrate one’s mind. Even if you covered your ears, you still felt uncomfortable and on the verge of madness.

The Sea Wolves succumbed to the attack of the mermaids, and the foremost Sea Wolf started to flee, with one even biting the companion blocking its way.

The front Sea Wolves retreated under the mermaids’ counterattack, while the ones behind continued to advance.

And those counterattacking mermaids, when they felt a lack of energy, another group of mermaids would promptly replace them to continue resisting the Sea Wolves’ advance.

Their movements were unhurried and orderly, clearly demonstrating that they were very familiar with this way of fighting.

Jiang Cheng and the others, as observers, watched the confrontation between the mermaids and the Sea Wolves.

Thanks to the advantageous terrain, even though the mermaids were in a passive and defensive position, they were still able to fend off the Sea Wolves’ attacks, but that was about it.

If this continues long-term, they would always find themselves in a passive defensive position when facing the Sea Wolves.

The problem had already revealed itself, which was that the mermaids’ sound wave counterattack lacked lethality. The sound waves they emitted could only drive the Sea Wolves away, and as the wolves’ resistance grew stronger, their attacks would gradually lose effectiveness. Thus, over time, they would inevitable face extinction.

The Sea Wolves’ assault showed no signs of abating, continuing to rehearse their unique attack strategy.

This monotonous and tiresome battle made even the usually passionate Yanran unwilling to watch, feeling that it was wasting their precious time.

Then she whistled, and the Flaming Firebird, lying impatiently beside her, flapped its wings and swiftly soared into the air.

Next, it folded its wings in the sky, plummeting like a meteor, diving straight down towards the battlefield below.
