"Sada!" The mercenary who held the shield before saw that his companion was captured by the octopus, and immediately wanted to remove the shield to pull the mercenary, but at this time, the shield was already occupied by the octopus, and found that there was a gap in the shield array, and the octopuses immediately squeezed in this direction.

Although in the next moment, the mercenary reacted to how unwise his action just now, but just when he wanted to move the shield back to its original position with hatred, he was horrified to find that because the mercenary who was responsible for clearing the octopus had been dragged out, and no one was responsible for cleaning it, he couldn't move the shield back. Several octopuses have taken advantage of this time to block their bodies into the gap they just made.

His eyes widened, but the shield mercenary could only watch as the gap between the shields grew larger and wider, and the octopuses had squeezed in and into the half-body, and several slimy tentacles were clinging to the arm on which he pulled the shield, making his movements even more difficult.

Just when he almost lost hope of stopping the octopus, the feeling of absorption from his hand suddenly disappeared. Turning his head to look at the side, it turned out that it was Nia who had finally arrived.

The lightning flashed, and in the face of these fat tentacles squeezed in, Nia did not hesitate to use the intermediate magic [Thunder Vortex]. Although the thunder and lightning elements should also be the nemesis of the octopus, the tenacity of these octopus tentacles is clearly beyond her imagination.

The power of the thunder swirl completely slammed into the tentacles, and several tentacles immediately became scorched black. However, it wasn't until Nia slashed the spear in her hand that the difficult tentacles broke off. The palm of the hand stretched forward, and the falling flower palm was pushed out, and the octopus, which had no adsorption point, was blown out by the palm wind.

"I'll block it here first, and you can go and stick it later." The fire dazzle shot out, blasting back the few octopuses that pounced on her, and Nia said to the mercenary who was still a little frightened by her side.

In fact, Nia was in the same mood at this time, once the octopus had just broken through the defense, the people exposed to the octopus attack could not hold out for too long anyway, which can be seen from the deep imprints on the shields that several shield warriors desperately resisted.

"Captain, I can hold on." Raising his arm with difficulty, the mercenary said reluctantly. Although there was no blood coming out of the place where the mercenary had been entangled by the octopus, it had become bright red and swollen, and the octopus's sucker was still firmly attached.

"Don't be pushy...... Once you've got the octopus tentacles off, remember to apply this potion. Several walls of ice rose from the front of the mercenary team, keeping the octopuses out. Taking advantage of this gap, Nia quickly took out two bottles of antidote from the system backpack and stuffed them.

Nia knew that at this time, the mercenary's arm had been punctured by the tentacles of the octopus, and if it was not treated in time, the large number of bacteria contained in the tentacles of the octopus would be enough to kill, and as for whether the antidote could be effective, she had no time to think.

In fact, under the siege of the dense octopus in front of her, Nia couldn't even get time to turn her head. It was only by relying on the ice wall skills with amazing defensive power that she could spare a little respite for herself.

From outside the ice wall came a dense rustling sound, the sound of dozens of octopuses attacking the ice wall in unison.

It lasted less than five seconds before the ice wall ran out of mana and dissipated into large swaths of ice crystals. But that didn't mean the end of the attack, and the mist became the perfect medium for Sitana to cast spells, and with the introduction of magic, the ice mist eventually rained down into the school of octopuses below.

This is the combination magic that Nia and Sitana came up with when they were practicing magic during this time, and they can reach the strength of the third order under certain conditions. And the first appearance of this magic worked very well in the actual battle.

More than thirty octopuses were enveloped in the icy rain, and as small ice rains scattered over the octopuses' bodies, a layer of ice thicker than the ice mist released by Sitana alone quickly appeared, and the ice froze the octopuses in the icy rain. Eventually, all the octopuses in this range, except for the pure black octopus that looked like an elite, all the remaining octopuses turned into ice cubes, and the octopus school opened up a large gap.

As the ice rain disappeared, the octopuses re-encircled, but relying on the buffer of this time, another shield warrior had already taken the position of the previous mercenary. This time, Nia stayed at the front of the line.

Sure enough, just as everyone expected, the black tentacle reappeared soon after. This time, the mercenaries were already on guard, and with Nia guarding in front, the tentacles never had a chance to cross the shield again.

In the end, the tentacles that could not find the target of the attack slapped heavily on the shield array in front of them, and the two mercenaries behind the shield were immediately repelled by half a step, which showed that the strength of this octopus was extremely huge.

But fortunately, after surviving the previous crisis, the mercenaries have some confidence in the rhythm of the battle, and with the combination of Nia and Starna's magic ice rain, the battle is finally on the right track.

The battle lasted for several hours, because the number of mercenaries brought by Nia was sufficient, and it was in a narrow area, although the battle became a bit time-consuming, but the battle damage was still minimized. Counting the mercenary who was pulled out by the black octopus before, only five mercenaries died in this battle, which can already be called a big victory in a battle of the same level.

Although the octopuses surrounding the front of the mercenary team were still dense, everyone was finally able to see the scene of the square in the distance through the gap in the shield. It won't be long before these difficult octopuses can be cleaned up by the mercenaries. And at this moment, the black octopus that had just attacked the mercenaries finally appeared in the eyes of the mercenaries.

"Victory! Victory! Seeing that victory was in doubt, the mercenaries shouted excitedly. At the same time, the mercenaries in charge of the attack also mustered up all their strength to attack. Soon, the only remaining octopuses outside were also wiped out, leaving the black octopus alone outside. The black octopus was even larger than the size of the exit, which was why it had not joined the other octopus attacks before.

"There's only the last one left, everyone!" After killing the last octopus at the exit passage, the red-eyed mercenaries immediately set their sights on the black octopus outside the exit. Shouter, the mercenaries rushed forward.

Seeing that many mercenaries were surrounding him, the black octopus did not use its tentacles to attack this time. Instead, he used his four tentacles to support the ground, and his whole body stood up a little comically.

"Attention, everyone, this is the skill of the black octopus."

Seeing this, none of the mercenaries felt funny, because they all knew that this unusual movement was often a precursor to some magical beasts activating their skills.

The ranged mercenaries began to retreat, the melee mercenaries protected their bodies, and the black octopus in the middle began to spin rapidly.
