Immediately afterwards, they lined up and began to mutter in a low voice, as if condensing some special power.

If Lu Jun is here, you will find that the people in black robes are casting combined abilities. This ability is very difficult and requires multiple people to use it at the same time. As long as one person makes a mistake, the ability will fail.

But as long as it is successfully used, the power of this ability will reach the level of Tier 4 ability.

If the number of people gathered at the same time is a little more, the overall power may reach the effect of the fifth-order ability.

Thirty seconds later, the originally bright sky suddenly darkened and was covered by a large circle of dark clouds, above which there was still a gleam of lightning.

Seeing the change in the sky, the naga also noticed something was wrong, and all the female naga immediately used their brain power to prop up an icy sky, preparing to block the possible attack in the future.

As the "boom boom..." thunder continued to sound, hundreds of sky thunder suddenly fell from the top of the dark clouds, directly blasting on the ice shield supported by the female naga.

The light from the sky thunder made the entire ground tremble, and the violent thunder element swam through the air, causing the hair on everyone to stand up.

In front of this kind of attack, the ice shield did not hold up for two seconds, and it shattered at once. The female Naga hiding under the ice shield was also severely injured as a result, and she couldn't help shivering.

Although the male naga's body is extremely strong, they are sea creatures after all and are not resistant to electricity. Once struck by lightning, there is basically no possibility of survival.

Seeing that the number of naga that fell under the sky thunder reached thousands, and the sky thunder was not over yet, the person in charge of the battle on the naga side could no longer stand, and immediately ordered to retreat.

Although they managed to land ashore with difficulty and the mission was not completed, the damage left on the shore was too great, and they had to avoid this attack first.

Upon hearing the order, neither the male nor the female naga hesitated, gave up the attack, dropped the corpse of his companion, jumped off the coast, and swam into the sea.

Seeing this, the black-robed people who created the dark clouds above all expressed joy, as if they wanted the naga to enter the sea, continue to output their brainpower, and control the dark clouds above to move to the sea.

Seeing the dark clouds following them closely, the naga were very upset, swimming faster, and at the same time ordered more electric eels to come up.

When the first sky thunder bombarded the sea, the naga in this area only felt their bodies numb, the snake's tail could not move, and the lungs could hardly breathe.

Fortunately, this feeling was only for a moment. The electricity of the sky thunder was quickly absorbed by the electric eels, allowing the naga to continue swimming.

But as the black clouds covered more and more sea areas, when the sky thunder continued to fall, the electric eels could no longer bear it, and they exploded and died, turning their ruptured stomachs on the sea.

This is because the power of the sky thunder is too great, and the number is so large that even if the electric eels can absorb the extra electricity, they can't hold it, and the explosion is inevitable.

Without the help of the electric eel, the naga were in misfortune, and there were constantly naga falling onto the sea due to paralysis, being electrocuted alive...

In this way, the dark clouds in the sky lasted for two minutes, during which nearly a thousand sky thunder fell.

When the sky thunder is over, there are no naga standing in the sea, only the corpse of the naga and the corpse of the electric eel.

The dark clouds that originally covered this place slowly dissipated, revealing the sun and blue sky in the sky, as if nothing happened just now.

But the corpses on the sea are enough to explain everything. A small part of these naga was directly hit by the sky thunder, leading to cardiac arrest and death.

More importantly, the seawater conducts electricity, allowing them to be passed through the central nervous system by current, causing serious disorders of the central nervous system and death.

This also means that almost all of the tens of thousands of naga attacking the black-robed men died, and the offensive mission was completely failed, leaving only a large number of corpses and blood-filled waters.

As for the Naga who escaped by chance or was not completely electrocuted, it is estimated that both hands can be counted, let alone continue to attack.

Seeing their defensive victory, the black-robed men were not too excited, because fighting of this level has often occurred in recent days and they have become accustomed.

And they also knew that some sea creatures would come to clean up Naga's body in a short time, and the sea surface would be clean again.

Those in black robes who had just used the combined abilities together collapsed on the ground, taking time to rest.

After all, using this kind of ability will consume their mental and physical strength very much, almost "squeezing them dry"...

"Master Hongyue, the monsters have already been repelled, can we restart our Haijing Extractor?" A man wrapped in a black robe half-kneeled in front of a person in a red robe.

This male black-robed man is the ability who just grabbed the source of the power grid and sent electricity to attack the Naga. His strength was Tier 3.

Even a Tier 3 ability person would kneel down in front of the red robe man, which shows that this red robe man has a very noble status in the Ba Buzhong.

"Well, restart it, and send someone to keep watching the sea." The person called Hongyue spoke, and she could be heard from her voice as a female.

"Yes, Lord Hongyue." The black-robed man said respectfully, but he didn't get up and leave immediately, but continued with some hesitation, "I have another question below. I wonder if Lord Hongyue can answer..."

Seeing the black robe man harp, Hongyue was obviously a little impatient: "Say something!"

Hearing Hongyue's stern voice, the black-robed man couldn't help trembling: "That's it, Lord Hongyue, we have been here for four days, and the Haijing extraction instrument has been working for three days."

"But in these three days, except for some rubbish, we didn't get a single sea crystal. Have we got the position wrong? Do you want to change the position?"

After speaking, the black-robed man pointed to the foul-smelling "garbage mountain" in the distance. There were some plastic, some silt, and some small sea creatures that had been dead for several days, but they didn’t have the sea crystals they needed. .

And the thing on this "garbage mountain" is the cylindrical sea crystal extractor that was shipped these days, and it was useless at all, no wonder the people in the black robe would question it.

"Oh? Do you think there is a problem with the location provided by the organization? Or do you think there is a problem with the Haijing extractor provided by the organization? Would you like to point me to a location?" Hongyue didn't even look at the "garbage mountain", just Quietly staring at the black robe humane.

"I dare not! Lord Hongyue misunderstood! I just hope to find Haijing for the organization as soon as possible! Don't dare to question the organization!" The black-robed man suddenly brought his forehead to the ground and said in the lowest voice.
