At the peak, tens of thousands of captives ate and drank Lazar, which would certainly produce a large amount of waste and wastewater, which was discharged directly into the ice sea through drainage channels located below the sea surface.

The diameter of each drain pipe is more than half a meter, and an adult can easily get into it, because of this, Youquan Ancestor has set up a dense crystal wire mesh on the mouth of the drain pipe, surrounded by defensive talisman arrays, which can pass super arc and extremely cold qi to the crystal wire net.

Forcibly destroying the crystal wire mesh will definitely be perceived by the guards above.

The opening of the crystal wire mesh was too narrow, and Li Yao was not sure that he could control the Thunder Dragon, so he got into it unconsciously.

However, this did not bother him.

He drove the Thunder Dragon deeper and deeper, came to a position of six or seven hundred meters under the sea, waited quietly in a trench for a while, and sure enough, he found a moray eel more than half a foot long and crystal clear all around.

This light blue monster beast with no eyes and almost no distinction between head and tail is called the "Devil's Head Ice Eel", and it is one of the very few monsters that can survive in the Arctic ice sea.

Originally, they would not have inhabited near the Yinfeng Islands so north, but Li Yao estimated that it was the large amount of wastewater and garbage discharged from the "Youfu" that carried certain nutrients that attracted these ghost-headed ice eels to come here without fear of severe cold and whirlpools.

Generally speaking, the devil's head ice eel prefers to live in dark places where it is 300 to 800 meters underwater.

However, when hungry, they will also venture up to a hundred meters or so to find food.

In particular, the drain outlets, which are rich in a lot of garbage, are their favorite.

Devil-headed ice eels often burrow into drains, accidentally touch crystal wire mesh, and are killed by arcs and frost.

Li Yao also found half of the bones of a ghost-headed ice eel at the mouth of a drainage channel during his survey yesterday. After thinking about it carefully, I figured out this truth.

"Whoosh!"

When the ghost-headed ice eel opened its round mouthparts and devoured the gravel of the seabed with its mouth, sucking nutrients from it, the Thunder turned into a streamer of light and pierced deep into its mouth!

Devil's head ice eel. Jumping suddenly, he was instantly killed by the Thunder.

The Thunder burrowed into the mouth of the Devil's Head Ice Eel, using it as its best disguise, and swam towards the drain.

When he got close to the crystal wire net, Li Yao didn't dodge at all, and swaggered head-on!

"Snort!"

On the crystal wire net, a burst of dark blue arc erupted in an instant, electrifying the ghost-headed ice eel to a straight and crystal clear appearance. Turned into a piece of dead ashes.

The Thunder Dragon took the opportunity to drill out of the mouth of the ghost-headed ice eel and successfully passed through the crystal wire net!

"According to my analysis, the large array composed of one hundred and eight bronze giant pillars should be some kind of transformation of the 'Dutian Demon Thunder Array', if this is the case, its spiritual energy circulation pattern should be dominated by the 'Anti-Seven Palaces' form."

"Ancient cultivation 40,000 years ago. The study of spiritual patterns is not as delicate as that of modern people. When they set up such a large array, they would definitely leave behind several very thick psionic energy pipes, allowing the strong psionic energy to flow endlessly. ”

"So, the position I'm looking for is...... Over here! ”

In Li Yao's mind, a shiny three-dimensional structure diagram of the formation appeared. He harnessed the Thunder Dragon, zigzagging and twisting through the drains, and finally came to a stop at an unremarkable corner.

If he's not wrong, here. It should be a straight-line distance, the closest point to the center of the ban!

"Boom!"

The miniature Darklight drill bit kicked in quickly, burrowing deep into the icy rock.

Li Yao absolutely believed in his calculations, and drilled in the dark very patiently, and after twenty-seven minutes, the pressure of the Xuanguang drill bit lightened, and a long and narrow passage appeared in front of him, about half a foot in diameter, and the highly concentrated thunder and lightning spirit energy flashed through it, and there was a faint sound of thunder.

"It worked!"

"This is really the psionic energy circulation pipeline of the Great Array!"

Li Yao's excitement caused the Thunder Dragon to raise its special psionic shield against thunderstorms and swim upstream in the circulating pipe.

After flashing several arcs, several neatly arranged holes appeared in front of it, and the Thunder slid out lightly.

This is a large underground space, and there is a magnificent and domineering array engraved on the ground, as if tens of thousands of lightning bolts are imprinted together.

Above the large array, there were one hundred and eight bronze plates suspended in mid-air, and each bronze plate was also engraved with a dense rune array.

The bronze plates are connected by arcs, and the intricate arcs are almost like dozens of cobwebs overlapping each other, making people dizzy to watch.

Li Yao watched it with relish.

"Sure enough, it is a certain variant of the Dutian Demon Thunder Array, relying on the frosty aura and chaotic magnetic field of the Arctic region, it has been fine-tuned and strengthened, and it is even sharper than the original version of the 'Dutian Demon Thunder Array'!"

"The predecessors who laid down this big array are so extravagant, they actually found one hundred and eight pieces of 'Burning Star Copper' to act as the eye of the array, tsk tsk, I want to get a fist-sized piece of Burning Star Copper to strengthen the conductivity of the war knife, it took a lot of effort!"

"Just ......"

"This big array, it seems to have been transformed?"

"Yes, it's the handwriting of the Youquan Ancestor, and the hundreds of rune arrays used by the Dutian Demon Thunder Array have long been lost, and ordinary people can't understand it, let alone use it."

"Therefore, Youquan Ancestor used the technology of the Blood Demon Realm and the Tianyuan Realm to 'modernize' the Dutian Demon Thunder Array."

"It's ...... It's a mess, it's a terrible thing! ”

Li Yao pursed his lips, looking down on the transformation of Youquan Ancestor.

"Next, look at me!"

Li Yao knew that the center of the Dutian Demon Thunder Array would emit a large amount of violent thunder and lightning spiritual energy, forming arcs of lightning and lightning, not only could ordinary people not stay here for too long, but even monitoring magic weapons such as crystal eyes or biochemical eyes would not take half a day before they would be interfered with or destroyed by thunder and lightning.

Therefore, he was relieved and bold to let the Thunder Dragon gallop up and scan every detail of the large array.

"It seems that the Heavenly Great Array is composed of thousands of rune arrays, but the core is those key rune arrays, which lead the whole body."

"What I want to do is to slightly change the direction of the spiritual energy of these rune arrays, let them conflict with each other, and eventually cause the spiritual energy to be overloaded, and the 'Dutian Thunder Demon Suppression Array' will be abolished!"

The Thunder Dragon was like a sneaky rat, sowing a deadly plague, and under Li Yao's crazy calculations, miniature crystal shells were arranged one by one in the key parts of the large array.

After the five crystal shells were set up, his transformation plan was also concluded.

A milky white light shot out from the "Xuanguang Pen", beating lightly on the core spirit runes of the large array, and the pen walked the dragon and snake, and in a short time, hundreds of hair-thin spiritual patterns were added, forming a spiritual energy circuit full of evil energy.

"Phew! Phew! ”

Thunder and lightning constantly bombarded the Thunderdragon's psionic shield.

The Thunder is crumbling, and the shield will soon be gone.

"That's it!"

Li Yao whistled lightly and drove the Thunder Dragon back the same way.

Next, as long as his mind moves and activates the crystal marrow bomb, there is a high chance that he will be paralyzed by the "Dutian Demon Thunder Array"!

However, it is better to wait for the full force of the large array to drive before starting, so that the success rate is relatively high.

Li Yao pondered, now he can go and say hello to Han Tuhu.

"Drop! Drip! Drip! Drip! ”

Just as the Thunder re-burrowed back into the drain, it heard a rapid beep from the depths of the captive camp, as if something big had happened.

"Make no mistake!"

When the Thunder Dragon drilled out of the ice sea and flew into the air again, Li Yao was stunned by everything in front of him.

The human captives and the demon captives actually fought again.

And this time the fight is more fierce than a day ago, the two sides are like having an enmity with each other, hugging each other to the death, picking with claws, biting with fangs, you insert my eyes, I dig your crotch, under the blur of flesh and blood, it is really difficult to distinguish, who is a human and who is a demon!

"I'm in trouble!"

Li Yao was so anxious, looking at the life and death between the captives, even if he destroyed the Dutian Demon Thunder Array, he was afraid that it would be useless!

The two leaders, Han Tuhu and Suo Chaolong, even hit a real fire, and with every bombardment, the entire prisoner camp seemed to shake, and the ground was covered with footprints like craters when they rushed with all their might!

"Zizizizi!"

The one hundred and eight bronze towers around it once again released a powerful arc of electricity.

Ten seconds later, all the captives except Han Tuhu and Suo Chaolong were lying on the ground, pumping straight like shrimp.

And when the rest of the arcs were concentrated on the two leaders for three or four seconds, they also foamed at the mouth, their eyes bulged, and they fell on their backs, and started a sheep epilepsy.

Li Yao's brows were about to cry.

The plan must not be postponed, the hole he made in the drainage canal will not be discovered in a long time, and the fire ant king can definitely not help the destruction of brain cells by the "mad doctor" Lu Wuxin, which has nothing to do with willpower.

Wait until tomorrow and it's all over!

What to do?

Li Yao regretted a little that he didn't get in touch with Han Tuhu earlier, so that he could be a little more restless.

Dozens of Youfu soldiers reappeared, dragging the paralyzed captives back to the ground one by one, and this kind of brawl seemed to repeat itself every once in a while, and they were already familiar with it.

That's when an amazing change happened!

When several Youfu soldiers walked to Han Tuhu and Suo Chaolong's side, the two leaders, who were supposed to beat each other's dog brains and were electrocuted, actually jumped up together.

"Do it!"

The two of them shouted at the same time, and their speed soared to the limit, three times faster than just now!

They all hide their strength!

After genetic modulation again and again, their strength is stronger than that of ordinary Youfu troops, and these Youfu troops were deceived by their illusion of being in the same situation in the past, and thought that they were really seriously injured, caught off guard, and were hit on the spot! ――

Roar, roar, roar! Fourth Update! It is also the fourth watch that the people like to see! (To be continued.) )
