During the peak period, the food, drinking, defecation and scattering of tens of thousands of prisoners will definitely produce a large amount of waste and wastewater. The wastewater in it will be directly discharged into the ice sea through drainage canals located below the sea surface.

The diameter of each drain pipe is more than half a meter, and an adult can easily get in. Because of this, the ancestor Youquan set up a dense crystal wire mesh on the opening of the drain pipe, and was covered with defensive talisman arrays, which can pass super electric arcs and extremely mysterious cold air to the crystal wire mesh.

If you forcibly destroy the crystal wire mesh, you will definitely be perceived by the guards above.

The hole of the crystal wire mesh was too narrow, and Li Yao was not sure that he could control the Xiaolong, and he crawled in without knowing it.

However, this could not defeat him.

He drove the Xiaolong diving deeper and deeper, and came to a six or seven hundred meters bottom of the sea. After waiting quietly in a trench for a while, he found a congee that was more than half a foot long and crystal clear all over his body.

This light blue monster that has no eyes and can hardly distinguish the head and tail is called "ghost-headed ice eel". It is one of the few monsters that can survive in the Arctic ice sea.

Originally, they would not live near the Yinfeng Islands so north, but Li Yao estimated that the large amount of wastewater and garbage discharged from the "You Mansion" contained certain nutrients, which attracted these ghost-headed ice eels, and came here without fear of the cold and whirlpool.

Generally speaking, ghost-headed ice eels like to live in places with 300 to 800 meters underwater and sunny.

However, when they are hungry, they will also risk floating up to about a hundred meters under the water to find food.

Especially the drainage outlets rich in a lot of garbage are their favorites.

Often, ghost-headed ice eels will drill into the drain, accidentally touch the crystal wire mesh, and be killed by arcs and frost.

Li Yao also found half of the bones of a ghost-headed ice eel at the entrance of a drainage channel during his survey yesterday. After careful consideration, he realized this truth.

"Swoosh!"

When the ghost-headed ice eel opened its round mouthpiece, swallowing the gravel on the seabed and sucking nutrients from it, the Xiaolong turned into a stream of light and pierced deeply into its mouth!

The ghost-headed ice eel jumped suddenly and was instantly killed by the Xiaolong.

The Xiaolong crawled into the mouth of the ghost-headed ice eel. He regarded it as the best disguise and swam towards the drainage channel.

When approaching the crystal wire mesh, Li Yao did not dodge at all, and just swayed and bumped into him!

"Shit and shit!"

A dark blue electric arc burst out on the crystal wire mesh instantly, which made the ghost-headed ice eel straight, and its originally crystal clear appearance turned into a dead ashes.

However, the Xiaolong took the opportunity to drill out of the ghost-headed ice eel's mouth and successfully crossed the crystal wire mesh!

"According to my analysis, the large array composed of one hundred and eight giant bronze pillars should be a kind of deformation of the "Dutian Demon-Subduing Thunder Array". If so, its spiritual energy cycle pattern should be mainly in the "anti-seven palace" form."

"The ancient cultivators 40,000 years ago did not have as fine research on spiritual patterns as modern people. When they arranged such a large array, they would definitely leave several very thick spiritual energy pipes, allowing powerful spiritual energy to flow continuously."

"Then, the location I'm looking for is... here!"

A shiny three-dimensional structure diagram of the formation appeared in Li Yao's mind. He was driving the Xiaolong, twisting and twisting in the drainage channel, and finally stopped at an ordinary corner.

If he did not calculate correctly, this should be a straight line distance. The point closest to the ban center!

"Swish, swish, swish!"

The miniature black light drill bit quickly started and drilled deep into the cold rock.

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

"Success!"

"This is really the spiritual energy circulation pipeline of the large array!"

Li Yao was excited and raised the Xiaolong to protect the thunderstorm-specific psychic shield, which was used to defend against thunderstorms, and went upstream in the circulation pipeline.

After several electric arcs flashed, several neatly arranged holes appeared in front of them, and the Xiaolong came out lightly.

This is a wide underground space, with a magnificent and domineering array engraved on the ground, as if it had imprinted tens of thousands of lightning together.

Above the formation, there were still 108 bronze plates floating in the air, and each bronze plate was also engraved with dense talisman arrays.

The bronze plates are connected by arcs. The intricate arcs are like overlapping dozens of spider webs, making people dizzy.

Li Yao watched it with relish.

"It's indeed a variation of the Dutian Demon-Suppressing Thunder Array. Relying on the frost breath and disordered magnetic fields in the Arctic region, it has been finely tuned and strengthened, which is more sharp than the original version of the "Dutian Demon-Suppressing Thunder Array"!"

"The senior who set up this big array is so luxurious. He actually found 108 pieces of 'Rich Star Copper' as the array eye. Tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk

"only……"

"This big array seems to have been transformed?"

"Yes, it's the work of the ancestor Youquan. The hundreds of talisman arrays used by the Dutian Demon-Suppressing Thunder Array have long been lost. Most people can't understand it, let alone use it."

"So, the ancestor Youquan used the techniques of the Blood Demon Realm and the Tianyuan Realm to "modernize" the Dutian Demon-Suppressing Thunder Array."

"It's really... a mess, a waste of resources!"

Li Yao curled his lips and looked down on the transformation of the ancestor Youquan.

"Next, let's see mine!"

Li Yao knew that the center of the Dutian Demon-Subduing Thunder Array would emit a large amount of violent thunder and lightning psychic energy, forming a series of rapid lightning arcs. Not only can ordinary people not stay here for too long, but even surveillance magic weapons such as crystal eyes or biochemical eyes will not take a long time to be disturbed or destroyed by lightning.

So, he was relieved and bold to let the Xiaolong rush and scan every detail of the array.

"It seems that the Dutian Array is composed of thousands of talisman arrays, but the core is those key talisman arrays, which will drive the whole body."

"What I have to do is to slightly change the spiritual energy direction of these talisman arrays, let them conflict with each other, and eventually lead to a spiritual energy overload, and destroy the "Dutian Thunder Demon-Subduing Array"!"

The Xiaolong is like a sneaky mouse, scattering a deadly plague. Under Li Yao's crazy calculations, miniature marrow-crystal bombs are arranged one by one in the key parts of the formation.

After the five crystal marrow bombs were set up, his transformation plan also came to a conclusion.

A milky white light shot out from the "Xuanguang Pen", which was jumping lightly on the core spiritual talisman of the formation. The pen was like a dragon and a snake. In a short while, hundreds of thin spiritual patterns were added, forming a series of spiritual energy circuits full of evil spirits.

"Chi!Chi!"

Lightning continued to bombard the virility shield of the Xiaolong.

The Xiaolong is shaking and the shield is about to disappear soon.

"It's done!"

Li Yao whistled softly and returned on the same route as the Xiaolong.

Next, as long as he thinks and stimulates the crystal marrow bomb, there is a high chance that he will paralyze the "Dutian Demon Subduing Thunder Array"!

However, it is best to wait until the formation is fully driven before taking action, so that the success rate is relatively high.

Li Yao thought that he could go and say hello to Han Tuhu now.

"Drip!Drip!Drip!"

Just as the Xiaolong re-dived back into the drainage channel, he heard a rapid beep deep in the prisoner camp, as if something big happened.

"Are you wrong?"

When the Xiaolong crawled 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 started fighting again.

And this time the fight was even more fierce than a day ago. The two sides seemed to have an irreconcilable hatred. They hugged each other tightly, clenched with their claws, bite with their fangs, you inserted your eyes, I sucked your crotch, and it was really hard to tell who was human and who was a monster!

"It's a problem now!"

Li Yao was anxious. Looking at the life-and-death look of the prisoners, even if he destroyed the Dutian Demon Subduing Thunder Formation, it would be useless!

The two leaders, Han Tuhu and Suo Chaolong, even fired real fire. With every bombardment, the entire prisoner camp seemed to shake, and the ground was covered with footprints of their full sprints, like craters!

"Sizi!"

The 108 bronze giant towers around once again released an unparalleled electric arc.

More than ten seconds later, all the prisoners except Han Tuhu and Suo Chaolong were lying on the ground, thrusting like shrimps.

And when the remaining arcs were concentrated on the two leaders for three or four seconds, they foamed at the mouth, their eyes burst, and fell on their backs, causing epilepsy.

Li Yao's brows were almost crying.

The plan must not be postponed. The hole he dug in the drainage can be discovered soon. The Fire Ant King will definitely not resist the destruction of brain cells by the "crazy doctor" Lu Wuxin, which has nothing to do with willpower.

Wait until tomorrow, everything is over!

what to do?

Li Yao regretted it a little and did not contact Han Tuhu earlier, so that he could not rest assured.

Dozens of Youfu Army appeared again, dragging the limp prisoners back to the ground one by one. This kind of fight seemed to happen again every now and then, and they were already familiar with it.

At this moment, an amazing change occurred!

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

"Do it!"

The two shouted loudly at the same time, and their speed reached its limit, three times faster than before!

They all have hidden strength!

After repeated genetic modulation, their strength was stronger than that of the ordinary Youfu Army. These Youfu Army were blinded by the illusion of their past power and fire. They thought they were really seriously injured, caught off guard, and were hit on the spot!—
Chapter completed!
