Chapter 693 The Secret Under the Devil's Nest
Outside, Yan Xu hovered above the Zichuan Demon Cave, looking resolutely at the rolling thunderclouds in the sky.

The Heavenly Tribulation Thunder Punishment, the Heavenly Tribulation Thunder Punishment in the Fusion Stage, is more than a hundred times more powerful than the Distraction Stage Thunder Tribulation, and the power of thunder and lightning is still superimposed.

"What should come will come, come on!"

A smile rose from the corner of Yan Xu's mouth, and he opened his arms to meet the thunder and punishment.

For a moment, the entire Zichuan Devil's Cave turned into a sea of ​​thunder again, and the dilapidated buildings were completely pulverized by the aftermath of the lightning, and they were razed to the ground for thousands of miles.

If Chen Miaoxue and others hadn't been taken into Yan Xu's internal body world, all 30 people would have died in Leihai.

The reason why the 10,000+ extraterrestrial demons were blasted to nothing is not only the impact of Yan Xu's fall, but the power of thunder and lightning is the main factor.

If it wasn't for the formation of a large defensive formation by the evil spirits from outside the sky, I'm afraid that Zichuan Devil's Cave would have been completely wiped out the moment Yan Xu just landed.

Yan Xu comprehended the law in the chaotic space, without being disturbed by the slightest thunder calamity, and broke through to the middle stage of integration without hindrance.

For such an unreasonable breakthrough, it would be fine for Yan Xu to stay in the chaotic space, but once he returns to the Luotian Continent, he will be punished several times the original Heavenly Tribulation.

"The thunder calamity that breaks through the fusion stage in the distraction stage is already very powerful. Coupled with the great achievements of the world in my body and the superposition of the three elements, the power of this catastrophe is beyond imagination." Yan Xu blocked one thunder after another. Jie, his arms were numb from the shock.

This is just the beginning, the power of the thunder calamity is so terrifying, what is the magnitude of the last few waves of thunder calamity, Yan Xu's face is slightly terrified.

The greater the power of the thunder calamity, the better the effect of tempering the body. Of course, the premise must be that one can withstand the test.

Yan Xu's arms were like a black iron gate, blocking all of Lei Jie.After surviving this wave of thunder disaster, Yan Xu looked down at the huge deep pit under his feet thoughtfully.

"This is an important stronghold of the evil spirits outside the sky. There must be a secret to be smelted so much slag has been poured into the ground after hard work."

Yan Xu has been away from Luotian Continent for more than 30 years, and he has been away from Beixingzhou for two or 300 years. It is not known to what extent the evil spirits outside the sky have expanded in Beixingzhou and Bingjizhou.

But judging from the size of the stronghold here and the number of captured human monks, Yan Xu believes that the situation in Beixingzhou and Bingjizhou is not optimistic.

At that time, the ray of evil spirit that entered Zhongzhou with Yan Xu never found its whereabouts, and it was always a problem in his heart. If he didn't find out the situation in front of him, Yan Xu couldn't be at ease.

After thinking for a moment, Yan Xu flew to the bottom of the huge pit. Just now he was in a hurry to save people and did not check carefully.

The rock walls around the deep pit are covered with countless tunnels. Judging from the texture of the rocks, these tunnels have existed for a long time, and they twist and turn and spread all the way to the ground.

It is obvious that before Yan Xu's arrival, the demons from outside the sky dug these tunnels underground.

Because of this, Yan Xu would sink into the ground for hundreds of miles after hitting the ground, otherwise such a deep pit would not have occurred.

Thunder clouds rolled and roared, and thunder and lightning struck again and then blasted into the huge pit. Yan Xu calmly carried the thunder disaster and continued to explore below.

Yan Xu raised his hand with a sword aura, cutting a hole across the rock wall of the deep pit.

Through this excavated passage, Yan Xu found that the entire underground of the magic cave is covered with tunnels, spreading to the depths of the ground.

With the smelting tower as the center, the tunnels are most densely distributed, and the black smelt flows into the ground along the tunnels.

There are more than 1 black melting towers in the entire Zichuan Demon Cave, and densely packed tunnels lead to the ground, like a big sieve buckled on the ground.

Yan Xu picked up a piece of black iron-like slag, which should have been a sticky paste, because it was baked so dry by the high temperature generated by lightning.

Yan Xu pinched it lightly, and the molten slag turned into fly ash, and a foul smell wafted out.

"These smelts have the effect of sealing spiritual energy, and they are also corrosive to a certain extent. What is hidden in the ground?" Yan Xu continued to fly down, and the light became increasingly dim.

In the depths of the ground, Yan Xu touched a thick layer of pitch-black rock. This layer of rock is dozens of miles thick, and it is all made of refined slag.

The completely cooled slag rock formations are very hard and completely cut off the ground from the outside world, but they are vulnerable to Yan Xu.

Yan Xu punched out a big hole in the black slag layer, and a strong spiritual energy gushed out from the ground.

"Lingshi vein!" Even though Yan Xu was prepared, he was still taken aback.

This is a huge top-grade spiritual stone vein. Yan Xu dug along the ground and found that this spiritual vein is at least a thousand miles long.

The huge top-grade spirit stone veins, only the main trunk is a thousand miles long, and the branch veins derived from it add up to thousands of miles, and the amount of rich spirit stones is astonishing.

"Ice Pole Continent has such an astonishing spiritual vein? How is this possible?"

According to Yan Xu's knowledge, since the ancient war, the aura of Beixing Continent and Bingji Continent has gradually become thinner, and it is impossible for such an astonishing spiritual vein to exist.

With the existence of such spiritual veins, this area will inevitably form a special terrain, creating a paradise for all sects to compete for, and even the aura that can drive the entire continent of Bingjizhou will be much better.

Yan Xu frowned and thought for a moment, then said to himself: "So that's the case, the evil spirits from the sky may have discovered the existence of this spiritual vein since ancient times, and sealed and hidden it with special means. Now, Bingjizhou has completely fallen into their control. Only then began to use their methods to refine this spiritual vein."

The evil spirits outside the sky are different from the Luotian Continent in terms of physique and skills. They cannot directly absorb the spiritual energy in the spirit stone.

However, with the help of special means, spirit stones still have a huge effect on them, and can be transformed into substances that can be absorbed by the demons outside the sky.

These slags with a sealing effect do not know how to hide and isolate the spiritual vein, and colleagues are also corroding and devouring this spiritual vein, continuously providing energy to the evil spirits outside the sky.

Although it was just his own guess, Yan Xu believed that it was not far from the truth.

Back then, the aura of Tianhaozong was declining day by day, didn't there also be a magic circle arranged by the evil spirits outside the sky?The situation here is similar to that of Tianhaozong, but the scale is much larger.

"The aura of Beixing Continent and Bingji Continent has become thinner, and the decline of luck is due to the evil spirits from outside the sky!"

Yan Xu bitterly said that the strategy of the evil spirits outside the sky is not unreasonable. It can not only weaken the strength of the Luotian Continent's cultivation world, but also secretly strengthen its own strength.

Under the ebb and flow, one day the Luotian Continent will completely fall into the hands of the evil spirits from beyond the sky.

Thinking of the passage of law leading to nowhere outside the crystal wall of Luotian Continent, Yan Xu couldn't help breaking out in a cold sweat.
