Outside, Yan Xu was suspended above the Zichuan Demon Cave, looking at the rolling thunderclouds in the sky with a resolute expression. ﹎8＿﹎＞ =`·．

The Heavenly Tribulation Thunder Punishment, the Heavenly Tribulation Thunder Punishment in the Merge Period, is far more than a hundred times more powerful than the Thunder Tribulation in the Distraction Period, and the power of the thunder and lightning is still superimposing.

"Come on, come on!"

A smile rose at the corner of Yan Xu's mouth, and he opened his arms to meet the Heavenly Tribulation Thunder Punishment.

For a while, the entire Zichuan Demon Cave once again turned into a sea of thunder, and the dilapidated buildings were completely blasted into powder by the aftermath of the thunder and lightning, and the radius was razed to the ground for thousands of miles.

If Chen Miaoxue and the others were not included in the inner world by Yan Xu, 300,000 people would not be able to escape death if they were buried in Lei Hai.

The reason why the hundreds of thousands of demons outside the heavens were blasted to the ground was not only the impact force generated by Yan Xu's fall, but also the power of thunder and lightning accounted for the main factor.

If it weren't for the formation of a defensive array by the demons outside the sky, I was afraid that the moment Yan Xu landed, the Zichuan Demon Cave would be completely wiped out.

Yan Xu comprehended the law in the chaotic space, and was not disturbed by the slightest thunderstorm, and broke through to the middle stage of the merger without hindrance.

With such a breakthrough that defies common sense, it would be fine if Yan Xu had stayed in the chaotic space all the time, but once he returned to Luo Tianda 6, he would inevitably be punished by several times the original Heavenly Tribulation.

"The Thunder Tribulation that broke through the Merge Period during the Distraction Period was already very powerful, coupled with the completion of the world in my body, under the superposition of the three major elements, the power of this Heavenly Tribulation was unimaginable. 8 '=-.=" Yan Xu blocked one thunderstorm after another, and his arms were numb.

This has just begun, the power of the Thunder Tribulation is so terrifying, what should the last few waves of Thunder Tribulation be, Yan Xu's face was slightly pale.

The greater the power of the Thunder Tribulation, the better the effect of refining the physical body, of course, the premise must be that you can withstand the test.

Yan Xu's arms were like a dark iron gate, blocking all the thunder tribulations. After carrying this wave of thunderstorms, Yan Xu looked down at the huge pit under his feet thoughtfully.

"This is an important stronghold of the Outer Demons, and there is definitely an ulterior secret that has been painstakingly melted and poured so much slag into the ground."

Yan Xu has been away from Luo Tianda for more than 6 or 30 years, and he has been away from the North Star Continent for two or three hundred years, and it is not known to what extent the Outer Heaven Demon has expanded in the North Star Continent and the Ice Pole Continent.

But judging from the scale of the stronghold here and the number of Terran monks captured, Yan Xu believed that the situation in the North Star Continent and the Ice-Arctic Continent was not optimistic.

Back then, the wisp of evil demon primordial god who entered Zhongzhou with Yan Xu never showed his 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 rest assured.

After thinking for a moment, Yan Xu flew to the bottom of the giant pit, just now he came out in a hurry to save people and did not check carefully. _>_> ''·. `ｙ=ａ``ｅ`ｎ-８`．=ｃｏｍ

The rock walls around the pit are covered with countless tunnels, which have been around for a long time judging by the texture of the rocks, and have been winding and spreading all the way to the ground.

Obviously, before Yan Xu arrived, the Outer Heaven Demon Trend Enslaved these tunnels in the ground.

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

The thunderclouds rolled and roared, and one after another thunderbolts struck again and followed into the huge pit, Yan Xu calmly carried the thunder tribulation and continued to explore below.

Yan Xu raised his hand with a sword qi and cut a hole horizontally on one of the rock walls of the deep pit.

Through this excavated passage, Yan Xuxian's entire underground of the Demon Cave was covered with this tunnel, spreading all the way to the depths of the ground.

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

There are more than 10,000 black refining towers in the entire Zichuan Demon Cave, and the dense 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 slimy paste, because the high temperature generated by the thunder and lightning was baked into such a dry solid.

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

"These smelts have the effect of banning aura, and they are also corrosive, what is hidden underground?" Yan Xu continued to fly downward, and the light became dimer and dimmer.

Deep underground, Yan Xu touched a thick layer of pitch-black rock, this layer of rock was dozens of miles thick, and it was all made of refining slag.

The thoroughly cooled slag rock layers were very hard, completely cutting off the underground from the outside world, but they were vulnerable in front of Yan Xu.

Yan Xu blasted out with a punch, blasting the black slag rock layer out of a large hole, and a thick aura erupted from the ground.

"Spirit Stone Vein!" Even if Yan Xu was prepared, he was still taken aback.

This is a huge vein of top-grade spirit stone, Yan Xu has been digging along the ground, and now this spirit vein is at least more than a thousand miles long.

The giant 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 number of spirit stones rich in them is amazing.

"Ice-Arctic has such an amazing spiritual vein? How is this possible? ”

As far as Yan Xu knew, since the Great War of the Ancients, the aura of the North Star Continent and the Ice Pole Continent had become thinner and thinner, and it was impossible for such an amazing spiritual vein to exist.

With the existence of such spiritual veins, a special terrain will inevitably be formed in this area, resulting in a blessed land that all sects must compete for, and even the aura that can drive the entire continent of the Ice Polar Continent will be much better.

Yan Xu frowned and thought for a moment, then said to himself: "I see, the Outer Heaven Demon is afraid that the existence of this spiritual vein has appeared since ancient times, and it has been sealed and hidden by special means. Now, the Polar Continent has completely fallen into their grasp, and they have begun to use their means to refine this spiritual vein. ”

The Outer Heaven Demons, both in terms of physique and exercises, were different from Luo Tianda 6, and they could not directly absorb the spiritual energy in the spirit stone.

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

These molten slags with a banning effect do not know how to hide and isolate the spiritual vein, and their colleagues are also corroding and devouring this spiritual vein, continuously providing essence energy to the demons outside the sky.

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

Back then, the aura of the Tianhao Sect was declining day by day, wasn't there also a magic circle arranged by the demons outside the sky? The situation here is similar to that of Tianhao Sect, except that the scale is much larger.

"The aura of the North Star Continent and the Ice Polar Continent has become thinner, and the decline of the qi luck is all the secret troubles of the evil demons outside the sky!"

Yan Xu hated the earth, and the strategy of the Outer Heaven Demon was not clever, which could not only weaken the strength of Luo Tianda's 6 cultivation realm, but also secretly enhance his own strength.

Under the advantages of one another, one day Luo Tianda 6 will completely fall into the hands of the demons outside the sky.

Thinking of the law passage outside the Luo Tianda 6 crystal wall that didn't know where it led, Yan Xu couldn't help but break out in a cold sweat.
