There is no end to the road, hope is around the corner.

Xiao Nu, who slipped at high speed in the dark, always kept his body in the best state of protection, and finally opened his eyes, and ran the smoke and mysteries with all his might, his body was like light smoke, and he instantly entered a mysterious state that could be fast or slow, and the priorities were all under his control.

Xiao Nu didn't know that all the ninety-eight sand swallowing ants after his contract had advanced to three stars, and in the historical records of Yuanmeng, there had never been a three-star sand swallowing ant, and he didn't know that he had changed the history of Yuanmeng and broken some rules in the biological world.

He just felt very interesting, and the head ant behind him was now communicating with his thoughts more clearly and smoothly, not only picking up the lost letter but also chasing after him, even if he tried his best to spread the smoke method, he could not shake it off, as if they had transformed into the real kings of the underground world, and walked through the underground like a fish in water.

The head ant does not glide like Xiao Nu, its two horns are simply more powerful than the sharpest shovel, and in the high-speed movement, all the dirt and rocks that stand in its way are instantly shattered by its two horns.

Xiao was furious, it turned out that this underground passage was formed in this way.

Because the deeper you go underground, the more scarce oxygen becomes, Xiao Nu has to run the Qingxi Jue with all his might, and strive to create internal circulation in the body, replacing external breathing with internal breathing.

I don't know how long it took to walk, but the eyes suddenly opened up, and the momentum of gliding decreased sharply, Xiao Nu took away his body and stood still, but he was completely sluggish like a clay sculpture.

Because, there is a very wide and flat underground square here. Filled with an eerie light purple mist, the head ant was very frightened, and frequently urged Xiao Nu to leave here quickly.

But Xiao Nu was not suddenly sluggish, but recognized the strange underground square in front of him, which was obviously excavated by hand, and after he upgraded to the intermediate detection technique, he could clearly see the foggy places at the edge of the square, and there were countless corpses buried underground!

"Who the hell excavated such a strange underground square under Qingxi City, and what is the purpose?" Xiao Nu had countless questions rolling in his heart.

However, Xiao Nu still took out the elixir given to him by Teacher Lin Yan first, and basically cured his broken leg after three refinements, and felt that the injury in his body had slowed down, and he would be fine after resting for a while, so he stabilized his mind.

Seeing that the master had no intention of leaving, the head ant was not urging, but the horn gently vibrated towards the other end of the passage it dug, if it weren't for Xiao Nu's ears and eyes now being different from before, he wouldn't have sensed that the head ant was vibrating a special syllable with the horn at the moment to convey some kind of message to whom.

In the perceiving world, he noticed that more than ninety sand swallowing ants were gathering rapidly towards this side in the distance, Xiao was relieved, and told the head ants not to move, and pay attention to other terrifying star insects and star beasts around him, while he was engrossed in that strange square.

After running the detection technique with all his might, the mist-obscured square slowly began to show its true face in Xiao Nu's vision, and Xiao Nu couldn't help but be surprised when he saw it clearly.

Although Xiao Nu's current level of array hunting skills is barely maintained at three stars, because the array hunting technique has already been upgraded to the intermediate level in the enlightenment platform, the magic array and hunting techniques within the six stars cannot escape Xiao Nu's discerning eye.

When the detection technique was urged with all its might, countless arrays of mysteries of hunting techniques flowed through Xiao Nu's heart, and combined with the various analyses of this strange square in the field of vision, a string of information soon surfaced in Xiao Nu's mind.

"Quartet extinction, ecstasy, blood river trap, six stars. This array needs to be equipped with four sub-array platforms, mainly guided by the blood and soul of tens of millions of human beings, after opening the four arrays in one, within 120,000 miles, the living beings will be extinct, and all things will be annihilated into the invisible, and there is a one-third chance of opening up a Demon King Domain Void Channel. ”

This first half of the information alone made Xiao Fu's hands and feet cold, like falling into an ice cave.

If this is really a sub-formation platform, then who is quietly laying down here and hiding from many powerhouses in the Eastern District?

Why did the person who set up the formation want to open the void passage to the Demon King Domain, and what did he want to do?

Today's Xiao Nu is no longer Wuxia Ameng, he has learned from the Enlightenment Star that the empire has expeditionary operations in both low-level and high-level regions. The Void Passages used are all guarded by the powerhouses of the Empire or the Great Family, which can be described as foolproof and completely reliable.

Even the peerless powerhouses of the Star Emperor and the Star Emperor will not open the void passage to the Demon Domain at will, what if they recruit the hundreds of millions of peerless powerhouses of the Demon Race?

Xiao Nu instantly seemed to smell some kind of strong conspiracy.

According to the feedback from his consciousness, he began to scan the square in front of him with all his might, for the sake of caution, he must verify them one by one, this is not a trivial matter, it is completely beyond the control of Xiao Fu's ability!

I don't know if I have a deep hatred for the demon clan in my bones, at this time, Xiao Nu completely forgot about other things, such as the upcoming auction of the Alchemy Star Pavilion, how to help Zhao Qiming clear his grievances, and so on. Compared to this incident, other things are not worth talking about at all.

In the dark, Xiao Nu felt that there was something in his blood that had been lurking deep for a long time and quietly revived, but he didn't know what it was, but he felt that he almost couldn't control the boiling roar of his blood at the moment, and there was a transcendent sense of justice flowing in his blood, as if he was already a guardian standing at the peak of mankind at this moment.

This feeling is too mysterious, but it is undoubtedly the realm that Xiao Nu longs for and tirelessly pursues.

Once upon a time, he imagined countless times that if one day, he lit the star lantern, no matter what, he couldn't live his life with his pockets, and he would die on the battlefield of the expedition, so that even if he was not qualified to marry His Royal Highness the Nineteenth Princess, the regrets of this life would be erased.

The division platform in front of him, Xiao Nu completely regarded it as his first expedition to the battlefield, extremely cautious, extremely excited, so that his blood boiled and he had a kind of ardent desire to kill the demons of the Quartet with a sword.

Can't stop!

He made up his mind that once he confirmed that this sub-array was the genus of the Quartet Extermination Ecstasy Blood River, then he had to immediately return to the academy and inform the two people he felt most trusted: Teacher Lin Yan or Beard.

Therefore, despite being very excited, Xiao Nu quickly calmed down and began to do his best to identify and authenticate.

The purple dense mist, the main material is the six-star eclipse sky flower, the six-star three-eyed demon bear bile, and the six-star shadowless demon bee venom, which are three rare poisonous materials unique to the exotic demons, plus six kinds of five-star poison mixed and refined, this kind of purple fog that is dedicated to the forbidden magic circle that exterminates living beings such as the Quartet Extermination Ecstasy Blood River Trap has a name: Tanhua Mist.

Unless someone forcibly breaks into the platform, its daily function is not only the protective barrier of the platform, but also the continuous collection of the dead souls scattered between heaven and earth, and provides the platform so that it can be continuously refined.

The passage dug by the head ant was about 100 meters away from the square, and although the sand swallowing ants that kept gathering were very afraid of the sub-array platform, they obeyed the orders of the head ant and became Xiao Nu's guards, vigilantly guarding its surroundings, and did not interfere with Xiao Nu at all.

Xiao Nu didn't have time to spare, otherwise he would have been surprised, because the ninety-eight sand swallowing ants he had contracted had all broken the shackles of heaven and earth at their species level, and all of them had advanced to three stars. The three abnormal star patterns on the back shell are full of endless mysteries, and they seem to be much more advanced and mysterious than the star patterns of ordinary three-star insects.

After this group of sand swallowing ants advanced, it seems to have shrunk collectively, the head ant is the largest, and it is only the size of an adult's fist, which may have something to do with its advancement to the three-star high-level, and the rest of the sand swallowing ants are uneven, but they are basically maintained at the size of a baby's fist, and the whole body is dazzling white, as if they have reached the primary peak of the three-star level.

I don't know what this group of sand swallowing ants went through when they left the Nie family's No. 5 mine, and the collective advanced rapidly, completely breaking the historical rules of the Yuanmeng species!

It took Xiao Nu almost a cup of tea to confirm that this sub-array platform, which was completely shrouded in the flower mist, was one of the four directions of the Extinction Ecstasy Blood River.

"Exploring the flower mist and the blood river are the two major elements of the Quartet's extinction and ecstasy blood river. ”

Xiao Nu suddenly broke out in a cold sweat, and his wild thoughts made him get an extremely terrifying idea.

He has lived in the easternmost frontier of the empire since he was a child, and his footprints have covered the four major regions, and the most familiar is the bloody blood sand river.

I don't know where the source of this river is, but it surrounds the four regions of the Dragon Slayer Collar, like a blood-colored link, connecting the four regions together.

With Xiao Fu's array hunting technique at this moment, let him arrange this Quartet Extermination Ecstasy Formation, a sub-array platform in Qingxi City, so where are the other three sub-array platforms?

The location that meets this condition must be surrounded by a river of blood!

Xiao Nu seemed to feel that he had grasped the point all of a sudden.

But he didn't understand one thing, the Quartet Extinction Ecstasy Blood River Trap Formation was a very ancient six-star forbidden array, and it was definitely not something that an ordinary six-star magic circle master could handle. Moreover, for the establishment of a sub-array platform, if the materials required are converted into spirit stones, how much more than tens of millions?

Who has such majestic strength? Who wants to open up the passage of the Demon Domain?

Xiao Nu wanted to send a revelation from the sky to help him, but unfortunately he knew that this matter could not be relied on by heaven, and he had to rely on himself.

The operator of this matter is by no means simple, and his background, strength, and financial resources are not something that Xiao Nu can shake at all.

Xiao Nu thought that this sub-formation platform had been set up for at least six or seven years, and no one was aware of it, so it was conceivable that the person behind it was powerful and mysterious.

Even if he ran out and brought all the powerhouses of the entire Dragon Slayer Leader here, he believed that the person who set up the formation would have a way to deal with it.

"What should I do?"

Of course, Xiao Nu had seven ways to destroy this sub-formation platform, not to mention that he could do this, even if he could, he wouldn't dare to do it.

Because, the Quartet Exterminates the Ecstasy Blood River Trap has set up four sub-array platforms, if one of them is destroyed, the other three will burst at the same time, although its power can open the void channel, it is enough to make everything wither and extinct within a range of forty or fifty thousand miles!

If you want to completely abolish this array, you must find the other three sub-array platforms, and the four parties will work together to crack it, there is no other way!

Xiao was so anxious that he was about to return to the academy, when suddenly the head ant grabbed his trouser leg with a horn, and a vague message came from his mind.

Unable to resist the stubborn head ants, Xiao Nu had no choice but to give an order to all the sand swallowing ants not to approach here, and then used all his strength to open the smoke body method, and followed the head ants who led the way to the passage and quickly escaped.

In perception, Xiao Nu knew that he had gone out of the range of Qingxi City, and judged that the direction should be towards the east bank of the Blood Sand River.

As the passage became more and more wet, Xiao Nu knew that he was extremely close to the Blood Sand River.

At this moment, the head ant suddenly slowed down, and the end of the passage was impressively reached. Xiao Nu fixed his eyes and saw that there were four or five huge caves there, and Xiao Nu immediately sensed that there were many other kinds of star insects hidden in the caves, and the grades were not low.
