Hearing this, Sun Yan and Lao Zheng's hearts sank, neither of them spoke, but nodded silently in agreement. After that, the three of them did not speak again, and followed Harahara, crawling through the narrow passage.

A moment later, after a long time of walking through the interwoven passages like cobwebs, a wave of ripples came from above, and Sun Yan knew in his heart that they were about to reach their destination.

At the end of the passage was a small door, which was actually a hole in the wall of the alloy fortress, but Mo Feng, like Professor Luo, pursued perfection in everything. So, a small door was installed in the hole that had been hewn out. The material used to make this small door is still a D-grade alloy, which is quite expensive.

These narrow passages were all dug by Mo Feng and Yuan Yuan over the years, and the life in the underground camp was extremely boring, and there was no entertainment at all. Mo Fengchun used these passages as a secret stronghold between him and Yuan Yuan, but he didn't expect that they would come in such a handy today.

Pushing open the small door, Ling Zi took the lead in getting out of the way, and then motioned for everyone to follow.

Emerging from the small door, Sun Yan found that he was standing behind a huge warehouse, surrounded by rows of metal cabinets, all of which were 20 meters tall and 20 meters long and wide. Each metal cabinet is marked with a different color markings to distinguish them.

The purpose of these metal cabinets is to hold those cosmic garbage and waste, and these metal cabinets are equipped with automatic purification instruments, and some cosmic garbage can be converted into useful resources after being placed for decades or hundreds of years, and then reused as waste.

This kind of recycling device is the source of profit for many garbage stars, but now Sun Yan also understands that the real purpose of the existence of the Blade Mountain Cleaner Camp is just to provide camouflage for the existence of space nodes.

Everything here is nothing more than a façade.

Looking around, with the unusually keen perception of the three of them, they all noticed that there was a fluctuation here, and the entire space seemed to be slightly vibrating, and there was an extremely dangerous aura everywhere.

"Damn, Lao Tzu used to say that the conditions of the garbage place are better than the conditions we live in, and sure enough!" Ling Zi cursed in a low voice, alert to the situation around him.

After muttering a few words softly, Ling Zi stopped speaking, he motioned for Sun Yan and the others to wait in place, and went to explore the way around this warehouse first. In the blink of an eye, Ling Zi's figure flickered and disappeared in front of Sun Yan.

"Uh, it's gone?" Sun Yan couldn't help but be surprised, feeling incredible.

From the contact in the past two days, Sun Yan could probably figure out the bottom limit of Ling Zi's strength, which was about the level of an eighth-level martial artist. If the two go head-to-head, with the [Floating Light Earthquake Heavenly Technique], Sun Yan is even confident to have the upper hand.

After all, the two combat skills mastered by Sun Yan have mysterious origins and unpredictable powers, and they are far beyond the scope of ordinary combat skills. Unless it is a ninth-level great martial artist, the internal element communicates naturally, and gathers into a great Zhou Tian, which has reached the limit of the human body, and can also use the battle scar armament.

Only in the face of a real great warrior, Sun Yan has no certainty of victory, and can only avoid the edge for the time being.

However, Ling Zi's actions just now, Sun Yan didn't even notice how he disappeared, which couldn't help but make him feel suspicious.

Seeing Sun Yan's doubts, Lao Zheng said in a low voice: "This is the 'Hidden Shadow Technique', if it is strictly divided, it can be regarded as the category of the five-rank high-level combat skills, and it belongs to the body combat skills that are only circulated among the interstellar tomb robbers. By taking advantage of the environment, shadows and blind spots, you can achieve the effect of coming and going without a trace. After a long period of time, this kind of body technique has also derived various branches, and this 'Hidden Shadow Technique' that Ling Zi used should be regarded as an authentic kind of stealing the door. ”

Hearing this, Sun Yan couldn't help but be surprised, at the same time, his interest in his heart increased greatly, he didn't expect that there was such a wonderful body technique, and when this operation was over, he must take time to study it carefully.

At this moment, Ling Zi's figure appeared again, like a puff of light smoke, silently walking out of the shadows.

"Let's go, this is warehouse 5 of the alloy fortress, nothing happens. Ling Zi gestured.

Following behind Ling Zi, the three of them and one dog moved slowly in the shadows, and after a while, they came to the gate of this warehouse.

Lao Zheng made a gesture to signal the others to wait beside him, and he took out a detector, the size of a thumb, extremely delicate, and pasted it on the heavy alloy door of the warehouse.

The detector flashed in a circle of light, and in the blink of an eye, there was a faint sound, and in an instant, the warehouse alloy door was opened.

Seeing this, Sun Yan couldn't help but sigh and praised in a low voice: "This thing looks really good! Lao Zheng, give me a few in the future." ”

Listening to the young man's sincere exclamation, Lao Zheng couldn't help but be secretly proud, and was just about to say something. Suddenly, the faces of the three of them changed in unison, and their bodies retreated to both sides.

Whoosh!

Three black shadows pierced through the crack in the door, and they were actually three barbed rattans, the surface was gray-brown, and the diameter was half a meter thick, which was hideous and terrifying.

"Damn, Iron Thorn Vine!" Old Zheng suddenly changed color, gasped, and whispered.

As soon as the alloy door of warehouse No. 5 opened, three rattans, half a meter thick, like three giant pythons, slammed the heavy door open directly.

Bang bang bang!

After three muffled sounds, the alloy door of the warehouse opened, revealing the scene outside the gate. Outside Warehouse 5, as Mo Feng remembers, was a large control room, monitoring a series of warehouses in the western area of the Alloy Fortress. There are only a few robots in this control room, which are responsible for the day-to-day monitoring and maintenance of the equipment.

At this moment, the control room outside the warehouse gate was a messy and terrifying scene.

On the metal floor, the severed limbs of the robot were scattered everywhere, and the central control light brain was full of holes, and huge rattans drilled into it, slowly wriggling, and bursts of sparks flickered non-stop.

On the ground and on the walls, python-thick vines weave into a web, slowly wriggling like snakes, making a subtle sizzling sound. The severed limbs of the robots were entangled in rattan sticks and then twisted into pieces.

Seeing this scene, Sun Yan and the others couldn't help but be shocked, although these robots in the cleaner camp were implanted with a fairly simple intelligent program and could only perform some mechanical work, but the materials used to make these robots were real D-grade alloys, which were extremely strong.

These terrifying vines can easily twist the robot to pieces, and if they are replaced by flesh and blood, I am afraid that there will not even be a bit of scum left.

"Be careful, this is the [Iron Thorn Vine], which belongs to a mutated sixth-level alien beast. Ling Zi issued a warning.

Whoosh!

After the three rattans slammed open the alloy gate, they swept in all directions like three thick whips, and the fierce wind blowing up made Yuan Yuan stand unstable at all.

"Be careful!"

Sun Yan's face changed slightly, he stepped out in one step, stepping on the [Hurricane Step], and the next moment he had rushed behind Yuan Yuan, picked it up, and a transparent cyclone formed around him.

The cyclone swirled around its body, rubbing against a vine, making a cacophony like grinding teeth. Sun Yan took off in the air, his body spun in mid-air, and after a few ups and downs, he retreated to the edge of the wall.

And after these three [Iron Thorn Vines] swept away, two more rattans were involved in the No. 5 warehouse, and one after another long shadows were in the air, covering almost one-third of the entire warehouse area.

In the face of such a rapid offensive, Sun Yan and the three of them were caught off guard, quickly retreated, and in the blink of an eye, they retreated to the center of the warehouse, only to breathe a sigh of relief.

The three of them stood back to back, in the shape of a "product", guarding against the surrounding situation.

Lao Zheng spoke in a low voice, his speed of speech was extremely fast, and he explained all aspects of the characteristics of the [Iron Thorn Vine]: "[Iron Thorn Vine], a mutated sixth-level alien beast, is as difficult as an ordinary seventh-level alien beast. It is a terrifying creature with both vine and canine mammalian genes, its barbs are poisonous, and its venom is extremely corrosive. After this vine entangles its prey, its twisting force can exceed 1,000 tons, which is extremely terrifying. You must be careful not to get entangled in these vines. ”

Hearing this, Sun Yan frowned, if it was just to deal with the 5 rattans in front of him, it would be nothing. However, the purpose of their trip must be to pass through the central control room outside the warehouse, which is now intertwined with a web of [Iron Thorn Vines], and it may be quite difficult to pass through it safely.

Taking a deep breath, Sun Yan hugged Yuan Yuan with his left hand, his steps were staggered, his figure flashed, and he ran straight out, [Optimus One Pillar Gong] was activated, Yuan Li poured into his whole body, his right fist was clenched, and the orange light continued to flicker, facing a giant vine.

Boom!

This punch smashed firmly on the side of this giant vine, and the Yuan Force containing the Burning Sun fist intent poured into the rattan, raging and stirring wildly in it, and the fist of the Yang burst inside the rattan.

The next moment, the giant vine seemed to have received a fatal blow, and the half-meter-thick rattan withered and shrunk, showing a charred black color, and fell to the ground with a crackle.

Falling lightly to the ground, Sun Yan couldn't help but be overjoyed when he saw this scene, and Yuan Yuan in his arms also called out in surprise. Taking a step forward, Sun Yan wanted to make up for it with a punch and completely destroy this [Iron Thorn Vine], but Lao Zheng's anxious voice came from his ears: "Xiao Yan, be careful, don't get close, retreat!"

Hearing this, Sun Yan's heart suddenly appeared with alarm, and his body instinctively drifted backwards. I saw that the charred rattan on the ground suddenly swelled again, returned to its original state, and was erected into a javelin, piercing straight through the place where Sun Yan was standing just now.

"Damn, you were playing dead just now! Is this still a fucking vine? The fox is not as cunning as it is. Sun Yan was taken aback.

Next to him, Lao Zheng said quickly: "Be careful, [Iron Thorn Vine] is extremely cunning, once it finds that the prey is very threatening, it will show weakness and camouflage, and give a fatal blow when the prey is careless." In order to completely destroy the Iron Thorn Vine, you must find its roots and burn them with a scorching flame. ”

Sun Yan raised a middle finger and despised fiercely: "Lao Zheng, you did it on purpose, why don't you finish these words at once." ”

"Can I be blamed for this? It's rare that I can remember in such detail in such a situation. Lao Zheng's tone was a little aggrieved.

While they were talking, a rumbling explosion came, and the two hurriedly turned their heads to look, and their expressions were suddenly sluggish.
