"Master Hou, let's set off quickly, the appointed time is almost up, let's not miss the auspicious time."

Seeing that Xu Rui had always been attracted by the equipment here, and stopped to watch for a long time, Xiao Hu couldn't help but urge.

Xu Rui came back to his senses and saw that Xiao Hu was already standing by the thick open door, so he nodded and walked towards him, but when he passed by Xiao Hu and was about to pass through the door first, he was slightly stunned.

The metal door shimmered with a unique sheen, and it was still new after an unknown amount of time, unlike any other metal in the cavern.

Xu Rui recognized at a glance that the door was made of an ultra-high-density alloy made from a raw material that could only be found on magnetars and required countless complex processes to make.

Magnetars are a type of neutron star, formed by supernova explosions, small in size but with terrifying density and gravitational pull, high speed rotation makes it have a strong magnetic field and high-energy electromagnetic radiation such as gamma rays, and is one of the most dangerous objects in the universe.

Humans approaching magnetars unprotected are likely to be broken down into atoms by their strong gravitational pull and magnetic field, making it difficult for even a sturdy Star Destroyer to escape.

One can imagine how much it would cost to mine minerals on magnetars.

However, this ultra-dense alloy is extremely strong, with a protective force that even planetary railguns cannot penetrate, and the property that it is difficult to oxidize over countless years.

As a result, this ultra-high-density alloy is often used in the strongest fortifications, or in the protection of the core components of spaceships.

And the outer layer of this metal door is actually made of this alloy, there is only one possibility, that is, behind this door, I am afraid that there is something hidden, at least once hidden, extremely terrible.

Thinking of this, Xu Rui was shocked, and when he turned his eyes, he suddenly found that a small screw only the thickness of chopsticks had fallen from his feet, the screw had a round head facing down, but the pointed tail stood up, obviously not falling naturally.

Xu Rui frowned, as if he had thought of something, and couldn't help but groan.

"What's wrong?"

Xiao Hu saw Xu Rui stop and asked puzzledly.

"Nothing."

Xu Rui's face instantly returned to calm and shook his head.

"Then let's go, it's too late."

Xiao Hu seemed to be a little anxious, and didn't dwell too much, just urged Xu Rui to continue on the road.

Xu Rui nodded and took a step towards the door.

At this moment, a trace of ecstasy flashed on Xiao Hu's face, and an extra ring similar to a bracelet appeared in his hand, pinched it hard, and then suddenly pressed it towards Xu Rui.

At this moment, Xu Rui's footsteps suddenly stopped, and the broken blade that was still in his hand before had come out of the sheath and slashed straight towards Xiaohu's throat.

If Xiao Hu doesn't take back the things in his hand, he will be blocked by Xu Rui's sword.

Xiao Hu was startled, his body folded back, and he suddenly bent into the shape of a bow, which was able to dodge Xu Rui's sword.

Under normal circumstances, Xu Rui's sword strength was exhausted, and he would definitely return to the sword and come out again, but the long sword suddenly turned in the air and continued to slash downward.

Xiao Hu's face changed slightly, his body loosened, and he fell to the ground in an instant, and then he turned over and flew up, kicked on the broken front, and flew back upside down with the force of the shock.

As soon as he landed, he didn't have time to rejoice, but suddenly found that Xu Rui in front of him had disappeared, and then the hairs on his back stood on end, and a sense of crisis arose.

Xiao Hu's heart tightened, he pulled out the long knife on his waist and slashed it back, this knife came out in a hurry, but with the power of thunder, there was a faint sound of wind and thunder, and the momentum was not far behind Xiao Jinwu and other martial saint heirs.

With a sound of "dang", the broken blade and the long knife struck each other, the long knife broke in response, and half of the blade flew out instantly, Xu Rui only felt that the tiger's mouth holding the sword was actually numb by a huge force, and the originally planned pursuit was instantly disintegrated.

Taking this opportunity, Xiao Hu immediately took two steps back, pulled out another short knife on his waist and confronted Xu Rui, his face was extremely solemn.

"In such a short period of time, your martial arts have broken through again?!"

Xiao Hu looked at Xu Rui and asked in shock.

Xu Rui sneered and said: "It turns out that you have hidden your strength, no wonder you have always been confident, but it's a pity that the current me is too far away from the original me, you think that I will be easily held by you, but you miscalculated!" ”

Xiaohu frowned: "How did you find out that I wanted to be against you?" ”

Xu Rui smiled: "From the beginning, I found that you were not quite right, I originally wanted to see what you were paying attention to, but now it seems that I am afraid that the opening of the door is fake, and it is true to trick me here, right?" ”

Xiao Hu was stunned: "I don't know where I showed my flaws?" ”

Xu Rui laughed and said: "If you want to say that there is only one flaw, it is that you are too stupid!" ”

"Too stupid?"

Xiao Hu was puzzled.

Xu Rui smiled and said: "There are many elites in the Ghost Valley, and the people born in each generation are not amazing, do you think you have anything to do with these words?" ”

Xiaohu frowned and did not speak.

Xu Rui continued: "You are too far from the level of the people born in the Ghost Valley, if it is not for the withering of this generation of people in the Ghost Valley, it is that you know how to hide the front and hide your true strength and purpose. ”

"So this is also a flaw......

Xiao Hu's pupils shrank, but he quickly regained his composure, and sneered: "Since you have already understood my plan, you should take me immediately, at least you shouldn't come here with me, blame you for being too confident, since you have come, then in the end I won!" ”

After speaking, he clapped his hands lightly, and a footstep immediately sounded in the passage behind Xu Rui.

"You think that the elites of the division are all in the cave, but you don't know that since the time we left the camp, someone has secretly followed us, even if you have improved your martial arts, you will never be able to escape from my palm!"

Xiao Hu laughed loudly, as if he had a chance to win.

However, when the footsteps came to the front and Xiao Hu saw the person's appearance clearly, the smile immediately froze on his face.

"I'm sorry, but I've already taken care of the waste you mentioned."

Standing behind Xu Rui, he said expressionlessly.

"It's you! How did you end up here?! ”

Xiao Hu came back to his senses and asked in horror.

Xu Rui smiled: "I have long seen that you are afraid of leaving, because you are afraid that the sudden appearance of such a master by my side will ruin your big thing, so before leaving, I was reminded several times to keep this matter secret, in order not to let me take it with you."

Seeing that you are acting so hard, of course I have to plan for him not to show up, just follow me from afar, so that there will be room for you to play to your heart's content! ”

Xiao Hu Wenyan's face finally turned blue, his two eyes rolled slightly in his sockets, and he suddenly turned around and wanted to run towards the heavy gate, but as soon as he turned around, a palm immediately pressed on his face.

Yaoli, who was obviously standing behind Xu Rui just now, appeared behind Xiao Hu in an instant and pressed him to the ground.

Not only that, the moment the hand that wanted to leave touched him, Xiao Hu was sore, as if all his strength was drained in an instant.

Xu Rui slowly walked to Xiao Hu's side, took the bracelet from his hand and took a closer look, a trace of surprise flashed on his face: "It turned out to be this thing that you were going to use against me?!" ”

As he spoke, a sneer flashed across his face, and he clasped the bracelet on Xiaohu's hand.

"No, don't!"

Xiao Hu looked frightened and shook his head.

But Xu Rui didn't have any pity on his face, he picked up the little beard with the bracelet on it, and pushed it into the thick door.

"Don't!"

Xiaohu screamed in horror, but there was no room for struggle.

The moment he entered the gate, the bracelet on his wrist seemed to be activated by something inside the gate, and the original metal turned into countless trickles, like a poisonous snake burrowing into his skin.

Immediately after that, countless light blue arcs suddenly jumped on Xiao Hu's body, and his body began to twitch wildly.

But in the blink of an eye, Xiao Hu rolled his eyes, and fell to the ground with green smoke on his body.

Looking at all this coldly, a trace of emotion flashed on his face.

"That bracelet is so magical, it's also a fairy thing?"

Xu Rui shook his head: "That bracelet is a torture tool used to control the genetically modified warriors after going berserk, but I don't know why it is in his hands." ”

I was confused by what I heard, but I was not interested in asking again, so I said lightly: "You owe me a favor again." ”

Xu Rui smiled: "Don't you want to know the truth of this world?" Hopefully, you'll be able to get what you want. ”

To be stunned for a moment, after seeing Xu Rui's martial arts advancing by leaps and bounds, he linked the hope of breaking through the bottleneck of the martial saint with the so-called world truth in Xu Rui's mouth.

Hearing Xu Rui say this at this moment, a trace of expectation suddenly arose in his heart to leave.
