Master Obscurity immediately stopped and nodded to Arran.

Yalan raised his hand and waved lightly, and immediately four people wearing white robes, white hats, large white masks on their faces, and shovels, knives and other tools in their hands walked out quickly. One of them was carrying a black iron box.

The four of them came to the place where the long staff made a crunching sound, and used knives and shovels to clean the moss from the mountain wall with their hands and feet.

When knives and shovels come into contact with the wall, there is a sound of metal scraping.

Everyone couldn't help but wonder, could it be that the entire mountain wall was made of metal?

When the moss hung up, the silver-gray mountain wall was revealed, and sure enough, it was made of metal!

Wang Xiaotian couldn't help but be stunned when he saw it, what a big deal this is?

Master Obscure sighed: "These mountain walls have lasted for thousands of years, and there is no trace of rust in the humid air, and this metal has such a strong ability to resist corrosion! ”

Arlan nodded slightly, "Compared to the highly developed technology of the Old Era, our current technological level is only a limited strength compared to theirs in the Steam Age. ”

The four of them quickly cleared out, an area of about one square meter. In the center of this place, there is a depression that just holds the palm of a hand.

A white-robed man reached out to clasp the depression, and with a slight pull, a large piece of the mountain wall was pulled apart, revealing a hole inside, half a meter wide and half a meter high.

There is a 45-degree inclined one in the cave, which is engraved with 0, 1, 2...... The 10-digit buttons up to 9 are engraved with the words "confirm" and "clear" on two buttons. On the top of the keyboard, there is a palm-sized blue screen. Next to the screen, there is a switch button.

Yalan looked over, breathed a sigh of relief, looked back at Master Obscurity, and said, "It's a general-purpose combination lock." ”

Master Obscure also breathed a sigh of relief and said, "Let's start decoding." ”

Aran beckoned to the white-robed man with the black box on his back. The man came to Arran, removed the black box from his back, and held it in his hand.

Yalan opened the box, pulled out two wires from it, inserted them into the two holes under the keyboard, and then turned on the switch of the device in the black box first.

The device in the black box is very simple, just a small green strip-shaped screen, a switch and two buttons, one under which is written to start, and the other to clear.

After Yalan pressed the switch, the machine made a crisp dripping sound, and the green long screen lit up one by one from left to right. Each small screen is no more than two centimeters wide and only about two and a half centimeters high.

When all six screens lit up, Yalan turned on the switch next to the blue screen in the recess of the mountain wall.

After the switch was turned on, Wang Xiaotian heard a low buzzing sound, like a sleeping giant beast, and began to wake up.

He looked around nervously, but didn't notice anything out of the ordinary. At this time, he found that he was not the only one, Zhou Ziheng and the others, as well as most of the people in the Purification Sect, were looking around. Except for the four hall masters of Yalan, as well as the white-robed man, he seemed calm and composed.

Wang Xiaotian secretly thought that the fear of the unknown is human nature. These are as nervous as themselves, and they should be the first time to see and open the shelter. Those who are calm and composed, of course, are not the first time.

After about ten seconds, the blue screen lit up, and a pleasant female voice came out, "Please enter the password." ”

What the hell?

At this time, Arlan pressed the start button of the machine in the black box. On the first green screen on the left, the numbers begin to change rapidly, and soon they are locked on 2. The numbers on the second screen on the left also began to change rapidly.

When the black box began to decode, a pattern appeared on the blue screen. It's a simple diagram of "please enter password", which is one hand pressing back and forth on the keyboard.

At the same time, a pleasant female voice said: "Please enter the password within one minute, otherwise the system will be locked and cannot be turned on again within 48 hours." If you enter the wrong password three times, the system will also lock it for 48 hours. Please enter the secret as soon as possible. ”

Then on the blue screen, two changing white numbers "45, 44, 43......" appeared

Yalan looked at the second number 4 that appeared on the small green screen, and said lightly: "One minute is enough." The opening of this shelter is not too difficult. Compared to the previous shelter, it was simply relaxed and pleasant. ”

Zhou Ziheng pointed to the black box and asked Master Hao curiously, "This is the key you are talking about?"

Master Obscurity nodded, "Yes. This black box is the key to the shelter. It's called Password Cracker. Originally, the company that built the shelter was left behind in order to prevent accidental locking of the system. We were lucky enough to get it. ”

"These shelters were built thousands of years ago, and the codes they set are long since no one knows them, and they can only be cracked by force with a cracker. Fortunately, the passwords of the gate are relatively simple, and they cannot be compared with the Rokko combination lock used now. ”

In fact, he still didn't say a word, that is, the password of the core area of the shelter is very complicated, and the difficulty of cracking is very high, and it is definitely not something that can be completed in a moment. And the really valuable things are almost all in the core area.

The third and fourth digits on the small green screen are locked, 6 and 8, while the numbers on the blue screen are only 32. At this rate, the numbers on the blue screen will reach about 20, and all six digits of the password can be cracked.

Zhou Ziheng asked again: "If there is enough time, can it be turned on after many attempts?"

Master Obscure didn't speak. Because this question seems to him to be low.

Arran explained: "Theoretically. But it's actually hard. The six-digit password is composed of numbers, and the total number of combinations that can be generated is as high as 1 million. 3 attempts per attempt, 48 hours locked, and it takes 66,667 days to try them all once. ”

"If you're lucky, and you can find the correct password about halfway through the attempt, it will take more than 30,000 days. In other words, if you are willing to spend a lifetime, you can almost open a shelter. In reality, no one wants to do this, it's too much to lose. ”

Zhou Ziheng nodded thoughtfully.

At this time, on the small green screen, the last two numbers also came out 1 and 9. Yalan immediately entered the six-digit password on the keyboard 246819.

A pleasant female voice rang out again, "The password is entered correctly." The start-up process will be a bit long, so please be patient. ”

Then, ten seconds passed, twenty seconds passed...... A minute passed, and the mountain wall still didn't respond.

Zhou Ziheng said: "It's a little too long, isn't it?

Master Obscurity looked a little uneasy, and said, "Wait." After all, it has been useless for more than a thousand years, and it is inevitable that some equipment will fail. And if the shelter is larger, the energy system starts more slowly. I don't think this shelter is small, so let's wait. ”

Two minutes passed, and everyone became restless, and the people of the Purification Sect had already begun to talk to each other.

Three minutes passed, and even Yalan, who had always been very calm, showed an impatient look on his face.

Master Obscurity wanted to advise Yalan to turn off the system and turn it back on, but when he thought that once it was restarted, it might take 48 hours to turn it on again, so he held back.

Guo Ding has already begun to be eager to try, wanting to try two punches against the mountain wall.

Four minutes passed, and just when everyone was eager to try and greet the mountain wall with their fists, suddenly an unusually loud and low "buzzing" sound came, which shocked everyone's hearts, as if they had been punched in the heart, and their heartbeats missed a beat.

Yalan said excitedly: "It's activated." ”

At this time, the mountain wall began to shake, and countless moss and stone chips fell down like rain.

Everyone hurriedly retreated to a distance of five meters, waving their hands to fan away the dust, while staring nervously at the mountain wall.

After a long, tooth-aching, piercing sound of metal grinding, a crack finally cracked in the shaking mountain wall.

Looking at the dark entrance of the cave, everyone couldn't help but wonder, will there be a monster popping out of it?

In fact, there are no monsters popping out at all. The mountain wall continued to crack until the crack was four or five meters wide.

The height of the mountain wall is more than seven meters. At this size, even heavy trucks can drive in.

Looking at the huge black hole, everyone is thinking about whether to make a torch or something like that to illuminate.

At this time, there was a "bang" sound, and the inside of the black hole lit up one after another, and a huge lamp illuminated it as if it were day.

Seeing the wide cave, everyone let out an exclamation. Zhou Ziheng couldn't help but wonder, what kind of method did the people of the old era use to dig such a spacious cave on the hard mountain wall?

Master Obscure's expression relaxed, and he said with a smile: "I didn't expect that the power supply system in this shelter would be intact, but it saved us a lot of trouble." ”

Zhou Ziheng said: "You have encountered a shelter where the power supply system is broken before. ”

Master Obscurity nodded, "These shelters have been useless for more than a thousand years, and they are only normal if they are faulty, and there are actually very few that are not faulty. The door is open, Your Excellency, please. ”

Zhou Ziheng said: "You please first, we will break later." ”

Seeing Zhou Ziheng's clear attitude, he didn't want to be used as a gunman by them, and Master Hao Zhi didn't give in hypocritically, and said, "Then we're welcome." ”

As he spoke, Master Obscure waved his hand at the Purification Sect. Guo Ding led the hunters of the Wind Hall to enter the passage first, followed by the technicians of Yalan and Tanwei Hall, and then the master and apprentice of the Bamboo Dao people.

Then, Master Hao raised his palm with one hand, saluted Zhou Ziheng, and said, "The poor monk takes the first step." "Turn around and enter the passageway.

When all the people of the Purification Sect entered, Zhou Ziheng and the others entered the passage.

Shen Shuming held a crossbow arrow in his hand, walked to Zhou Ziheng's side, and asked quietly: "Why don't you kill them? With our strength, it is easy to destroy them completely." ”

Zhou Ziheng stopped, raised his hand to lay down a soundproof barrier, and prevented the Purification Sect people in front of him from eavesdropping. Then he said, "What's the use of killing them? If you work with them, you have a lot to gain. ”

Shen Shuming looked at Zhou Ziheng with some surprise, "Didn't you hate compromise and exchange of interests the most in the past? ”

Zhou Ziheng sighed and said, "When everyone grows up, they will become the one they hate the most." When I was young, I had to compromise with reality. ”

"Cut. Shen Shuming said disdainfully: "Don't pretend to be middle-aged with me here." What the hell is going on?"

"Do you know what Dean Li did?"

"I only heard that he disappeared three years ago, and I really haven't heard anyone say what he did. ”

The Master of the Force has a long lifespan, and it is normal for him to retreat for three or five years at a time. Therefore, although Dean Li has been missing for three years, everyone is just talking about it privately. And until he gets the exact news of his death, he will not appoint a new dean.

Zhou Ziheng said: "He's not missing. Instead, since three years ago, he has found a safe place and started retreat to attack the eighth level and be promoted to the Force Grandmaster. ”

Shen Shuming gasped, "He's fighting for his life." In his condition, he didn't even have half the success rate of hitting level eight. ”

Zhou Ziheng sighed, "Who said it wasn't." ”

"What was the result?"

Zhou Ziheng shook his head lightly, "I don't know either." It's been more than three years, and there's not much news coming in. Therefore, I don't know if it has already begun to hit level eight. However, with his character, since he said it, he will definitely do it. In the end, whether it succeeds or not, we have to plan ahead. ”

Shen Shuming was puzzled, "What do you mean?"
