In fact, it is not that it is impossible to use this shelter for a long time, but it is very difficult.

First, the shelter is in the depths surrounded by swampy forests, except for masters above the sixth level of the Force Master, who can fly directly over, and it is extremely difficult for those below the sixth level to enter and exit.

Second, maintaining the normal operation of such a large shelter, even if only partially, requires a lot of energy.

At present, the shelter uses reserve energy from thousands of years ago, I don't know if it was built in a hurry at that time, or for some reason, the shelter does not have many energy reserves, and once these reserve energy resources are exhausted, the shelter can only be completely abandoned.

The energy supply system of the old era is completely different from the current one, and if you want to ensure the normal operation of the shelter, you must find a way to find the reserve energy left by the old era.

This item is very scarce right now, and the Purification Sect doesn't have much in stock. And they have to be supplied first, and their own base operation will definitely not be taken out and used by a new shelter that is not of much value.

In addition, it is necessary to build a new energy supply system. This is a huge and incomparably large project. With the strength of the Purification Sect, it is impossible to build another energy supply system for this shelter in the short term.

Therefore, it is most cost-effective to empty the shelter as much as possible. In the end, Yalan proposed to copy a copy of the information stored by the supercomputer, and Zhou Ziheng agreed, and offered to ask for a copy himself.

At that time, Wang Xiaotian saw that Zhou Ziheng asked for half of the machine tool, and he felt a little incomprehensible.

Because this kind of machine tool is very complicated to operate, even if it is a mechanic before the old era, it needs to go through a long training period before it can be operated. It's not just a matter of looking at it twice and learning how to use it.

In addition, the operation of these machine tools, which is highly dependent on electrical energy, leaves this base, and is basically scrap metal.

Moreover, the data stored by those supercomputers can only be used on the supercomputer, and there is no other way to open it.

What did Zhou Ziheng want to do with this? But some things that happened later made Wang Xiaotian understand, what is called scheming.

Arlan is copying the data from the supercomputer. The large screen is back to the monitoring state.

Wang Xiaotian looked at the big screen boredly, and suddenly let out an exclamation.

Everyone looked sideways.

Wang Xiaotian pointed to the big screen and said, "Someone got down from that long elevator." ”

Yalan immediately called up the surveillance screen to zoom in. The picture shows a young man with long flowing hair, wearing a jacket full of rivets, with his hands in his jacket pockets, his shoulders drooping, and he looks lazy.

What's even stranger is that there is a big black dog at his feet, and a small monkey, riding on the dog's back.

Wang Xiaotian was very happy, the black dog and the little monkey did not run away. He was still thinking about how to find them when he got out of the shelter in a while.

But what made him even more strange was how Yu Wanlai found here?

So, he turned his gaze to Zhou Ziheng. Could it be that Yu Wanlai is the backhand arranged by Zhou Ziheng?

When Master Hao saw the stranger coming in, he immediately asked Zhou Ziheng, "Your Excellency, do you want to ......?"

Zhou Ziheng said: "Don't worry. Own. You arrange for people...... Forget it, little tree, you take a trip. If you don't trust strangers, don't make a misunderstanding. ”

Shen Shuming nodded, turned around and left.

Zhou Ziheng looked at the screen and asked Wang Xiaotian, "How did this dog meet Yu Wanlai?"

Wang Xiaotian shook his head, "I don't know either." Just now in the passage, I and I were separated from the dog. ”

In fact, the black dog and the little monkey were really unexpected when they met Yu Wanlai.

In the cave where Ming'an's body was located, the black dog waited patiently until after Wan Lai left. It couldn't figure out why Yu Wanlai appeared here, and he muttered to Mingxin for a long time.

It was a little scared in its heart, afraid that it would be killed by Yu Wanlai.

As the saying goes, "what you're afraid of comes". There was only one way to leave, and the black dog turned around and turned to the cave in the lair of the Earth Walking Dragon, and then it ran into Yu Wanlai.

In this hole, Yu Wanlai clearly felt that the strong Force conflict had not dissipated for a long time.

He could tell that one of the very powerful forces was Zhou Ziheng's, and the other one should be the Earth Walking Dragon.

Yu Wanlai also saw that there were several large pools of blood on the ground. He walked over and crouched down beside a pool of blood, and found that it had not yet dried.

He reached out and dipped his fingertips in a little blood, put it on the tip of his nose and sniffed it, and immediately recognized that it was not human blood.

He deduced from the traces of the fight in the cave and the number of blood stains on the ground that this should be the final battlefield between Zhou Ziheng and the terrain dragon.

However, apart from a few large pools of earthly dragon blood, there were not too many other traces of human blood on the ground. It can be seen that Zhou Ziheng did not have a conflict with the people of the Purification Sect.

But where so many people went? He got up and looked around, and soon noticed something strange about the wall.

He was about to walk over when he suddenly noticed a dark shadow at the entrance of the cave.

Yu Wanlai immediately looked intently and saw the black dog carrying the little monkey at the entrance of the cave. The black dog seemed to have just come over and was very surprised to see him.

In fact, the black dog didn't want to run into Yu Wanlai at all. It was not familiar with Yu Wanlai, especially after seeing Yu Wanlai's words and deeds in that cave just now, it became instinctively wary of Wanlai.

It felt that Yu Wanlai appeared secretly, and muttered to the man in the black robe for a long time, and he must have done nothing good.

However, Yu Wanlai is very strong, so strong that he can poke it to death with one finger. Now that it has met Yu Wanlai, it can't run, let alone show fear and hesitation.

Once it exhibits abnormality, Yu Wanlai will definitely poke it to death without hesitation. Seeing that Yu Wanlai had discovered himself, the black dog clearly felt that danger was imminent.

What should I do?

In fact, Yu Wanlai is also wondering now, what's wrong with this stupid dog? Why did he see that I didn't come? Is it because he didn't know me well? He and Wang Xiaotian hadn't been in contact for a long time, and they weren't too familiar with this dog, so they had this guess.

After a fierce inner struggle, the black dog decided to fight it out and see if he could get through.

So, it immediately trotted all the way over, circling around Yu Wanlai's legs, and waged its tail like a windmill.

How did Yu Wanlai know that the thoughts in the dog's heart disappeared when he saw the dog running over. He bent down and rubbed the black dog's head with a grin, "Why aren't you with your master? Are you separated? It's okay, follow me and I'll find them soon." ”

With that, Yu Wanlai got up and came to the mountain wall.

The Purification Sect's man, the mountain wall that was cleared out was very obvious, he reached out and grabbed the depression and pulled it, and then he saw the keyboard and screen inside, and then heard the prompt sound of "Please enter the password".

Although Yu Wanlai saw this thing for the first time, he had used the current Liujia combination lock, so he knew that this was the combination lock of the old era.

It's just that he doesn't know the password at all, how to enter it?

He frowned and thought for a long time, and suddenly a flash of inspiration flashed in his mind.

Normal people have sebum on their hands, as long as they don't wear gloves when entering the password, the sebum will stick to the keys!

Yu Wanlai immediately reached out to activate the Force, and a piece of gravel flew into the palm of his hand. He turned his palms lightly, and the small pebbles in his palms were twisted into stone powder, and then he attached a faint trace of force to the stone powder, and his palms were lightly extended, and he hugged them into a ball, and the stone powder was pulled by the force, forming a cloud of mist.

He lured the stone powder mist to the top of the keyboard and manipulated the stone dust to sprinkle on the keyboard.

The stone powder has a very weak force attached to it, and it is easily adsorbed by sebum.

Then, with a gentle wave of his hand, he blew away the unabsorbed stone dust.

Yu Wanlai bent over, lowered his head and observed carefully, and found that 1, 2, 4, 6, 8, and 9, six buttons, left a faint stone powder.

Then the password should be, made up of these six numbers.

But what is the order of the passwords?

There are dozens of combinations of these six numbers, which one exactly?

Yu Wanlai knew that there must be a limit to the number of times the password can be entered, and it will definitely not work if you try it one by one.

He stared at the six numbers, and his brain began to run at full speed.

The amount of sebum on the fingers is limited, and the sebum will be a little more on the button pressed first, and it is mainly concentrated in the middle of the button. When you press the button later, there will be less and less sebum sticking to it, and it will be mainly concentrated around.

Thinking about this, Yu Wanlai was very happy.

Yu Wanlai took a closer look and found that on the three keys of 2, 4 and 6, there was more stone powder, followed by the 8 button, and the 1 and 9 buttons were very few, so I couldn't see the difference.

Taken together, the possible passwords are narrowed down to two: 246819 or 246891.

Choose one of the two. Yu Wanlai didn't know which one to choose, so he could only hit the luck.

He typed in the 246891 and then stared nervously at the screen, only to hear a prompt that said "Wrong password, please re-enter."

When Yu Wanlai heard the hint of the wrong password, his mood became extremely depressed. Because of the Rokko combination lock, as long as you enter it once, the password will be reset.

In other words, even if you enter the correct password the second time, it won't work. When he heard the "please re-enter" at the end, his heart suddenly rejoiced.

He hurriedly typed 246819 again, then stared nervously at the small blue screen.

"The password was entered correctly. The start-up process will be a bit long, so please be patient. When Yu Wanlai heard this prompt sound, his hanging heart was gently relaxed.

After a while, there was a "creaking" sound. Yu Wanlai looked at the two huge gates, which slowly opened in front of him, and couldn't close his mouth in surprise.

After a long while, Yu Wanlai came back to his senses and walked inside, looking left and right as he walked. The black dog drooped his tail and shook his head and followed Yu Wanlai.

When he walked to the second gate, Yu Wanlai's mood had calmed down from the initial surprise.

It's still taking medicine according to the prescription. After some tossing, Yu Wanlai and a dog and a monkey finally opened the door and entered the elevator.

Waiting for the elevator to stop, Yu Wanlai took a dog and a monkey and walked out of the elevator door to the observation deck. He glanced down at the scene below and was immediately shocked.

He didn't expect that in this cave hundreds of meters underground, there would be such a huge building complex!

Where is this cave, this is an underground city at all!

The people left behind by the Purification Sect are scattered among the buildings in the city, using various instruments, carefully mapping these buildings, and occasionally randomly entering the room to search to see if they can find anything valuable.

When they saw Yu Wanlai appear on the observation platform, the Purification Sect members immediately became alert, and after a brief exchange, they quickly put down their work and rushed to the nearest elevator, preparing to converge on the observation platform to meet Yu Wanlai.

Soon the people of the Purification Sect, in twos and threes, gathered from the long corridor, like a trickle of water into a river.

They gathered in a group and slowly forced towards Yu Wanlai.

Yu Wanlai didn't take these small shrimps seriously. He is the best at group attacks, and none of these people can block his attacks, and he can kill them with a single hand.

Moreover, for him, these people will be killed if they are killed, and psychologically they will not be at all, and there is no obstacle.

Just as Yu Wanlai was whistling and facing the Purification Sect, he pulled out the hand in his pocket and was about to start killing, when he suddenly heard a crisp sound of "ding", and the elevator door behind him suddenly opened, and someone walked out quietly.

Yu Wanlai's heart sank. Although the person who came was very light, he sensed that this person's strength was by no means below him.

If it's someone from the Purification Sect, it's definitely a hard idea.

However, the other party did not show killing intent, and Yu Wanlai did not dodge immediately, but remained highly vigilant and slowly turned his head so that his body did not show any flaws.

It is equivalent to Wan Lai looking back, and suddenly secretly relieved, and said with a smile: "It's hairy, it almost scared me out." ”
