The light was a bit dim. Jiang Zuiyao was afraid of falling, so she walked slowly while holding on to the wall. As she walked, she replied: "Don't worry about how I know it. The doors that can be opened with keys in this place are all unimportant places. The important places are all

It requires fingerprint or door card permission. Without permission, you can't open the door with your swords and sticks."

Jiang Zuiyao was right. In order to enter the fourth floor, the Taixuan tribe called martial arts masters to violently open the door but they did not open it. Little did they know that it was a high-strength equipment that was bulletproof and explosion-proof. How could they open it with the ideas of ancient people like them.

Oh, that's not right either.

Don't underestimate these ancient people. If you use force to open the door, it's not that you can't open the door. It's just that if you violently dismantle the door, the building will automatically turn on the self-destruct mode. A power outage is basic. Some confidential things on the upper floors will lock themselves.

, For example: the doors on each floor cannot be opened even if they have permission. People inside cannot get out, and people outside cannot get in.

Therefore, the Taixuan clan did not dare to act rashly, which was theoretically correct.

When we reached the third underground floor, every step we took was filled with dust and dirt. It was very dark. When we stepped on the ground, it made a "sand" sound. We could clearly feel the sand on the ground. The walls were also covered with dust. Jiang Zuiyao brushed the walls.

There will be fingerprints left, and the hands will be blackened by dust.

It seems that no one has been here for a long time.

Walking to the door of a room, Jiang Zuiyao turned around and said to Zong Yuan: "There should be a key in your key that can open this door."

Zong Yuan stepped forward. He was no longer as skilled as he was in picking out the keys to open the doors on the first, second and third floors. He started to try them one by one, and several keys could not be inserted into the keyhole at all, until finally he got one.

A key was inserted smoothly, and he tried to twist it left and right, but did not dare to use too much force.

Jiang Zuiyao couldn't wait any longer, so she stepped forward and grabbed the key, turned it to the right and opened it.

Zong Yuan asked curiously: "How did you do it?"

Jiang Zuiyao replied: "No one has come to this place for a long time, so the lock is naturally rusty. You can't open it without using force."

Zong Yuan took out the key and said: "I broke the key."

Jiang Zuiyao chuckled and said, "Don't worry, even if it's broken, you can still get in if you break it open."

Zong Yuan frowned for a moment and said, "Didn't you say that violence is useless?"

Jiang Zuiyao said helplessly: "It's useless to use violence on the upper door, but this kind of door is okay."

Entering the house, there is a surveillance room. There are five or six computers in the room of dozens of square meters, and there are several large screens hanging on the walls.

Zong Yuan asked again: "What are these?"

Jiang Zuiyao replied: "These are surveillance screens, used to check every corner of the building."

These are all irrelevant. Jiang Zuiyao pointed to the door in the room and said: "Open that door."

Only then did Zong Yuan realize that there was a door in the house. For him, this was the first time he came to this place, and everything was new, as if he was exploring.

In the same way, Zong Yuan began to try the keys again and again. When the door was opened, Jiang Zuiyao walked in. The inside was wider than the outer room. There were several large motors, which were taller than people. Zong Yuan looked at the four things in front of him.

The square motor feels very rare.

The man holding the torch curiously moved the torch closer to the motor to see that there were some buttons that they could not understand, as well as colorful wires. He curiously raised his hand and touched the wires. This kind of plastic insulated wire.

The material was something he had never seen before.

"Be careful!" Jiang Zuiyao reminded: "Don't get too close to the torch. If it burns out, it will be destroyed. If something like this is broken, it can't be repaired here."

A reminder, the person holding the torch was so frightened that he quickly retracted his hand and stood nervously, not knowing what to do.

Zong Yuan ordered: "Give her the torch."

The obedient man handed the torch to Jiang Zuiyao. Jiang Zuiyao took the torch and started taking photos everywhere, as if looking for something.

Except for Jiang Zuiyao, everyone stood at the door and did not dare to act rashly. They all looked at Jiang Zuiyao, as if they were a group of children who didn't understand anything.

After wasting a long time, Jiang Zuiyao found the device to activate the power-on equipment. After studying for a while, when the power-on prompt sounded, she was finally done.

Jiang Zuiyao stood up tiredly, her waist was a little sore from fatigue, she breathed a sigh of relief and said, "Okay, let's go."

A group of people followed Jiang Zuiyao back to the fourth floor obediently. After walking up and down the stairs twice, and having been squatting and tinkering for so long just now, Jiang Zuiyao was already very tired, holding up the torch.

I found a chair and pulled it over and sat down.

Zong Yuan asked curiously: "What should we do next?"

The torch was roasting people. Jiang Zuiyao handed the torch to Zong Yuan and said: "There is no hurry, we have to wait for the power equipment to operate for a while."

"Oh." Zong Yuan responded and took the torch obediently. In fact, he didn't understand what Jiang Zuiyao said at all. He had never heard such words in his life, but he didn't ask. He knew how to ask.

It's useless.

After waiting for almost an hour, many people could no longer stand. Some people were sitting on chairs, some were sitting on chairs, and some were sitting on the ground.

When Jiang Zuiyao felt that it had been long enough, she stood up and started looking for something. Zong Yuan immediately came with a torch to illuminate her until she found the switch. The moment she pressed the switch, the lights on the fourth floor came on instantly.

.

In an instant, the whole room was bright and clear, and the darkness that was previously unclear was now fully visible.

Under the illumination of the light, Jiang Zuiyao could see the appearance of everyone clearly. Under the dust and dirt, everyone's clothes were dirty. When she looked at herself, she was even more embarrassed. Her hands were so black that she couldn't see them.

His skin and clothes were covered in dust.

Looking at it again, it was even more dirty. There was a thick layer of dust on the table, chairs and the floor. It seemed that it had not been cleaned for many years.

Everyone looked at the things they had never seen before with surprise and confusion. Only Dieyi was okay. He had seen all these things. He took out the handkerchief and wiped his hands, handed it to Jiang Zuiyao and said, "You can wipe it too."

."

Jiang Zuiyao took the handkerchief and wiped her hands, but found that she couldn't wipe them clean at all, so she simply stopped wiping them.

Zong Yuan pointed to the glowing thing above his head and asked, "What is that?"

Jiang Zuiyao glanced at it and replied, "It's a lamp."

"Lamp? Don't you need fire?" Zong Yuan asked confused.

Jiang Zuiyao explained: "When there is electricity, there is no need for a fire. There are solar panels on the top terrace of this place, which can generate electricity."

Seeing Zong Yuan's incomprehensible look, Jiang Zuiyao thought to herself that Shao Ziqing was like this back then, asking her endless boring questions. If Shao Ziqing was here, she could explain to him what electronics is.

Already.

Thinking of this, Jiang Zuiyao shook her head vigorously, why should she think of him? She didn't want to think of him!

Zong Yuan saw Jiang Zuiyao minding her own business and suddenly shook her head and asked, "What's wrong with you?"
