Yang Dongqing took the thing in Duan Yuqing's hand and looked at it carefully, and saw that it was an oval, thumb-sized transparent crystal. This thing is crystal clear and transparent, smooth to the touch, and has a faint layer of water vapor on the surface, which looks very beautiful.

"Xiangyue said how to use this thing?" Yang Dongqing asked, if it weren't for the fact that this thing was transparent, he would think that it was an interstellar plant seed.

She walked in a hurry and didn't elaborate. Duan Yuqing shook her head.

Yang Dongqing nodded and put this thing away. Now, even if he knew that there was an enemy in the shadows, he had no choice but to be vigilant. Xiangyue was also powerless there, and he didn't know where the other party had gone. The only clue is the black market network he analyzed.

"The black market has always been very secretive, and there are many things that they promote....... Professor Li Hansen also asked me to help him investigate the black market after I was promoted to level six. Yang Dongqing thought of the conversation he had with Professor Li when he was on Noah's spaceship.

"Let's go down!" Duan Yuqing stopped and pointed to the entrance to the second floor. It was a mess, and the entrance had been enlarged several times, as if it had been expanded by a large cutting machine.

"This was done when Pop rushed out. Duan Yuqing continued.

Yang Dongqing looked at the entrance and was secretly speechless, from the first floor to the second floor with a thickness of more than twenty meters, the hovering actually drilled up, breaking the surrounding metal hard, how much power can this do.

Descending to the second floor, the first thing Yang Dongqing saw was the stilted mechas, all of which were blown down by the surging air currents that swirled out. Then he saw the huge entrance five meters square.

"Yangzi, you said that the snapping is so powerful, you have destroyed the passage from the first floor to the second floor, how can you be locked up on the third floor all the time and can't get out. Zhou Ziluo asked.

"yes, it should not be possible to stop it through the three-story door. Duan Yuqing, Rose, Lan Fei and the others nodded one after another. Zhou Ziluo said that they also felt strange.

"I don't know, let's go down and have a look. Yang Dongqing shook his head, came to the entrance and looked down, and saw that there were stairs leading to the bottom.

A group of people made their way down the steps, everyone cautious. The thickness between the second and third floors is about the same as that between the first and second floors, and it is less than thirty meters, and soon they reach the bottom.

However, as soon as they looked up, they exclaimed in unison: "How can this be?"

They saw the empty hall, and there was nothing but the surrounding walls.

"The third floor is empty, how is this possible?" Duan Yuqing shook his head in disbelief, the energy required for the operation of the base and the energy required for the defense system are all on the third floor, which is marked on the structure diagram. But how is the hall empty?

"The third floor is very large, and it is all over the cliff mountain, and the energy may be elsewhere. Yang Dongqing said.

"Yes, yes!" Duan Yuqing nodded in agreement, then took out the intercom and called up the structure diagram.

"Let's follow the structure diagram and look elsewhere. The diagram shows nine areas on the three layers. Duan Yuqing said, and walked away.

Yang Dongqing and the others then followed, striding towards the depths of the third layer......

"It's strange, how can the third floor be so weird. "After seven or eight minutes, everybody sensed something was wrong. There are no rooms on the third floor, they are all passages, so clean that there is not even a slag, let alone energy.

"It's all passages here, and the structure diagram clearly indicates energy. Lan Fei said with a frown.

"Pa Da has always lived on the third floor, does it never eat or drink?" Zhou Ziluo shook his head in confusion.

Yang Dongqing said: "The passage here is very strange, tortuous, chaotic, like a labyrinth, but it will not be chaotic. ”

"yes, it seems that it makes sense to go any way. Zhou Hao took over the conversation.

Duan Yuqing thought for a while and said: "According to the structural diagram, there is the control center of the third floor not far ahead, let's go there and see what I find." ”

After a few more minutes, they saw a half-human-high, square metal platform at the junction of the three passages, which looked so simple that it didn't even have a screen.

"This is the console, why doesn't there even have a screen?" Duan Yuqing walked over in two steps, looking up and down carefully around the platform, but there was no place to start.

Lan Fei and Zhou Ziluo also followed, but they also found nothing, this platform was like a whole piece of metal, without a single gap.

"It's a quadrangular prism, it's not a console at all!" Lan Fei shook his head.

"Let me try!" Yang Dongqing walked over and put his hand on the console. On the surface, this console is tightly fitted, but it may be discovered by using Qi to probe. That's what his Storm Gun is.

With his hand on the platform, Yang Dongqing used a big silk wrap and released his energy.

But then, he was stunned and whispered. He felt that the internal energy he had released was actually blocked. It felt like ...... It's like the protective energy carried by the gate of the Great Departure Dynasty's underground world.

"Protective energy, this base, and the one in the underworld, are also war fortresses. It's just that...... What's the connection between them?" Yang Dongqing hesitated for a moment, and his energy continued to be released, spreading down the console.

Then he made an even more surprising discovery. The floor of the passage also has that feeling of being blocked. In other words, the ground is also protected by energy.

"What's going on?" Yang Dongqing let go of his hand and lowered his head in thought.

Duan Yuqing, Zhou Ziluo, Lan Fei and others all looked at him. No one spoke, for fear of disturbing him.

After a moment, Yang Dongqing suddenly came to the side of the passage and put his hand on the wall. Just as he expected, defensive energy could be felt on the walls.

"Yangzi, what are you doing?" Zhou Ziluo couldn't help but ask.

"There's defensive energy all over the channel, all over the place. Yang Dongqing said.

"Defensive energy, what is it?" Rose came to the edge of the passage and learned Yang Dongqing to put her hand on the wall.

But after a while, Rose shook her head and put her hand down, and she couldn't feel anything.

"Master, I don't feel anything. Rose said.

"When you practice your strength, you'll feel it. Yang Dongqing explained, returned to the console, and put his hand up again. Since the console has energy protection, you may be able to open the console by finding the location without protection through the qi.

This time, Yang Dongqing was extremely meticulous, and the big silk controlled his energy and probed down around the console little by little.

Finally, when he reached the middle of the back, Yang Dongqing found that there was a very small area without energy defense. Then he turned to the back and pointed at the spot.

"Huh~" A holographic screen popped up.
