"Let's go! I think I already know where we're going, and there's a gate in the middle of the passage that leads to the center of the complex, if I'm not mistaken!"

Through the news fed back by Shadow Snow, Yu Chen has concluded that there is no danger in this area, and immediately put his mind at ease and led everyone forward, the huge metal corridor like the Heavenly Palace, it is naturally extremely long to walk, and after walking for about half an hour, everyone saw the second huge gate 'gate', this gate 'gate' is exactly the same as the one Yu Chen they walked out of before, in the gate' There is a control switch on the side of the door, for this kind of switch, Lin Tianhua and the others are no longer unfamiliar, so Lin Tianhua took the initiative to open this gate 'door', and then everyone really found a huge space that was the same as the previous space.

"Let's go, our goal is not here!" Yu Chen said with a smile, and then continued to move forward with the others. After walking for about a meal again, on the other side of the hallway, a special sign finally appeared, and next to that sign there was a metal 'door' that was more normal than the giant gate.

"It should be here, right?" Chu 'Yu' asked as he looked at the silver-colored metal 'door' six or seven meters high in front of him. Yuchen nodded, looked at the screen similar to an electronic instrument next to the 'door', and couldn't help but say in his heart, finally it is no longer the original lever handle!

"Why don't there be buttons and handles?" Lin Tianhua couldn't help but ask after scanning around the 'door' without sending a handle or button.

"This 'door' is different from other 'doors'!" Yu Chen said with a smile, and started to walk in front of the screen similar to an electronic screen to observe carefully, but with the observation, Yu Chen's face 'color' gradually became difficult to see, because Yu Chen found that this electronic screen does not seem to have facilities such as entering passwords, that is to say, this screen should be a sensor, and from the height of this sensor located in the 'door', it should be a fingerprint or palm print sensor.

"What's wrong?" Zikong Bing couldn't help but ask when he saw Yu Chen's expression become solemn.

"I may have found a way to open this 'door'!" Yu Chen said.

"Then why do you have such an expression?" Chu 'Yu' said curiously. Yu Chen couldn't help but smile bitterly: "Because finding it is the same as not finding it! If I guess correctly, if you want to open this 'door', you need fingerprints or palm prints, and you can touch and 'touch' this thing in front of you!"

"That's not easy, I'll have it all!" Lin Tianhua laughed, and then put his handprint on it, this action made Yuchen speechless, your fingerprints or palm prints have not been stored in advance, it's strange that you can go in?

Just when Yuchen thought it was impossible, he saw four small red 'color' lights suddenly flashing at the four corners of the big 'door', and then he heard a crisp click, obviously the metal bolt in the 'door' collided, hearing this sound, Yuchen's eyes suddenly bulged, and then, the metal 'door' in front of him made a slight sound as if vaporizing This slowly shook for a while, and then slid to the sides.

"I'll go!" Yu Chen finally couldn't help but shout, what was going on? Lao Lin's palm print could actually open this 'door'......? This Nima is too messy, how can the palm prints completely coincide? The shock in Yu Chen's heart rose to the extreme at this moment, even more shocked than when he saw those energy crystals before, after all, this thing was too weird. However, Yuchen didn't know that this 'door' was actually not really entered into the palm print system by its original owner, because this 'door' was connected to an energy repository, and people often had to pass through here, so it was just set up with a simple static induction, that is, as long as someone put their palm up, the induction system sensed static electricity, and this 'door' would automatically open.

"Haha! I'm such a genius!" Lin Tianhua laughed. Dong Xuan, who was next to him, couldn't help but glance at him and said: "Shao Smelly Beauty, there must be something strange that made you open this 'door' by mistake!"

Yuchen glanced at the screen, his heart moved as if he wanted to hit something, and slowly stretched out his hand to put it on, after his hand touched the sensor screen, a slight vaporization sound came from the big 'door', and it slowly closed in Yuchen's original look.

"It's either that there is something 'wrong' with the induction system, or that there is no special 'door' to look at the palm print in the first place!" Yu Chen said with a smile. Then he opened the 'door' again and said, "Let's go!

Hearing Yu Chen's words, Zikong Bing and the others couldn't help but 'reveal' their extreme expectations, this is a shocking secret that has never appeared before!

Behind the 'door' was still a corridor, with many strange raised lines on the walls, and the corners of Yuchen's eyes 'revealed' a hint of expectation. "Technology", the word flashed in Yuchen's heart. If this is a collection of scientific and technological civilizations, if you can find some weapons that can make high-intensity and powerful weapons here, maybe the discovery here will really become the hope for dealing with the underground dead Zerg in the future, you know, the number of cultivators is too small, compared to the entire continent, or non-cultivators dominate, if you can condense all the cultivators into a force that can fight the Zerg, human beings may be able to survive this Zerg disaster!

Zikong Bing and the others naturally didn't know what Yu Chen was thinking, but their thoughts were the same as Yu Chen's thoughts, but their thoughts were much simpler, using those energy crystals outside, they would definitely double the strength of all the repairers, so that the human race might have a chance to resist, right?

"Roar~~" Just when Yuchen and the others were thinking about something, a huge roar suddenly came from the end of the corridor, which made Yuchen and the others startled, in this dead and silent underground world, how could there be creatures? If there may be some magical beasts in the space outside, there may be some magical beasts that have strayed into the 'cave', but where Yuchen and the others are at this time have passed through at least two gates! Could it be that those magical beasts have also moved to open these gates?

"Master, that thing is in front! It's approaching rapidly!" said the four-clawed shadow snow transmission, at this time the height of this passage is only a dozen meters, and the width is no more than twenty meters, and it can't allow the shadow snow to fly. As a result, Shadow Snow can only rely on its four claws to move forward on the ground. Because of the loss of the advantage of flying, the little guy can only wait for the other party to approach at this time, and cannot launch an active attack.

"Prepare for war!" Yu Chen shouted in a low voice, and then stepped out, there was already an extra silver 'color' heavy sword in his hand, Zhan Jiu and Lin Tianhua also took out their weapons coldly, standing on both sides of Yu Chen, one left and one right, and the three of them were in a triangular formation to protect the 'women' in the rear, intentionally or unintentionally.
