Looking at everyone's dumbfounded appearance, a touch of pride appeared in Zhang Yuhang's eyes: "This is the method of our family master, how about it, it's amazing enough!"

Everyone was speechless for a while, but Su Fei stared at the holographic three-dimensional structure projection of the underground experimental base, pointed to the last vertical downward passage and asked, "You didn't say it just now, where does this No. 8 mouth lead? Looking at this structure, I'm afraid the deepest part has been one or two hundred meters deep underground." ”

Tang Xueyan followed Su Fei's instructions and noticed this No. 8 passage, and after leaving this hall for a horizontal distance, this No. 8 passage began to extend downward at an oblique angle of about forty-five degrees.

In the end, a vertical downward structure was constructed, which looked like a borehole, and was vertically driven to a place of one or two hundred meters underground, forming a flat rectangular structure.

This area is completely unexplained on the structure diagram.

"Here...... Is this the place where your Zhang family found the raw materials for the pill?" Su Fei rubbed his chin with his right hand, stared directly at the holographic three-dimensional structure projection with his eyes, and sneered: "Let me guess, is that area a karst cave formed by an underground river?"

"Master Su is really powerful. The appreciation in Zhang Yuhang's eyes was undisguised, and he smiled and pointed to the low end of the No. 8 area: "It is here that our Zhang family found that material, which is a mineral that has never been seen before, and we have someone to mine it there, and then transport it to a special laboratory for the refining of active ingredients." ”

"Minerals?!" Su Fei and Tang Xueyan couldn't help but glance at each other, the data in their test report clearly indicated that this was an organic component of some kind of organism, how could it be a mineral?!

Seeing Su Fei so surprised, Zhang Yuhang's face immediately showed a sense of understanding, and said with a smile: "Master Su, do you think that this main material is the flesh and blood of a certain creature?"

"yes, after all, I tested your pill, and the report supports this hypothesis. Su Fei thought for a while, smiled and waved his hand: "Forget it, everything will be clear when you see the real thing." ”

Gong Yang said: "Zhang Yuhang, turn on the monitoring equipment of your entire experimental base. ”

Zhang Yuhang did so, but when the holographic projection was turned on, Su Fei couldn't help frowning.

Except for the four horizontal structure areas from No. 1 to No. 4, the cameras in the other areas did not respond, only gray snowflakes kept flashing, and it was a little strange that there was no one in the four areas from No. 1 to No. 4.

Seeing that everyone's eyes began to examine themselves, Zhang Yuhang smiled bitterly and hurriedly raised his hand to make a gesture of surrender: "You all saw my operation just now, I didn't do anything." ”

Su Fei frowned and pointed to the screen: "Then what do you say is going on, why is there no one, and the surveillance cameras below are all broken? ”

"I can't answer that. Zhang Yuhang tried to output other commands on the keyboard, but unfortunately none of them responded: "I have been away from the base for almost three months, otherwise I would not have been caught by you at home, as for why the base is like this now, I don't know." But it's working time, and maybe they're all underground. ”

"Let's do this first, Gong Hua, you take someone to guard Zhang Yuhang here, and the others are divided into four groups, let's control the area from No. 1 to No. 4 first. ”

The people who came over this time were also the absolute elite of the Gong family, and soon began to carry out Gong Yang's orders, and more than a dozen people were divided into four groups, Gong Yang, Su Fei, Tang Xueyan and Hu Mang formed their own group, responsible for the exploration of the No. 1 living area.

Everyone has a camera on their tactical helmet, and everything they see can be transmitted to other comrades in time.

Su Fei and Tang Xueyan also wore the same equipment, the three of them opened the door of the No. 1 passage and walked to the depths, did the lights flicker twice along the way, and even a broken bulb was still crackling outwards with electric sparks, which made Tang Xueyan always feel an inexplicable depression.

Tang Xueyan's breathing began to be deep, and she was a little out of breath with an obscure pressure. She carried the MP5 submachine gun in her storage bag in front of her and whispered, "Auntie, why do I feel so uncomfortable here?" ”

"It's called claustrophobia, don't be afraid, there are so many of us. Su Fei smiled and pinched Tang Xueyan's pretty face: "But the people of the Zhang family are really powerful, living in such a space is a few months, if ordinary people would have been driven crazy." ”

"Isn't it? Gong Yang, who was walking at the forefront and exploring the way with Hu Mang, nodded: "Anyway, I don't want to live in this kind of place, and I don't want to live in good living conditions." ”

The holographic three-dimensional structure map has been scanned by Gong Yang into everyone's shared database, which can be retrieved at any time on the field of vision panel of the tactical helmet, and it took less than half an hour to walk forward, and after continuous purification of several buffer rooms, the three people and one tiger finally walked to the living area.

The design structure here is like that of a resort hotel, but the building is built one level upwards, while the structure extends downwards, with a lobby on each floor, and then a number of branch-like corridors with small separate rooms at intervals.

Such a design made Su Fei instantly think of an image metaphor: a beehive.

Gong Yang quickly found the central control computer in Area 1, and used Zhang Yuhang to give the password to obtain the central control authority of this area.

Hundreds of surveillance cameras were immediately projected on the large screen in front of them, which was a more detailed surveillance camera than in the lobby before, and could be captured in almost every hallway.

But it was still empty.

Using the central control authority of No. 1 Go, Gong Yang forcibly blocked the electronic door locks of each layer of the hive, so that even if there were people in the room, they could not get out, and in the surveillance cameras, no one was found in the corridor.

Su Fei searched the list on the central control system, pointed to the screen and said, "You see, there are indeed only thirty-seven people in the entire base, all of them are working and researchers, and most of the areas under the hive are not open, and these people only live on the first and second floors at the top. ”

Tang Xueyan: "Then what should we do next? Let's open the doors one by one and pull out those unlucky ghosts who are squatting in the room and sleeping lazy?"

"So be it. Gong Yang nodded.

This time, Tiger Mang was at the forefront, sniffing back and forth, and if there was anything like the same smell in the air, he would be the first to warn.

Looking at the annotation on the system, the first layer of the hive was inhabited by male alchemists and staff, with the help of central control authority, Gong Yang used the tactical computer in his hand to open the rooms one by one, and after searching all the rooms, everyone looked at each other a little.

"There really isn't a single one. Tang Xueyan glanced at the entire room and said suspiciously: "Auntie, I feel that something is wrong." You see, these things are all thrown around on the bed, and the things on the table and in the drawers are also turned around, and normal people would make their nests look like this. ”

Su Fei glanced at the clothes on the bed, and then opened the door of the wardrobe, and the clothes that were supposed to be neatly hung inside with hangers were all messed up.

The furnishings in the previous dozen or so rooms were neatly arranged, just like the dormitories in the barracks, which also made the messy dormitory where everyone was now a little abrupt.

Su Fei pondered: "I think that the people who live here seem to have packed up some things in a hurry and left, leaving in a hurry, so they made the room look like this." ”

"I think so too. Gong Yang nodded, he rummaged through all the things in the drawer, and suddenly took out a box from a drawer: "Come and see!"

This is the case of the gun containing Ger-Lock, but it is empty at the moment, except for the Ger-Locke 18 pistol, and the two magazines in the box are also missing, apparently hastily taken by the man in the room.

At the same time, Hu Mang also sniffed twice on the cabinet, and actually opened a hidden compartment from the cabinet, and there was a special bracket for hanging firearms on the hidden grid that was pulled out, and the guns on the bracket were also missing at this moment.

Su Fei asked, "Who lives in this room?"

"It's a man named Daniel Zhang, forty-two years old, the captain of the security here, cultivating to the peak of the ninth layer of the Zhiwei Realm. The following information shows that-" Gong Yang's eyes shrank suddenly, and he looked up at Su Fei with some solemnity: "At the same time, he is also one of the main persons in charge of Area 8. ”

"Eight, isn't this the area where the rough mineral is mined......"

Su Fei also felt the strangeness inside, it was work time, a security captain was not on duty in his position when he was at work, and he actually ran back and hurriedly took the firearm and left, what is the reason?

And there shouldn't be anyone else in the base except for the alchemists and staff of the Zhang family, who are they going to deal with?

If this is the case in the whole room, it is also possible that the Zhang family received some order to evacuate all. However, the other rooms are neat and tidy, which obviously does not support this inference.

Things are a little weird......

Just as Su Fei, Tang Xueyan and Gong Yang were puzzled, the entire hive suddenly made a loud buzzing sound, and then the lights above everyone's heads suddenly went out!

The originally bright surroundings fell into pitch black, and everyone's nerves tensed instantly, and they immediately formed a defensive triangle back to back, and the muzzles of the guns were pointed at the periphery! Su Fei instantly opened the Cave Divine Eye, and even pricked up his ears to listen quietly, but after a second of suppression, nothing happened.

At this moment, there was a sudden murmur on Gong Yang's walkie-talkie, followed by a loud bang on the iron door!

And a flurry of violent rifle roars!
