Gong Yang had already prepared three helicopters and just went to explore the laboratory, so Gong Wenliang and Kui Xing waited in the family, and Gong Yang and more than a dozen elite people of the Gong family escorted Zhang Yuhang there.

Su Fei decided to follow and take a look, and Tang Xueyan and Hu Mang also followed, which could be regarded as a response. In addition to Hu Mang, the Gong family prepared a set of special forces protective clothing for everyone, from tactical helmets, body armor, waterproof boots and even automatic rifles and submachine guns.

The group flew in the direction of Yecheng.

According to Zhang Yuhang's guidance, everyone did not go straight to the old house of the Zhang family in Yecheng, but ran to the depths of the mountains around Yecheng.

The helicopter circled the mountains several times, and finally found a small lake hidden in the mountain col under the guidance of Zhang Yuhang, which was the destination of the trip.

"This is our Zhang family's secret research institute, except for me, Zhang Chengzhuo and a few Zhang family members, even Zhang Kan and Zhang Kui don't know this place. ”

Zhang Yuhang pushed his glasses, walked in front and guided everyone into a cave next to him, Su Fei turned on the searchlight flashlight on his head, surrounded by craggy stone walls, it was obviously a natural cave.

After walking about one or two hundred meters, traces of human construction finally began to appear in front of me, a huge alloy door separating the depths of the cave from the outside, with a palm-sized combination lock on it, as well as iris inspection equipment and infrared imaging inspection equipment.

Zhang Yuhang first took off his glasses, aimed his pupils at the iris testing equipment, and then completed the infrared imaging test under the camera, and finally entered the password.

The huge alloy door rumbled open, and inside was a large passage more than twenty meters wide and more than ten meters high, like a tunnel through the mountain, reinforced by cement, and above it were two rows of dim lights, but half of them didn't seem to be in good contact, flashing non-stop, not making crackling electric sparks.

"This is our Gong family's research base. ”

Zhang Yuhang put on his glasses, and his fingers began to tremble again when he heard the mutated appearance of those clansmen he saw yesterday: "It was here that we found the raw materials of that pill, and in order to prevent leaks, we sealed off the entire place and built a large underground laboratory." ”

Su Fei sneered: "The Zhang family is really bloody, such a laboratory is no less than an underground fortress, I'm afraid it will be at least a billion to build!"

"I don't know exactly how much it spent, my team and I were only responsible for research. The technicians in this experimental base are basically isolated from the world, and they only go out in shifts every two months, and they should not know the news that Zhang's family has been destroyed. ”

Zhang Yuhang helped his glasses, walked to the inner wall of the door and pressed a button on the wall, but the small screen above did not appear as he thought, but only a snowflake.

At this moment, the red light on the alloy gate flashed, and the fiery red light like a police car swept back and forth, with an alarm, and then the alloy gate slowly closed.

Seeing that the last trace of fresh air behind him was also blocked by the thick alloy gate, Su Fei took a deep breath, and an inexplicable boredom suddenly welled up in his heart, which made him a little anxious.

Zhang Yuhang motioned to everyone to be calm: "It's time for the door to open, this is the program set up by the laboratory." ”

"Gong Hua, you bring four brothers in front, and the people behind us follow. ”

Under Gong Yang's deployment, everyone soon began to explore inward.

Hu Mang walked quietly beside Tang Xueyan, his four fleshy claws made him not make a sound when he walked, the tiger nose sniffed lightly twice, and Hu Mang frowned: The air here is really bad, are you sure you won't suffocate here?"

"No, it won't. Zhang Chengzhuo looked at this underground fortress, and even his eyes were full of pride: "This is the most perfect work of our Zhang family, designed and planned in full accordance with national military standards, all kinds of facilities are readily available, even if the third world war starts outside, the resources here are enough for us to live self-sufficient for more than three years." ”

Su Fei said with a smile: "It seems that Zhang Chengzhuo has really invested in blood, if he can really get Luoying Senhai, these investments are worth it, but unfortunately, they are all used in the wrong place......"

The pride in Zhang Yuhang's eyes disappeared instantly, and he looked at Su Fei with a wry smile: "Master Su, you have such achievements at a young age, and from the perspective of an alchemist, I admire you incomparably." But we have a family behind us, and the interests of the family can always come first, and I don't want to study this here, but ......"

Su Fei recycled and interrupted Zhang Yuhang's emotion: "Needless to say, let's go, take us to the core of the base to have a look." ”

Everyone walked inside under Zhang Chengzhuo's guidance, and sure enough, as Zhang Yuhang said, square ventilation pipes began to appear on the wall, and the inward openings were welded by alloy shutters. Judging from the freshness of the air blowing into the experimental base, these passages should be able to lead directly to the outside world.

After walking more than 100 meters to the end of the tunnel, there is a vertical elevator, according to Zhang Yuhang, this elevator is the only entrance and exit of the entire experimental base, and they will take the elevator to descend dozens of meters to the formal area of the laboratory.

Zhang Yuhang opened the elevator through the red film scan, and then heard a sound from deep underground, and the elevator was gradually going up.

The elevator door is a triple built-in folding design, and the space inside is equivalent to three or four times that of a high-rise elevator with ecchymosis, which is enough to take more than 30 people and send everyone underground at one time.

Zhang Yuhang was sandwiched in the middle by everyone and squatted with a tiger at his feet, which made him unable to move at all. Fortunately, the elevator descended quickly, and it didn't make everyone suffer for long.

When the elevator opened, a disc-shaped hall appeared, large enough to accommodate hundreds of people.

The bright crystal chandelier above, and the surrounding walls also have a variety of decorations full of technology and futuristic sense, and there is a kind of gorgeousness. This is not so much an alchemy laboratory as a banquet hall.

"This is the central area of our experimental base, but it is mechanically controlled 24 hours a day, and if outsiders strayed into this place, the tunnel above will become the first line of defense of the experimental base, and this is the second line of defense. ”

Zhang Yuhang walked to the wall and clicked twice on a palm-sized device on the wall, and then the wall in front of him opened a hole and flipped out a half-human-high beverage device from the internal test

Zhang Yuhang pressed a button, and a paper cup popped up under the beverage equipment, and coffee began to be poured into the top, and the strong aroma of coffee gradually spread outward.

"Does anyone want coffee?" Zhang Yuhang took a sip of coffee: "Don't worry, it's non-toxic." ”

"Thanks, no need. ”

Gong Yang ignored it, leaving four people to guard Zhang Yuhang, and the other Gong family soldiers scattered separately, installing their cameras and other equipment throughout the hall.

"Bring me a drink. However, Su Fei unceremoniously ordered a cup for himself, gently sniffed the aroma of coffee, and smiled and gave Tang Xueyan, who was standing behind him, also a quilt: "The high-quality coffee beans from Ethiopia will be wasted if you don't drink them." ”

"Oh, that's for a drink. Tang Xueyan laughed and turned out the paper cup handed by Su Fei, since Su Fei drank it, this coffee should be fine.

Su Fei suddenly patted Zhang Yuhang's shoulder from behind: "I have always had a question, I don't know if Master Zhang can solve my doubts." ”

"I don't dare to be a master in front of Master Su, please say something. ”

Zhang Yuhang is very respectful to Su Fei, in the world of alchemists, the concept of "learning no size, the master is respected, there is no order of learning, the master is the first" is deeply rooted, for Su Fei, who is comparable to the level of the seven-grade alchemist, Zhang Yuhang respects from the bottom of his heart.

Su Fei smiled: "I'm just curious, why the Zhang family seems to like the G-Lok series of pistols very much, I think you guys from the peripheral members to the family members seem to like this design." ”

This question has been in Su Fei's heart for a long time, whether it is Liang Gong who he saw at the beginning, or Zhang Kui and Zhang Kan who he saw later, each of them is equipped with a pistol like Glo-Ke.

"It's no secret. Zhang Yuhang glanced at Gong Yang and smiled: "Master Su can actually ask Gong Yang, our Zhang family has always cooperated with Night Crows, and the firearms are all purchased from them, so ......"

"Oh, see, Night Raven does like G-Lok. ”

Su Fei sneered in his heart, and secretly said that this was indeed the case, in Huaxia Night Crow, these unsightly killers had an inexplicable fanaticism for G-Lo-Ke, since the Zhang family's weapons were obtained from the Night Crow, it was not surprising that there were so many G-Lo-Ke.

However, Su Fei was still taken aback, he thought that Night Raven was just a killer organization, but he didn't think that he was secretly trading arms, and even Su Fei suspected that underground arms trading was their main business, and assassination was just extra money!

"Report, camera No. 1 has been debugged and there are no problems. ”

"Report, camera number two has been commissioned. ”

"Report, camera number three has been commissioned. The recording equipment has been debugged. ”

Report ,......

............

Gong Yang listened to the reports of his subordinates one by one, and at the same time he put on his tactical helmet, and several camera areas appeared on the projection of the tactical field of view on the left eye on the inner edge of his helmet, which was the picture from the camera.

Gong Yang nodded, turned around and walked towards Zhang Yuhang: "Zhang Yuhang, where are we going next?"

Zhang Yuhang took the last sip of coffee in the cup and drank it cleanly, crumpled the paper cup into a ball and threw it into the trash can next to him, and then walked to the center of the hall. He tapped twice on the hill in the middle of the hall, and immediately began to hear a roar of air beneath his feet, and then the floor below flipped open, and a half-man-tall console rose.

Zhang Yuhang tapped quickly on the keyboard of the console, and after pressing the last enter key, the console slowly stood in a circular projector, and under the flow of light and shadow, a holographic three-dimensional structure projection appeared in front of everyone.

"This is all the structural drawings we have in our entire lab. Zhang Yuhang pointed to the holographic three-dimensional structure projection and explained.

Su Fei felt that he had a clear understanding of the strength of the Zhang family, but after seeing this structure diagram, he suddenly overturned all his previous assertions. Zhang Chengzhuo really deserves to be a careerist, and this experimental base really opened Su Fei's eyes.

On the holographic three-dimensional structure projection, with the hall where everyone is currently located, eight passages are derived from the spread like a spider web. Each passage leads to a functionally independent area.

The No. 1 passage leads to the living and rest area of the underground staff, where they sleep, eat and play.

The second channel is the planting area, planted with many green plants, and through photosynthesis, to ensure the oxygen supply of the entire experimental base, even if there are any big changes in the outside world, the oxygen produced here is enough for hundreds of people to consume every day and night.

Passage 3 leads to the warehouse area, where there are not only food warehouses, but also a series of warehouses such as munitions warehouses, medicine warehouses, alchemy finished products warehouses and medicinal herb warehouses, where all the necessities of survival can be found.

Passage 4 leads to the water source, the first three of which are all built horizontally, while this passage is dug diagonally into the ground, and then after several turnarounds - into the water purification area, where not only does a pipe lead directly into the deeper ground to extract water, but from here there are countless pipes that lead to various areas of the entire experimental site. Contaminated water is also sent here, and if necessary, it can be purified and reused, creating an internal water cycle.

No. 5 and No. 6 are the alchemy test area and finished product inspection area, and No. 7 is according to the risk level of alchemy, different dangerous goods test areas have been set up, the three areas are adjacent, and the structures built are all stepped downward extension mode, the further down the alchemy room and the higher the level of the inspection room. There was even a well-established fourth-level laboratory at the bottom, which frightened Tang Xueyan!

The eight areas are not completely independent, and there are several horizontal passages below that will be connected to each other, connecting the entire underground experimental base as a whole, so it is completely possible to directly enter the first rest area from the fifth or sixth area from the underground to the first rest area after the alchemy is over.

Unless you want to go up to the surface and leave this underground test base, there is no need to transit through this hall at all.

The huge underground structure design and intricate regional planning made Gong Yang feel a little breathtaking, although he was an enemy, but Gong Yang also had to sigh at Zhang Chengzhuo's courage and means, and actually spent a lot of money to build such a huge underground fortification, it was unimaginable!
