Leng Xuan took a closer look around, and saw that this control room was like a sealed quadrant, and there was no other passage except for two iron doors, one in and one out. Moreover, around the top of the control room, there are also a number of small holes, each of which is only the size of a fist, according to his estimate, it should be a vent. I'm afraid that in order to prevent the enemy from entering the base through the vents, those vents were designed to be so small. However, he really didn't find out the difference between what the dragon head said, so he shook his head and said he didn't understand.

In ancient times, in order to strengthen the defense of the ancient city, people built a wall outside the city gate, and the vacant area between the wall and the main gate is called the urn city, once the enemy breaks through the first line of defense and enters the urn city, then as long as the exit of the urn city and the entrance of the main gate are sealed, then the enemy can be trapped inside for siege and killing. ”

After a pause, he continued: "My control room is built according to the urn city, if this place is breached by the enemy, then as long as the front and rear entrances and exits are blocked, the enemy will have nowhere to escape, and those vents above will also emit toxic gases, and the enemies trapped in it will be wiped out. ”

Leng Xuan asked, "Then what about these staff?"

"When the base is attacked, there will be people who will arrange for them to retreat safely, and if someone can't evacuate to a safe area in time, then those people will have to be sacrificed. However, even if they die, they are glorious, and they are ready to sacrifice for the sake of the national mission. Speaking of this, a trace of ruthlessness flashed in the dragon's eyes, and he said in a straight voice: "This secret base has cost too much of the country's efforts, and no matter what the price is, it must be guaranteed to be safe." ”

Leng Xuan glanced at the dragon head, and at this moment he was very curious in his heart, what kind of secret made the dragon head pay so much attention. By this time, the two had come to the other end of the control room, where there was also a thick iron door. After the faucet went through the cumbersome verification procedure, he led Leng Xuan in.

After passing through a curved passage, Leng Xuan came to the hall of a laboratory, where there were many scientific researchers in white coats who were working hard, and when they saw the faucet, they just nodded lightly in greeting, and then continued to work.

Leng Xuan found that in this laboratory, there were also a lot of glass troughs, which were not much different from the ones he had seen in the base in the Nadeau region. He couldn't help but be shocked in his heart, could it be that the faucets were also conducting human modification experiments here? Thinking of this, he couldn't help but immediately ask.

Hearing this, the dragon head smiled and said, "Your guess is right, we are indeed conducting human modification experiments." However, don't worry, we are not as inhuman as the Blue Dragon Society, and we will try to capture some innocent civilians for experiments. Moreover, our modification experiments are not so disgusting, and we will never do such experiments such as the combination of animal genes with the human body. ”

Leng Xuan was curious: "Then what kind of research are you doing?"

"In fact, our research direction is the same as that of the Blue Dragon Society, and we are also looking for ways to strengthen our personal strength. It's just that we are different from the methods they choose, they are unscrupulous, and we are conducting this experiment based on human nature, and we will not force anyone to be the test subject, nor will we cause irreversible damage to the human body and nature.
