Yuan Muye said with a smile when he heard this, "It's as if we humans haven't worked underground, don't forget that humans will go deep underground to explore when they dig mines......"

After hearing this, Li Chen said in a deep voice, "Do you know why large and small mining disasters occur all over the world every year? It's because you humans have crossed the line. ”

Yuan Muye saw that Li Chen was serious, and it didn't seem like he was joking at all, so he asked him if he knew something? But Li Chen said that there are some things that he can't say too much, in short, when a human goes to the underground world, it is the same as when he comes to the human world, and there are dangers everywhere......

After arranging Li Chen, Yuan Muye still had to take a look at Zhao Ling'er and Datou, this time Lao Lin would go with them, so that if the two of them really encountered any trouble, there would be no one to help them on the 54th.

After thinking about it, Yuan Muye still gave Xu Li's mobile phone number to Zhao Ling'er, "This is my friend's mobile phone number, we will go abroad in a few days, if you encounter any trouble during this period, call him, don't act privately." Remember, he's a police officer...... So the identity of the big head can't reveal too much to him! ”

Zhao Ling'er nodded knowingly after hearing this, and said, "Okay, I know, you can go with confidence, I will take care of the big head here, and I promise not to let him cause trouble for everyone." ”

The next morning, the No. 54 group took a special plane and flew directly to the destination of the trip, a dense forest in the north of country U. Although Lao Lin also went with everyone this time, Forging Feng finally decided to let him stay on it as the last guarantee for everyone, in case something really happened...... Someone has to advocate for rescue.

At first, Yuan Muye and the others thought that the test base must be under a normal building, but when they arrived at the place, they saw that it was actually in a natural cave that was very deep in itself, so it seemed that the test base was definitely not just a few hundred meters deep......

Standing at the entrance of this natural cave, several of them looked up, feeling as small as ants, and several of them were immediately shocked by the magic of nature.

"I'll it! With such a large natural cave, how could country U allow scientific research institutions from other countries to study it? Zhang Kai said with a surprised face.

Liao Heyong explained after hearing this, "Of course it's not in vain, this cave is rented by us at a high price, and the lease period is twenty years, and today it is only the seventh year." ”

At this time, Forging Feng whispered to Yuan Muye, "That means that it has been studied for four years before it happened, and it seems that the following problems are not small......

When Yuan Muye heard this, he smiled and said to Liao Heyong, "Dr. Liao, you see that we have already come here with you, and we will be on the verge of leaving, can you tell us more about the following situation now, and let a few of us be mentally prepared?" ”

After hearing this, Liao Heyong thought about it and said, "Actually, I don't know much about what happened back then, because I was being sent back to the headquarters by the teacher to make a report, so I escaped this catastrophe, otherwise I would have become an ownerless and lonely soul, where can I stand here and talk to a few people......"

After that, Liao Heyong told them that he was temporarily called back by the headquarters because there was a little problem with this subject, but as soon as he returned to the headquarters, he heard that there was an accident at the test base, saying that there was smoke coming out of the cave for unknown reasons, and it should be that the underground base was on fire.

So Liao Heyong didn't have time to report to the leader, and hurried back to save people with people, but when they came to the research institute located at the underground entrance, they found that the elevator leading to the test base had started the power-off protection device because of the fire, and it was stuck at the bottom.

There is no elevator, and the entire passage is full of smoke...... Not to mention going down to save people, it is estimated that before they get to the bottom, people will be directly choked to death by these black smoke. And even if the rescuers go down now, the researchers below have no chance of surviving, so they finally have to choose to completely close the test base, and the fire will naturally be extinguished when the oxygen below is exhausted.

After hearing this, Lao Lin said thoughtfully, "In other words, it is possible that the corpse and the test data were not destroyed by the fire?" ”

Liao Heyong sighed when he heard this, "It's just that there is this possibility, because we don't know where the fire is, the space of the base is not small, and it takes a certain amount of time to run out of oxygen, plus the fire has been burning for a while when I take people back, so if the fire point is in the core area, it will definitely be burned out." ”

After that, they were picked up by a black minibus and drove all the way to the depths of the cave, and after about ten minutes, the minibus took them to an area full of white buildings inside the cave. These white buildings are supposed to be important hubs that connect the above-ground and underground areas......

When Yuan Muye arrived, there were already a group of people doing the debugging of the equipment inside, and the first thing they had to do was to open the ventilation system of the underground test base and fill it with oxygen below, so that the members of the rescue team could go down smoothly.

It's a pity that they tried several times before, but they have never been able to restore the power supply, it should be that the circuit in a certain area below is seriously burned, and if they want to completely restore the power system, they can only send people down to repair it.

Naturally, Yuan Muye doesn't need to worry about these things, there will definitely be professional maintenance personnel to go down with them, and now the most worrying thing for Forging Feng is whether the equipment promised to them before will be ......

Fortunately, that Liao He Yong spoke and counted, not only arching the weapons that Forging Feng had asked for before, but also preparing some emergency survival equipment, such as oxygen masks and the like, to ensure that they still have time to evacuate when they are short of oxygen.

Although it is said that this time is many times better equipped than in previous operations, Yuan Muye's heart faintly feels that there are great hidden dangers underneath, first of all, they don't know what this test base was studying underground back then? The warning from Li Chen was still in his ears, and he couldn't be unsuspicious.

Besides, looking at the scope of the buildings on this ground, Yuan Muye didn't believe that everyone was underground when the accident happened, and there was no one left in the huge space above? Do you have to wait until Liao Heyong brings someone back to fight the fire? This argument is obviously untenable.

In addition, it is not difficult to find from Liao Heyong's introduction just now that they can go down to rescue immediately after the fire is extinguished, and they don't have to wait for three years later, why did Liao Heyong's superiors refuse to approve it?
