Two hours later, Jiang Yan Hai had appeared on Base No. 9. Following Jiang Yan Hai was a Phantom Fighter Jet, which was just above the Phantom. The Phantom's powerful electronic system had accepted the information transmitted from the ground.
In fact, Jiang Yan Hai looked at Er Dan in his own mind. The base is somewhat similar to the Yu City base. The difference is that it is located inside the Qilian Mountains. It is also entered through a tunnel. However, the difference is that its road is blocked.
Ordinary people's vehicles cannot use this road, because it is not connected to the outside world, and the only town it is connected to is actually a village and town belonging to the research base.
In the northwest, there are not many people in such small towns, and they are not large in area. They are also located in a remote corner, and there are usually no outsiders coming and going.
Even the locals don't know this information, they just think there is a small town here.
The other side of the tunnel was actually collapsed by artificial explosion, but to outsiders, they would just think that the entire tunnel collapsed directly. There is no way to enter from the other side, and the road on the other side is also in an abandoned state.
In fact, this is the entire secret research base. The research base covers a large area, and its tunnels are also very wide. The tunnel with a total width of 22 meters can theoretically allow any fighter jet to enter, but the reason why this tunnel is so wide is not to allow fighter jets to enter.
But sometimes it is necessary to transport some special experimental equipment, and many of the equipment are relatively large, so the tunnel will have such a large area when it is first established.
The base went inside, hollowed out the entire mountain, and used Nuclear Protection Engineering. Its total internal depth is 150 meters. It was built using a natural cave that originally existed inside. Its bottom area is the largest, and the entire cave has undergone nuclear protection reinforcement.
It has only two front entrances, and there is a separate secret passage connecting the other end of the internal cave, but that place has been artificially closed and will not be opened to the outside unless it is an emergency.
As for other ventilation devices, there are various protection measures, and if it enters the first-level lock state, even this ventilation device cannot be entered.
Jiang Yan Hai has seen the drawings of the entire base, but the point now is that they still don't know what happened.
Jiang Yan Hai entered the command hall, Fan Tian Lei and they were all here.
"Is there any order passed down from above?" Jiang Yan Hai asked immediately.
"You have full command. The current base blockade time is 2 hours and 42 minutes. According to the information passed back above, after the entire research is completely sealed, its internal air circulation system will automatically start, but this can be turned off by the person who blocks the base."
"If the circulation system is activated, the internal air circulation system can allow all personnel inside to use it for 24 hours, but if it is not activated, the internal air circulation can only allow the personnel inside to survive for 6 hours." Qiao Fangyuan immediately introduced.
"Where are the security personnel at the base?" Jiang Yan Hai frowned.
"In order to maximize its concealment, the base does not have many personnel. It only has garrison troops around the base. After all, more personnel require more material reserves. There are currently 72 researchers and 12 logistics personnel sealed inside the base. There are 232 security and logistics personnel in the base, and all the remaining 220 people have been evacuated."
"The blockade started from the core laboratory area. Security personnel in this area are not allowed to enter. These 12 logistics personnel are the only ones who can enter."
"Where is the electronic system?" Jiang Yan Hai frowned.
"All connections are disconnected. Judging from the current form... it is like encountering an electromagnetic pulse bomb. All the internal instruments have been destroyed, and all connections with the outside world have been cut off."
"The power was also interrupted?" Jiang Yan Hai took a deep breath.
"It is currently impossible to determine the internal power supply system, but the external power supply computer room has been burned down. According to the description of employees in the external power supply computer room, before the power was interrupted, the power consumption suddenly reached a peak, and then burned down instantly." Qiao Fangyuan quickly introduced the situation.
Jiang Yan Hai frowned tightly. If too many high-power electrical appliances are used in the home's internal power supply, the circuit may trip. However, you will know how much power the circuit supplying the secret base can hold, just think about it.
Therefore, it is impossible to cause power outage due to internal research. There is only one reason, there is an unknown energy burst inside, such as electromagnetic pulse.
"What is this base... researching for?" Jiang Yan Hai thought for a moment before asking.
"The chief said that if you ask, he will tell you that he came back from Africa." Qiao Fangyuan They didn't know, but they still gave him a sentence.
Hearing this, Jiang Yan Hai nodded, he guessed it.
More than a year ago, the mysterious cargo from Africa "Who Am I" that landed at the Overlord Wolf base is unknown to where it was sent, but it is estimated that it was sent here.
"Are you sure if someone is attacking?" Jiang Yan Hai took a deep breath and asked.
"It's impossible to be sure. According to the security personnel, the base's confidentiality measures are tight. Theoretically, it's unlikely that someone would sneak in from the outside and they wouldn't be able to detect it, especially if they sneak directly into the core area."
"However, this theory is not absolute. The base is connected to an underground river. The groundwater there is the source of the base's drinking water source. The underground river can indeed lead to several secret exits nearby."
"The problem is that the passages in the underground river are complicated. Even our current unmanned underwater detectors cannot fully detect them. People dare not go deep into it completely. Unless someone has a complete grasp of the flow of the underground river, it is unlikely to sneak into the base."
"And even if you enter from the underground river, it is not easy to evade the security personnel. This is the only loophole that may occur." Qiao Fangyuan shook his head.
"The key point now is that the sensors placed in these areas have been completely damaged, and we can no longer connect to get data." Black Eagle, who maintained the network connection with them, said helplessly.
"Understood, have all the personnel returned to the team now?" Jiang Yan Hai asked immediately.
"Special Operations Regiment's main members are all here."
"Add Yang Rui, Xu Hong, Gu Shun, Li Dong, Zhang Tian De, Tong Li, Zhuang Yu, Lu Shen, Chen Shan Ming There are 16 people in total including E, He Chen Guang, Li Er Niu, Wang Yan Bing, Song Kai Fei, Xu Tian Long, and I will lead the team myself," Jiang Yan Hai said decisively.
"Yes!"
"Order, two Phantoms and two J20s of the air combat unit take off, one large Early Warning Aircraft, one Electronic Warfare Aircraft and two Reconnaissance Drone enter the battlefield. Order 9th Rapid Reaction Brigade to transport Special Operations Regiment to a place 2 kilometers away from the base and wait for orders at any time."
"The artillery regiment entered an attack posture and issued a request to its superiors, requesting the original guarding troops near the base to enter a first-level combat readiness state."
"Yes!"
