The situation is unclear now, and Jiang Yanhai can only lead the team to enter by himself, and no one stops him, because everyone knows that Jiang Yanhai has strength in this area.

Although it is impossible to confirm, the lion fights with all his strength and no one knows what is happening inside. There is no mistake in making the surrounding troops alert.

Jiang Yanhai also drew team members who were familiar with whom he had strong practical skills to form a combat team.

As for the others, they were on standby around. Although even if enemies entered, there should not be many people. Jiang Yanhai believed that the people he brought could handle, but it was right to be fully prepared.

Jiang Yanhai's order was delivered, and the Ninth Quick Response Brigade of Logistics took action immediately. All the logistics supplies that the team members needed to prepare were quickly loaded onto the transport plane, and Jiang Yanhai and the others would directly parachute to the target area.

Because they will enter from the collapsed passage, the front passage has been completely locked and cannot be opened from the outside.

The entire base instantly looked like a hornet's nest that was alarmed. Countless people rushed out from different positions and rushed to their posts quickly.

In fact, at this moment, two transport planes were already hovering over the target. These two transport planes were loaded with different individual device kits. Whatever Jiang Yanhai needed, they would fly directly to the target and airdrop it.

The Ninth Quick Response Brigade of these materials has been prepared in advance.

What needs to be prepared now is the weapons and equipment of the subsequent team members.

Jiang Yanhai and his team replaced the full camouflage combat uniforms as fast as possible, and boarded the plane directly with parachutes on their backs.

With their boarding, a Y20 transport plane quickly took off directly on the runway and headed straight to the destination.

They are not too far from their destination, and the flight time is only more than half an hour. At the end of September, the temperature on the top of the Qilian Mountains was already below 0 degrees and there was already snowfall.

When they arrived in the area, the road to the area that could be seen from the plane had been blocked.

When the plane lowered to a height of 3,000 meters, the cabin door behind opened, and Jiang Yanhai and 16 others jumped directly from the plane.

A few minutes later, Jiang Yanhai and others had landed on a wasteland. Not far from them were two large parachute gear boxes composed of countless small personal equipment boxes.

Everyone rushed over immediately after landing on the ground. Behind Jiang Yanhai and the others, another new umbrella flower composed of three parachutes was slowly falling.

"He Chenguang carried a large-caliber reverse equipment sniper rifle, and everyone else carried a Type 19 automatic rifle, and was equipped with three shotguns. The blaster should be careful to carry a blasting device, Zhuang Yu and Xu Tianlong, go there to carry a communication support device." Jiang Yanhai quickly assigned everyone the task.

"Tong Li and Song Kaifei's heavy weapons have two ammunition bases, and the others have one ammunition base, plus a grenade launcher, equipped with fragments, smoke eggs, night vision instruments, infrared thermal energy detectors, and life detection devices. Each person is carrying a set of three-defense devices first, and then enters to allocate the combat plan according to the situation."

Everyone silently put different combat components on themselves. In 10 minutes, everyone was ready. Looking at the tunnel that had collapsed about 300 meters away from them, Jiang Yanhai waved his hand directly.

16 people rushed to the other side of the tunnel. The entire tunnel entrance was covered with gravel collapse, and some weeds even grew here, indicating that no one came here for many years.

Instead of looking at the gravel, they started to climb the mountain quickly from the side. After climbing at least five or six hundred meters perpendicular height, at the other angle, a dilapidated natural cave half covered by gravel appeared in front of everyone.

Jiang Yanhai turned on the device in his hand and looked at it, confirming it was here.

"Night Vision! I took the lead in and the others followed one after another. At the beginning, the position was narrow. Pay attention to keeping the distance. Xu Tianlong and Zhuang Yu, you two, have established a signal transmission device along the way."

"clear!"

In fact, there is a scanning system, and these can be ignored, but only Jiang Yanhai knows this, and he cannot let others see it.

After taking the lead in entering, the cave was very narrow at the beginning, and some areas even required people to crawl through. The traces here showed that wild animals had entered and exited here, but there were no traces of people other than that.

The tactical flat panel device on Jiang Yanhai’s wrist has a positioning system and contains a structural diagram of the cave, but no one has been in here for at least thirty years.

No one knows whether it will collapse due to geological changes.

After going deeper into it for more than 200 meters, and then crawling for 50 meters, the space around them began to become wider again, so that they could stand up.

Jiang Yanhai did not continue to move forward immediately, but began to be alert here and wait for the others to crawl out one by one.

After everyone came out, Xu Tianlong, who was at the end, was the last one to come in. After coming in, Xu Tianlong immediately took out a 20-cm diameter device from his body, and directly stuck it to the stone next to it, and then turned on the switch on it.

"The signal is stable." Xu Tianlong looked at Jiang Yanhai and spoke.

This is a signal transmission device, which is a bit like the principle of mother-and-child routers. The signals can be transmitted to each other. Finally, the signal docking is completed by a large signal transmitting device built outside the cave, an electronic warfare aircraft in the sky, and a communication support vehicle driven from nearby ground.

In this way, Jiang Yanhai and the others can communicate with the outside headquarters at any time, and even transmit high-definition images to the outside.

Its internal reinforced internal battery allows it to maintain high-intensity signal transmission for 5 hours.

"Forward." Jiang Yanhai nodded, then quickly led the team back to advance, and the cave here was twisting.

Although it is not a man-built maze, it is similar to a maze. If you don’t bring the device in, it is very likely to be lost in this cave.

And you don’t know if there are snakes or other wild animals that are dangerous to humans, but Jiang Yanhai has not yet discovered it.

About 20 minutes later, the area around Jiang Yanhai and the others was already very vast, but there was a dead end in front of them. However, Jiang Yanhai's scanning system scanned it. This place was the secret emergency passage left specifically.
