Just as Tang Shuxing and the others went down to the mine, three Black Hawk helicopters appeared on the side of the crater, and after circling twice in the sky, the planes slowly descended, and then the two helicopters landed on the edge of the crater, and put down two teams of soldiers who did not wear any national and military logos. The remaining one hovered directly in the middle of the crater, and after putting down four long ropes, the five soldiers on the plane slid down the ropes one by one, directly to the bottom of the volcano, where Gu Huaiyi had pinned Si Zhengnan's arm before.

After the five soldiers in navy blue combat uniforms and helmets and gas masks landed on the steel plate that covered the crater at the bottom, they immediately dispersed, and after making sure that there was no threat, they took out the palm-sized instrument hanging from their waists and explored around.

"The radiation index is DH45, which is the standard that the human body can bear."

"The oxygen content is average, and the concentration meets the standard of human survival."

"The temperature is 29 degrees Celsius, the perceived temperature is 32, and without the somatosensory water circulation system, it is difficult to support it here for too long."

"The thermal sensor doesn't do anything here, and the instrument doesn't sense the activity of other organisms."

After the four soldiers finished reporting, Andrew, who was standing on the edge of the inner wall of the volcano, took off his gas mask, revealing his face with a mustache and an obvious knife mark on his lips, his light blue eyes stared at the marks left by Gu Huaiyi's dagger on the inner wall, and then slowly retreated, tied his shoulder-length golden hair back up, squatted down and lay on the ground looking at the steel plate on the ground.

"Andrew, there are dagger marks on it. Judging from the traces of the daggers on both sides, it seems that something has been nailed to it, and there seems to be a slight scrap of meat on the inner wall. A soldier approached, adjusted the lens on the mask, looked at it carefully, and then carefully used tweezers to remove the meat residue left by Si Zhengnan and put it into a compression tube, and turned to hand it to the man named Andrew.

"Call me by name, not by name, even if it's just a code name." Andrew looked up and put his mask and gas mask back on. Pressing the intercom, he said, "The two groups of Red and Blue are staying above the crater. Tell the US helicopters to withdraw first, they stay here with too big a target. ”

"RED understands!"

"Blue understands!"

The leaders of the two teams immediately responded, and then pressed the intercom to relay Andrew's order, and the three Black Hawk helicopters immediately turned around and flew in the direction they came. The Red and Blue teams immediately found cover around the crater and lurked.

"From now on. People call each other by numbers. From the 1st to the 4th, you call me the leader. Andrew stood at the entrance and said in a deep voice, "Today is the first time the four of you have carried out a field mission with Operation Group 1540. I hope you all live, and now, repeat the goal of this mission! ”

As he spoke, Andrew turned to look down and heard the four of them answer in unison: "Survey!" ”

"Yes, survey!" Andrew nodded, "That is to say, under the premise of non-self-defense, we can't kill any target, although we belong to the INBC and have a written authorization from the United Nations, but most countries on this planet do not welcome our direct intervention, let's go!" ”

……

At the same time, Tang Shuxing and the others below had already gone deep into the mining area, relying on Ji Kefeng's special perception ability, tracking the two men and two women in front, they were all wearing military chemical protective uniforms, the high-standard kind, each carrying a box, carrying a square backpack, and did not speak along the way, it should be the person who came in the dual-purpose helicopter, as for what the identity is, it cannot be seen from their clothes.

In short, they are definitely not from some rescue organization.

"Oops." Ji Kefeng stopped and looked back at the position he came, "One, two, three, four, five...... Five people, five people came in again, and behind us, they walked slowly, stop-and-go, as if tracking our footprints. ”

Ji Kefeng said this, everyone subconsciously looked at the ground, the ground inside the crater was very dry, the sand and dust floated up, and it was inevitable to leave footprints, and the footprints left by the four people in front were very deep, which was enough to show that the things they were carrying were very heavy.

The fact that two men and two women carry similar things, and that women can carry something of this weight and keep moving forward without resting also shows that they are highly trained and are not ordinary people.

"Don't worry, there's a fork in the road." Gu Huaiyi leaned against the wall of the cave and went out, "There are two holes on the left and right, which one do we go?" ”

Si Zhengnan pointed to the right: "Right." ”

"Good!" Gu Huaiyi nodded, because the four people walked towards the left, which also avoided the possibility of conflict with them, after all, their purpose was only the blue diamond.

Tang Shuxing made an abacus in his heart again, if he couldn't find the mother diamond, he could bring two more small blue diamonds back to make a difference, right? Didn't Zhang Zhikhan and Si Zhengnan do that before? Why should Si Zhengnan be so entangled in the mother drill?

Tian Yehan and Ji Kefeng stared at the back, vigilantly following the five people, waiting for the four unknown people in front of them to turn into the depths of the cave on the left, they slowly touched the cave on the right side of the cave along the right side of the cave wall, just entered the cave, passed through a lower rock cave below, and raised their eyes to see the gold veins in the cave in front of them, the light shone away, and it made people's eyes uncomfortable - these gold ores have not yet been refined, and they can reflect such a high-intensity light, indicating that the raw ore itself has a problem.

"Walk through the gold veins and a few dozen meters inside, and you will reach the blue diamond mining area." Si Zhengnan took the lead and looked very excited, but because he maintained the state of corpse, everyone couldn't see what kind of expression he had on his face.

"Woo Woo Woo-" Gunshots suddenly rang out outside the cave behind everyone, Tian Yehan and Ji Kefeng immediately turned around and raised their guns, waiting for the others to drill through the cave below one by one, then they also climbed over, and then followed Si Zhengnan and ran towards the front, they all knew that it should be those two groups of people who were fighting, and they didn't join in the excitement, so they quickly took the opportunity to get rid of them.

Ten minutes ago, just after Tang Shuxing and the others drilled into the cave on the right, the four people who had originally drilled into the cave on the left side slowly walked out - they didn't know that Tang Shuxing and the others were following them. deliberately walked to the cave on the left, let Tang Shuxing and the others go first, and reversed the situation by himself, from being followed to being anti-tracked.

However, as soon as they came out, they heard the sound of the 5 people of the 1540 action group walking behind them, and it was too late to dodge and go back, so the four of them had to find cover with rocks, each took out the G18 submachine gun from the box, and quietly waited for the 5 people to enter their fire range.

Andrew, the leader of Operation 1540, slowed down. Because he didn't hear much movement in front of him. After raising his fist to signal the team members behind him to hide, he slowly poked his head out, looked at the two caves in front of him, and then felt a glow stick and threw it down. Look at the footprints on the ground. Footprints were found on both sides. At the same time, he also knew that this was a good place for an ambush, so he didn't dare to step forward again, but turned around and gestured with a "drone".

One of the team members understood. Turning the backpack he was carrying to another team member, he asked the man to take out the folding drone from the backpack, then adjusted it and released it, observing around the cave according to Andrew's instructions, and then flew towards the cave on the left first.

The four people at the entrance of the cave on the left are leaning against the cave wall and rocks, leaning down and closing their eyes.

Although the folding drone has tried to minimize the noise, the four-wing propeller still hums, slightly louder than the sound of mosquitoes, but in this kind of cave, the sound is immediately amplified several times.

The woman who was the leader of the four people suddenly got up and raised her hand to drag the drone in her hand at the moment when the drone flew above her head, and then pulled off the probe of the drone, and then the other three people leaned out at the same time very tacitly and fired intensively in the direction where the 1540 action group was located.

The members of the 1540 action team saw that the drone was caught on the screen of the remote control, and before they could raise their heads to report, the overwhelming bullets poured from the mouth of the cave on the left, and the five people immediately buried their heads in dodge, and Andrew and another person in front immediately raised their guns and fired back.

The four men at the entrance of the cave stopped firing, threw a green smoke bomb, and ran into the cave on the left.

The members of the 1540 action group did not dare to go down when they saw the smoke bombs rising, and Andrew also ordered not to shoot.

After the smoke cleared, Andrew led the other 4 people to touch it slowly, and then performed their duties, Andrew squatted down and looked at the messy footprints on the ground, and said to himself: "This is a mine, it stands to reason that there are a lot of people coming in and out, but what are you walking along the way, there are only two different sets of footprints?" ”

"Boss, have we verified our intelligence?" Team 3 asked.

Andrew shook his head: "This kind of thing happened in Asyata, there is no time to verify the intelligence, according to the regulations, we can't have our own informants and intelligence sources, we can only rely on other organizations, but this time someone took the initiative to deliver information, claiming that someone in Astara used something called 'corpse drug' to cause the tragedy in Kanga Province." ”

Although the other 4 team members were busy in their own hands, when Andrew said this, a video taken by some foreigners in Astaya came to mind: those walking corpses in the picture are several times faster and more powerful than ordinary people, and the end of being caught by them is death, but fortunately, the scope of this walking corpse infection is limited, after biting 5 people, bite again, and then the people will only die and will not mutate into walking corpses.

In addition to the video, they received an unencrypted, semi-public email indicating the location of the volcanic mine, photographs of samples of autoclaved drugs, and the process of changing after the soldiers of the National Liberation Front smoked it.

After analyzing the information in detail, the INCB believed that most of it should be true, and it was necessary to go to the location of the volcano to investigate it anyway, so this operation force was dispatched, and INCB is the abbreviation of internationalnarcotics controlboard, which is called the United Nations Narcotics Control Board in Chinese.

Action Group 1540 is a special operations group attached to the INCB, and its name is derived from resolution 1540 (2004), which was unanimously adopted by the United Nations Security Council under Chapter VII of the Charter of the United Nations on 28 April 2004. (To be continued......)
