"Go on!" Wan Qingshan is still calm, and he is most afraid of impatience when encountering such an enemy.

Soon a three-meter-long mechanical centipede climbed down, the mechanical centipede has an infrared detection function, and the most important thing is that this mechanical centipede is a photonic system, and the main materials are engineering plastics; Of course, today's engineering plastics are also very strong, which is enough to meet the needs of such robots.

When the mechanical centipede crawled to the entrance of the cave, it suddenly turned around, stretched its back into the hole and began to swing continuously, but the front half of its body was fixed to the poor reinforced concrete fault. The tail part of this mechanical centipede has a detection head, and there is more than one detection head of all sizes, including infrared technology, visible light technology, sound wave technology, and heartbeat detection technology.

This time the probe finally discovered the general situation inside; But I'm sorry, this mechanical centipede didn't exist for three seconds before it was destroyed by a single shot. Three seconds, just enough time to shoot a corner with nothing.

Watching the second half of the mechanical centipede turn into pieces, Wan Qingshan immediately made a decision, and the shock bomb was launched!

At the sound of an order, several shock bombs of different specifications were dropped, and the strong light and loud noise echoed in the confined underground space, and the stun bomb was definitely one of the most suitable weapons in the enclosed space. The high technology makes the effect of the shock bomb better and "excellent", enough that ordinary evolutionaries cannot bear the strong "shock".

Even Qin Fei, who was in the outside world, felt the unbearable noise, let alone the people in the underground space.

"Go ahead and release the probe!" Wanqingshan will definitely not let people take risks easily, what is high-tech for, isn't it to take risks instead of people. One of the most important functions of the mecha is to carry load. Powerful mechs can carry countless tools with them, and the Probe will always be one of the most needed pieces of equipment.

The various detectors roll down like dumplings, and these detectors themselves are small robots that can move freely. What visible and invisible light detection, heartbeat detection, air composition detection (mainly for viruses, poisonous gases, etc.), electromagnetic detection (mainly for weapons, traps), etc., a series of investigations, basically can identify most of the more obvious dangers.

As for some of the dangers that are not obvious, it is difficult, and many things can only be grasped blindly even when experts come - science and technology are always advancing; Moreover, in the field of science, it is also divided into two sequences: standard and non-standard. In the military industry, there are far more non-standard technologies and equipment than standards, especially a variety of technical tests, combinations, etc., which are enough to make any expert's nerves knotted.

The probe soon came with a relatively clear picture of the scene.

There were no personnel, just a few low-level robots that had fallen to the ground - the lower half of the body was still designed on wheels.

Several high-voltage wires were found, and the reconnaissance robot had cut two of them by self-sacrifice; There are also several high-voltage wires buried in the walls, which are more dangerous.

An electromagnetic pulse device was found, which has been destroyed.

Two items suspected of being time bombs have been found, requiring further judgment, and the danger level is unknown.

Four cavities were found in the walls, the condition is unknown.

The remaining 12 suspected dangerous goods could not be detected.

This was followed by clear photos of the scene, and after the shock bomb, many low-level robots had been scrapped, and the danger had been lifted, at least temporarily.

"Sniper, destroy these positions." Wan Qingshan passed the information to the sniper Liu Xiaolong.

"Okay!" On the internal channel of the 33rd detachment, the sniper Liu Xiaolong's 'cheerful' voice was heard, and Liu Xiaolong's soul was seen crawling down the hole, the mecha stayed above the hole, and the right arm of the mecha grabbed the sniper rifle and went deep into the hole.

But wait a minute, there is a reinforced concrete layer seven or eight meters behind the entrance of the cave, and the length of the mecha's arm is not enough......

It didn't matter, then Qin Fei saw that the mechanical arm of the mecha was actually stretched out like a jack; The upper arm and lower arm turned out to be telescopic structures, and the mecha arm, which was originally only five or six meters long, was extended to ten meters in length, and it seemed that it could continue to extend.

But ten meters is enough. The sniper rifle had penetrated deep into the hole, and then the thud continued to be heard.

Qin Fei heard the report from the communication channel: the robot has completed the replenishment of the gun, the electromagnetic pulse has been completed, the wall cavity has been penetrated, the high-voltage wires that have been found have been cut off, and the suspected dangerous items have been destroyed, and there have been several violent outbursts in the middle, but none of them threatened Liu Xiaolong who was lying outside the cave entrance; In the end, it was the turn of two items that were suspected to be time bombs.

If you are in a city, a time bomb will inevitably be de-endangered by EOD experts; But in the case of the suburbs, destruction is the most effective means.

Bang...... A violent explosion was made, even more violent than the explosion just now.

"Made, the two large explosives packets were connected and detonated together." Liu Xiaolong complained, the violent explosion produced a strong shock wave, and the dark red flames and explosion shock waves that rushed out of the small hole actually blew up Liu Xiaolong.

As a result, Liu Xiaolong, who couldn't borrow his strength in mid-air, suddenly fell into the hole.

"Let's go!" Liu Gang did not hesitate to withstand the shock wave of the explosion, and jumped into the cave below.

"Qin Fei, don't go down." Seeing that Qin Fei was about to make a move, Wan Qingshan stopped Qin Fei's "stupid" action, "The average height of the space below is 30 meters, and your mecha can only be a target." The heavy cavalry mechs themselves are not suitable for action in underground space.

You go to the southern location, and you just found the second passage, and you search south along the passage to see if you can block some people. Be careful, if the enemy is too strong, save your life first. Anyway, on Earth, the other party will definitely not be able to run! ”

"Yes!"

After Qin Fei received Wanqingshan's information, he turned around and ran like a south. However, after seeing that information, Qin Fei's mood was much lower when he was a little excited. I thought I could have a few powerful enemies to try my skills, after all, it was a waste to drive a steel monster like a heavy cavalry just as an excavator; But after carefully looking at the information, Qin Fei reluctantly found that the newly discovered passage was only about three meters, and it was actually four kilometers underground; If the thickness of the passage itself is removed, such a passage can barely be used as an emergency escape passage.

If it weren't for close-up and cutting-edge detection, such a small passage would not have been discovered at all!

Well, I'm a soldier now, obey orders!

With each running step, Qin Fei stepped on the ground and detected the situation underground through the mecha's own functions. Along the way, he hit countless trees, forced out of a passage in the jungle, and countless beasts fled.

One kilometer...... Ten kilometers ...... Thirty km ...... Not right!

Qin Fei is not a fool, if the emergency escape passage is definitely not so long!

50 km ...... 100 km ...... Qin Fei had been chasing for more than an hour, and he hadn't found the end of this passage yet. As a qualified warrior, Qin Fei reported the situation here as soon as possible, and at the same time, Qin Fei himself continued to chase south.

After chasing for two hundred kilometers, there is still no end, Qin Fei was suddenly shocked, I damn it, this passage will not be stabbed to the Bay of Bengal in one go!
