At dawn, the infrasonic cannons blocking the entrance to the enemy nest gradually stopped, and after more than an hour of almost paranoid bombardment of the enemy nest, the infrasonic waves that swept across the battlefield dissipated.

If it weren't for the fact that the armored vehicles were about to run out of fuel, it was uncertain whether Chi Wei would have ordered a ceasefire.

Opening the car door, Chi Wei jumped out of the armored car.

There was silence outside the car, a silent silence that made one want to make a little noise.

Chi Wei looked around, took a few more random steps, and then ordered the troops to release the drone.

A swarm of mechanical spiders immediately climbed out of the armored vehicle and quickly burrowed into the enemy's lair...... The production capacity of mechanical insects is too small, and the needs of the special service group must be met first before they can be supplied to other troops, and the number is not guaranteed.

At present, the vast majority of troops are equipped with UAVs that are still mechanical spiders and unmanned rotorcraft.

However, mechanical spiders also have advantages, that is, the power of transmitting signals is relatively high, and the signal relay that insect drones must have dozens or hundreds to complete, only a dozen or so are required for mechanical spiders at most.

A group of mechanical spiders rushed into the enemy's nest at a rapid speed, advancing all the way to the depths of the enemy's nest, and not far into the hole, they encountered a giant insect that had died a dozen years ago.

The mechanical spider crawled up and down quickly between the corpse of the giant insect and the ground, and continued to advance to the depths of the enemy nest, the deeper it went into the enemy nest, the more insect corpses encountered on the way, and in the most serious section, the crowded insect corpses even blocked the hole in the ground, and the mechanical spider tried its best, but could not find a gap that could be used!

Chi Wei soon saw this scene, but he didn't understand what method the insects used to fill the hole so much before they died.

However, the mechanical spider in the other direction quickly found the answer, and the hole in that direction was also blocked by insect corpses, but the blockage was not so tight, and the mechanical spider took a lot of effort to drill through, and then found a heavy giant insect behind the piled insect corpses!

The so-called heavy giant insects refer to those insects with particularly large bodies and thick carapaces, and are a general term for a type of giant insects, rather than a single type of giant insects.

At present, humans have not been exposed to many heavy giant insects, and only heavy light insects and heavy beetles have been registered in taxonomy, of which there is only one kind of heavy light worm, but there are several kinds of heavy beetles.

The largest heavy beetle is the kind that the special service team encountered in the desert, and it has been officially named the desert beetle, but that thing has no combat effectiveness at all, and it is purely for decoration.

The one with a little worse body size was the car insect that appeared for the first time in Maple City, that thing could carry several servants, and its height was comparable to that of a desert beetle, but its body was shorter, so it had to be relegated to second place.

Some of the remaining heavy giant insects are good at digging, some are simply meat shields, and some are just short-lived, and it is unclear what they are capable of.

The heavy giant insect in the enemy's nest is a nameless giant worm, although I don't know what kind of ability it has, but when I see the situation in the cave, no matter how stupid my brain is, I know that the wall of insect corpses blocking the passage must have been piled up by this thing!

Chi Wei also thought of this answer, but he couldn't figure out how long this thing had to hold on in the infrasonic tide of magic sound to pile up so many giant insect corpses.

Regardless, the thing was eventually killed by infrasound.

At this moment, Chi Wei was extremely glad for his persistence, if the time of the infrasonic bombardment was short, it was really hard to say whether he could shock this giant insect to death!

Chi Wei is far more fortunate than he is alone, Beidu, Beiyuezhou, and all the high-ranking officials who are qualified to see this video are all secretly relieved in their hearts.

After the incident, the military held several meetings specifically for this matter, and it was unanimously agreed that there are too many types of giant insects, and the effect of infrasound waves on aliens is very strong, but the lethality of giant insects is not clear, so in future combat operations, it is necessary to extend the action time of infrasound waves to avoid leaving live insects.

The specific time is tentatively set for one and a half hours with reference to the operation in southern Xinjiang.

The mechanical spider continued to go deeper, but everyone's hearts were clouded - since the giant worm could hold out for so long, would there still be any live worms left in the hole?

It's hard for Chi Wei to imagine what kind of insect can last so long in infrasound.

More and more images were sent back by spiders, and more and more insects were encountered, and holes were blocked with insect corpses more and more frequently, but no trace of live insects was ever found.

The mechanical spider was about a kilometer underground, encountered the corpse of the first insect man, and continued to go deep into the enemy's nest, the spider found more and more insect corpses, first the corpse of the insect man and the corpse of the giant insect were mixed together, and it didn't take long for the corpse of the servant soldier to be found, all kinds of corpses were all over the enemy nest, to put it simply, the giant insect died, the insect man died, and the servant soldier also died.

After the mechanical spider arrives in the core area, Chi Wei is delighted to find that the aliens are also dead.

And that's not all, a nest of shattered eggs was found near the core...... A nest of eggs is just a habitual saying, a whole hole to be exact!

This was so unexpected that no one would have thought that infrasonic could shatter all the eggs.

Manipulating the mechanical spider closer, the eggs in the camera not only shattered their shells, but also mixed up with the remaining liquid in the eggshells...... Chi Wei didn't know what the structure of the eggs was, but the eggs were much the same, nothing more than the embryo plus the nutrients that supplied the embryo for growth, even if it was not an egg white and egg yolk, it was a similar structure.

It was clear that the liquid inside had been shattered by infrasonic waves before the eggs were broken.

Chi Wei thought about it, and he couldn't think of anything in the worm egg that could resonate with infrasound, but what about him? Whether it is a giant worm, a worm man, or a servant, all those in the enemy's nest are all killed and wounded in the infrasonic fire that does not leave dead ends, and this is the most satisfactory result of the operation.

As for why there is left in the enemy's nest, let the research person worry about it!

After determining the situation in the enemy's nest, it was already three poles in the morning, and Chi Wei used a small robot to send a nuclear bomb into the core area of the enemy's nest according to the order of his superiors, and then ordered to evacuate.

The scale of the enemy's nest was huge, and in order to destroy the enemy's nest in one fell swoop, the nuclear bomb yield sent into the enemy's nest was extremely high, and in order to withdraw the dangerous vehicles as soon as possible, the convoy withdrew as fast as possible, and passed through the border after more than two hours.

It was only at this time that the military issued the order to detonate, and the nuclear bomb in the enemy's nest exploded suddenly, and the nuclear explosion area was like a major earthquake, and the land collapsed and cracked in an instant.

The seismic waves spread rapidly, and soon after, the seismic waves caused by nuclear explosions were detected by all the seismic monitoring stations in various countries, and the world's attention quickly focused on Southeast Asia.
