Doomsday Bunker Upgrade Chapter 702: The counterattack begins

Three months went by so fast.

The excavation operation is going very smoothly. A tunnel deep into the ground has been completed more than 90%, and only the last short distance is left to get through the alien creature's underground lair.

And the military is also making preparations. The latest laser assault vehicle has been equipped in the hands of the team that is about to go into the attack as the vanguard. In the past three months, a set of usage methods has been explored. and developed strategies for it.

Although this laser assault vehicle is only equivalent to a heavy machine gun in power, after it was actually put into use, the military came to the conclusion that the laser weapon was much more useful than a heavy machine gun.

Compared with crane guns, which need to carry a lot of ammunition and may cause accidental injuries due to ricochet during use, laser weapons completely avoid these shortcomings and can provide troops with continuous and stable fire support, effectively suppressing alien creatures, Greatly improved the combat efficiency of the troops.

After all, a heavy machine gun can shoot tens of thousands of bullets in an underground tunnel for an hour. Even if the accidental injury caused by the ricochet is not considered, tens of thousands of bullets are still the amount that a truck needs to tow.

Now with laser weapons, this part of the ammo consumption can be completely removed.

Because of the satisfaction with the laser weapon, the military even tried to install it on the spider robot that Chen Xin had previously provided to the military.

Compared to assault vehicles, spider robots are obviously more suitable for the tunnel environment. Originally, Chen Xin also provided the military with a model equipped with a heavy machine gun, and the military was very satisfied with it.

But compared to the current version with the laser weapon, the original heavy machine gun version is naturally less attractive.

If it weren't for the fact that the production of spider robots is more complicated and time-consuming than that of assault vehicles, the transformation of existing fire support spider robots would be more troublesome, and the laser weapon module must be supplied to the production of assault vehicles first. The military may prefer Want a lot of spider robots equipped with laser weapons.

But three months is really too short. Even if the factory worked hard, the total number of laser weapons delivered to the troops was less than 200.

About one hundred of them were installed on assault vehicles, more than fifty were installed on spider robots, and the remaining dozens were used as spares for replacement.

Among the dozens of spare laser weapons, more than a dozen of them have been tried and installed on the Duke Titan by some thoughtful technicians. After some tests, they also have good results.

With these laser weapons, the military can't just wait like this, select the best troops from among them, and send them into the underground tunnels that have been temporarily turned into defense. Test out the use of these new weapons.

I have to say that laser weapons do have a satisfactory effect. In the military's test, the troops formed with laser weapons completed the operation at a much higher speed than the original attack, and cleared a tunnel very neatly. .

If it wasn't for the fact that the military didn't plan to continue the offensive and let them withdraw directly after the clearing, it is impossible to say that this tunnel would have been taken down just like that.

This is undoubtedly much more efficient compared to the previous time when the military had to repeatedly see and see with alien creatures.

This has undoubtedly greatly boosted the morale of the military and gave them more confidence in the counter-offensive plan. If they can keep clearing the underground creatures with such efficiency, the military even thinks that they don't need to rely on the excavation plan. Be sure to eradicate the alien life in the Dongting Lake area within six months.

Assuming, of course, that the alien creatures have nothing else to do.

But things are often expected. According to Murphy's theorem, if a bad thing is about to happen, it will happen. With only the last short distance left in the excavation operation, the construction team carried out the tunnel according to the original plan. When it was time to expand to build an advance base, an accident happened.

——————————————

During the tunneling process, there are always detectors monitoring the strata around the tunnel to prevent the possibility of penetrating an underground tunnel or cave during the tunneling process.

At the same time, it is monitoring the activities of alien creatures in the surrounding tunnels and caves, so as to avoid being dug through tunnels by them and disturbing the construction.

The excavation work has been very smooth before. A route that completely avoided the existing underground tunnels and caves was determined by geological exploration. During the construction of the tunnel, there was no interference from alien creatures.

However, when the tunnel was less than 100 meters away, and the construction team had already started to expand the tunnel into a forward base, the alien creatures around them suddenly all headed towards the tunnel like crazy. The position is frantically punching a hole, with an aura that promises to dig through it.

This undoubtedly triggered the alarm. The construction team took an emergency plan and evacuated all the workers in a hurry. At the same time, in order to protect the precious shield machine, it also disassembled it in the shortest time, and together with the evacuated workers, Withdrawn from the ground

It took three months to dig, but less than half a day to quit.

After the construction team was evacuated, the army quickly entered the tunnel and prepared for battle according to the detected alien activity.

When the first worker ant burrowed through the wall of the tunnel and emerged from it, a laser invisible to the naked eye instantly irradiated its head~IndoMTL.com~ and then in less than a second It fried into a battered watermelon.

Immediately, more alien creatures poured into the tunnel and began to attack upward.

However, human beings have already made preparations. With the help of the fire control system, dozens of laser weapons are constantly shooting these alien creatures. The offensive of the star creatures was affected.

But these alien creatures did not stop, but kept digging the tunnel completely at the risk of huge casualties, allowing more fighting offspring and worker ants to pour into the tunnel.

Because the tunnel is almost a straight line, human beings naturally no longer have the limitation of being limited by the curved terrain and unable to exert their weapon advantages when fighting in underground tunnels. Heavy machine guns and light machine guns are not far behind, swaying a lot of ammunition while sending death to alien creatures.

However, out of fear of collapsing the tunnel, the military did not use large-caliber artillery and powerful explosives.

The battle of the Yan Kingdom's army to counterattack the underground alien creature nests in the Dongting Lake area began in such a way that the human side did not expect it, but was well prepared.
