Three months passed quickly.
The excavation operation is going very smoothly. More than 90% of a tunnel deep into the ground has been completed. Only the last short distance is left to open up the alien creature's underground lair.
The military is also making intensive preparations. The newly installed laser assault vehicles have been equipped in the hands of the teams that are about to go into the attack as the vanguard. In the past three months, they have figured out a set of methods of use and provided them with them. Relevant tactics were formulated.
Although this kind of laser assault vehicle is only equivalent to a heavy machine gun in terms of power, after it was actually put into use, the military concluded that laser weapons are much easier to use than heavy machine guns.
Compared with crane guns, which need to carry a large amount of ammunition and may cause ricochet and cause accidental damage during use, laser weapons completely avoid these shortcomings and can provide continuous and stable fire support for the troops, effectively suppress alien creatures, and greatly improve The combat effectiveness of the troops.
After all, a heavy machine gun can fire tens of thousands of bullets when used in an underground tunnel for one hour. Even if the accidental damage caused by ricochet is not taken into account, tens of thousands of bullets is still the amount that a truck is required to tow.
Now with laser weapons, this part of the ammunition consumption can be completely eliminated.
Satisfied 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 with assault vehicles, spider robots are obviously more suitable for tunnel environments. Originally, Chen Xin also provided the military with a model equipped with a heavy machine gun, and the military was very satisfied with its use.
However, compared to the current version equipped with laser weapons, 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, and the transformation of existing fire support spider robots is also more troublesome, and laser weapon modules must first be supplied to the production of assault vehicles, the military may want a large number of them. A spider robot equipped with laser weapons.
But three months was too short. Even if the factory worked hard to produce, the total number of laser weapons finally delivered to the troops was less than 200.
About one hundred of them are installed on assault vehicles, more than fifty are installed on spider robots, and the remaining dozens are used as replacements.
A dozen of these dozens of spare laser weapons were tentatively installed on the Bulldog Titan by some thoughtful technicians. After some testing, they also had good results.
With these laser weapons, the military cannot just wait and select the best troops among them. The military sends them into the underground tunnels that have been temporarily converted to defense to test these new weapons. The effectiveness of weapons.
It has to be said that laser weapons do have satisfactory effects. In military tests, the troops equipped with laser weapons completed the operation at a much higher speed than the original attack, clearing a tunnel very cleanly.
If the military had not planned to continue the attack and had them withdraw directly after the clearing, it is unlikely that this tunnel would have been captured just like that.
This is undoubtedly much more efficient than the previous time when the military had to go back and forth with extraterrestrial creatures very laboriously.
This undoubtedly greatly boosted the morale of the military and gave them more confidence in the counterattack plan. If they could continue to eliminate underground creatures with such efficiency, the military even felt that they did not need to rely on the excavation plan. Eliminate the alien creatures underground in the Dongting Lake area within a month.
Of course, the premise is that the alien creatures have nothing else to do with them.
But things are often expected. According to Murphy's theorem, if something bad is going to happen, it will definitely happen. With only the last short distance left in the excavation operation, the construction team expanded the tunnel according to the original plan. When building an advance base, an accident happened.
——————————————
During the tunnel excavation process, detectors are always monitoring the strata around the tunnel to prevent the possibility of drilling through an underground tunnel or cave during the excavation process.
At the same time, we are monitoring the activities of alien creatures in the surrounding tunnels and caves to prevent them from digging tunnels and interfering with the construction.
The previous excavation work had been smooth. Relying on a route determined by geological survey that completely avoided the existing underground tunnels and caves, no interference from alien creatures was encountered during the tunnel excavation construction process.
But when there was only less than a hundred meters of tunnel excavation left, and the construction team had begun to expand the tunnel into an advance base, the surrounding alien creatures suddenly all moved towards the tunnel excavation position like crazy. Drilling a hole, he looked like he was determined to dig through this place.
This undoubtedly triggered an alarm. The construction team adopted an emergency plan and hurriedly evacuated all the workers. At the same time, in order to protect the precious shield machine, they also disassembled it as quickly as possible and evacuated it from the underground together with the evacuated workers. come out
It took three months to dig in, but less than half a day to exit.
After the construction team evacuated, the military quickly entered the tunnel and prepared for battle based on the detected alien biological activities.
When the first worker ant dug through the wall of the tunnel and emerged from it, a laser invisible to the naked eye shone on its head instantly, and then exploded it into a knocked-out shell in less than a second. Rotten watermelon.
Immediately, more alien creatures poured into the tunnel and began to attack upwards.
However, humans have long been prepared. With the help of the fire control system, dozens of laser weapons continued to shoot at these alien creatures. Almost instantly, the tunnel was filled with corpses of alien creatures, even causing the alien creatures to tremble. The offensive was affected.
But these alien creatures did not stop, but continued to dig out the tunnel completely at the risk of huge casualties, allowing more combat larvae and worker ant larvae to pour into the tunnel.
Because the tunnel is almost a straight line, humans naturally no longer have the limitation of being unable to take advantage of weapons when fighting in underground tunnels due to the winding terrain. While the newly equipped laser weapons are showing their power, heavy machine guns and The light cannon is not far behind, spraying large amounts of ammunition while bringing death to the alien creatures.
However, out of concern that the tunnel would collapse, the military did not use large-caliber artillery or powerful explosives.
The Yan Kingdom's military counterattack against the underground alien creature's nest in the Dongting Lake area began in a situation that the humans did not expect but were prepared for.
