Now that it has been exposed, Qi Lin has no scruples, and directly took out the Bison submachine gun from his backpack and crashed out of the gate of the machine room.

"Knock knock!!"

"Knock knock!!"

There were already three soldiers guarding the door of the computer room, and when they saw Qi Lin coming out of the machine room, they even shot at him fiercely!

It's just that Qi Lin rolled on the spot, dodged those deadly bullets, jumped up on the floor with his left hand, held the Bison submachine gun with one hand in his right hand, and swept over with a shuttle with his backhand-

"Tutu Tutu Tu—"

The three soldiers were immediately shot and fell to the ground, and Qi Lin's strafing shot avoided the body armor and helmets on their bodies, directly sweeping their faces into a bloody blur.

A nine-millimeter Parabellum shot in the face may not be fatal, but what if it is ten?

The three soldiers had almost their entire faces smashed, and some of the bullets even burst into their eyeballs, burrowing into their brains through their sockets.

These three soldiers should be guarding outside this machine room, so Qi Lin bumped into them as soon as he went out, and it was estimated that it would not be long before the troops stationed in the Xuanwu shell would arrive here.

Qi Lin ran to the bodies of the three soldiers and picked up their guns and magazines - the soldiers in the internal guard were using a large-caliber assault rifle called the "AR2040", as the name suggests, this is a new assault rifle of the AR gun family finalized in 2040, which is based on the famous "AR-15" assault rifle designed by Eugene Stoner.

But what's interesting is that as the ancestor of the world's small-caliber assault rifle, AR-15's latest descendant - "AR2040" is back in the ranks of large-caliber, AR2040 uses the latest ten-millimeter caliber full-power rifle cartridge, although the magazine is shortened to only 15 rounds, but the power is close to the use of point 50 BMG large-caliber heavy machine guns, and in terms of range and accuracy is not inferior to the vast majority of sniper rifles before the war.

But the only problem, and also a common problem with 10 mm caliber full-power assault rifles, is that the recoil is too great.

Heavy machine guns tend to have a stable mount, while sniper rifles are rarely capable of fully automatic fire, and as an assault rifle, the AR2040 was originally designed for use with the Evolver Soldier as a target audience.

In the old era, only a fighting nation like Maozi would design a large-caliber full-power assault rifle, but whether it was 6p62 or Ash-12.7, these two large-caliber assault rifles were not mass-produced in the end, let alone assembled into the army.

But now the times are different, the enemies of humanity are no longer limited to the same kind, and many thick-skinned mutant creatures cannot do the ideal damage with the 5.56, 5.8, or even 7.62 mm guns of the old era, so the proposal to install a new large-caliber rifle has been listed by various consortia.

However, in order to control the large-caliber assault rifle, the shooter must have an extraordinary physique, even if he is not an evolutionary, he must look like a brute bull - and it is for this reason that the three soldiers were unable to hold down the muzzle of the AR2040, which allowed Qi Lin to dodge all the bullets with a single roll.

The AR2040 assault rifle has not been installed in the army for a long time, and the number of live-fire training is only a few times, if these three soldiers are used to this weapon with extremely terrifying recoil, I am afraid that the current outcome will not be like this.

However, if these three soldiers can't control the AR2040, it doesn't mean that Qi Lin can't control it, with the strength of a second-level evolutionary, he can even shoot left and right and use two AR2040s to strafe at the same time.

Taking advantage of the fact that the garrison troops in the Xuanwu shell had not yet arrived, Qi Lin carried these rifles on his back and quickly climbed onto the roof of the machine room - here the field of vision is wide, and it is easy to suppress the fire below, and the buildings near the machine room are all of the same height and not far apart, Qi Lin has a number of follow-up routes to choose from.

As soon as Qi Lin climbed onto the roof, a group of soldiers wearing gray uniforms and black bulletproof vests ran over, and as soon as they saw three corpses lying on the ground, they scattered to find cover, but at this time, Qi Lin pulled the trigger on the soldiers below-

"Knock Knock Knock ——!!"

The sound of the AR2040's gunfire was as muffled as thunder, and the large-caliber full-power rifle bullets that came out completely ignored the body armor on the soldiers' bodies, tearing the fragile flesh one after another, and it was just the first strafing shot, Qi Lin killed six people, including the second lieutenant who led the team.

"The intruder is on the roof!"

"Fire suppression!"

The remaining soldiers did not lose their position because of the death of the officer, but quickly locked on Qi Lin's position, and the same dull but more than ten times denser gunfire rang out below, and the barrage completely covered the edge of the roof, making it completely impossible for Qi Lin to poke his head out to fight back.

"It's a pity there are no grenades."

Qi Lin shook his head and ran in the opposite direction - these soldiers are very experienced, at least much stronger than the three guys guarding the door of the machine room, in addition to the recoil of large-caliber assault rifles, the endurance is also a big problem, and the fifteen-round magazine often misses in a few short shots, but not all of these soldiers shoot at the same time, when some people fire, the other part just aimed at the roof and did not pull the trigger.

In this way, if the magazines of the first batch of soldiers were empty, and Qi Lin wanted to take advantage of the time to reload to shoot back, those soldiers who had never fired would quickly pull the trigger.

"Alternate fire suppression" is a compulsory course for a qualified soldier, but at present, these people have obviously mastered this skill to the point of perfection, and the cooperation is also a first-class tacit understanding, almost no superfluous communication is required, and only the thunderous roar of AR2040 is in their ears.

To be honest, these soldiers were the most combat-qualified troops Qi Lin had encountered in the Vault, and presumably these people had not only undergone a lot of training in reality, but also experienced a lot of actual combat training in the virtual wasteland game world.

If you are not careful in fighting such an opponent, you will fall into a desperate situation of certain death.

Therefore, Qi Lin decided to avoid its edge for the time being, anyway, his original plan was not to kill all these troops stationed in the Xuanwu shell, his goal was only the commander of this army.

That Cheng Su's adopted daughter - Cheng Mu.

The control center building located in the middle of the basalt shell, Qi Lin had already noticed, it was the most heavily defended place in the entire No. 1 energy reactor, and it was also the most likely place for Cheng Mu to be.
