"Click-"

Replacing a magazine, Murphy crawled behind an overturned experimental table, and then stretched out the AGH rifle out of the table to shoot at the rushing Zerg outside, as for how high the hit rate is, it depends on the character. Caught in a bitter battle, Murphy felt a lot of pressure.

"Damn, I can't stand it like this......"

Previously, after the first round of attacks was blocked by Murphy alone, the Zerg temporarily stopped attacking, and then, they sent more poisonous blast insects to further widen the hole in the gate. This momentarily left Murphy at a loss, and when the hole was wide enough to pass through two wagons, the Zerg attacked again. Now, it became much more difficult for Murphy to defend himself.

So, Mo Fei took the initiative to take a back seat, tossing and turning between covers, and fired two shots from time to time. And the main task of defending against the attack of the Zerg is entrusted to a large number of automatic weapons. And the strong firepower output of the automatic weapon did not disappoint Murphy.

Faced with a dense charge of large dogs and stinging snakes, the 30mm grenade launcher gave them a blow to the head. After a round of intensive grenade bombardment, the Zerg who launched the charge were gone, and the remaining Zerg were either injured or disabled. The 12.7mm machine gun fired another round, and hundreds of attacking Zerg turned into corpses, and the farthest Zerg only entered the laboratory a little more than ten meters away.

The second round of attacks was blocked again, and the Zerg command was obviously mad, ordering the more than 300 Zerg waiting in the staircase passage outside the laboratory to rush up, including many high-threat Zerg such as Venom Monster and "Beetle Wolf". However, there were fewer such zergs and failed to cause fundamental damage to the defense network.

Whenever Venom wants to spray corrosive liquid to destroy a defensive weapon, some 45mm rivet launchers at the fire support point will give it a nail in time, and a half-meter-long barbed rivet will pierce the Venom monster's head and nail it to the ground. Even if Venom Monster's vitality is stronger than that of other Zerg, such a blow will still make it die quickly.

The rarer "beetle wolf" is dealt with by a 2000V high-energy stun gun. Whenever the "Beetle Wolf" appears and tries to perform a jump strike on the defensive weapon on the ceiling, the stun gun that has been charging for a long time will turn the muzzle of the gun to "electrotherapy" the "Beetle Wolf" in the air. The mutated carapace of the "Beetle Wolf" can withstand almost all the attacks of human light weapons, however, the conductivity of the carapace is surprisingly good, and the high-voltage current of 2000V hits it, directly electrifying part of the inside into a "paste pot", but from the outside, this "Beetle Wolf" seems to be fine.

At this time, it seems that there is nothing wrong with the laboratory's defenses, but then, big trouble comes.

"Shhhh

A new zerg clad in a tan carapace and shaped like a lizard suddenly rushed in through the gate. I saw them kick on the wall, and they actually fell directly to the ceiling, and launched a surprise attack from the blind spot of many automatic weapons. For a time, the automatic defense network of the laboratory was seriously damaged, and the Zerg on the ground took the opportunity to advance aggressively.

"Bastard! Die! ”

At the moment when a 12.7 automatic machine gun was destroyed by the Brown Lizard, Murphy threw a high-explosive grenade into the ceiling near the gate, and then raised his Kasumi shotgun and fired at it.

"Boom-"

The violent explosion completely destroyed the few remaining automatic weapons at the front of the defensive line, but most of the "brown lizards" that were maneuvering at high speed to evade the attack in those places were also eliminated, and there were no right units to hinder the shooting, and many automatic weapons in the center line opened fire at once, destroying all the "brown lizards" that launched the surprise attack. There is no ceiling. 、。 Under the cover of the Zerg, the hundreds of Zerg that were advancing on the ground were once again hit by the fierce fire of automatic weapons, and all the troops were annihilated.

The third round of attack was repulsed again, and Murphy had bought enough time that he was ready to retreat. However, Professor Constantine has not heard from him yet, and he plans to fight off the Zerg with the automatic weapon defense array for a while. And at this moment, the fourth round of the Zerg's terrifying attack began.

"Shhhh

"Squeak—"

Hundreds of Zerg roared and launched a suicidal charge, and many automatic weapons that received orders to destroy the enemy emerged from the ceiling mezzanine in unison, striking fiercely at the charging Zerg. In the rumbling explosion, the attacking Zerg suffered heavy casualties, but at this time, the mutation was abrupt.

"Whoosh-"

A turquoise orb flew into the lab at high speed through the hole in the door, crashed into an automatic machine gun, and then exploded.

"Bang-"

Murphy, who witnessed this scene, was taken aback and said in pieces: ", the poisonous explosion insect has turned into a cannonball?" ”

Not only did the shell destroy the automatic machine gun, but the corrosive fluid dispersed from the explosion also slightly damaged several nearby automatic weapons, and the shooting accuracy was slightly reduced. This "poison bomb" was just the beginning, and a few seconds after Murphy complained, several more "poison bomb shells" came in, several automatic weapons were destroyed, and the firepower of the defense was seriously reduced.

"Damn!"

Jumping out from behind the cover, Murphy's left hand AGH rifle and right hand Xia shotgun rushed to the side of the machine tool with a burst of indiscriminate fire, killing them all. Then, he threw himself directly to the ground, and a "poison shell" flew over his head at high speed, hitting a laboratory table behind him, and the entire laboratory table was blown up to the ceiling. If it weren't for the motion capture system, it would have been the first to find out

"Whoosh-whoosh-"

After discovering Murphy's human, the Zerg who used the "Poison Bomb Shell" diverted the fire output to the target, and one after another the Poison Explosion Worm was hit around the machine tool where Murphy was hiding, and the continuous blows almost turned the machine into scrap metal.

"Bastard, die!"

"Bang bang ————"

Murphy stretched his AGH rifle out of cover and fired in the direction of the "poison bomb", trying to attack the zerg. However, judging from the feedback from the Zerg's screams, it seems that only the stinging snake was hit.

"Click-"

So, after replacing a magazine, Murphy crawled behind an overturned experimental table, and then once again stretched out the AGH rifle from the table and fired at the rushing Zerg outside, causing some casualties to the Zerg, but it had little impact on the battle.

And there was no way to hit Murphy, and the Zerg that fired the "Poison Explosion Cannonball" also turned the target back to the automatic weapon that was easy to attack, and after a round of continuous fire, the defensive automatic weapon was reduced again, and the containment effect on the charging Zerg was becoming less and less obvious.

"Damn, I can't stand it like this......"

Leaning on the laboratory table, Mo Fei looked up at the smoke-filled ceiling, and for a moment there was nothing to do.

"Gunsmoke is right, it's smoke!"

Under the revelation of the gunsmoke, Murphy's head flashed, and he thought of a way to deal with the zerg.

Pulling two smoke grenades from his weapon bag, Murphy threw them towards the door, and in a few moments, a thick cloud of smoke enveloped the door of the laboratory.

"Whoosh-whoosh-"

Several "poison shells" flew in through the holes, but only one hit, and that one was still a "sideball", scraping the edge of a grenade launcher before exploding. The smoke had a huge effect on the Zerg's attack, and the rate of loss of automatic weapons dropped dramatically. Well, as for the problem that smoke affects the attack of automatic weapons against the zerg, it is basically negligible. Because these automatic weapons are equipped with infrared observation devices, they can still deliver precise strikes against the charging Zerg even if the smoke is blocked.

After successfully blocking the Zerg's attack for about a minute, Murphy finally waited for Professor Constantine's order.

"Whew, Murphy, Davey's injection is going to be done soon, you can take it down."

"Understood, I'll be back, over."

Removing several grenades and smoke grenades from his waist, Murphy threw them towards the door. The explosions and smoke both hindered the Zerg's attack and obscured their view, and Murphy escaped from the battlefield through the secret passage in the guard room. After a small trot, Murphy rushed to the chamber full of glass jars, just as Davey, who had completed the injection, had just left the lab bed and was putting on his armor.

"Oh my God, Mr. Davey, I'm surprised that you're still alive, haha-"

Seeing Mo Fei return unscathed, Dawei also smiled, and while sending his arms into the armor, he scolded with a smile: "Aren't you still alive, embarrassed to talk about me." Looking at your clean appearance, you shouldn't even touch the Zerg, I'm really afraid that things have reached the extreme. ”

Murphy waved his hand, not wanting to argue with Davey, "Go, go, we're going to have a big fight with the Zerg." Stop talking nonsense, hurry up and put on your armor, let's withdraw. ”

Putting his helmet on, Davey connected the team's radio and microphone, "Okay, everything is okay Professor, where are we going now?" ”

It was only then that Professor Constantine, who looked drowsy, lifted his glasses and pretended not to know and asked, "Well, what's wrong?" Did something happen? Don't you have to talk for a long time? Really, disturb the old man and I sleep. ”

"Professor!"

The professor frowned, his expression was very disgusted, "Anxious now?" It's good to be young now, come with me, the passage we escaped from is very hidden, unless the Zerg follow behind our ass, otherwise"

"Shhhh

"Squeak—"

Hearing the approaching sound of the Zerg's roar, Dawei couldn't help but complain, "Professor, you are the reincarnation of a crow!" ”

The professor picked up the briefcase on the laboratory table, spread his legs and ran away, "Don't talk nonsense, come with me!" ”

Davey and Murphy looked at each other and replied in unison, "Yes, sir." ”

Immediately, the two of them chased after the professor at a speed far beyond the professor's speed and set the professor up. And in order to escape as soon as possible, the unhappy professor had to show the way and let them run away
