"Can't stop it, retreat!"

"Puff puff!" Lao He used up a box of energy bullets, reached out and touched his waist, and found that the magazine was empty.

"Resist me, behind us are tens of thousands of ordinary people, including our compatriots, brothers and sisters, if we hold on for one more minute, we will have more hope for life!"

"But we have no ammunition, should we fight the dark creatures with our bare hands?" said one soldier, running out of ammunition and throwing his gun away.

"Stop!" Lao He put his empty gun on the head of the deserter, and said with a murderous face: "Who dares to take a step back, I know you, but the gun in my hand doesn't know you, and if you dare to retreat lightly, kill!"

Shrimp holding the M99 semi-automatic sniper rifle, a black-toothed mantis in the scope, the black-toothed mantis is still the first time to appear on the battlefield, when it first appeared from the invasion port, it was a black shelled meat ball, if you don't look carefully, you think it is an explosive insect, and when the meat ball is all unfolded, you can see a dark and slender body, waving two one-meter-long limb blades, like a black warrior holding a double knife is terrifying.

Unlike the previous invasion of the underground base by dark creatures, this time the dark creatures sent an unprecedentedly powerful lineup, not only many dark creatures have never heard of, but even the level of cannon fodder has increased a lot, the first and second orders are already difficult to see, the third and fourth order dark creatures are running around the base, and the rare fifth and sixth order dark creatures grab a handful.

It is simply difficult for ordinary guns in the hands of soldiers to kill third- and fourth-order dark creatures, and with the appearance of a tide of dark creatures for a while, they are even more panicked and out of level, and their combat level has dropped by more than one percent.

"Bang!" the sniper rifle in Shrimp's hand rang out, and a fourth-order black-toothed mantis waved its limb blade, the sharp limb blade was like a toothed machete, slashing through the waist of a soldier, and the soldier didn't even feel the pain, he found that his upper body was flying ahead, while the lower body had staggered and fell to the ground, and the front end of the black-toothed mantis's triangular flat head was torn out with two front chelas At this moment, a specially processed sniper bullet penetrated the head of the black-toothed mantis, the pale green liquid splashed everywhere, and the two sharp limb blades danced wildly, "Boom, boom" The two knives slashed at the two black-winged beasts around him, struggled a few times, and fell to the ground with a "plop".

"Why don't you use a sniper-like energy gathering gun, if you're worried that the energy magazine won't be used, just borrow me a few", Lao He kicked the shrimp who was squatting behind the cover.

Shrimp grinned and said: "You should always save your worries, aren't I worried that the energy magazine is not enough? It is enough to deal with the M99 semi-automatic sniper rifle of dark creatures below the fourth order, and the sniper-type shaped gun has to be used at a critical time, I don't see it, you still like to take advantage of our juniors."

Lao He didn't have time to play with shrimp, "Go and find more ammunition, just dismantle everything that can be burned for me, and then ask Lu Ziming, can you add a little more soldiers to us here?"

Shrimp blinked his eyes, approached Lao He and said: "Lao He, this is not a way, there are too many dark creatures, and you can't kill them all, let's find a way! Otherwise, I can't stand death, I'm not afraid of death, but I don't want to die in the mouth of the dark creatures! I think push the Gauss machine gun over, maybe we can hold it up for a while!"

Lao He's eyes widened with anger, he only had 100 Chiyou Space Guards under his command, and he finally gathered five or six hundred scattered soldiers, and it was no longer enough to defend the four main passages.

"No, I want to use the Gauss machine gun after only an hour, so what about the next five hours!" Lao He Ke is a standard soldier, and the order said that if he holds on for 6 hours, he will definitely hold on for 6 hours, and not a minute will be missing, this is a promise made with blood and will.

Lu Ziming never thought that he could repel the attack of dark creatures from the beginning, and it was best to buy a day of retreat time for ordinary people in the base, no! At least 6 hours of evacuation time should be guaranteed, which is already the limit of the evacuation of most people in the base. Zixin has deduced in detail that if a qiē shun lì, in an orderly 6-hour evacuation time, the base can evacuate more than 7 percent of ordinary people, within 10 hours can evacuate all ordinary people in the base, and the remaining time will be emptied as much as possible of all the materials that can be used, which will take about 10 hours, but this qiē is a theoretical deduction, and it is very different from the actual situation.

First of all, panic and panic caused a large number of people to crowd at the entrance of the Chiyou space, and the collapse accident kept happening, and the evacuation work was slow. The dazed crowd was scurrying around in the base, although a notice had been issued, but there were still many people who stayed in place, and Lu Ziming had to organize a large number of people to check in each layer of the base, which consumed a lot of time.

Secondly, the dark creatures have been hiding their strength, and at the beginning of the attack, they quickly advanced to several transportation hubs regardless of casualties, which also created a great obstacle to the evacuation work.

In the end, the base had just undergone an accident, a large number of soldiers were scattered everywhere, and no effective battle group was formed, and these soldiers were temporarily integrated together without command, but they cooperated with each other very poorly, and their combat effectiveness and will to fight were reduced to a terrifying level.

Of course, these are only one of the reasons, but the main thing is that the dark creatures launched an unprecedented invasion, if the current dark creatures invasion combat power is set at 100, then the previous dark creatures invasion combat power is only 30-40, between the advantages of the other, the shape of the base is even more precarious.

Shrimp pouted and turned around and left, knowing that the role of staying here was not great, the internal structure of the underground base was too messy, and the longest passage was no more than a kilometer, and most of the passages were about 100 meters, which required high requirements for sniper channel operations, and it was difficult to play the effect of a sniper.

"Give me a grenade, blow up these dark creatures", Dashan **** crossed his arms, his upper body was only covered with a mutant turtle shell zuò armor, and he held an iron rod that was like a red burning in his hand, and jumped up and smashed it towards a silver-gray mutant spider in front of him.

This is a fifth-order ghost-faced tarantula, with 8 huge compound eyes neatly arranged above the cheeks, flashing with a bright light, which has a hypnotic effect. As long as you are targeted by the ghost-faced tarantula, there will be a sense of powerlessness in your body, as if the whole person is stuck in a muddy swamp, and in a trance, you will drop your weapon and walk towards the ghost-faced spider uncontrollably.

Just now, a spider web protruded from the mouthparts of the ghost-faced spider, covering a soldier in the spider web, and dragged him into the spider pile.
