The two mercenaries who had not had time to retreat were completely trapped on the outer wall. Lin Song watched these two people, frantically raising his gun to shoot at the living dead who were coming around, at the beginning, they were able to barely repel the attack of those living dead, but soon they were already a little unable to hold on.

They were in a hurry on Qiandong Road, and hurriedly used *** to help snipe. But after all, there is an upper limit to the rate of fire of ***, Qian Donglu and Zhang Feiyu have two guns, even if they tire the two of them to death, there is no way to rely on two people and two guns to block so many living dead.

In the end, even the two mercenaries above had run out of bullets, and Qian Donglu was still nervously pulling the bolt, so Lin Song could only put his hand on the barrel of Qian Donglu: "Okay, it's useless." ”

Qian Donglu slowly raised his head, and Lin Song shook his head: "You can't save them, don't waste bullets." ”

Qian Donglu took a deep breath, looked at the two desperate mercenaries on the half wall in front of him, and cried like two children, clenching his teeth.

In fact, everyone knows very well that what Lin Song said is right, now the living dead have begun to press the second line of defense of the Ark base, the air passage in the middle has been cut off, and they themselves have run out of ammunition, even if the people of the entire defense line behind use firepower to cover them, there is no way for the two of them to run back.

The blame was that they left too late, and the teammates in front of them walked too quickly, crushing their only escape route. This is a battlefield of life and death, and the laws on the battlefield are so cruel, if you make a mistake, you will have to pay the price of your life, and no one can replace it.

In the end, the two mercenaries screamed and were dragged down by the living dead who climbed up, Lin Song directly snatched the *** in Qian Donglu's hand, raised his gun to aim and shoot in one go, and with a snap, it hit one of the mercenaries directly on the head.

The mercenary's head blossomed on the spot, and at this time Zhang Feiyu also understood that the most important thing now was nothing else, or to give these two mercenaries a good time.

Zhang Feiyu followed Lin Song's example, and also raised his gun to aim and shoot, and the life of the second mercenary was also ended. It's just that in this way, those living dead who were originally going to bite them actually stopped, as if they were a little disappointed that these two living beings suddenly turned into two lifeless corpses.

That's right, these living dead also want to torture the living, not to toss the two corpses, they are happy to leave these two corpses, and look at the second line of defense here with more resentful and vicious eyes.

Lin Song had already told Wood and the others to find a way to strengthen the second line of defense, and now the entire defense line was stronger than before, those living dead rushed up and directly loaded it on top of the iron thistles covered with spikes, and soon, those iron thistles were covered with all kinds of flesh and blood with a peculiar smell, which looked bloody and shocking.

Lin Song and the others were organizing manpower to start firing back, and they still used guns at the beginning, but soon Lin Song realized that the ammunition reserves in the Ark base were not very sufficient.

"How much ammo is left?" Lin Song asked, pulling Wood.

Wood paused for a moment, shook his head and said, "I...... I don't know, but it's all taken from the police station's ammunition depot, that's all. ”

As Wood spoke, he pointed to the dozen or so wooden boxes next to him and said, Lin Song and the others were all professional special forces, and they just took a look at it and calculated an account in their hearts.

If you follow such ammunition reserves, you can only get less than a hundred rounds of ammunition per gun on average!

In Huaxia, when an ordinary soldier is engaged in combat, the ammunition base is 300 rounds, and in the case of ordinary combat frequency, these 300 rounds of ammunition can only support the soldier for less than three days.

In other words, according to the current style of play, these bullets will not last even a day.

Lin Song gritted his teeth and shouted; "Find a way to save bullets! If you can use bullets, you don't need bullets! ”

Saying that, Lin Song set an example, directly picked up a dismantled steel water pipe from the side, a section of the water pipe was broken, and the stubble was very sharp.

The water pipe stabbed directly into the eyes of a living dead, Lin Song felt that his water pipe was stuck by the other party's bone seam, this feeling was honestly very uncomfortable, but Lin Song had no choice, he could only grit his teeth and pull out the water pipe, who knew that this pull, even half of the eyeball in the other party's eye socket was directly brought out.

Lin Song took a deep breath: "Try to use cold weapons!" We have a limited number of bullets, and we have to save them for the final breakout. ”

The people behind responded to Lin Song one after another, but soon, everyone realized that the cold weapon seemed to be very easy to use and very happy, but when they really used it, they found that the best thing to use was the gun.

Those who have not been trained in real systematic assassination, when they use bayonets or steel pipes, steel bars and the like to fight the living dead, often do not wait for the living dead to be injured, but hurt themselves. Even if they can stab the living dead, when they pull out their weapons, they are still dragging mud and water, and some people even accidentally grabbed them directly by the other party when they pulled out the steel bars, and bit off two fingers with one bite.

At this moment, a voice came from the southwest, and someone shouted: "The workshop wall in the southwest has collapsed, and the second line of defense can't stop it!" ”

"Get all our people out!" Lin Song shouted: "Find someone to go up directly and close the door of the workshop, the workshops here are all big iron gates, and those living dead are not so easy to break in." ”

Lin Song's second line of defense is composed of dense factories and narrow intersections, the advantage of these places is that they can fight and retreat, once they are broken through by the other side, they can be cut in time, just like the sealed door on a ship, once there is water in the cabin, closing the hatch can prevent seawater from pouring into the entire cabin.

Soon, the superiority of Lin Song's tactics was reflected, and the people of the second line of defense quickly completed the 'cutting' and reorganized the defense line.

But at this time, Lin Song had already seen that according to the opponent's offensive intensity, the second line of defense would not last long. And the most dangerous thing now is that there are not many people who can come out and fight.

Originally, the men in the Ark base could be called all soldiers, but actual combat proved that many people were not as good as being a deserter on the battlefield. There are so few people involved in the defense right now!
