Song Yichen, who discovered this, immediately sent for Song Yi and Zhang Fei. When Song Yi and Zhang Fei came to the front defensive position, song Yichen directly handed the two telescopes to Song Yi and Zhang Fei respectively.


    "The situation is not good. The mutant zombies in the distance began to mutate twice after hunting other zombies. Have a look with your own eyes"


    After hearing this, Song Yi and Zhang Fei hurriedly looked ahead with the military telescope song Yichen handed over. Unfortunately, the mutant zombie with two additional arms grew slowly. Once they killed the ordinary zombie around them, and then began to eat the brain of the zombie. Then the additional two arms, which were only 30 cm long, began to grow slowly again.


    Song Yi and Zhang Fei, who witnessed all this with their own eyes, have different expressions. Song Yi''s expression is a little serious, while Zhang Fei''s words are unbelievable.


    "It seems that this matter must be reported to the head, so that the head can prepare early."


    "Darling, what kind of monster did I see? I just don''t know whether this thing can fight or not"


    Their different reactions also show their different personalities.


    Just after they have just observed the opposite corpse group, the distance between the defensive position and the distant corpse group is less than one kilometer, and the corpse group will soon find the soldiers in the defensive position and launch a raid.


    At that time, it will be a battle in which either you die or I live. Since Song Yi saw the second variant zombie, he immediately mobilized the infantry vehicles on standby in the rear through the walkie talkie to support him.


    "All infantry chariots! Go to the defense position ahead immediately and help the soldiers defend together! Come on!"


    "Copy that!"


    Soon, the infantry vehicle, which had been stationed in the rear with other trucks of the team, drove to the front of the defensive position. The driver of the infantry vehicle directly saw the corpses not far away through the observation window.


    At this time, the corpses also heard the noise caused by the engine of the infantry chariot through their keen hearing. The brush time was still walking slowly. Even the ordinary zombies who were indifferent to being attacked by the mutant zombies seemed to have regained their rebirth and looked at the direction of the infantry chariot.


    Then it began to riot. All ordinary zombies frantically took their own steps and ran like crazy to the defensive position where the infantry chariot was located. Their speed was no less than that of the general sprint champion.


    Even the mutant zombies, who are bent on eating the brains of ordinary zombies, seem to have encountered some delicacies. They directly left the ordinary zombies and ran crazy to the defense position. Their speed directly threw away the ordinary zombies. We can imagine how fast these mutant zombies are.


    The soldiers in the defensive positions are not vegetarians. They are not ordinary people. If ordinary survivors see the running zombies, they will be a little overwhelmed, but as clones specially exchanged as soldiers, they will not be afraid.


    All clone soldiers are waiting for song Yichen''s firing order. Even if these zombies run so fast, they don''t feel the slightest fear. Instead, they calmly look at the zombies in the distance and wait for the firing order, as do the infantry chariots.


    Finally, after the first mutated zombie entered the defense position 400 meters away, song Yichen ordered to fire.


    "Everyone! Aim at the target and attack freely!"


    "Infantry chariot! Aim at the mutant zombie and concentrate your fire!"


    Song Yichen and Song Yi''s orders were issued almost at the same time, and the whole defensive position was no longer silent under the orders of these two people. Suddenly, the whole defensive position was covered up by the sound of guns and guns. Heavy machine guns, rifles and Gatling machine guns all sent out deadly flames in an instant.


    The zombie group that launched an attack on the defensive position encountered a dense array composed of countless bullets at the first time. First, the first batch of the fastest variant zombies. More than a dozen variant zombies lined up in two rows to attack the defensive position. In the first row, there was only one variant zombie, that is, the four arm variant zombie of secondary evolution, The second row is the common variant zombies without secondary variation.


    The four arm mutant zombie, who acted as the leader, bore the brunt of the first wave of bullets. When the four arm mutant zombie mutated for the second time, it obtained harder skin than other mutant zombies. Its hardness can even resist the close range shooting of ordinary pistol bullets, but it still can''t resist rifle bullets.


    Not to mention the heavy machine gun, which is even more overbearing than the rifle. The secondary mutant zombie didn''t even raise a bubble, but was smashed into pieces by the concentrated bullet screen. All parts of the body were even scattered on the ground, and even a decent body was not left.


    The second batch of mutant zombies were even worse. Although their skin was hard, they couldn''t resist bullets at all. Even the smallest caliber bullets ended up in pieces like the first second mutant zombie.


    The soldiers in the defensive positions, no matter how many, each soldier has at least ten rifle magazines, and is not afraid of bullet consumption. Even if the magazines on his body are finished, there are logistics soldiers specially responsible for ammunition behind him. Each logistics soldier carries a backpack specially for receiving bullets.


    The backpack can hold at least 100 magazines, that is, the bullet configuration of an infantry squad.


    They are mobile ammunition depots on the battlefield. As long as someone finishes shooting the magazine and gives the empty magazine to the logistics soldier, the logistics soldier will give the soldier a new full magazine. After the logistics soldier is full of empty magazines, he will run to the logistics truck and get a new full backpack. There are also 100 full ammunition magazines in it.


    Such logistics trucks can basically transport hundreds of such backpacks for logistics soldiers, and each company will be equipped with two such trucks in the future, which is equivalent to that each soldier can carry an additional 20 magazines, plus the 10 magazines originally carried by himself, there will be a total of 30 full magazines, that is, nearly 1000 bullets.


    After the mutant zombies were broken into pieces by bullets, the ordinary zombies behind suffered. Even the mutant zombies were broken into pieces by heavy fire, and they are even less likely to arouse any waves.


    Countless mutant zombies were hit by bullets in various parts of the body on the way of running, resulting in the loss of various body balances. The originally aggressive zombies were directly beaten into cowards.


    Zombies running at high speed were knocked to the ground by bullets. Some were hit in the leg on the way of running, resulting in a dog biting ten, or directly breaking the neck to get up again, or directly hit the head by bullets on the way of running. Although the body is still moving forward due to inertia, it has lost control and will fall to the ground sooner or later.
