"All notices! In addition to scientific research teams, medical personnel treating the wounded, communications teams and industrial team personnel. All the rest of the team should go to the gun room to get their guns, bring the MONOCULUS system equipment, and follow the instructions of the communication personnel to enter the city wall to defend against the zombies. ”

"All notices! In addition to scientific research teams, medical personnel treating the wounded, communications teams and industrial team personnel. All the rest of the team should go to the gun room to get their guns, bring the MONOCULUS system equipment, and follow the instructions of the communication personnel to enter the city wall to defend against the zombies. The communicator's words sounded throughout the base through a loudspeaker.

"Boss, what are you?" Xue Peng looked at Liu Long in some surprise.

"Is there a better way for you in this situation? Just keep them inside the wall and you'll be on top of the wall with all the fighting members. Liu Long ordered at Xue Peng,

After the order was issued, all the female members in the base were obviously stunned for a moment, because Liu Long had always disagreed with female members participating in the battle. But after being stunned, everyone went to collect the guns without a trace of hesitation and entered the passage within the city walls. All the fighting members who were originally blocking within the city wall were all called to the wall by Xue Peng.

"Twitter!!" With a roar from the mother, a wave of corpses began to pour into the base from all directions, and the members who climbed the wall began to quickly start to block. In the dark night, looking at the zombie hordes outside the wall and attacking the city wall, the scene of ten thousand corpses attacking is enough to make people despair. The zombie army still used the same routine, rushing to the corner of the wall one by one with all kinds of pile-up debris. Flashes of fire flashed everywhere on the walls, and the smoke of grenade fire was everywhere on the walls.

Liu Long also noticed the dangerous situation of the base, and the addition of female members can only be said to be a drop in the bucket for the defense of the entire base. The zombie mother has also become very intelligent, and the distance between the besieging zombie armies is more than one meter, so the power of the grenade has been greatly weakened.

"With incendiary bombs! Dissolve the pile of debris piled up by zombies with incendiary bombs! Liu Long thought about it for a while, and then gave the order to use incendiary bombs, if it was not used, the base might not even be able to survive tonight. Xue Peng also knew the seriousness of the situation, and without a trace of hesitation, he commanded the intelligent robot unit to put down the 81 rifle in his hand and go to the gun room to take out the RS-007 rifle and incendiary grenades.

The 'Boom' incendiary bomb soon began to fire, and as soon as it hit the debris pile built by the zombie pile, it exploded and burned. All kinds of debris could not withstand such high temperatures, and they all began to melt one after another, and the fire instantly began to spread under the corner of the wall in the northwest direction, burning up anything that could be burned, and at the same time blocking the pace of the zombie attack.

"Xue Peng, come like this, as long as the debris pile built by the zombie is more than ten meters high, you will use incendiary bombs to dissolve him for me." Liu Long saw that the power of the incendiary bomb on the pile of debris was very huge, so he commanded Xue Peng.

----------------------

Time flies, and the battle between the zombie army and the base continues for four days. Due to the illegal construction used to hinder zombies every day, more than half of the incendiary bombs produced in the base are consumed every day. The zombie mother is very smart, except for the attack on Liu Long and the time when the troops went out, they didn't appear again, and the long-range troops of the zombie forbidden army have a flaw that there is no cover on the top of their heads when they hold stones in both hands, unlike ordinary zombies who are holding all kinds of heavy objects to attack the city.

For four days, the sniper members on the city wall, both men and women, took turns resting and fighting each other, and finally managed to survive until the incendiary bombs stored in the base were enough to carry out a war of extermination. In the space of a week, Li Jianliang blocked five zombie groups with more than 50,000 numbers, so that Liu Long increased the multi-functional artillery shell production line at the base to twenty. It also purchased 20 production lines of RS series guns, each costing 100,000 gold coins, which can produce 1,000 rounds of ammunition of various RS series per day.

"Get out of town!" With Liu Long's nod, Xue Peng controlled the robot troops out of the city.

The RS series guns are all miniature ammunition used, and the ammunition caliber is pitiful, from 1.1 mm to 0.7 mm of various calibers, simply like a needle. Since the RS series guns are all mixed kinetic energy shooting such as air and electromagnetism, the bullets are only materials with high hardness, and they do not need to be filled with gunpowder and so on. Moreover, the initial velocity of the bullet is extremely high, which can fully ensure the accuracy of the small-caliber bullet after firing. Each gun is electrically supercharged, and it can continuously fire millions of rounds of ammunition after being charged, so there is no need to worry about the energy part. That's why this gun is so big and so heavy.

The robot troops advanced very quickly, and after receiving orders, they quickly left the city, and the muzzles of their guns sprayed bullets rapidly. The firing rate of 2,000 rounds per minute, and the penetration of 800 meters through 50 centimeters of ordinary steel plates, make the robot unit invincible. No matter how heavy the debris the zombie holds, it is like paper paste for the sixth-level black technology RX-007 rifle.

Lift the gun, pull the trigger, put it down, lift the gun again, pull the trigger again, the robots have been doing a very standard and a hint of disobedience, every time the gun is raised, more than three zombies will be penetrated to death. The robots advanced alternately under cover, and the cold and ruthless robot army soon passed through the impact zone of the zombies and came to the front of the zombie army. The robot that first came to the zombie army was a shuttle bullet at the zombie army, and after it was empty, it instantly switched to grenade mode and fired at the zombie army.

After the mother discovered this special team, she began to send a large number of zombies to attack this team. However, it was useless, the zombies dispatched were quickly shredded by the ordinary ammunition of the guns, and they could not get close to this group of tall robots until this group of robots rushed to the front of the battle. A sense of crisis swept through the whole body of the zombie mother, and a pair of small eyes showed a look of fear, not caring about the zombie army at all, and running away with some of the zombies near him.

The Molotov cocktail quickly ignited the position of the zombie army, and the zombies insisted on carrying out the orders of the mother, unaware that their boss had begun to flee. Like moths to a fire, the zombie hordes rushed from all directions towards the robot troops that fired incendiary bombs. And the robot troops were very calm, firing incendiary bombs at the zombie group rushing behind them.

The flames released by the incendiary bombs instantly engulfed everything, and from the top of the wall, it looked as if the robot troops had been engulfed in flames. Seeing this scene, Liu Long's heart began to panic.

(Don't panic, these robots are made of the same material as the Stellar Ore Gathering Ship.) ）

(Collecting stars?) What kind of star is the sun? ）

(Yes the host!) ）

Listening to the system's words, the corners of Liu Long's eyes jumped. I can't help but think that if there is no doomsday crisis, I would be a super-rich man just by selling these materials.
