'Da-da-da-da. In addition to the troops outside the city, the entire northwestern wall was also heavily gunfired. The zombies sent a large number to harass, so that the artillery fire on the northwest wall could no longer support the troops outside the base.

"Boss, I found that the zombie group is detouring to the northeast of the base, and there are quite a few of them." The communicator's voice sounded in Liu Long's ears, and Liu Long frowned and looked at the group of zombies in front of him who were not afraid of death.

(The system, the intelligence of the zombie mother, has really reached this point?) ）

(Master, it is certain that the intelligence of the zombie mother is indeed very high, if it weren't for the low intelligence of ordinary zombies, they can only understand the simple orders of the mother zombie, and the human race would have been extinct long ago.) ）

"Boss, the zombie army has begun to attack in a roundabout way!" Xue Peng's anxious voice sounded in Liu Long's ears.

"I see, I've been notified. Let's prepare to send intelligent robots, this time we must eat a part of the zombies to reduce the threat of zombies to us. Liu Long said to Xue Peng through the magic eye system.

While sending 100,000 zombies to fight against Liu Long's troops, the zombie mother began to command an army of more than 300,000 zombies to return to the direction of the base gate, preparing to encircle Liu Long's team. The mother zombie knew that if it had been surrounded in a roundabout way from the beginning, it would definitely be discovered. So he was smart enough to first send 100,000 zombies as a barb for fishing, and then the 300,000 zombie army began to carry out a roundabout encirclement operation.

"Two hundred meters, artillery advance!" With Li Jianlin's order, the three rows of soldiers facing the zombie army neatly stopped shooting, took out the grenade from the ammunition box next to him, put it into the launcher, pulled the trigger, picked up another one, put it into the launcher, and pulled the trigger.

It turned out that after the first two rows withdrew from the formation just now, the spacing between the soldiers remained the same, and the members of the last two rows who withdrew from the queue quickly carried boxes of steel ball grenades from the back and placed them next to the three rows of soldiers for easy access.

The 'dong dong dong' artillery fire soon began, and the zombies in the shelling area 200 meters away were instantly emptied, and small craters appeared on the ground after the explosion. The subsequent zombie hordes quickly filled the cleared area again, and then was cleared by artillery fire again. The grenade was like a plow, firing at the zombie horde rushing in front of it over and over again. In order to implement her encirclement plan, the zombie mother began to order the zombie group to attack the troops in formation, regardless of casualties, and all the firepower brought out by Liu Long was contained by the zombie troops as a fishhook, and there was no manpower to resist the roundabout zombie army.

"Roar!" Soon a dense group of zombies appeared in the northeast direction of the team, and the roundabout zombies had already begun to implement the encirclement of Liu Long's troops, and from a distance, you could see groups of figures in the dark, as well as those pairs of flashing red eyes. As soon as the roundabout zombies appeared in the northeast of the base, the gate of the base was slowly opened, and intelligent robots trotted out of the base with RS-007 rifles, and the robots and Liu Long's troops quickly converged.

The roundabout zombie army formed a fan around the direction of the base gate, and then began to charge, rushing towards the base gate like a torrent. The intelligent robot also formed a fan-shaped blocking formation unhurriedly, raised the RS-007 rifles in their hands one by one, aimed at the zombie army coming from the northwest direction, and pulled the trigger.

'Bang Bang Bang' fired a few incendiary bombs from the gun quickly, and after a morning, the base produced 8,000 ultra-concentrated incendiary bombs. The incendiary bombs fully covered the onrushing zombie army. From the moment the first incendiary bomb landed, the flames rose into the sky, and then quickly extended the enveloping range backwards with the falling incendiary bomb, and the zombies without any protection were instantly vaporized before they could react. The intelligent robot unit kept firing incendiary bombs in front of them, and with the range covered by the incendiary bombs, they slowly moved towards the place where the zombies attacked at a uniform speed, constantly extending the attack range of the incendiary bombs.

"Twitter!!" It was too late for the zombie mother to be found, and the 300,000 zombie army was completely enveloped by the range of the RS-007 rifle. Losing such a large number of zombies in an instant, the zombie mother body was completely angry, he had never encountered such a difficult human being, although he had been very careful, what he got was failure again and again, and each time it became more and more serious. The zombie mother completely gave up any plan, and the mother ordered the remaining zombie group to attack, and the zombies had to use the crowd tactics they were best at.

In an instant, the surrounding zombie army was boiling, as if the floodgates had been opened, and all the zombies quickly rushed towards Liu Long's troops and the northwest wall of the base. Liu Long's troops began to encounter obstacles, as a zombie turtle shell formation appeared in the grenade-covered area. Although not all zombies carry heavy objects or shields, but a large number of ordinary zombie groups are mixed with zombies from these special operations. But because of this, it caused a lot of trouble for the blockade. (The hundreds of thousands of light infantry are mixed with some heavy infantry, and the former is definitely more of a headache than the team that is purely light infantry.) ）

The sudden attack of the zombie army has a very huge impact on the entire battle situation, although the specific location of the turtle shell array can be detected with the help of the magic eye system, but it still has a great impact on the artillery strike, and the mixed army of zombies is advancing little by little, and the speed of advance is accelerating little by little. All members of the blocking queue also increased the frequency of the cannonballs, and the zombies were completely speeded.

The entire northwest direction was full of zombies rushing out, and even on this side of the city wall, there were many zombies rushing out. The city wall of the base could no longer give Liu Long's troops even the slightest help, because there were too many zombies, and the zombies on the northwest wall could not be stopped at all. Liu Long and the others didn't calculate that the belly of the zombie mother body was so small, and they just might have to eat some of his zombies, which attracted his Jedi counterattack.

The zombies outside the city walls carried all kinds of things like worker ants, and soon broke through the bullet rain forest on the city walls. Since Liu Long brought out a lot of team members, the number of fighters on the city wall was really limited, and there were only sparse grenade attacks on the top of the wall. Compared with the 800-meter-long wall defense, more than 1,000 people are really not enough. The number of zombies is really difficult to contain, and there are constantly zombies carrying items to rush under the walls of the base, and all kinds of items begin to be quickly piled up under the city walls by zombies.

And Liu Long's side was also miserable in the face of the zombie tide, and the defense line was being pushed closer little by little. The incendiary bombs killed a large number of zombies on the two defensive surfaces in the northeast and due east, but soon the incendiary bombs of the intelligent robots were emptied, and they could not support the northwest defensive surface of Liu Long's formation at all.
