"According to the movement speed of the corpse group at 40 kilometers per hour, it is estimated that it will come to us in 10 minutes, and our task is to stop them and hold them for at least two hours, otherwise the gathering will fall into a very passive situation." Xu Yangshao's expression was very heavy, and he could see that this task was not a lot of pressure.

"Two hours? It's not easy, but it's not impossible. Yang Shan thought lightly.

"Boss Yang has a good plan?" Xu Yangshao's eyes lit up, staring at Yang Dan and asking.

"There is no good plan, but I can contribute part of my strength." Yang Dan replied and waved his hand forward, using Ali Cangcang's 'summoning technique' service to summon all the chariots and robots.

"We can hold the thousand-meter front to form an absolute defense, and it's okay to leave the rest of the front to you, right?" After summoning the chariot and robot, Yang Shan asked.

"If Boss Yang can really defend the thousand-meter front, our pressure will be much easier, and it should be no problem to complete the task." Xu Yangshao nodded, slightly relieved, and his eyebrows soothed a little.

"That's good, you can go to a kilometer away and prepare for defense, I guarantee that my area is the last to be breached, no matter how many zombies come, I will definitely complete the two-hour mission!" Yang Dan's expression became serious and solemn, and he solemnly made a promise.

"Then please!" Xu Yang didn't talk nonsense, and after a military salute, he took people away and went to fight in other vacant positions.

The adventurers in the vicinity also dispersed, and their movements were very fast and neat, without the slightest drag or mud.

They all chose to believe in Yang Dan and believed that he had the strength to fulfill Chengruo, after all, he was a person who broke out of Yuanhe City, and he knew that he had powerful hole cards with his ass, so the adventurers consciously scattered thousands of meters away, so as not to get in the way of themselves and drag them back.

Yang Shan ignored the soldiers and adventurers, and immediately commanded the chariots and robots to line up in formation, ready to meet the corpse herd.

The 10 combat vehicles are 100 meters apart from each other side by side, 140 Level 3 combat robots are side by side with the combat vehicles, and 500 domestic robots are located behind the combat vehicles, thus forming a large-scale defensive position.

The vehicle is in maximum readiness mode, and all laser guns and laser cannons are mobilized; The battle robot transforms into a laser gun Gatling with both hands, and a laser cannon is cut out of its chest, and all the fire is aimed directly ahead.

Armed with a laser sword, the housekeeping robot is tasked with killing any fish that slip through the net.

After all, the number of corpses is huge, and no matter how powerful the chariots and combat robots are, it is inevitable that there will be fish that will slip through the net, and it is normal for a small number of zombies to rush through their defenses.

To deal with these fish that slipped through the net, a housekeeping robot with a level 3 laser sword is enough.

Because after the firepower strafing of chariots and combat robots, even if there are zombies rushing through their defense lines, they must have suffered a lot of injuries, so the housekeeping robots belong to the harvesting position, even if they are weak, it doesn't hurt, what strength do you need to harvest residual blood? A good 'pig killing knife' is enough.

"Little girl, what is the limit of the current natural laws of the Heavenly Dao?" After arranging the troops, Yang looked at the stupid girl and asked.

"As long as it doesn't exceed the fifth-level cultivation, the fourth-level peak cultivation can go all out, and I don't have to shrink back to suppress the cultivation." The silly girl replied cutely, without the slightest sense of crisis.

"Very well, take me into the sky, fly over the chariot." Yang Shan nodded and said.

The stupid girl didn't say anything, but obediently grabbed his arm and jumped up and flew up, taking him to the air.

The 10 Level 4 Combat Robots flew up with them, always guarding them.

Lin Dahai and other 34 students were not slow, and they all equipped their mecha and flew into the sky to meet the arrival of the corpses.

After more than a month of self-training, they have reached the level of a driver at the beginning of the fourth level, and Lin Dahai is the most prominent, and his strength has reached the height of the middle of the fourth level.

Wait like this for ten minutes.

"Roar...... Roar ......"

The corpses did not disappoint everyone, they arrived as promised.

"Damn, it's so scary." Witnessing the ever-changing scene in front of him, Yang Dan felt a little numb in his scalp.

With the blessing of the Origin Heart Fire, coupled with his foresight, Yang Dan could see things two thousand meters away, but he felt that those things were a little small.

I saw that the dense zombies were pouring towards the Longmen Great Plains like a flood, and there was no grass growing where they passed, and all the grass and trees were eroded and melted by the poisonous gas on their bodies, leaving only patches of poisonous mist and scorched earth.

The rolling poisonous gas enveloped the waves, and the whole looked like a purple-black flood hitting a mountain col, and the horror could not be expressed in words.

Take a closer look at the zombies in the corpse group.

The zombies running on the ground have all become orc-like appearances, no longer the walking dead in their human form, and the poisonous gas covering them is more powerful than before.

Among the orc zombies, there are cat-headed zombies with good speed, tiger-headed zombies with superior strength, and huge elephant-headed zombies, etc., anyway, they are the same as the legendary orc form, but they add the essence of zombies, and the body is slightly decayed.

It's a combination of zombies and orcs, and it's fitting to call them orc zombies.

However, those fourth-level zombies flying in the air were not orc forms, they were not much different from living humans, but their skin was a little paler, and there was a strong poisonous gas that could not be concealed.

"Alert: Crisis is within two hundred meters of the tank, fire!"

The 10 vehicles gave the command to fire at the same time, and they used the external loudspeaker function, so that their sirens could be heard by anyone within a radius of two or three kilometers.

"Dada...... Rumble......"

After receiving the order and instructions of the chariot brain, all the external laser guns and laser guns fired at the same time, forming a dense rain of bullets, and staged a French 'hot kiss' with the charging corpses.

This 'kiss' can be described as vigorous, and the explosion sound formed is terrifying, and batches of zombies are beaten into a sieve and fall to the ground weakly, and more are bombarded to pieces, and some unlucky fourth-level zombies will also be bombarded into slag in front of them.

But the number of corpses is an advantage after all, although the chariots and robots suppress the firepower, but they continue to go forward and follow, even if the chariots and robots are 10 times more fierce, they can't stop the pace of the corpse herd.

However, the chariot and the robot have broken the momentum of the corpse herd forward, although they cannot stop a hundred meters away, but this distance of more than 100 meters, they need to use the lives of countless accomplices to pave, so they do not think of rushing in front of the chariot in half an hour.
