Chapter 451

Bang hum, strange scream in the ear explosion

In the wasteland area, the two square kilometers of land, one after another of the alien figures from the whirlpool of soil.

"Thermal imaging failure..." There are front-line personnel using thermal imaging detectors to target those flying hydras, but it doesn't work, it can't detect the heat. Either the alien has anti detection capability or the body has no infrared radiation, both of which are puzzling.

Bang, bang, bang, gunfire continues. There are shells and individual missiles.

However, with another howl, the signal is destroyed by interference, and the missile explodes when it is still advancing.

There have been hundreds of flying hydras surging out, but the fighters have not been able to hit even one of them, but no casualties have been caused for the time being, so is the mysterious Bureau. It seems that these flying hydras can not break through the space barrier and can only move in the multi boundary overlapping area.

At present, it is almost certain that in addition to the natural world and the mysterious world, there is another world in the wasteland area, which may be the wasteland world.

Although the enemy is still trapped, but Deng Ximei, Lou Xiaoning and others are almost unable to hold on. The light of the old yinnet is weaker and weaker, and the spirit of the people is more and more exhausted.

"Don't let them break through the line of defense..." Deng Ximei had a bad feeling. It was not only related to the battlefield here, but also related to a lot.

At this time, at the command center's command, the long-standing UAV formation took off and flew into the wasteland area to fight.

These are not small drones. They are all military drones. High speed shooting and bombing are enough to turn an area into ruins.

However, as soon as they crossed the boundary, there was nothing else in the air at the first moment, and then a few flying hydras appeared in the next moment. These strange tentacles entangled the UAV with a sudden burst of amazing power, directly breaking the steel artifacts in their hands.

A riot of explosions, a drone fell.

"Ready to retreat!" The unmanned communication vehicle of xuanmi Bureau has not been destroyed, but it can also send a more vague signal: "the power of purification network is insufficient, and the ritual power is about to expand. Ask the space crew to withdraw immediately within one minute. We will hold on first, and after ten minutes, the missile will strike indiscriminately. "

In the command center, Tongye and the other side of the war zone quickly agreed to this plan, which means indiscriminate attack and saturation attack.

In other words, missiles are used to dump, but the whole area is bombed. Saturation is to attack the same target in a short period of time with high density, all levels and continuous attacks, and the attack degree exceeds its anti Strike ability, making the target unable to cope with it.

The former individual missiles failed because of the whistling of flying hydras, but they should also be consumed.

as long as they are exhausted, they may be blown up

Even if it can't blow up high above the ground, we should also control the ground, and we can't let more species break through the ground like this.

"Ah..." But when Lou Xiaoning heard the order to retreat, he was really unwilling, but he was really unable to support it, and time could not be delayed.

She lifted up her hand and fell away from the stone

Mo Qing, Sammy Walter, Helen Claire and others are not willing to accept it, but at this moment, there is only one way to retreat.

The enemy is very powerful, more powerful than the burrowing giant worm, stronger than the ghoul, stronger than the deep diver.

When she left in a hurry, Deng Simei looked back and was at a loss. If she retreated again, where would she go

All the front-line materials, including the old India stone, were not needed. All the front-line personnel boarded the helicopter and the vehicle at the fastest speed, and then drove away in all directions. In the wasteland area, there are still some flying hydras breaking through the soil one after another, and the number has exceeded 300.

After a minute, Tianji personnel had been evacuated, and mysterious personnel began to evacuate.

Ten minutes later, both sides were at a distance from the dividing line.

All kinds of missiles began to be launched, such as the Tianji world and the mysterious world. They were constantly attacking this small area.

Huge roars and explosions were also heard in the command center. Some missiles failed and exploded at the boundary line, some exploded in the air, and some landed on the ground.

It is impossible for people to know whether they have killed that kind of alien life. The signals in the area and the boundary line have been cut off, and the mysterious Bureau has also lost contact. The satellite can only take distorted images that are too vague to see clearly. And according to the retreating front-line personnel, that kind of weird howl, is still far away.

In less than 15 minutes, all of a sudden, the wasteland area should have spread.

The surveillance, which was set up three kilometers away from the original wasteland area, suddenly caught the flying Hydra flying by.

In the command center, people were watching nervously. It was not clear how big the new area was. The helicopters and vehicles used by the front-line personnel just continued to retreat, while the UAV formation drove in to block the enemy and determine the scope

Are those missiles really useful?

Is the nuclear bomb already a major option for decision makers?Is there any weakness in this alien species? What are their weaknesses

In the communication room of the isolation base, Wang Ruoxiang and several other people are also watching. These thoughts are fluttering in her heart, and they are also in a daze. Because the known biology and medicine of mankind can not explain the flying Hydra. What power does it rely on? How can it be invisible?

Ghouls are understandable. That's just a variant of human beings, and so are deep divers.

But the creatures in front of them, once again, broke their minds.

At this time, there was another situation, a large number of patients in the isolation base developed new symptoms.

The monitoring video recorded in the ward was immediately received. Wang Ruoxiang, sikuoxian and other people looked at it suspiciously.

These are the second batch of patients. Some of the teachers and students in Mobei senior high school were artificially comatose due to insanity and extreme pain; some were not totally irrational and were only fixed in hospital beds for the time being.

Just now, more than 100 people suddenly trembled, and their muscles were stiff. The eyes of those who were awake turned white and their faces twisted strangely. But the symptoms didn't last long, more than 30 seconds, and they all calmed down, calmer than before.

Patients in artificial coma opened their eyes and walked out of the hospital bed because there was no binding; the fixed patients could not unlock the lock, but they also sat up.

They all looked at the surveillance cameras in the corner of the ward.

It was like a normal person asking for a conversation.

Wang Ruoxiang recognized several teachers and students, including math teacher fan Jianguo, male students Hou Xingxing and Zhang Zihao, female students li Xintong and Xu Yan

At this time, the images are in synchronous communication state. Looking at the camera, these patients suddenly say at the same time:

"Hello, human friends. We are Isis. We are from the future."
