Needless to say, the bigwigs present all felt the movement of the mountains just now.

They are still in the rear at ten kilometers, and the front line is facing such a powerful explosion, and you can imagine how much pressure they are under and how many casualties will occur!

"Could it be that the heavens really want to kill millions of humans in my Tianyun base?" A big guy lamented.

More bigwigs looked a little weird in the panic. They secretly issued some orders to their forces.

The content of these orders is basically to prepare the forces for retreat.

Obviously, the bigwigs have lost hope for the future of the Tianyun Base.

Haven't you heard? There were about 600 small missiles bombarding the city walls just now! No matter how strong Tianyun's walls are, how many bombardments can they withstand? And once this kind of fort zombie is born, it will be endless!

At this time, your life is the most important. As for the supplies, they are things outside the body, and they can be taken away as much as they can. As for the millions of surviving people in the base, ask for more blessings.

Yang Chengguo felt the small movements of the bigwigs in the main government, and he also obviously noticed the frustrated look on the faces of the military generals.

He sighed inwardly.

"How often do these zombies attack? In any case, it is impossible for them to violate the law of conservation of energy. How many zombies are on the front line for them to devour and replenish? Yang Chengguo quickly discovered the key point of the matter.

'Puff'

As soon as Yang Chengguo's voice fell, a huge explosion came again. The sound of the explosion shook the command center building slightly. Dirt began to fall from the ceiling of the conference room.

The generals of the military are still calm. The big guy in the Zhengfu is two wars, and he almost wants to go first.

'Bang'

Yang Chengguo slammed the desk again and yelled, "Give me a little calm." Zombies are still far away! ”

"Report! The General Staff has already estimated. With the Fort Zombie devouring with all its might, it takes three minutes to recharge its energy and fire it again. Just now they were launched at a five-minute interval. Because there are not too many zombie bodies for them to devour in the place where the Fort zombies are located. ”

Xue Sheng: "Damn! That's the problem. If you don't block the zombies farther, there are too many zombies rushing up for fear that you won't be able to defend them. However, if you are killed in the distance, it will become a supply for the zombies of the fort. ”

"Excuse me, which team has a good way to deal with each section of the battlefield? Especially the Sky Wolf detachment, see if they have a way to deal with it? "Yang Chengguo is a dead horse and a live horse doctor.

All the bigwigs are very concerned about this issue. The same is true for Bai Xiangdong, who has always been at odds with the Sky Wolf Detachment.

"The zombies' attack this time is still the section of the city wall defended by the Sky Wolf detachment, and it has suffered the least casualties. In the first round of the zombies' energy cannon attack, about thirty energy cannonballs were fired at the A10 segment. Captain Lin Chen's detachment released the willow tree body above the central city gate and defended the section of the city wall with a total length of 70 meters on the left and right, with a total length of 140 meters. More than a dozen swifts with their abilities spat out ice spikes in the air, blasting all the energy cannonballs that hit the A10 segment in the air. The remaining few energy cannonballs are attacked by the other abilities of the Sky Wolf, and the volley intercepts and explodes. Only one energy shell landed on the city wall, destroying a point of heavy machine-gun fire. Another energy cannonball flew over the city walls, causing hundreds of casualties among ordinary people. In the second round of zombie attacks, the Sky Wolf detachment organized all the abilities on the city wall to launch a long-range interception. There were basically no casualties in the A10 section this time. ”

"Good! Quickly spread this method to all sections of the city wall. Have all the Abilities join forces to detonate the Energy Cannonball. As many as you can intercept. Tell me again, did Lin Chen come up with a new way to deal with the zombies in the fort? Yang Chengguo looked at the herald expectantly.

"The Sky Wolf detachment has come up with a solution. They reduced the range of heavy machine gun barrage and mortar short-range bombardment from 800 meters to about 300 meters. In this way, after the fort zombie fires the first shell, there is no energy supply, and it can only be dumbfired. Lin Chen then ordered all the heavy machine guns and snipers to kill the zombies of the battery. ”

"Didn't they take a harder impact on the walls than they did?" Yang Chengguo was a little puzzled.

"Division Commander, Lin Chen asked all the enhancers to put us on the city wall and let the ordinary soldiers throw all the grenade weapons thrown out. He also took out tens of thousands of grenades and hands. Grenades are thrown to their heart's content. This is equivalent to the addition of several thousand additional small mortars. There were fewer zombies on the approaching city wall than before. It's just that a few thousand capable people throw these explosive bombs, and the number is not enough for them to throw for long. They only threw some out when they couldn't take it anymore. ”

"What's more, it's the wolf that can only be relied on at the critical moment! On my command, all grenades and other throwing weapons in the treasury were to be carried up the city wall. In addition, all short-range missiles give me preset coordinates for aiming, firing a round every ten minutes. Yang Chengguo said.

Xue Sheng: "Division commander, the total number of missiles in our three divisions is only more than 500. Twenty of them will be shot in this round. We were meant to behead the Corpse King. Isn't it too early to now? ”

Yang Chengguo: "What is early?" If you don't shoot out and kill more zombies now, how many do you think we can take away these bulky missile vehicles when we finally retreat? ”

When the bigwigs heard Yang Chengguo, the military's toughest main battle faction, say the words of retreat, they all thought that the general trend of retreat was irreversible.

But since there are still ways to deal with it at the front and they are still insisting, there is no reason for them to leave the command center.

Not to the point where the mountains and rivers are exhausted, they are not willing to leave the Tianyun Base, a place where they can settle down.

......

On the missile position in Area A of the base, the missiles on top of the 20 missile vehicles have been erected high.

“...... 3, 2, 1 launch! ”

Twenty short-range missiles soared into the sky with long tail flames.

Thirty seconds later, the missiles flew over a distance of more than a dozen kilometers and slammed into the densest mass of corpses, sending out a human roar.

The effective killing range of short-range missiles against humans is three to five hundred meters. Against powerful zombies, the effective killing range is reduced to about 100 meters. The effective killing area is about 10,000 square meters.

Each missile completely killed at least 3,000 zombies, and incapacitated four or five thousand zombies with severed limbs and legs.

Twenty huge cavities appeared in the massive corpse mass.

The tide of zombies is stagnant.

As the missile landed and exploded, Lin Chen's eyes shrank.

Lin Chen briefly assessed the explosive power of the missile. He came to a conclusion: within 10 meters of the center of the missile explosion, even he was in danger of being killed in an instant. And the Sky Wolf team members are also unfortunate in the range of fifty or sixty meters!

Therefore, Lin Chen is unwilling to confront the military, and the huge power of missiles is a very important factor. In the face of missile attacks, he can teleport away, but his team members are difficult to say.

If in the face of missile saturation bombing, then ......

......

The minutes ticked by.

The defending warriors of the Tianyun base are suffering with difficulty.

The zombie attacks never stopped. On the human side, however, the casualties are getting bigger and bigger, and the ammunition supplies are getting less and less.

By 11 a.m., seven or eight rounds of missiles had been fired, and only three of the walls of fire had yet to be opened. Collapse warnings have been issued in all sections of the city wall, except for the A10 section to the north.

Lin Chen's heart gradually sank.

Could it be that he was reborn in this life, and the fate of Tianyun Base was even worse than in his previous life?

In the previous life, although the Tianyun Base suffered heavy casualties in the war against the zombies, it managed to hold on.

At this moment, some small black dots appeared in the sky south of the base.

Lin Chen looked at it, and his body shook suddenly.

"Major Yan, quickly inform the top management of the base, there is a flock of mutant birds in the south. Please land all helicopters at the base immediately. ”

......

Command center.

All the bigwigs were silent. They waited for the situation to develop to a critical point, for Yang Chengguo to admit the failure of the resistance, and for Secretary Wan to issue an order to retreat.

Secretly, the road leading to the South Gate in Area A has been placed under martial law. Many of the most critical supplies have already been loaded into trucks.

The men under the bosses who did not participate in the battle are ready to retreat.

"Report! Captain Lin Chen of the Sky Wolf Detachment sent a report. He said there were flocks of mutant birds in the south......"

"Report! The radar observatory observed a ...... in the sky about 20 kilometers to the south."

Both reports were reported to the command center almost simultaneously.

"What's the deal, Lin Chen's eyes are even comparable to mechanical radar! On my command, all helicopters landed at once. The commanding heights maintain the tracking and observation of the mutant bird flock. Yang Chengguo began to order.

"Hey, at such a critical juncture, the mutant bird actually came to join in the fun. This is the base of the heavenly death also! Someone in the Zhengfu let out a pessimistic sigh.

"Report! The follow-up news of the Sky Wolf detachment came. According to Lin Chen's detachment leader, the mutant bird flock came out of the mountain to grab evolutionary energy. Almost all of the zombies on the battlefield now have more energy than humans. The mutant bird bears the brunt of the attack by choosing zombies. Captain Lin warns us not to actively attack the mutant birds, so that the mutant birds will turn their attack direction towards humans. ”

"Really? How did Lin Chen know so clearly about the mutant bird? Yes, there are so many mutant swifts in his detachment, and they must know more about the habits of mutant birds. Then go ahead as he says. Yang Chengguo said.

"So, these mutant birds are here to help us?"

"It's hard to say. Haven't you heard that the mutant birds are there to grab evolutionary energy? Where are they here to help humanity? ”

"Whatever. At this time, as long as you can fight zombies, you are a good bird. ”

The bigwigs finally heard a good news and began to talk about it.

......

The center of the wall to the west of the site is section B10. The main forces defending the B10 segment are the Pinnacle Detachment and the Quartet Sento.

Bai Zhengfeng, who had not appeared in front of people for a long time, appeared above the city gate and had been directing the battle on the spot.

The original number of corpses from the west was about 3.5 million. After several days of shelling from the base, when the corpses attacked, there were only about 2.4 million.

Bai Xiangdong believed that with the heavy artillery in the city constantly bombarding, and the city walls were supported by mountains of arms, these zombies could not pose a threat to the base. So he took out almost all of his strength to earn this feat.

Although the Quartet suffered heavy losses in the rescue battle, the emaciated camel was bigger than the horse. The Bai family took out resources to recruit some idle ability people again, and took out the zero-level crystal nucleus to cultivate some reserve ability. Now the strength of the Quartet has recovered a lot.

The Bai family has spent a lot of resources because of this.

At the beginning, there were quite a few military and political bigwigs at the base who held the same view as Bai Xiangdong. At the beginning of the defensive war, there was not much panic in the hearts of the military and political bosses.

I didn't expect the zombies to be so weird!
