There are more than 200 birdmen flying from the northwest, and there are as many as nine of them that have reached the fourth-level standard. And among these nine-headed birdmen, there is one that is very different, and the strength of the source power shield on his body is almost the same as that of a terrestrial type awakened person. This unique feeling of standing out from the crowd immediately attracted Lin Feng's attention.

After receiving Lin Feng's alarm, the entire 77th Brigade was arranged according to the air defense formation. It's really unwise to fight a birdman in the wild without adequate protection, especially if there are a large number of Awoken people peeping nearby on the ground.

The heavy artillery of the task force opened fire again, and this shelling was purely to drive away the awakened nine kilometers away, so that the troops would not be subjected to a ground assault while dealing with the attack of the birdmen in the sky. Under the blow of 152-mm artillery, more than a dozen groups of awakened people who had been hanging around the 77th Brigade retreated one or two kilometers in place after being shelled.

While the heavy artillery group was still firing suppressively, other units other than the artillery had already begun to prepare for the next air defense operation. Now in the wilderness, surrounded by no shelter, although there are enough anti-aircraft artillery, after all, the geographical advantage is very disadvantageous. There are more than 200 birdmen, and if they also play high-altitude bombing like last night, it will be a very headache.

The 77th Brigade was formed from one regiment from each of the three main divisions, of which the 120th Division sent a tank regiment, the 88th Division provided an anti-aircraft artillery regiment, and the 135th Division sent a heavy artillery regiment, in addition to three Evolver battalions mixed and a small number of semi-awakened Men Task Force reinforced brigade. In addition, in order to deal with the increasing number of Level 4 Awakened and Birdmen, the Anti-aircraft Artillery Regiment has equipped an additional forty 100mm high-level dual-purpose anti-aircraft guns—all of the gunners who operate the guns are shooting evolutionaries.

While the heavy artillery regiment's large-caliber artillery frantically engaged in expelling fire, the other units took advantage of this short time to frantically prepare for the upcoming birdman air attack.

Based on the lessons learned from the battle with the Birdmen in the early hours of this morning, Lin Feng temporarily wrote a summary of the experience of fighting against birds, and after discussing and revising it with several evolutionaries in the army, it became a new version of the dogma of fighting against the Birdmen. In the morning, when the troops were integrated, this combat doctrine was distributed to everyone in the brigade.

On the day of the battle, a few hours later, the post-war experience summary was spread throughout the army, and such an efficient speed of 'experience' sharing was completely forced out by the awakened. In the old days, this was simply unimaginable. In the face of the awakening day by day, human beings can only keep up with their progress by speeding up their "strain rhythm".

As soon as Lin Feng called the police, all the officers and men of the 77th Brigade immediately began to prepare in accordance with the operational doctrine. All vehicles dispersed at certain distances in anti-aircraft formations. The towed anti-aircraft guns were quickly deployed and put into a state ready for launch, and the 37-mm self-propelled anti-aircraft combat vehicles calibrated by the radar were also ready for combat in a short time.

In addition to these military equipment, ordinary evolutionaries are also not idle. An Evolver with the Microwave Heating skill melts the snow around them, and an Evolver with the Water Control Skill. manipulated the melted water by them, condensing into a huge ball of water around them. Standing next to the water-controlling evolutionary are the telekinetic evolutionary and the frozen evolutionary. When fighting the Birdmen for a while, they are an important combat force.

And the power-type evolutionaries in the army are almost a 12.7 mm heavy gun in each hand, and they form a square formation with a group of four people ten meters apart - after the outbreak of the Awakened crisis, the design of special weapons for the evolutionaries has long been placed on the proposals of each **. In order to gain time, the 12.7 mm heavy machine gun, which was previously equipped on tanks, was directly mass-produced with only minor improvements, and was standard equipment in the hands of power evolutionaries. Its production priority is second only to large-caliber anti-tank guns.

As for the evolutionaries of other skills, they also have their own division of labor, but all energy skill evolutionaries have strict restrictions on the use of skills.

Large legions are not fought in small groups of a few people, and you must be very careful when using energy-based skills, because all energy-type evolutionaries have an attack range of 100 meters. When a large army is intensively engaged in warfare, it is very easy to misuse skills in a chaotic manner - this is not a joke, but a fact. In the past few days of the Great Lawn Mowing Operation, the 'murderer' who has suffered the greatest losses from the human army is the fourth-level awakened person in the first place, and the second place is the 'accidental attack' of the energy skill type evolutionary on the side. The third is the turn of the third-level awakened - this situation is a 'common phenomenon' in the whole world, so much so that there is a similar bad joke circulating in each ** team: the energy skill type evolutionary on this side is more dangerous than the third-level awakened.

From Lin Feng sensed that the birdman approaching twenty kilometers away and sounded the alarm, only a little more than three minutes later, the army of more than 200 birdmen appeared in the air northwest of the 77th Brigade at three heights: high, medium and low.

A nine-headed fourth-level birdman located at an altitude of more than 4,000 meters. The artillery radar on the air defense combat vehicle could not lock them, but the second- and third-level birdmen located in the middle and low layers, they were clearly displayed on the radar screen - in fact, as soon as the birdmen were dispatched, the radar also detected them early, and the role of the perceiver was mainly to detect the most dangerous fourth-level birdmen.

The awakened on the ground have become "wiser", and the birdmen in the sky have also learned to behave. At first the radar spotted them. These birds are arranged in a formation of twelve 'humans'. However, when they approached the 77th Brigade more than a dozen kilometers away, they took the initiative to abandon the flight formation, which was almost a live target, and then dispersed far away, and more than 200 birdmen scattered into a large net and headed towards the 77th Brigade.

Forty 100-mm anti-aircraft guns were the first to open fire, and under the control of radar and firing commanders, they opened heavy fire on the birdmen at a distance of 12,000 meters. However, due to the early dispersion of the awakened, the effect of the artillery bombardment was like a cannon hitting a fly, and it was too good, forty guns fired nearly 600 shells in one minute, but only more than 50 birdmen were shot down and wounded - only 12 birdmen were actually shot down, and the rest were scratched by flying shrapnel. However, the birdmen below level 4 are all glass people, and the slightest injury will affect their ability to fly, and these injured people all quit the battle.

Eighty seconds later, the birdmen flew into the sky above the 77th Brigade, and the remaining nearly two hundred birdmen cast their skills in the sky like hens laying eggs, and countless fireballs, freezing gas, and ball lightning fell from the sky. Correspondingly, there was a frantic firing of all kinds of anti-aircraft fire on the ground.

The cannon roared on the ground, and the lightning and fire in the sky appeared at the same time.

The masterpiece of human mechanical civilization collides with the highly evolved abilities of the Awakened ** in the most intense way here!

At a low altitude of 2000, the second-level birdmen were under the guidance of the artillery aiming radar and the precision strike of the shooting evolutionary, and they were like cannon fodder at low altitude, and they were killed by the ferocious anti-aircraft fire on the ground after only one or two skill attacks. In just ten seconds, almost all of them were slaughtered.

But the smile of the 'mechanical civilization' manipulator lasted less than twenty seconds, and twenty seconds later, the blow from the air arrived. Hundreds of fireballs, freezing air, and ball lightning. Like hail, it fell on the head of the 77th Brigade. The strikes of the Awakened were extremely targeted, and all the attacks were almost exclusively directed at the air defense forces.

The Fireball Technique of the Birdman is just a small incendiary bomb, the fireball technique of the second-level Birdman has a killing radius of between three and five meters, and the third-level Birdman is about ten meters, and the fireball technique has limited damage to closed armored vehicles such as tanks, but it is extremely harmful to bare targets located on the ground. And there aren't many ways to respond effectively to this kind of attack.

More than a hundred fireball bombs fell one after another, and the telekinesis-type evolutionaries in the three evolutionary battalions were in full array. Some telekinesis masters use telekinesis to compress the huge fireball, reduce the range of its impact, and then move it to an open space when the fireball is about to end. This technique is the most effective way to deal with fireballs summed up by the confrontation between evolutionaries and birdmen in various countries around the world these days - the only problem is that this method requires a high level of skill manipulation skills of telekinesis, and there are not many evolutionaries who can do it perfectly.

And most telepathic people simply use telekinesis to "wrap" the target they are protecting, forming an invisible "telekinetic shield". When the fireball is stopped by the telekinesis shield when it falls, and when it is temporarily blocked, the telekinesis then uses the telekinesis to wrap the burning fireball and push it aside. The original creator of this "stupid method" is Lin Feng, and the skills are very simple to master, and he has proved to be extremely effective after being 'developed' by actual combat. So it was quickly promoted among telekinesis, but the biggest disadvantage of this trick is that the loss of mental power is greater than the former.

Part of the fireball falling from the sky was intercepted by the telekinesis and landed in the air, and the other part was directly crooked, but there were also a small number of soldiers or vehicles that were hit, and the work of extinguishing and rescuing the fire was all done by the evolutionaries of the frozen system, especially the preparation was sufficient, and the damage caused was extremely small.

Although the fireball of the white-feathered birdman is menacing, it is the best one of the three birdmen. The more troublesome thing is the freezing breath of the black-feathered birdman. The freezing air emitted by the third-level black-feathered birdman was as low as minus 200 degrees, once it was hit by him. Even a Level 2 Evolver would have been killed on the spot - fortunately, due to the birdmen's high-altitude bombardment, the high-density frozen gas they released at a height of 3,000 meters had already spread over a long distance, and the lethality was almost non-lethal when it reached the ground. It was only a cold wind of minus 40 degrees Celsius.

But when the anti-aircraft artillery position was hit by this freezing air, the temperature dropped sharply, and the evolutionary could still endure this temperature, but the ordinary soldiers were so cold that they were almost frozen.

Compared to the fireball technique of the white-feathered birdman, the freezing air of the black-feathered birdman and the ball lightning of the yellow-feathered birdman are almost impossible to defend against. The ball lightning emitted by the Yellow Feather Birdman is the same as the ball lightning produced by the thunderstorm in nature. It's a ball of lightning in the shape of a ball.

The third-level yellow-feathered birdman was a ball lightning bolt emitted at a height of three thousand meters, and it was extremely fast, falling to the ground in a few seconds. What's even worse is the nature of electricity, when they fall to the ground, they automatically lead directly to metal or magnetic objects, almost none of them miss, and the damage caused is also strange.

The two tanks were struck by ball lightning, and the balls of electricity, no more than the size of a football ball, penetrated the armor on the outer walls of the tanks and entered the hull, destroying all the electronics on board before exiting the vehicle. As a result, the armor of the outer part of the car was melted, but the metal part of the inner wall was intact, and the two occupants suffered minor burns.

Three self-propelled 37-mm anti-aircraft guns were also struck by ball lightning, and similarly, all electronic equipment on board was destroyed, killing two occupants on the spot, and several others were injured to varying degrees.

But the most terrible thing happened in the open gun emplacements, where the steel cannons were good conductors of electricity, and attracted the ball lightning bolts that had been shot down like honey to bees. Four guns were 'hit' by this ball lightning. The ball lightning 'rolled' along the barrel of the cannon facing the sky, and then directly 'smashed' the gunner who operated the artillery, causing the terrible 'spontaneous combustion of the human body'. The three gunners struck by ball lightning burst into flames like torches, turning to ashes in a matter of seconds. Although the gunner of the fourth anti-aircraft gun was lucky not to be hit and escaped the fate of 'spontaneous combustion', the ball lightning detonated the shells mounted on the gun mount, and the shrapnel and storm from the detonation of the ammunition swept all life within a radius of several tens of meters around the gun position.

There were only ten yellow-feathered birdmen in the sky, but the ball lightning they sent out caused more damage and destruction than all the second or third birdmen combined. Of the ten ball-shaped lightning bolts that fell from the sky, only one was resisted by Lin Feng.

At that time, Lin Feng personally guarded Zhao Qingfeng and Zhu Ming's gun position, and he used his newly created electromagnetic manipulation skills to create an "electromagnetic cover" with a diameter of ten meters around his body, and when the ball lightning fell, it collided with the electromagnetic cover and was directly disintegrated in the air.

The shielding electromagnetic cover used by Lin Feng is the strong electric manipulation ability of the body itself, combined with the electromagnetic manipulation skills he harvested from Zhang Ting, and the new skill born on this basis is also the only way to effectively resist the spherical lightning attack. It's just that in this battlefield where humans are fighting against the Awakened, the scope that Lin Feng can take into account is really limited.

In less than twenty seconds of confrontation, the birdmen in the sky and the human army on the earth, each side suffered a lot of casualties. On the surface, the Birdmen have suffered more losses, but their real main killer has not yet been played.

The following word counts do not affect subscriptions

Note: Ball lightning is still a mystery even now, and humans have not been able to create real ball lightning in a laboratory to this day. Jay Tesla, the Frankenstein who has been hyped on the Internet, is said to be the only one to solve the mystery of ball lightning, but unfortunately his research has not been circulated to the world. There is a saying that the beautiful demon country hid all his research.

Because this is the mystery of unsolved science, it is difficult for frogs to talk too much about how to defend against it, how to make it, how to trigger ball lightning - because the more they talk about it, the more nonsense it is. As for using an electromagnetic shield to shield and resolve ball lightning, it should be the setting in the book, don't delve into it. If you are interested in ball lightning, you can go to Baidu Encyclopedia to take a look, which has everything about him in detail.

The ball lightning frog had seen it with his own eyes when he was working in the unit, and a rolling thunderbolt fell on the flower bed in the unit at that time, and disappeared after rolling for a few seconds, breaking a flower garden lamp.
