The number of yellow-feathered birdmen was only ten, and in the first twenty seconds of heavy shelling, two yellow-feathered birdmen were shot down.

"Brigade Commander, tell the Perceiver to guide the shooter and kill the Yellow Feather Birdman!"

After realizing the threat of the Yellow Feather Birdmen, Lin Feng immediately regarded them as an important target. Soon, under the guidance of the perceiver, the vast majority of the 37-mm anti-aircraft guns of the anti-aircraft artillery battalion were pointed at the yellow-feathered lightning manipulator.

Although the ball lightning of the Yellow Feather Birdman below level 4 is quite powerful, the disadvantage is that it requires a long skill cooldown time and preparation time. When they were considered a priority target by the air defense forces, they had only time to fire one more ball lightning before they were shot down or wounded by intensive anti-aircraft fire and fled.

Before being expelled from the battlefield, they sent out four ball lightning bolts, killing and wounding several more soldiers, and scrapping the electronics on both armored vehicles. Fortunately, the Yellow Feather Birdman is the least abundant of birdmen. Unfortunately, among the nine fourth-level birdmen hovering in the sky, the one with the strongest protection of the source force shield also happened to be a thunder birdman. Lin Feng felt that his current flight altitude was about six thousand meters, more than a thousand meters higher than the other fourth-level birdmen.

"Could it be that he is a fifth-level birdman?"

This judgment made Lin Feng very shocked. Relying on the puppet technique, Lin Feng was confident that he could defeat any fourth-level awakened person, but after seeing the fighting method of the fifth-level thunder-hand and seeing the form change, he knew that he was a tough opponent, and he was not the opponent of a fifth-level awakened person no matter what.

In just one minute, in the air-ground confrontation, more than 200 birdmen were quickly slaughtered by the ferocious anti-aircraft fire on the ground, and only more than 40 remained. The nine-headed final birdman, who had been hovering at a high altitude to make soy sauce awards, only then descended to a height of 3,000 meters like waking up from a big dream and joined the air attack.

And the 77th Brigade on the ground, after clearing most of the birdmen, also moved out of the last trump card at this time.

The Hongqi-20 shoulder-mounted man-to-air missile, which was urgently developed after encountering the fourth-level awakened crisis, uses the latest television guidance method and uses a special shaped energy armor-piercing warhead -- however, today, when production has been disrupted, due to the strict restrictions on production capacity, the number of troops equipped with it is not large. In order to use these missiles on the blade, they were not used in previous battles with the Second and Third Pole Awakened.

All the fourth-level birdmen, including the one that appeared to be a fifth-level birdman, all descended to a height of three thousand meters at this time. After the number of birdmen in the sky was greatly reduced, the factor of interference was reduced, and the air defense units also carried out man-portable anti-aircraft missiles, locking on the fourth-level birdmen wandering at an altitude of 4,000 meters.

Under the guidance of the perceiver, the air defense troops locked onto the strongest birdman of the nine heads, and more than 20 "Red Flag" anti-aircraft missiles carried the hopes of countless people, and flew into the air with flames.

At the same time, the fourth-level birdmen also cast their own ultimates in the air. Compared with the three-pole birdman, the preparation period is longer and the launch speed is slower, the fourth-level birdman's ultimate move is not only powerful, but also has a shorter interval between attacks. In just three seconds, the Nine-Headed Birdman unleashed twenty-one different attacks—including twelve blue-white fireballs, eight high-density and high-compressed frozen gas, and three ball lightning.

"Attack of the fourth-level birdman!"

Lin Feng shouted loudly on the portable communicator and called the whole army to the police. All the evolutionaries on the ground, ordinary officers and soldiers, and half-awakened people, were all extremely nervous at this moment. The nightmare legend of the ability of the fourth-level awakened person has long been widely spread, even if he thinks he is a three-pole evolutionary or a three-pole semi-awakened person, he does not dare to take it lightly at this moment.

"Meow"

Yuan Chuyu raised his head and looked at the sky, nervously guarding Lin Feng's side. As soon as this catwoman policewoman entered the army, she was regarded as a confidant by Lin Feng, and now she has replaced Wang Chao and Du Lei as his bodyguards.

Niu Qi's six semi-awakened people who formed a small group also stared at the twenty-one attacks from the sky at this time. The Half-Awakened are amazingly powerful, but they are also helpless against this kind of birdman who is high in the sky.

In the face of this kind of birdman, who has taken advantage of the geographical advantage and mobility, the human side seems to be very passive, and no matter how strong the evolutionary is, he can only pin his hope on the anti-aircraft artillery that is still roaring endlessly and the more than 20 anti-aircraft missiles that have just been fired.

The first to fall were three ball lightning, which hit two 100-mm anti-aircraft guns one after another, fortunately the shooter who operated the gun had a lesson from the previous one, and the ball lightning that rolled along the barrel of the gun body was extremely fortunate not to cause the ammunition on the shell rack to detonate, but fell directly to the ground, blowing up two small craters one meter deep in the mud.

The third spherical lightning bolt was "sucked" by a tank, detonating the ammunition compartment, and the old Type 69 tank was killed on the spot, and the entire turret flew into the sky, killing and injuring many nearby soldiers with flying shrapnel.

Less than a second after the ball lightning landed, more than 20 portable TV-guided missiles launched earlier also approached the birdman, and the birdmen were also vigilant against these foreign objects flying from the ground at high speed, and they flapped their wings and made all kinds of beautiful dodge maneuvers in the air like a ballet, and their movements were so beautiful that all the fighter plane design masters on the earth were ashamed.

Nine-headed birdman, 25 anti-aircraft missiles in the air played a short "run, run and catch", some missiles mistakenly hit the auxiliary car, hit the ordinary three-pole birdman, some were freed by the birdman to take off the rake, and some directly hit, the metal jet released by the special shaped energy blasting warhead easily penetrated the bird's insufficient protective force source cover, and beat the birdman into a "landing chicken". Of course, the two fourth-level birdmen "shrewd" suddenly dived at a low altitude and got rid of the missile's pursuit, but they were instantly covered by the saturated fire of the ground anti-aircraft guns that had been prepared for a long time, and exploded directly into a ball of blood in the air.

In just a dozen seconds, eight of the nine high-level birdmen were shot down, and at the same time, the other eighteen attacks that the birdmen smashed from the air also landed.

The frozen gas emitted by the fourth-level birdman with the source force is highly compressed and dense, and the escape after passing through a high distance of three thousand meters is not obvious. Fortunately, the characteristics of frozen gas are the best defense, the water control type evolver and the telekinesis cooperate, the water control zhì forms a hemispherical protective shield above, the water freezes when it is cold, and the water cover becomes an ice cover when it encounters freezing gas, and seven of the eight groups of frozen gas are successfully resisted, and the last group hits two ordinary soldiers carrying cannonballs, instantly freezing into two lifeless ice sculptures.

What was really terrifying was that the twelve groups of flame bombs that were fueled by the source force automatically decomposed and escaped in the air after flying for more than a thousand meters, and each ball of blue flames with a diameter of ten meters decomposed into hundreds of fist-sized blue fireballs, turning into an out-and-out "meteor fire shower" and smashing to the ground.

This kind of flame released with source power, the temperature is high, and it is more immune to mental power protection, coupled with the all-round attack of the "map cannon", in the face of the blue fire rain falling from the sky, the position of the 77th Brigade was in chaos, and many people were hiding everywhere with their hands and feet. What made Lin Feng speechless was that in the small group led by Niu Qi, there was a semi-awakened person who was an earthworm man, as soon as he fell to the ground, he drilled a hole in an instant, and the whole person disappeared to the ground in just three seconds.

"Reach me! Don't leave me ten meters! ”

Lin Feng let out a loud roar, stretched out his right hand and pulled Yuan Chuyu to his side, hearing his roar, the nearby evolutionaries also approached him. What made Lin Feng speechless was that the person who reacted the fastest among these evolutionaries was actually Xiao Bailan. When Lin Feng shouted "Hold on to me", this little brother rushed over and hugged his "thighs" with a reaction speed of "no room for hair".

Guarding next to Zhao Qingfeng and Zhu Ming's gun positions, Lin Feng manipulated a puppet awakened person with both hands, and at the same time, his perception was fully expanded, and he tried his best to calculate the trajectory of the fireball that might hit his head and the time it landed. By this time, more than 40 "evacuees" had gathered around him. After this period of time together, Lin Feng's computing ability had long been famous, and the soldiers and evolutionaries who fought with him knew that in such a situation, his side was the safest.

The blue rain of fire fell from the sky, and Lin Feng originally thought that he only needed to resist the fireball within a radius of ten meters from his body. But when he calculated the trajectory of the fireballs that fell around him, he instantly broke out in a cold sweat. The place that Lin Feng was guarding was an anti-aircraft artillery position, with several piles of ammunition placed around them, once they were hit by this source force flame, the consequence would be a terrible explosion of ammunition.

"birdman!"

He wanted to be a little lazy, but now he has to pick up his spirits and deal with it with all his might.

Mental power, water wall, ice cover, dealing with this kind of source force flame is almost ineffective, and the best way to deal with source power is the same source force.

The more Lin Feng used the power of the source, the source power he could use at this time was only a line of source force with a thick thumb, and the length was only twenty meters. Fortunately, the ammunition in this anti-aircraft artillery position was stacked very closely, and it was barely within the range of his ability.

Lin Feng ran to the ammunition stacking point, followed by a bunch of companions who couldn't help. The blue fire rain fell, and the manipulation of the source force line turned into a spiritual whip in Lin Feng's hand, and every threatening flame that fell, it was accurately hit by his "whip", and it flew to the empty seat where no one was in the air.

The source force line in Lin Feng's hand was originally an invisible "line" with the naked eye, but at the moment of contact with the fireball, the "whip sheath" was ignited, and the invisible "whip" began to appear.

One regiment, two regiments, three regiments

Every time he made contact, the source force in Lin Feng's hand had to be shortened, and in just two seconds, Lin Feng intercepted twelve blue flames, and the original twenty-meter-long source force line was also burned less than fifteen meters long. By the third second, he had not been able to move his body to extend the distance in order to stop the flames that had smashed into the ammunition pile.

Nineteen, twenty, twenty-one!

By the fifth second, when the last flame was pulled away by him less than five meters from the ammunition pile, the whip in Lin Feng's hand was less than ten meters short.

On the position of the 77th Brigade, the sound of ammunition explosion resounded

Lin Feng could hold the anti-aircraft artillery position he protected, but he couldn't hold this huge battlefield V
