: There were only ten of them, and in the first twenty seconds of heavy shelling, the little yellow-feathered birdmen were shot down.

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

Realizing the threat posed by the Yellow-Feathered Birdmen, Lin Ban immediately saw them as an important target. Soon, under the guidance of the perceiver, most of the anti-aircraft artillery battalion's anti-aircraft guns were all pointed at this 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? small

This judgment made Lin Ban very shocked. Relying on the Shame Puppet Technique, Lin Feng was confident that he would defeat any fourth-level awakened person, but after fighting against the fifth-level thunder beast and seeing the fighting method of the form change, he understood that he was hard-hitting, and he was not the opponent of a fifth-level awakened person in any case.

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 knife brigade on the ground, after clearing most of the birdmen, also moved out of the last trump card at this time.

The Red Flag Force Shoulder-Carrying Individual Anti-Air Missile, this missile was urgently developed after encountering the crisis of the fourth-level awakened, using the latest television guidance method, using a special shaped energy armor-piercing warhead, in today's production is damaged, subject to strict restrictions on production capacity, the number of its equipment troops is not much. In order to use these missiles on the blade, they were not used in previous battles with the Awakened Ones of the Second and Third Levels.

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 troops also carried out individual man-portable anti-aircraft missiles, locking on the fourth-level birdmen wandering at an altitude of 4,000 meters

Under the finger of the perceiver, the air defense forces locked on the strongest birdman with nine heads, and more than twenty "red flags." Anti-aircraft missiles, carrying the hopes of countless people, soared into the air with flames.

At the same time, the fourth-level birdmen also cast their own ultimates in the air. Compared with the third-level birdman, the preparation period is longer and the firing speed is slower, the fourth-level birdman's ultimate 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 Ban 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 a fourth-level awakened person has long been widely spread, even if he thinks he is a third-level evolutionary or a third-level semi-awakened person, he does not dare to take it lightly at this moment.

"Goo"

Yuan Chuyu raised his head and looked at the sky, nervously guarding Lin Ban's side. As soon as this catwoman policewoman entered the army, she was regarded as a confidant by Lin Ban, 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 bolts, which hit two old ones one after another. Millimeter anti-aircraft guns, fortunately, the shooter who operated the gun had the previous teaching, and the gun was out of position half a second early, and the ball lightning that rolled along the barrel of the gun body was extremely lucky 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 flash was "sucked" by a tank, detonating the ammunition compartment, and the old 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 for these foreign objects flying from the ground at high speed, the birds showed alarm slowness, they flapped their wings, and made each other in the air like a fan lei. Yao Yao's dodge maneuver is so beautiful that it is enough to make all the master designers of fighters on the earth ashamed.

Nine-headed birdmen, twenty-five anti-aircraft missiles played a brief "run-and-run-catch" in the air. "Some missiles hit the auxiliary vehicle by mistake and hit the ordinary three-level birdman, some were freed from the rake by the birdman, and some were directly hit, and the metal jet released by the special shaped energy blasting warhead easily penetrated the bird's insufficient protective power source force cover, and the birdman was beaten into a "landing chicken". Of course, there are also two fourth-level birdmen who are "shrewd." Suddenly, a low-altitude dive escaped the pursuit of the missile, but it was instantly covered by the saturated fire of the ground anti-aircraft artillery 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 by the source force has a high temperature, and it is more protective against mental power, and in addition, the all-round attack of the "Didan Cannon", in the face of the blue fire rain falling from the sky, the position of the sword 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.

"Draw on me! Don't leave me ten meters! ”

Lin Ban roared, stretched out his right hand and pulled Yuan Chuyu to his side, hearing his roar, the nearby evolutionaries also approached him. What made Lin Ban speechless was that the person who reacted the fastest among these evolutionaries was actually Xiao Bailan. When Lin Feng shouted "Move closer to me", this little brother thought, "There is no room for it." The reaction speed rushed over and hugged his "thigh".

Guarding next to Zhao Qingfeng and Zhu Ming's cannons, Lin Feng manipulated a puppet awakened person with both hands, and at the same time, his perception was fully expanded, calculating 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 time together, Lin Ban's computing ability has long been famous, and the soldiers and evolutionaries who fought with him know that in such a situation, his side is 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 ammunition that they were afraid of would be killed.

"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 the forest board uses the power of the source, the source force that can be used at this time is only a thumb-thick line of source power, and the length is 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 Ban's hand was originally an invisible "line", but the moment it came into contact with the fireball, the "whip sheath" was ignited, and the invisible "whip" began to appear.

One regiment, three 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 of the flames had been whipped away by him less than five meters from the ammo pile, the whip in Lin Ban's hand was less than ten meters short.

On the position of the Knife Brigade, the sound of ammunition explosion resounded"

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