The Karaya Tiger runs through the ruins outside the city of Larkin Bede. Its four thick flesh-padded paws landed silently, but with incredible speed, weaving through the rubble and rubble, almost turning into a blur of shadows.

It has been frolicking and hunting in this almost endless ruin since it was born, and now it is back here, like a fish in water.

Li Mu's legs clamped tightly around the back of the Kalaya tiger, and grabbed the fluff on its back with both hands. The Calaya Tiger has a large undulation of the spine when running, and it is not very comfortable to ride, but the speed is much faster than the previous motorcycle. At full speed, the surrounding scenery turned into a blurry phantom.

"It's almost there."

Li Mu looked at the familiar terrain. Two months ago, he and Li Mei had just arrived in Lakin Beed, and the scene of being chased and killed by the red-eyed toad was still vivid.

Li Mei put her hands around his waist and sat behind him, facing the oncoming wind.

"I miss grandma so much, she will be very happy to see you become the fourth energy level."

Li Mu was a little delirious, and he was still worried about the son of Hubisega. I don't know if the Amerikens will be able to get rid of him.

At this moment, a powerful, cold, and violent spiritual force wave shot from the east, sweeping across the airspace within a radius of dozens of kilometers.

The two involuntarily shuddered. Even the Karaya tiger stopped running, the fluff on its back exploding like a hedgehog. The claws bounced out of their sheaths, clasping the ground tightly. It sensed a powerful threat.

It didn't take long for two "boom" sounds in the sky, as if there was rolling thunder exploding in my ears, and my gums were numb. The glass in a radius of several kilometers exploded under this loud sound.

"Hmm!"

Li Mei's physical attributes are weak, she covered her ears, and only felt that her eardrums were about to be shattered.

"It's a sonic boom that happens when the sound barrier is breached, and it's very close to us."

Li Mu's face sank like water.

Sonic booms have a front excitation and a back excitation, the front excitation is relatively large, the rear excitation is relatively small, and if the distance is long, the rear excitation will be covered by the front excitation.

Li Mu urged the Karaya Tiger under his crotch to speed up and run towards the subway platform. His intuition told him that the owner of the spiritual wave just now should be the son of the Hubisega.

The Amerikens failed.

*****************

Simidi was flying at a low altitude of more than two hundred meters above the ground, his two pairs of psionic wings flapping at high frequencies and emitting a piercing humming sound.

The six J-9 attack planes of the 7th Army Aviation Regiment over Lakin Bede have been dismantled into parts by it. Because of their emphasis on low-speed performance, these attacks were shot down with little resistance in the face of the agitated and nimble Simidi as clumsy as ducks.

"Two more, thirty kilometers away, seem to have spotted me and are speeding away. Obviously not perceiving the mental force wave, interesting, can humans rely on other abilities to detect and locate? ”

In a fit of rage, he was still curious about human technology.

"But don't think you'll be able to escape death."

It is very difficult to increase speed to supersonic speed by flapping the wings alone, and even Simidi cannot do it. Because when the speed reaches the speed of sound, the air will be shocked because of its compressibility, creating a great resistance. When Simidi reaches the speed of sound, the speed of the tips of the two pairs of wings reaches the speed of sound before the body, and a shock wave appears.

At this time, the wings that provide power become the biggest source of drag, unable to drive the body to accelerate further. Even if the sound barrier is forcibly breached, all of Simidi's energy will be consumed in a very short period of time.

However, there are still a handful of powerful, mutated creatures that are able to break through the sound barrier, flapping their wings at subsonic speeds and using psionic energy to propel them forward at supersonic speeds.

【Jet Propulsion】

A dazzling purple light lit up from Simidi's two pairs of wings, and with a flap of his wings, his speed began to skyrocket.

The air compresses on the surface of Simidi's body, forming a shock wave that attaches to the surface of the body. The water vapor in the shock wave condensed into a cloud of mist under strong pressure. It's like putting on a white dress for him.

Eventually, he flew faster than the speed of sound, leaving the sonic boom behind him, slicing through the sky and chasing after the two attack planes.

Flying a distance of thirty kilometers, Simidi does not need even eighty seconds. It wasn't long before his powerful recovery could see the flames of the tail engines of the two attack planes, which were fleeing in a hurry.

Two J-30A in the middle of the high altitude.

Liu Qing was very calm, and did not get into a mess because of the harsh urging in the data chain. She first threw away the auxiliary fuel tank that mounted the fighter's lower belly, and then pushed the throttle valve, allowing the fighter to break through the speed of sound.

"Red Wing 2, use the PL-15 close-quarters combat bomb to interfere with that monster, don't let it take down the last two attack planes of the 7th Army Aviation Regiment. Otherwise, the surname Zhang will give us small shoes to wear. ”

The powerful power generated by the afterburner of the two WS-15Cs pressed her to the seat. She stopped accelerating when she was accelerating the fighter to Mach 1.5.

At 2 o'clock in the fighter plane, she was going around the monster's flank and rear, using the SD-18 medium-range air-to-air missile, to attack from behind.

There are many mutated creatures with the ability to fly, and their flight performance is very different. The most taboo thing about fighting them in the air is to get into a close-range dog fight with them when you don't have any information. If you encounter a mutant creature with supersonic hovering ability or excellent acceleration/climb ability, it is very likely that the ship will capsize in the gutter.

As an advanced short-range air-to-air missile, the PL-15 pays more attention to maneuverability, and the combat is a continuous rod warhead in the 11kg. A set of metal rods are connected end to end to form a metal ring. The compression is loaded in the warhead, and when it explodes, the shock wave generated by the explosives is instantly stretched to the maximum.

This kind of missile has good power in the face of enemy aircraft, and can even directly cut off enemy aircraft, but it is not so effective in the face of thick-skinned second-level mutant creatures.

The SD-18 medium-range air-to-air missile is different, this bulky missile, with a warhead of 75 kg, even a mutant creature of the second energy level, after a shot, will not be able to eat and walk around.

Simidi was locked on using the onboard phased array radar, and the altitude, distance, and angular velocity of Simidi began to be displayed on the heads-up display. At this moment, Simidi's speed reached Mach 1.6, and it was still accelerating rapidly.

Liu Qing's brows furrowed, and she smashed the Mutant Creatures Illustrated Book published by the Military Research Institute, memorizing the data of the flying mutant creatures on it. Very few mutated creatures can boast such superior flight performance. The AWACS aircraft had already searched the database, but it did not store any information about this monster.

Luckily, the monster seems to have near-zero radar perception, and even if it is locked, it does not make any emergency turns or other actions to get out of the lock.

This made her breathe a sigh of relief, if she was lucky, she might be able to deal with this monster in one shot.

Activating the SD-18 on the pylons on the left side, Shen Luoyan immediately tuned the missile's active radar frequency so that the missile could simultaneously receive the reflected signal from the airborne radar after launch.

After waiting for a while, a box appeared on the helmet sights of the two people in the fighter plane at the same time, jumping slightly, which was the target locked by the onboard radar. That is the target locked by the missile radar, and it is marked with a dot and coincides with the box.

Simidi has entered the missile's inescapable range.

"Don't launch yet, wait for the launch of Red Wing-2 before launching."

Liu Qing wanted to judge the maneuverability of the PL-15 by observing its movements when it dodged the PL-15. Moreover, after Simidi dodges PL-15, he will definitely lose a lot of energy, which can improve his hit rate.

"Missile launch!"

The voice of Red Wing 2 can be heard over the communication system. Then, a missile with a white tail of smoke appeared in the sky and flew head-on towards Simidi.

Shen Luoyan's palms were stained with sweat marks, and he watched as the missile drew an arc and intercepted it towards Simiti.

"It's not dodging at all?!"

She was amazed to see the triangle on the radar that marked Simidi, the trajectory was still a straight line, and there was no tendency to turn.

"Could it be that its supersonic maneuvering performance is so poor that it is unable to make large overload maneuvers at supersonic speeds? Or disdain to dodge? ”

Liu Qing also looked puzzled.

"Boom!"

With a flash of fire, the PL-15 hit the target accurately. (To be continued.) )
