Steel steam and flame

The reason why heavy sniper firearms have become recognized as a weapon against surgeons is largely due to the role of this type of firearm in history, which is to be used against thickly armored vehicles. Surgeons have largely replaced these thickly armored vehicles throughout history, such as heavy tanks and other weapons that still appear in small countries today.

The aerial cannon on the right side of the dragon's body rotated smoothly, and the nearly three-meter-long muzzle flame spread out. In the afternoon light, the forest canopy below it was also coated with a faint orange light. There is no obstacle in front of the bullet flow. The dragon relies on the dragon to capture the source of the sound and use its body muscles to control the muzzle direction of the six-barreled aerial cannon. The dark green ancient branches and leaves instantly turn into pieces and fly in the air.

A large pile of bullet casings fell down, and a small hole took shape in a short period of time, connecting the sky and the forest below, which were blocked by the tree canopy, and the dim air inside was visible.

"Boom..." This time, the dull sound spread and truly entered the ears of the dragon knight Nichols who reacted. The aircraft cannon on the right side of the dragon's body turned into scattered fragments without any surprise. The bullet chain fell off and was dragged out for a long time.

The sound of heavy sniper rifles did not stop, but the last thing Nichols could hear was the huge metallic sound of the warhead hitting the armor on the dragon's body. The remaining few people subconsciously squatted down and moved closer to the safest place between the dragon's wings.

The huge size of the dragon has now become the most obvious target, and it can be accurately hit without any need for precise aiming. At this moment, Nichols took a few deep breaths on his back and finally calmed down.

"There are also usable weapon modules, but those are not used to deal with close-range targets. The enemy has heavy weapons in his hands, but to this armor that can resist aircraft cannons, it does not pose a serious threat. It is just an irritating sound. . What needs to be done now is to determine the enemy's location and number, and then link up with the ground team in the distance to achieve the purpose of annihilation." Nichols is a dragon knight after all, and the blood splashed by his teammates around him reminds him that he needs to maintain Calmness in the head.

While thinking, Nichols removed a small piece of the armor on the dragon's back, revealing several black scales. He took off his gloves at the same time, immediately pressed them on a piece of warm scales, and closed his eyes.

Mentally connected to this, a smile appeared on Nichols' lips. He is a dragon knight. If the enemy really thinks that his attack method only relies on those weapon modules, then the enemy's subsequent results may not be so good.

The dragon's field of vision is nearly 360 degrees, and the only blind spot is the central axis of the long spine, which is also the middle of the wings. There are many differences from human vision. In addition to basic things such as color, Nichols, who is connected to the spirit of the dragon and can share his vision, can directly see a wide range of temperature distribution maps. This is his own temperature perception ability. In addition, its viewing distance and discernible clarity, and its ability to capture weak light, allow him to distinguish the veins of dead leaves on the ground.

There was no need to move his eyes. The moment Nichols entered the dragon's field of vision, his line of sight automatically focused on the empty area that the aerial cannon had just fired.

The scene was similar to yesterday, except that there were still a few unbroken branches on the lonely old tree. Broken leaves and exploding sawdust were flying randomly around the ancient tree due to the flapping of the dragon's wings. The focus of the line of sight was on a bifurcation in the middle and upper part of the ancient tree. The enemy, who had not been harmed at all, was wearing an alloy mask and stepped barefoot on a fresh crater made by an aerial gun bullet. He held a heavy sniper rifle in his left hand and carried it on his shoulder, while his right hand was spinning a revolver, looking very leisurely.

Feeling the sight, Nichols saw the enemy stop turning the revolver in his right hand, and the moment he held it, they met like old friends and waved to him. Immediately, before Nichols could come out of this ironic scene, the muzzles of heavy sniper rifles and revolvers were already aimed at the dragon, and sparks from the canopy bloomed on the dragon's armor the next moment.

The calm mood was completely shattered by the sound of metal collision, and Nichols roared angrily, but the enemy standing on the branch had already fallen and disappeared behind the trunk.

The dragon's steadily flapping wings instantly folded in, and its hovering body swooped down in a falling posture. At the same time, the giant dragon opened its mouth, and the armor on its neck made a clicking sound as its flesh and scales squirmed.

"Buzz..." The transparent sound was like ripples on the surface of a lake, coming from the dragon's mouth. The circles grew from small to large, swinging forward at an extremely fast speed. The sound wave brought out a series of violent explosions in which the air was extremely compressed. Except for the trunk of the ancient tree, almost everything in its path was turned into powder in the sound wave with huge energy.

"The first one is the same sonic attack as mine. The advantage brought by the size increases the destructive power dozens of times." Cassia exploded with speed, and her body was full of danger signals. The moment he was caught up by the sound wave again, he hid behind an ancient tree and avoided most of the impact.

As someone who already uses sound waves, Cassia's theoretical research on sound waves cannot be said to be very in-depth, but he is still qualified to become a researcher. This kind of sound wave attack does not have strong penetrating properties. It is completely a destructive ripple using air as the medium. As long as it does not come into direct contact with it, it will not be seriously harmed. It makes more sense to think of it as a corrugated air cannon activated by sound.

The eardrum was vibrating violently, and Cassia immediately recorded the second item: "With a huge noise, if the eardrum is not protected in advance, the vibration will be enough to damage it, which will affect the balance of one's own movement."

The tremor of the sound wave disappeared at this moment, Cassia opened the cross pupils directly, and instantly jumped forward dozens of meters away. There was an explosion behind him almost simultaneously, and within a small area, the impact shook the ground.

After the sound, a high-density air column with a diameter of five or six meters took shape in front of the dragon's huge open mouth, hitting the roots of the ancient tree where Cassia was just now. At the moment of contact, the impact and compression into solid air released all the energy, blasting the entire roots of the ancient tree into pieces, and sending up a fierce hot wind that was close to Baidu. Countless dead leaves were rolled up and hit Cassia's back. The fallen ancient tree caused the canopy of this area to shake together.

"I don't know if it is possible to create the ultra-powerful low-pitched waves that existed in the Brino region at that time, and directly detonate the unstable platinum gunpowder. But the destructive power of the air cannon formed by compressing air with high-frequency sound is indeed terrifying." Third. The article has been written into Cassia's head, "I use high-frequency sound waves myself, and the compressed air is only as powerful as ordinary bullets, but when used by dragons, it is comparable to aircraft bombs. But this kind of attack is obviously not as fast as ordinary bullets. If it is not hidden and used out of the enemy's attention, it will have no obvious effect."

The destruction of each primary dragon is extremely shocking, but this dragon is obviously limited by the dragon knight combined with it. Cassia believes that allowing the dragon to attack freely may pose a threat to itself. Being guided by the spiritually connected dragon knight is actually a limitation, or it might as well be seen as a burden.

But Cassia also understands that between being controlled and not being controlled, most of the choices are the former. This is the same as the military school will deal with those who have more than 16 inhibited tubes among the freshmen. The unstable factor is disliked by many people.

The distance between him and the dragon could no longer be increased. Cassia waited for the dragon knight's follow-up attack, and he also pulled the bolt of the heavy sniper rifle, preparing to help the dragon knight further increase his anger. Because if this dragon knight does not let the dragon lower its height, he really has no chance to kill them except using his breath.
