The sonic pulses outlined the entire production hall, letting Kasia know where there were many machines and where there was an open space. I really wanted to increase the frequency of the sound waves and refine the outline of this drawing. The sheer number of machines and the structure inside the factory must consume most of the spirit.

Now is the time to be highly concentrated, and every bullet from the enemy, as well as every attack from the test subject, will cause serious damage to yourself before you enter the scale. Knowing this made Kasia's body tense, and the three subjects were attacking together through communication was also a situation he had not thought about. Improved, they have more abilities and stronger bodies.

"It just doesn't work well with that body. The test subjects gave Kasia this feeling, and their abilities and appearance during combat were closer to the zero encountered in the knight's squire assessment, but so far, not even one test subject had the breath of zero.

After advancing a few hundred meters towards the interior of the production workshop, Kasia came to a stop in the center of a small workshop. The semi-manual and semi-automated factories are far from the real large-scale factories in the empire. There are traces of operators everywhere, and most of the products transported and processed are material frames, etc., and the logistics system controlled by the differential machine only exists in the most basic prototype.

The spirit focused on selecting the image scanned by the sound pulse behind him, and the test subject was still at the front, and the follow-up support force seemed to be in a short break at this moment, and there was a hesitation of about ten seconds, and then they entered the production workshop in the form of a team.

Kasia, who was about to pull the distance a little further, stopped, turned around and pushed the moving parts of the processing machine next to him to the ground, broke the bolts, and pulled off a hard positioning line rail from above. The size of an adult's hand, the length of two meters, and its hardness, the destructive force caused by swinging is definitely much, much higher than that of the long shaft of the larger one.

This is a rare opportunity, Kasia is convinced. Ten seconds or so, combined with the gap between the enemy and the test subject, will be about half a minute before they arrive at this position to support. I don't know if the enemy believes too much in the power of the test subject, or if his performance is not very satisfactory in their eyes, Kasia didn't think about it carefully, but made it clear that within half a minute, except for the test subject who gave birth to the tail, one of the other two should stay here.

The triangular formation, which lacks Kasia's ability to detect the surrounding environment and terrain, makes the encirclement formation planned by the three test subjects unstable. It takes time to get around some places, and the extreme speed can only be used in the more open areas, and the visit to the busy machinery and the darkness in the workshop will inevitably affect them.

When the sound of "zizi" could be clearly captured by Kasia, the distance between him and the subject was no more than two hundred meters. Kasia went to capture the frequency range of the subject's communication more closely, and tried to make the same frequency of sound herself.

This seems to be due to the fact that he has accumulated a solid basic knowledge of himself, and it is also due to the fact that he has been using sound wave pulses to detect the surroundings for a long time, and the process of imitation is unusually natural, and the corresponding frequency range is analyzed, and the throat has changed when the consciousness has related thoughts. Kasia's ability to learn makes him a gifted imitator, and even if he doesn't know the exact meaning of those sounds, the large number of repetitive and meaningless sounds is a human interference. Looking at the sudden incongruity between the subjects, Kasia was sure that the subjects were correctly and clearly capturing the sounds they had made.

Immediately intensified, human interference immediately covered the three test subjects, and the fan-shaped encirclement pulled out by the triangle was quickly destroyed behind it. Kasia carried the rail to the nearest subject, moving her position towards the area where the machines were densely populated.

The distance was rapidly reduced, the sonic pulses returned to the frequency of detection, and under mind control, all the details of the environment within a radius of fifty meters appeared in Kasia's mind as a sketch-like image. It is known that the test subject is not much different from the rest of the enemies in the dark, except for the temperature perception and blood sensing. In addition, they also have a very fatal flaw, that is, they will not use and will not use firearms. There are no flares, no means to effectively create a light source, and relying only on temperature perception and strange sensing, the attack on Kasia in the current environment will be limited in many ways.

The approaching subject suddenly increased its speed at this moment, and disappeared in the blink of an eye at a distance of less than twenty or thirty meters. The cuticle of the sword in his hand slashed sideways at Kasia's head, but sparks flew in the middle of it. Subject was pondering what was going on, when only a whistling could be heard in the darkness, and the end of the line rail had already slammed into its jaw.

There was a crunching sound in the head, and the subject's horizontal sword slashed through the open pillar on the path of the attack, slicing through a field of pitch-black air. Instead of a violent impact, the subject heard Seven's words and quickly retreated, the line track catching up with him, hitting him in the jaw, and taking his head backwards in an exaggerated arc.

The subject quickly steadied his footsteps, and stepped backwards to lean forward, crossing his hands forward at the same time. The linear rail hits the center of the intersection and bends in the middle the next moment, and the subject is unable to resist the force, and when the linear rail bends at an acute angle, it itself has taken several steps back in a row. Before he could gain a footing, Kasia let go of the line track and burst into front of him, sweeping his feet away with a single kick.

The subject was about to fold itself into a ball, spun around and was about to land, and several punches in a row found the same landing point, hitting the side of the jaw. Kassia then kicked it straight away, and the subject spread out in the air, the sharp claws on its limbs grabbing into the ground to stop itself. Keeping moving, the subject moved his jaw, which had been misplaced by the heavy blow, and pressed his body against the ground at the same time, allowing himself to lunge towards the perceived position like a cannonball.

"Bell!" the clanging sound of metal clashing made Kasia smile. The steel section used as the roof pillar of the factory canopy was forced into a huge arc by the test subject, and the huge crack also spread horizontally from the point of impact. While the ground shook slightly, a small piece of hood shook violently.

Kasia stood behind the pillar, and it was clear to see that the subject had not hesitated to destroy the massive pillar as it tried to rush towards her. The top pillar absorbs most of the force, leaving the subject backwards. It was only one step to stabilize himself, and the shock caused by the impact on the inside of the body never appeared in the subject's head. Adjusting the direction slightly, the subject tried to get closer to Kasia again, and Kasia had already turned to his side, his fist whistling, and in a very short time, several punches found the landing point, and slammed it into the jaw again.

In the sound of "click", the frantically proliferating dragon tissue could not pull back the jaw that began to dislocate under the impact. Sharp teeth are no longer symmetrical and tightly bite, creating a finger-wide misaligned gap. The subject now grabbed Kasia with both hands, and stabbed his claws into his neck and heart.

"Bang!" A flash of fire appeared abruptly, and the subject's sharp claws, which had pierced into Kasia's body less than a centimeter, immediately lost all strength and stopped.
