The "silent" cruising state of the mecha is to turn off all external systems such as positioning, radar, automatic defense system, etc., and be in an ideal "stealth" state, and use the spare engine to travel with the lowest consumption. This is usually used for small-scale ambushes, raids, or turnarounds of mech groups.

Of course, it can also be used when mech scouts are deep behind enemy lines on missions. Due to the fact that the surface of the mecha is generally used with composite coatings that absorb light, prevent radar and detect thermal energy, the mecha in the "silent" state does not exist on top of the opponent's large-scale detection instruments, and once launched, it has strong attack and destructive power.

The fly in the ointment is that the "vision" and "hearing" of the silent mecha are limited, similar to ordinary people, and avoiding or even crossing the other party's cordon is the first problem to face.

"This grenade-style thing is 'dust settled.'" The senior instructor said as he typed in the command on the console.

I saw that in the formation of the zigzag group, a warrior mecha led by a warrior mecha took out a grenade launcher from the leg side card slot and slammed into the front end of the electromagnetic assault rifle.

Boom!

A grenade streaked a parabola through the air, leaving behind a cloud of smoke in the shape of an airplane. In less than a minute, the smoke drifted away with the wind.

Instructor Gao gave his split-screen link to the warrior mecha on the left and right, and continued: "After zooming in, you can clearly see that these small particles like coal ash are our 'dust', which is a bionic technology product, and its main purpose is passive detection of regional vibration. These thorny hooks on the particles help the 'dust' to adhere to various objects for a long time. This is also the origin of the name 'Dust Settled'. ”

"The effective monitoring area of 'Dust Settle' is within three to five square kilometres, and the effective duration is between 21 and 27 hours. So, the question is, how can this particle, which is almost imperceptible to the naked eye, pass through safely with such a wide coverage and high sensitivity? ”

The avatars of Long Jie and Zhang Xiao came on the split screen on both sides.

"If time permits, drive small groups of beasts through the area and expend the energy of these 'dusts' at an accelerated pace. In this way, after three or two times, there is a time lag before the next blockade of the area by the other party, and it should be safe to pass. Zhang Xiao gave his own thoughts, focusing on the time limit of "dust settled".

"Well, taking advantage of the characteristics of the jungle area, good idea. However, if the monitoring personnel are experienced, this situation will be regarded as an anomaly, after all, the beasts have a strong sense of territory. Instructor Gao briefly commented on Zhang Xiao, looked at Long Jie, and asked directly, "You won't come to remove your armor again this time, will you?" If a bare machine enters an enemy-occupied area, it is basically tantamount to looking for death. ”

"If you're pressed for time, I think that's probably the case." Long Jie pondered for a moment, and then responded.

I saw a warrior mecha break away from the zigzag detachment, take a few steps forward, unload two pieces of armor from the left and right sides, grab them in their hands, and prop them up in the mud, and then "crawl" forward on all fours, hunched over, and staggering forward.

The senior instructor raised his eyebrows and looked at the main screen, where the monitoring system had already begun to analyze the data sent back in real time.

The crawling warrior paused at this time, released his armor with his right hand, unhurriedly took out a handful of wet mud on the mud floor, and threw it behind him with a snap, only then he re-grasped the armor and propped it on the mud ground, and turned around.

"This is an imitation of the Kodoki beast...... "The senior instructor laughed, "I actually came up with such a method." ”

"Quite creative! Medium-sized beasts, with large limbs, often divide their territory by feces and urine. Instructor Gao commented simply, with his usual strict style, a sentence of "quite creative" is already a high evaluation.

"Instructor, how do the regular troops deal with such a situation?" Zhang Xiao seems to be accustomed to his own "throwing bricks and attracting jade", and directly asked what he cared about.

The instructor typed in the instruction again.

The Warrior Mecha fired another "Dust Settled" with an electromagnetic rifle in his hand, but this time in an almost perpendicular direction to the first one, forming a cross.

The second "Dust Settled" swept over the large canopy of trees and soon fell into the depths of the jungle.

"This requires a certain amount of experience, because the area blocked by the 'dust settle' will inevitably be followed by an observation post, and only after the location of the post can we determine the direction in which we launch the 'dust settle', the height, and so on. A short-term energy field will interfere with each other between the intersecting dust particles, and if they pass through the intersection area quickly, the other party's monitoring system will not be able to make an accurate judgment, because this interference is similar to the strobe of the screen, which is extremely difficult to distinguish. It is only a few tens of meters away from the other party's monitoring area vertically. After the dust is dropped, it will break and disintegrate under a small impact, and its materials are varied, such as jungle terrain, and the material after fragmentation and disintegration is the food of most insects. In some cases, ice cartridge casings are even used as a carrier of dust. This can reduce the chance of being detected by the other party. ”

"Of course, that's just the usual way. Nuclear forces are able to sense the energy field of 'dust-settled' particles, and a 'blind male' method is usually used. Specifically, all the dust particles are attached to objects such as tree branches, and the dust particles are directly passed through the area by interfering with each other. ”

"Okay, let's talk about it first. Let's play a little game of peek-a-boo. Instructor Gao gave a split-screen link to himself to Long Jie and Zhang Xiao, and continued: "Now that I have sealed the entrance to this valley with 'Dust Settle', I will give you ten minutes to hide, limited to the valley. I'll be hunting you for half an hour. I'll get a reward for any of you who can survive half an hour! ”

"Raid?" Long Jie suddenly asked, "Instructor, can we resist after being discovered?" If you can, maybe you can hold on for a few more minutes. ”

"Hey! Of course! The senior instructor sneered, "But, believe me, it won't be that 'a few' minutes longer." ”

........

In the depths of the jungle, a figure could be seen coming from high and low.

A large number of branches and leaves were swept apart, and a young man in jungle camouflage stepped on the outer figure-eight steps, winding forward along the waist-thick trunk of an ordinary person, and swept rapidly. Occasionally paused to look back in the direction of the valley behind him, trying to calm his rapid breathing, and the sweat on his forehead fell a lot.

After raising his head and taking a sip of water, moistening his lips, the young man stuffed the military kettle into the military backpack and put it away. Frowning and groaning for a moment, the boy shook his head violently, let out a light breath, and rushed forward again.

Leaping forward, he grabbed the dark vine with the thickness of his arm in front of him with one hand, and swung forward; Changing hands in the air to grab another vine, he used his waist and abdomen to swing forward again. After a few ups and downs, the camouflage boy landed on the branch of another towering tree and continued to run wildly.

Soon, the camouflage uniform was once again integrated into the jungle environment, as if it had never been seen before.

Nearly a minute later, a Warrior mech burst in with a cruising walking stance. The chirping of birds and insects that had not stopped before fell silent, except for the faint chirping of a two-story mech hunched over the mossy and dead leaf humus, or the crisp sound of a branch breaking as the alloy dagger in the warrior's hand slashed through thorns.

Walking into a small clearing, the warrior stopped, and two small drones rose from behind him, surveying in circles.

Soon, one of the drones captured a series of footprints from a high place, following the trail downward; The other came back from a distance, and soon found a few vines that had been "handled" by someone.

"Good boy, aren't you determined to become the heart of a mecha? Why are jungle field skills not weak? Not very old, a lot of miscellaneous studies! The senior instructor stretched and zoomed the image on the split screen, and said to himself: "It's a pity, you should have found out, I'm getting closer and closer....."

The Warrior Mecha retracted the drone, chose a direction, and moved silently.

After a while, there was the sound of rushing water ahead.

The warrior continued to advance for dozens of meters and stopped.

A horizontal river rushes in front.

A clear line of footprints stretches to the river.

The two drones rose into the air again, heading for the upstream and downstream of the river.

The warrior stooped down and examined the footprints as he walked along.

"This section was walked back backwards, and when I got here, I took a pole jump from a branch and came to this big tree...... The scratches left when dragging the branches up here......" The senior instructor continued from some clues that were trying to go back: "The angle of the scratches is wrong! Here is the hoof prints of an adult male Kodoki, wandering here, lured by something...... Riding on the back of the Kodoki beast, with a twig that left a scratch here......"

"Good boy! What a cunning rabbit! If I really focused on searching this tree, I could at least buy this kid half a minute more! Instructor Gao couldn't help but slap his thigh, shook his head and sighed: "It's just a pity...... It's a pity......"
