Zero Leap runs into the mine, reaching for a special grenade the size of an egg from the carrying gear behind him.

This grenade is called a sonar mine, and it does not explode and does not have any lethal power. However, when the sonar mine is activated, it emits ultrasound waves to scan the current environment. The Doomhammer Warrior's standard tactics sheet allows you to model your environment by receiving feedback from the sonar to provide a clear display of the terrain.

Generally speaking, sonar mines are mainly used in environments with complex structures. For example, the mine tunnel in front of Zero.

After pressing the start button of the sonar ray, Zero threw the little thing out. A special grenade in the shape of an oval bounces to the ground, and after the red signal light flashes three times in the center, the sonar thunder splits apart on all sides, forming a pocket-sized launcher. In the next moment, invisible sound waves emanated from the little thing, propagating through the air at a speed of 340 meters per second, speeding through every space of the mine.

Zero opened the tactical table on his wrist at the same time, and the tactical table received feedback from the sonar, and there were cyan lines on the black screen background to quickly build a mine tunnel pattern that extended in all directions. Suddenly, the complex topography of the mine road had been memorized in Zero's mind.

Behind him, dense footsteps sounded. Zero didn't hesitate any longer, and flew into the depths of the mine.

Although this abandoned mine has been transformed into a base by wolf thieves, with the economic and technological strength of wolf thieves, it is impossible to carry out in-depth transformation of the mine after all. In addition to repairing the lighting system, the wolf thieves also built improvised shantytowns around the mine, as well as repaired some of the mine tunnels in the outskirts to serve as temporary parking spots for supplies.

As a result, the coverage of electricity ends in these places. And Zero went deep into the mine and was out of the scope of the wolf thief's transformation. Chasing Zero into the mine, the team led by Soldier Sander was faced with a black pressure after crossing the power coverage area, as if there was no end to the mine.

On weekdays, even wolf thieves rarely go deep into these mines. Sander was also aware of the intricacies of these tunnels, and that due to disrepair, some of the tunnels had loose fixed frames and several cave-ins were closed. Therefore, there are too many dangerous factors in the mine.

But Kazuo Biandu's order could not be carried out, so Sander made a gesture, and the members of the team immediately dispersed, and everyone put on night vision goggles. In infrared vision mode, they are able to see clearly even when there is no illumination. It's not that the team doesn't carry lighting equipment, but if they use lighting tools in the dark tunnels, it's no different from a live target.

The mine was excessively quiet, except for the occasional sound of water droplets hitting the ground in the distance. Each member could barely hear their own breathing and heartbeat, and the atmosphere was very oppressive. But they are all soldiers who have been hovering on the line of life and death for many years, and all of them have excellent psychological quality, and they do not have any impact because of the repression of the environment.

Sander was more like a patient cheetah in the dark, and he cautiously allowed his soldiers to advance in a V-shaped queue so that even if the opponent attacked, he would give the soldiers a buffer. And Sander himself served as the top soldier of the queue, and he walked at the front, half-bent on his waist, and landed silently.

At that moment, a jumble of voices rang out at the front of the procession. It sounds like the sound of a metal can rolling on the ground, but judging by the loud echo in the mine, I'm afraid the weight of this "can" is not light. In night vision mode, Sander soon saw a dark shadow rolling in the distance. When the thing came to a distance of about thirty meters from them, the distance made Sander see that it was an iron bucket.

In the air, the smell of diesel was heard. Tander's face changed, and he yelled: "Avoid, that's an oil drum!"

The voice fell, and the oil drum exploded. Suddenly, the mine road shone brightly. The soldiers in night vision mode were immediately blinded by the intense light of the fire, and Sander rolled from the ground to the rear, while the gunfire of automatic pistols rang out frequently.

Angry shouting, screaming, gunshots, and screams played a chaotic tune. When the flames of the oil drum explosion faded, Sander took off the night vision goggles, only to see that three soldiers had already been shot and killed. All three soldiers were shot in the center of the eyebrows, and their positions were almost all in the same place, showing the enemy's superb shooting jishu.

Sander scolded and yelled, "Take off the night vision goggles and put all the guns on me!" Be careful yourself, the opponent is a cunning rat, now, let's kill him!"

The soldiers responded, taking off their night vision goggles and attaching gun lights to their machine guns, as Sander had said. In this way, although the goal is obvious, it will not be caught off guard by the opponent using strong lighting.

After changing their equipment, the members of the Gang are bent on their waists and constantly move quickly behind cover in the mine, such as abandoned minecarts and signs. After 10 minutes of such a rapid march, under the light of the gun, a figure flashed and drilled into the left side road.

"Chase!" Sander yelled, scurrying into the branch first, and immediately saw the figure running forward. Without saying a word, Sander slammed the trigger. The machine gun in his hand immediately erupted a tongue of fire of half a meter, and the metal torrent composed of bullets swept towards the figure in front of him like a blazing whip.

Da Da Da -

The members who caught up afterwards raised their guns and fired without the captain's orders.

But the figure was so fast that he ran on the ground and on the wall of the tunnel. The firepower of Sander and others is always one step slower than him. The bullet is like a bee that sees honey, but no matter how hard the bee tries, it can't touch the sweet honey.

When the figure in front ran to the heart of the mine, the figure twisted slightly, and another shadow was separated. The two figures swept left and right towards the mine in the opposite direction, and Sande's eyes were about to fall.

", it's a paranormal! I knew it wasn't that simple. ”

Xander immediately named four soldiers from the ranks, and took the other three with himself. The two teams split up, and Sander and the others got into the side road on the right. But he didn't go far before he found that the mine had already collapsed, and there was no figure in front of him. The obstacles of the collapse were so tight that even rats, let alone people, could not climb over them. Seeing this, Sander immediately knew that he had been fooled.

"Quick, quick, let's go back!" said Tander, directing the team back.

But before they could get out of the fork in the road, they saw a constant flash of fire in the mine tunnel ahead, accompanied by gunfire and screams.

The sound of no more than 5 seconds before and after, the sound of gunfire, shouts, and firelight disappeared at the same time. The mine tunnel ahead immediately became dead silent, and Sander gestured for the team to be quiet and press the lights to the ground. Maintaining this quiet march, the four of them quietly pressed in the direction of the gunshots.

After walking about ten meters, Sander heard a strange time.

Didi Didi――

It's like the sound of an electronic jumping needle, and the frequency of the sound is getting faster and faster. Sensing something was wrong, Sander looked around and spotted a device on the walls on either side of the tunnel. It was a pitch-black box, and a red signal light was flashing in the center of the box. The sound was made by the signal light, and now, the frequency of the signal light flickering is almost insane.

A drop of cold sweat slipped down Sander's forehead, and the black man lost his voice and said, "It's not good, it's a time bomb......"

Before the words fell, a fire suddenly exploded in the black box. As far as Sander's eyes could see, there were flames in all directions!
