It was already dark, and the abandoned factory built on the hillside seemed to be trembling faintly. Less than two kilometers away, rows of chariot mechs formed a huge fan-shaped array along the vast wilderness on either side of the lane. Between the billowing yellow smoke that had not yet settled, armored personnel carriers were slowly assembling from behind.

"Buzz......" A low roar was heard, and the siege tanks that had just stopped suddenly turned their turrets in unison. The armor on both sides of the chariot also underwent a series of changes, and four stout outriggers with groups of hydraulic pipes suddenly sank deep and smashed into the ground like jacks, slamming into the shape of the chariot. The barrel of the tank, which originally had a square muzzle, was raised high, and in a series of crisp sounds, it was transformed into a group of U-shaped guns capable of firing high-power plasma shells.

"Boom!" The Marauder mechs, who stood in an orderly manner between the siege tanks, also seemed to have received some order, and they stood up in unison, raising their arms equipped with Punisher grenades and rapid-fire lasers, and aimed at the abandoned factory that seemed to tremble slightly in the cold morning wind in the distance.

"Buzz!" Just as the chariot mechs were in formation, among the billowing smoke and dust in the rear, medical transport planes suddenly rose up and flew forward through the thick smoke screen.

The transports were carried by the Marines who had served as the first wave of exploratory attacks, and there were more than a dozen transport planes carrying hundreds of elite soldiers in full armor. According to the order of the commander-in-chief of the operation, Zhang Youzhao, these marines, who play the role of vanguards, will test the strength and layout of the agents hiding in the abandoned factory, and force their way into the base according to the situation.

Time seemed to stand still at this moment, and the roar of the engines of the transport planes seemed to be left between heaven and earth.

One by one, the pilots of the transport planes stared nervously at the movement of the abandoned factory on the holographic radar screen, pricking up their ears to listen to the grim radar sirens that might go off at any moment. The transport plane responsible for "persuading the surrender" was directly hit by a missile suddenly launched from that factory, and that scene made the pilots of these transport planes have been apprehensive, for fear that the factory, which seemed to have suddenly fallen silent, would suddenly take off a patch of anti-aircraft missiles.

"Buzzing ......" However, as time passed, the desolate and desolate abandoned factory still did not move at all, and not even a single moving figure could be seen.

"Plane 07 has arrived above the building on the left wing of the target and is preparing to deliver the first team!"

"Plane 29 has arrived at the gate area directly in front of the target, and is preparing to forcibly land and transport the fifth team!" ……

Moments later, the fleet of transport planes finally flew over the factory, and the communication channel immediately resounded with the sound of reports.

"Well, here we go!" Zhang Youzhao, who was sitting in the armored command car, looked at the group of holographic images transmitted back in front of him, nodded with satisfaction, reached out and took out a cigar, and lit it leisurely, like a VIP audience who was about to enjoy a Hollywood blockbuster.

"Snort...... The first team reported that no enemy armed personnel were found on the top floor of the target's left wing building, and they were preparing to search on the first floor of Xiangxia! Complete! ”

"The fifth team reported that no enemy personnel were found in the target gate area, and they are preparing to forcibly open the target gate! Complete! ”……

The first wave of tentative fighters landed unusually smoothly in the intended area, and the group of transport planes that had completed the mission began to evacuate the factory, and a series of reports from the attacking troops rang out. It was as if it had suddenly become an empty city, and the various areas of the abandoned factory were empty without a single figure. This strange silence made the Marines who set foot in the target area can't help but raise their hearts to their throats, and their intuition tells these soldiers that an invisible danger is lurking in this dead silence.

"Immediately connect to the holographic cameras on the armor of each squad leader!" Zhang Youzhao, who took a hard puff of his cigar, frowned slightly, and a trace of unpleasant premonition passed through his heart, Huo Ran sat up straight, and ordered the staff officer in a deep voice.

"Yes, Commander!" The staff officer replied proudly, and the huge holographic radar image screen immediately turned into a small screen of the same size, and the images seen by the Marine squad leaders who were entering the target area were immediately presented in front of Zhang Youzhao's eyes.

"The first team reports that they have entered the first floor below, and no enemy personnel have been found!" In the picture, the first team descending from the top floor of the building follows the dilapidated corridor to the lower floor, and the empty and dilapidated houses are immediately revealed.

"Wait, something doesn't seem right!" As soon as the words fell, the leader of the first team suddenly stopped and made a dangerous gesture to the team members who were cautiously searching forward beside him. More than a dozen well-trained marines of this squad immediately dispersed, hurriedly looking for the nearest cover, and nervously raised the assault rifles in their hands.

"Bang dang!" Just as these Marines were hiding their bodies, the air intake baffles of the front and rear ventilation ducts were suddenly kicked open, and a series of black and round objects were immediately thrown out, rolling into the crowd of Marines with a series of crisp metal crashing sounds.

"Grenade!" An exclamation suddenly sounded in the communication channel.

"Boom!" However, before the squad leader's exclamation could land, a fireball accompanied by a huge explosion instantly engulfed the entire corridor. The group of images representing Team 1 immediately turned into a snowflake, and the communication channel suddenly turned into a blind voice.

"Mines!" Just as the first team had an accident, there was also an exclamation from the fifth team approaching a factory building along an open area. Several anti-infantry high-explosive mines suddenly broke through the soil layer and flew to a place half a man high. Immediately afterward, there was a huge explosion, and the picture of the captain of the fifth squad also turned into a snowflake.

"There's an ambush!" At the same time, a squad that was about to pass through a large cafeteria in the factory was suddenly overpowered by a rapid rain of bullets, and the leader of the squad panicked and raised the alarm.

"Da-da-da, boom-boom!" In less than half a minute, a series of rapid and fierce gunfire stirred up the otherwise unusually dead factory. Holograms representing the ten squad leaders turned into snowflakes one after another, or stood still.

"First Squad, please answer when you hear it!" "Fifth Squad, please report the casualties immediately!" ……

Inside the armored command vehicle, the staff officers whose faces changed slightly hurriedly called out to the various marine squads in front. However, there was hardly any sound in the communication channel other than the noisy and intense sound of gunfire.

"No need to call! Pass my order, a cluster of combat vehicles of a heavily armored regiment, and in a minute carry out covering fire on the target area! The second wave of attacking troops, get ready to attack! Zhang Youzhao snuffed out the cigar in his hand fiercely, Huo Ran got up and waved his hand, and ordered loudly to the staff officers.

"Covering shots? Sir, our men are still inside! A major staff officer asked in amazement.

"Hmph, what's the use? Didn't you hear that they were ambushed by heavy fire? Even if a few survive, what role can it make? Let them collectively sacrifice their lives for the country! Zhang Youzhao's old face sank, snorted coldly in displeasure, and said coldly: "Immediately carry out the order, major!" ”

"Yes, Commander!" The major's heart trembled, and he turned around helplessly, mechanically conveying Zhang Youzhao's somewhat ruthless order.

"Haoyi, Haoyi, it seems that you have a way to heaven, and you want to break into hell!" Looking at those holographic images turning into snowflake images representing the loss of signal in groups, Zhang Youzhao's old eyes slowly narrowed into a thin slit, and the cold light flashed and whispered to himself coldly.

"Bang!" In the corridor of a certain floor of the abandoned factory, Hao Yi, who had changed into a single soldier light armor, raised the rifle in his hand, and pulled the trigger heavily on the head of a Marine lying on the ground wailing and moaning. An armor-piercing spike tore through the seriously wounded man's helmet in an instant, and a cloud of red and white blood splattered out.

"I said, why don't you even spare the wounded?" Liu Kai, who was also carrying a rifle, walked over with a relaxed face and said with a smile to Haoyi.

"Do you still want to save him?" Haoyi turned his head, glared at Liu Kai angrily, and said in a cold tone: "That's not the style of you cold-blooded agents!" Besides, he hurt his chest to the core, and even if I hadn't given him a ride, by the time his comrades came to save him, I'm afraid he would have turned into a dead corpse! They are all warriors, so it's better to let him go a little more happily than this! ”

"Yo, it seems that you are not as cold-blooded as the legend says!" Liu Kai kicked the Marine who had turned into a dead corpse at his feet, raised his face and said teasingly.

"Alright, don't put this nonsense aside, hurry up and clean up! This is just the first wave of the opponent's tentative attack, and the next wave is estimated to be not so easy! Hao Yi replied coldly, not as if he didn't care about the faint ridicule in Liu Kai's words.

"Huh......" However, just as Haoyi turned around to leave, there was a sudden sound of breaking the air in the air.

"Lie down!" Hao Yi, who has been on the battlefield for a long time, is naturally very familiar with this kind of sound of breaking the air. It was a sound unique to the firing of siege tanks' high-powered plasma guns. Suddenly, Haoyi's face changed drastically, and he hurriedly turned around and shouted to the agents who were busy checking if there was any life.

"Boom, boom!" Before Haoyi could finish speaking, huge fireballs rose up in the factory one after another. The earth seemed to tremble faintly with a loud roar like rolling thunder. The entire factory seemed to be blown away, and the buildings were crumbling in the midst of a ball of fire.

"Bang bang bang!" Before the rain of plasma artillery of the siege tanks was over, a cloud of blackened Punisher grenades swept in and fell on the ruined factory that was about to collapse.

Almost instantly, the entire factory was engulfed in a cloud of bright fireballs and billowing smoke. The originally bright canopy of heaven seemed to have dimmed suddenly, and only the continuous, deafening, and thunderous roar between heaven and earth remained......
