December 17, 2070 at 5 p.m. __Shariz Star Centipede Rift Valley__

The night of Sharitz came quietly, and the surface temperature of the day, which was as high as fifty or sixty degrees Celsius, began to drop rapidly, and soon fell below freezing. The countless huge black tornadoes in the sky were still roaring, not because of one or two explosions of thunder from the collision, if there were any flying objects flying in the sky above one hundred and fifty meters at this time, they would definitely be torn to pieces, which is why the Zerg did not send an air force to attack the human troops.

"Thermal harmonic starts." The fully sealed combat armor can protect the human body from the cold, but some of the joints of the armor itself are exposed to the air, and the low temperature starting at minus 80C will affect the armor, so the thermal energy harmonizer to maintain the temperature of the joints is constant. The thermal energy modulator, as the name suggests, is an instrument that can adjust the temperature synchronously, and in layman's terms, it is the space version of the super air conditioner. The strong and stable energy output of the high-energy particle battery allows the harmonic to withstand the harsh space environment from up to 800C and down to minus 350C, which is really a must-have for Marines to travel at home and fight against the Zerg.

"We are now in the middle of the rift valley, 17 kilometres from the exit to the north. Judging by the dense gunfire before, the large force should be in this position. As he spoke, Mark pointed to the map, where a small green dot was marked on the location of a fork in the valley. Seeing that everyone was staring intently at the map, Mark continued: "The interference of brain worms has made us lose the ability to communicate over long distances, and our individual radio only has a communication range of three kilometers, and the safest way to contact the 3 main forces is to go here, on this mountain. It's a vantage point, and when we get there, we can see the whole Northern Rift Valley, and we can safely connect with the main force, so we'll go here early tomorrow morning. Pets are active at night and hope we can hide here safely. "Mark, this cave is so deep, there won't be zergs in it, right?" Looking at the inside of the unfathomable cave, Mark was also faintly worried, judging from the traces on the ground, there were indeed zerg haunts here.

"It can only depend on our luck, I hope the Zerg are all out now." "Mark, it's not safe here, let's ......" El obviously also judged the traces of the Zerg passing on the ground, and was very worried, even the insurance of AGH12 was opened. Da -" "Bang Bang "Boom-"Ah--help-ah-" "Squeak-" "Whew-" "Withdraw!" "The sound of explosions, gunshots, the screams of humans before they died, the screams of the Zerg, pierced the silence of the rift, and the whole rift reverberated with war.

Taking a deep breath, Mark suppressed the fear in his heart and said to everyone: "Go out now, there is really only one dead end, how far can our night vision devices see?" 500 meters is the limit. The thermal imager is good, you can see clearly, but what do you see after the Zerg dig into the ground? You have no idea where they're going to come from. Turn on the searchlight? Let's look for death. Fighting at night wasn't what we're good at, let alone now that the sky is obscured by a dark storm. So we'd better stay here and act when it's dawn. "It takes six hours for Shariz to rotate around the planet, so how do we make it until dawn?" Are you playing dead here?! Faced with the Zerg that could appear at any time, Stephen, who had been silent before, questioned. After all, humans are not zergs, and they still have thoughts and feelings such as fear, and when their own lives are threatened, fear spreads.

The six people present were all on the battlefield for the first time, and although they had been trained, their mental endurance was not enough to face this situation, and even Mark, who seemed to be calm, had doubts about his decision. When questioned, the anger in Mark's heart was also aroused, and he asked sharply: "Then do you have a better way?" Shouldn't we rush out? Go and die?! "It's better than waiting to die here!" "Then you go!" "Boom-" Just as the two were arguing, a cloud of fire rose into the sky in the rift, and the loud explosion echoed throughout the rift. Calm down the startled Stephen asked. "What's that?" Mark sighed and turned to walk back into the cave. "That's the 'ripper' who blew himself up." The crowd was silent.

"Whew-" "Squeak-" A large number of zerg cries suddenly came from outside the cave, and the five Stephens were all stunned, and then looked at Mark in horror. With a punch on the cave wall, Mark turned to scan the crowd and jerked the bolt. "Two ways, fight to the death with the Zerg here, or escape inside. I'll go inside, what about you? With that, Mark ran into the cave without looking back. Without saying a word, Watts picked up his gun and followed. James and El looked at each other, nodded at the same time, and followed, leaving Stephen and Carl staring at each other.

Looking outside the cave, Karl, who rarely spoke, spoke. "Let's keep up, Zerg, it's getting closer." "Carl, you ......" "It's hard for us to survive without them, and I don't want to go out and die now, let's go." With that, Carl patted Stephen on the shoulder and ran into the cave. "I'll do it!" With a snort, Stephen reluctantly followed.........

17:40 __Centipede Rift Valley__Where is the main force of the human forces__"Dada-" "Bang Bang Bang-" "The 14th squad fills the gap!" 'Ripper' Attack! "Boom-" In a narrow valley, the Zerg rolled up the waves of flesh and blood again and again and kept hitting the steel defense line built by the human troops, and the corpses of the Zerg had built countless corpse mountains at the mouth of the valley, but they still launched a suicidal charge without knowing what fear was, and there was no sign of stopping.

"Ahh Ahh "Boom-" The moment the team's signal disappeared from the bioprobe, the Zerg piled up there were suddenly blown up into the sky. "Kill!" The death of the teammate drove the rest of the team into a frenzy, and almost instantly, dozens of kilograms of explosives were thrown into the insect tide. "Boom-" The hard limestone ground of the Great Rift Valley was blasted into a large crater with a diameter of twenty meters, and none of the Zerg in it were spared. The "Ripper" fired two incendiary bombs into the crater, and the raging fire temporarily stopped the insect tide.

Before the warriors could breathe a sigh of relief, more Zerg poured into the fire pit desperately, as if they wanted to fill a path of attack with their lives. Everyone was stunned, but they didn't stop attacking, and the intertwined network of fire continued to harvest the lives of the zerg. The squad leader in charge of the command observed for a while, gritted his teeth, and gave the order. "It's not going to work like this, we're running out of ammunition! All of them! Fall back! Retreat to the second line of defense! Throw me all the incendiary bombs, grenades! Let's withdraw! "More than a dozen marines who blocked the Zerg at the mouth of this fork in the valley threw a round of grenades in unison, and then spread their feet and ran." The Ripper "retreated and covered the others, and at the same time, incendiary bombs and high-explosive grenades poured out at a rapid pace. At this moment, a sudden change occurred.

"Boom-boom-" "Roar-" In the cracking and collapsing sound of the mountain rocks, a huge zerg suddenly broke out of the mountain. "Knock-" In the frightened eyes of the human warriors, the huge fangs up to 9 meters long waved hard, and the "Ripper", which was more than 3 meters high and weighed two tons, was swept directly into the mountain wall on the side, and almost returned to the state of parts in the violent collision, and the pilot was squeezed to death by the deformed cabin at the moment when the "Tearer" was swept away. Before the rest of the team could recover from the shock, the second swing of the giant zerg had arrived. "Boom-" In the deafening loud noise, except for a few members of the team who reacted quickly and immediately fell to the ground to avoid a catastrophe, the rest of the team members all became puddles of flesh and mud.

"Run!" One of the quickest reflexes gets up from the ground and runs, heading straight for the second line of defense. The rest of the team members also fled desperately, and they couldn't even care about the weapons that fell to the ground, and they simply lost their armor. The giant zerg did not pursue, and in its eyes, these weak creatures were not worth its attack. The Zerg, who had been blocked by the fire pit for a long time, also successfully rushed over at this time, and attacked the second line of defense together with the giant Zerg.

The same scene played out at the mouth of multiple forks and valleys, and the sudden appearance of the giant Zerg caught the human troops by surprise, and for a while, the human troops suffered heavy casualties.

Headquarters......

"Commander-in-chief, we have too little heavy equipment in our hands, and we can't stop the giant Zerg at all!" "The casualties have exceeded two hundred, commander-in-chief, we can't fight like this!" The commander-in-chief is now also a head or two, and this thunder beast appeared too suddenly. "Everyone, the thunder beast is indeed difficult to deal with, but we are not yet at the point where we have nothing to do." Opening the 3D projection map, Commander Liu pointed to the fork valley where the main force was located, and said: "Our current position is here, this is the end of this fork valley, we have no way to retreat, our only chance is at the fork at the junction of many forks and valleys." The Zerg forces will definitely assemble here before launching a general attack, and instead of letting the troops be consumed in various valleys, we should concentrate all our forces here and fight the Zerg to the death. We can plant mines here, ** in advance, and place 'Rippers', automatic cannons, and ordinary soldiers on the mountain walls on both sides to form a crossfire network, so that all the Zerg can be buried at the fork! "That's the best thing to do so far, so let's do it." "Let's go and arrange it right away!" The whole army immediately got busy.........

At the same time, after a long journey, Mark and his party had crossed a long and narrow road, and the road ahead began to widen, and a little light could be faintly seen. "There is light! Quick, let's get over there! Everyone seemed to see hope, and the speed under their feet was a little faster. Mark was the first to rush out of the corridor, and then he stayed there. "Oh my God......"
