December 17, 2070 23:20 __ Shariz Star Centipede Rift Valley __ 280 meters deep in the underground passage __

Mark and the two ran wildly all the way, and finally approached the source of the explosion, and as long as they turned another corner, they could see the extremely long passage where Lao Liu and the others were fighting. "It's just ahead, Mark, let's hurry up!" "El, stop!" El was puzzled, but out of trust in Mark, he stopped. "What's wrong?" Mark stood still, as if he was not sure, and leaned on the ground to listen carefully with the help of an external sound picker. "Oh my God, this amount......... El, the great army of the Zerg is ahead...... We can't get by........." El was silent, threw away the AGH12 in his hand, retreated to the wall, and sat down slowly with his back against the wall. "We're on the road......... Mark was silent, but his fists were still clenched.

"No, El, we still have a way." "There is a way? There are pursuers in front and interceptions in the back, where is our road? "El, the road has always been there, but you don't see it. A great man of our nation once said that there is no road in the world, but when many people walk, it becomes a road. "You mean...... Mark stretched out his right hand to El, who was sitting on the ground, and said extremely firmly: "We are warriors, and the road is the bloody road we killed!" El was stunned, the current Mark was completely different from usual, sharp, and he could even feel the murderous aura on Mark's body. "El." "I'll do it! I haven't done anything crazy in my life, so I'm going to go crazy with you bastard this time! "Haha, I knew you kid had a kind! Take your weapons, if Lao Liu or the instructor sees you doing this, you will be sent to the giant tiger cage for a month! "you, let's go?" "Waiting, must you?" Grabbing Mark's outstretched right hand, El sat up from the floor and picked up AGH12. "Why, you humans, are also going to charge."

Extra-long underpass ......

"Squeak-" "Squeak-" "Whew-" A large number of zergs roared through and rushed towards the battlefield outside the cave. "Wow-" "Go-" "Boom-" Suddenly, a fireball rose up in the underground passage, and with a loud bang, Mark and El came out of a small cave. "Kill!" "Da-da-" Desperately pulling the trigger of the AGH12, Mark jumped into the clearing where the last grenade blew up. In front of Mark's eyes, one after another Zerg was beaten by ag12 and their flesh and blood were blurred, and their beast-like intelligence made them unable to find the north for a while, which Zerg would have thought that there would be humans attacking in such a safe place? "Wow!" El then jumped down and fired a grenade in mid-air in the direction where the Zerg came from, and the grenade flew hundreds of meters and fell into the swarm, setting off a rain of flesh and blood. "Click-bang-bang-" Draining the normal magazine and switching directly to armor-piercing shells, Mark launched a charge in the direction of the previous explosion. "Let's rush forward!" "Good!"

The road ahead was clogged with the Zerg, and the high-energy particle battery of Mark and El's battle armor was running at full capacity, and the two opened the electromagnetic catapult on the soles of their feet and bounced towards it at an alarming speed. "Huh-" A big dog jumped up and pounced on Eyre, who had nowhere to borrow strength in the air, but unexpectedly, El stepped on the big dog's face, and the powerful electromagnetic energy pressed the big dog back to the ground, and made El continue to leap forward for a distance. "Huh-" "Huh-" The moment he landed, Mark used the AGH12 in his hand as a big knife and slashed at the head of a stinging snake, and in an instant, the snake body and the snake head were separated. "Bang bang bang-" fired several shots, and the surrounding zerg were all killed by Mark, and El also fell at this time. It took more than ten seconds for the electromagnetic catapult to be charged, and the two of them ran forward wildly, and the zerg who blocked them couldn't stop it at all, and they suffered heavy casualties.

"El, another grenade!" Hearing Mark's words, El turned around and fired another grenade, and the pursuing Zerg behind him was divided into three sections. "Jump!" "Jump!" The electromagnetic catapult was recharged, and Mark and the two jumped out again. In mid-air, the two of them quickly replaced the magazine, and completed the replacement before landing. "Mark be careful!" El's reminder was half a step late, and a hundred meters away, more than a dozen stinging snakes sprayed a large number of spinal cord spur bullets at the moment Mark landed, and Mark, who had just landed, had nowhere to dodge and was hit by a large number of cone spur bullets. "Mark! Zerg! your grandma! "Uhh Just when El was grieving, Mark, who had been pierced into a hedgehog, suddenly moved, and pulled out the cone bullets that were pierced in his body one by one.

El was stunned, he was hit by so many cone-stabbing bullets, it stands to reason that Mark should have died a long time ago, but he didn't expect to ......... "El, get down." "Huh? Belch. "Boom-" "Boom-" A grenade was fired at the Zerg who were close in front of him, and the explosion affected all the Zerg within a radius of 30 meters, as well as Mark and El. "Mark?" "Huh-" "Boom-" The Zerg who were chasing behind were also shot, and hundreds of Zerg didn't even know how they died. In the smoke of gunfire, Mark dragged El, who had fallen to the ground. "Let's go." "Hmm." El saw Mark's strange appearance now, but Mark had saved himself, and out of trust in his brother, El didn't ask much. The electromagnetic catapult had been recharged, and Mark and El had bounced out again, and the extra-long underground passage had already been more than half of them.

Outside the cave, the clearing troops sent by the main force have all withdrawn from the cave and regrouped. Lao Liu, they found a large number of Zerg, and so did the other teams, this is not something they can deal with, they should retreat. Just as the clearance troops were about to return, the sound of intense firefights and explosions was heard from inside the cave. "Are there any troops in there?" The captains of each squad checked the number of their troops, and there was no shortage of people in the team. "That'...... That could be Mark them! Ivan couldn't help but say his opinion, Lao Liu and the others were shocked, Zuo Teng rushed into the cave with a good bayonet, and was pulled back by Lao Liu. Captain! "I know, I didn't say no. All of them, go into the cave and rescue our teammates! Come on! "Rush!" Under the shocked gaze of the other squad fighters, Mark and all the members of his squad rushed into the cave with a shout.

"Bang However, this place is blocked in the air by a large number of venom monsters, and the bouncing is absolutely finished, so you can only rush the big dog pile head-on. "El, let's go!" "Kill!" There was little ammunition left, and Mark and the others chose hand-to-hand combat, first, to save ammunition, and second, to avoid the Venom monster's attack through the big dog, and the last grenade on Mark's body was reserved for those Venom monsters. Holding a saber in his left hand and an AGH12 with a bayonet in his right hand, he turned the output power of the high-energy particle battery to the maximum, and Mark rushed into the big dog pack and slashed and stabbed, turning a blind eye to the big dog's bite and carrying it hard with his armor. El followed, and agh12 became a machete in his hand, directly slashing at the gun. Although the two of them have maintained the momentum of rushing forward, the armor on their bodies is constantly damaged, and the energy of the high-energy particle battery has plummeted. "Mark, I can't hold it up like this!" "Then fire, now as long as you can get out of this passage! Don't care about anything else! "Bang bang-" "Da da da-" The big dog kept falling, and finally, the last obstacle to the underground passage, ——— Venom Monster, appeared in front of Mark and the others. "El, the last shot, rushing against the flames." "Understood." "Uh-" The flames from the explosion of the "Boom ————" swept through the passage, and Mark and El took the opportunity to activate the electromagnetic ejection and burrow through the flames, dodging the Venom Monster's covering corrosive venom.

"Knock-" "Bang-" Mark and Er, whose vision was blocked by the flames, landed unsteadily, one smashed a big dog to death, the other knocked over a stinging snake, in short, fell into the sea of zergs, and a large number of zergs looked at these two pitch-black "non-creatures" in a daze. "Your sister, Mark, why are you so close?!" "Don't talk about my sister! How can you block Venom Monster's covering attack if you don't hit so close? Well? Got in the pile of worms? I'll go! Then kill! Leaping from the ground, Mark and El pulled the trigger together. Bang-click-" "Da-click-" At this crucial moment, the two dropped their chains together, and their guns ran out of bullets. "K-" Back to back, staring at the eager Zerg around them, Mark and El were ready to fight until the last moment. "I didn't expect such a long passage to rush over, and finally confessed here, I was really unwilling." "Hehe, Er, I'm relieved to have you as a good brother with me." "Rest assured what?" "When you die, your expression is definitely uglier than mine! Hahaha! Kill! "You ugly fellow! Ha ha! Kill! ”

The Zerg pounced, and Mark and El fought back with AGH12 in hand. Mark took a step forward and stabbed three times in an instant, and all three big dogs in the air were pierced through the head by the bucket, but the fourth pounced on Mark. "Huh-" The big dog kept causing damage to Mark with its claws and spikes, but Mark didn't take a half step back, because behind him was his good brother El who was born and died with him.

"Roar—" Mark let out a beast-like roar, and the body of the gun held the big dog's paw horizontally, and the armor of his right leg charged with a blow, and kicked the big dog in the abdomen, and the big dog flew away, and its internal organs should have been shattered. But at this moment, Mark was desperate, he saw that the surrounding Zerg had all turned into stinging snakes, and through the rearview camera, Mark saw that El was still fighting with a big dog, and the situation was extremely critical. Kicking up and grabbing the corpse of a large dog on the ground, Mark rushes over and pushes El to the edge of the cave wall, but he himself carries the corpse of the big dog in front of El. At this moment, an overwhelming array of spinal cord spurs obscured El and Mark's vision. "Mark! No! ”
