"Da Da-" "Bang Bang Bang-" "Bang-Bang-" Marines, Snipers, "Rippers", Grimm Machine Guns, and the Battlefortress Batteries, all the firepower of the human forces is already at full capacity, but it can only slow down the pace of the Zerg's approach. "Sniper! Kill that poisonous explosive bug! Fast! "Fire with all your might!" Don't save ammo! That's what you think about when you have a life to live! Fire! Fire! "Rocket artillery, laser cannons, give me the thunder beast that beats it! They must not be allowed to rush over! The commanders shouted orders at the top of their voices, and the weapons in their hands roared together, as did the soldiers around them, each of whom was on the verge of madness under the threat of death. In the face of the Zerg thousands of times larger than yourself, if you can still remain calm, you will be a true god. However, it seems that there are such people.........

"Bang———— bang———— bang————" Lao Liu used armor-piercing bullets to shoot unhurriedly, and each shot could basically take away a zerg. "Whoosh-" Lao Liu, who heard the sound of breaking the air, subconsciously squatted back into the trench, and then, "Bell-bell-" A piece of cone bullets struck, and all the cone bullets hit the outer wall of the trench and penetrated into the steel plate, but no one was hit, it was really a false alarm. Revealing the top of his head, Lao Liu took a look at the situation outside with the help of the observation system. "Well, there is at least one hundred and seventy meters to go, and you can continue to fight." "Captain! There's a thunder beast coming at us! Hearing Zuo Teng's shouting, Lao Liu was stunned for a moment and asked, "Didn't the command let the rocket artillery and laser cannon squads attack?" "I just called for shelling, and they said there were no more shells!" Lao Liu was silent, shook his head and took out a total of ten grenades that he got through the back door. Looking at the thunder beast that was still nearly four hundred meters away, Lao Liu said in a deep voice, "Everyone, throw a round of grenades, retreat the Zerg*, and cover me to attack the thunder beast!" "Yes!"

"Boom-boom-" In the violent explosion, Lao Liu's zerg in this section of the defense line was cleared. Without the interference of other zergs, Lao Liu jumped to the trench at once, and it was a grenade against the thunder beast in the distance. "Boom-" "Boom-" The grenade deviated slightly from the target and exploded at the shoulder of the thunder beast, and the thunder beast that was hurt by the explosion picked up its back shell and rushed over at an accelerated speed. "Boom-" "Boom-" Another grenade, this time hit the back shell of the thunderbeast, causing no damage. Lao Liu stopped, and after visual inspection again and proofreading with the assistance of the observation system, he fired three grenades in a row. "Uh-huh-huh-"

"Boom-boom-boom-" "Boom-" Two of the three grenades hit the thunderbeast's head, which really hurt it, and it shook its huge bloody head and roared, and then knelt heavily on the ground...... "Good fight!" "Pretty!" "Captain mighty!" The soldiers on the defense line all applauded Lao Liu Lu's hand, after all, it was rare for a thunder beast to be injured by a marine. "The Zerg are coming up again!" "Go back to the trenches, and keep fighting!" For the time being, no one paid attention to the injured thunder beast, and the firepower was once again concentrated on the Zerg attacking on the ground.

The Zerg seemed to be deliberately conserving their air power, and after the first round of air attacks were killed by the Grimm machine guns and the battle fortress anti-aircraft fire network, there were no more Zerg air forces charging in groups, only sporadic Wyverns interspersed with harassing attacks, bringing a small number of casualties. In the face of such a fighting style of the Zerg, the commander-in-chief felt a little uneasy, but he couldn't say why, so he could only let the Green machine gun not attack the Zerg on the ground and be on call at any time.

"Captain, that thunderbeast is moving again!" Old Liu Wenyan, who was sitting in the trench to replace the magazine, sat up all of a sudden, and looked at the thunder beast that came over with a shake, and his facial muscles couldn't help twitching. "Why is this thunder beast so beaten!? All set on fire and kill it! "Captain, I'm out of bullets!" "Me too!" The team members all looked at Lao Liu in a daze, waiting for him to pay attention, and in just over ten seconds, most of the positions were dumbfounded, and the Zerg took the opportunity to launch a jumping charge, which was less than 50 meters away from the humble earth city.

"Boom-boom-boom-" Lao Liu used all the grenades in one go, and in the dazzling firelight, the injured thunderbeast fell along with the other zergs in its vicinity. "I also have five regular magazines here, a total of 200 rounds, 10 rounds per person, to be used when necessary. Guys, are you ready to fight bayonets?! "Kill!" "Let them come!" "Woo-" "Oooo ”

The Zerg were near, close, close, they rushed under the earthen wall, and most of the warriors had no bullets, and basically could only watch them scratch and bite the earthen wall. "Stand back! Retreat to the mountain! "The commander-in-chief also knew the difficulties of the warriors, and gave the order to retreat, this earthen wall was originally just to block the Zerg for a moment, he didn't expect the soil to be able to hold the Zerg who were good at making holes." Remove! Remove! 'Ripper' machine gun cover. "The warriors withdrew from the earthen wall, and under the rapid grasp and bite of the zerg, many gaps soon appeared in the earthen wall, and countless zergs poured over from the gaps." Bang bang - "Dozens of "Ripper" fired with all their might, trying to block the Zerg back, but there were too many gaps, and the Zerg quickly rushed through the fire blockade of the "Ripper" and went straight to the foot of the mountain. "Commander-in-Chief!" "The Battle Fortress is firing in full force! Sweep the Zerg in the middle line, and the two wings will only depend on the warriors themselves. "Yes!"

———The 18.5mm "Fire Flash" Launch/Close-in Gun and the 12.5mm Thunderbolt Close-———— Gunner attacked together with the "Bang " Battle Fortress, and the Zerg in the middle of the battle line were swept away. But on both wings, more than 800 human warriors will have to fight against the Zerg who are thousands of times their size, and the pressure is unprecedented. "Kill!" Shouting, Mark took the AGH12 and rushed to the swarm first, and his teammates followed, and the fierce hand-to-hand combat began.

"Huh-" Without any fancy front stabs, Mark directly pierced the head of one of the fastest rushing dogs, and there was no time to make other moves, and the Zerg on both sides had already rushed up. "Snort-sss "you!" Kicking back a large dog that rushed up, Mark didn't have time to think about it, and pulled the trigger on the stinging snake in the distance. "Da-" "Whoosh-" The stinging snake and a human warrior fell to the ground at the same time, Mark was still half a step late, and the spinal spur bullet of the stinging snake pierced the warrior's visor. "Damn the stinging snake! Beware of the spinal cord stinging bullets of the snake! "The battle is getting more and more intense.........
