"Kill!" The position has become a mess, the accumulation of a large number of corpses has made it difficult for the Zerg to charge, and the remaining human warriors are still relying on the terrain advantage in various trenches to make the last resistance to the Zerg. The humans and zergs who had slaughtered all of them were fighting by instinct, with no tactics, no skills, only wild roars.

"Kill!" A bayonet nailed a large dog into the trench, and before Mark could draw his gun and retreat, another large dog had already pounced on him from the side and threw Mark into the trench. "Drink!" The moment he fell into the trench, Mark rolled with the big dog in his arms, and successfully swapped positions with the big dog. "Die!" Holding the dog firmly under him, Mark drew his saber and stabbed it in the mouth the moment the dog opened its mouth to bite. Releasing the dog's neck, Mark rubbed the blood-soaked saber twice on the dog's body and thrust the saber back into the scabbard at his waist.

"Damn, my gun is still outside." Looking at the mountains of corpses piled up in the trenches, Mark couldn't help frowning, and said in his heart, how many people are still alive? When he got up, he wanted to go outside the trench to get his AGH12 back, and when his head was just out of the trench, Mark saw a dazzling pillar of light rising into the sky, and subconsciously blocked it with his hand. However, he quickly put down his hand, and the observation system automatically switched to the bright light horizon for him, and he could look directly at such a bright light.

"Boom———— When the pillar of light rose to a critical point, a loud bang swept the earth along with waves of fire and shockwaves. "Attention combatants, a nuclear explosion has occurred in the nearby area and the radiation is spreading, please evacuate immediately! Repeating ........." "Nuclear bomb ........." Mark couldn't help but swallow his saliva, within the field of vision of the human warriors, the millions of Zerg who launched the group charge, only the vicinity of the human defense line had not been affected by the nuclear bomb, and in the valley, there was already a sea of fire, and a huge mushroom cloud rose from the Great Rift Valley.

Sitting in the trench, Mark had no intention of leaving the trench, the shock wave and the high temperature were still raging outside, even the huge thunder beast was thrown into the sky by the shock wave, and he was probably blown directly into the black storm rolling in the sky when he went out with a small number of marines, and what did he mention to get out of the radiation zone.

The entire battlefield pattern was completely disrupted by a nuclear bomb: almost half of the Zerg army was wiped out, and most of the remnants were struggling with the pain caused by radiation and basically lost their combat effectiveness; The follow-up troops of the Zerg are still outside the Great Rift Valley, and there are many large Zerg such as Thunder Beasts and Poisonous Explosion Mother Worms, but the fear of nuclear bombs makes them dare not enter the Great Rift Valley at all now, and the threat of these Zerg has been temporarily lifted; The Zerg forward is still fighting with the human troops, but the resistance of the human troops is extremely tenacious, the battle fortress is still covered by fire, and the warriors on both wings use their lives to block the pace of the Zerg rushing to the battle fortress, this battle may not be the one-sided situation before.

Inside the battle fortress, the commander-in-chief and the others, who had been nervous before, finally breathed a sigh of relief, and now it seemed that everyone finally had a chance to live. "Lao Feng, you guard the battle fortress, the command belongs, except for the communicator, all bring guns to follow me. The warriors are running out of ammunition and food, and they are still fighting the Zerg outside, so we should do something about it. "Lao Liu, don't worry, I will let them never come to the Zerg in the middle line." The Battle Fortress and the Grimm cannon will always be on the lookout for the Zerg Air Force, and the Zerg Wyvern's poop will not fall on your head. The commander-in-chief picked up the helmet on the table, put it on, turned to the staff officer and said, "I have always believed what you said you can do, if you don't do it, you will die, and the flying dragon has really never seen it." With that, the commander-in-chief took 12 soldiers from the command out of the battle fortress. This guy keeps calling to base 030, I'm staring at the mid-line battlefield, the automatic fire output has been increased to the suppression stage, now is a good time to eliminate the Zerg striker. "Yes."

"Hold this firepower support point, Tian Yong! Can your 'Ripper' still move! "It's very difficult, my right leg and right arm are all damaged by the Venom Monster, I need to use the machine gun with my left arm, I can't walk away with my left leg alone." "Our ammo won't last long, or shall we get you out of it?" "Don't, I don't want to die yet, my space suit has long been torn, otherwise I'll go back here, and now I'll be dead when I go out!" "Captain! The Zerg are up again! "Damn it, hold the trenches! Tian Yong, you cover us. Saying that, the captain picked up the AGH12, which had only three bullets, and rushed out, and in this nearly two-meter-and-a-half deep machine gun fortress, only the badly damaged "Ripper" leaned against the wall and fired outwards with great difficulty.

"Boom-" A Marine suddenly "flew" in from the entrance, slamming into the wall with a muffled thud. "What's going on?" Looking at the marines who were suddenly thrown in, Tian Yong was stunned. "Isn't this Captain Wang? What's wrong with you? The captain said with great difficulty, "Run" and "Roar-" A venom monster roared and rushed in, squirting a mouthful of corrosive acid at Tian Yong's unsuspecting "Ripper", and the inevitable "Ripper" pointed the machine gun at the Venom monster with the corrosive liquid. "Bye bye ......" "Bang bang-" Tian Yong pulled the trigger and shot out the shells in the magazine in one go, and the venom monster was beaten into a pile of rotten meat and piled up by the wall. "Boom-" The corrosive liquid slowly corroded the neck armor of the "Ripper", and Tian Yong released the linker in despair.

"Roar-roar-" There were a large number of stinging snake cries outside, and Tian Yong, who was already waiting for the oxygen leakage from the driver's compartment to death, suddenly laughed weirdly. "So many venom monsters......... Hehehehe......... That's enough...... Nuclear battery, interrupting energy output, forced unlocking, self-destruct program starts, fission begins. "Fission is starting to ........." "Roar-" A bunch of venom monsters roared in, and the "Ripper" used the last of his energy to turn the cannon and pull the trigger towards the entrance. "Bang bang-" "Kill! "Fission-" "Boom-" A small mushroom cloud rose from the machine gun fortress, and all the nearby zerg and humans were scorched in the nuclear explosion.........
