When Tang Moqi's car drove over, the explosion finally calmed down, and the entire research institute was completely in ruins, accompanied by the screams of people in the firelight, it was simply a hell on earth.

Tang Moqi took two deep breaths before suppressing his urge to rush in, and the soldiers surrounded the explosion area to extinguish the fire, using fire seedlings to spread to other areas to cause even bigger fires. As for the center of the explosion, due to the lack of fire extinguishing equipment, no one tried to extinguish the fire at all, only to wait for it to burn out and extinguish itself.

Tang Moqi found fireproof materials from the space and put them on, and circled around the periphery twice under the cover of thick smoke before finding a suitable time to run into the fire. Tang Moqi had been tortured in the research institute in his previous life, and he had secretly studied the structure of the research institute, if nothing else, Tang Jianfeng should have stayed in the third basement floor of the research institute, which was also the most confidential layer of the research institute.

Tang Moqi tried his best to walk in an area without open flames, but after only five minutes, he couldn't stand it, the heat had already burned the soles of his feet into blisters, and Tang Moqi dodged into the space. After taking off the equipment, he didn't care about the burns on his feet, so he changed his set and continued to go out.

Fortunately, the hidden passage leading to the underground was blown open, and Tang Moqi easily found the stairs down. There was a lack of oxygen in the underground structure, and the open flames had been extinguished by this time, but visibility under the smoke was barely more than two meters. Tang Moqi flashed his flashlight forward, and occasionally he could see one or two researchers in white coats lying on the ground, not knowing whether they were unconscious or dead.

The security of the entire research institute was very tight, and Tang Moqi turned around for a long time before he found the passage to the second basement floor. The second basement floor is much more advanced than the top, but the doors of each research room have been deformed by the blast wave, and occasionally you can see various zombies locked in chains, as well as corpses soaked in huge transparent jars.

In the last life, before Tang Moqi was arrested and brought to the research institute, the research institute had long been known to the public, but what the research institute was studying and who was manipulating it had never really been made public. It wasn't until Tang Moqi himself experienced it that he knew that this institute was simply dressed in the cloak of all mankind, and it was all an unsightly biochemical reality in private.

The timing of this explosion really couldn't help but make him think about it, especially under the premise that Tang Jianfeng's ability was still a fire-based ability, Tang Moqi's whole person was tense, he really didn't dare to imagine what he would do if something happened to Tang Jianfeng.

When Ye Jin led everyone to the southern city wall, he had already heard the sound of gunshots, and the soldiers on the city wall were obviously already shooting at the approaching zombies. Ye Jin opened the two wooden boxes left by Tang Moqi, one box contained guns and bullets, and the other box was full of them

Hand grenade!

Only Xu Shiqing and himself were familiar with firearms, although Tang Qingshu worked in the army after the arrival of the last days, he was not a real soldier and had not touched a gun.

Time was urgent, Ye Jin gave them a rough introduction, and let them take the gun and bring the bullet to the field.

The southern wall is the weakest part of the entire security zone, there are neither machine guns nor tank crews, and it relies entirely on the fire of soldiers, but here the outside of the wall is very empty, there are no buildings to block the view, and it is easy to shoot and throw ammunition.

It had been nearly half an hour since the explosion began, and more and more zombies were approaching the city wall under cannon fire, and the black pressure below was either corpses or the living dead, and everyone was red-eyed and tense their nerves.

Just when the artillery fire was getting closer and closer, a "buzzing" sound gradually became clear from small to large, everyone finally came back to their senses, looked at each other, and under the panicked eyes of everyone, a red firework suddenly exploded over the west city wall.

Almost at the same time, everyone's faces turned white, which was the highest level of red flag. "Corpse tide!" Zhang Yunfei exclaimed, got up and immediately ran to the west, and everyone reacted and spread their legs and followed.

As they got closer and closer to the west, the sound of artillery fire became more and more intensive, and the "buzzing" sound became louder and louder, and everyone climbed the city wall to see, and immediately gasped, only to see that the entire west was full of roaring zombies, so dense that they could no longer see the ground, and there were zombies in the distance who continued to join the team because of the sound.

Not to mention ordinary people, even the ones who go out to deal with zombies every day are already in a cold sweat. Ye Jin stared at the cannon that made a loud noise and frowned, and said, "If you go on like this, it is tantamount to drinking to quench your thirst, and the more zombies fight, the more you will grow." ”

The command class soon discovered this problem, and the artillery attack was immediately reduced, but a large number of zombies were still crowded in this direction, and relying on the bullets of the soldiers alone was a drop in the bucket.

Ye Jin and the others joined the soldiers to shoot together. The corpses soon began to pile up under the walls, and danger loomed at every step. Just when everyone was about to despair, several helicopters suddenly flew over their heads, and the loud noise of the helicopters immediately attracted the attention of the zombies. The helicopter circled a few times and began to fly into the distance guidedly, Ye Zeyue picked up the telescope hanging on his chest and looked over, and everyone was secretly relieved to see that the zombies below finally stopped moving forward.

Zhang Zicheng also came over at this time, took Ye Zeyue's telescope and looked over, but he didn't expect to be surprised by what he saw through the glass.

Everyone only heard his frightened scream, and then saw Zhang Zicheng's pale face, Ye Jin immediately snatched the telescope in his hand and looked over, then breathed rapidly, scolded and smashed his fist into the low wall of the city wall in front of him.

The helicopter hovered very low, everyone couldn't see what was happening, they all eagerly took the binoculars, Ye Jin stopped Ye Zeyue from taking the binoculars, looked at everyone, and said with a heavy face: "They are throwing living people down!"

Everyone gasped and stared at each other in shock. The zombies in the distance really became excited, and began to move with the helicopter, and more zombies joined the chasing team, and the pressure on the city wall was immediately greatly reduced.

The uninformed people cheered in the joy of the rest of their lives after the catastrophe, and Ye Jin and the others who saw the insiders all looked at the retreating corpse tide with a sinking face, only to feel that a gloomy and painful atmosphere lingered around them, burning everyone's souls.

At this time, the sound of artillery fire in the safety zone finally stopped, the smell of gunpowder smoke continued to permeate, and the panicked survivors finally cried, however, the sky that had been gloomy for a day suddenly cleared, and even a rare sunset appeared.
