"Major Xu, the direction of Beichen East Road, the eastern section of the Huizhong Road defense line, is in an emergency!"

"There are still too few people," Xu Yongping said helplessly, at this time it was a bit like tearing down the east wall to make up the west wall.

Many zombies passed by from the east side of the Bird's Nest and had come to the front of Block K of Huiyuan Apartment, less than 200 meters away from the Huizhong Road Tunnel.

"Make up 50 men in the eastern sector to maintain an even firepower across the entire line."

Xu Yongping looked at his watch, and it had been a little more than an hour since they set off.

"Hold on a little longer," Xu Yongping said to himself in his heart.

At a distance of 150 meters, the zombie horde continued to advance towards Huizhong Road, and the flames and bullets could not stop their steps. The shells of the bullets beside each soldier on the line were piled up into a small knoll, and the muzzles of the guns continued to spit out tongues of fire in front of them, and the shells flew to the sides, clanging in a string.

A bullet shaved off half of the head of a zombie in the distance, and the zombie took a few straight steps forward before falling down, being trampled on the soles of his feet by the other zombies behind him; The bodies of some zombies were torn in two by bullets, and the upper half of their bodies were still crawling tenaciously on the ground; Some zombies have lost their arms, walk a little unbalanced, and bump into the zombies next to them while shaking.

An area of several square kilometers is littered with corpses. The zombies were approaching, and the defending forces had not yet suffered casualties, but Xu Yongping knew that as the zombie herd approached further, the number of casualties would immediately appear and rise in a straight line. This result is already predestined, the only difference is that the result will come sooner or later.

At 100 meters, several firing points on the defensive line suddenly fell silent, and the fighters hurriedly changed their weapons to continue to maintain fire suppression.

"Notify everyone", Xu Yongping shouted loudly to the signal soldiers, trying to let his voice drown out the sound of gunshots: "Speed up the consumption of the remaining ammunition and prepare for withdrawal, abandon the defense line when the front of the zombie group reaches a distance of 50 meters from the defense line, and all the staff will carry out a round of bomb dropping, and immediately retreat to the second line of defense after the bomb dropping." ”

The order was conveyed, and the soldiers poured ammunition even more desperately, and for a while the march of the zombie herd was briefly suppressed.

As the distance got closer and closer, the losers finally felt the breath of the living people in front of them, and all that had attracted them before was the sound of gunfire, but now that the figures on the defensive line were already in front of them, the bloodthirsty beasts began to roar, and they quickened their pace, running and sprinting towards the Huizhong Road defense line.

The sudden acceleration of the corpses caught everyone on the line off guard, and some began to forget to continue pulling the trigger.

The distance of 50 meters was fast approaching, and the soldiers on the defensive line began to drop bombs and retreat.

Hundreds of grenades were thrown at the corpses, and a few seconds later they burst out on the front line of the corpses. The fighters began to withdraw from the line with their weapons in their arms, and all other baggage was abandoned.

The damage of the grenade to the zombie group was relatively limited, and some zombies rushed through the smoke and came to the side of the Huizhong Road tunnel, which was five or six meters high, and the wall blocked the zombies from the outside. There were several openings in the outer wall of the tunnel, and some zombies poured into them.

More and more zombies came under the wall, the zombies that arrived first were crushed underneath, and the zombies who came behind stepped on the bodies of the zombies below to climb to the top of the tunnel. The "human wall" was stacked, and the zombies who climbed to the top of the tunnel crossed the defensive line set up here and chased after the retreating soldiers.

The retreating formation began to become messy, and the soldiers who were left behind spontaneously turned around and began to shoot at the zombies chasing after them. Their firepower succeeded in suppressing and attracting the first zombies to cross the line. More and more zombies rushed up, and the warriors who were covering the retreat of their companions were gradually drowned in the tide of corpses.

"Prepare to detonate the Gao Bao explosives in the tunnel," Xu Yongping ordered during the retreat.

The entire front of the zombie group has passed through the tunnel defense line, this time detonation is the most suitable time, in addition to maximizing the damage to the zombies, you can also use the tunnel after the explosion to separate the zombie group, so that the number of corpses close to the second line of defense in the first batch will not be very large, the defense pressure is not very large, and the retreating warriors can have time to rest and re-enter the battle.

One by one, the warriors covering behind were killed and eaten by the zombies who caught up, and their sacrifices saved the lives of more of their companions. During the retreat, a total of more than 100 soldiers died on the road, and these were the elites of Huaguo.

Xu Yongping's heart ached for a while, and he could name almost every one of the soldiers he brought over. Now he had brought them here, but he could not bring them back.

On the Huizhong Road tunnel, a fire dragon rose into the air along the first line of the tunnel, and a huge explosion accompanied by vibrations came to the second line of defense, and the sound waves and tremors crossed the National Convention Center and reached the Yenching Genomics Institute of the Chinese Academy of Sciences. No one thinks it's an earthquake, everyone is speculating about what's going on ahead.

In the conference room, the cigarette in his hand had burned out, and the cigarette butt was still in Shao Yifu's hand.

"Report to the general, General Ge Congxian's helicopter brigade has arrived and is awaiting further instructions." The correspondent outside the door reported loudly.

Shao Yifu threw the cigarette butt he had been holding in his hand for a long time into the ashtray, got up and walked out of the door of the conference room.

The Huizhong Road tunnel was completely blown up by Gao Bao explosives, leaving only a 2,000-meter-long pit on both sides of the original tunnel, with burning corpses on both sides. In the northern part of the deep pit, the zombies who crossed the tunnel were knocked to the ground by the shock wave of the explosion, and at this time, they all got up and followed the zombies in front of them to continue to pursue the retreating warriors.

In the southern part of the pit, the huge group of corpses continued to advance slowly, and the zombies at the forefront reached the edge of the pit. They stopped, only to be squeezed into the pit by the steady stream of zombies behind them. More and more zombies are being squeezed into the pit, and if someone looks at the ground from high in the air at this moment, they may be frightened by this scene, and the zombie swarm spreads over the entire area like marching ants.

The Tsinghua Concord Department continued to be busy, Ge Congxian's helicopter unit had arrived and landed in the Olympic Village Science and Technology Park of the Chinese Academy of Sciences, and Qin Yi and other scientific researchers began to be arranged to board the plane. Most of the scientific research equipment was placed in the second batch of evacuation, and by this time most of it had been disassembled and packed and placed in the open space.

Qin Yi boarded the helicopter and looked at the second floor of the Genetic Research Institute. General Shao was not on the list of retreats he had arranged, and Qin Yi knew that he was still in the institute.

Qin Yi shook his head, his expression was very silent, and his short pale hair was slightly sluggish in the wind brought by the helicopter propeller.

By the window on the second floor of the research institute, Shao Yifu and Ge Congxian were standing there looking out the window at the plane preparing to take off.

This batch can finally transfer all the scientific researchers, and Shao Yifu's task is almost completed. Depending on the time remaining, the helicopter brigade will also have a chance to return, when the remaining scientific equipment will be put together with the operation.

"What about the soldiers," Ge asked first.

"I'll take them to try to transfer from the ground," Shao Yifu said with a solemn expression.

"You're not coming with us?" Ge Cong was a little surprised at first.

"Helicopter capacity is limited, so we need to load as much important equipment and documents as possible," Shao Yifu said, "The soldiers are still fighting desperately on the front line, but I, as their commander-in-chief, left first, what is it?" ”

"I will hold out with my soldiers to the end," Shao Yifu said, "and if possible, I will take them all out." ”
