Endless Journey Through Dimension

The distance of 50 meters was approaching in an instant, and the soldiers on the defense line began to drop bombs and retreat.

Hundreds of grenades were thrown towards the corpses, and a few seconds later they exploded at the front of the corpses.The soldiers carried their weapons and began to withdraw from the line of defense, and all other supplies were abandoned.

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

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

The retreating formation became messy, and the soldiers who fell behind spontaneously turned around and started shooting at the chasing zombies.Their firepower successfully suppressed and attracted the first batch of zombies who crossed the line of defense.More and more zombies rushed up, and the soldiers covering the retreat of their companions were gradually submerged in the tide of corpses.

"Prepare to detonate the high-explosive 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 is the most suitable time to detonate. In addition to bringing maximum damage to the zombies, the tunnel after the explosion can also be used to separate the zombie group, so that the first batch The number of corpses close to the second line of defense will not be large, and the defensive pressure is not too great. The retreated soldiers can have time to rest and rejoin the battle.

The soldiers covering behind were killed and eaten one by one by the chasing zombies, and their sacrifices saved the lives of more companions.

During the retreat, a total of more than 100 fighters and four supernatural beings died on the road. These are the elites of their own troops.

Xu Yongping's heart ached for a while. He could name almost every one of these soldiers brought over.Now he brought them here, but he couldn't bring them back.

On the Huizhong Road Tunnel, a fire dragon soared into the sky along the tunnel line. The huge explosion accompanied by vibrations came to the second line of defense. The sound waves and vibrations passed the National Convention Center and reached the Yanjing Genomics Institute of the Chinese Academy of Sciences and the Tsinghua Concorde Department. Everyone felt the shock wave this time.No one thought it was an earthquake, and everyone was guessing what was happening ahead.

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

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

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

The Huizhong Road Tunnel was completely blown up by high-explosive explosives, leaving only a 2000-meter-long pit at the site of the original tunnel, with burning corpses on both sides of the pit.In the northern part of the pit, the zombies who crossed the tunnel were knocked to the ground by the shock wave of the explosion. At this time, they got up one after another, followed the zombies in front and continued to pursue the retreating soldiers.

In the south of the deep pit, the huge group of corpses continued to move forward slowly, and the most advanced zombies reached the edge of the deep pit.They stopped, but were pushed into the deep pit by the continuous stream of zombies behind them.More and more zombies were being squeezed into the pit. If someone was looking at the ground from a high altitude at this moment, they might be frightened by this scene. The zombie swarms covered the entire area like army ants.

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

Qin Yi boarded the helicopter, and he looked at the second floor of the genetic research institute.General Shao was not on the evacuation list arranged by himself, and Qin Yi knew that he was still in the research institute.

Qin Yi shook his head, his expression was very quiet, his short pale hair was a little bleak in the wind blown 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 group was finally able to transfer all the scientific researchers, and Shao Yifu's task was almost completed.According to the remaining time, the helicopter brigade will have another chance to return, and then the remaining scientific research equipment will be operated together.

"What about the soldiers," Ge Congxian asked.

"Let me take them to try to transfer from the ground," Shao Yifu said solemnly.

"Aren't you going with us?" Ge Congxian was a little surprised.

"The capacity of the helicopter is limited, so 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 this?"

"I will stand with my soldiers until the end," Shao Yifu said, "If possible, I will take them all out."

The location of the second line of defense is not as ideal as the first line of defense in the Huizhong Road Tunnel. Fortunately, the engineering team has placed explosives in many places between the two lines of defense in advance, around the National Stadium, the swimming pool of the Olympic Sports Center, the roller skating square and Arrangements have been made for locations such as digital museums.

The blasting of the Huizhong Road Tunnel brought unexpected results. When the situation in front was reported to Shao Yifu, Shao Yifu decisively dispatched a third batch of about 100 people to the Olympic Park Station of Metro Line 15 and extended the line 15. High-explosive explosives are placed on the subway tracks. This is the third line of defense, and it is almost the last line of defense. Less than one kilometer past the subway is the Yanjing Genomics Institute of the Chinese Academy of Sciences, where the Tsinghua Concorde Department is located.

The last 61889 soldiers of the 100th unit stayed at the research institute, making final defense preparations.The explosives and ammunition hoarded in the research institute were all distributed, and there was nothing left.In the Olympic Village Science and Technology Park, some buildings were temporarily transformed into the last fortresses, and these fortresses were transformed into fully enclosed structures, like living coffins.The soldiers who entered the inside of the fortress had already given up the chance of escape, and stayed inside as abandoned children to buy time for the transfer work.

The helicopter brigade brought by Ge Congxian is still carrying out the transfer work in an orderly manner, and there is no fighter in the entire research institute to assist them.The sound of gunfire and explosions in the distance is getting closer and closer. The scientific researchers who have already boarded the plane are sweating for the soldiers on the front line. They all know that their lives are won by the soldiers with their own sacrifices. , Some people have shed tears in sadness.

The helicopters took off one after another. Shao Yifu and Ge Congxian looked out of the window at the helicopters gradually disappearing into the sky. Their moods were different.Shao Yifu's mood is much more relaxed, more than half of the task is completed, the remaining work is to consider how to take out as many fighters as possible, the capacity of the helicopter brigade and the limitation of time factors lead to the combatants of the research institute not boarding the plane Shao Yifu didn't want them to sacrifice their chances here.

Ge Congxian was still thinking about persuading Shao Yifu to evacuate with the second batch of helicopters. Shao Yifu's insistence made him feel a little dizzy, because before he came, he had received a special order from Rong Yun, and Rong Yun asked him to take Shao Yifu out. If it is impossible to pick it up, special means can be used.

"It seems that the chairman knows Lao Shao better," Ge Congxian sighed inwardly, chatted with Shao Yifu for a few words, then turned and left to make the next arrangement.

Shao Yifu looked back at Ge Congxian's back, and felt that Ge Congxian's expression was a little strange just now, but after thinking about it, he didn't find anything wrong.

When the helicopter flew over the Huizhong Road tunnel, the pilot looked down.The deep pit blasted by the high-explosive explosives has been filled with densely packed zombies. The corpses on the south side of the tunnel continue to move north and try to cross the deep pit. More zombies enter the deep pit, and the bodies of the zombies gradually fill the deep pit.

Some zombies heard the sound of the helicopter flying overhead, and raised their heads to look at the group. The flying helicopter didn't attract the zombies for too long, and their attention was always focused on the front.

The zombies on the north side of the tunnel had already started to be stopped by the retreating defense forces. The number of zombies that crossed the tunnel before the high-explosive explosives exploded in the tunnel was not many, probably only a few thousand.During the retreat, the soldiers began to stabilize their formation and counterattack.Time and lives are passing, the number of casualties of soldiers withdrawn from the first line of defense began to rise, the pressure on the north side of the tunnel was much lower than before, the soldiers fought and retreated relying on the terrain, and the soldiers on the second line of defense also Jump forward for cover.

In the end, there were more than 400 soldiers who successfully retreated to the second line of defense. In addition to the 300 soldiers on the original second line of defense, there were less than 800 soldiers in total, which was comparable to the defensive strength of the original first line of defense.

Xu Yongping continued to take over the command of the second line of defense and began to deploy defenses in areas near the line of defense.To the east of the China National Convention Center is the Yangshan River, which runs south from Aohai Lake and Wali Lake.Xu Yongping sent people to blow up all the bridges across the Yangshan River, turning the Yangshan River into a natural barrier on the east side of the second line of defense.Several bridges on National Stadium North Road, Datun Road, Datun North Road and Kehui South Road collapsed during the blasting, and the vehicles on the bridge and the reinforced concrete of the bridge body fell into the river.After the four bridges were destroyed, the front of the second line of defense was compressed to a width of 800 meters, and the defense width of each person was about 1 meter, which was half of the defense pressure of the first line of defense.

The group of corpses in the Huiyuan apartment area on the east side of the bird's nest was isolated to the east of the Yangshan River, and could not pose a threat to the defense line and the research institute within a few hours.The number of remaining zombies in the zombie group is about 6. They began to cross the deep pit of the Huizhong Road tunnel and entered the area near the National Stadium and the swimming pool of the Olympic Sports Center, only 500 meters away from the second line of defense.A small number of zombies deviated from the direction, left the group of zombies and moved westward, entering the Seventh District of South Lane of Science Park.

The zombies leaving among the corpses added a lot of variables to the defense, so Xu Yongping had to send a team of 50 people to keep an eye on them. Unit 61889 currently cannot mobilize enough power to eliminate these stray zombies. The task of the dispatched squad is to observe the movements of the zombies, and promptly alert Xu Yongping's department and the research institute.

The road in front of the National Convention Center is full of half-person-high roadblocks. These roadblocks can serve as shelters for the defending troops and block the advance of the zombie hordes.Flags were still flying on the three flagpoles in front of the conference center, and the five-star red flag in the middle was particularly dazzling. Many soldiers glanced at it intentionally or unintentionally, and their beliefs became stronger.

The fire in the Huizhong Road Tunnel has been extinguished, and the average number of zombies in the zombie group have crossed the first line of defense. The zombies in the deep pit are scrambling to step on the bodies of other people to climb up. In the team going north.

Xu Yongping is waiting, now is not the best time to detonate the explosives placed over there.In order to achieve the best results for all arrangements, he has been highly focused, and his brain has been deliberating and calculating.The few cards in his hand are not enough to support him to win the war, but this does not prevent him from striving for a strategic victory.All kinds of arrangements and arrangements for the first move have achieved unexpected results, buying a lot of extra time for the entire operation.

The front of the group of corpses arrived near the roller skating square, and the soldiers on the second line of defense could already clearly see the entire figure of the frontmost zombie in the group of corpses.They came out from the hail of bullets, almost all of them were bruised, some of the zombies were still burning with green smoke, and some of the bodies of the zombies were no longer complete, but they just walked forward silently, and no one knew their final fate. Where is the destination.

A group of 6 corpses covered all the flat ground that can be seen in the field of vision, and some zombies entered the building, and the crowd of corpses was crowded with people.Some soldiers who have not experienced the first line of defense were stunned by such a scene. Everyone here has fought losses, but not all of them have fought so many zombies.

Xu Yongping and the officers seized the last time before the war and began to mobilize and encourage.These soldiers regained their previous confidence after a moment of disturbance. The idea of ​​defending their home and country has penetrated into the bones of each of them, so after a simple mobilization, their morale returned to the original level.

"With the North Road of the National Stadium as the boundary, the group of zombies approaches within 20 meters, all fire, and the engineering team detonates the preset explosives." Xu Yongping looked at the group of zombies directly in front of him and gave an order.

More than 6 zombies flooded over like the tide at high tide. They passed through the gaps in the middle of the building, like sea water flooding over rocks.

As the distance got closer, gunshots began to ring out in patches.The group of corpses has entered the optimal shooting distance, and there is no need for Xu Yongping to give an order to fire. The entire defense line spits out flames, harvesting the lives of the zombies like harvesting rice.
