Endless journey through the dimension

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

Hundreds of grenades were thrown at the corpse group, and a few seconds later, it bloomed on the front line of the corpse group.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 zombies is relatively limited. Some zombies rushed through the smoke and came to the Huizhong Road tunnel. The tunnel was five or six meters high and the walls blocked the zombies outside.There were several openings on the wall outside the tunnel, and some zombies poured into the openings.

More and more zombies came under the wall, the first zombies were crushed underneath, and the zombies coming from behind stepped on the zombies underneath and climbed to the top of the tunnel.The "Human Wall" was folded up, and the zombies climbing on the top of the tunnel crossed the defense line set here and chased the retreating soldiers.

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

"Prepare to detonate the Gaobao explosive 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 to detonate is the most appropriate time. In addition to maximizing the damage to the zombies, the tunnel after the explosion can also be used to separate the zombie group. The number of corpses close to the second line of defense will not be many, and the defensive pressure is not very great. The fighters who retreat can have time to rest before returning to the battle.

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

During the retreat, a total of more than 100 fighters and four supernaturalists died on the road. These were the elites in their own troops.

Xu Yongping was heartbroken. Almost every one of the soldiers he brought over could be called by name.Now he brought them, but he couldn't bring them back.

On the Huizhong Road tunnel, a fire dragon rose into the air along the first line of the tunnel. A huge explosion sounded along with the vibration to the second line of defense. The sound waves and tremor passed over the National Convention Center and passed to the Yanjing Genomics Institute of the Chinese Academy of Sciences and the Tsinghua Union Ministry. All of you felt the shock this time.No one would think this was an earthquake, everyone was guessing what was happening ahead.

In the meeting room, the cigarettes in his hand have been burned, but the cigarette butt is still in Shao Yifu's hand.

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

Shao Yifu threw the cigarette butt in his hand into the ashtray, got up and walked out of the conference room door.

The Huizhong Road Tunnel was completely destroyed by Gaobao explosives. At the location of the original tunnel, only a 2,000-meter-long deep pit was left, with burning corpses on both sides of the pit.In the northern part of the deep pit, the zombies that had passed through the tunnel were washed to the ground by the shock wave of the explosion. At this time, they all got up, and followed the zombies in front to pursue the retreating soldiers.

In the southern part of the pit, the subsequent huge group of corpses continued to advance slowly, and the forefront zombies reached the edge of the pit.They stopped, but were squeezed into the pit by the endless zombies behind them.More and more zombies are squeezed into the pit. If someone observes from a high altitude to the ground at this moment, they may be frightened by this scene. The zombie group covers the whole area like marching ants.

The Tsinghua Concord Department continues to be busy. Ge Congxian’s helicopter unit has arrived and landed in the Olympic Village Science and Technology Park of the Chinese Academy of Sciences. Qin Yi and other researchers have begun to be arranged to board the plane.Most of the scientific research equipment was evacuated in the second batch. At this time, most of them had been disassembled and packaged and placed on the open space.

Qin Yi boarded the helicopter and looked at the second floor of the Institute of Genetics.General Shao was not on the retreat list he arranged, and Qin Yi knew he was still in the research institute.

Qin Yi shook his head, his expression was very silent, his pale short hair was a little depressed in the wind brought by the helicopter propeller.

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

This batch can finally transfer all the scientific researchers, and Shao Yifu's task is almost completed.According to the remaining time, the helicopter brigade may also have a chance to return, when the remaining scientific research equipment will be operated together.

"What about the soldiers," Ge Cong first asked.

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

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

"Helicopter capacity is limited, so install as many important equipment and documents as possible," Shao Yifu said. "The soldiers are still fighting desperately on the front line. As their commander-in-chief, I walked first. What counts?"

"I will stay with my soldiers to the end," Shao Yifu said: "If possible, I will take them all out."

The location of the second line of defense is not ideal for 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 Olympic Sports Center swimming pool, the roller skating square, and Arrangements have been made for locations such as the digital museum.

The blasting of the Huizhong Road Tunnel brought unexpected effects. When the situation ahead was fed back to Shao Yifu, Shao Yifu decisively sent a third group of about 100 people to the Olympic Park Station of Metro Line 15 and extended Line 15. High explosives are placed on the subway track, which serves as the third line of defense and 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 Concord Department is located.

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

The helicopter brigade that Ge Congxian brought was still in an orderly transfer process, and no one soldier could be dispatched to assist them in the entire institute.The gunshots and explosions of the battle in the distance were getting closer and closer. The researchers who had boarded the plane sweated for the soldiers on the front line. They all knew that their lives were won by the soldiers with their own sacrifices. Some people have shed tears in sadness.

Helicopters took off one by one. Shao Yifu and Ge Congxian looked at the helicopters gradually disappearing into the sky outside the window, and their moods were different.Shao Yifu's mood was much more relaxed. Most of the task was completed. The remaining work was to consider how to take the soldiers out as much as possible. The capacity of the helicopter brigade and time constraints caused the institute's combatants to not board the plane. Shao Yifu did not want them to sacrifice here.

Ge Congxian is still considering persuading Shao Yifu to evacuate with the second batch of helicopters. Shao Yifu’s insistence made him bigger, because before he came, he had received special instructions from Rong Yun. Rong Yun asked him to take Shao. If one husband takes it out, it's really impossible to use special methods.

"It seems that the chairman knows Old Shao better," Ge Congxian sighed in his heart, and after a few conversations with Shao Yifu, he turned and left to make the next arrangement.

Shao Yifu looked back at Ge Congxian's back. He felt that Ge Congxian's expression was a bit strange. After thinking about it, he didn't find anything wrong.

As the helicopter flew over the Huizhong Road tunnel, the pilot looked down.The deep pit exploded by Gaobao explosives has been filled with densely packed zombies. The group of corpses on the south side of the tunnel continued to move northward to cross the pit. More zombies entered the pit, and the bodies of the zombies gradually filled the pit.

Some zombies heard the sound of the helicopter flying over their heads and raised their heads to look at the fleet. The flying of the helicopter did not attract the zombies for too long, and their attention was always focused on the front.

The zombies on the north side of the tunnel have begun to be blocked by the retreating defensive forces. The number of zombies who crossed the tunnel before the explosion of the high explosive 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 life are passing by. The number of casualties of the soldiers who withdrew from the first line of defense began to rise. The pressure on the north side of the tunnel was much smaller than before. The soldiers relied on the terrain to fight and retreat, and the soldiers on the second line of defense also Come forward to cover.

In the end, there were more than 400 soldiers who successfully retreated to the second line of defense. Adding to the 300 soldiers on the second line of defense, there were less than 800 soldiers, which was equivalent to the defense force of the first line of defense.

Xu Yongping continued to take over the command of the second line of defense and began to deploy defenses near the line of defense.To the east of the National Convention Center is the Yangshan River, which is set aside from Aohai and Wali Lake and extends to the south.Xu Yongping sent people to blast 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 the National Stadium North Road, Datun Road, Datun North Road, and Kehui South Road collapsed one after another during the blasting. Vehicles on the bridges and the reinforced concrete of the bridge fell into the river.After the destruction of the four bridges, the front of the second line of defense was compressed to 800 meters wide, and each person's defense width was about 1 meter, which was half the defense pressure of the first line of defense.

The corpses in the Huiyuan apartment area on the east side of the Bird's Nest were isolated to the east of the Yangshan River, and they were unable to pose a threat to the defense line and the research institute within a few hours.The number of remaining zombies in the group of zombies is about 60,000. They began to cross the deep hole of the Huizhong Road Tunnel and into the area near the National Stadium and the Olympic Sports Center Swimming Pool, only 500 meters away from the second line of defense.A small number of zombies deviated from the direction, left the group of zombies, moved westward, and entered the seventh area of ​​the South Science Park.

The zombies that left the corpse group added a lot of variables to the defense, and Xu Yongping had to send a team of 50 people to stare at them.The 61889 troop is currently unable to deploy enough power to eliminate these outlying zombies. The task of the dispatched team is to observe the movements of the zombies and give early warning to Xu Yongping's department and the research institute in time.

The road in front of the National Convention Center is full of half-person high roadblocks. These roadblocks can not only serve as a shelter for the defensive troops, but also block the advancement of the zombie group.Flags were still flying on the three flagpoles in front of the conference center, and the five-star red flag in the middle was exceptionally dazzling. Many soldiers looked at it intentionally or unintentionally, and the belief in their hearts became stronger.

The fire in the Huizhong Road Tunnel has been extinguished, and the average number of zombies in the zombie group has crossed the first line of defense. The zombies in the deep pit scrambled to climb up on the bodies of other people, and a few zombies climbed out of the deep pit and joined to continue. In the northward team.

Xu Yongping was waiting. Now is not the best time to detonate the explosives arranged there.In order to get the best results from all the arrangements, he has always been highly focused, and his brain has been calculating calculations.The few cards in his hand are not enough to support him in winning this war, but this does not prevent him from fighting for a strategic victory.All kinds of advance arrangements and arrangements have achieved unexpected results and bought a lot of extra time for the entire operation.

The front of the corpse group arrived near the road roller skating square, and the soldiers on the second line of defense could clearly see the entire figure of the front zombie in the corpse group.They walked out of the rain of bullets, almost all of them incomplete, some zombies were still burning with blue smoke, and some of the zombies' bodies were no longer complete, but they just walked forward silently, and no one knew what they were going to be. Where is the destination.

A group of 60,000 corpses covered all the plains that could be seen in the field of vision. Some zombies entered the building, and the group of corpses was full of heads and shoulders.Some soldiers who had not experienced the first line of defense were stunned by the scene. Everyone here has been beaten and lost, but not all of them have beaten so many zombies.

Xu Yongping and the officers seized the last time before the war and began to mobilize and encourage.These fighters recovered their previous confidence after a moment of disorder. The idea of ​​defending their homes and the country has penetrated into the bones of each of them, so with a simple mobilization, morale has returned to the same level as before.

"With the National Stadium North Road as the boundary, the group of zombies approached within 20 meters, all members opened fire, and the engineering team detonated the preset explosive." Xu Yongping looked at the group of zombies in front of him and gave an order.

More than 60,000 zombies flowed over like the tide at high tide, they passed through the gap between the buildings, like sea water over the reef.

The distance got closer, and gunshots began to ring in patches.The corpse group has entered the optimal shooting distance, and Xu Yongping does not need to issue a firing command. The entire line of defense is spitting out flames, harvesting the lives of zombies like harvesting rice.

The explosions in the middle of the zombie group one after another, the preset explosives were detonated one by one, and after the thick smoke passed, many large pits several meters in diameter were left on the ground.Near the big pit are the corpses that were shattered in the explosion, and the charred torso was full of smoke, making it difficult for people to tell which part of the zombie was.

"How long will it take for the next batch of firepower reinforcements to power on Jiang Wannian's Ministry?" Xu Yongping sent orders to the correspondent.

The corpses began to cross the National Stadium North Road, and the battle began to enter a state of anxiety.

"General Jiang replied that it is expected to take more than half an hour." The correspondent reported.

Xu Yongping nodded and stopped talking.He knew that Jiang Wannian’s response was very objective. The missile army’s attack preparations require a lot of time. This service is generally used to decapitate enemy core figures or military targets. Jiang Wannian will be able to deploy and arrange troops here after the mutation day. Efficiency is already very valuable.

In this battle, the enemy Xu Yongping faced was different from any time before.The corpse group does not have the concept of retreat. To defeat the zombies, the only way is to eliminate them all, otherwise they will continue to move forward, even if there is only one left.The power in Xu Yongping's hand is too far from that of the corpse group, and there is no possibility of completely destroying the corpse group.

Casualties began to appear at the front. A soldier was thrown to the ground by the zombies that turned over the bunker. The zombies behind swarmed and drowned the soldiers in his wailing. The explosion sounded from the pile of zombies that fell over him, and the flames rushed. After driving a circle of zombies around, the bodies of the nearest few had broken into multiple pieces, and the soldier pulled down the fuse of the grenade before he died.

All the soldiers were prepared to die before the battle. Everyone was prepared to have a self-detonating grenade, which could be used to self-destruct when they were besieged by zombies.

The geographic location of the second line of defense is different from the first line of defense. The first line of defense is a straight line of defense built on the Huizhong Road Tunnel, with only a thin layer, and the width of the line of defense is very wide, which puts a lot of pressure on defense.The second line of defense is a regional line of defense. The line of defense has a certain depth. Soldiers rely on various buildings in the area of ​​the line of defense to shoot at the corpses. Although the attack effect is not as good as the fire net of the first line of defense, it delays time. very effective.

A few more grenades exploded in the corpse group. After the explosive air wave stopped the nearby zombies for a while, they walked forward again, the bullets shuttled around them, and some penetrated their bodies. For the torso, only the bullet shot into the head can successfully harvest the zombie's life.
