Rumble! A loud bang came from behind the crowd, followed by a shaking of the ground, and the exhausted warriors fell to the ground.

"Hurry up, we don't have much time." Wei Tao shouted, the loud noise and sudden vibration just now reminded him of the huge sandworm under the zombie general, among all the enemies observed, only a monster like a sandworm could make such a big movement.

Despite the three-meter-thick steel gate, no one knows if it will be able to stop the giant monster like the Sandworm, and even if the gate can stop them, it is unknown whether the outer walls of the bomb shelter will be strong enough.

Thanks to the efforts of all the survivors, the Alliance has been trying to expand the interior of this bomb shelter and open up an escape route. Due to the lack of corresponding equipment, the entire project was operated by manpower one shovel at a time, so the progress was unusually slow.

The newly excavated tunnel is not long, about 2 kilometers away, from the underground of the Jianglu Machinery Factory to the Xiangjiang wharf, where a fully restored freighter is moored on the river, ready to go downstream.

"Old Meng, how's the situation?" The reinforced concrete structure made it very difficult to communicate with the outside world in the air-raid shelter, but the internal communication was still very smooth, and Wei Tao ran quickly with the surviving soldiers.

"The situation is not good, the number of people was counted just now, and there are still a few people missing, how are you doing?" Meng Longwei's voice looked a little depressed, it only took half a day for the zombie army to break through the defense system that he had painstakingly operated for more than a month, and a dull crashing sound came from the other end of the passage to tell him that this time, the zombies did not intend to give up.

"We still have more than 50 fighters, and we are now searching for people who have fallen behind." The frequency of the impact behind him is getting faster and faster, no one knows how long the door can resist, everyone knows that once the gate is breached, countless zombies will surge, no one can survive, and among the few people whose whereabouts are unknown, there may be their own relatives, so no one is willing to risk giving up any hope.

"Give it up." Meng Longwei said anxiously: "I am the last to arrive here, I can guarantee that no one is left behind here." ”

There was a long silence on the other end of the intercom, and everyone understood what Meng Longwei meant.

……

"Lao Meng, haven't you gotten through yet?" In the bustling crowd, Wei Tao finally found Meng Longwei who was directing the construction, due to the lack of mechanical equipment and precise positioning system, the whole project was completely dug out by the survivors with a shovel, there was no reference in the tunnel, and the most primitive compass could only be relied on to identify the direction, when Wei Tao arrived with the remaining soldiers, the workers were still in the construction of the tense construction.

"I suspect we're going in the wrong direction." Meng Longwei wiped the sweat from his forehead, thousands of survivors were crammed into this narrow tunnel, the air was muddy, and behind him was the zombie army that was eyeing the tiger, and it was possible to break through the last barrier at any time, and at that time, everyone would be slaughtered.

The total length of the tunnel is 2,324 meters, which is the most accurate figure that the alliance has spent a lot of effort to determine, according to the original plan, the whole project will take 28 days to complete, and the exit will be in a container on the dock closest to the river, and even a three-year-old child will only need to complete the boarding in 1 minute.

Unfortunately, the plan could not catch up with the change, perhaps there was a deviation in the direction, the tunnel had been dug for almost 2,400 meters, but the reference object that Wei Tao had reserved at the target point was still not found.

"Can it be faster?" Wei Tao knew that even if he missed the reference object he set, as long as the general direction was correct, the tunnel could still be dug to the riverside, so that he could also escape.

The tunnel was hot and humid, the air was getting more and more turbid, the adults were a little unbearable, the young children had already cried, for a while, the children's crying, the adults' shouting, the noise generated by the workers' earthwork and the more and more frequent impacts, the atmosphere in the whole tunnel became more and more desperate and depressing.

"No, we can't wait any longer." The tunnel is narrow, so only a dozen or so workers can carry out earthwork at the same time, and the excavated earthwork is pushed and dumped not far away by other workers with small carts. ”

"Blasting?" Wei Tao grabbed a handful of dirt from a worker's trolley, put it in front of his nose and sniffed it, shook his head and said, "No!" The soil is soft and wet, and blasting will cause tunnel collapse! ”

Meng Longwei had already talked about this result, and at the beginning someone proposed to use blasting to speed up the progress of the project, but the first blasting failed, and the tunnel of nearly 50 meters or so collapsed because of blasting, and the workers had to spend most of the day to dredge and strengthen the tunnel.

In desperation, everyone had to stand aside and wait for the final result, the workers in charge of the earthwork had been replaced, and many anxious soldiers even joined the team to transport the earthworks, regardless of their own injuries.

"Not good!" I don't know when it started, the sound of sandworms hitting the steel door disappeared, and the noisy environment made Wei Tao ignore his vigilance against zombies for a while. I don't know what made the zombies quiet, but it's not good news.

"That's it! That's it! At the end of the tunnel, the cheers of the workers could be heard, and when they heard the news, the survivors became excited, gathered together, exchanged ears, and looked forward with their feet folded.

Wei Tao pushed aside the crowd and rushed to the construction site with ease, and a fist-sized opening appeared at the end of the tunnel, and the slightly fishy river breeze blew into the sultry tunnel along the mouth, bringing a slight coolness to the sweaty workers.

"Reinforcement of the roof beam, enlargement of the hole, quick!" Wei Tao lay at the entrance of the cave and looked out, although the sky was dark, the sky was full of dark clouds, and the visibility was very poor, but the sound of the water washing the river bank was so clear, Wei Tao excitedly shouted: "Comrades, work hard, we are at the riverside!" ”

"Lao Meng, we succeeded!" Wei Tao couldn't wait to bring the news to Meng Longwei and the other survivors, and the people who had been suppressed for a day needed good news to boost their morale.

But before everyone could digest the good news,
