A huge bridge spans both sides of a rolling river, but once there was no other bridge except for a few broken vehicles.

Several large cars, apparently specially modified, rushed up to the bridge, each with four or five people alight, each carrying a large package.

Those people had a very tacit understanding of their respective division of labor, quickly chose their own positions, and completed their tasks in various places on the bridge.

They moved swiftly and skillfully, as if the scene had been rehearsed many times, but in ten minutes, a group of people got into the car, and the car turned back and drove in the direction they had come.

When the car turned around, it knocked several zombies in the way and drove straight into a building.

The entrance to the building has also been visibly redesigned, with a rudimentary paved passage that can only accommodate one car.

The vehicle entered the passage and stopped steadily under the ceiling that had been opened through several gaps, and then several rope ladders fell, and several people in each car moved quickly and quickly climbed up in an orderly manner.

"Where are the generals and commissars?" asked one of the leaders of the convoy as he went upstairs.

"I'm waiting for you at the top of the building, let's go!" replied to one of the people who had lowered the rope ladder, and at the same time quickly retracted the rope ladder.

On the roof of the building, a man in an old military uniform stood side by side with a man in a tunic suit, looking resolutely ahead.

"This time, we should have plenty of time, right?" Cai Xun said leisurely.

"That's natural, we spent so much time and so many methods to build a safe base, and this time it took a year to attract all the zombies here, leaving a city that can be completely dominated by us. Jiang Dacheng said.

"As long as this plan is successful, we will be able to build an impregnable castle, and when the time comes, no matter how many zombies there are, we will be able to ensure that everyone has a stable life and no longer be afraid of those monsters. ”

"That's right, once this plan is successful, the zombies south of the Yangtze River will no longer be able to form an effective threat, and it will take a certain amount of time for the zombies from other places to gather, and we will get more than half a year to build a perfect barrier that zombies can't pass through based on those high-rise buildings. Cai Xun said.

I don't know what attracts zombies, but zombies do always gather in places where there are living people, and to survive, they must either keep migrating and avoid large-scale zombie groups, or there is a tall and strong fortress to ensure that zombies cannot enter.

They tried their best to attract all the zombies to this side, there is a big river barrier, the turbulent river will become the best barrier on their side, once the zombies enter the big river, they can't cross the middle of the river will be washed away by the current, and occasionally zombies are washed ashore, and they can't create any threat.

"Okay, it's time for Gu You to come up and see how he is arranged?"

"Well, it should be no problem, Gu You won't make a mistake!"

The sound of footsteps came from behind, and as soon as the two of them turned their heads, they saw Gu You carrying a silver box coming out of the staircase.

There were no extra words, and after saying hello, Gu You opened the suitcase in his hand directly in front of the two of them, but it was a computer.

The computer screen is a three-dimensional bridge, and at various key points on the bridge, there are some small red dots flashing constantly.

"All the bombs have been laid out according to the predetermined plan, and the mission is accomplished!"

"You're doing a great job, go ahead and finish this last step. ”

Gu You nodded, firmly nodded to confirm, and then entered a ten-second countdown on the screen.

The three of them immediately stood up and looked in the direction of the bridge, and ten seconds later, all the bombs on the bridge exploded almost at the same time, and a dense explosion of flames appeared on the bridge, and after the flames disappeared, the once magnificent bridge slowly sank into the water with a little burning flame.

"It's done!" Jiang Chengda slapped his palms and laughed.

"Yes, it's done!" Chae Hoon laughed too.

"Go, go, immediately carry out the second phase of the plan, transfer everyone as soon as possible, and then build the fort. ”

With that, the three of them walked together to the other side of the building, where a pitch-black pillar of twenty centimeters thick stood firmly on the roof, and on the pillar, a thick rope stretched out to the middle of the other building.

Looking down, there are also several ropes stretching from other buildings to this building, and the eyes continue to look away, between the city buildings, more than a dozen ropes are connected, and there are several connected to each other, which looks like a huge spider web, forming a set of strange traffic roads, and the three of them have slid away from the ropes.

A few hours later, a large number of heads suddenly appeared from the buildings, and they methodically hung the packages on the ropes, and then they themselves followed the rapid glide past, and finally, everyone gathered in the building closest to the river.

There were at least hundreds, if not thousands, of people, but everything was so orderly, there was no discordant voice, and everyone was doing their job, like a well-disciplined army on the march.

"Report, all non-combatants have been transferred, please instruct. A soldier watched as the last man arrived safely on the other side of the bank, and said to Cai Xun, who was still here.

"Okay, after the first squad is broken, the rest of the squad will cross the river in turn!" Cai Xun finished the order, and also crossed the river quickly under the arrangement of the soldiers.

On the other side, everyone was placed in a residential building, and the fighters were scattered around to stand on guard in case any fish slipped through the net and were not lured to the other side.

······

Half a year later, a huge castle with a rough but indestructible feeling was built around the area where everyone lived, and most of the original towering buildings were gone, turning into raw materials for the construction of the castle.

From the inside, the castle is very rough, and the walls are full of shadows of some architectural debris, and in some places some rusted steel bars can still be seen.

From the outside, the castle is spectacular, with smooth and solid walls, nothing to draw on, and a certain angle of inclination that makes it difficult to climb.

"Lao Cai, this completion is still a bit hasty, and there are still many defects in many places. Jiang Chengda looked at the huge project completed in front of him, and said with joy and regret.

"That's no way, there are more and more zombies coming from other places, just a few squads can't stop it, building the castle as early as possible is the most important thing, those defective places can be improved slowly, there will be no problem. Cai Xun comforted, also with a happy face, Jiang Chengda's flaws could not reduce his happy mood at this moment.

Humanity finally has a foundation that can continue.

······

"Report, received a message, sent from Washington. ”

"What information, read!"

"This is Washington, and humanity has reached a critical moment of life and death, and we ask all the survivors who have received this message to go to Washington for the future of humanity and for the hope of humanity and help us ······"

"Lao Cai, what do you mean by this?"

"There is no doubt that Washington already has a survivor base, and this base should be in trouble at this time, so send a distress message to survivors around the world. Cai Xun analyzed.

"Shall we send somebody, then?"

"Hmm······" Cai Xun thought for a while, and then said slowly: "There are not many survivors of the human race now, each of them is a precious treasure, you shouldn't give up, just let Gu You lead a team over, let him save as many people as he can, save as many people as he can, and do his best." ”

"Well, I have to explain to him, come back as soon as you save people, don't delay, after all, there are not many people on our side, and there are more and more zombies outside. ”

A few hours later, helicopters with five-star red flag signs took off from the base and flew towards the east.
