There are several auxiliary passages in the subway tunnel of Line 1.

When Line 1 was built, the construction team had considered the occurrence of accidents, and these auxiliary passages would help victims escape from the subway tunnel in time, thereby preventing a series of subsequent rescues, collisions and other incidents that may occur.

However!

The engineers who built this subway tunnel probably never dreamed that their humanized design would bring huge hope for human survival.

With the help of these auxiliary tunnels, survivors lurking underground can climb to the surface, and then search for supplies for survival in corners where thousands of zombies are not paying attention. .??.

The auxiliary passage that Song Ziyu is taking now is one of the branches.

Every few tens of meters here, one or two military soldiers are sitting to defend and respond.

Chen Xi took out the staff's identity plate and went straight to clear the way, and soon asked about Mr. Li's whereabouts from the soldiers.

When he learned that Mr. Li had ventured to the surface in order to meet the exploration team who could not return, Chen Xi was completely panicked.

"You still have yours. Take my identity plate and report it immediately to the staff headquarters and ask the headquarters to mobilize manpower for support!" Chen Xi thrust his identity plate into the hands of the soldiers and warned with great caution: "Be sure to hurry, there are thousands of people on the road.

Don’t delay.”

After receiving the order, the soldier turned around and ran towards the station with his identity plate in hand.

Looking at the soldiers leaving, Chen Xi gritted his teeth and said, "We are going to the surface!"

As soon as these words came out, the soldiers stationed at the entrance of the passage were shocked: "Sir Chen, if you go up there and narrowly escape death, you must not go!"

"Why can't I go?" Chen Xi asked.

"For your safety," the young officer stationed on guard said.

Chen Xi sneered and said: "Stop talking nonsense, go get me three sets of biochemical protective suits!"

It seemed that Chen Xi was determined to go up.

The officers stationed at the passage were far inferior to Chen Xi, so naturally they couldn't resist. No one present could convince the girl, so they had no choice but to be ordered to get biochemical protective suits.

The three of them put on protective clothing and walked towards the surface.

There is a shaft at the entrance of the auxiliary passage, through which you can climb to the inaccessible auxiliary mezzanine. Many rooms here were originally used for fire insulation and earthquake prevention, but now they have become important passages to avoid zombies.

Along with the long winding stairs and slopes, everyone headed towards the surface.

Finally at the exit, Chen Xi once again saw the soldiers posted here to guard the retreat.

"Where is Mr. Li?"

Chen Xi grabbed the soldier and asked.

“Over there at Zenith Department Store!”

said the soldier.

"Damn it, why didn't you stop him?"

Chen Xi was furious.

"Who can stop me?" the soldier said angrily.

Chen Xi pushed the soldier away and continued walking towards the surface, followed closely by Song Ziyu.

The opening for the safety passage is opened in a building next to the subway station.

This building is the cleanest area where zombies have been cleared so far, so everyone can reach the surface safely.

…

This is the first time Song Ziyu has seen what the ground will look like fifty years from now!

The dim sky was like four or five o'clock in the morning, with poor visibility. There was a strong smoke all around, and what fell from the sky was heavy black snow.

"Even if you are wearing protective clothing, try not to come into contact with these dusts that carry strong radiation, otherwise your life will be greatly shortened." Chen Xi, who wrapped himself tightly, said in a loud voice.

Seeing Beidu reduced to hell, Song Ziyu couldn't help but ask: "Who did it? Who wants to destroy this world?"

Chen Xi shook his head, and then murmured: "There is no point in talking about this question now.

Okay, let’s find a way to support Mr. Li and the others.”

As he spoke, Chen Xi took out a walkie-talkie and was trying to contact Mr. Li via frequency modulation.

Soon, Chen Xi received a response, but the news was not good!

On their way to pick up the exploration team, the people led by Mr. Li were blocked by a wave of zombies in the Zenith Department Store.

"Damn it!"

Chen Xi stood on the business floor outside the underground station, looked at a building in the distance and said, "That's the Zenith Department Store. We must find a way to get Mr. Li and the others out of trouble."

Song Ziyu looked at the building in the distance and found that the streets were densely packed with zombies. The number was so large that it was impossible to count.

The streets have been blocked, and such a horrific scene is jaw-dropping.

"I'm afraid this situation is not easy to deal with!" Afa, who had been silent all this time, suddenly spoke.

Chen Xi was also at a loss.

Ah Fa said calmly: "With so many zombies, it is almost impossible to retreat from the road."

"Once a fight breaks out, more and more zombies will gather."

"Although these monsters have bad brains, their hearing is still quite sensitive."

"The swarming zombies will make it difficult to escape."

"If you force a rescue, you might even get involved."

Chen Xi nodded and couldn't help but sigh.

Just when everyone was at a loss what to do, Song Ziyu spoke:

"I have an idea."

"What clever idea can you come up with?" Afa asked.

Song Ziyu thought for a while and said: "Let's go to the sky."

Immediately, Song Ziyu expressed his thoughts.

After explaining the idea, Chen Xi showed joy on his face, and Afa even liked it.

"You can try this method. I'll call someone to help." Chen Xi said.

…

A large number of soldiers heard

After the order was given, they came to the surface to gather. Each of these soldiers was carrying a large amount of hemp rope and load-bearing pulleys removed from abandoned subway locomotives and elevator shafts.

Song Ziyu took everyone to the rooftop of the office building and then measured the opposite side.

If you want to go from the subway station entrance to the Zenith Department Store building, you need to set up ziplines at least five times, which is an almost impossible task.

Because... as far as the zipline that needs to be set up at a time is concerned, the street between the buildings is eight meters wide!

With such a long distance and no one on the other side to respond, it is simply impossible to achieve.

But this is for ordinary people!

Song Ziyu looked at Ah Fa and said, "Try?"

Ah Fa was a little speechless: "Song Ziyu, you regard me as your scapegoat. Why do you find so many satisfying things to do?"

"Saving people is your mission."

Song Ziyu said.

Ah Fa touched his head, wanting to blow Song Ziyu's head off.

"I feel unbalanced if I do this work alone. You have to suffer with me."

Afa named him.

Song Ziyu nodded and said: "Then I will sacrifice my life to accompany you."

So the two people fixed one end of the hemp rope to the water tank on the rooftop, then made a full circle of the hemp rope, and made an incredible move in front of everyone!

I saw the two of them running for a while, and then jumped out directly from the rooftop.

"That's crazy! The street is eight meters wide!"

"Hey, hey, he fell down."

"well!"

"If a person falls from a hundred-meter-high building, he will still be smashed to pieces?"

Everyone was talking a lot, thinking that these two guys were doomed!

However……

When everyone walked to the rooftop, they saw an incredible scene!
Chapter completed!
