Before the end of the world, when the Hebei Provincial Government built the underground base, it considered the possibility that the underground base would be besieged by unknown creatures.

So the government at that time opened more than 100 subway platforms in the underground base, enough to accommodate more than 4 million people to evacuate safely at the same time. At the same time, at the exits of those subway platforms, they also specially built fortress-like things, all of which were made of the strongest materials, which could theoretically withstand the explosion of bombs, and were the best defensive structures.

In addition, these subway platforms, along with a series of independent subway lines, are completely enclosed and not connected to any subway platform in Hebei Province, with the entrance at the underground base and the exit at Shanxi, far away from Hebei Province.

From this point, it is enough to see the foresight of the engineer who planned these at that time, if it weren't for him, I am afraid that those survivors in the survivor base in Hebei Province would really be trapped in the underground base.

When the news of the evacuation came out, it was the first time that the survivors knew that there was a subway platform dedicated to evacuation in the original underground base, and they were all overjoyed at the moment, and the hope of escape rose in their hearts.

Although there are more and more unknown creatures outside, as long as you rush into the subway platform, you can survive!

In the hope of survival, all the survivors temporarily suppressed the fear in their hearts, ignoring the groups of unknown creatures outside, and ran towards the nearest subway platform to them.

Under the cover of soldiers and mutants, these survivors were temporarily safe, and a few minutes of safety were enough to save most of them!

While most of the survivors closest to the subway platform rushed into the subway platform, many more were chased by unknown creatures and slaughtered.

Listening to the screams coming from behind and around them, the survivors fled faster. After all, no one wants to be left behind, and once you run slowly, you are really dead.

And the hope of survival lies ahead, and they can't afford not to use all their strength to feed.

In this way, a strange sight appeared in the underground base.

When more than hundreds of thousands of soldiers were fighting with unknown creatures, mutants with various cold weapons entered and exited the unknown biota, and ordinary unknown creatures could not withstand their blows, even the largest crocodile with the highest defense and attack power, could not withstand the attacks of two mutants.

And around these people, in the rain of bullets and unknown creatures, there were survivors screaming and running, all of them rushed out of the cave where they were hiding and ran towards a certain place.

In the process of escaping, some survivors were unfortunately caught up by unknown creatures, and the lucky ones were bitten to death by spider creatures or trampled to death by crocodiles, but unfortunately they encountered blue bee creatures, and were sprayed with venom, which could only be screamed and slowly melted, and that kind of torture made everyone who saw it couldn't help but feel numb in their scalps and a chill in their backs.

Soon, most of the survivors had retreated into the subway platform, numbering more than two million. However, millions of people still died under the attack of unknown creatures, and those people were all slow runners, or people who did not dare to run halfway through or ran back, these people without exception became a delicious meal in the belly of unknown creatures, and the blood directly stained the ground of the underground base.

Seeing that most of the survivors had escaped safely, the soldiers and more than fifty mutants began to quickly retreat towards the platform entrance.

When all these soldiers and mutants retreated into the subway platform, Liu Chang and the person in charge of more than a hundred subway platform entrances immediately ordered the subway entrance to be closed.

Just listen to "Boom! Boom" several loud sounds, and huge iron doors smashed down, closing the entire subway entrance tightly.

When the unknown creatures rushed over, they could only roar and keep hitting the steel gate, but they couldn't rush in, and the survivors were given some respite.

Among them, there are some people who can drive trams, and without exception, they have become sought-after goods, and the survivors have high hopes.

As for all the soldiers, they began to rest on the spot and quickly regain their strength, while those who were good at repairing were requisitioned by the army to overhaul trams and electrical circuits, and every moment and every second were caught tightly.

Because they knew that the iron gate would not last long, and that the spider creatures had the ability to dig holes, and the platform was surrounded by stones and dirt!

And the venom of those blue bees is corroded by its strong corrosive ability, and the iron gate can't hold out for too long under the corrosion of those venoms!

So, everyone is trying to recover as much as possible, and all the engineers are trying to overhaul the trams and circuits as fast as they can, trying to get them up and running as quickly as possible

Since the 100 stations were connected by passages, the news of the maintenance came quickly.

"Report to the commander, all the 113 platforms have been inspected, except for the 3 platforms 40, 41 and 69, the remaining 110 platforms are all available!"

Liu Chang nodded and said, "Then let the survivors of the one hundred and ten platforms be the first to evacuate, and let all the repair personnel speed up to repair the circuit problems of those three platforms!" ”

"Yes!"

After speaking, Liu Chang was about to turn his head to say something to Lu Wentao, but suddenly heard a loud noise in the passage, and he immediately turned his head to look at it with a puzzled face, but found nothing.

"What's going on?" Lu Wentao frowned, looked around, and found nothing.

"I guess those unknown creatures are hitting the passage......

As soon as he finished speaking, a soldier covered in blood ran in.

"Report to the commander, oh no, platform 27 was knocked open by an alligator! The tram has been smashed, and most of the survivors are killed or injured! ”

"What?!" Lu Wentao and Liu Chang's faces changed together, not only them, but everyone in the one hundred and one platform changed their faces greatly.

"Quick, get the tram started! How much can you escape, hurry! ”

At the sound of the order, the trams in the platforms where the circuits were still intact started in an instant, and the slowly carrying the survivors quickly galloped away along the subway line. As for Platform 27, it was in shambles, the tram was in tatters, and the ground was covered with human corpses and bloodstains.

At this moment, the subway station with the three circuit problems immediately panicked, and all the survivors were agitated, urging the workers to repair the circuit quickly, and Liu Chang and Lu Wentao and some soldiers also stayed, and they had to retreat with the remaining survivors!

"Commander, unknown creatures have poured in from platform twenty-seven, what should I do?"

Listening to the reports of the soldiers around them, Liu Chang and Lu Wentao frowned, and their faces were extremely ugly!

Liu Chang clenched his fists and ordered: "No matter, order someone to blow up the platform between the 28th and 39th, let the gravel block the entrance, and buy some time for the circuit repair!" ”

"Yes!"

The order was quickly given, and the soldiers began to quickly plant the explosives.

Due to the rapid influx of unknown creatures, the soldiers used grenades and artillery instead of explosives to throw them into the passage.

Listening to a few loud "booms", the rock layer between the 28th and 39th began to collapse, turning into pieces of rubble blocking the passage between the 28th and 40th subway platforms, buying a certain amount of time for the repair work!
