Song Ziyu looked back, and with the help of low-light night vision, he could see gravel falling on the wall of the corridor where he had just fought in the darkness.
this……
The reinforced concrete wall suddenly broke into a big hole.
As a large amount of earth and rocks fell like rain, Song Ziyu's whole body felt bad.
You know, this is a subway tunnel!
The shield technology and construction standards are extremely strict, and the pressure-bearing standards are also first-rate!
Otherwise, it would be impossible to carve out such a huge space hundreds of meters underground.
But such a solid and pressure-bearing tunnel was actually broken open by something!
Song Ziyu's eyes widened with disbelief on his face.
A huge, round head like a drill drilled out of the hard reinforced concrete wall.
From a visual point of view, the diameter of this huge head is at least one or two meters. In terms of physique, it is definitely a beast from ancient times.
"Don't move, don't talk, don't say anything." Ah Fa was more nervous than ever before and grabbed Song Ziyu and pushed him into the corner of the railway.
The two pressed their bodies against the wall, not daring to make any sound.
The giant monster seemed unaware of itself.
After the head broke through the wall, it stared at the wall on the other side of the tunnel!
I saw it squirming its terrifying body, swallowing and opening its mouthparts, revealing a circle of slender gear teeth.
The gear teeth were turning wildly, like a large boring machine with sufficient power and oil, digging a tunnel at full power.
...This large-scale hole-digging live show also lasted for an unknown amount of time. As a large amount of soil was excavated, the body of the terrifying monster began to gradually emerge.
Song Ziyu finally got to see the whole picture.
This is a huge worm, at least several hundred meters long.
From the characteristics of the body and the characteristics of digging into the ground, Song Ziyu was almost certain that this thing was a mutated and disordered earthworm.
Earthworm, also known as earthworm.
Song Ziyu used to think that it was just a joke from the ancients, but now that I have seen it, I know that the ancients are sincere in deceiving me.
Such huge earthworms, dried earthworms that smell like durian, should be enough for Liu Peiqie's family to eat for half a year... Song Ziyu shook off the messy thoughts in his mind and quickly analyzed the characteristics of this monster.
First of all, "Children's Encyclopedia" will tell you that earthworms have no eyes!
This monster doesn't rely on its eyes to perceive in the dark!
But the monster's epidermis is extremely rich in sensory cells, which can sense slight sensitive vibrations and confirm its direction based on ground vibrations. At the same time, these cells also breed a large number of light-sensing cells, which can capture slight light sources in the dark.
This monster uses this method to capture prey, and this monster also has a characteristic that requires life: it is not picky about food, and will eat whoever it catches, including dirt.
In front of such a monster, maintaining absolute silence is definitely a wise way to save one's life.
So Song Ziyu squatted against the wall and fell asleep while squatting.
…
I don't know how long it took, but Song Ziyu woke up in a daze, and the big earthworm had already disappeared.
After making sure that the thing had gone far enough, Afa started to move his legs that were numb from squatting.
"I can't believe that you are so clever!"
Afa teased.
Song Ziyu smiled bitterly and said: "How can I say that I have also experienced survival in the world of apocalyptic wasteland? Don't underestimate me."
"That's good, that's good, let's continue on our way." Afa said.
The two continued walking along the railway.
Finally, after passing through more than a dozen stations and refugee toilets, the two turned onto Subway Line 2.
After entering Metro Line 2, the surrounding environment suddenly became harsh!
Zombies appear from time to time along the way and attack you in the dark.
However, Song Ziyu and Afa are not ordinary people, and these unevolved zombies have no substantial lethality to them.
But this does not mean that these monsters cannot harm other civilians.
Therefore, Song Ziyu wiped out all the zombies that passed along the way.
Just walking like this while killing zombies, the seven or eight stations he passed were all abandoned, and several settlements were destroyed.
"Where did these zombies come from?"
The closer they get to the West Rail District, the more tired Song Ziyu becomes from killing zombies!
It seemed like there was no way to kill all of these zombies. Several passages were filled with corpses and no one was taking them in. The stench was simply extreme.
Afa explained: "Line 2 is located underground in the most prosperous new urban area in Beidu. Every exit directly faces the downtown streets, and the subway entrance here is not as deep as Line 3."
"When Beidu built Metro Line 3, the depth was built at the level of temporary shelter air-raid shelters."
"Therefore, it is completely easy for zombies wandering on the surface to enter underground line 2."
"What should we do?" Song Ziyu couldn't help but ask.
It is very fatal to have zombies entering in a steady stream like this. You can be a thief for a thousand days, and you are unable to prevent the thief the day before. Zombies follow the entrance of the earth station and enter the ground every day. This is really fatal.
"What else can we do? Of course it's cold salad."
Afa sighed and said.
Song Ziyu said from his own point of view: "Defenses should be established at the entrances of each subway station to resist the invasion of zombies."
"You are really smart." Afa smiled and said, "You are not the only one who can think of the method, but your method may not be useful."
"Why?" Song Ziyu straightened his head like a goose.
Ah Fa said calmly: "Do you know where these zombies are scary?"
Song Ziyu shook his head blankly.
Afa said: "The most terrifying thing about these zombies is not that they can eat people, nor is it their sharp teeth and claws, but that they carry strong radiation!"
"Radiation cannot kill zombies, but it can accompany the zombies and infect humans in the entire subway station."
Afa sighed: "You see these humans mutated due to infection, most of them are caused by this."
Song Ziyu suddenly realized what he said.
"So, building a barrier to resist zombies is not as simple as you think. If it is close to a subway station, ordinary people will suffer greater radiation damage. In this environment, let alone building defense projects, it will not be sustainable even if you stay for a long time. Life."
Afa explained.
"I...seem to understand!"
Song Ziyu sighed.
I have made an empirical mistake, that is, I always like to think about other people's affairs from my own perspective, and point fingers at others from the perspective of nothingness.
This is like a group of people who are struggling to get a primary school degree but want to talk nonsense about the scientists who built the space shuttle atomic bomb.
It's so stupid not to realize it.
"Let's continue on our way, we'll be arriving at the West Rail District soon," Ah Fa said.
So the two of them hacked and slashed their way towards the West Rail District.
…
Wei Kai and his men stayed on the 2741 subway section, winning all the bullets in their hands.
The battle is too fierce!
I don’t know why, but there are so many zombies today!
"Give me a box of bullets! I need help!" Wei Kai shouted to his companions.
However, no one had time to respond to me!
Wei Kai looked around and saw his companions fighting bloody battles in the dim light.
The simple iron fence set up on the subway corridor was crumbling, and countless zombies were stretching out their heads and hands to scratch in the air. Some unlucky companions were even caught and gnawed by the zombies.
Wei Kai felt despair in his heart.
It doesn't matter if you die, but if the enemy breaks through this line of defense, they will enter the core area of the West Rail District Refuge.
There, hundreds of thousands of survivors will become the targets of zombie slaughter.
Behold I have a city in the last days.
