As a colony, the PU-31 bookstore has a particularly diverse and all-encompassing collection of books of all ages and directions, old and new, and seems to have been collected from different places.

This time-space is far more accepting of parallel worlds than the time-space they are in. Judging from the number, there may be more than one colony similar to PU-31, but when Jiyu found that there were very few books covering this knowledge in the bookstore, it was possible to find The book "Mini World: PU-31" just now is still because of its conspicuous name. This shows that people are not new or valued in this aspect - of course, it does not rule out the possibility that those knowledge are stored in the cloud or network library.

However, fortunately, there are some gains.

Ji Yushi walked and read while walking, and asked Song Qinglan to help take down the books he needed.

During the rainy season, he wasn't bossy, and he didn't deliberately use the bruises on his wrists to bully others.

With such vengeance, don't know how to find a boyfriend.

Song Qinglan looked at Ji Yu's profile and angle. When she saw Ji Yu, she was focused and serious, like a small fan with eyelashes.

Maybe because it looks good.

Even if the sexual orientation is different, the aesthetics should be similar to the way they look at girls.

After a while, both of them held a high stack of books.

"Hurry up." Song Qinglan threw the book on the floor, "Pick up useful information and read it."

"I know." Ji Yushi said without looking up.

The sun is shining outside the bookstore, and the light is very good.

The sun shines into the bookstore and casts a golden patch, but no one feels the brilliance because of it.

Far away in the sky, there is a dormant black line.

Nearby, the zombies lying on the glass scratched "hoho".

"Pfft", a zombie was squeezed hard, a cloudy eyeball burst open on the glass, and the thick liquid slid down the glass.

Song Qinglan had a good tolerance, but she felt a little disgusting.

When they turned around, the three were looking at them with intriguing expressions, as if they were thinking about what happened after they were separated just now?

Song Qinglan squinted her black eyes, and the three of them immediately rushed up and divided the book.

"I'll take a look too!"

"Come here to help."

"Look for place names, characters, and anything related to darkness!"

Zhou Mingxuan opened a book and felt dizzy after just one glance. He stood up with a gun and said, "What, someone has to work shifts, I'll go to the second floor to keep an eye on it."

Li Chun: "Lao Zhou put it down and let me go!"

Tang Le pulled Li Chun back, he was not in the mood to play tricks, and his expression was very serious: "Look for it, in case you can find something useful."

Li Chun sat down obediently.

Song Qinglan thought for a while about what they had just discussed.

He went back to the counter of the bookstore and found the bookstore communicator that he hadn't found before.

If their wild conjecture is going in the right direction, then in the absence of a command center or even the need to hijack guardians of other time and space to get help, is the Vault of Heaven system itself controlling it? Task?

Song Qinglan had no conclusion.

This communicator is the same as the park management office's communicator, and it prompts several pieces of the same information.

[Welcome, guardian from Xingyuan 1456, welcome to PU-31. ]

[This transition has been locked and will be unlocked after the mission is successful. ]

[Mission Mode: Ouroboros. ]

[Task rules: death elimination. ]

[Quest objective: Dark Chaser. ]

Without a network, this information is sent one-way.

An idea flashed through Song Qinglan's mind, but out of the corner of his eye, he happened to spot a small square medicine box at the foot of the book.

He bent down and picked it up. The medicine box was clean and without any markings.

It is the monsoon season.

Hyperamnesia...

Song Qinglan looked at the teammates in the center of the bookstore.

Of the three, only one did not feel inconsistent with the bookstore environment during the monsoon.

Of course, it is impossible to forget this medicine box during the rainy season, but now I am busy looking for clues, and temporarily put the lost medicine box aside. Song Qinglan put the medicine box in her pocket, not wanting to disturb the other party's thoughts.

Unfortunately, there is no information related to "Dark Chaser" and "Black Wall" in the bookstore.

During the monsoon, he discovered a number of artificial cultivation projects used by PU-31, including but not limited to artificial soil, artificial water, etc. He flipped through a book: "The History of the Development of the PU Thermonuclear Fusion Experimental Reactor Program? Is it about energy sustainability?"

"What?" Li Chun was stunned.

"It's about energy," Ji Yushi said. "It mainly uses hydrogen and deuterium, and uses controllable devices to carry out nuclear fusion to release energy, which can be used for electricity and heat."

Everyone: "..."

Ji Yushi said: "That is to say, maybe the main energy of this colony comes from this kind of energy. Our era is also doing this research, but it is not as well developed as this era."

It doesn't have anything to do with the answers they're looking for.

Therefore, the book was put down during the rainy season.

After this conversation was interrupted, Song Qinglan picked up the half bottle of water on the bookshelf and handed it over, and wanted to give him the medicine box in her hand.

In the season of rain, there is a hint of cyan at the moment: "No need, thank you."

The bitter taste of beans still remained in his mouth, but he didn't want to touch this bottle of water.

Song Qinglan understood that this person still has a habit of cleanliness.

At this moment, when Ji Yushi looked out of the window, the expression on his face suddenly froze.

Everyone followed his gaze.

I saw a new wave of zombies gathered outside the floor-to-ceiling windows of the bookstore, layer by layer.

In the last row, there is a tallest zombie.

He was wearing a black combat uniform, with a large blood hole on his neck, exposed arteries and blood vessels, gray pupils, and a face exactly like Tang Le's.

"elder brother!!!"

Tang Le's eyes were blood red, and he shouted and got up and rushed over.

Everyone was shocked. This place was less than 20 kilometers away from the convenience store. They couldn't imagine how the sudden change of Tang Qi came here.

through a layer of glass.

Tang Le's tears were meandering. On the other end, Tang Qi opened his mouth numbly to reveal rotten gums. Facing the moving human, he was so excited that he wanted to tear him to pieces immediately.

"Ho! Ho!"

Zombies riot.

The bright light in the room suddenly turned black, and almost at the same time, Zhou Mingxuan's irritable voice came: "Come on! The black wall is coming!!!"

Everyone's heart sank suddenly.

Zhou Mingxuan has already rushed downstairs: "The second floor can see clearly!! I've been staring at it, it's just an instant! The speed is still accelerating!!"

Everyone looked at it, and the black wall that was far in the sky moved in the blink of an eye, as if it was coming to the front.

It quietly moved to a distance of only four or five kilometers outside the bookstore in the blink of an eye, and was flooding the city at an unimaginable and visible speed!

The black wall that covers the sky is like a cosmic black hole, everything that comes into contact with it disappears, and is submerged into the endless darkness. What is even more creepy is that the countless zombies in front of the black wall, the zombies scattered everywhere, seem to be naturally afraid of the power of darkness, and gather into a dense zombie tide rushing towards the light, and you can almost see the zombie tide. Dust and heat from running!

Tang Le was still standing in front of the floor-to-ceiling windows.

Zhou Mingxuan shouted, "Fuck!! Hurry up!"

Tang Le woke up like a dream.

The car stopped outside the bookstore, Song Qinglan grabbed Shenmian and walked out: "Everyone get in the car! Li Chun! Don't fucking pick it up!"

Under Li Chun's feet, the canned bones rolled to the ground.

The gunshots kept going, "Ho-ho" The zombies in the vicinity were attracted, and they all rushed over.

"boarding!!!"

"Hurry up!!"

The light in the bookstore dimmed again.

The dull sound of "Rumble" was the corpse tide that was chased by the black wall and fled in their direction.

While the corpse tide was engulfed by the black wall, new zombies gathered at the same time, and the sound was like bursts of muffled thunder, indicating the end of the day.

At this critical moment, he seemed to be guided. When Ji Yushi saw a book that had been knocked down in a panic in front of the bookshelf at the door, Song Qinglan had already grabbed his shoulder.

He turned his head abruptly, and in Song Qinglan's eyes he saw the anger he had never seen before: "Let's go!!"

Follow Song Qinglan to rush out of the bookstore, lift a gun to kill a zombie in Jiyu, and follow his teammates out in the bloody road!

"Bang bang bang bang!!!"

In the environment that quickly darkened, the gunfire was bright, and the sky was split in an instant, and the darkness was overwhelming.

The corpse is coming.

"what!!!"

In the darkness, don't know who's screaming came, but the zombies can't see anything clearly.

The car was blocked by the corpse tide. At the last second, Tang Le killed the zombies stuck in the car door and closed the car door. "Boom" The engine suddenly started, and he barely rushed out with powerful horsepower.

The zombies in front were knocked into the air, the windshield was blocked by rotten flesh and blood, and the wipers barely scraped. Zhou Mingxuan drove the car onto the road by feeling.

The darkness chased after him, and the scattered zombies behind him were swallowed up in the blink of an eye.

"Ho-"

In the back seat, Li Chun opened his mouth to bite.

In just a few seconds, there was a piece of flesh missing from his face, his skin was covered with cyan mesh veins, his pupils had completely turned gray, he had mutated!

Zhou Mingxuan saw this scene from the rearview mirror, the car suddenly lost control and almost hit Li Chun during the monsoon season!

Tang Le's voice changed: "Pure!"

The two held Li Chun down, the teammates' former voices and smiles were still in front of them, but they had become monsters who did not recognize their six relatives. How could Tang Le succeed!

The diamond bird in Ji Yushi's hand trembled involuntarily, only to hear Song Qinglan yelling in front of him: "Do it!!"

He closed his eyes.

"boom!"

The back seat was quiet again, and no one could see Li Chun in the dark.

The car rushed out a hundred meters in the blink of an eye, and suddenly there was a loud noise, and it rushed into the barbed wire in front of it, the windshield was all shattered, the car rolled over, and crashed to the ground for a distance of more than ten meters, completely shutting down!

The eardrums of everyone in the car tingled.

Zhou Mingxuan's head drooped, and his neck was bent at an incredible angle.

"Get out of the car!" Song Qinglan's voice was painful, almost roaring through gritted teeth, then she unbuckled her seat belt and fell to the ground, kicking open the car door.

After the car rolled over, the rear door was deformed.

Ji Yushi, Li Chun's body, and Tang Le were huddled together, Tang Le said, "Team Song!!"

Ji Yu experienced severe pain in his legs and his face was pale: "I can't open the car door!!"

Song Qinglan grabbed the edge of the broken car window, the glass shards plunged into his palm, and blood dripped on Ji Yushi's face, but he seemed unaware of the pain, so he gritted his teeth and forcefully removed the car door!

"Bang——" The car door was thrown open.

Song Qinglan stretched out her hand and Ji Yushi held it.

Hands clasped.

One was fair, the other was dripping with blood.

That big palm is tough and powerful, it belongs to the captain's responsibility, and it belongs to the friendship of the teammates.

Was pulled out of the carriage during the monsoon.

Next, Song Qinglan pulled out Tang Le.

The time was too late, the time was too fast, Tang Le landed in the first second, and the black wall was only a dozen meters away in the next second.

At that moment, everyone felt hopeless. They didn't care if there were zombies in front of them. They took out all the strength of their life and ran wildly. There was only one thought in their minds - run.

Ji Yushi felt that he had never run so fast in his life.

So fast that forgot about the pain in legs.

The wind rang in his ears, and the teammates beside him were the same as him, trying their best to survive in this time and space like him.

After running a few dozen meters away, a bad feeling arose in Ji Yushi's heart, and he turned back with Song Qinglan.

"Tangle!!"

Tang Le stopped.

He stood on the spot, a zombie was biting his neck, and blood flowed from his young body in an instant.

Tang Le moved his lips and said slowly, "Consultant Ji... We can't go back—"

This sentence is not finished.

Behind, darkness has arrived.

To drown this world, together with their survivors.
