As a site for studying Black Pool, the institute is heavily guarded. Although there are no soldiers on guard now, those facilities are still operating.

Xia Yi and Jiang Ying climbed over the wall and were stopped by the gate.

The door has an electronic door lock. Even if the little fur ball sneaks in, there is no way to unlock it.

"Only an ID card can open this door. My ID card was taken away before the virus broke out." Jiang Ying looked at the door in embarrassment, "Let's go to the guard room first."

"No need." Xia Yi replied.

Jiang Ying turned her head and saw Xia Yi knocking down a zombie in military uniform and getting the ID card from its pocket.

beep

Xia Yi swiped the card and the door opened.

"Ah this..." Jiang Ying was stunned for a while. She was still using the same logic as before the apocalypse. She wanted to go to the guard room to steal it without an ID card. If she didn't react, she could get it from the zombies.

Entering the research institute, she drew inferences, asked the researcher zombie to touch the card, opened the corridor door all the way, and used the elevator to reach the underground.

"This is it." Standing in front of the last door, Jiang Ying looked solemn.

The two opened the door, and the first thing they saw was a large cave space, and then a wide pool. The pool was filled with black mucus, and the mucus was gurgling.

This is the Black Pool. Xia Yi stared at the dark pool surface and felt uncomfortable in his heart. The pure black, abnormally surging mucus made him feel horrified just looking at it.

The black water seemed to sense Xia Yi and the two of them, flowing towards their feet. Xia Yi pulled his girlfriend back to the door.

"No, how is that possible!" Jiang Ying looked at Hei Chi in disbelief.

"What's wrong?" Xia Yi asked.

Jiang Ying let go of Xia Yi's hand, walked to the edge of the pool and turned around, her eyes filled with astonishment.

She told Xia Yi: "Although I have never seen the water in the pool, I have heard from a colleague that she said the water in the pool is only one meter wide."

Xia Yi looked at the black pool. It was at least ten meters wide.

"If the Black Pond can grow, it's impossible for me not to hear the news." Jiang Ying bit her lip, the size of the Black Pond was not scientific.

Xia Yi had long since lost respect for science. He said: "Maybe it was after the zombie virus broke out that the pool began to expand."

"How could the virus outbreak be related to the size of Blackpool!" Jiang Ying could not understand this scientifically. The virus came from Blackpool, but there is no saying that the expansion of the virus will make the source of the virus larger?

"You can disassemble and assemble your brain, so you should be bolder in your speculations." Xia Yi put his arm around her waist and persuaded her not to use her current superficial scientific knowledge to apply it to the real world.

Jiang Ying took a deep breath and put down Hei Chi's question.

Xia Yi looked at the water in the pool: "Regardless of the scientific principles, think about whether you can find a way to improve human survival through this black pool."

He looked at his girlfriend: "Take a look."

Jiang Ying closed her eyes, and connected to the black pool like the consciousness that controlled the zombies.

If the consciousness of the zombies is an empty small USB flash drive, then Blackpool's consciousness is a large hard drive filled with data. When the connection is successful, the data inside rushes into Jiang Ying's brain.

Seeing his girlfriend's body falling backward, Xia Yi hurriedly hugged her.

"What's wrong?" Xia Yi could feel Jiang Ying's body shaking slightly.

What came from Hei Chi's consciousness was surging malice. Jiang Ying seemed to have fallen into boundless darkness, loneliness, pain, fear, resentment and other negative emotions, washing over her brain.

After lying on Xia Yi's shoulder for five minutes to adjust, Jiang Ying regained her composure.

She let go of Xia Yi's hand and shook her head: "I can't affect this thing, here..."

She wanted to find a suitable adjective to sum up the feeling that Blackpool made him feel, but she couldn't find it at the moment.

At this time, Xia Yi felt something move in his pocket. He put his hand into his pocket and took out a pen.

Xia Yi almost forgot about this pen. The last time he saw the pen move, it reminded him to rescue the survivors.

This time, the pen did not point in any direction, but trembled in place.

Xia Yi thought for a moment, stretched out his hand in front of the pen, stroked the tip of the pen on his palm, and wrote two words: "Despair."

Xia Yi and Jiang Ying looked at each other.

"What does this mean?" Jiang Ying asked.

"We are talking about the black pool, and we should be talking about this pool." Xia Yi looked at the black slime.

He thought to himself that before the pen pointed at the survivors, according to his understanding, it was because the survivors were in a desperate situation and faced despair. Now it seems that his guess is not wrong.

Is this black pool growing by absorbing despair?

"Cryer", the pen wrote these three words again.

"Is the cryer the embodiment of despair?" Xia Yi thought of the mournful cry of the cryer.

The pen didn't answer. It moved again, this time turning, and it turned to Xia Yi's rear.

"Let's go and take a look." Xia Yi and Jiang Ying followed the guidance and walked through the corridor full of zombies until they arrived at the place.

Opening the door, they saw a cryer.

The pen actually pointed directly at the cryer?

"Isn't this one pointing to the survivors, and now it's pointing to the cryers?" Jiang Ying was equally surprised.

"Anyway, let's settle it first." Xia Yi said.

Just as he was about to call the little furball, Jiang Ying jumped over, kicked the cryer, and tore off its head.

The piercing cry of the cryer echoed, and the little fur ball took out the black mist, threw away the crying head, and left the research institute with his parents.

The pen pointed in another direction.

Following the guidance, Xia Yi found a cryer again. It seems that this item has now become a cryer sensor.

The Cryer can transform into a mother body, allowing ordinary zombies to evolve. Eliminating the Cryer will block the way for zombies to evolve again, which is very important for survivors in the city.

For the sake of peace in the city, Xia Yi and Jiang Ying worked overtime.

…

One week later.

Xia Yi and Jiang Ying followed the guidance and came to an old community.

The community is not big, with more than 20 buildings in total. The walls of the buildings are mottled, and there are many zombies shaking on the road.

In one of the houses on the sixth floor, a thin middle-aged man was lying on the bed. He was not asleep and had no expression on his face. He was just looking at the roof.

As time passed, the sunlight outside the window slowly moved and shone on his face, making his cheeks move.

He sat up, put his bare feet on the floor, and walked to the kitchen. When he opened the refrigerator, there was finally an expression on his face, which was surprise.

There isn't any food in the refrigerator.

Yes, he ate all the food two days ago.

After closing the refrigerator door, he glanced at the medicine bottle by the sink and walked to the balcony.

Downstairs, seven zombies stood sluggishly.

He suddenly smiled. The expressions of these zombies were actually the same as what he saw in the mirror in the morning.

After laughing, he opened the window and leaned out.

it's over.

"Wait!" Xia Yi entered the house, saw this scene, and hurriedly stopped him.

The man turned his head and looked at Xia Yi. There was no surprise in his eyes that the other survivors saw his companion. He turned back and continued to lean out.

"Let's take a look at the goods first, don't leave in a hurry." Xia Yi added.

He looked at the middle-aged man and wondered why the pen pointed at the cryer suddenly pointed at the survivor.

The man hesitated for two seconds and asked: "What kind of goods?"

"There are snacks, snacks and staple food." Xia Yi opened the zipper of his satchel. When killing the corpses, he would also help the survivors.

"Do you have any wine?" the middle-aged man asked.

Is this going to tell a story?
