Chapter 19: Retreat to the Immortal World

Lin Yi recognized what was stuck in the monster's neck at a glance.

That's An Chengdao's knife.

"Did you just use these two knives to kill the monster?" Lin Yi was a little surprised.

"You think too highly of me." Zhou Kao shook his head and said, "Most of the people living here are monsters. In order not to wake up other monsters, you must attack quickly and accurately. It is best to kill them with one blow."

"I can't kill this monster in an instant."

Looking towards the ground, this monster was killed before it even had time to show its true appearance.

If anyone could really do this, there was only one person Lin Yi could think of.

"An Chengdao?!"

There were subtle footsteps in the corridor, and then, An Chengdao walked in from the door with a cold face.

He was wearing an ill-fitting sweatshirt that looked like Zhou Kai's clothes.

He was carrying a bag specially used for knives on his back. He glanced down at the monster on the ground, and the two bone-splitting knives instantly flew out of the monster's neck and returned to the bag on An Chengdao's back.

"Why did you bring him here?" Lin asked in a low voice.

"Without bringing him here, do you think I can save you from the monster alone?" Zhou Kai replied.

"If you want to kill a monster in an instant, you must know the structure of the monster very well. He has killed many monsters and is a butcher himself. He is the only person I can think of."

Zhou Kai shrugged.

After seeing Lin Yi being taken away by the monster, Zhou Kai knew very well that he could not save Lin Yi with his own strength.

After thinking about it, Zhou Kai thought of An Chengdao on Sifang Mountain.

So, he hurriedly returned to Sifang Mountain, helped An Chengdao re-bandage his wound, and fed him medicine.

"You were right what you said before." Zhou Kai approached Lin Yi and said, "He is indeed more monster than monster."

"With such a serious injury, it stands to reason that I won't be able to move at all for three to five days."

"At the beginning, I had the attitude of treating a dead horse as a living horse, but he woke up the next day, as if nothing was wrong."

Zhou Kai originally thought that it would take a lot of words to get An Chengdao to rescue people, but he never thought that An Chengdao would agree immediately after hearing this.

"I remember you told me that you would be eaten by monsters on June 10th, so I hurried over here."

Zhou Kai's plan is simple. He knocks on the door first and distracts the monster by talking to it.

An Chengdao hid in the stairwell. After determining the location of the monster, he used his ability to control the bone splitting knife to kill the monster.

"One more thing, do you know why those monsters found us?" Zhou Kai asked.

Lin Yi shook his head. He had never been able to figure this out.

"Pheromones." Zhou Kai explained.

"These monsters leave pheromones on the humans they feed."

"Through these pheromones, they can pinpoint your location no matter where you go."

"Fortunately, only the owners can smell these pheromones. Now that all your owners are dead, you don't have to worry about these."

Hearing this, Lin Yi breathed a sigh of relief.

"Since you know this, why didn't you tell me earlier?" Lin Yi asked.

Zhou Kai pointed at An Chengdao with his chin and said, "He told me these on the way here."

"You're right, he knows these monsters better than we do."

He was very glad for his original decision. If he had abandoned An Chengdao and left directly, even if he did not return to the city, he would eventually be found by the monster because of the pheromones on his body.

Lin Yi turned back and glanced at An Chengdao. Perhaps because of excessive blood loss, his face was pale at this time, but even so, An Chengdao still looked fierce with a frown and a serious face.

Lin Yi felt that he should say thank you, but before he could say anything, An Chengdao grabbed the car key on the shoe cabinet and said, "The man has been rescued. Now follow me to the butcher shop."

"Going to the butcher's shop?" Lin Yi was stunned for a moment, "Why are we going to the butcher's shop? Do we want to escape with half a pig?"

Lin Yi glanced at Zhou Kai, only to see him looking equally confused.

"This is different from what we agreed." Zhou Kai said, "We agreed to return to Sifang Mountain immediately after rescuing people, and then escape from the city."

"You can't go anywhere without the key." An Chengdao said with a cold face.

"Key?" Lin Yi asked doubtfully, "What key?"

"The key to leaving this city." An Chengdao continued.

"This city is much more complicated than you think. Do you think you can escape from here by following Sifang Mountain? It's ridiculous."

"This city is a place similar to a breeding ground. Without a key, even if you climb over Sifang Mountain, you will end up with a dead end."

"Feeding farm?" Lin Yi was shocked, "What do you mean?"

"If you know this, do you know what these monsters are about?"

"Why are there monsters where we live? What is happening in this city?"

An Chengdao didn't answer. He looked outside the corridor and walked out: "Speak on the way."

Lin Yi and Zhou Kai hurriedly followed.

They came to the parking lot and found Lin Yi's father's car.

After getting in the car, An Chengdao drove to the butcher shop.

"Uncle An, can you tell us now?" Lin Yi couldn't wait to know what was going on.

"A few years ago, I opened a pig farm in the suburbs." An Chengdao began to tell his experience of discovering the monster. "The pigs raised in the pig farm will be taken to the butcher shop after slaughter."

"Everything was fine until three months ago, because the door of the pigpen was not closed properly, all the pigs ran away."

"The pig farm is very small. If I can't find these pigs, this year's work will be in vain. So, I started looking for these escaped pigs."

"I looked for a long time until I saw the bodies of these pigs."

"These pigs... were eaten by monsters?" Lin Yi asked.

An Chengdao shook his head and continued: "It's not a monster, but a special device on the edge of the city."

"If you don't have a key, you will die immediately once you try to leave the city."

"This is impossible!" Lin Yi felt a little absurd, "If people in this city can't leave, what about those who got into college?"

"You only saw them get into college, but have you seen them come back?" An Chengdao asked back.

Lin Yi was stunned for a moment, and he suddenly thought of the son of Grandma Liu upstairs.

Grandma Liu said that her son was working in another place, but Lin Yi had never seen his son come back, even during the Chinese New Year.

"Besides, I've said that this city is a place similar to a breeding farm. Humans are livestock being raised, and monsters are the owners of humans."

"In order to keep the livestock in the breeding farm continuous, this city has special routes to enter and exit, allowing monsters to trade livestock. But these places, humans can't pass at all."

Lin Yi understood that the special device on the edge of the city is equivalent to the electric grid surrounding the breeding farm.

Once livestock approach, they will be electrocuted.

To leave, you must go through the "front gate".

Monsters can tell who is a human, so humans without monsters can't leave through the "front gate" at all.

"How do you know this?" Lin Yi asked.

"Because, when I was looking for a pig, I found a skeleton. Next to the skeleton, there was-"

Before he finished speaking, Zhou Kai's face suddenly became very ugly.

He interrupted An Chengdao's words and said in a panic: "Oh no, we've been tricked!"
