Let's walk together for the rest of our lives. If the host says to leave, she will leave.

"But I can't treat this world as a novel." Cheng Mu took a deep breath, "Gu Ling, take a good look at this world. I'm leaving first, good night."

Cheng Mu closed the door and left. Gu Ling walked to the window and opened the curtains. The night that was usually brightly lit was now empty, and one could vaguely hear the roar of zombies coming from afar.

"Zhou Paopi, I don't understand. This is a world made up of fiction, isn't it?"

The system's eggshell body twisted and sat on Gu Ling's head, with the same relaxed tone as always: "It's okay, you will understand it later, I will accompany you!"

As Gu Ling has come this far, his feelings have grown from nothing to something, and among millions of small worlds, only the system remains consistent.

Gu Ling smiled: "Shouldn't you explain it to me?"

The system looked out the window and seemed to see the figure of someone in a distant time again: "Some things can only be understood after experiencing them yourself."

Gu Ling's feelings grew from nothing to something, and the system's jealousy disappeared from something to nothing. Some things can only be understood after experiencing them yourself.

……

Although he knew that the abnormality of this world was caused by the world origin dropped from other worlds, Gu Ling still didn't know why Cheng Mu came to the book, and what was the relationship between the world origin and the original owner.

After much consideration, Gu Ling decided to stay with Cheng Mu.

Seeing that Cheng Mu and Gu Ling were familiar with each other, An He originally planned to let Cheng Mu speak well of Guangming Base in front of Gu Ling so as to add another general to the base.

But I didn't expect that the two people who had such a good understanding the day before, like fellow villagers meeting each other with tears in their eyes, would become as if "we are not familiar with each other" today.

Although Cheng Mu was still smiling and chatting with everyone, there was no smile in his eyes, and it was obvious that something was wrong.

Gu Ling didn't talk to Cheng Mu either. Instead, he stayed beside An He and seemed very curious about her.

Finally, after Gu Ling asked countless questions, An He couldn't stand it anymore: "Gu Ling, you asked me so many questions, it's my turn to ask you, right?"

Gu Ling shut up and nodded, and An He asked, "What is your special ability?"

"Uh... strengthening of physical fitness?" Strengthening the original owner's physical fitness is an inherent ability of Gu Ling's demonic power.

An He: “…” Yes, it is, and no, it is not. What’s with this questioning tone?

An He continued to ask: "Do you want to join a base?"

"Okay, I'll join you." The hero and heroine of the novel are both in the Guangming Base, so of course Gu Ling has to follow them closely.

An He was so amused by Gu Ling's answer that she asked the last question: "Did you have a fight with Cheng Mu?"

Hearing this, Cheng Mu, who had been secretly observing the two of them, withdrew his gaze, but his ears pricked up quietly.

Gu Ling's answer was not so quick this time. She paused and said, "No, we just have some different ideas."

An He did not ask what concept involved privacy.

The rest of the journey was relatively smooth, and all the zombies they encountered were dealt with one by one. Soon, the team arrived at their destination - the central building of Heng City.

The Central Building is the most prosperous commercial center in Heng City, with a daily traffic of up to millions of people. It is now also the place with the most zombies.

Cheng Mu looked at the dark mass of zombies in front of him and knew that he was on a pirate ship: "Captain, now that we are here, you should at least tell us what the mission is, right?"

"There is an underground laboratory in the central building. It contains a wealth of experimental resources. Dr. Zheng hopes that we can bring back as many of these things as possible."

Most importantly, this is the origin of the apocalypse, and the first version of the zombie virus serum is likely to be inside.

An He did not tell anyone the news. Before leaving, Dr. Zheng specifically reminded her that the fewer people who knew about this, the better, in order to prevent someone with ulterior motives from deliberately destroying the serum.

Hearing this, Gu Ling's face looked strange, as if she knew which plot this was about.

The laboratory in the central building was established by a group of enthusiastic scientists to study the mysteries of the human body. The laboratory transports experimental materials through a huge underground network and conducts human experiments in the laboratory.

After several generations of hard work, the laboratory developed a special drug that can enhance the human body.

After taking it, the human body becomes immortal, but the experiment goes wrong and they create a group of mindless monsters - zombies.

The experiment was not a complete failure. The test subjects who took the special medicine all turned into zombies, but the people who were bitten by the first generation of zombies underwent mutations. Some of them turned into zombies, while others turned into people with special powers.

Dr. Zheng is one of that group of crazy scientists, but it is obvious that An He does not know this. Instead, she regards Dr. Zheng as a life-saving straw for mankind.

The most important thing is that this plot only exists in Gu Ling's outline, and she has not written it yet.

The team continued to move forward. Cheng Mu slowly approached Gu Ling and whispered, "What do you know?"

After An He finished speaking, the change in Gu Ling's expression in that instant really made Cheng Mu panic.

Gu Ling quietly took the crystal in his hand and answered Cheng Mu's question in his heart.

The crystal was useless in Cheng Mu's hands, so after the two met, Cheng Mu gave the crystal to Gu Ling.

After listening to Gu Ling's words, Cheng Mu asked: "What will happen next?"

Gu Ling's eyes wandered: "There are no details. The general trend is that the team suffered heavy casualties, but still successfully completed the mission. After Dr. Zheng obtained the serum, he created the Zombie King."

Zombie King, full level zombie.

Cheng Mu could easily guess how the base would resist the zombie king in the end. As the male protagonist whose strength increases every time he dies, if he doesn't take the lead at this time, who will?

Cheng Mu didn't say anything, but the thunder in his hand became more lethal.

The crowd cleared a path into the building. An He went straight to the basement, found a storage room and went in.

After a while of searching, everyone found the password door and violently demolished it, advancing all the way inside and successfully entering the underground laboratory.

Human tissues soaked in formalin can be seen everywhere in the laboratory, as well as some semi-finished products that are between humans and zombies. What you see can be described as hell on earth.

The team members began to move the items according to the list given by An He, and some of them were responsible for guarding and vigilance.

Gu Ling followed An He into a big door. As soon as they stopped, the door suddenly opened automatically. The two of them dodged the guards and heard a voice coming from inside.

"Are you here to save us?"

It’s not surprising to see humans, but what’s surprising is that there are humans in a human laboratory surrounded by zombies?

The abnormality here attracted the attention of others. They slowly approached and saw more than a dozen neatly dressed, ruddy-faced humans inside, ranging in age from a few years old to over 30 years old.

Are they those mad scientists?

An He said with a cold face: "Who are you?"

Behind her, Gu Ling and others were already ready to attack.
