The Apocalypse Research Institute is located in the eastern suburbs of Qining City, surrounded by walls, because it is far away from the city, there are few zombies here, and even if there are, there are only a few of them, and they are captured alive by the Apocalypse personnel after wandering here, and used as a living resource for the development of the X virus vaccine.

"Lao Ling, aren't you afraid that these people will treat you as a guinea pig and lock you up in the laboratory for research inside and out?" In a room, Zhang Yifei said to Ling Xiu with some concern.

Ling Xiu chuckled and said, "Since you know this, don't talk about me being infected with the X virus. ”

"Spicy next door, how can I publicize this kind of thing everywhere." Zhang Yifei rolled his eyes and said very unpleasantly.

"That's it!"

"Damn, aren't you afraid that my cousin will accidentally say it? She doesn't have any city, she's as innocent as a blank sheet of paper. Zhang Yifei said.

This reminded Ling Xiu that Tang Xiaomo was too innocent and had no scheming, if he knew what the vaccine was, maybe he would tell him about his immunity to the X virus.

"She's with Chu Liyue now?"

"Yes, the men and women in this institute live separately, and she and Liyue MM are in the building opposite." Zhang Yifei raised his eyebrows and said.

Ling Xiu exhaled lightly, don't worry too much, Chu Liyue should be able to tell Tang Xiaomo about the stakes, as long as it is clear that things are not so simple, and it is related to his safety, Tang Xiaomo will definitely not talk nonsense.

"Lao Ling, to be honest, I really don't understand what you're doing here to this broken research institute? Even if you want to spend the night, you can find a place outside casually, so there's no need to run here, right? ”

Zhang Yifei was very disgusted with this place, because there were Chu Liyue's instructors here, and more importantly, Chu Liyue's attitude towards her instructor Blood Mist was not cold at all.

Ling Xiu smiled slightly, and suddenly asked, "Do you think Hao Jing can be trusted?" ”

Zhang Yifei was stunned for a moment, although he didn't know why Ling Xiu asked this question, he still nodded: "It should be okay, you are kind and compassionate, when you go to college, you will learn that you have a high fever and are lying in the hospital for infusion, she immediately rushed to see you, more concerned than your girlfriend Zhang Ruolan at the time." ”

Ling Xiu couldn't deny that if it weren't for Zhang Ruolan, he would have started a relationship with Hao Jing, she was indeed a good girl.

"Since you think she can be trusted, then I have nothing to worry about."

"What do you mean? You don't want to tell her about your immunity to the X-virus, do you? Zhang Yifei's eyes widened.

Ling Xiu nodded: "The reason why I came here is to see if I can unlock the secrets of my body, Hao Jing happens to be a member of the research institute, so this is an opportunity." ”

"Spicy next door, Lao Ling, you have to think clearly, what I'm talking about is that the university club can trust Hao Jing 100%, but it's been three years, and people will change. Following that group of crazy researchers, Hao Jing may also be assimilated into a madman, don't set yourself on fire. ”

"If I miss this opportunity, I'm afraid I'll never know what is going on with my body, and I won't know what awaits me in the end!"

Ling Xiu shook his head bitterly and smiled, "For so long, my heart is actually full of fear, I am afraid that I will never wake up after sleeping one day, I am afraid that I will never be able to change back into human form after turning into red-eyed appearance, and I am even more afraid that I will suddenly lose consciousness and sanity, forget all of you, and wander the streets aimlessly like a zombie." ”

To his own brother, he can remove all disguises.

Yes, after being scratched by D2 and infected with the X virus, Ling Xiu had been in fear since he became a half-human, half-corpse that could only feed on meat, because if he was an ordinary person's standard, he should be regarded as suffering from a strange and miscellaneous disease, and he was deeply afraid that he would suddenly go crazy and hurt the people close to him.

Zhang Yifei was stunned, then sighed, and said with a heavy heart: "No, there will never be such a day!" ”

Ling Xiu patted him on the shoulder, as if to comfort him, and as if to comfort himself.

"Knock knock~"

At this moment, there was a knock on the door.

"She should be here!" Ling Xiu smiled lightly, got up and walked towards the door.

******

The night was quiet, and the institute was quiet.

Occasionally, patrolling soldiers passed by, and searchlights swept around the institute like radar.

When meeting with Ling Xiu, Hao Jing did not wear the researcher's white coat anymore, but changed into a loose dress embellished with tulle. She has a kind of pure and beautiful beauty, thin curved eyebrows, light eyeliner, thin lips and bright teeth, and a pink neck like jade.

The two chatted about their experiences over the years, and then sat down on a stone bench.

Ling Xiu found that three years had not changed much for this girl, she was still the same kindness, the same intellectuality, and she had only one wish, that is, to successfully develop a vaccine against the X virus and restore the world to its original state.

"Do you have any results?" Ling Xiu asked.

Hao Jing shook his head: "The structure of that virus is something we have never seen before, and once infected, it will quickly attack the body's immune system, activate the body's defective genes, and turn people into man-eating monsters, flesh and blood become rotten, and bones become extremely brittle."

Because the structure is different from all viruses we know, our original method of cultivating antigens has failed, and we cannot develop a vaccine that immunizes the human body against the X virus. The only thing we've achieved so far is the development of an elixir that can delay the transformation of people into zombies. ”

"Just delayed? Can't terminate? ”

"Yes, it is irreversible to become a zombie after being infected with the X virus, it only takes one day for a normal person to become a zombie from infection, and if you inject our medicine, the time can be delayed to three days." Hao Jing said helplessly.

After hesitating for a moment, Ling Xiu finally explained to her that he was immune to the X virus.

After hearing this, Hao Jing was stunned for a long time before coming back to her senses: "Ling Xiu, you ...... Are you sure you're not kidding? ”

This is definitely shocking news, and if it is true, it will be too helpful for them to develop a vaccine and antidote against the X virus.

Ling Xiu's eyes were sincere and said, "Hao Jing, I'm here to ask you for help. ”

Hao Jing fell into a moment of astonishment, staring blankly at the man in front of her.

"Did you bring a blood collection tube?" Ling Xiu asked.

Hao Jing nodded, and then took out a vacuum blood collection tube from her satchel.

Without saying a word, Ling Xiu plunged the thin needle into his arm, and the red blood suddenly poured into the vacuum test tube.

Hand the test tube full of blood back to Hao Jing: "Help me analyze it, keep it secret for me, I'm afraid that your colleagues will be used as guinea pigs." With that, he turned and left.

"Wait!" Hao Jing hurriedly stopped him.

Ling Xiu turned his head and looked at her with an inquiring gaze.

"Aren't you afraid of me telling you?" Hao Jing pursed her red lips and said.

Ling Xiu asked rhetorically, "Will you?" ”

Hao Jing was stunned, then smiled lightly, and said with a hint of resentment: "You are still so confident." ”

Ling Xiu shook his head: "Because I trust you!" ”

One of his goals is to seek answers for himself, and the other is to hope that the Apocalypse Research Institute can successfully develop a vaccine or antidote against the X virus and restore the world to its original state.

Of course, he believed that Hao Jing would definitely keep it secret for him during this time, and he trusted Hao Jing as much as he trusted Zhang Yifei.
