The breath in the cabin finally calmed down after a long time.

Lu An looked at Su Ruyu, who was soaked in sweat next to him, and didn't know how to say the feeling in his heart, he stared blankly at the bulkhead above his head, and after a long time his heartbeat calmed down, he asked, "Why?" ”

Su Ruyu blinked and replied, "No, didn't I say it before, I don't want to die and there are some things that I have never done." ”

Lu An smiled silently and said, "Yes, what you said is also right." But I'm always a little frustrated, I thought you had a crush on me. ”

Su Ruyu leaned sideways and propped up her arms, looked at Lu An obliquely: "Of course, it's because of you, otherwise why do you think I was so active just now, I'm such a casual person?" ”

Lu An smiled, raised his head and kissed her cheek, and then said pityingly: "But in this way, I don't want you to leave me anymore, I even greedily want to go on like this with you forever, and it will be good for a long time." ”

Su Ruyu looked down at Lu An's face, looked at the **** hair in front of his forehead, and said with a smile: "Your mouth is really sweet, and you are really a greedy little ghost!" ”

"Hmph, I'm not a little ghost."

After hearing this, Su Ruyu smiled, then leaned her head on Lu An's shoulder, and continued to smile: "Yes, yes, you are a majestic man, okay?" ”

Lu An hugged Su Ruyu tightly with his backhand, and after the two sweat-soaked people stuck together sticky and greasy, he sighed: "I really hope you can live well, if only the two of us could live!" ”

Su Ruyu poked his chest lightly and said softly, "Anyway, there's still a month, isn't it?" Let's talk about it then, we're still alive now, aren't we? Just take care of the moment. ”

Lu An smiled bitterly: "Yes, I'm even a little reluctant to let you lie in the dormant compartment coldly now, just imagine that I can hold you all the time like this." ”

"Hmm." Su Ruyu adjusted her head, leaned more comfortably on his shoulder, and snorted lazily.

Lu An turned his head mischievously, hugged Su Ruyu tightly and began to blow into her ears, making Su Ruyu itch and tremble but couldn't break free.

Su Ruyu had no choice but to stretch out her fingers, poke him under the ribs hard, and then said angrily: "Don't make trouble." ”

After the two of them laughed for a long time, Lu An stopped, put his arm around Su Ruyu's waist and asked, "By the way, I haven't asked yet, haven't I used PTDX-89752 before?" I've also learned before, isn't this potion very difficult to wake up? ”

After Su Ruyu said "um", she replied, "Of course it is." ”

"Then how could I ......?"

"If it was before, after using PTDX-89752, people could only slowly wake up after the concentration of the drug in the blood dropped to a certain level, but later this drug has been studied in depth, in fact, it may not be the case."

After rubbing Su Ruyu's wet hair, Lu An asked, "Could it be that there are other discoveries?" ”

"Hmm. As I said before, this potion is actually a type of medicine left over from before the era, and this potion is said to have been used to cure diseases at all a long time ago, well, don't mess around! ”

"Oh?" Lu An continued to blow and asked, "What is that for?" ”

"It's used to strengthen the human body." Su Ruyu poked him under the ribs and replied: "It is said that at that time, people began to be injected with this medicine before they were born, and most people carried this kind of intelligent nano terminal in their bodies for the rest of their lives, but then they ......."

Lu An raised his eyebrows, remembered what Su Ruyu had said before, and asked in surprise: "The so-called world catastrophe happened later?" ”

"Well, it should be the second world catastrophe, and the mentor said that the loss of the entire human world in this 'plague' is said to be even more heavy than the first time. After all, the first time there seemed to be no evidence that too many people had died, but the second time, the population of the human world had plummeted by 60 percent. ”

"Sixty percent?!" Lu An's eyes widened.

"That's right, the mentor said that the number of humans at that time didn't have to be as small as it is now."

"Isn't that nearly six billion dead?"

"Hmm."

Lu An turned Su Ruyu's face over, faced him, and asked, "Is it because of the plague caused by the so-called smart nano terminal?" Are they out of control? ”

"Hmm." Su Ruyu felt Lu An tremble, and then laughed in a low voice: "You are really a coward, PTDX-89752 in your body is not such a powerful thing, it can't be called intelligent at all, and I have filtered your blood several times, and the concentration of PTDX-89752 is already negligibly low, otherwise how would you come to your senses?" ”

Lu An breathed a sigh of relief, lowered his head and kissed the tip of Su Ruyu's slightly sweaty nose, and said with a smile: "Then you were deliberately scaring me just now?" ”

Su Ruyu wrinkled her nose and said, "So what?" ”

Lu An blew in her ear: "If yes, I will punish you!" ”

He had already discovered that after Su Ruyu's ears were gently blown, her whole body trembled uncontrollably.

After Su Ruyu smiled softly and weakly, he asked again: "Then why couldn't Anna use this method at that time?" She can also filter her blood until PTDX-89752 is completely gone. ”

Su Ruyu snorted, glared at him, and said angrily: "You really don't forget your sister all the time." ”

"She's my sister."

"Is it just my sister?" Su Ruyu poked him under the ribs and asked through gritted teeth.

Lu An had no choice but to lower his head and whisper in her ear for a long time before letting her let go of her fingers.

"Hmph, your sister must have been injected with an overdose of PTDX-89752 at that time, not to mention, and she must have been asleep for a long time. Moreover, didn't you say that your sister had a gap of two years from the time she entered your house to the time she became ill. Presumably, she had already undergone similar treatment when she was rescued, and her blood was repeatedly dialyzed, so she was able to stay safe for two years. ”

"Then why ......"

"Why did you get sick again?" Su Ruyu pouted and replied, "You are really chasing after you!" Hum! By the time she was rescued, PTDX-89752 must have been more than just in the bloodstream, it had reached the point where it had entered the bone marrow, tissue fluid, and even cells throughout the body, and according to your account, she was so frequent that even the brain was not spared. ”

"But, isn't it already very low?"

At this time, Su Ruyu remembered that the girl she had never met and had to endure the ravages of PTDX-89752 in her body for many years, and some pity rose in her heart, and she sighed softly and said, "However, PTDX-89752 will multiply itself." ”

"Self-proliferating?"

"Well, just like the renewal metabolism of human cells, or more like a virus that reproduces itself, a drug like PTDX-8975 will continue to multiply itself in the human body. Anna later became ill, presumably because PTDX-89752, which had previously entered the cells of the whole body, proliferated to a certain concentration, causing her body's physiological circulation to collapse directly, so she developed the symptoms of suspended animation. ”

"So, the interval between onset is getting shorter and shorter?"

"Yes, hemodialysis can only clear a very small part of PTDX-89752, and the concentration of PTDX-89752 in the cells in her body is getting higher and higher, and it is spreading to replenish the part that has been removed, so ......"

Lu An was silent for a moment before he replied, "I can now imagine why the plague before the epoch was called a world catastrophe, and why the human population has plummeted by sixty percent. ”

"Hmm." Su Ruyu gently poked Lu An's chest with a sideways face, "However, your sister has injected a large dose of PTDX-89752 from the beginning, so this situation is almost unavoidable. You're different, but you don't have to worry about that. ”

"Hehe, we don't really have to worry about that." After Lu An smiled bitterly, he lowered his head and kissed, "But, why?" ”

"Because, with the dose and time you are exposed to, the concentration of PTDX-89752 in your body will self-proliferate to the level of the disease, I am afraid it will be two hundred years later."

"Huh?" Lu An suddenly cried and laughed, "Two hundred years? It seems that I really don't have to worry, we can't even manage it in a month now. ”

Su Ruyu leaned on his shoulder and said a lazy "um".

"However, since PTDX-89752 has such a fatal problem, those people in the logistics department are really damn it, and they dare to ......"

Su Ruyu gently slid her fingers on Lu An's belly, and said casually: "No, this potion was originally developed by the War Equipment Command, and only they have these prehistoric dangerous items." Moreover, the bionic laboratory of the Lower Military Police Command, where my mentor and I are located, was actually subordinate to the War Equipment Command at the earliest, of course, there was no such command at that time, it seems to be subordinate to the Joint Space Guard, well, it's called the Reserve Device Research Department. Later, when the gendarmerie was formed, it became independent from there, and you must have heard of the reputation of the bionic laboratory, so you can guess how dangerous the War Equipment Command is. ”

After listening to Su Ruyu's words, Lu An frowned and said, "Such a dangerous thing, do they really dare to use it on a large scale so casually?" ”

"Well, your sister Anna is also in a special situation. If it's normal, you can understand how cheap and efficient this emergency sedative is, and how perfect it is to be able to self-sustain the concentration ——,of the agent. As for the sequelae, they are nothing compared to this cheap and efficient. Besides, who would have thought that such a large-scale war would break out at that time? If it is used for emergency rescue on weekdays, do you think it is very cost-effective? ”

Lu An frowned, although he didn't want to admit it in his heart, but he belonged to the military system, and he also understood the choice of the War Equipment Command, well, it should be said that it was the choice of the Reserve Device Research Department. Perhaps, it was only for some very urgent situation that they developed the PTDX-89752.

But who could have foreseen the last war nearly 100 years ago? War has changed everything, turning all good into malice, all good into ugly, and all hope into despair.

Isn't my sister Anna and herself extremely desperate for the future?

"Well, the way you look frowning is ugly."

Su Ruyu's fingers slid down slightly, clenched Lu An, and then said with a smile: "You're really young!" ”

Hehe, too, I don't dare to hope even a month later, what else is there to talk about despair or despair?!

Lu An grabbed Su Ruyu's waist arm and threw her upside down and put it on his chest.

"yes, I'm so young!"
