The words were clear and serious, and the tone was serious, "It's decided, I have only one way to choose from beginning to end." ”

Physician Cheng En looked at Peony, she nodded, took out a tube of potion from the pocket of her skirt and handed it to Cheng En; The potion was sealed in a transparent glass tube, which took on a white cloud and churned in the tube.

"This is the elixir we developed to unlock the gene," Cheng En introduced to Yan Qingcheng, and placed the glass tube horizontally in front of his eyes for him to observe carefully, "This tube is a dose of five people, a total of ten milligrams; We have carefully studied the dosage, and the limit that adults can tolerate is two milligrams, and it is absolutely not allowed to overdose; In the past, we have found many people like you who are genetically locked in, and the Wing Clan population was too small at that time to take a radical approach; We injected double the amount in an attempt to increase the probability of awakening, but only the mortality rate was increased, and the almost imperceptible increase in the probability of awakening was negligible compared to the cost it paid; After giving half of our lives, we finally got the data on the safe amount, but it was a pity for those who died in vain. ”

Speaking of this, Cheng En seemed to remember something, and he asked Peony, "Why did you take a brand new tube for me?" Didn't the last tube use up three-fifths? ”

"Grandpa Song said that the tube of medicine leaked when it was sealed and could not be used again."

"It's strange, this kind of precious potion is sealed by my own hands, how can it be wrong?"

"Grandpa Cheng, you work hard, and you work so hard every day, there will definitely be a hundred secrets." Peony hurriedly seized the opportunity to pat himself on the back.

"I haven't gotten to that level yet," Cheng En obviously didn't take this set, and continued to explain to Yan Qingcheng, "About three minutes after the injection, your body temperature will rise to more than 40 degrees, but you will be conscious; After 10 minutes, your breathing and heartbeat increase dramatically, and you can clearly feel the blood circulating throughout your body at high speed. After half an hour, the whole body tingles, and from this time onwards it is the hardest period, and it will last for four hours until you drain all your physical strength. After this period of time, your body will begin to change, and the wing bones will grow out of the spine and puncture your skin directly; At the same time, I will make an incision to remove your twelfth pair of ribs, because their presence will affect the development of the pterygium; It only takes about a week for your wingbones to fully develop, and then wait for the skin and feathers on the wingbones to grow together; We'll get you in a zero-gravity sterile ward, so you won't bleed as much as you need to know when your pterygoid bones develop, so don't worry. ”

"I was targeted because I was privately studying the bones of the Wing Clan, and I knew what would become of my body." Yan Qingcheng responded.

"Okay, let's get started."

Cheng En motioned for Yan Qingcheng to take off his shirt and lie on the operating table, while inserting the tube of medicine into the syringe of the robotic arm; He then secured a mechanical lock around Yan Qingcheng's waist and took a spray port and aimed it at his spine.

"I will apply a local anesthetic to your spine, which will make you lose the sensation of your lower limbs, don't be afraid."

"Hmm."

In the process of gradually losing sensation in the lower half of the body, Yan Qingcheng remembered those rumors on the operating table; It is said that after a patient is given a local anesthetic, certain unscrupulous doctors will lift their bodies and make them watch as they are cut open; In some cases, the patient's intestines are removed from the stomach and dangled in the air. Although these behaviors are not harmful to the patient, they are really scary; The patients who were tossed and turned had no choice but to endure in silence.

Probably the current doctor-patient relationship is strained by these unscrupulous doctors, Yan Qingcheng smiled silently.

Geriatric doctor Cheng En is obviously very responsible, and the peony who looked at him with a bad smile next to him is not necessarily, he remembered that yesterday in the underground hall, the girl threw his body like a rag doll, if she was allowed to knead it, nine lives would not be enough.

Cheng En took a control panel from the console next to the operating table and input the relevant data of the spinal injection; A fifth of the tube of potion on the robotic arm was drawn, and the thick needle popped out and stabbed down on Yan Qingcheng's spine.

He didn't feel it under local anesthesia, but looking at Peony's eyes that were smiling brighter and brighter, he knew that the injection had begun.

The injection process was completely mechanically manipulated, and Cheng En stared at Yan Qingcheng tightly on the side.

"Okay, no problem, that's it," about ten seconds passed, Cheng En watched the needle pull out of Yan Qingcheng's spine, and breathed a sigh of relief, he took the trauma patch prepared by Peony to seal the wound, untied the mechanical lock on Yan Qingcheng's waist, and helped him sit up from the operating table, "The spinal injection went very well, wait, no matter what happens in the future, don't be afraid, no one has ever had an accident at this dose." ”

"Okay." Yan Qingcheng's heart was beating fast, but he knew it was because he was too nervous.

Three minutes passed, and his temperature was stable.

Ten minutes passed, and he didn't feel the flow of blood.

Half an hour passed, and the power of the local anesthetic began to wane, but the stinging sensation that had been said to be good did not appear at all.

"This can't be, your presence is clear in my perception, you must be a natural wing clan!" Peony was a little excited, and said something he didn't understand.

"But this is a standard sign of failure, and those who have not reacted for more than half an hour have not been able to regrow their wings in the end." Cheng En frowned and pondered.

"Wait, maybe he has a special physique?"

Yan Qingcheng didn't interject when the two were talking, and he felt that after injecting the medicine, his body was much calmer.

Twelve hours had passed, and the storm outside had long since stopped, and it was already late at night, and the three people in the operating room had gloomy faces and the atmosphere was silent.

"Alas," Cheng En let out a long sigh and broke the silence, "I can confirm that I failed, Qingcheng, I'm sorry, I couldn't help." ”

"It's okay, didn't you say that even ordinary humans can survive?" Yan Qingcheng stood up and bowed deeply to the two, and walked out with a normal expression.

Seeing this, Peony wanted to follow, but Cheng En stopped her.

"Grandpa Cheng, he must be very uncomfortable now, let me go and take a look, what if he suddenly can't think about it?"

"Don't go, when a man is hurt, he only wants to lick his wounds alone, and you go to comfort him and only make him more uncomfortable; Besides, he is a determined child and will not fail to think about it. Cheng En explained slowly, and then began to tidy up the operating room, putting away the tube of medicine and handing it to Peony.

Yan Qingcheng in the corridor slowly walked forward step by step, and he felt that his heart was gradually becoming cold.

He returned to the hospital room where he had slept overnight, collapsed on the bed, covered his face with his hands, and gritted his teeth hard.

"Still, failed? In the end, even the only way to go was not to go. ”
