"Replace the faulty part?"
"Mom will never have to worry again!" Hah!
"Who says it can't be replaced?"
Fang Er slapped his forehead, "Old Sun, replace it!"
Old Sun didn't quite catch on and looked at Fang Er doubtfully, "Replace what?"
"Replace the kidneys!"
"Replace Ashina Bobi's kidneys!"
Sun Simiao: "..."
"Can that thing even be replaced?"
"It definitely can be replaced! Either way, he's facing certain death. Why not try for a chance?"
Fang Er's tone was firm, his eyes fixed on Sun Simiao.
"My young friend speaks with astonishing boldness. Putting aside whether it can be replaced, where would we even get kidneys to replace his?"
Old Sun looked at Fang Er in shock.
Fang Er pointed towards Shenyang, "The death row! The death row inmates in Shenyang city!"
Sun Simiao was silent for a long time, then shook his head, "My young friend, regardless of success, your actions would be against the natural order."
Fang Er stood up and paced in the ward.
"I know your concerns, Elder Sun. Doctors are meant to save lives. Asking you to do this indeed goes against the principles of medicine."
"But consider this from another perspective: Ashina's tribe has only recently surrendered. If Ashina Bobi were to die in Shenyang now, what would his tribesmen think when the news reaches them?"
"Would they not think I intentionally killed him?"
"If that caused a rebellion, how many more lives would be lost?"
"Sacrificing one to save a thousand, to save ten thousand, that's a worthwhile trade!"
"Besides, we don't necessarily need to replace both. Just one is enough."
"Replacing just one carries less risk than replacing both. As long as it's successful, a single kidney can save Ashina Bobi's life!"
"At most, the one who gives the kidney can be promised a lifetime of prosperity by Ashina Bobi."
"For a death row inmate, trading a kidney for a chance to live might not be such a bad deal."
Old Sun had never heard such reasoning. A kidney could save a life?
"Can someone else's kidney truly be transplanted onto Ashina Bobi?"
"My young friend, are you certain this is feasible?"
"It's definitely feasible!"
Fang Er patted his chest and guaranteed it.
"It can't just be anyone, can it?" Old Sun pressed further.
"No!" Fang Er shook his head. "Just like when Duke Yi Guo transfused blood, we must first confirm the blood type. Otherwise, the transplanted kidney might cause Ashina Bobi to die even faster."
*Hiss!* Old Sun gasped.
The conversation between the two was like a foreign language to the tribal leaders present.
"What in the world? Can things from a person's body be replaced?"
"My lord, use mine!"
At this moment, one of Ashina Bobi's personal guards volunteered.
"And me! As long as our Khan can be saved, take both my kidneys!"
"And me!"
"Count me in!"
"Take mine! It's just a kidney. What you eat is what you become, I'll eat more to replenish it!"
A group of guards stepped forward.
Fang Er was speechless. "What you eat is what you become" could replenish this?
"Ignorance is truly terrifying!"
He turned to the silent Old Sun and asked, "If Ashina Bobi doesn't have the transplant, how long can he last?"
"If I use potent medicine to stimulate his remaining vitality, I can guarantee him three days of life. After that, it's uncertain, entirely dependent on his fate."
"Three days. Such a short time."
"Elder Sun, try to sustain his life for now. Three days, though rushed, should be enough to make preparations."
He then looked at Su Feng by the door, "Go into the city and find Liu Dacheng. Bring all the death row inmates here!"
"Yes, my lord!"
Su Feng turned and left.
Seeing Fang Er ready to make arrangements, Sun Simiao could only nod in agreement.
Fang Er also got up and left.
Organ transplantation, even in later generations, was a highly complex surgery and could not be taken lightly.
The first priority was to set up a sterile operating room.
He called Zhao Gang and found a newly constructed side courtyard, tidying up one of the rooms.
A bed was brought in to serve as an operating table.
A circular disk with a diameter of one meter was hung from the ceiling.
Nine lamps were fixed onto it. Fang Er adjusted their angles until he was certain no shadows were cast beneath the lights.
After completing these arrangements, the entire operating room was disinfected twice more before being sealed, with strict orders for no one to enter or exit.
The operating room was ready, but surgical attire was also needed.
He took out several sets of camouflage uniforms from his spatial storage and handed them to Xing'er in the backyard, instructing her to wash them clean with alcohol.
Fang Er then turned and went to the workshop.
Surgical instruments were essential.
Various forceps, clamps, and scissors occupied the workshop's machinery for an entire day.
Although he hadn't handled these tools before, he had seen plenty of images online. Crafting them wasn't particularly difficult.
By evening, he appeared before Sun Simiao, carrying a set of forceps and scissors.
"Old Sun, these are a set of instruments I've fashioned for you."
Old Sun looked at the gleaming scissors and forceps, somewhat bewildered. "These are...?"
"You should know better than I do about the complexity of blood vessels within organs. If even one is connected incorrectly, it could lead to complete failure."
"To do a good job, one must first have sharp tools. Therefore, I've made these for you. See if they feel comfortable to use?"
After hearing his explanation, Sun Simiao couldn't help but mutter to himself, "How would I know if they're comfortable? I've never done this before!"
He took the instruments and examined them closely, but couldn't figure out how they were meant to be used.
Fang Er said to Su Mu, "Go outside and get some sheep."
Before long, Su Mu returned with a flock of sheep.
Old Sun didn't understand why sheep were needed and looked at Fang Er curiously.
Fang Er smiled and said, "Elder Sun, since there's still time, you can practice on these sheep first. No need for transplantation. Just remove their original organs and then stitch them up."
"They're just livestock. If they die, we can consider it an extra meal."
Old Sun's eyes lit up. "That's truly a good idea!"
"Very well. In that case, I shall give it a try!"
He took the sheep and went to the operating room. Su Mu was then instructed to fetch the dried camouflage uniforms from the backyard.
"Elder Sun, please wear these. I had these clothes treated with alcohol."
Sun Simiao nodded, his eyes full of approval.
"This young man is indeed thoroughly prepared."
Fang Er and Old Sun changed into camouflage uniforms, donned rubber gloves, and washed their hands with alcohol.
Su Mu, Su Feng, Liu Wu, and Ma Guocai followed suit.
They selected a robust ewe from the flock, and the six of them entered the operating room.
Fang Er switched on the ceiling lamps, illuminating the room brightly.
Sun Simiao had seen lamps in Fang Er's room before, but seeing so many here, a trace of bewilderment flashed in his eyes.
However, he didn't have the mood to dwell on it at that moment.
Su Mu and his men carried the ewe onto the operating table and secured it firmly.
Sun Simiao looked at the snow-white ewe and suddenly felt at a loss.
"My boy, what do we do next?"
Fang Er habitually reached to scratch his head, then remembered he had just disinfected his hands and lowered it, pointing at the ewe.
"Shave the fur, open the abdomen. As for which organ to cut, that's up to you, Elder."
"Let's do it!"
Old Sun spat out the word with emphasis.
It wasn't an expletive, but literally meant "Let's get started, let's work!"
