Zhu Yanyi smiled slightly. "The third needle of the 'Withered Wood Meets Spring' technique is the anesthesia needle."
"Anesthesia needle?" Old Yun looked at Zhu Yanyi, signaling her to continue.
Zhu Yanyi did not keep her guessing. "Actually, in ancient times, before Hua Tuo created the Mafeisan anesthetic, someone had already invented acupuncture anesthesia. This person was the legendary Medicine God, Azure Sovereign Qingdi. Whether she existed or not is debatable, but acupuncture anesthesia is a fact. It was lost due to the disappearance of many classical medical secrets, especially after the burning of books. Some people suspected and studied it, but no one succeeded. Martial artists remember that the human body has 'numb points.' If you press these points, a person cannot move. The same principle applies to acupuncture. The creator of the thirteen needles of 'Withered Wood Meets Spring' invented this anesthesia needle when creating the third one. Currently, only Grandpa Yao and I know this technique. Since Grandpa Yao must hold the scalpel, I must be the anesthesiologist. Does this count as volunteering myself?"
As she finished, Zhu Yanyi laughed. The cinnabar mole on her forehead looked particularly rosy and lively. She gave a playful smile, sticking out her tongue to show she was done. Old Yun pointed at her helplessly. "You little girl are becoming more mischievous. You seem calm usually, but only those who know you well see your playful side."
Zhu Yanyi stuck out her tongue shyly. "I am telling the truth. Besides, this is the answer you wanted, Grandpa Yun. Actually, Grandpa Du’s body is much stronger than yours was back then. Now, it is just a piece of shrapnel. Although its location is tricky, the problem is not too big. As long as we remove the shrapnel and rest for a while, she will be fine."
"You will handle the recovery," Old Yun said directly.
Zhu Yanyi pouted. "Why me? Grandpa Du is Grandpa Yao’s patient. Grandpa Yao should handle the recovery."
Old Yao coughed. "I am old. Making medicinal meals is too tiring. Ani, leave the post-operative care to you. Don’t worry. Tell your senior brother if you need any herbs."
Zhu Yanyi felt that Old Yao was doing this on purpose, but she did not refuse. She nodded. "Okay. After the surgery, I will take care of Grandpa Du’s recovery. But let’s agree first: whatever I make, you must eat. You cannot complain about the strong or weak taste of the medicine."
Old Du laughed. Perhaps because he had long served as a staff officer, he always had a faint air of elegance. "Rest assured. As long as it is good for my body, I will not refuse to take medicine."
Knowing she could not push it away, Zhu Yanyi shrugged and stayed silent. The post-operative matter was settled.
"When does Grandpa Du plan to have the surgery? I will prepare the operating room," Gu Jingtian asked.
Old Du paused slightly. "You should ask your master about the surgery. He is the lead surgeon. He decides."
Old Yao did not answer immediately. After a moment of thought, he spoke. "Although your body looks good, surgery requires the most vital energy. Therefore, you need to rest and recover for five days first. We will perform the surgery in five days. For this pre-operative recovery, Ani, let’s not trouble others. You will be responsible for this too."
