"I don't know anything about side effects. I was just the assistant. Grandpa Yao did the real work." Zhu Yanyi passed the blame immediately. She knew how to play dumb.
Grandpa Yao nodded seriously at Zhu Yanyi's words. "Ani is right. You really don't know about side effects. You were just the assistant."
Grandpa Yao knew this meant Zhu Yanyi was taking a slight unfairness. But she also knew it was the safest choice. Zhu Yanyi was still too young.
Grandpa Yao understood. Zhu Yanyi understood. Gu Jingtian understood too. "Master is right. Ani was just an assistant today."
The three of them looked at each other, understanding silently. Then they all laughed. After laughing, Gu Jingtian asked Zhu Yanyi, "How much time do you need for this detoxification?"
Zhu Yanyi shook her head. "Not much time. Actually, 'Butterfly Change' is easy to cure. The herbs are very simple. The main thing is the acupuncture method. We need the thirteenth needle of 'Dead Wood Meets Spring'."
The last needle of 'Dead Wood Meets Spring' was the true essence. Since Zhu Yanyi wanted to teach this to Grandpa Yao, she would not hide anything. "But right now, only I can use it. Master has fast hands, but for the thirteenth needle against 'Butterfly Change', it is best to add inner power."
"Does the thirteenth needle of 'Dead Wood Meets Spring' really need inner power?" Grandpa Yao asked. He knew from medical books that if acupuncture used Qi, the effect would be many times stronger. But his generation had not passed down inner power. Did he really have to learn from Old Chun? If inner power was necessary, he would learn it even at eighty years old.
"No." Zhu Yanyi denied it immediately. "If you don't use the mutated technique, you don't need inner power. Even for early cancer, Grandpa Yao's thirteenth needle can ease the pain. But 'Butterfly Change' is a mutated germ. So it needs a mutated method."
Seeing Grandpa Yao and Gu Jingtian looked confused, she changed her words. "Let me say it this way. The thirteenth needle is magical. It can change into the needed acupuncture effect based on the sickness. But it needs help. For normal sickness, the thirteenth needle is fine. But for mutated or abnormal germs, you need inner power to help. Then it will change into the needle method the patient needs. That is the true 'Dead Wood Meets Spring'. Otherwise, it wouldn't be called that."
Zhu Yanyi explained in detail. Grandpa Yao and Gu Jingtian finally understood. Gu Jingtian said, "So, having inner power or not makes a difference for these thirteen needles."
"Theory says so." Zhu Yanyi nodded in agreement.
"How can we get inner power?" Gu Jingtian asked.
"Practice." Zhu Yanyi gave her two words naturally. "I found an inner power manual last time. It worked well for me. I gave it to Grandpa Chun. If you want to practice, go ask Grandpa Chun."
"Little Junior Sister." Gu Jingtian’s eyes moved. He smiled happily. "I don't believe you have no backup copy."
"Hehe." Zhu Yanyi looked up and laughed twice. "I do. But copying it by memory is troublesome. It is better if you go ask Grandpa Chun for a copy yourself."
