Zhu Yanyi stopped hiding the truth. "The toxicity of Mu Lingxi is exactly as I said. The effect is the same as what I told Yin Mei."
She paused, then continued, "But I added another herb called Tianya. It is very rare. I found it by chance. Tianya has a six-month hidden period. After six months, it releases an invisible scent. This scent lasts for ten years. There is no cure for it."
Zhu Yanyi smiled slightly. "Humans cannot smell this scent. But turtledoves can. Tianya is one of their favorite foods. So, we just need to catch a turtledove. It will lead us to the person."
Yan Aohan asked, "Will Tianya be discovered?"
"I don't know. Maybe," Zhu Yanyi replied. "The antidote for Tianya is Zhen poison. But if you take Zhen poison, the Tianya is cured, but the Zhen poison kills you. That is why I said there is no cure. To live, one must not take the antidote. Unless the person does not fear death. But do you think Yin Mei is brave enough to face death? I do not believe she has that courage."
Yan Aohan laughed and nodded. "You are right. Yin Mei is not a man who ignores death. Six months is enough time for us to prepare. After six months, we will go together to bring Elder Yao back."
"Good," Zhu Yanyi nodded. She trusted Elder Yao’s ability. Even if she was in their hands, she would not die. She would live well. After all, she had survived such hard times. The current difficulty was not that big.
When Zhu Yanyi went to see Elder Chun, she saw her drinking water. Elder Chun looked at her, seeming confused. She did not remember her. She looked at her carefully for a long time before speaking.
"I… have I… seen you?" His tongue was stiff, but his spirit was good.
Zhu Yanyi checked her pulse and smiled. "Grandpa Chun, I am Ani. Your youngest disciple. Your last disciple. You loved me very much."
"An… i." Elder Chun tilted his head. He seemed unable to remember such a person.
"It is okay, Grandpa Chun. Take your time. It is fine if you cannot remember," Zhu Yanyi sighed. She felt a bit sad, but as long as she was alive, it was good.
On the way home, Yan Aohan looked at Zhu Yanyi, who seemed worried. "Ani, what is wrong? If Grandpa Chun wakes up and sees you sad, he will be sad too."
Zhu Yanyi shook her head slightly. "I know Grandpa Chun is like this because he is missing one-tenth of his brain marrow. I am thinking how I can make up for that missing part."
Yan Aohan paused. He looked at her. "Ani, you are not planning to do something dangerous, are you?"
"No," Zhu Yanyi denied it quickly. "The only thing I want to do now is to refine the Nirvana Pill." She thought about the Fengchun, Tianzhi, and other herbs she had. She was calculating what herbs she still needed.
"Nirvana Pill?" Yan Aohan looked at her, confused.
Zhu Yanyi explained the use of the Nirvana Pill to him. Then she said slowly, "I am thinking, if I successfully refine the Nirvana Pill and give it to Grandpa Chun, can he use its effect to recover the lost one-tenth of his brain marrow?"
