Zhu Yanyi did not know what Grandpa Yao was thinking. She simply nodded.
"Killing arrays drain a person’s life force and energy to take their life," she explained. "Medicine arrays are the opposite. They use herbs to wake up fading life force and help the body recover. Most importantly, if a medicine array is set up well, it can fight against killing arrays. Of course, it is best if those people do not plot against us. But if they try to set a killing array inside someone who already has a medicine array, their chance of success is zero."
Grandpa Yao’s eyes lit up. "So, if a person has a medicine array inside them, they do not need to fear killing arrays?"
"In theory, yes," Zhu Yanyi said calmly. "But not everyone is suitable for a medicine array."
Grandpa Yao blinked, surprised. "Why do you say that? Does this mean medicine arrays cannot be used by everyone? It seems my earlier idea will not work."
Zhu Yanyi paused for a moment before continuing. "Medicine arrays do more than just boost immunity or restore the body to its best state. More importantly, if used well, they can awaken different abilities in the human body."
"Different abilities?" Grandpa Yao thought for a moment. "You mean using medicine to awaken a person’s hidden potential?"
"Yes," Zhu Yanyi nodded. Her eyes looked deep and mysterious. "Normally, people use the left side of their brain for thinking. The right side is mostly closed. So-called geniuses are just people whose right brain is slightly awakened. Medicine arrays can stimulate certain consciousness in the right brain. This gives people abilities different from normal humans. For example, some might see things miles away. Some might hear sounds from far away without any tools. Some might read minds. Some might see through objects. Some might move very fast. Anything is possible. That is why I usually do not support putting medicine arrays inside people. Medicine arrays are good, but human hearts change easily. If someone uses these powers to harm the world, it would be terrifying."
Grandpa Yao and Gu Jingtian gasped. If medicine arrays really had such effects, they indeed needed to be used with caution. Grandpa Yao thought for a moment and asked, "Do you still plan to use it on Zhao Guangzong?"
Compared to protecting her disciple, Grandpa Yao cared less about the patient. She was willing to give up the patient’s treatment if it meant keeping Zhu Yanyi safe, even if it made her feel guilty.
Zhu Yanyi smiled. She understood Grandpa Yao’s worry and felt warm inside. "Grandpa Yao, Senior Brother Zhao is Grandpa Chun’s eldest disciple. I trust Grandpa Chun. Also, when I use the medicine array, I will secretly add a layer of hypnosis. If no special abilities are awakened, it is fine. If special abilities do appear, she will not suspect me. She will only think it is a lucky side effect from the accident."
Grandpa Yao breathed a sigh of relief. "Then I can rest assured."
As Zhu Yanyi said, Grandpa Yao trusted Grandpa Chun’s judgment. In fact, these old friends trusted each other’s disciples. Among them, Grandpa Yao had the most disciples, including Zhu Yanyi, totaling six. Grandpa Chun had the most students, but her true disciples, including Zhu Yanyi, were only four. Therefore, these elders were very strict in choosing disciples. They looked for both good talent and good character.
