Zhu Yanyi began refining pills and medicines non-stop. Infiltrating the Evil Demons’ territory was dangerous, especially since most of them were high-level. To be safe, she prepared absolute-grade poisons, not the ordinary versions used daily.
Besides that, they needed other preparations. To disguise themselves as Evil Demons, Zhu Yanyi had to make special arrangements. The black aura surrounding Evil Demons was hard to fake and couldn’t be replaced by anything else. So, she chose to use medicine.
She decided to enter seclusion to refine the medicine. Everyone knew why she was doing it, so no one disturbed her.
Actually, Zhu Yanyi entered the Ruyi Space to refine the pills. One day outside equaled one month inside. This gave her enough time to create the perfect medicine for their needs.
To make the medicine that caused black smoke to rise from the body, she experimented countless times before finally succeeding. To test the effect, she took the medicine inside the space first. After confirming it was safe, she took the antidote and exited the space.
She spent two months inside the space, which was only two days in the outside world.
When she came out, the others gathered around. Yue Zhuo handed them four sets of black clothes. “I made these based on the Evil Demons’ attire. I don’t know if it will work.”
“Let’s try. Besides, Evil Demons rarely interact with each other. They fear being devoured, so friendship among them is impossible. This gives us a better chance to blend in,” Zhu Yanyi said. She had studied the Evil Demons. Their mutual distrust created a gap for them to exploit.
If the Evil Demons communicated often, infiltration would be hard. But since they suspected each other and didn’t know one another well, it was easier for Zhu Yanyi and her team to slip in.
“After we leave, Brother Sikong and the others will cover for us,” Zhu Yanyi said.
“Don’t worry. Once you leave, I will tell everyone we are going to test various medicinal techniques. I will lead them away for seven days. No one will notice you are gone from our group,” Sikong Xuran said seriously.
With Sikong Xuran’s cover, the next day, Zhu Yanyi, Yi Yunfei, Ouyang Tianyun, and Hong Mei quietly left the camp early in the morning. They departed unnoticed.
Usually, they hired flying boats to kill Evil Demons. However, Yi Yunfei and Ouyang Tianyun each owned a flying boat. This time, they used Yi Yunfei’s. They boarded and headed east.
After flying east for about an hour and a half, they saw a mountain. Seeing it was different from reaching it.
“When did this mountain appear here?” Hong Mei asked curiously, looking ahead.
Zhu Yanyi glanced at her. “Have you never seen this mountain before?”
“No,” Hong Mei nodded firmly. “We have traveled this direction many times, sometimes for hours, but never saw this mountain.”
Zhu Yanyi pondered for a moment, then said slowly, “I think it is an illusion.”
Seeing their curious expressions, Zhu Yanyi smiled. “It is just an array. It makes visible things invisible, like this.” She pointed slightly at her rocking chair in the flying boat. Suddenly, the chair disappeared. She pointed again, and it reappeared.
“However, my cultivation is not enough to hide an entire mountain. This mountain is hidden by Zhan Diting’s technique,” Zhu Yanyi said with a faint smile.
She was correct. It was indeed Zhan Diting’s doing. she resided in this plane, needing only her pressure and aura to be present. she didn’t need to appear, so she lived leisurely in this mountain. Later, when the number of Evil Demons increased, she went out to check.
Since this mountain was his temporary residence, he naturally didn’t want others to find it or disturb him. An illusion was the best choice.
“I didn’t know such arrays existed. We should learn this. It is useful. In the future, no one will find us when we hide,” Ouyang Tianyun said seriously.
Zhu Yanyi glanced at her. “Your cultivation is not low. Don’t say such things casually. Besides, this illusion is just a common array. You can find it in any array book.”
“But I always read cookbooks and recipes. I rarely read array books. Now that I see this array, I really want to learn it when I have time,” Ouyang Tianyun said honestly.
Zhu Yanyi frowned slightly. “Learning arrays is fine. But didn’t you learn medical arrays when studying medicine?”
“I have heard of medical arrays, but I had no time to learn them,” Ouyang Tianyun told Zhu Yanyi honestly.
Zhu Yanyi sighed. “As a healer, medical arrays are a very important part of medicine. I suggest you learn them when you have time. Once you master medical arrays, you will understand these common arrays naturally. You won’t need to study them separately.”
Zhu Yanyi kindly gave them advice.
Ouyang Tianyun looked at the mountain. They still had some time to arrive. “Fifteen, why don’t you introduce medical arrays to us?”
Zhu Yanyi thought about it. They had time, so explaining was fine. “I can explain. Since we have some time, I will give a brief introduction.”
Zhu Yanyi organized her thoughts and words, then continued. “As healers, we often cannot use medicine to its fullest potential because the human body has a limit. If we exceed this limit, it leaves regrets. Medical arrays can remove these regrets, adjusting the body to its best state.”
She paused, then added, “Many regrets cannot be fixed. For example, someone who dies of old age. But we can reduce their suffering. Especially when pain is caused by unnecessary troubles.”
“You mean medical arrays can reduce this suffering?” Ouyang Tianyun asked.
Zhu Yanyi nodded slightly. “Let me give an example. My dear grandfather was framed by a conspiracy. She lost her sight, her tongue was cut off, and her legs were broken. How would you treat her?”
