Zhu Yanyi understood everything after checking. She opened her eyes, lowered her hand, and carefully placed the pulse pillow back into her medical box before speaking.
"Twenty-one hidden injuries, and eleven shrapnel pieces still inside. Old Master, your endurance is amazing." She gave a thumbs-up. Her heart felt even more certain about Old Master Yun’s identity.
"Is that all?" Old Master Yun asked. She was surprised by Zhu Yanyi’s medical skills. She knew Old Master Yun would never tell her her condition. Although instruments could detect some things, she knew her body well. Her pain likely came from more than just these issues.
Zhu Yanyi shook her head slightly. "That’s just the surface. You could check that with instruments. But what you don’t know is that there is a Seven Absolutes Array inside your body. This array is arranged cleverly, using your twenty-one hidden injuries and eleven shrapnel pieces. However, the person who set this up probably isn’t skilled enough. They don’t realize that the Seven Absolutes Array is related to the number seven. Twenty-one injuries fit the 'three times seven' principle. But eleven shrapnel pieces do not fit. To fit, it should be either fourteen pieces for 'two times seven', or four healed leaving seven for 'one times seven'. Eleven pieces clearly shows they didn’t understand the array’s principle."
As she spoke, Zhu Yanyi sighed, looking a bit regretful, as if pitying the imperfect array. The people nearby found this amusing and confusing. Inside, Zhu Yanyi was curious. Who could set up such internal arrays for both Old Master Yun and Yan Aohan? If Yan Aohan’s Three Kills Array was a coincidence, Old Master Yun’s Seven Absolutes Array proved that coincidences were rare in this world.
"Can it be cured?" Yan Aohan cared most about this. She remembered Zhu Yanyi saying she only learned basics. She worried it might be too difficult for her.
Zhu Yanyi glanced at Yan Aohan. "You came to me because you know I can cure it. You are lucky. I just studied seven-number internal arrays last month. The Seven Absolutes Array is the simplest among them. It’s even easier than the Three Elements Array. But looking at this layout, the person probably only knows simple arrays. If it were an eight-number or nine-number array, I couldn’t cure it soon."
Yan Aohan nodded slightly. "Do all internal arrays start with numbers?"
"Yes." Zhu Yanyi nodded, then shook her head. "Not all. There are others, but most start with numbers because they are easier to remember. Currently, the most powerful number-based internal array is Ten Thousand Waters and Thousand Mountains. Don’t let the nice name fool you. It is very painful. It uses human body structure to create a landscape of mountains and rivers inside the body. Once activated, the pain is indescribable. It is like being unable to live or die. It gives you a chance to die, but you cannot escape the endless pain. However, rest assured. Although I won’t boast, I can tell you for sure that no one in the world can currently set up Ten Thousand Waters and Thousand Mountains. In other words, if I cannot set it up, no one else can."
