Xiang Yunshang pointed at me and said, "Do you even know what Li Po is doing? He's protecting us, you know? After investigating this matter, Li Po's only conclusion is that someone wants to kill the Yun family, that all the members of the Yun family are going to die. You might be next, do you understand?"

Yun Ya was also so angry her face turned white: "But he shouldn't do things that way! Isn't that indiscriminate killing? Who doesn't have a family, who doesn't have relatives? What right does he have to kill people?"

I was so angry that I laughed and said, "Ye Yang, notify Lao Liu to return the deposit to them, not a penny less. I'll pay for the shop's expenses these days myself."

"Li Po!" Xiang Yunshang immediately became anxious: "Don't be impulsive, Yun Ya just hasn't thought it through yet."

I waved my hand to stop her: "Whether she thinks it through or not has nothing to do with me. I'm just settling the karma between us. I hope you understand!"

Without saying a word, Ye Yang picked up the phone and called Lao Liu. I looked at Xiang Yunshang and said, "Miss Xiang, it was a pleasure meeting you. Here's a talisman for you. It can save your life in a critical moment. We'll meet again someday."

After I finished speaking, I pushed the door and left the hotel, ignoring Yun Ya's calls.

After I got in the car, Ye Yang said, "You just left them both like that? This way, you might get involved in karma too."

I sneered and said, "There are so many people dying every day in this world, can I take care of them all? Besides, if the karma here doesn't come looking for me, fine, but if it dares to come looking for me again, I'll let it know who the boss is."

I knew what Ye Yang meant.

Yesterday, he noticed something was wrong with Yun Ya at the hotel. At the time, we both remained calm to find out what was going on, which is why we didn't go directly to find Number Fourteen.

We had just found a clue when Yun Ya fired us. Without anyone to look after her, Yun Ya will definitely encounter a crisis. But that's no longer something I need to consider.

A术士 (Shushi) without an employer must never get involved in karma – that is the iron rule of the术道 (Shudao).

Similarly, few people with overflowing sympathy can survive in the martial world.

Ye Yang didn't say much to me, but Lao Liu was so angry that he pointed his finger at me, trembling: "You, did you eat everything your master taught you?"

"What is 'black heart, ruthless hand, thick skin'? Why don't you take any of it to heart?"

"That Yun Ya is obviously a young lady who doesn't understand the ways of the world. The things she's thinking about aren't what ordinary people think. She's feeling bad, wouldn't it have been fine to just go along with her?"

"With that kind of person, you treat her like a goddess, everything she says is right, everything she does is good, and she'll definitely see you as a confidant. In private, how would she even see what you're doing?"

"Such a good deal, ruined in your hands like this, tell me, what am I supposed to say to you?"

"Bah!" I spat, almost hitting Lao Liu in the face: "I'm a 术士 (Shushi), not a servant. I'm not counting on her to live, why should I listen to her?"

Lao Liu slammed a yellowed file on the table: "Take a look for yourself, what is this? Take a good look at what's written in the Yellow Springs Secret Files!"

I casually flipped through the file; the secret language on it had been translated into Chinese characters by Lao Liu.

According to the records in the Yellow Springs Secret Files: The Black and White Medical Hall is also known as the Human-Ghost Doctor. It is a medical hall opened by a human and a ghost working together. They treat humans during the day and ghosts at night.

The biggest characteristic of the Black and White Medical Hall is that it has two consulting rooms, front and back, and two doors. The front door is opened during the day with a red lantern hanging. The back door is opened at night with a white lantern hanging. The lit lantern indicates that someone is on duty.

The doctors of the Black and White Medical Hall only sit in the hall and do not make house calls.

The surname of the doctor in the hall must be related to black or white.

I closed the file and said, "So, the Yun family should be the human doctors of the Black and White Medical Hall?"

"It could also be the ghost doctors!" Lao Liu said, "The color of clouds is also divided into black and white. Truly skilled ghost doctors can treat humans during the day and ghosts at night."

I roughly understood: The reason Yun Sheng would meet a ghost begging for help at the old baldy's place was probably because he could treat ghosts.

I glanced at it and pushed the file back: "The business is already ruined, what's the use of looking at this?"

"You're stupid!" Lao Liu was so angry that he blew his beard and glared: "You find the Black and White Medical Hall and capture the ghost doctor inside. Wouldn't we have a medical hall then?"

"When you're injured, or someone needs medical treatment, wouldn't we be making a fortune? Besides, with a Black and White Medical Hall in our building, how much information could we get? The Yin and Yang worlds might even have to buy our favor! How great is that benefit? Why don't you think about it?"

"Forget it!" I said dismissively: "Do you think ghost doctors are dogs? If you say something, they'll listen to you? If they prescribe rat poison for you, I'd have to beg the ancestral master to release you, wouldn't I?"

"Get lost!" Lao Liu was about to go crazy: "Other places won't work, but what kind of place is this? We have the Yellow Springs Secret Files in our hands. As long as we have the Yellow Springs Secret Files, we can detain ghosts here and make them obey our orders, do you understand?"
