Yun Chang lifted her foot into the study.
The ghost doctor and Xu Er followed Yun Shang and walked in. Yun Shang took out the map of Wu'an City from the bookshelf beside him, dipped his pen in ink, and drew a line on the map.
"It takes about three quarters of an hour from Kefu to Miaoshoutang."
"After I took the medicine, I paid attention to where I was at that time, and it was here."
"This is a single road. There is no way to diverge. If you walk forward here, you will have a fork in the road. If you diverge from here, there will be an hour's time difference in the middle, and a back and forth, a place you can go..."
Yun Shang drew a circle on the map: "This is the place inside this circle."
"It's just that, because He Chuling must have seen me halfway through, and should have someone check on my situation, so it should be possible to narrow this circle down a bit."
The ghost doctor didn't have much interest in these things, and walked around idly by.
Xu Er looked carefully at the circle drawn by Yunshang, then raised his eyes to look at Yunshang again, frowning slightly: "This circle is actually a bit bigger."
Yun Chang nodded: "Yes, this circle is indeed a bit big, covering almost half of Wu'an City."
"It's just..." Yunshang nodded lightly with her finger on the map: "It's just that He Chuling can't find a completely unfamiliar place to wait for me to arrange for interrogation. Before, have you ever noticed that He Chuling usually likes me?" Where did it appear?"
"Or, in this Wu'an City, besides Xia Houjing's house, did she ever have another place to live?"
Xu Er thought about it carefully, and raised his eyes to look at Yunshang's expression: "Yes, when He Chuling just arrived in Wu'an City, he lived in a courtyard in the west of the city for about a month."
"Later, I moved to Xia Houjing's place, and went in and out with Xia Houjing in an open and honest manner."
Xu Er glanced at the map of Wu'an City unfolded on the table, and tapped lightly on one of the places on the map.
Yun Chang looked down and found that the place he pointed happened to be in the circle she had drawn before.
"here?"
"yes."
Yun Chang's eyes fell there, but Xu Er who was on the side suddenly remembered something: "If it's as your mother said, then the carriage driver is really suspicious."
"The carriage driver told me earlier that nothing special happened on the road. He took you all the way from Kefu to Miaoshoutang..."
"When I went out earlier, I heard the carriage driver talking to the steward, saying that the carriage stopped, and seeing that you hadn't got out of the carriage for a long time, he asked the steward if you fell asleep in the carriage."
Yun Shang narrowed her eyes: "The carriage driver, is He Chuling's man? Or, controlled by He Chuling?"
"Do you want to bring the carriage driver in for questioning?" The ghost doctor suddenly became interested: "I have improved the medicine that I gave you before, and I just need someone to test it."
Yun Shang glanced at the ghost doctor: "But if he was controlled by a Gu worm before, your medicine may not be useful to him?"
"So I said, I've improved."
Yun Shang was skeptical, but she still trusted the ghost doctor's ability to make poison, so she nodded, turned to the commander of the hidden guard and said, "You go down first, Xu Er will find the carriage driver..."
Yun Chang said, and glanced at the dark night outside the window again: "It's about this time, the carriage driver has already gone home, right?"
"No." Xu Er shook his head: "I was afraid that there would be something wrong with the carriage driver, so I deliberately left the carriage driver behind."
"Okay, you go and find him, just say that I have woken up, and I can't remember why I am unconscious. Tell him to come over and I have something to ask."
Xu Er responded and hurriedly retreated.
Waiting for Xu Eryi to leave, the ghost doctor smiled, took out a small bottle, and poured a drop of the contents into the lamp oil.
"What are you doing?" Yun Shang raised her eyebrows: "What you put was the drug used by the interrogator before?"
The ghost doctor nodded: "Don't worry, you are invulnerable to all poisons. Although this thing is called a drug, it is also a poison."
"..." Yun Shang naturally doesn't have to worry, but: "Isn't there Xu Er?"
As soon as Yun Shang finished speaking, she saw Xu Er walking in from the door: "Madam is calling you?"
Yun Shang opened her mouth, saw the person behind him, swallowed the words again, and just nodded: "It's nothing, it's just that senior brother said that if something happened to me, this Miaoshoutang should what to do?"
"I said, you will take care of me, it's fine."
Xu Er nodded, and stepped aside a little: "Ma'am, this is the driver, his name is Niu Qing, and today is the Ke Mansion where he sent Ma'am."
Yun Chang responded, but glanced at the ghost doctor beside him, didn't he put the medicine in the lamp oil? Why didn't it work
Yun Chang was thinking in her heart, when she saw the ghost doctor's gaze resting on Xu Er's body indistinctly, with a somewhat thoughtful expression.
Yun Chang's mind moved slightly, and she looked at Niu Qing behind Xu Er, and saw that Niu Qing's eyes were slightly distracted.
Yun Shang and the ghost doctor looked at each other, and they both found a serious look in each other's eyes.
Yun Chang's fingers hanging on the side slightly curled up, and then she spoke again: "The ghost doctor said that he wanted to prepare some medicine, which will be useful later, Xu Er, go and help him."
Xu Er responded, and the ghost doctor also stood up, but walked straight to Yunshang, blocking Xu Er's gaze: "Where are the things? You asked me to help you make medicines. There are medicinal materials, but only you can get them." some."
"Tsk, that medicine is expensive, so why don't you think of other ways to use that medicine?"
"Then I don't know when it will be matched."
Yun Chang's mind was spinning quickly, and in a place Xu Er couldn't see, she said three words to the ghost doctor with her lips, and then made a gesture.
Then I stood up, found a small white porcelain bottle from the bookshelf and threw it over: "Here, that's all there is. The medicinal materials in the city can't get in, so we need to save some."
"Stingy." The ghost doctor got up and went out of the study with Xu Er, and Yun Shang quickly called out the leader of the hidden guard: "Xu Er, it's suspicious. I gave the ghost doctor a bottle of oil. If the ghost doctor later After confirming, you will find a way to sprinkle the oil on Xu Er's body, and you will find a way to light a fire and burn it."
The leader of the dark guard responded and quickly retreated.
Yun Shang also ignored the carriage driver who stood aside with slack eyes, only frowned, and kept remembering in her mind, when exactly
When did something wrong with Xu Er... Is it today, or before
If today is still okay, Xu Er has not left Miaoshoutang after she came back. If it was before, then...
