Yang Wenxin nodded slightly: "At present, this is the only way."

"Let's go and say goodbye to Hu Yunan."

Li Xiuran said lightly and turned around and walked out the door.

Yang Wenxin and Chi Qingwan followed closely behind.

Back at the main hall and looking at the three people entering the door, Hu Yunan said directly: "How is it, what did Li Shidu find?"

Li Xiuran shook his head: "But the officials have already had a preliminary investigation direction. Now we will go to investigate and not disturb the Duke of Wei."

"I would also like to ask Mr. Li to find out the case and find out the culprit of killing my son! Mr. Hu must thank him." Hu Yunan said seriously.

"The officials must do their best."

Li Xiuran responded, and with Yang Wenxin, Chi Qingwan left the Hu Mansion together.

Hu Ruikang offended basically all the playboys like him. His family is full of high-ranking officials and most of them live in Pingkangfang. It is much more convenient to investigate.

Li Xiuran asked for a brief inquiries and found Liu Shilang's house.

"Who are you? The master is not at home, come again the next day." Seeing the three of them coming in, the doorman immediately came out to stop him, with an impatient feeling on his face.

Li Xiuran looked at him: "I am the minister of the Hongjiao Palace, and I will investigate the case under the order of Your Majesty. Can Master Liu be at home? I have something to ask him."

"It turns out it's Lord Li. Here, the eldest son is at home. Several adults invite in first, so the villain will call the eldest son out."

Hearing the order to investigate the case, the concierge's face changed and he did not dare to neglect any more. He quickly invited Li Xiuran, Yang Wenxin, Chi Qingwan and the other two into the door, and then quickly walked towards the back house.

After a while, he walked out of the back house with a man in his thirties and was dressed in an extravagant manner. Seeing Li Xiuran, he bowed and said hello from afar:

"Li Shidu, I have heard of the name of the name for a long time. Feng Kai and I have known each other since I was a child. I originally wanted to ask him to help introduce him another day. When I met Li Shidu, I didn't expect that Li Shidu would come to the door first. Fortunately, I will be lucky."

"Young Master Liu, please be polite." Li Xiuran smiled slightly.

"Just just now, the gatekeeper said that Shidu Li is under the order to investigate the case. Is there something to ask me? It's not Hu Ruikang's business, right?" Liu Jin said with a smile.

The news is quite well-informed... Li Xiuran looked at him and said, "That's right, it seems that Mr. Liu already knows about his death."

"We all live in Pingkangfang. How could we not know about such a big thing?" Liu Jin smiled: "Li Shidu came to me. Could it be that he suspected that this matter had something to do with me, right?"

Li Xiuran said lightly: "I am just here to learn about the situation from Mr. Liu, so Mr. Liu doesn't have to worry."

"Haha, that's great. Just ask what Shidu Li wants to ask directly. I will definitely tell you everything I know." Liu Jin said with a smile.

"I heard that Mr. Liu and Hu Ruikang are a little disagreeable?" Li Xiuran said straight to the point.

Liu Jin nodded: "I had a little quarrel before, so I've made some trouble."

"Why did the quarrel happen?"

"This..." A hint of embarrassment flashed across Liu Jin's face: "I'm not afraid of Li Shidu's jokes. It was in Tianxiang Pavilion last year. Originally, I fell in love with the courtesan Yurou first, but he relied on his son of the Duke of Wei and snatched the person over.

I was resentful, so I had a quarrel with him."

"Is it just a quarrel?"

"Otherwise? It's not good for anyone to make such a big deal. And although he is hateful, he is the son of the Duke of Wei after all. Xu Madam from Tianxiang Pavilion also came to persuade him to make peace. Although he was angry, he could only swallow his breath."

"Have you seen Mr. Liu recently?"

"Everyone lives in Pingkangfang, he will inevitably bump into it, but he has always been arrogant and domineering because of his identity. He can't afford to mess with him, but he can still hide. Since then, he has never been with him again."

Li Xiuran nodded slightly, and carefully examined his expression while speaking, confirming that he didn't seem to be lying.

If he was just jealous, it was really not a big grudge. He shouldn't have the intention to kill because of this little thing, and his suspicion could basically be ruled out.

"Does Li Shidu have anything else to ask?" Liu Jin asked.

"No need, thank you Mr. Liu for telling me, I won't disturb you." Li Xiuran said goodbye.

"You are polite to Shidu Li. If you have any questions, Shidu Li will come at any time and will cooperate." Liu Jin breathed a sigh of relief and smiled.

"Then I will thank you first."

Li Xiuran smiled slightly, and with Yang Wenxin, Chi Qingwan left the Liu Mansion together.

"From his reaction, it doesn't seem like he is lying. This matter should have nothing to do with him." Yang Wenxin said lightly.

Chi Qingwan nodded slightly, obviously not finding any suspicion.

"Continue to investigate."

Li Xiuran didn't expect the first person to make a breakthrough. After asking for a brief inquiries, he went to the next family with Yang Wenxin and Chi Qingwan.

...

After checking all the people who had had a holiday with Hu Ruikang in Pingkangfang. Except for a few people who were not at home and could not be asked, Li Xiuran checked all the others, but found nothing.

Then the three left Pingkangfang and continued to investigate people outside Pingkangfang.

Although it has been confirmed that Buyuan Yiqi Pill is not poisonous and Hu Ruikang's death should have little to do with this, to be safe, Li Xiuran and Yang Wenxin and Chi Qingwan found Yihetang together and prepared to investigate it on the spot.

The clinic is in the suburbs of the city, which is a bit different from what Li Xiuran expected. I heard Ah Fu say before that Yihetang is quite famous in the city. He thought it was at least a large clinic. After coming here, he found that the so-called clinic only divided several halls at home and had a sign hanging at the door. This is simply a family workshop.

However, a medicinal field was planted outside the yard, and the care was well organized, which looked quite pastoral.

Li Xiuran looked around and walked into the yard with Yang Wenxin and Chi Qingwan.

In the clinic, an old man wearing a gray robe with a half-white hair and a kind-faced face was sitting in the hall and bandaging the patient's hands: "Okay, a little skin trauma will grow well in three to five days. Don't worry, remember not to touch the water, come here to change the medicine once a day."

"Thank you, Dr. Cui, I will remember it." The patient thanked him with gratitude and stood up and left.

"Are you Doctor Cui from Yihetang?" Li Xiuran stepped in and looked at the old man and said.

"I, Cui Soon, what are you doing?" The old man looked at the three people entering the door with a little confused face.

"I am the official Li Xiuran, the official guard of the Demon Suppression Department, there is a case involving you. I am asking you some questions. Please answer truthfully." Li Xiuran said lightly.

The position of attendant is not mentioned, for ordinary people, the Demon Suppression Department is more intimidating.

Cui Shun frowned slightly: "Master, please ask."

Li Xiuran looked at him and said, "Hu Ruikang, the third son of Duke of Wei, bought Buyuan Yiqi Pills from you, do you have any impression?"

Cui Soon pondered a little, nodded and said, "Young Master Hu has indeed been here."

"When did he first start?"

"It should be four months ago."

Li Xiuran smiled faintly: "Doctor Cui remembers it very clearly. In addition to Buyuan Yiqi Pills, he has also purchased other medicines? Have you ever asked you to treat him?"
