"Cinnabar?" Wu Zhongyuan said to himself. He was not unfamiliar with Cinnabar. The book of medical practice left by his master seemed to mention it. In addition, Taoist priests often use this thing to draw talismans.

Dean Wang said, "Cinnabar has the effect of calming the mind. Western medicine will not contain this ingredient. Only Chinese medicines are occasionally used. However, cinnabar is toxic and even traditional Chinese medicines rarely use it now."

"We all wish she would wake up early. The function of cinnabar is to calm the mind, and it is not right." Wu Zhongyuan looked at Dean Wang in confusion.

Dean Wang also wanted to solve Wu Zhongyuan's doubts, but he himself couldn't figure it out.

At this moment, Wang Xinran said from the side, "Cinnabar has another purpose."

Wu Zhongyuan and Dean Wang turned to look at her at the same time. Wang Xinran said, "In the past, Taoist priests would use it to refine elixirs. Ancient elixirs were unearthed in ancient tombs such as Mawangdui and Wang Danhu. We also tested their ingredients and there was cinnabar inside."

After Wang Xinran finished speaking, Wu Zhongyuan suddenly realized, but he was only "a great enlightenment" by himself and did not dare to tell Wang Xinran the truth. He had given Zhao Ying three different bottles of elixirs from the middle-aged Taoist bag to ask her to take it back for the job. Now it seems that Zhao Ying and others may have tested their ingredients and determined their purpose. Huang Ping took one of the three elixirs.

While Wu Zhongyuan was guilty, Dean Wang had reached a consensus with Wang Xinran. Huang Ping inserted an oxygen tube and could not drink thick medicine. It was very likely that the person who came to feed her an ancient pill.

"What do you think?" Wang Xinran sought Wu Zhongyuan's opinion.

"Hmm? Well! It should be." Wu Zhongyuan nodded.

"What are you thinking?" Wang Xinran keenly discovered that Wu Zhongyuan had just been distracted.

"I'm wondering if it's my brother who is with Zhao Ying." Wu Zhongyuan did not avoid President Wang. The owner of the clothing factory who was killed by Lin Qingming was from Huang County. This matter was quite big, so President Wang couldn't not know.

Wang Xinran did not answer the conversation, but raised her hand and looked at her watch.

Seeing this, Wu Zhongyuan knew that she didn't want to say more here, so he thanked Dean Wang, said goodbye, went back to the ward to explain a few words to the old nurse, and then left the hospital with Wang Xinran.

There is no military hotel in Huang County, and only a public guesthouse. Naturally, the conditions cannot be compared with the hotel in the provincial capital. However, it is still okay. The environment is quite good. The most important thing is that the facilities are old and there are no people to live in. It is very quiet and not far from the library.

As usual, it was still one room, but the guesthouse did not have a suite, and each room only had one bed. After entering the door, Wu Zhongyuan was worried. How could he sleep at night?

Wang Xinran didn't say anything on the way, and the first thing he said after entering the door was, "Did you hide something from me?"

"What did you say?" Wu Zhongyuan tried to get time to think through retort.

"How could your senior brother be with her?" Wang Xinran asked.

"I really don't know," Wu Zhongyuan shook his head, "I have no contact with my brother either."

"Did your senior brother know her before?" Wang Xinran asked again.

"I have met once, but I haven't said anything, so I can't be considered acquaintance." Wu Zhongyuan said. Lin Qingming went to college to see him and saw Zhao Ying. He also reminded him that Zhao Ying's eyes were not right.

"Since they are not familiar with each other, why are they together?" Wang Xinran asked.

"Here you come again, ask me, who will I ask?" Wu Zhongyuan shook his head, and Wang Xinran's questions were also bothering him.

Wang Xinran was about to answer the conversation when a knock came from outside the door. The knocking sound was three long and two short, as if it was some kind of secret code.

Wang Xinran stood up, walked over and opened the door. Two young flat heads walked in, each carrying a small black suitcase in his hand.

Wu Zhongyuan had never seen these two people before, but Wang Xinran seemed to know them. After letting them in, he said, "Thank you for your hard work."

The two nodded at Wang Xinran. One of them opened the suitcase, took out a small square box wrapped in tin foil and handed it to Wang Xinran.

Wang Xinran reached out to take it, tore open the tin foil, opened the box, took out a piece of white jade from it, and threw it to Wu Zhongyuan.

Wu Zhongyuan hurriedly caught it and looked closely. It was Wu Qianshan's spirit stone.

After the handover, the two little flat heads did not stop for a long time and turned around and left with their suitcases.

When Wang Xinran closed the door, Wu Zhongyuan asked, "Is the other small suitcase empty?"

"Yes," Wang Xinran nodded, "It is the way to transfer important items, so you must ensure that everything is foolproof."

"No wonder it's so slow." Wu Zhongyuan said. Wang Xinran asked the headquarters to send the spirit stone seven or eight days ago, but it was not delivered until today.

"This stone is a public property. To give it to you, it requires complicated procedures." Wang Xinran said.

Wu Zhongyuan didn't answer the conversation, opened his backpack and put a few spirit stones together, one middle-aged Taoist, one Wu Zhui, one Wu Qianshan, one bird man, and four now.

Although she was in the same room, Wang Xinran never moved Wu Zhongyuan's things. It was not until Wu Zhongyuan took out two books that originally belonged to the middle-aged Taoist for a place that she noticed that Wu Zhongyuan brought two books and took them over and took them to take a look, "What are you studying these?"

"This is not mine, it is the middle-aged Taoist wearing armor," said Wu Zhongyuan. "The tribe that man belongs to is good at smelting metal to build armor. One of these two books is for mineral search and the other is for metallurgical. He may feel that he can use it after he goes back."

Wang Xinran put the two books back on the bed and got back to the point, "Your senior brother can't take the initiative to find her. It should be that she found you and her senior brother after she found out that you left us."

"There is such a possibility." Wu Zhongyuan said. If Zhao Ying went back, it would be impossible for the Yao woman to not tell her what had happened in the few days she left.

"What do you think is the purpose of her doing this?" Wang Xinran asked.

"Let me go back and find her." Wu Zhongyuan said. Although Wang Xinran was asking questions, she had already had an answer in her heart.

"Yes," said Wang Xinran, "They came last night, we will be here today. Things cannot be so coincidental. If I guess correctly, she should know where we are, and even know our itinerary. She expected that you would definitely go to see Huang Ping when you return to Huang County, so she deliberately left a clue to indirectly tell you that your senior brother is with them now."

"So," Wu Zhongyuan tilted his head to look at her.

Wu Zhongyuan asked her to continue, and Wang Xinran continued, "She should know that your senior brother has a murder case, and she also knows that you and your senior brother have a good relationship. At the same time, she also knows that we do not have the right to pardon your senior brother. She is seducing you to cooperate with them, at least they will not arrest your senior brother."

Wu Zhongyuan was worried and silent.

Wang Xinran asked again, "Where did the pill she gave to your sister-in-law come from?"

Wu Zhongyuan tilted his head and glanced at Wang Xinran, but still did not answer.

"Did you give it to her?" Wang Xinran asked.

"Why guess so?" Wu Zhongyuan did not deny or admit it.

Wang Xinran said again, "Because this kind of elixir can only be preserved if it is buried in the grave. You once told me in the hotel in the provincial capital that the Taoist priest carried some gold from different ages with him. These golds are likely to come from graves from different ages. The gold is not with you, so of course it is with her. Did you give her the elixir and gold together?"

Wu Zhongyuan smiled, a bitter smile.

Looking at Wu Zhongyuan's expression, Wang Xinran knew that he had guessed correctly and asked again, "How many pills are there in total?"

Wu Zhongyuan shook his head, "I don't know, there are three bottles, each containing elixirs. I don't count how many of them, and I don't know which one my sister-in-law took."

"You are so generous," Wang Xinran showed a contemptuous look again, "What benefits did she give you?"

"She's sleeping with me." Wu Zhongyuan said.

"Really?" Wang Xinran frowned.

"Isn't that what you mean?" Wu Zhongyuan took a deep breath.

Wang Xinran also knew that Wu Zhongyuan was talking nonsense and was also understanding that he was in a bad mood, so she stopped arguing with him. "The facts have proved that the pill she gave to your sister-in-law is really effective. She will use this to threaten your senior brother and force your senior brother to cooperate with them."

"She is not as despicable as you think." Wu Zhongyuan couldn't help but retort.

"Okay, even if she doesn't harbor your senior brother, your senior brother will take the initiative to work for them in exchange for the elixir in their hands." Wang Xinran said.

Wu Zhongyuan did not respond because Wang Xinran said the truth.

"What are you going to do now?" Wang Xinran asked.

Wu Zhongyuan did not answer the conversation, pondered for a long time, and took out his cell phone from his own bag.

"What do you want to do?" Wang Xinran asked.

"I'll call her to see if my brother is with her..."
