Tuoba Jing, the eighth prince of Beimang, suffered from a strange disease.

"This disease is called 'ice disease' in the Ming Dynasty, and it is called 'frozen death disease' in Beimang, which means that people who suffer from this disease will have a hard time every winter."

Once the patient becomes ill, his whole body will be as cold as ice, and he will not be able to warm himself up no matter what. If the illness lasts for a long time, the person will freeze to death due to the coldness of the internal organs.

Therefore, Tuoba Jing needed to take powerful warming tonics every day to prolong his life.

"The reason why the Eighth Prince looks so strong is because he uses a lot of tonic medicine." Yun Xi sighed and continued to explain: "In fact, his body has been tortured by illness for a long time and his internal organs are all weak."

"Is there any cure for this disease?" Zong Yi was surprised and asked.

"I can cure it." Yun Xi nodded: "It is better to cure it in Daming."

Firstly, the cold syndrome is caused by the fact that the older generation has this disease and it will show up in the next generation. Secondly, the cold climate causes excessive accumulation of cold air in the body, affecting the internal organs.

As long as Tuoba Jing comes to the south of the Ming Dynasty to be warmed up, and supplemented by Yun Xi's prescription, he can recover in a few years. However, after recovering from the illness, His Highness the Eighth Prince may no longer be able to adapt to the harsh and cold weather in Beimang, and he will have to stay in the Ming Dynasty for the rest of his life.

Spent it.

"You are a little fool, but you know a lot." Zong Yi looked at Lu Qingfan with a smile but not a smile: "Master Lu has a sharp eye for pearls!"

"Yun Xi studied in the Valley of Miracle Doctors, and some difficult and complicated diseases are really not a problem for her." Lu Qingfan explained patiently.

Ren Danqing was not happy when he heard this, "You people in the capital are so reserved in your speech! What kind of 'difficult and complicated diseases'? Ice syndrome is considered an incurable disease even in the Ming Dynasty!"

People born in the harsh regions of the north are more or less susceptible to "ice syndrome". Even in the rich and warm Jiangnan, there are still people who die from the wet, cold winter.

Yun Xi can cure the "ice syndrome", and it is not an exaggeration to call her a "miraculous doctor".

Yun Xi smiled sheepishly, "I really don't deserve Master Ren's praise. Ice syndrome is indeed not difficult to treat, but it is a bit difficult to deal with."

The little girl spoke in a humble manner, which attracted everyone's attention and admiration.

"No wonder Tuoba Jing always goes to dawn in winter. It turns out to be to warm up his body." After Lu Qingfan finished speaking, he began to question again: "But now it is almost the dog days of summer, what is he doing here?"

Yun Xi raised her eyebrows and explained: "Winter diseases can be treated in the summer. If I guess correctly, His Highness the Eighth Prince may be planning to stay in Ming Dynasty for a long time to recuperate his health."

"The eighth prince Tuoba Jing has the ability to compete for the throne. Especially in the past few years after Beimang surrendered to the Ming Dynasty, government affairs were almost divided among several princes. I think he finally chose the latter between power and survival?"

Ran Piao got to the point with his words.

The question then falls on why the criminal wanted to kill a prince who was not prepared to seize the throne.

"Master Yi must know something about this." Lu Qingfan said thoughtfully.

Yun Xi also made the inference about the murderer: "This person's personal status has been mentioned earlier. He is well versed in the customs and customs of Beimang and Daming. He is acquainted with the Eighth Prince and knows Lord Yi."

Yun Xi thought for a while and said: "He is probably a person who is better at holding paper and pen. There is always something awkward when he is lying down with a knife, which is somewhat similar to someone who is accustomed to using a pen."

"Civil official?" Ren Danqing said sarcastically: "How brave." What a lonely and courageous spirit.

"This person can accurately predict when Master Yi may enter the study, and he also knows that Master Yi will pick up the murder weapon. He must be very familiar with the Qianyuan Pavilion."

Yun Xi hesitated for a moment, but finally added some more inferences.

Most people would not do such a thing as picking up a murder weapon and examining it. But the criminal took advantage of this and set up a trap for Yi Duo, the Minister of Household Affairs, who also knew him somewhat.

"But the Qianyuan Pavilion welcomes a lot of foreign guests, and there are many people coming and going, so it is not easy to screen." Zong Yi said worriedly: "Not to mention us, even if there are dozens of people to help, we can't finish the investigation in an hour and a half."

"There is no need to check so much." Lu Qingfan stood up and said to Zongyi and Ren Danqing: "Master and Master are traveling day and night. Let's rest at the inn today."

He had a few guesses in his mind, and he had to ask Mr. Yi before settling the investigation.

The sharpening of the sword does not stop the cutting of firewood, Zong Yi and Ren Danqing agreed without refusing.

Yun Xi's autopsy came to an end, and Lu Qingfan also asked her to go back and rest for now, and discuss anything later.

In this way, Zong Yi and his party, Yun Xi's master and servant, and the four masters and servants left the Criminal Department early, leaving Lu Qingfan, master and servant, and Ran Piao still in the room to discuss the matter.

"We have basically obtained all the confessions today. Mr. Ran, you can screen out the missing clues overnight and sort out the useful confessions. We will interrogate the Qianyuan Hall and Beimang guards overnight."

"Yes, sir." Ran Piao responded.

"Leng Hai, send someone to secretly keep an eye on the Qianyuan Pavilion to see who has been coming and going frequently in the past few days. Since the murderer dared to commit murder here, he must have come in advance to check it out."

There were numerous guards in Beimang, including the servants of Qianyuan Hall. They arrived in time after the incident and witnessed Yi Duo picking up the murder weapon... The murderer must not have been able to come and go freely for several days.

"yes."

As for Leng Chuan, Lu Qingfan still has a secret mission for him.

The two whispered a few words into their ears, and Leng Chuan respectfully clasped his fists and left.

"My lord always tells Leng Chuan small things and doesn't let us listen." Leng Hai muttered in a low voice.

"It must be that the adults don't trust you." Ran Piao patted Leng Hai on the shoulder, pretending to be sorry, adding fuel to the fire: "Guard Leng, you still have to find the reason from yourself?"

"What? Mr. Ran drank too much and called his subordinates brothers, but he didn't mind that his subordinates talked too much." Leng Hai immediately became unwilling and argued with a stiff neck.

Lu Qingfan couldn't laugh or cry when he heard this, "Why don't you do something?"

Do you still have time to argue here?!

Ran Piao and Leng Hai glanced at each other and walked away.

Watching the two of them leave, Lu Qingfan subconsciously clenched the sword in his hand and turned his dark eyes to the dungeon of the Criminal Department.

Instinctively, he believed that all the connections in this case pointed to Yi Duo, the Minister of Household Affairs.

As long as the knot is found correctly, the murderer's motive will be clearly known, and it will be much easier to locate the murderer.

Thinking of this, Lu Qingfan didn't hesitate anymore and strode towards the dungeon.

Moreover, Yun Xi’s master and servant enthusiastically sent Zong Yi and Ren Danqing to the inn where they were staying, and also paid for a big meal at their own expense to warm them up, which was considered Lu Qingfan’s courtesy.

During the dinner, Yun Xi did not forget to explain Lu Qingfan's difficult and busy situation after entering Beijing, so he canceled the ceremony due to the case, and asked the two elders to forgive him.

Having said this, Zong Yi looked at Yun Xi with more and more gentle eyes, as if he regarded the little girl as Lu Qingfan's good wife.

"I am Qingfan's master, how could I not know his ambition? You can tell just by looking at me. If it weren't for this kid, I would have retired to Qingzhou and returned to my hometown. How could I possibly go further?"

It is possible for local officials to return to the capital again; it is extremely difficult for local officials to be transferred to the capital.

"Fortunately, lucky to have you, Yunxi!"

Master Zong Yi stopped even calling "Yun Wu Zuo" and pulled Yun Xi's sleeve to complain: "That kid Qingfan has a hard life! He was obviously able to be promoted to an important official in the imperial court, but because of 'that case' he had to give up his career."

Wu. But he has a strong temper. It took him ten years of hard work to achieve what he has achieved now..."

Yun Xi was stunned by Master Zong Yi's sad look with red eyes, "That case?"

"The case happened ten years ago." Zong Yi whispered: "How tragic!"

Yun Xi's face turned pale, "These... adults have never told us."

He didn't mention a word, and Yun Xi never took the initiative to ask about his origins.
