Yun Xi smiled, she knew that Lu Qingfan would definitely not be able to guess.

"Everyone knows that honey is sweet, but in fact, the honey produced in various places is divided into many types according to the climate and color of nectar."

There was no nectar or honey in Bo Niang's room. After reading the purchase books of Feiyan Building, Yun Xi found that he never bought any nectar or honey in Feiyan Building, and sugar was the main thing for sweets.

Because Bo Niang doesn’t like the fragrance of honey and nectar, she is not allowed to eat it by other women in the building. She also said that her face is more likely to age after eating honey and nectar...

"So, honey was brought by the murderer." Lu Qingfan said confidently.

The murderer went to Feiyan Tower. At first, he did not have the intention to kill, so the honey was the thing the murderer carried with him. Later, he did not go well, so he suddenly had a whim to use honey to torture the confession.

Unexpectedly, he failed to pry Bo Niang's mouth in the end, and the murderer finally returned in vain and killed someone to silence him.

“What the adults said is.”

Yun Xi told everyone about his discovery in honey: "The ancient formula says: 'The white honey in Guanzhong is sweet and beautiful, and it is better than Jiangnan'."

She showed everyone the little honey dew twisted by her fingertips and explained patiently: "This is the most famous 'Guanzhong White Honey'. Many places in Jiangnan are responsible for refining white honey..."

Only by looking at people who have entered Beijing from Guanzhong’s white honey in recent years, who are good at capturing and can get knots, can the scope of screening criminals be greatly narrowed.

"People who have close contacts with the Ministry of Revenue and Feiyanlou should also focus on screening." Lu Qingfan added.

When the others in the house saw Yun Xi and Lu Qingfan making tacit confusions as if no one else had, they all silencedly ate dog food.

It was not until the topic was re-introduced to the next task that Ran Piao and Ren Danqing focused on it and said that the matter would be left to them.

Yun Xi and Lu Qingfan went to the crime site again to find the key to the "Fengzhai Money House".

On the way, Lu Qingfan simply informed Yun Xi of Ran Piao's investigation results.

The little girl sighed after hearing this: "Fortunately, the thing has fallen into the hands of the murderer, so we still have a chance to find out the truth."

After a round trip, I couldn't help but find something.

"Fengzhai Money House is quite famous in the world and has many rules, which is why it is possible to preserve the money of many noble marquises."

In any business dealing with money, who doesn’t pay attention to its relationship with the money bank?

Fengzhai Money House has occupied the right time, place and people from the beginning.

After Lu Qingfan finished speaking, Yun Xi said embarrassedly: "Actually, I also saved things in Fengzhai Money House."

The roster she has in her hand is not the only one.

Just in case, the copy in Yun Xi's hand was copied, and the original work of his father was stored in Fengzhai Money House. It was because of his characteristic of recognizing the key but not the person that Yun Xi dared to hold such important things

In Fengzhai Money House.

"...How much wealth do you have?" Lu Qingfan seemed to have never asked Yun Xi about her private property. But the little girl could not only buy a house in a prime location in the capital, but also had a private property in Fengzhai Money House... That would cost five hundred yuan.

A bank that can only open an account with two silver dollars.

"Miss has a lot of money!"

Before Yun Xi could speak, Qingguo excitedly counted with her fingers: "The wealthy businessman I saved last time was given about 1,000 taels of silver notes. After leaving the Immortal Island, he was given two night pearls by the aunt who was seeking medical treatment.

…”

Don’t count carefully, the financial resources revealed by these few words are not something that ordinary people can afford.

When Lu Qingfan heard this, he couldn't help but smile and bent his eyebrows, "Not bad."

With so much money to accompany you, you won’t be deceived at will.

When they arrived at Feiyan Tower, the master and servant Yun Xi followed Lu Qingfan in with his brisk steps and the two were still wondering, she had money, how could Lord Lu be happy?!

When he returned to the crime scene, Qingguo followed a beautiful sister and Yun Xi and Lu Qingfan entered the crime scene.

"It is feasible to let Qingguo alone?" Lu Qingfan glanced at Qingguo's back as he left, and a trace of worry flashed through his eyes.

After all, it is a brothel, and the little girl is not well-informed, so don’t be deceived again.

Yun Xi put on a foot condom and said, "Qingguo grew up in a pot of medicine. Ordinary medicines and fun-energy medicines are useless to her. Plus Qingguo's strength... nothing is wrong."

It was not without consideration for her choice to take Qingguo out of the Divine Doctor Valley.

The two of them experienced storms on the road, and Qingguo was not an uninformed little maid.

Qingguo is good at talking about people.

"...Blame me." Lu Qingfan nodded: "This question is unnecessary."

"Puff, sir, we are all grateful." Yun Xi walked in and began to search along the track where the murderer looked through the objects.

Lu Qingfan looked at Yun Xi's busy figure and said to himself: "I don't need you to be grateful."

He never wanted to be grateful.

Yun Xi was the first to look for the secret lattice in the bedroom. He found that there were some ordinary close-fitting clothes and other objects in the building, so he closed the secret lattice.

"What is inside?" Lu Qingfan looked at it without realizing it and asked.

Yun Xi's cheeks were slightly red and she whispered: "Things that have nothing to do with the case, medicine or something..."

Lu Qingfan immediately understood the profound meaning of her words, and his ears became red quietly, so he quickly walked to another place to search for objects.

Fengzhai Money House will make keys based on the characteristics of the owner, and there is no special sign on the key, which is why the murderer was not found.

"What does the key given to you by Fengzhai Money House look like?" Lu Qingfan began to wonder what her key was when he heard Yun Xi said.

Yun Xi blinked slyly, "Guess, sir?"

"Needle? Scutellar?"

"Although I haven't guessed it, it's not far away," Yun Xi smiled and straightened his back and kept it in a silence, "I said I am a doctor, so guess again sir."

Lu Qingfan was stunned, "Prescription?"

Yun Xi widened his eyes, but he didn't expect Lu Qingfan to be able to guess.

She took out a piece of black iron medicine from her bag and signaled Lu Qingfan to see.

Using black iron to make a thin prescription is a "luxury", not to mention the prescription that I don't know how to write down several medicine names in ancient seal script fonts.

Lu Qingfan rubbed for a moment and said in a deep voice: "This word was not engraved in vain, is it right?"

"Well, it's like the pattern of a key. The engraved font can only be opened if it is perfectly embedded in the key hole." Yun Xi said softly: "This unparalleled ingenious thought is the uniqueness of Fengzhai Money House.

.”

The five hundred taels of silver account opening is really worth it.

Yun Xi put the key to the black iron medicine prescription, and the two of them were in trouble in the room with no loops.

"What would be the key that belongs to Bo Niang alone?" Yun Xi gently held his chin and fell into deep thought.

Lu Qingfan looked at the house without any clues silently, and his eyes swept across several corners.

Don't blame the murderer for returning empty-handed. If there is no clear clue, let alone three days, even if it is thirty days, there will be no way to use the second-entry room.

Since there is no breakthrough, you can only use the stupidest method: look for it one by one.

Two hours later, Yun Xi and Lu Qingfan returned empty-handed.

Qingguo jumped and held a pile of food and followed the carriage. Looking at the depressed look of the adults and her own lady, she blinked and said, "Has the lady and the adults found it?"

"Nothing is missing." Yun Xi sighed: "What is it?"

"Since I can't find it this time, I'll look for it next time! The lady and the adults have worked hard, come and try the famous food in Feiyanlou! I heard that these are usually dozens of taels and one dish, today I'm all

Help me, hehe..."

Qingguo stuffed food to Yun Xi and Lu Qingfan all the time, and did not forget to whisper: "The sisters in Feiyanlou have good tempers, they stuffed food to me one by one. Especially the butler sister Xueming..."

The housekeeper Xueming is the second-in-command in the building and the person Bo Niang trusts the most.

It is said that Miss Xueming's life is very miserable. It was picked up by Bo Niang from outside. She has never taken the guests since she entered the building. She is proficient in piano, chess, calligraphy and painting, and is good at attracting customers and settles accounts. It is said that the most famous actors are all

It was trained by Xue Ming.

This is an unexpected gain.

"Qingguo did not leave this in vain." Lu Qingfan fed a piece of dessert that looked good into his mouth.

Yun Xi is right. Qingguo is not a little maid who is not well-versed in the world. She is obviously very capable.

"That's right, I'm so amazing!" Qingguo thrust his chest proudly, and Yun Xi smiled and rubbed Qingguo's little head.

The housekeeper Xueming is in charge of many matters and must know Bo Niang’s private affairs. Then he will be sent to ask.

On this side, Ran Piao and Master Ren also have new clues.

"I went to check it out, and there are indeed some clues!"

Ran Piao put the files he found one by one on the table, and Chong Yunxi said, "These were from Beijing ten years ago, five years ago, three years ago, and one year ago; they often deal with the Ministry of Revenue.

There are also many."

Yun Xi gave Ran Piao a thumbs up: "Mr. Ran is so capable."

"Hey, the little girl is just praising someone? I think I don't exist?" Ren Danqing immediately competed for favor indignation, which made Yun Xi smile helplessly and praised Master Ren for a few words before he finished it.
