"A lot of ingenuity." A hint of sarcasm appeared in Lu Qingfan's eyes, and he took out the fire seal and walked into the dark secret room alone.

He is an expert and bold man, walking neither fast nor slowly, with the air of strolling in a leisurely garden.

From the deep steps to the underground, a spacious main hall appears in front of you, divided into two by a luxurious screen, and behind it is a tea room.

The furnishings in the underground room are completely different from the simple tea shop above, and its level of luxury is comparable to that of a century-old clan mansion.

Bypassing the teahouse, there are corridors on the left and right of the interior, leading to different bedrooms. The bedrooms are all two-entry halls, which can accommodate four or five people at the same time, making them very spacious.

Lu Qingfan looked to the left, then to the right, and finally found blood stains at the end of the right-hand corridor.

Following the blood trail all the way up, Lu Qingfan opened a secret door at the end of the steps, and what he saw was the bloody tea shop.

Lu Qingfan pondered for a moment, then walked around the blood stains and left the teahouse.

When he showed up, Leng Hai who was guarding the door was frightened.

"Hey! Didn't your Excellency go to the back to investigate? Why did he emerge from the tea shop?" Leng Hai muttered while putting away the hidden dart between his fingers.

Almost all the hidden weapons were launched towards the master.

"There is a secret passage." Lu Qingfan finished speaking briefly and comprehensively, then came outside the small room.

When he first saw the closed door, his thin lips pursed slightly.

"Miss Qingguo said that I won't let my subordinates go in and disturb me," Leng Hai carefully looked at his father's face and asked in a low voice, "How about your subordinates accompany you to the secret room again?"

Lu Qingfan glanced at Leng Hai who was eager to try, and there was a touch of interest in his eyes: "That's okay."

Somehow, the back of Leng Hai's neck felt a little cold.

Soon, the cool feeling was confirmed: the adults locked him in the secret room.

Whether it is an iron cover leading to the wasteland or a secret door into the teahouse, it can only be opened from the outside inward without breaking the door.

This is also the reason why there are two bedrooms in the teahouse: to ensure that there is someone outside to open the door.

"An ordinary tea shop requires seven people to take turns guarding it; they are watching the shop on the ground and enjoying themselves underground, but they are suddenly silenced..."

Somewhat interesting.

Lu Qingfan pondered deeply, while Leng Hai complained resentfully in the secret door of the tea shop: "Sir, when can I come out? There is so much blood in this tea shop, I am afraid."

Lu Qingfan hummed angrily: "Just stay."

A lieutenant who licks blood from his knife and gallops on the battlefield says he is "afraid of blood"?

Do you dare to be more outrageous?

Leng Hai knew it was okay as soon as he heard the adult's tone, and got out of the secret door with a playful smile.

"Sir, my subordinate is back." Leng Chuan's voice came from outside the tea room curtain.

Lu Qingfan walked out quickly, followed closely by Leng Hai.

From the time I arrived at the tea shop and discovered the tragedy in the afternoon, to the time Yun Xi finished the autopsy, it was already sunset outside.

Yun Xi washed her hands with the water brought by Qing Guo. The beautiful peach blossoms couldn't help but observe the several extra servants around the tea shop, and asked in a low voice: "Are these the helpers invited by Mr. Lu?"

"Brother Chuan said he was transferred by the county magistrate of Feng County." Qingguo raised his head and lowered his voice and said: "Feng County has not had many cases all year round. I heard that seven people died in the tea shop at once, which frightened the county magistrate.

.”

Yes, anyone else would be frightened for a while if such a big case happened in their jurisdiction, let alone Fengxian County, which has always been peaceful.

Yun Xi wiped her hands, applied homemade hand ointment, and asked in a low voice: "Where is Mr. Lu?"

"I almost forgot, Master Lu, he said to wait for the young lady in the underground secret room." Qingguo hurriedly poured out the water for washing hands, took the small notebook recording the autopsy, and went to the secret room with the young lady.

The black hole in the wasteland was like a big mouth on the ground. Yunxi circled around the iron cover before walking down with Qingguo holding a lantern.

The master and servant followed the trajectory that Lu Qingfan had explored before, and finally found the crime scene in the right-hand corridor.

"Yun Wuzuo is here." As soon as Lu Qingfan saw Yun Xi, he raised his hand to signal her to come over.

Master Yun Xi approached and saw that beside Lu Qingfan, besides the Leng brothers, there was also a short, fat, middle-aged man with a gloomy face.

Yun Xi guessed that he might be the magistrate of Feng County.

"Yun Wu performed the autopsy with great accuracy. It is thanks to her that the important case in Qingzhou was solved. Prime Minister Sun Xian may wish to listen to the conclusion of the autopsy together."

When Sun County Prime Minister heard what Lu Qingfan said, he couldn't help but admire Yun Xi and cupped his hands and said: "I have heard that a heroine-like female widow appeared in the execution ground and solved the Qingzhou case with her own efforts. I guess it was Yunxi."

"I don't dare take it seriously. The investigation of the case is all due to the merits of the prosecutor. The civilian daughter just acted according to the plan." Yun Xi said a few words modestly and then went directly to the topic.

"Man A, his son Shinv's throat was cut with a knife, and the food in her abdomen was not completely destroyed, so she died at the earliest moment. Immediately afterwards, the murderer killed Choushinv with a knife, and after a struggle with the remaining four people, he killed five people.

My stomach is empty and I haven’t eaten.”

Of the seven deceased, two died from having their throats cut, one died from internal organ rupture and blood loss, and the remaining four died from trauma and blood loss.

The two groups of people died less than half a cup of tea apart.

"The seven deceased were all killed by knife wounds. The shape of the knife is as shown in the picture." Yun Xi said, and Qingguo cooperated and took out the picture of the murder weapon.

Lu Qingfan and his entourage came forward to watch.

Leng Hai said in surprise: "Double swords?"

"Yes, they are the kind of double swords that are as thin as cicada wings, and can cut through iron as hard as mud after exerting internal strength." Yun Xi nodded: "The murderer's right hand is strong, but his left hand is weak. The two swords were used at the same time, leaving traces on the body of the deceased.

The wounds were of different depths, so they looked bloody and messy, making people mistakenly think that the murderer was a joint attack by multiple people."

Judging from the force and marks of the sword, it was one person with two swords.

"The murderer is a master." Lu Qingfan concluded.

Within half a cup of tea, they first killed Mr. A and his wife, who had no power to fight back, and then killed the people in the tea shop. They also arranged the bodies of Mr. and Mrs. A in the way they saw them when they came, which shows the high level of martial arts on the other side.

, moves quickly and violently.

At this time, let alone the Leng brothers, Sun Xiancheng's expression was a little unclear.

"Is there any problem?" Yun Xi tilted her head in confusion.

"It's not Miss Yun's problem. These two swords make good swordsmen famous in our Ming Dynasty." Leng Hai scratched his head and looked at his master. Seeing that he didn't stop him, he continued to explain:

"There is a sect in the world called the 'Double Sword Sect', which specializes in training dual swordsmen to perform chivalry and justice. It is said that the master of the sect is an expert in using dual swords. In addition...it is said that there is also an anonymous double swordsman beside His Highness the Xian King.

"

Whether the murderer of these seven people is involved in Jianghu sects or His Highness the Wise King, solving the case will become complicated and difficult.

For a moment, everyone was silent.

"No matter how difficult it is, we must solve the case."

Lu Qingfan was the first to break the silence: "Let's take a look at the criminal's movement first: Man A and Shi Nv were dining in a secret room. During this period, the criminal broke in and attacked and killed people from behind without disturbing the tea shop above. The criminal came carrying the bodies of the two.

He went to the steps to listen to what was going on inside the teahouse. When he went out quietly, he collided with Chou Shinv who was preparing the meal and killed her with a knife. Then he fought with four people B, C, D and E and took his life."
