Li Xiuran frowned, puzzled, looked at Wu Songshan and said, "Did you find any clues?"

Wu Songshan shook his head: "It's searching, but it has not been discovered yet."

"Let's look for it." Li Xiuran said in a deep voice.

"Yes." Wu Songshan responded, turned around and became busy.

Li Xiuran came to Tang Jun's body. After the person died, his muscles would be loose, and the air would be filled with stench. He had long been used to this, so he ignored it and began to concentrate on checking the body.

The neck wound was narrow and long and deep, and it should be a sword injury. The limbs had begun to become stiff, and corpse spots appeared faintly on the face, chest and abdomen. The death time should be at least one hour. The body was lying on its side, head inward, feet towards the door, and the expression on its face was a little scared. It was basically certain that after Tang Jun met the murderer, he disappeared after meeting the murderer and had no time to run away.

There was another person next to the body, with red and swollen eyes and a sad face. He should be Tang Jun's son. However, because he wanted to protect the scene, he could not get close to him, so he could only watch from the side.

Li Xiuran looked at him and asked, "Are you the son of Teaching Yu Tang? Did you see the murderer when you came in?"

"No, I only saw my father lying on the ground, and I saw nothing else." Tang Jun's son shook his head.

Yes, you are about to see it, and now you probably won’t have a chance to stand here... Li Xiuran turned his head and looked at the teachers and students of the Fuxue School standing outside the door: “Has outsiders ever come to Fuxue School today?”

There are a bunch of weak scholars in the public schools, which are obviously cruel and ruthless. They treat human lives like grass, and the murderer should be an outsider.

A group of people looked at each other, no one answered.

Well, it’s another headless unsolved case. Why do you always encounter such a thing recently?!

Li Xiuran sighed depressedly.

"Boss, I've discovered it!"

Luo Dazhuang's surprise sound suddenly came outside the window.

Li Xiuran was excited and walked over quickly.

Luo Dazhuang pointed to the ground and said, "There is a footprint here, with blood on the door, which should be left by the murderer when he jumped out of the window."

Li Xiuran looked along Luo Dazhuang's fingers, and with the light emitted from the lantern in his hand, he saw a blood footprint clearly left on the ground.

Finally, I found out!

Li Xiuran was delighted, squatted down and carefully observed the footprints, reached out to look at them for a moment, and pondered: "The footprints are about one foot long, and the murderer should be about seven feet per inch tall.

The footprints are wide and the indentation is uneven, the edges are heavy and the middle is shallow. The murderer should be a man.”

"Can you see this?" Lin Fengkai stared beside him.

He was worried about affecting Li Xiuran's case just now, but he never dared to speak. Now he actually showed the murderer's height and even his gender with just one footprint. He was really a little overwhelmed.

Han Lu, who had been expressionless, also cast a slightly curious look at Li Xiuran, and was obviously very interested in it.

Luo Dazhuang was even more surprised when he heard this: "How did you see this... boss?"

"Usually, a person's height is about seven times the length of his feet, and due to different physical fitness, there are obvious differences in pace and footprints for men and women.

Women are relatively short in height, narrow and short in feet, low arches, less muscles and more fat, so they are low in center of gravity, small strides, and strong stability. The reaction is to the footprints that are even indented and wide in the footsteps.

Because men are relatively tall, have long and wide feet, have more muscles, less fat, and have strong bounce power, their footprints are usually uneven indented, with heavy edge marks and shallow middle marks.

If you know these, you can tell by comparing them?"

Li Xiuran glanced at the few people, with a look that you rarely see strangely.

"this……"

Lin Fengkai was speechless, lowered his head to cover up the embarrassment on his face, looked at the bloody footprints on the ground, stretched out his hand and gestured at his feet a few times, and then seemed to have discovered a new continent, and said happily:

"It's true. I'm seven feet or eight inches tall and my feet are about seven times longer."

A trace of admiration flashed across Luo Dazhuang's face: "It's better that the boss knows a lot, but... even if he knows this, what's the use."

"Of course it's useful." Li Xiuran said in a deep voice: "The document library was stolen last night, and the murder case broke out tonight, which are all related to books. The murderer is likely to be the same person.

Within one day, the murderer was able to accurately find the official school from the government office, which means that the murderer was either a city man, familiar with the terrain, or had inquired about it. No matter which one it was, if you knew this, the range of the murderer could be reduced a lot."

"Dazhuang, you immediately go back to the government office, go to the house and transfer the household registration in the city, and follow the map to search for all the seven-foot-one-inch male men above for me to check.

Remember, the murderer is cruel and ruthless, and is likely to be a monk, and he uses swords as weapons to make his brothers be careful.

Even if you can't find the murderer, you have to create the momentum for me, the bigger the better."

Li Xiuran looked at Luo Dazhuang and instructed in a deep voice.

There are household registrations in this world. Although the information recorded is not as comprehensive as that of later generations, there are still some main characteristics, and height and gender are the two of them.

"Don't worry, boss, I will do it for you." Luo Dazhuang responded, turned around and walked outside the palace school.

"Boss, where are me?" Wu Songshan was eager to try.

"Don't worry, I can't forget you."

Li Xiuran smiled and narrowed his eyes and said, "If what I expected is good, if the murderer is a city man, he will definitely be able to find him out according to his household registration.

If the murderer is not a city man, he will definitely alarm him under the big and strong search, and then he will most likely choose to escape because of disturbance.

You take someone and I to the city gate to wait for the rabbit to prevent the murderer from absconding."

Wu Songshan was excited and smiled and said, "Yes, the boss is still thinking attentively."

Li Xiuran turned to look at Lin Fengkai: "Brother Lin, you..."

"I'll go with you." Before Li Xiuran finished speaking, Lin Fengkai said directly, with a faint expression of excitement.

Then I'm so eager... Li Xiuran was very calm in his heart. The murderer was cruel and ruthless, and he didn't know his specific cultivation. With Han Lu, a master of the spiritual realm, accompanying him, at least the safety is more guaranteed.

I looked at the sky and it was already midnight when I received the notice. It took me a lot of time to travel and survey. Now it has been five o'clock.

The Huyan Empire opens the city gate at 5:00 a.m. every day, and there is a distance from here to the city gate, so there is not much time left for them.

Li Xiuran said decisively: "Since that's the case, let's set off immediately. The city gate will be opened soon. Don't go too late, so let the murderer take the opportunity to escape."

"good."
