"Ah."
Pushing the issue
Li Qingcha could only give it a try.
She waved to Gong Lianxue,
"Lianxue, the most important thing now is to find the source of the fire. Please help me."
"Tell me how you want me to help you."
"That should be... ah, I got it. Look there. Can you see the end line of the burning spread?"
"Ah."
"Not only the termination line, but also the smoke marks and the damage to the items are helpful in determining the starting point of the fire."
These are the most basic knowledge. Even a detective, who has not received modern education, knows how to make directional judgments.
But the problem now is...
"Those were left behind by Master when he put out the fire."
"..."
Li Qingcha was speechless.
When facing a fire, the issue of fire cause identification is generally not considered, because extinguishing the fire and saving lives as soon as possible and preventing re-ignition are the top priorities.
However, by chance,
The one who put out the fire was Gong Yihan, a second-rank monk;
The way to put out the fire is to pump water directly from the lake and pour it down in the form of a waterfall.
In this case, even if the end line, smoke marks, and damaged items can be seen, they are of no reference value to a novice like Li Qingcha who is good at fire scene investigation.
Li Qingcha raised his eyebrows slightly.
Just now, Gong Yihan's attitude change was very interesting. It was probably because he knew it was difficult to investigate.
Knowing that it would be difficult to investigate, you dissuaded Xiang Nanyu?
Or, knowing that it would be difficult to investigate, he instead involved Li Qingcha to silence Xiang Nanyu?
Or both?
tsk...
Li Qingcha was secretly shocked.
These things are even more troublesome than the arguments in the temple...
Forget it, destroy it quickly.
Li Qingcha decided to give up and sighed in a depressed manner.
"Ahem... Sect Master, Junior Sister Xiang, this matter is really beyond my ability, so..."
She had a harmless smile on her face.

Even the omnipotent Li Qingcha has times when he admits he is not good enough.
As a victim, Xiang Nanyu felt angry, but also wanted to laugh for no reason.
She complained: "Brother, you did it on purpose."
Use declarative tone.
Li Qingcha nodded.
"Yeah, I did it on purpose."
He also used a declarative tone and did not forget to spread his hands after he finished speaking.
Xiang Nanyu was dissatisfied and snorted softly.
At this time,
"Brother, come and see!"
Gong Lianxue's voice sounded, with a hint of excitement.
Li Qingcha: ￣□￣｜｜
I had already started, but at this moment I discovered...
She looked depressed and leaned over.
"what happened?"
"Look!" Gong Lianxue pointed at the ground, "This should be a footprint."
"It's normal to have footprints..."
"Brother, your attitude is so perfunctory."
The girl pinched the soft flesh on Li Qingcha's waist.
Li Qingcha had no choice but to squat down and check carefully.
There were a group of footprints just outside the fire scene, intermittently, but because most of them were covered with dust and washed by water, they were not very complete, and only three of them could be seen.
She used her right index finger and thumb as a ruler to measure the length of the footprint.
Gong Yihan looked over curiously.
She knew that Li Qingcha had solved several cases in the capital, including a major case involving a demon clan spy. If what she said was true, then Li Qingcha was a man who could judge the Yang during the day and the Yin at night.
but,
"It looks no different from what ordinary people do when they investigate~" Gong Yihan said.
"Master, you don't understand this," Gong Lianxue retorted, "My senior brother said, 'check the scene a hundred times'. This is the basic principle of criminal investigation."
"..."
"What's wrong, Master?"
Gong Yihan shook his head, indicating that it was nothing.
However, he was complaining in his heart that his disciple had turned into Li Qingcha's shape.
At this time, Li Qingcha was still investigating.
She first compared it with her own feet, then tried stepping on the dust beside it, and whispered, "The person who left this footprint was probably about the same height as Lianxue, but with narrower shoulders."
Gong Lianxue was already used to Li Qingcha's magic, but Gong Yihan had never seen it before.
"How do you know?" she asked in surprise.
"It's calculated based on the footprints," Li Qingcha replied. "The length of the footprints is proportional to the height of the person... well, there is a clear ratio."
"is it?"
"The Sect Master can let the disciples in the sect give it a try. There is a 99% chance that they will not be able to escape."
“Is the ratio the same for men and women?”
"Different."
"Then you used your feet to measure just now. Was your calculation accurate?"
"..."
Li Qingcha was speechless.
We are both women, how can the calculation be inaccurate?
She coughed awkwardly and changed the subject: "This set of footprints was not left after the incident. After the fire was put out just now, a few footprints were able to remain intact around the fire scene, which means they must have been stained by something..."
He stopped talking suddenly in the middle of his words.
Gong Lianxue immediately asked: "Brother, did you find anything?"
Li Qingcha nodded, frowning.
"What's wrong?" Gong Yihan asked.
"I may know the characteristics of the criminal." Li Qingcha pointed to the ground and said, "Look at this pair of footprints, and then look at the ones I just left. What's the difference?"
Everyone was surprised.
Perhaps, the relationship between footprints and height, weight and body shape may be mentioned in criminal books, but it is impossible to judge the identity of a suspect based on footprints.
Gong Lianxue whispered, "Brother, don't keep me in suspense."
Li Qingcha said: "Look, this pair of footprints, the right one is deep and the left one is light, which means that this person had a sprain when he left the footprints."
"Brother, the monk is sprained..."
"Yes, that makes sense. The assumption that the monk had a sprain is unrealistic. If it is not a sprain, then it means it is a deformity, which is what we often call uneven feet."
"..."
Gong Lianxue fell into deep thought.
Gong Yihan took over the conversation and said, "Qingcha, all the disciples of the Moon Sect practice the Heavenly Demon Soul-Stirring Dance, which places great emphasis on balance and high and low kicks. They simply do not have the conditions for practice, so..."
Gong Yihan didn't say the following words, but everyone understood.
If the prisoner really has high and low feet, then he must not be a member of the Yue Sect.
Li Qingcha was in deep thought.
There is definitely a reason why the footprints are deeper on the right and lighter on the left.
She whispered, "People's feet are mostly the same shape, at most the arches may be slightly different. However, as lifestyle habits develop, over the years, there will still be changes."
Gong Lianxue asked: "Brother, can you give me an example?"
"Well... let's take the pharmacy clerk as an example. The pharmacy has a device for pounding medicine. The foot steps on one end of the pedal, and the other end is a mortar and a hammer. The clerk keeps stepping on the pedal to make the hammer fall, crushing the herbs in the mortar."
"So what?"
"Many guys have been helping out in pharmacies since they were young. When they were young, they were small and short, so when they stepped on the pedals, they used more force with the forefoot than with the back of the foot. Over time, this formed a habit, which resulted in their footprints being deeper in the front and shallower in the back.
"..."
Gong Lianxue seemed to be thinking about something.
Li Qingcha added: "In fact, when people run, their footprints are also deep in front and shallow in the back, but the pharmacy guy only has one foot like this, so he can still distinguish the two."
One footprint has so many doors.
Everyone admired Li Qingcha.
However, admiration is useless, the criminal must be caught.
Li Qingcha squatted there, staring at the footprints.
There is no unevenness in the feet and the injury is not sprained, so it seems that the only possibility is that the crime was committed by an outsider.
She stood up, brushing off the dirt on her hands, and said, "It's too weak to judge based on the footprints alone. Perhaps, only if we find out the source of the explosion can we get something."
Unfortunately, the site was badly damaged by the "waterfall", making it impossible for non-professionals to work on it.
Gong Yihan said: "Qingcha, how about I ask everyone to leave footprints for comparison?"
This move was purely to shut Xiang Nanyu up.
Li Qingcha said nothing.
Gong Lianxue who was standing by suddenly spoke up: "Brother, could beriberi cause this condition?"
Li Qingcha: ...
beriberi?
She coughed lightly,
