Yang Qiuchi asked Nangong Xiong to enter the warehouse and took out the replaced iron fence in the corner of the wall and placed it on the ground. He walked over and squatted down, waved to Kang Huai, and Kang Huai also came over and squatted down. Yang Qiuchi pointed to the broken iron fence on the iron frame: "Sir, please look, what does this broken hole mean?"

Kang Huai carefully identified it and found that there were many thin saw marks in the front and back directions on the fracture. He didn't see any name, so he shook his head.

"The saw marks on the fracture are from left to right," Yang Qiuchi pointed to the outside of the fracture again. "Sir, please pay attention to this. The last connection point is not broken. That is to say, after the lower end is sawed, when the upper end of the saw is about to be sawed, the thief did not continue to saw it, and broke it with force for twenty years. This is enough to prove that the thief saw it from right to left."

Kang Huai looked carefully and nodded: "Yes, Lord Yang is right."

"But we are relieved to see now that we are from the inside of the iron window, from the inside, from right to left, but the thief comes in from the outside, so, from the outside of the window, the saw is from left to right."

Kang Huai lifted the window with difficulty, turned it over and looked at it, nodded: "Yes, it's from left to right."

"If this is the case, it means that the whole person is left-handed."

"Yes," Kang Huai said excitedly, "only left-handed people can complete this action."

"However, left-handed people are very rare on weekdays because they are often laughed at."

"Yes, I remember when I was a child, I used my left hand to eat, and I was beaten by my father." Kang Huai said embarrassedly.

"So, this person is probably not a left-handed." Yang Qiuchi smiled.

"No, if you use a right-hand saw, you can't see it from left to right."

"So, this man saw it from inside!"

Ah! Kang Huai exclaimed in a low voice. After thinking about it, his eyes lit up: "So you suspect that the guards and robbed the fence from inside?"

"Yes! The guards who robbed themselves saw it from the inside. They would not saw the five railings when they were almost cut. If they didn't look up carefully, they would not find that the railing was almost cut off. When needed, they would break it."

"It makes sense!" Kang Huai said.

"After entering the Yunnan territory, I found that it was rainy and rainy here in winter. Therefore, these iron ground fractures are prone to rust," Yang Qiuchi pointed at the fractures. "Please look, these fractures are different in the old and new levels. Some have rusted, while others are relatively new. This means that these fractures were not sawed at the same time."

Yang Qiuchi's analysis made Kang Huai nod and said yes, but hesitated for a while, and asked: "Is it really the left hand to join the thief?"

Yang Qiuchi nodded: "There is this possibility. Then let's think about it from this perspective. If the thief wants to come in from outside, there are two possibilities: it must be from the roof, and one is from the bottom."

"The roof of the Yinkuan is tilted. The eaves are protruding very long, so it is difficult for thieves to reach the windows if they have to come down from the roof. They have to avoid the night patrols. It will be very troublesome to go up and down from the roof. At the same time, repeated up and down will leave traces of rope friction on the eaves, but I just noticed the eaves. No traces of friction were found, so it can be ruled out that the thieves saw the windows from the roof."

"Then there is only one possibility left. Grab the iron fence with your flying claws and climb up to see. The adults said that the patrol road would come almost every half hour at night. If the upper and lower sections of these five iron fences have to be cut off, it would take at least two hours. Therefore, the thief needs to avoid the patrol of the night. In other words, he can only saw for a while, and when the claws come, he will come down to hide. After the claws are gone, he will climb up to see them. This will be repeated many times and intermittently.

"If this is the case, the thief should leave more footprints on the wall. However," Yang Qiuchi stood up and pointed to the few shallow shoe prints on the wall. "Please look, judging from the action route of the shoe prints left on the wall, it is obviously only left behind by the up and down for a while."

Kang Huai stepped forward and identified it carefully, nodded repeatedly.

Yang Qiuchi pointed to the small ventilation window again: "After the ventilation window sawing the five iron fences, it was just enough for one person to barely enter and exit, which was very difficult. If a fatter person was probably unable to enter. Therefore, if the thief stole the silver from this window, he would not be able to carry it out on his back. The biggest possibility is to wrap the silver into one or several packs, and then crawl out by himself."

Yang Qiuchi pointed to the grass under the window and said, "Please look at this grass again, Lord Kang," Yang Qiuchi jumped in place and stomped the ground with his heels, then moved away, pointed to the shallow footprints on the grass, and said, "Even if the two thousand taels of silver are divided into several packs, thrown down from such a high-level window, one or several pits will definitely be left on the grass."

Kang Huai already understood what Yang Qiuchi meant, squatted down and carefully looked at the grass under the air window, then stood up and shook his head: "The grass is very flat, there is no obvious pit."

"Yes! This further shows that it is impossible to steal Kuyin from the transom."

Hearing the analysis of the two of them, the guard was as pale as if he was sifted.

"Let's go to the warehouse to take a look." Yang Qiuchi said to Kang Huai.

The two entered the warehouse, walked through a row of shelves of silver boxes, and came to the underside of the air window. Yang Qiuchi pointed to the wall below the air window: "Did you notice it? What are the traces on this wall?"

Kang Huai leaned over and looked carefully, and said, "I have observed carefully before. There are two lines of footprints, which should be left by the thief's upper and lower breath windows."

"What about these two rows of shoe prints?" Yang Qiuchi asked.

Kang Huai went up to observe carefully, took a step back and looked at it, shook his head: "There is no trace anymore."

"That's right!" Yang Qiuchi said with a smile, "Since the thief climbed in through the air window and left only two lines of footprints, it means that the thief only went up and down once. However, he stole two thousand taels of silver. If he wrapped the silver into a bag and climbed up along the rope, the silver would be too heavy and would be very tiring and inconvenient to enter and exit. If it were an adult, what would you do?"

Kang Huai thought for a while and said, "Of course, he put the silver on the ground, tied the bag of silver with a rope, then climbed up the window, turned it out and rode it on it, dragged the silver on it, and then grabbed the remaining iron fence, and threw the bag of silver outside."

"Yes! The two thousand taels of silver are too heavy to wrap in one bag. I'm afraid there is nothing unexpected that can withstand such a heavy weight. Therefore, the best way is to wrap the silver bill into several bags, prepare a few more ropes to tie them up, and pull them up separately, which saves labor and is convenient."

Kang Huai nodded. Yang Qiuchi's analysis made sense, but he didn't understand what Yang Qiuchi's analysis should explain.

Yang Qiuchi pointed to the wall and said, "If so, since these are all saddle-shaped silver ingots, they have edges and corners, even if they are wrapped in Brie, these silver bags will leave traces of dragging on the wall."

Kang Huai suddenly realized: "There are no traces on the wall, which further shows that the silver was not stolen from the ventilator at all. These are all illusions created by someone on purpose!"

Yang Qiuchi nodded: "If you want to steal the silver from this impregnable silver treasury, if you don't steal it out of the air window and there are no traces of digging holes and walls in the room, there is only one possibility, go out from the gate! It is impossible for outsiders to deliberately forge these traces in the warehouse, and only guards have this opportunity!"

"The keys are kept separately by two people. Without any one, it is impossible to open the silver vault. Moreover, it takes a long time to cut off the iron fence and forge the scene. It is also impossible for one of the guards to hide the other guards. Therefore, only if the two guards conspire to complete the conspiracy of custody."

"Mr. Kang just said that guards rotate once a day, and they have to count the treasury and silver to hand over the shift every time. Therefore, they can only do it when they are on duty."

Yang Qiuchi walked back to the rotten window on the ground, looked at the sawed iron fences, picked up one, handed it to Kang Huai, and said, "There is blood on this iron fence, so you can smell it."

The iron railing was already rusted and the blood had been covered by rust. So Kang Huai looked carefully and found no blood on it. He took it under his nose and smelled it. Sure enough, there was a faint smell of blood.

Yang Qiuchi said: "This should be the scene of the guard forgery. When the iron fence was cut off, a sharp broken cut cut into the palm of the hand. The guard used his wounded hand to grab the iron railing, so the blood was left on it. I found that there was a lot of blood on the iron railing. I guess the man's wound should be deep and will not heal in a short time. So checking their palms, one of the guards' palms was indeed injured, which determined the suspect."

After Yang Qiuchi finished speaking, he walked to the two guards and asked, "How is it? What else do you have to say?" The two guards were already limp on the ground with no face.

Song Yuner kept following An An and listened to them quietly, and at this moment she finally couldn't help but praise: "Brother, you are so awesome, you can see it at a glance."

Yang Qiuchi smiled: "Didn't I say that any crime will leave traces, it depends on whether you can discover it."

Kang Huai praised: "Mr. Yang said it well!" He walked over and stared at the two guards, and asked fiercely: "Are you taking it yourself or is this official punishing?"

The two knelt down and kowtowed: "We've called us, please spare your life!"
