After I arrived at Master Qiangu, Yang Qiuchi asked, "Master, how do you usually deal with the cinders in these smelting workshops near our Ningguo Mansion?"

How else can I deal with it? In ancient times, there were not as many environmental pollution problems as it is now, so there were no strict regulations on the emission of the "three wastes". Master Qian Gu didn't know why Yang Qiuchi asked this question. After thinking about it, he said, "It is usually piled up next to the smelting workshop at will."

If this is the case, it would be meaningless. Yang Qiuchi didn't give up and asked with the last hope: "Is there any other place to pull this cinder away from waste or use it?"

Master Qian Gu thought Yang Qiuchi's problem was ridiculous, but Yang Qiuchi was a distinguished guest of Master Zhou's official. How dare he laugh, he still couldn't help laughing: "Sir, you said this is a waste, how can this waste be used?" However, there was no such thing as cinder waste at that time.

Hou Xiaoqi behind Yang Qiuchi said, "Young Master, I know that the Jinyiwei and Ningguo Mansion guards often use cinders to train the grounds."

"Really?" Yang Qiuchi asked in surprise, "How do you know?" Then he immediately remembered that Hou Xiaoqi himself was Xiaoqi of the Jinyiwei Hundred Houses Office of Ningguo Mansion. He must have been to the training grounds of the Thousand Houses Office of Ningguo Mansion Guarding Army. He immediately changed his words and asked, "What are they doing with the drill grounds of the cinders shop?"

"If it is not covered, the next heavy rain will be wet and slippery on the playground, and it will be full of mud. It will not be able to practice for several days. The cinder absorbs water. After being covered, even if it rains heavily, it will not be muddy."

"So that's it," Yang Qiuchi suddenly realized, "Do you know where else is used to lay the floor with cinder?"

Hou Xiaoqi thought for a while and said, "Except for the drilling grounds of the Jinyiwei Hundred Houses Office and the Thousand Houses Office of the Army, there is no cinder in other places." After a pause, he added, "Although this cinder can absorb water, it looks dirty and messy, and others don't like it. The young man often runs around Ningguo Mansion. He has never seen other places use cinder to lay the floor."

So, the last hope now is the Jinyiwei and the Thousand Houses of the Army. But when you think of these two places, Yang Qiuchi is too big, and the total number of soldiers in these two places is several thousand. If you want to compare one by one, it will be better than going to the year of the Monkey and Horse Month.

Yang Qiuchi frowned and thought about how to narrow the scope.

In the army, Yang Qiuchi didn’t deal much with the army in modern society. When he was in college, there was a military barracks behind the school. When he first entered college, he liked to recognize his fellow villagers and once went to play with fellow villagers. However, the system in the army was very strict. Soldiers need to approve leave when going out, and there are quotas and time limits. They are definitely not allowed to run out casually.

Yes! Yang Qiuchi suddenly thought that since the military system is strict and he cannot go out at will, check the people who go out during the murder period and then compare them. Isn’t that enough? Haha! Yang Qiuchi is happy again. Now that the social army is strictly managed, I don’t know whether the Ming Dynasty’s army is strict or not.

Yang Qiuchi asked Hou Xiaoqi: "Do you know if the Jinyiwei Hundred Houses Office and the Military Thousand Houses Office need approval to go out?"

"There is a need for land," said Hou Xiaoqi, "and it is very strict in management. Besides, it is already the slack season in winter. The soldiers in the military households are concentrated in the Thousand Houses for drills. There are many people. If the management is not strict and they run around, there will be no way to train."

"Why do you need to register when going out?"

"Of course, you have to register. All soldiers who go out, including the Jinyiwei of the Hundred Houses, must be approved and registered when going out privately. If they come back after more than the time, they will be blocked."

Ha, it seems that the management of the Ming Dynasty's army is also very strict, very similar to the current army, so it's easy to deal with. Yang Qiuchi said happily: "Let's go to the Jinyiwei Yamen." Yang Qiuchi decided to start from the Jinyiwei Hundred Houses, and there were relatively fewer people here.

Niu Baihu was very happy to see Yang Qiuchi. After hearing Yang Qiuchi's intention, he immediately sent someone to call the sergeant who was in charge of leaving for leave and got the registration book of the Jinyiwei who asked for leave for private matters during this period. Yang Qiuchi turned over the murder period and went out for the two days. Fortunately, there were not many private matters in the past two days, only six. It seems that the management of Niu Baihu is still very strict.

Yang Qiuchi asked Niu Baihu to call the six people, extract their fingerprints, and then found a room to compare them quietly. As a result, no one was found. Yang Qiuchi was disappointed but a little relieved. He was the commander-in-chief of the Jinyiwei, so he definitely did not want to see the Jinyiwei people commit such a thing.

When Niu Baihu heard that Yang Qiuchi was going to investigate the case in the Qianhu Institute of the Army, Niu Baihu was very familiar with Gao Qianhu, the highest leader of the Qianhu Institute of the Ningguo Mansion, so he volunteered to accompany Yang Qiuchi, which was in line with Yang Qiuchi's wishes.

The group immediately rushed to Qianhu Institution. Sure enough, they saw that the drill field in Qianhu Institution was covered with cinders.

Gao Qianhu also heard the story of Yang Qiuchi, a young prisoner, who solved strange cases during the period of time, and had heard of Yang Qiuchi. In addition, the introduction of Niu Baihu, the Jinyiwei, was very polite to Yang Qiuchi. Yang Qiuchi checked the registration book of the military personnel of the Qianhu Office during the murder, and there were nineteen people. After Gao Qianhu called these nineteen people, Yang Qiuchi extracted his fingerprints and compared them. As a result, he was disappointed again, and none of them matched them.

It's over, all the clues are interrupted, what should I do?

Gao Qianhu was very hospitable and insisted on keeping Yang Qiuchi and others for dinner. Anyway, the clues were broken and there was nothing to do. Song Qing and the others did not come back, so Yang Qiuchi and Song Yuner stayed for dinner.

Although she looked depressed, after drinking a few cups of wine, Yang Qiuchi gradually became happy. Seeing that Yang Qiuchi was in a better mood, Song Yuner was also very happy. After drinking a few cups with Yang Qiuchi, her face turned red.

After eating and drinking, Yang Qiuchi and others were about to say goodbye. A soldier ran into the outside and reported that several soldiers from the Ministry of War of Yingtian Prefecture had come to Ningguo Mansion on a business trip and asked the Qianhu to go to greet him quickly.

Yang Qiuchi felt aroused in his heart and asked Gao Qianhu: "Does people from other places often come to our Qianhu office?"

Gao Qianhu said: "That's not the case. It's mainly the men of the Yingtian Prefecture War Department in the capital, and there are also the soldiers of the Beijing camp and the personal military guards of the Protectorate's Office sometimes come down for official duties."

"Then, have you been here in the past few days?" Yang Qiuchi's heart began to be beating, which was his last hope. For a moment, his heartbeat increased faster, and even his mouth became dry.

"Yes, I just left yesterday." Gao Qianhu replied, "It was from Yingtian Prefecture Jingying, with three people in total."

"Is there anyone else who has come to work in business?"

Gao Qianhu smiled and said, "In the cold winter, who is willing to go on a business trip? This group has been in this month, and the wave that has just arrived, there are only two groups of people."

"Do they need registration approval when going out?" Yang Qiuchi asked anxiously.

"Hehe, Mr. Yang was joking. They were sent by the superiors, and they were not under our jurisdiction. They were all free from entering and leaving. How dare we let others report and register. The group that just left has been staying for a long time. The big thing was done in half a day, but they were stunned for almost half a month before leaving. I saw that they ran to me to hide from the errands. Hehehe."

Yang Qiuchi's heart suddenly lit up, hoping that it was in this group. If his judgment was correct, the biggest suspicion would be this group!

Yang Qiuchi asked, "What are their names? Who sent them? Where did they live? Are the things they used still there? Can they find them now?"

A series of problems left Gao Qianhu unable to deal with it for a while. After thinking about it, he said, "A leader named Deng Youlu. I didn't ask the names of two subordinates, but I can find it. Deng Youlu is a general under Bai Qian, the fourth guard and the third thousand household in the Jingying Camp of Yingtian Prefecture. The thing they used should still be there." This general is always the deputy of Qianhu, who was the sixth rank of the Ming Dynasty.

Mr. Bai Qian’s subordinates? There are so many inner guard troops in the capital, and they happen to be from the locals in Mr. Bai Qian’s inner guard troops. It’s a coincidence.

When Yang Qiuchi thought of Mr. Bai Qian, his daughter Bai Sumei's sad eyes suddenly came to his mind. He didn't know if she was good now. If this case involves Mr. Bai Qian, he might have to see her.

Now Yang Qiuchi is afraid to see Bai Sumei. He doesn't know how to face this woman he has been unintentionally forced to hurt, but he subconsciously longs to see this woman. Thinking of her soft lips and plump breasts, Yang Qiuchi couldn't help but feel a little excited. I don't know if she is married now. However, Yang Qiuchi had a premonition that this girl Bai's understanding of feudal ethics was too dogmatic. She was kissed by herself and probably wouldn't marry someone else easily.

Now is not the time to think about this question. Yang Qiuchi asked Gao Qianhu: "Sir, can you take us to see where they have lived?" I hope that if the things they have used are still there and fingerprints are left on them, they can be extracted and compared immediately.

"Okay, I'll ask someone to take you there. I have to go and greet the person. Sorry." Gao Qianhu called two soldiers to take Yang Qiuchi and others to the Qianhu Inn. The general Deng Youlu lived in a single room, and the two entourages lived in another room.

The sergeant who led the way opened the door and Yang Qiuchi entered Deng Youlu's room and found that the bedding inside had been replaced with brand new ones, and the room was neatly tidy and seemed to have been cleaned. Yang Qiuchi was very disappointed, but he did not give up. Because after Deng Zhuang left, no one had lived in the room, and no one had lived in the past half a month. After excluding the fingerprints of the people who cleaned the room, the fingerprints of the three people should be confirmed.

Yang Qiuchi asked the sergeant to call the two orderly soldiers who cleaned the room and asked them, knowing that the teacup in the room had been replaced, the bedding had been replaced, the old ones were soaked in large basins for washing, and the tables and chairs were wiped.

Yang Qiuchi smiled bitterly. It was a coincidence that he met two particularly diligent orderly soldiers.

However, Yang Qiuchi decided to check it out, especially the tables and chairs, perhaps in a corner that had not been touched, the remaining fingerprints could be found.

After careful searching, Yang Qiuchi found several fingerprints on the back of the table and chair, and asked the sergeant to bring a piece of paper and asked everyone to avoid it. Yang Qiuchi took out his magnetic fingerprint brush from his arms and gently brushed the fingerprint part. The fingerprints immediately appeared. Yang Qiuchi used tape to extract the fingerprint and pasted it on the piece of paper.

Put the fingerprint brush on, take out the cloth with bloody handprints from your arms, and conduct a preliminary comparison.

Suddenly, Yang Qiuchi's eyes widened, and one of them was the same as the fingerprint on the bloody handprint!

Found it! Yang Qiuchi was ecstatic, his hands trembled a little. He took out a magnifying glass from his arms, and carefully observed and compared it carefully. Sure enough, the fingerprint pattern and the fingerprint pattern are generally the same, and the details of the pattern line are also consistent. It is certain that it was left by the same person. The boss Deng Youlu, who is under General Bai Qian, is a major criminal suspect, is likely to be the murderer who killed Tu Laosi and silenced him!

Although she was very excited, Yang Qiuchi carefully extracted the fingerprints from the rooms where the other two entourage soldiers lived, and compared them with the bloody handprints. The results were different. Only then did she conclude that Deng Youlu was the person who left the bloody handprints on the scene.

Yang Qiuchi decided to go back and tell the news to the prefect Zhou, and then asked the prefect Zhou to send a constable to Yingtian Prefecture to immediately arrest the murderer Deng Youlu.

After saying goodbye to Gao Qianhu and Niu Baihu, Yang Qiuchi, Song Yuner and Hou Xiaoqi returned to the prefect's office.

When he entered the yamen, he saw several familiar figures from afar. It was County Magistrate Song and Yang's mother. Before he could see others clearly, a girl was already jumping and rushing into Yang Qiuchi's arms. It was Song Qing. When Song Yuner saw this scene, her face suddenly turned pale and she hid aside alone.

Although Yang Qiuchi was quite thick-skinned, he was still a little embarrassed in front of such people. He gently pushed Song Qing away, greeted Yang's mother and Magistrate Song, and then asked Song Qing: "How is it? Did you agree to break off the engagement?"

Song Qing nodded and said, "After my uncle told me about the divorce, my mother agreed immediately, but she said that the marriage was decided by my father before her death. It was indeed a bit embarrassed to break the engagement. If the Hao family is willing to break the engagement, it would be the best. My uncle said that he would break the engagement from the Hao family. As long as the Hao family agreed to break the engagement, the matter would be done."

Song Qing turned her head and looked at Magistrate Song and said gratefully: "As soon as we returned to Ningguo Mansion in the morning, we immediately went to the Hao family to discuss the divorce. My uncle was still very good at face. As soon as he said that, Mr. Hao agreed." He hugged Yang Qiuchi's neck and jumped with joy. After all, she was only sixteen years old and was just a half-year-old child.

Yang Qiuchi was very happy and thanked Magistrate Song repeatedly. He asked Song Qing again: "Then, has my mother agreed to our marriage?"

Song Qing's expression became a little dim, and she looked at Magistrate Song and said nothing.
Chapter completed!
