When Guan Chang returned to the Invincible Sect, he also brought back a box of gold ingots, and the project of the first phase of the Duanwang Mansion cost a total of 4,700 taels of silver. Therefore, after obtaining the permission of King Duan, Steward Yang proposed to pay the bill with gold.

Guan Chang knew that there was a special place for storing silver, and every once in a while, someone would transfer the silver to the Invincible Sect and store it in the treasury. He was speechless about this backward way of saving, and metal money was prone to oxidation and moisture, and it would only depreciate if it was in his hands. The silver is slightly better, but the copper coins are particularly miserable, even if they are stored well, half of them will be lost every year.

"I've seen the senior brother in charge!"

As soon as he entered the Invincible Sect, he saw Song Xiong come out.

"Senior brother, you're back! Where is your senior sister?" Guan Chang's face was happy, since Song Xiong came back safe and sound, it means that this trip to Beijing was very smooth.

"Well, it's back. The trip went very smoothly, and the senior sister entertained Ping Catcher inside. Song Xiong replied.

Guan Chang pointed to the wooden box on the carriage behind him and said, "You keep this box of gold, and I'll go to see Ping Zhutou." ”

......

Ping Taolai Invincible Sect was invited by Guan Chang to explain the investigation case to the inner disciples, and secondly, he reported the progress of the murder case of Xie Yun'er's family with Guan Chang and others.

Ping Tao had repeatedly verified the events of the day from Xie Yun'er a few days ago, trying not to miss any details. He even ignored Guan Chang's opposition and "acted" with Xie Yuner once, which made Xie Yuner cry so much.

He didn't go to the exploration site as soon as possible, because the matter was not reported to the official, and Xie Yun'er's whereabouts were not even exposed. He was afraid of leaving traces at the scene of the crime or encountering the thief's eyeliner, which would arouse the thief's suspicion and vigilance.

However, he affirmed the investigation ideas of Guan Chang, Song Xiong and others, and followed the clues of Xie Yun'er's new house. After he integrated all the clues, he and Wang Qihe, Tang Da, and Xie Yun'er disguised themselves as merchants and went to Xiafengkou, where the crime occurred, to investigate.

Ping Tao deserves to be arrested, and even after a few months, he can still find useful evidence. Although this evidence has been fragmented, it can be connected with some previous reasoning to make the whole case clearer.

In the living room, there were only Guan Chang, Ping Tao, Liguan Bai, Wang Qihe, and Song Xiong, who had just returned from saving gold.

I only heard Ping Tao say to everyone: "There are three suspicious points in this case itself, one is the motive, the second is the murder weapon, and the third is the aftermath. ”

Ping Tao thought that the motive of the gangsters was to rob and kill the habitual criminals they had guessed before, but the suspicious thing was that the massacre of this scale must be very organized and disciplined. The case was clean and neat, and there was no mud and water except for Xie Yun'er escaping. And Xie Yun'er's danger is also caused by her parents' impatience and her forbearance that is different from ordinary people.

Ping Tao even thought that Xie Yun'er's father, Xie Zhiyan, had already entered this mortal situation when he changed his house! Perhaps when Xie Yun'er's father made his fortune, some of the gangsters had already lurked beside him. This person gained Xie Zhiyan's trust, set a trap step by step, and let him move his family to Tan County!

This matter is not groundless speculation, but the result of Pingtao's research. He originally wanted to secretly visit some people who traveled back and forth between Yong'an County and Tan County, and ask them if they had passed by Xiafengkou in the past few days. Only then did he know that the side of Xiafengkou was no longer the only way from Yongan County to Tan County. Nowadays, most people choose another road, which has shortened the journey due to a new stone bridge. This has led to the inaccessibility of the Xiafengkou side, and Xie Zhiyan can't be reluctant to go far as a businessman, the only reason is that someone persuaded him to take this road!

No murder weapon was found at the scene of the crime, but Ping Tao found arrows with arrows left on the trees. Presumably, the villains also cleaned up the scene, but the arrow was too deep into the wood to pull out, so the arrow was simply broken. If you don't look closely, you won't notice this arrow.

Ping Tao judged by the material and shape of the arrow that the arrow actually came from the army. And not the arrows of ordinary bows and arrows, but the arrows of crossbows. Judging from the angle and strength of the wood, it is also shot from a crossbow rather than a bow.

Ye Guo's control over crossbow arrows is very strict, and it is absolutely impossible for ordinary people to come into contact with crossbow arrows. How the perpetrators got the crossbow arrows is also a big doubt.

Ping Tao has two guesses about this. First, the perpetrator was a military household, and he stole crossbow arrows during the annual military defense camp training. Second, the perpetrator obtained the crossbow arrows eliminated from the armory through special channels.

The last point of suspicion is the aftermath of the crime. The scene was cleaned up almost perfectly, and Ping Tao believed that there was no second person in Ye Guo who could find clues besides himself. This well-trained technique made Ping Tao shudder, which is enough to prove that this case is definitely not a first-time offense!

Ping Tao contacted the file in his hand again—there had been three bizarre cases of the disappearance of entire families in Xiting Mansion before.

Only the first of the three incidents was reported seven days after the incident, and the other two cases were reported more than a month later.

The victims of several cases have one thing in common, that is, the entire family has been relocated! Other than that, there is no way to investigate these cases!

Ping Tao thought that it was the same group of people who committed these crimes! And the case of Xie Yun'er's family will be the key to solving the serial robbery and murder case, because this is the only case in which there are survivors!

Liguan Bai was a little disappointed when she heard Ping Tao's analysis of the case, and she said stupidly: "You have been talking for a long time, and it is not that you have not solved the case!

Guan Chang persuaded with an embarrassed face, "Senior sister, you listen to what Ping Zhutou has said." I guess he's got a plan!"

Ping Tao said apologetically: "This case is indeed complicated, and I also want to find out the real culprit as soon as possible." But they are professional ...... after all."

Li Guanbai suddenly became sensitive, and said, "Who do you say is unprofessional!"

Guan Chang blinked, why was his junior sister's focus so peculiar.

Ping Tao hurriedly said, "After listening to me, although I haven't solved the case yet, I have already set my sights on some people in Tan County!"

Wang Qihe asked curiously: "But those gangsters who pretend to be bandits, are there any suspects?"

Song Xiong said calmly, "It should be those old servants who participate in housing transactions or guard houses." "He had secretly visited and investigated these people before, but unfortunately he had gained very little.

Ping Tao nodded, but shook his head again, "The suspects are indeed suspicious, but they are in the shadows." There are many people who handle it in the middle, and it is difficult to find useful information. I sorted the three cases in order of occurrence and found that the second and third cases were all from the same county, with an interval of about half a year. What does that mean?"

Guan Chang suddenly said, "It means that they will continue to commit crimes in the same place, either because they just have a goal, or because it is quite troublesome to turn around to other counties, so they will simply do it together." And it takes about half a year to prepare for one?"

Ping Tao said, "What Guan Zhangmen said is right. Therefore, the people I am eyeing are the ones in Yongan County and Tan County who may be selected as targets!"

Guan Chang secretly said, this is empathy! Ping Tao imagines himself as a gangster, and then searches for targets in Tan County! If the gangster is really a habitual offender, then he will follow a certain habit of committing a crime again; after all, the cost of this kind of group crime is high, and the discipline and regularity will be stronger! As long as we keep an eye on those possible victims, we are not afraid that the gangsters will not show their feet!

Guan Chang arched his hand and praised, "The blood-faced god catches the name!"
