According to Sun Ting's analysis, whether the Liao couple was harmed by Dai Jinshuang has a lot to do with whether the two of them had been in the "Caichi Pool". If the two of them had never been in the past, then Dai Jinshuang would be suspected of committing the crime, but on the contrary, it means that the murderer is likely to have someone else. At this point, whether the couple had been in the "Caichi Pool" became the key to the murder. According to Alxun, as long as the passport of Liao couple had traces of water, it proved that they had been in the "Caichi Pool" and there was no other. After that, everyone discussed it again and did not discuss any more valuable investigation plans.

Love to off topics has always been a characteristic of Chinese conversation, and even Qin Ge is no exception. Since the serious topic cannot be discussed, everyone started chatting. Just as everyone was talking nonsense, Sun Ting secretly called Dashou Liu aside.

"Brother Liu, are you willing to work for me?" Sun Ting was straight to the point. In fact, Sun Ting fell in love with Liu before going to the 'Caichi'. Although this person does not understand archaeology and is a little demented, he is loyal in nature and has extraordinary power and memory. He is really a rare assistant.

"What does it mean to work for you...?" Dashou Liu had never heard of the saying "Who to work for". At this time, when Sun Ting asked this, Dashou Liu was stunned.

"In this way... if you follow me in the future, I will pay you a salary... I guarantee that you will earn more than you can go up the mountain to collect herbs..." Sun Ting said.

"Pay salary..." Liu frowned, "Are you going to live here too?"

"I won't live here! Come with me!" Sun Ting was also depressed, "You are my helper and I will pay you a salary, okay?"

"Oh..." Big Hand Liu seemed to understand a little, "With you, what should I do?"

"Don't worry about this... I can arrange for her to go to the United States to treat her illness! I will arrange the residence of you mother and son!" Sun Ting seemed to be very confident about this problem. Although Liu's mother's legs and feet were not 100% paralyzed. She could walk by herself with crutches, and even cook and wash clothes. According to the diagnosis of Qin Ge and Lao Liu's head, the leg disease she suffered was not congenital or neuropathic. Judging from the superficial symptoms, it looked like the sequelae caused by the failure to treat bone trauma in time when she was young. If surgery was performed with modern medical technology, although it was unlikely that it would be completely cured, it was very likely that the old lady would throw away the crutches.

Although he didn't know where the United States was and was even less willing to leave his hometown, when he heard that he could treat his mother, Dashou Liu was still very happy and agreed without asking how much his salary was. Although Dashou Liu's mother was unwilling to leave home, she was also very excited after learning that this kind-hearted person could help him see a doctor and let him throw away the crutches that he had been using for decades. In order to express his gratitude, the old lady insisted on introducing Sun Ting to a meeting with a yellow girl in the village after learning that Sun Ting was still single, but Sun Ting collapsed and refused...

After announcing the news that he successfully "recruited" Liu Dashou, everyone was very happy. After all, following Sun Ting would have more prospects than collecting herbs in the mountains. If a "talent" like Liu Dashou can only pick medicine for a lifetime in this wilderness, it would be a pity. As for the treatment issue, Sun Ting made the decision on the spot that in addition to bearing all the costs of Big Shou Liu's mother's surgery in the United States, she also provided a house in the suburbs of Washington. Liu's salary was temporarily set at an annual salary of 100,000 US dollars. Although it was not as high as Alxun, it could be regarded as the income of the middle class in the United States.

The next afternoon, everyone arrived at the meeting place that they had agreed with the driver. Because Dashou Liu couldn't bear the sacks of herbs at home and had to carry his mother, these sacks of herbs could only be carried by Alxun and Zhang Guozhong on a shoulder pole. Although it was not very heavy, it also made the two of them tired of white-haired men sweat... (Although other things are honest and loyal, if it involves the medicinal materials he had picked, Dashou Liu is also a slander. Zhang Guozhong once wanted to give him money to tell him not to take medicinal materials, but Dashou Liu meant that he could not slander things, it was not a matter of money or not...)

After returning to Lintan County, Zhang Guozhong and Sun Ting immediately found Cui Liyan and asked if there were any signs of soaking their passport, but this time they went there with a few sacks of medicinal materials.

After thanking her for a long time, Cui Liyan recalled the incident when he discovered the passport from the deceased: At that time, the deceased was carrying a yellow crossbody bag the size of a waist bag. The outer material seemed to be a nylon, but there was indeed a layer of rubber lining inside the bag. The zipper of the bag was not an ordinary metal zipper, but a rubber zipper that had never been seen in China. The label of the bag was marked in English. All the documents, cash and some magnetic cards of the deceased were placed in this crossbody bag. According to Cui Liyan's personal analysis, the bag should be sealed in terms of material. Even if it cannot be completely sealed, it at least has a very good waterproof effect, so that the body experienced wind and rain in the mountains, while the ID and magnetic cards in the bag were as new as new, without any signs of being soaked. As for whether the crossbody bag had a complete sealing effect, because there was no experiment in this aspect at that time, Cui Liyan could not be sure.

"Does the English 'columbia' be printed on the label of the bag?" After hearing Cui Liyan's memories, Sun Ting's brows immediately frowned, "The bag is yellow, but the zipper is black?"

"I didn't pay attention to the label...but the color of the bag and the zipper is indeed yellow and black..." Cui Liyan also seemed a little surprised when he heard Sun Ting tell the details, "You have this kind of bag... Mr. Sun?"

"That is a professional outdoor waterproof bag produced by Columbia. The waterproof depth is ten meters... absolutely sealed..." It seems that Sun Ting is quite familiar with professional outdoor products.

"Is the bag sealed? That means they have not been watered, or are they still not sure?" Speaking of this, Zhang Guozhong also frowned, "Doctor Cui, are there any other paper items on them that seem to be soaked?"

"No more..." Cui Liyan shook his head, "It's certain that the time for them to have an accident was summer. The clothes were thin, there was nothing in their pockets, and no luggage was found nearby. Because the deceased was a foreign guest, the superiors attached great importance to it, so the police also conducted a large-scale visit and investigation at that time, and found that there was no registration for their check-in in the entire Lintan and even the entire Gansu hotel. In this case, I think the possibility of revenge and murder in money exists..."

"Luck!?" Although the couple didn't understand whether they had been in the 'Caichi', Cui Liyan's analysis outside the question made Zhang Guozhong suddenly realize, "Mr. Sun, I think... they may have been in the 'Caichi'! And... there is a possibility that locals commit crimes!"

"What do you say..." Sun Ting seemed to remember something when he heard Zhang Guozhong's question.

"It is impossible for them to go to the 'Caichi' two people, there must be others..." Zhang Guozhong said, "And, from the UK to China, it is impossible for them to take luggage. It is a whole day from Lintan County to the 'Caichi', so it is impossible for them to stay in a hotel! With the economic level of the Liao couple, if they stay in a hotel, they must stay in high-end hotels, at least they must stay in regular hotels. If according to what Dr. Cui said, the hotel does not have their check-in records, then there is only one possibility! They live in local people's homes!"

"Mr. Zhang, you have a very meticulous mind. It would be a pity if you don't go to criminal investigation..." After hearing what Zhang Guozhong said, even Cui Liyan nodded repeatedly, "By the way, what is the '结果' you are talking about?"

"In addition, since the cash and magnetic cards on the corpse are there, it means that the murderer is not likely to make money. According to my analysis, it may be a purpose of making a fortune! Or... silence..." Zhang Guozhong paused and did not answer Cui Liyan's question. "Whether it is a purpose of making a fortune or silence, it can only explain one problem--that is, the Liao couple went to the 'cai pond', and they may have seen something that should not be seen or something that should not be taken by them...!"

"'Qichi' is the name of a valley..." In order to avoid Cui Liyan's suspicion, Sun Ting quickly made up a lie.

"I grew up here, and I have never heard of any valley called this name..." Cui Liyan is quite fond of asking...

"Oh... this is their habit of historians..." Zhang Guozhong also began to talk nonsense, "They do archaeological things and places that they always like to name or code names. 'Qichi' is actually the code they gave to a valley..."

"Oh..." Although an amateur, Cui Liyan also knew this hobby of foreigners. The first person to discover the New World has the right to name the New World... It seems that although Zhang Guozhong was talking nonsense, this time the blind cat was considered a dead mouse...

"Chairman Zhang, according to what you analyzed... should the murderer be investigated from the local area..." On the way back to the guesthouse, Sun Ting's head was also big. He was engaged in archaeology and studied American law, but now he is a veritable private detective...

"This... I'll discuss it with everyone later... I think our work is just to prove that the murderer is or is not Dai Jinshuang. If we can prove that the murderer is a local rather than Dai Jinshuang, I don't think there is any need to investigate... That's the matter of the Public Security Bureau, and we have no right to take care of it..." To be honest, Zhang Guozhong is also very imposing. If he is placed abroad, private detectives have guns, but in China, it's illegal to hold a knife. If he really finds a prisoner, is it to arrest or not? In the event of a conflict, no matter which party is injured, the person who violates the law is himself...! If the police call the police, will the police believe what they say? How should the matter of "田游" be explained? If the government really sends an archaeological team to excavate, wouldn't it lead to a tragedy?

"Who is the naked man there?" Sun Ting was a little confused at this time. According to Zhang Guozhong's analysis, if the Liao couple's expedition team had other teammates, it would be the "naked corpse" in the 'Caichi Pool', but why did that person die in the 'Caichi Pool', while the Liao couple die outside the 'Caichi Pool'? Could it be that they abandoned their teammates? Or did the "naked brother" simply have nothing to do with the Liao couple's expedition team, and he went in at other times?

"That person... no matter whether it has anything to do with the couple or not, it is not within our investigation..." Zhang Guozhong was already in a big trouble. At this time, Sun Ting remembered the "naked man" again, which was a mess...

"But... they all have words on them..." Sun Ting seemed to attach great importance to this irrelevant clue.

"That word...it may be something that is used to get in the '生活'... As long as that kind of mechanism is triggered, there will be words on the body..." Although "mechanism" makes people think that there are words on the body, even he doesn't believe it, Zhang Guozhong is too lazy to think deeper...

With a bitter face, the two of them returned to the guesthouse, but unexpectedly, as soon as they pushed the door, they saw Lao Liu lying on the bed with his legs crossed his head and humming a small song, as if he had won a lottery.

When he saw Zhang Guozhong coming back, Old Liu laughed, "Guozhong, it's really a day in the cave, a year outside... We went to the 'Qichi' for a day, and the new clues from Young Master Liao came... I just called me..." (To be continued)
