Xiao Lianshan's affirmation is undoubted, he won't lie and I'm pretty sure he's telling the truth now, I licked the corners of my mouth and asked what happened next, Xiao Lianshan put down the teacup in his hand and told us calmly.

He didn't know what the purpose of the Japanese was to kill these people, let alone who they were killed, Xiao Lianshan went to the mausoleum to track Liu Weiming and planned to find the whereabouts of Yang Kou, but after he entered the mausoleum, he found that Liu Weiming and others had been killed.

Xiao Lianshan cleaned up the footprints left in the mausoleum in order not to make extraneous branches, and accidentally left the pen holder in the mausoleum when he left.

"You've been to the mausoleum...... Left the pen holder! Yun Duruo was stunned and suddenly turned her head to look at me, she should know why I hurriedly returned that day under the pretext of being unwell.

Even Han Yu was dumbfounded, he probably didn't expect me to bend the law to clean up the scene and hide clues for personal gain.

"You don't have to look at him, yes, he found the pen holder in the mausoleum and brought it back to me." Xiao Lianshan said righteously. "I have been to sit upright all my life, I can't say anything to people, I have been to the mausoleum, but Liu Weiming and the deaths of others have nothing to do with me, I clean up the footprints just because I don't want to cause trouble."

"I'm sorry, I should have told you beforehand, but all the focus was on my dad at the time, and I didn't want you to have a preconceived idea until I asked." I said apologetically to Yun Duruo and Han Yu.

"Forget it, you are also for your father, in fact, we have been able to confirm that it should be Fusang who killed Liu Weiming." Yun Duruo pursed his lips and smiled faintly.

I avoided Yun Duruo's gaze, because Xiao Lianshan only said half of what he said, and he hadn't explained to me clearly until now who the bloody clothes I found in the bathroom, and the bloodstained blood on the clothes that Gu Anqi didn't have time to change.

Xiao Lianshan continued, as for why he went to see Ge Xiaobai, the reason is the same as ours, because Ge Xiaobai is an archaeological expert in this area, Xiao Lianshan just wanted to ask Ge Xiaobai to see the content of the letter, and wanted to see if he could get more clues from Ge Xiaobai.

"I know that the Fuso people are killing people for the sake of Genghis Khan's mausoleum, and I want to stop it, but the problem is, I don't know where these people they are trying to kill are." Xiao Lianshan said to us with a gloomy expression. "The Fuso people know and grasp the Mausoleum of Genghis Khan far more than we do, and it is conceivable that they can know the lock dragon buckle."

I thought I could learn the truth here in Xiao Lianshan, but in the end I found out that he didn't know much like us, and the Fusang people found Xiao Lianshan just for the letter, but it can also be seen that there must be something important in this letter related to Genghis Khan's mausoleum.

There are still ten days left, we left Xiao Lianshan and rushed back to the bureau non-stop, the situation of the investigation in Liang Xiaocheng was not helpful to the case, and when I returned to the office, Yun Duruo looked very tired, sitting on the chair weakly, and I was a little worried when I looked at her.

"Since your dad doesn't know, how can we find the next victim?" Han Yu said in a deep voice.

I poured a glass of water for Yun Duruo, she smiled at me weakly, I was so worried that something would happen to her, but it was still fine when I went to Zenqing Temple, how could it become like this as soon as I came back, no matter how I asked, the explanation I got was not to worry, she just didn't rest well.

"Judging from the current situation, the common denominator of the people killed by the Fuso people is only people with tattoos on their chests, but these people have no intersection no matter how you look at them." Yun Du said thoughtfully. "There are still ten days to go, and to find these people, you have to find the same places between them."

"One more thing is the same!"

The voice came from behind us, Nangong Yifeng came in, she has been investigating the information of the five people who were killed before this time, and I haven't seen her for a long time.

"Are your eyes better?" Nangong Yi looked at me excitedly.

"No, but it's under control for the time being." I rubbed my eyes and replied with a smile.

"Don't talk about the past, when is it?" Han Yu interjected and looked at Nangong Yi and said seriously. "We calculated the time and method of killing people of Fuso, and the people of Fuso would choose a cloudy day every month to commit murder, and the method was in accordance with the criminal law of the eighteen layers of hell."

"No wonder, Xie Tong died in the steamer, and Liu Weiming was cut by a thousand knives......" Nangong Yi nodded after hearing this. In this way, it seems that the Fuso people's murder was planned in advance. ”

"What is still unclear is the purpose of the Fusang people's killing, perhaps for the purpose of killing people at Genghis Khan's Mausoleum, and from the current point of view, the people who don't kill are related to Genghis Khan's Mausoleum." I said with a deep breath.

"It's strange that the Fusang people have asked Rong Yan's father to cooperate and open the tomb of Genghis Khan together, on the condition that the wealth inside is not taken, as long as there is one thing in the mausoleum." Yun Duruo said in surprise next to him.

"This is also what I don't understand, Genghis Khan's Mausoleum can be said to be the biggest treasure so far, how many people have spent their lives trying to find it is nothing more than for the mountains of wealth inside, and the Fusang people have been exploring for more than a hundred years and it is not for these." I said with a frown. "What could be more important in the mausoleum than the wealth of the world?"

Nangong Yi lowered her head and pondered for a long time, and said with a solemn expression.

"In this way, there are only ten days before the next murder of the Fuso people."

"Yes." Han Yu nodded and looked at Nangong Yi and asked suspiciously. "The most important thing now is to find out the pattern of the Fuso people's killing, that is, the connection and commonality between these killings, except for knowing that they all have tattoos on their chests, there seems to be no connection between the others."

"Didn't you just say that these people have one thing in common?" I looked at Nangong Yi and asked.

Nangong Yi nodded and told us that Xie Tong is cook is only thirty-seven years old, and the lock dragon buckle is the most important thing to open Genghis Khan's mausoleum, it stands to reason that this lock dragon buckle will not appear in Xie Tong's hands, so Nangong Yi began to investigate Xie Tong's background.

Liang Xiaocheng said that Xie Tong's ancestors have been living in Yongning Village, and according to Zhong Yulin's confession, Xie Tong said that the treasure in the family was handed down from his ancestors after he was drunk, which shows that the lock dragon buckle has always been inherited by Xie Tong's family, that is, Xie Tong's ancestors should be related to Genghis Khan's mausoleum, so Nangong Yi followed this line to investigate.

"Xie Tongzu's last three generations were surnamed Xie, but when I checked further, I found that their family was not actually surnamed Xie." Nangong Yi said to us excitedly.

"That'...... What's that last name? I asked, surprised.

"Chaganbala." Nangong Yi said calmly. "This is the name of the Mongols, and in Chinese Chaganbala means white tiger."

"Mongolian ......," Yun Duruo's eyes lit up, and he stood up from his chair. Xie Tong is a Mongol. ”

"Yes, not only thank you, but after I learned of this result, I searched the files of the other four deceased to trace their backgrounds." Nangong Yi nodded and said in the affirmative. "It turned out that the five people killed were all Mongols."

I nodded thoughtfully, took out a cigarette and put it in the corner of my mouth, it seems that these people are indeed related to the tomb of Genghis Khan, at least their ancestors should know about the secret that has been hidden for hundreds of years.

"And Xie Tong's ancestors are not small, they are the head of thousands of households in Genghis Khan's guards, equivalent to the commander of the Imperial Forest Army, and he has made great achievements in accompanying Genghis Khan's expedition to the east and west, and he is regarded as a confidant general because he has repeatedly saved Genghis Khan." Nangong Yi looked at us calmly and said.

I lit a cigarette and took a deep breath and walked back and forth in the room for a few steps, Xie Tong's ancestors should have a very high status if they were fierce and loyal, but Genghis Khan's Mausoleum is such a huge imperial mausoleum, and there are countless riches piled up in it, why is such a big treasure key in the hands of Xie Tong's ancestors.

The lock dragon buckle was passed down from generation to generation until it appeared in Xie Tong's hands, but it can be seen that Xie Tong only knew that the lock dragon buckle was very important, but he did not know the relationship between the lock dragon buckle and Genghis Khan's mausoleum, and there was another place that I couldn't figure out, since Xie Tong's ancestors were Mongolians, why did Xie Tong live in Yongning Village.

Regardless of Xie Tong, none of the five people killed before lived in Mongolia, of course, this may be due to the passage of time, their ancestors have all migrated out of Mongolia, but this is too much of a coincidence.

"Xie Tong's ancestor is famous, so have you checked the origin and background of the ancestors of the other four deceased?" I looked at Nangong Yi and asked.

"No, it's been too long and the other people's places are scattered, and they should have migrated from Mongolia to various places, because the tracing is incomplete when there is no genealogical survey." Nangong Yi shook her head and replied.

"Since the Fusang people are killing people according to the criminal law of the Eighteen Hells, it means that there are eighteen people to be killed, and these eighteen people are likely to be Mongols like the previous five, and their ancestors should have followed Genghis Khan, so they knew the secret of Genghis Khan's mausoleum." Yun Duruo pursed his lips and said anxiously. "Even if we know that the ancestors of these people are Mongols, how can we find them on the basis of this alone?"

Han Yu didn't speak for a long time, his fingers kept writing and drawing something on the table, and suddenly said meaningfully.

"Do you remember what Qiu Chuji said when he was confused?"

"Timber wolves chase deer and blood." I nodded and looked at Han Yu in surprise. "This should be Qiu Chuji revealing the secret of Genghis Khan's Mausoleum to his disciples, but no one has been able to decipher the meaning so far."

Tianjiao is mentioned in these words, and the word Tianjiao comes from the "Book of Han. The Legend of the Huns" Tianzhizi also refers to the character of Xiong I, and the Tianjiao in Qiu Chuji's words should refer to the heroic and strategic characters in the foreign race, and Tianjiao should refer to Genghis Khan. Nangong Yi sat down and thought about it and said.

"What does it mean for a timber wolf to chase a deer?" Yun Duruo also sat down slowly, and among the few of us, Nangong Yi was the most knowledgeable.

"If taken literally, these two sentences are not difficult." Nangong Yi watched us and spoke slowly.

In the first sentence of the opening chapter of the Secret History of Mongolia, it is written that Genghis Khan's ancestor was born by the Mandate of Heaven, and his wife Huoemararan crossed the Tengji Sihai Sea to live in front of the Buerhan Mountain, the source of the Troubled River, and gave birth to a son named Bata Chihan.

"Scholars of Mongolian history point out that this is a totemic myth that has been passed down for a long time, and that we are called the descendants of the dragon, and in Mongolian it means pale wolf, and in Mongolian it means white deer." Nangong Yi said to us unhurriedly.
