Wan'er set it up in the computer, and after a while, she looked up and said, "Okay, I've already emitted interference waves in the car, even if someone wants to eavesdrop, it's impossible." Boss, if there's anything you can say now. ”

Song Qian nodded and said: "Since you all already know the role of Yin soil, then I will tell you one more situation, the collection of Yin soil is very difficult, once it leaves the formed environment, it will not take long for it to volatilize in the air, so the collection of Yin soil in the legend requires special means, and those who can use this means can only be done by masters in a few places in China." ”

Shangguan Yu and the others were very interested when they heard this, and said, "Then how do you know?" ”

A hint of nostalgia flashed in Song Qian's eyes, his knowledge in this area basically comes from his father, and some of it comes from "The Collected Records of the Criminal King", although it chats about tens of thousands of words, but the content is all-encompassing, when Song Qian didn't understand the content when he was a child, when he encountered actual problems, similar impressions often appeared in his mind.

"Could this be the real secret of the Records of the Criminal King?" Song Qian even wondered if it was related to his own bloodline of the Torture King, but this matter was too mysterious, so he didn't study it in depth.

Song Qian glanced at everyone and said in a deep voice, "This is my secret. ”

"Oh, since it's a secret, forget it." When Shangguan Yu and the others heard this, they took the initiative to give up their plans to learn about it.

Song Qian shook his head and said: "Although it is a secret, I decided to share this secret with you, we are a team, the more everyone knows about me, the more tacit cooperation will be in the future battles."

So Song Qian told his father about the way he had educated himself since he was a child, except for the matter of the collection of the criminal king, everything else was basically clear.

"I see, no wonder you were so talented at tracking enemies last time, it should be the result of your uncle's training since childhood, right?" Shangguan Yu suddenly realized.

"Alright, it's time to get down to business, boss, what is the destination of our mission this time?"

Wan'er and Shangguan Yu were also very curious, why did Song Qian rush to the south so urgently?

"South... Jiang..."Song Qian said two words mysteriously.

"Southern Xinjiang? What is that place? Ah Jian and Shangguan Yu didn't understand at all, while Wan'er looked at him with a thoughtful look on her face and said, "Boss, did you guess anything from those two words?" ”

Song Qian nodded and said, "That's right, you can look at the words at the light." ”

After that, Song Qian asked Ah Jian to take out the rice paper from Yu Gao Ge's study, there were two words on it, and they were only half written.

Ah Jian turned on the lights in the car, looked at the lights, and said in surprise after a while: "Hey, there are words under this cross!" ”

His words attracted both Wan'er and Shangguan Yu, and the two of them also took it over and looked at it for a while, and they both saw a hint of clues, and said: "It is indeed a word, it looks like an ancient word, and it seems to be an auspicious word." ”

Song Qian interrupted their speculation and said, "It's the Nanzi, and the word that hasn't been written yet, it should be the Miao character, and it is Nanmiao when connected!" ”

"Nan Miao? Hmong? ”

"No wonder you let us go to Southern Xinjiang, I see!"

The three of them suddenly realized, but then Shangguan Yu snorted unconvinced, and said, "Why is your guess necessarily right, but our guess is not?" ”

Song Qian smiled slightly and said: "In a case, many things cannot be viewed in isolation, but should play the role of our brain's association. ”

"If there is no Yin Earth Incident, I think it is possible whether it is Gu or Ji, after all, the ink has been soaked for too long, and the original handwriting has been covered, if it is not for the killing of the eldest brother, I am afraid that we will not be able to restore the original words he wrote from the handwriting."

This technique was also learned by Song Qian from the "Collection of the Punishment King", which was basically written with a brush in ancient times, and once it was dyed with ink, the original handwriting would be covered up.

However, the ancient criminal investigators thought of a wonderful way, which was to look at the rice paper in front of the light, and through the light, the original handwriting could be vaguely seen.

Yin soil comes from cold and damp places, and the people who can take and preserve this substance only exist in the southern part of the country, that is, the Miao people in southern Xinjiang who are still in a state of ignorance and uncivilized.

The matter was explained clearly, and then everyone was more curious about the arrangements behind, Wan'er said: "Southern Xinjiang is so big, although the number of Nanmiao is not much, but it is also relative to the national population, we look for it like this, it is tantamount to looking for a needle in a haystack!" ”

Song Qian said: "There are two important clues, one is a sentence that Brother Shangguan whispered when he left, he said that before killing Big Brother disappeared, he was investigating a mysterious case of missing persons. ”

"This case was investigated privately by the eldest brother, and no one in the entire police station knew about it, if it weren't for the fact that one of Shangguan's eldest brother's downlines inadvertently revealed a hint of tone, even Shangguan might have been kept in the dark."

Shangguan Yu glanced at Song Qian strangely and said, "Why didn't my brother tell me the news, but told you?" ”

Song Qian shrugged and said, "Maybe it's a problem of character." ”

Shangguan Yuqiao's face tensed, her eyebrows raised, and said, "Song Qian, you don't want to live anymore?" ”

"Well, I mean, Brother Shangguan probably thinks I'm honest and reliable, so he told me."

"Then you mean I'm dishonest and unreliable?" Shangguan Yu's eyes showed a dangerous look, and after the family's problems were resolved, her nature returned to her previous state.

Song Qian's eyes flashed with a hint of relief, in fact, he deliberately made Shangguan Yu happy, seeing her performance, a big stone in his heart finally landed.

Wan'er asked without a trace: "Then there is another clue?" ”

Song Qian said: "Another clue has to be discovered by Ah Jian, the yin soil generally only appears in the ancient tombs, as long as you get there, I think as long as you investigate from these two clues, you will definitely have a harvest." ”

It took more than ten hours, Song Qian and a few people drove from Haicheng to Ningcheng, the southernmost city in Gui Province, in order not to alarm other people, a few people did not go far from the Yanjiang Expressway, they got off the highway in a place without an electronic eye, and then walked onto the national highway and disappeared from everyone's sight.

Coupled with Wan'er's electronic signal shielding, it can be said that no one knows where Song Qian and the four of them are now, unless it is to track their mobile phone signals.

The overnight group had already given the four of them a specially processed mobile phone, and in addition to the equipment of the night group, the others could not be found by detectives.

These preparations were already thought of by Song Qian, in order to deal with the Zhao family, the Tian family and the Huangfu family.
