In the early stage, because of the lack of manpower, Zhang Xingcheng assigned the task to their respective yamen, the military department to investigate the tomb guards, and the Ministry of Industry to investigate the craftsmen.

The way of investigation is very simple, there is no technical difficulty, that is, to check the person, to see who has left alone and how long.

As for those soldiers guarding the tomb who were not in the Yuanling, they sent someone to find them.

The rules and regulations of the mausoleum guards are very strict, and it is a little unkind to not allow leave or anything, but where the leave went and what was done must be explained in advance.

That night, in the camp of Yuanling, Zhang Xingcheng and several people finally met.

Although several people were near Yuanling during the day, they were also busy with their own things.

Today, the old man personally went down to take a look, and the inside was indeed emptied, and he ordered people to search around several times, and found traces of carriages carrying heavy objects. The old man has ordered someone to follow the traces to find him, but there is little hope. Zhang Xingcheng briefly said about his achievements today, "Now only two points have been determined, the first point is that the location they chose is very tricky, at night, the patrol tomb guards are not close, and it is not easy to find at all." The second point is that the funerary goods were transported by horse-drawn carriage, and it was a two-wheeled old-fashioned carriage. ”

"If you want to find the target through this clue, it's difficult!" Zhang Liang shook his head.

Stealing is actually no different from military combat, both must be careful, and no one can find out their whereabouts when sneaking up.

And there is training in the army to cover up their whereabouts, and there are all kinds of ways, if the other party also understands this set, unless someone sees them, it is basically impossible to find clues through traces.

As long as people walk down the road, you can't find anyone even if you cut off your head.

"The Tomb Guards didn't find any problems here, since the beginning of the year, the people who asked for leave are basically one day's time, and they leave the camp at sunrise and return at sunset, but one person has been away from the camp for a few days, but the reason for reporting is that the mother is seriously ill, and the old man has sent someone to investigate, if it is true, the Tomb Guarding Army is at least no problem on the surface." Zhang Liang continued.

"There is no problem with the craftsman's side, the family is all here, and no one has left the mausoleum area."

"There will always be clues, tomb robbery will definitely not be a matter of a while, just digging that passage, it is difficult to do it in half a day, let alone when the lights are blind at night? And with such precision in the selection of seats? The old man was a little suspicious, it should be an acquaintance who committed the crime. Zhang Xingcheng said his doubts.

"Acquaintances?"

"Yes, acquaintances, craftsmen who built the tombs, people who entered the graves, these people are suspicious......"

The discussion lasted all night, and all kinds of speculations and reveries emerged one after another, and Zhang Xingcheng asked people to record all kinds of ideas and possibilities, and they would be verified after dawn.

After all, Zhang Liang and the others still have their own work, although finding out this matter is the first task, but they can't completely abandon the things in their hands.

Especially in the days when the war on the border is imminent, the military department is busy.

It is necessary not only to step up urging all localities to reorganize their armaments for war, plan the transfer of materials, calculate the time and so on, and so on.

On the second day, Zhang Liang and others stayed here for a whole day, but unfortunately they didn't find anything, so they could only temporarily return to Chang'an, leaving Zhang Xingcheng and others to continue the investigation.

Of course, although Zhang Liang and the others are gone, there are still a few people left here to help in the deployment or something, and the capable people drawn from all over the country are gradually coming.

Half a month later, with the cooperation of dozens of case-handling experts, the clues were completely broken.

The sergeant who took a long leave of absence was indeed at home, his mother had also died of illness, and was preparing for the future, and many people proved that he had not left since returning home, for this reason, he also specially found a servant to examine his mother's body, although some were not very respectful, but the matter was very important, the result was that there was no external injury, no poisoning, because the person was dead, there was no pulse, so the cause could only be roughly guessed according to its form, and the final result was a normal death.

On the other side, Zhang Liang's worries were not useless, the carriage did go on the road, but after it got on the road, there was no trace, and it could only be judged according to the traces of less than one step, the other party's purpose was to the east.

A large number of visits and investigations, door-to-door inquiries, but what happened at night, no one would know at all, and even if someone heard the movement, they would not go out to check.

Therefore, after half a month of investigation, it is still impossible to determine when the other party committed the crime.

In desperation, Zhang Xingcheng could only give orders to the state capitals through Zhongshu Province to pay close attention to the people from around the New Year to the present, and suddenly made a generous move, hoping to find some clues in this way.

But it is tantamount to looking for a needle in a haystack, and it is even more difficult.

Half a month of rigorous investigation, no matter how concealed it is, it is impossible to hide it from everyone's eyes.

There was no such gold in Chang'an again, and those people seemed to have evaporated from the world, and there was no news.

Gradually, Chang'an City began to be shrouded in a haze atmosphere.

Some people say that some people want to rebel, otherwise why did the inventory in and out of the city suddenly become stricter? Even ordinary people don't let go?

Some people say that they are catching assassins, and some people say that someone is not long-sighted and beats the son of a certain big man's family.

There are different opinions, but no matter what, the atmosphere in the entire Chang'an City has become extremely depressing.

"How's the investigation going?" In the Tai Chi Palace, Li Yuanji, who was in a very unhappy mood, asked again.

In the past half a month, Chang'an has almost been in a state of semi-martial law, and the yamen have also been in a state of semi-shutdown, which has not only left some haze for the people, but also has constant complaints from the DPRK and China.

"I have no clue, the other party seems to know that the imperial court is investigating them, so during this time, neither the money bank nor the shop has received this kind of gold, and even the states and counties have not found a large number of gold-related things when they check the goods. The minister investigated the Yuanling Tomb guards and construction craftsmen, investigated the construction craftsmen of the Cai Guo Gong Curtain and the people who entered the Cai Guo Cemetery during the period, and there was basically alibi evidence if there was a suspicion, either they entered the city and had a record in the city, or they visited relatives and some people testified.

Now almost all the clues are broken, unless the other party reappears, otherwise, you can only go through the existing clues to see if there are any missed places. Zhang Xingcheng reported with a haggard face.

All the methods that can be used have been used, and those who have a little hope have all sent a large number of personnel to investigate, and countless manpower and material resources have been mobilized in half a month, and now there are more than 100 case-handling personnel transferred from various places alone.

All kinds of methods, all kinds of possibilities, the scene has been seen dozens of times, and even the tomb has been visited no less than ten times, but no useful clues can be found.

It's not that the ancient case-handling personnel were incompetent, but in ancient times, it was really difficult to handle a case.

There are no monitoring facilities, no fingerprint comparison, no DNA testing, nothing, everything can only be solved by experience, human evidence, and physical evidence.

"Chen is now afraid that it is a person with military experience who will commit the crime......" Although he was very reluctant, Zhang Xingcheng still had to express his worries.

In such a case-handling environment, if the other party is from a military background, then the possibility of being caught is very small.

A person who understands counter-reconnaissance, let alone in the era of harsh conditions in ancient times, even in modern times, when all kinds of eyes are flying in the sky, it is difficult to catch traces.

Why do local governments contact their troops and ask them to send someone to solve a crime?

Is it really a place that doesn't work? Not necessarily, but because his troops trained him and knew him best, they could often find a flaw and catch him.

"Wharf, have you checked the coal seller?" Li Yuanji also asked a little impatiently, "There is so much gold, I haven't seen it in Tongguan, if they don't leave, they must still be in Guanzhong now, and melting gold requires a lot of coal, maybe you can start from this aspect." ”

Iron-making, alchemy, and all coke are used, but the management of coke is extremely strict, and it is not sold to the outside world, and the data of coke purchased by each workshop must also be strictly reviewed.

It is definitely not possible to burn it with firewood, so you can only use coal, a large amount of coal.

"I checked on the dock, and there was no suspicious phenomenon, but the coal side didn't think about it yet, so the minister will arrange it." Zhang Xingcheng was stunned and secretly scolded himself for ignoring this.

Of course, the main reason is that I don't know this knowledge, so I ignore that melting gold is burned with coal, and a lot of it has to be burned.

"Your Majesty......" Ma Wu hurriedly entered the main hall, glanced at Zhang Xingcheng, and did not shy away from it, and said directly: "There are traders in the city who reported that our people caught a merchant from the Western Regions, and he found ten taels of gold on him, plus five taels spent, a total of fifteen taels. ”

"Merchant of the Western Regions?" Li Yuanji frowned, this thing was done by people from the Western Regions? Do they have the guts?

"The man from the Western Regions said that someone bought his goods outside the city, and the fifteen taels of gold were the money for him, and he had some more, a total of fifty taels." Ma Wu continued.

"Sure enough, he is a smart person, not only aware that the imperial court is investigating this matter, but also thought of other ways to cash it out, but unfortunately, some of them are too smart!" After saying that, a fine light flashed in Li Yuanji's eyes.

If the other party disappears without a trace with the money, or runs to the Western Regions to find a way to cash out, there is no way.

It's a pity that the other party is too arrogant, and since he sensed that the imperial court was investigating this matter, he dared to spend this money near Chang'an.

Even if you change money, you still buy goods? I really don't know how to write dead words.

"Check! Check his goods, check them one by one in the surroundings, with goods always have to be sold, even if they are not sold, they will be seen where they are pulled, I still don't believe in the power of Datang, I can't catch a single mouse! ”
