Coming out of Xiang Yu's office, Tang Tian was about to go back to talk to Xue'er about the next plan of action, but before he could reach the door, he saw Kong Sen getting out of the car with a briefcase.

"Alas, Tang Tian, wait a minute!" Kong Sen was also stunned when he saw Tang Tian, and walked quickly to him, "I have some new discoveries, you can help me analyze and analyze!"

As soon as he heard this, Tang Tian immediately stopped and followed Kong Sen to the front of the car with great interest.

"Well, this is the Cultural Relics Bureau pulled out from the dusty archives for many years! I think it has something to do with the gunpowder in Longji Mountain!" Kong Sen leaned over and took a document from the seat of the car and handed it to Tang Tian, "According to the archives, after the hill next to the Longji Mountain Reservoir was blown up by mining back then, a tomb was exposed! The gang of illegal quarrying took secret measures to keep this news secret, and entered the tomb road without permission to explore, intending to steal the valuables in the tomb!"

"But the strange thing is that whoever enters the tomb will surely die within three days! And the death is very strange, and it is well documented that several of the dead died suddenly in the night, and they should have felt no pain when they died, because the expression of the corpse was very natural, and it maintained a calm face in a state of sleep. Judging from the autopsy report, the deceased had no obvious injuries all over his body, and his internal organs and brain tissues were also very healthy!"

"Considering this strange phenomenon, it is a natural protective layer for the tomb. Therefore, the Cultural Relics Bureau did not excavate and protect the tomb, but used mountain stones mixed with cement and steel bars to seal the tomb. ”

Tang Tian listened to Kong Sen's narration, read the documents in his hand at a glance, and finally came to the same conclusion as Kong Sen.

At the same time, Tang Tian noticed that this document stated that it was entered six years ago and sealed three years ago, but the reason for the file to be sealed was not clearly stated.

"Why was this file sealed?" Tang Tian asked with a frown.

Kong Sen smiled bitterly and waved his hand, and explained with a rather strange face: "This is a long story, in order to save costs, the gang of people who blew up the mountain and took the rocks hired a group of migrant workers to work in the mine. Most of the people who died at that time were outsiders, and the boss of the black mine suddenly fell ill and died in the detention center. The issue of compensation for deceased workers has been dragged on and has not been resolved. The family of the deceased went to Jinyang City to make a fuss, and the government came forward to negotiate with the family of the mine owner to solve the problem. ”

After hearing this, Tang Tian also understood. No matter how the media reports this, it will not be glamorous after all, and it will bring great trouble to the local investment promotion. It's reasonable to keep a low profile.

Just as Tang Tian was about to close the folder, he suddenly saw that there was a list on the last page, and more importantly, there was a name named Ma Wenyun written on this list! Tang Tian subconsciously pulled out the list and looked at it carefully.

"Oh, here's the list of the management of the black mine at the time, most of whom are still in prison. The two crimes of illegal mining and stealing tombs are superimposed, and this life is over at their age!" Kong Sen sighed with regret, those are all smart people, but it is these smart people who often commit crimes, and they are unwilling to be down-to-earth and prefer to make quick money, and in the end, the agency is too smart, but it is the second half of his life.

"The mine owner's name is Ma Wenyun, where is his ancestral hometown?" After Tang Tian finished reading the list, a bold association spontaneously emerged.

"Ancestral hometown, why are you asking this?" Kong Sen was a little puzzled, "What I mean by showing you this is to let you help me analyze and analyze, will those people who make explosives also have the idea of fighting this tomb!"

"Brother Kong, I'm afraid things are not as simple as you think!" Tang Tian took a deep breath and said with a solemn face, "This is not the place to talk, you come with me!"

Kong Sen turned his head and explained to the driver, and then walked in behind Tang Tian.

After Kong Sen sat down, Tang Tian poured him a cup of tea first, and sighed a little emotionally, "Brother, judging from the current situation, our original investigation direction is not wrong!"

Kong Sen was puzzled, but he didn't open his mouth to interrupt Tang Tian, picked up the teacup and waited for Tang Tian's next words.

"At that time, we thought that Liang Yueying's death was inseparable from Longji Mountain and the smuggling case. However, later, based on the informant's new discovery, Captain Lin investigated the case of floating corpses in the secret room and the smuggling case separately, and this is a misunderstanding!" Tang Tian said this, took out a cigarette case from his bosom and hurriedly lit one and put it in his mouth, "Brother Kong, think about it! The test results of the explosion crater in Longji Mountain show that the gunpowder is mixed with an extruder, and this kind of bulking agent is a strictly controlled substance in China! Therefore, their source can only be a sea smuggling route!"

"Well, what you said makes a lot of sense!" Kong Sen thought deeply, the two things were indeed somewhat related.

"Then, if you look back and think about it now, Liang Yueying is not only related to the smuggling case, but her death must be related to Longji Mountain! Moreover, according to my inference, the reason why she ran to Longji Mountain in the middle of the night is very likely to be to deliver extruder raw materials to the earthen workshop where explosives are made!" Tang Tian said this, casually pulled a piece of white paper and flattened it on the table, and drew three irregular circles on it with a pen, "These three circles represent Liang Yueying's death case, the Longji Mountain homemade explosives incident, and the smuggling case!"

"And then?" Kong Sen thought that what Tang Tian said was just a foreshadowing, and his eyes couldn't help but become more and more hot.

"The tombs at the bottom of Longji Mountain are these lines that connect the three circles! Because they want to enter the tomb, they need to use explosives doped with bulging agent to blow up the stone slabs used to seal the tomb back then! Because of the need for bulking agents, Liang Yueying came to Longji Mountain and came into contact with a certain secret, which was extinguished!" Tang Tian slapped the pencil in his hand on the table heavily, and said with a serious face, " Brother, you don't care about other messy things now, first go and find out where this boss Ma's ancestral home is! The root cause of Ma Wenlong's case six years ago is very likely to be here! After all, the time of death of Ma Wenlong's family is very consistent with the time when the tomb was discovered in the mine! In addition, among Wei Zhongquan and Yang Hao's other relatives, can they have anything to do with the mine boss back then!"

Kong Sen nodded, Tang Tian said this, he had already vaguely guessed what Tang Tian was going to say. If this suspicion is confirmed, it will be terrifying!

"I'm going to check the household registration relationship of the owner of the mine back then, and contact you as soon as I have news!" Kong Sen is also a fiery character, and after thinking about the stakes, he immediately got up and walked out, and he didn't even care about the matter that came to the Special Investigation Bureau to discuss with Xiang Yu. Compared with the new discovery in front of me, those clues that are quite suspicious of catching wind and shadows are simply chicken ribs!

After seeing Kong Sen leave, Tang Tian fell into deep thought. This file that I saw inadvertently completed the lack of inference that I had been unable to figure out.

If his guess is not wrong, it is very likely that Ma Wenlong and the owner of the mine are related. As for why such a complicated method was used to kill people, Tang Tian thought it might have something to do with the sick psychology of the members of the Meridian Society, or some strange ritual, right?

After thinking about it like this for a while, Tang Tian felt a wave of sleepiness hit his heart, and in order to wait for news from Kong Sen's side, he simply lay down on the desk in the office and took a nap.

When Tang Tian woke up again, it was already more than seven o'clock that night, and Xu Zhiwei knocked on his door with a smile on his face.

"What makes you smile like this?" Tang Tian asked curiously while rubbing his somewhat numb cheeks.

Xu Zhiwei put a takeaway on Tang Tian's table, and the smile on his face was even better, "Team Xiang is really powerful, he found foreign aid, it is said to be the network security team of the provincial department! In the next few days, they will be online 24 hours a day, waiting for the hacker to strike again!"

"What a fart!" Tang Tian rolled his eyes, stuffing white rice into his mouth, and said in a voice that was not very clear, "If I hadn't reminded him, would he have thought of going to the provincial hall to ask for foreign aid?"

"Huh, did you mention this?" Xu Zhiwei was stunned for a moment, and suddenly remembered Tang Tian's weird smile when he left at noon, and couldn't help but be instantly relieved, "That's right, this kind of shameless thing, you can think of it!"

"Are you talking about people?" Tang Tian couldn't wait to put the takeaway box in his hand on his face, "Can you talk well?" Kind and kind to you to find a way to break the siege, but you say I'm shameless?"

Just as the two were fighting, a police car rushed into the station of the Special Investigation Bureau at a gallop, Kong Sen jumped out of the car, and before the person reached the door of Tang Tian's office, the voice reached Tang Tian's ears, "Brother Tang, I really let you guess! The owner of the mine is called Ma Wenyun, and he is Ma Wenlong's cousin!"

Hearing this, Tang Tian hurriedly swallowed the white rice in his mouth, threw the takeaway box aside, stood up and walked towards the door.

"Brother Tang, come and see this!" Kong Sen saw Tang Tian come out, his eyes were a little more excited, and as soon as he entered Tang Tian's office, he took out a copy of the household registration information that had just been printed out from his bag.

Tang Tian took the A4 paper, and it was written very clearly that this Ma Wenyun was the child of Ma Wenlong's second uncle's family, and when he was young, his family was poor and couldn't afford to marry a daughter-in-law, so he came to Jinyang City to be a son-in-law!

"In addition to this, I also asked the police station in charge of the area, according to the recollection of the old director, who has retired. At that time, I was engaged in the household registration census, and during the census, I found that Ma Wenyun's family often had relatives from Angang City to live, and they lived there for several months!" Kong Sen paused when he said this, ran to the water dispenser and poured a cup of cold water and poured a few sips, "According to your logic, Liang Yueying was killed because she found some secret, so will Ma Wenlong's family find the same secret during the period of Ma Wenyun's permanent residence?"

"That's right! In this way, the motive for the Locked Room Floating Corpse Case is there!" Tang Tian was encouraged, his biggest headache before was that the murderer's motive for killing could not be found in the Locked Room Floating Corpse Case, but now that the motive was completed, it would be much easier to continue the investigation!

"Next, how are you going to check?" Seeing Tang Tian's eyes flickering, Kong Sen immediately guessed that he already had a plan, and couldn't help but ask.
