Because the butcher ordered me when the kiss marks on my neck disappeared and when I could go back to work in the bureau, I thought that the butcher gave me a vacation in disguise.

Early the next morning, according to the clues found by Song Chi and the account exchange certificate he handed over to me, I went directly to the bank where Nian Weiwen registered an account in the name of An Caiwen.

When I rushed there, I found that Yun Duruo arrived before me, and when I saw her, I subconsciously lifted my collar up, although I knew that it was in vain, but I don't know why I always felt these things on my neck, and I was very embarrassed in front of her.

Yun Duruo's attitude towards me was now cold again, and he didn't even look at me directly, I knew that it was useless for me to say anything now, and I couldn't figure out why I planned to explain this to a woman who had nothing to do with me.

Yun Duruo found the person in charge of the safe deposit box rental at the bank, showed his documents to explain his intentions, and asked to open the safe deposit box that Nian Weimin handled at this bank.

The staff took us to a separate room and quickly delivered a safe deposit box which was bigger than I expected, the staff told us it was the largest safe in the bank and opened it in front of us.

Yun Duruo and I were shocked at the same time the moment the box was opened.

I thought about it for a long time last night, and I was always curious about what Nian Weimin would put in the bank safe the day after Mu Hanzhi's death, and it would be twenty years after Mu Hanzhi's death, and he still deliberately used An Caiwen's name, which was enough to see that the contents of the safe must be very important to him.

The safe is just an ordinary vase with cracks, look at the shape of the vase is a copper amphora porcelain vase, there is a circle of carved copper wrapping in the bottle body, the ears are cast with pure copper, not a precious thing, just a decorative utensil, but there is a deep crack in the bottle body, it can be seen that the vase has been hit.

But Yun Duruo and I understood at first glance that this vase should be a pair, the one in the safe, and the other is now on the wardrobe in Mu Hanzhi's bedroom.

From the photos given to us by Zhou Baiman, as well as the photos of the on-site exploration on the night of Mu Hanzhi's death twenty years ago, it was found that this vase was lost that night, but I didn't expect it to be hidden here by Nian Weimin.

Through the traces of blood splashing in Mu Hanzhi's room, it has been known that Mu Hanzhi may have been attacked by a heavy object and died, but the murder weapon has not been determined, looking at the vase in front of him, Yun Duruo and I both understood something.

Yun Duruo drove the vase back to the bureau, because of the butcher's ban, I had to sit in the car honestly and wait for the appraisal results, until it was almost time to get off work in the afternoon, Ling Guodong hurriedly walked out of the bureau with Yun Duruo.

"Why don't you go in......" Ling Guodong only said half of what he said as soon as he got into the car, and looked at my neck with his mouth wide open.

"What are the results?" I know what Ling Guodong is going to say next, which pot is not opened, not to mention that Yun Duruo is still beside him, it is impossible for everyone to slap me in the face in front of her once to be satisfied, I diverted the topic and asked directly.

On the vase we found in the bank safe, Ling Guodong verified that the blood stains on the vase matched Mu Hanzhi's identity, and the human brain gray matter and cerebrospinal fluid were also found on the pure copper ears on the vase, which were also consistent with those found in Mu Hanzhi's room, and after comparing Mu Hanzhi's autopsy report twenty years ago, it was confirmed that it was Mu Hanzhi himself.

Ling Guodong's test results confirmed Yun Duruo's and I conjectures that Mu Hanzhi was killed in his room that year, and this vase was the murder weapon that killed Mu Hanzhi.

"There's another big discovery." Ling Guodong said with some excitement.

"What discovery?" I asked.

"Fingerprints were taken from the vase." Ling Guodong replied.

Since the case of the nameless female corpse, there have been a series of murders that have occurred, and no useful fingerprints have been extracted, but I didn't expect to be extracted on the vase, and I just smiled excitedly, and immediately gloomed again.

"Nian Weimin's?" I asked tentatively, in my heart, Nian Weimin and Mu Hanzhi's death have been directly linked, and now that the murder weapon has been found, my first reaction is that Nian Weimin may be the murderer of Mu Hanzhi, and it is not surprising to find his fingerprints on it.

"It's not!" Yun Duruo could see that he hadn't lost his temper yet, but he was quite professional in business, and said seriously. "What was extracted was a woman's fingerprint."

"We restored the fingerprints on the vase, only the woman's, but not Mu Hanzhi's." Ling Guodong said.

I immediately thought that among the four pairs of footprints found in Mu Hanzhi's room, one of them was a woman's, and my conjecture was quickly confirmed by Ling Guodong, the fingerprints found on the vase were restored to the posture of the woman holding the vase, and this posture could cause fatal injuries with the pure copper ears of the vase if it was just enough force.

"Yes...... It was that woman who killed Mu Hanzhi with a vase! I muttered to myself in some shock.

Ling Guodong nodded and said to us, the remaining blood stains on the vase overlapped, and it can be seen that the blood splashed on it more than once, indicating that after the woman attacked Mu Hanzhi with the vase, she smashed it on the back of Mu Hanzhi's head more than once, which could make Mu Hanzhi's brain burst, if it weren't for the body of the vase being wrapped in a hollow carved copper edge, the vase would have been shattered long ago.

From the current test results, it has gradually become clear what happened in Mu Hanzhi's room twenty years ago, Mu Hanzhi was killed by this woman with a vase, this woman is the main culprit, and the others except for Nian Weimin, who has died and was confirmed to be present, he and the other two people all assisted and indirectly participated in this murder.

"I've handled a lot of homicide cases, and the first reaction to a murder should be to erase the traces and dispose of the murder weapon to cover up the crime." Yun Duruo said to us in some surprise. "But why did Nian Weimin hide this murder weapon in the safe? Even if he didn't kill directly, he was also an accomplice, I remember An Caiwen said that the first thing he did when he went home after the crime was to dispose of the bloody clothes, so why did he save this murder weapon stained with Mu Hanzhi's blood? ”

I took out a cigarette and handed it to Ling Guodong, took out one and put it on the corner of my mouth, what was the bloody case in Mu Hanzhi's room twenty years ago, it is still unknown, but Nian Weimin has confirmed that he is only an accomplice at best, although he is extremely vicious for the tiger, but a businessman who can mix from a warehouse keeper to a rich party is enough to see that Nian Weimin's IQ is not low, and he is not stupid enough to leave a murder weapon.

And by using An Caiwen's name to register an account and go to the bank to apply for a safe deposit box, it can be seen that this murder weapon has other meanings and uses in Nian Weimin's heart.

"Nian Weimin made his fortune after Mu Hanzhi's death, but no one knows how he made his fortune." I took a puff of my cigarette and said thoughtfully. "And there is another point, the main reason for Nian Weimin's career is that he undertakes the supply of building materials for a large number of urban construction projects......"

"I have repeatedly studied Nian Weimin's files, and his network of interpersonal relationships was very simple before Mu Han died, and there seems to be no one who can help him become the largest supplier of urban construction materials." Yun Duruo said.

"That's not right, Nian Weimin asked for money before he made his fortune, it doesn't matter if he wants it, it doesn't matter if he wants it, he is kept in an obscure warehouse, and it stands to reason that he can't get in touch with urban construction projects at all, let alone contract construction and supply materials." Ling Guodong also said puzzled.

"......," I said after a long and silent thought. Coerce! The only reasonable explanation for leaving the murder weapon vase is that Nian Wei used it to blackmail him! ”

"Threaten ......" Yun Duruo lowered his head and thought about it after hearing this, and slowly nodded. There is this possibility, Nian Weimin knows that as long as the murder weapon is in his hands, the murderer will definitely obey him, so he will keep the murder weapon so carefully. ”

"From the side, it also reflects that this murderer is not an ordinary person, and he can let someone like Nian Weimin undertake the supply of building materials for urban construction projects, which shows that this person's relationship and background are not simple." Ling Guodong said.

"This is a new clue, as long as you follow Nian Weimin's relationship network and find out the person who provided the project to Nian Weimin in the first place, it is very likely that the murderer will be found." I said excitedly.

Sure enough, it was Skynet that was restored and not leaked, and the vase left by Nian Weimin became a flaw in the murder case twenty years ago, Yun Duruo hurriedly got out of the car after hearing this, and she said that she would immediately arrange for someone to start investigating Nian Weimin's interpersonal relationships and frequent contacts.

Ling Guodong's eyes were still on my neck when he got out of the car, it seemed that his curiosity was not small, just about to ask, I opened the car door and left, I didn't turn my head back to wave my hand at him behind me, only dropped a sentence, it was hard to say!

I was sitting on the corner of the street, and the butcher prevented me from going back to the bureau, and I suddenly realized that there were not many places I could go, and now I really couldn't find a place to go except to go back to Han Yu's Lethe inn.

When the cigarette at the corner of my mouth was almost finished, I just got up and saw the prince standing in front of me, he has always given me the impression of being very indifferent, there is a taste of heart like stopping water, I don't know if it is pretended, anyway, I don't have much affection for people with tattoos on their bodies.

I didn't expect to meet him here, I have nothing to say to him logically, I took a deep puff of smoke and glanced at him, and found that his eyes today were obviously a little different from before, he methodically played with the string of Buddhist beads in his hand, I actually saw a trace of surprise and confusion in his eyes-

I suddenly realized something around my neck and pulled at my collar uncomfortably.

"Be careful tonight!" The prince said calmly, but in a serious tone.

I was stunned, the fire rushed up, and a gangster dared to threaten the police in broad daylight, and just wanted to ask him what he meant, Yun Duruo's car stopped in front of us.

"Get in the car."

I didn't say this to me, I watched angrily as the prince got into Yun Duruo's car, she was frosty in the car, and she didn't even look at me, it was obvious that the prince was waiting for her here.

Before the prince got into the car, he looked back at me again, and fell into my eyes, remembering what he had just said, if I hadn't been able to beat him, I would have rushed up.
