Jian Jing finally agreed to the landlord's request. However, it was not because she was afraid of him, nor was she moved by his love for his son, but because the system issued a task.

[New task has been issued]

[Task name: The Secret of the Wedding]

[Description: In the season of cherry blossoms, the white wedding banquet, the beautiful days are stained with blood? Why did the bad news of death come, and who is the sad song? Please find out the truth]

[Task rewards and penalties: Success rewards 30 courage points, failure no punishment]

The world is big, and the card draw is the biggest.

Jian Jing asked for an autopsy first.

The landlord looked around and called the name of Lu, the best man: "Xiao Yu, you have to suffer a little today and accompany Miss Jian to look around, so as to help cover up."

Lu, the best man, glanced at her and nodded: "Okay, leave it to me."

The landlord showed satisfaction. See, this is the feedback he wanted. A girl like Jian Jing, who is young and hot-tempered and not sensible enough, would never be used by him in normal times.

But there is no way, she is Jin Wu's person, he can't think of ways to shut her up, so he can only make her play the biggest role. If she is really as smart as Lu Yu said, it would be a pleasant surprise. ——No matter how the superiors judged from a high position, Jian Jing

didn't care about it.

As soon as she entered the scene, she switched to reasoning mode.

With her hair tied up, she took out shoe covers and gloves from her bag and put them on, and then put on a disposable mask. Then she walked cautiously to the body to check.

The deceased was the groom.

He was lying on the sofa, one hand hanging down, the other on his abdomen, his head tilted to one side, as if he was sleeping soundly. But the presence of rigor mortis and body spots indicated that he had died about 1-3 hours ago.

Moreover, the body spots this time were very special. They were not the usual color, but bluish-brown.

Jian Jing checked his fingernails and oral mucosa and found that they were also bluish-purple.

"Is this poisoning?" asked best man Lu.

She nodded: "Very typical symptoms of nitrite poisoning."

In a normal human body, divalent iron combines with oxygen to form oxygenated hemoglobin. Oxygen is loosely bound to hemoglobin and is easily transferred and released in blood vessels. However, the nitrite ions in nitrite oxidize the divalent iron in hemoglobin to trivalent iron, forming ferrous hemoglobin, which cannot carry oxygen, affecting the release of oxygen, leading to hypoxia and suffocation. (Note 1)

Because of the lack of oxygen, the blood appears dark brown, and through the skin, the body spots become bluish-brown purple, which is very easy to identify.

"But this is a preliminary judgment, and the details require an autopsy." Jian Jing said, "If you don't call the police, how about an autopsy?"

Lu's best man flatly refused: "Not for the time being."

"You can't do an autopsy just by looking at it with your eyes. The cause of death is not clear, don't even think about solving the case." Jian Jing rolled her eyes.

Best Man Lu asked, "Don't you have any other solution?"

She thought for a moment and said, "Nitrite poisoning tests usually involve leftover food, vomit, stomach contents, and blood. If you don't want to do an autopsy, just take the food and blood here for testing. Is that okay?"

Best Man Lu said, "Sure."

"Then find me a syringe, quickly." Jian Jing said immediately, "Nitrite and methemoglobin in the blood disappear easily. If you're late, they'll be gone." Best

Man Lu showed his capable side at this time, and immediately asked the club to send over a medical kit.

They had plenty of medical equipment—I don't know what they usually used it for—and disposable syringes were no problem. Jian Jing drew a tube of blood from the corpse, and gave a portion of the food and drink found at the scene, as well as the vomit found in the bathroom, to Best Man Lu, asking him to find someone to test it quickly.

After doing all this, half an hour passed.

Best Man Lu had a new understanding of Jian Jing. These days, apart from professionals, there are not many girls who can perform autopsies. He couldn't help but ask, "What's the next step?"

Jian Jing did not answer directly, but said, "People who are poisoned by nitrite will first experience symptoms such as nausea, vomiting, and diarrhea, and then blood pressure will drop, dizziness, and headaches. As the degree of hypoxia increases, they will have difficulty breathing, coma, convulsions, and exhaustion."

She spoke slowly to ensure that Best Man Lu could understand the meaning of every sentence.

Then, he brought out the key point: "When we were having dinner just now, the groom seemed fine."

Best man Lu looked at his watch and said, "After toasting with you, he came back to change his clothes and stayed in the lounge alone for a long time."

No wonder the groom changed his clothes. Jian Jing nodded and motioned him to continue.

"He came back around 12 o'clock. We all went to eat and left him alone to rest." Best Man Lu recalled the time, "At 12:15, someone came back and knocked on the door to go in, but the door was locked. He said he wanted to take a nap. We called him after an hour, but we didn't disturb him. Until 1:30, the door wouldn't open no matter how hard we knocked. I was afraid he would run away again, so I asked someone to unlock it, and then we found out that he was in trouble."

Jian Jing thought for a moment, frowned and said, "Generally, symptoms of nitrite poisoning will appear in 10-15 minutes, but it is not necessarily the case. It mainly depends on the method of poisoning. But it takes about 1-2 hours to cause death. Didn't you find anything unusual?" Best

Man Lu said, "I'll call that person over."

Perhaps the landlord had given instructions, and the other party was very cooperative and rushed over immediately.

Jian Jing recognized him as the best man who stayed behind, and directly called him C, saying, "Repeat the scene to me."

Best man C said, "My clothes were dirty, so I came back to change, but the door of the lounge was locked, so I called twice. Brother Yan inside told me that he was sleeping and asked me to come back in an hour, so I had to leave."

Jian Jing was particularly patient: "What did he sound like?"

Best man C hesitated and said, "He sounded a little impatient and fierce. I didn't say anything and went back."

Best man Lu glared at him, and the three words "useless" were almost written on his face.

Jian Jing asked again, "Besides his voice, did you hear anything else?"

The body was found at 1:30, and best man Lu found her at 1:40. It was almost 2 o'clock when the autopsy was performed. The time range is too wide, and it is difficult to determine what happened in the room around 12:15.

Best man C thought about it and shook his head: "I didn't pay attention."

Jian Jing sighed and asked: "Are you sure the person who spoke at that time was the groom? Did you hear it clearly?"

"Yes, how could I have misheard Brother Yan's voice?" Best man C was dissatisfied.

Jian Jing said: "Okay, it's okay."

Best man C glanced at her and asked in a low voice, pretending to be whispering but not really whispering: "Brother Yu, what was Uncle Fang thinking? He actually let a little girl investigate the case. This is too outrageous."

Best man Lu glanced at him and said coldly: "Then you go and talk to him."

Best man C immediately became embarrassed and ran away quickly.

Jian Jing wrote down a few time points in her small notebook and began to search the scene.

The scene... was a mess.

The furniture was crooked, the fruit plate was overturned on the ground, the cut fruits were scattered everywhere, and two melons were stepped on by someone, and the juice was all over the carpet, and there were several footprints.

"How many people have been here?" She was stunned.

Best man Lu said, "Something happened, so of course everyone came over. The bride fainted and was in a mess, so I can't remember clearly."

Jian Jing rubbed his temples and went straight to the next topic: "How did the groom come back?"

"He came back by himself." Best man Lu did not hide the truth, "He came back by himself at 10:40. We asked him where he had been, and he said he had something to do and had already solved it. The wedding was about to start, so we didn't ask too many questions."

Jian Jing asked very carefully, "I noticed that his watch didn't fit, what happened?"

Best man Lu was surprised again.

It's easy to say to see the details, but very few people can really do it. Few of the people he has met have this ability, so the contempt that a young man has for ordinary girls in his heart has subsided a lot unconsciously.

He replied, "He said he gave the watch to someone. Miss Jian, that watch is worth about a million yuan, so it's definitely enough to send him away." So far

, best man Lu still tends to believe that the groom went to see his ex-girlfriend.

He knows many examples of girlfriends crying and making a fuss after breaking up, claiming to come to the wedding, but without exception, they were silenced by money.

It should be the same for Fang Yan this time, so he didn't ask much, and didn't think it was necessary to ask more. On the contrary, out of the love of cousins ​​and the tacit understanding between men, he took the initiative to help cover up the matter and lent him his watch.

However, Jian Jing instinctively realized that something was wrong.

Disappeared inexplicably, came back inexplicably, and died inexplicably.

There are many mysteries about the groom.

Jian Jing thought about it and decided to sort out the case from the beginning.

The first people she inquired about were the best men, Lu Yu, A (a gay man who cut ties with the couple), B (a gay man who wanted to continue the family line), and C (a best man who stayed behind).

"Tell me everything that happened before the groom disappeared today."

They looked at each other, and A was the representative.

"Yesterday was a bachelor's night, and all of us, except Lu, stayed at my house and went to bed at about three in the morning. Lu came to my house at about seven in the morning, and we arrived here around eight.

"After we got here, we mainly helped Yanzi entertain relatives and friends and take photos. When it was about nine o'clock, when most people had arrived, we tricked Yanzi back to the lounge. When we went to look for him at 9:20, he was gone."

Jian Jing was surprised: "Why did you trick him?" "

It was the bridesmaids' request. They planned to change into the same clothes and ask Brother Yan to guess who was the real one, and asked us to help." Best man C explained.

Jian Jing understood: "That is to say, from 9 o'clock to 9:20, none of you were with him, and you didn't know what happened?"

They nodded.

"Before that, did the groom receive anything?" Jian Jing Best

man Lu asked: "You mean the gifts? They are all here. "

He took Jian Jing into the lounge and opened the closet, which contained a built-in safe. After opening it, they found that half of the closet was filled with gift boxes.

The largest box was no bigger than a notebook, and the smallest was only as big as a ring box.

Best man Lu explained that many relatives and friends had given wedding gifts, which were generally small in size but high in value, so they were all placed in the safe.

Jian Jing checked the gifts one by one.

There were fifteen gift boxes in total, and the boxes were festive and high-end, with exquisite packaging. There were wedding cards under the ribbons, signed with the names of the givers.

"Is it registered?" she asked.

Best man Lu said, "What's there to register? They are for the young couple. "

Gift money is recorded to facilitate interpersonal communication, but gifts are given by relatives and friends, and the identity of the gift only needs to be indicated on the greeting card. Other people cannot and are not convenient to pay too much attention to it.

Jian Jing nodded and picked up each gift to check it, but there was no sign that the fifteen gifts had been opened.

However, at the bottom of the closet, there was an untied ribbon.

This proved that one of the gifts had been opened.

Jian Jing guessed that when the groom put the gifts into the safe, he noticed one of them, thought it was strange or for some other reason, he opened it directly.

The ribbon fell into the closet,

but he didn't notice it. He took the gift box and sat down in front of the sofa to open it. It was this gift that made him decide to "disappear". When he left, he took the gift box and the gift away without leaving any trace. However, in his panic, he didn't notice that the red paper fell on the ground and slipped through the net.

She had just checked the waiting room and the red paper under the coffee table was gone.

But she looked for the trash can and it was nowhere to be found.

Whether it was destroyed by the groom or someone else, it proved that the things in the gift box might reveal something.
