The last clue was interrupted in the inn in Ha Long Town. The guest room was originally a confined space, and when Feng Yuan and Jin Shuo arrived at the room, the scene was quite well protected, and there was no trace of entering or exiting the entire room, even the windows were sealed.

Feng Yuan did not give up the clue, and Jin Shuo also realized that death was not the end.

But there are still enough time and restrictions for the investigation, Feng Yuan knows that the inn has called the police, and the nearest Southeast Asian police will arrive at the scene as soon as possible, and there is not much time left for them to collect evidence and investigate.

They must get a clue as soon as possible before the police arrive.

Jin Shuo already has a clue.

"The body temperature of the deceased has returned to room temperature, which is below 33 degrees." Jin Shuo began to inspect the body, he posed over the old man's head, his eyes were wide open, obviously he was quite frightened before he died, and there were not many wounds on his body.

"Are there only two deaths?" Feng Yuan asked.

"Two, but either one is actually a death or injury." Jin Shuo's fingers gently moved on the bald skin of the corpse, and the feeling of cooling down was more like an object, it was hard to imagine that this person had appeared in front of them vividly in the early morning.

"Throat." Jin Shuo began to analyze. "Looks like this should be the first fatal wound here, and the blade is sharp enough...... But. ”

Jin Shuo wanted to speak and stopped. Feng Yuan knew why, he glanced at it, and only felt a little sick to his stomach, although he didn't have less contact with the corpse, but the old man's wound was obviously unusual. In the throat, flesh and blood were rolled, and the trachea and tract were muddy, and even the blood vessels and nerves connected to the flesh were almost invisible.

"It's probably a sharp weapon with an inverted blade, not only lethal, but also destroys the sound of the voice in an instant, and at the same time kills the fastest, the deceased shouldn't have much time to resist." Jin Shuo only had one cruelty that he didn't say, because such a death was too unusual.

Feng Yuan nodded, but his main purpose now was not to investigate the real culprit.

"Oddly enough." Jin Shuo continued to examine the body. "Since the wound in the throat has been fatal, there is no need to add damage to the near heart, this time it looks like an ordinary wound, there is no sharp weapon with a special inverted blade, but because it is an artery near the heart, it causes the valve blood to flow back, and if the deceased is still alive, it is also a blow to death."

"What do you mean...... Is this a secondary injury after the death of the deceased? Feng Yuan frowned, he circled around the corpse a few times, and still didn't find a reasonable explanation.

"The odds are high." Jin Shuo sighed.

"Fingerprints and traces of the murder have been processed." Feng Yuan stared at the old man's corpse, judging from the cause of death alone, there was no big suspicion. "It should be a habitual offender, the answer I just got from the inn, this room was booked by the deceased three days ago, and no one should have the key except for the manager of the inn."

"Secret room?" Jin Shuo noticed the results of Feng Yuan's investigation.

"Yes." Feng Yuan replied, and then he shook his head again, reversing his reasoning. "But it can't be, these two wounds seem to tell us something."

"He killed instead of killing himself, right?" Jin Shuo also realized the problem, just one fatal injury may still have the possibility of self-killing, but two fatal injuries, and at the same time a complete incision, but the murder weapon disappeared again, is this possible?

"These two facts are inherently contradictory." Feng Yuan sighed. "The murderer in the conditions of a closed room, obliterating the victim, and at the same time disappearing without a word?

It couldn't be, his intuition told him.

"Jin Shuo, did you find anything suspicious?" Feng Yuan knew that without assisting in the collection of evidence, under the premise of monitoring and retrieving, the information he could obtain and the conclusions he could draw were very limited, and just relying on the analysis of these clues in his hands, I am afraid that this would be the end.

"You should have found something." Feng Yuan believed that Jin Shuo must have noticed something that made him have a 180-degree change in attitude.

"That's right." Jin Shuo stood up and spread his hands.

"There is no doubt about the cause of death of the body, and the structure of the chamber does not make sense at this time. I think it's very unlikely that the inn will commit the murder itself, and most importantly, the identity of this person is very special. ”

"If the people at the inn have ghosts, their reaction is strange now." Feng Yuan glanced back, and the sturdy male waiter was still blocking a group of good deeds from breaking in and destroying the scene.

"But that's not the point." Obviously, Jin Shuo didn't care about this, and he didn't have much interest in the real murderer. "Feng Yuan, you said that the corpse is more honest, this sentence is right."

"There's something weird about this corpse." Jin Shuo directly threw the conclusion to Feng Yuan.

"Strange ......" Feng Yuan knew that Jin Shuo already had the answer, but in his eyes, the most important clue was still broken here, and it was not easy to find the information about the organization behind it from this corpse.

"As I said, he has a weird body temperature." Jin Shuo said: "If the normal rate of cooling of the corpse is followed, then the body temperature of 33 degrees, the time of death should be at least ten hours or more. ”

Although Feng Yuan can be said to know nothing about medicine, after all, he has had a lot of experience when he was solving the case, and this information related to murder is even more murder. Jin Shuo mentioned the time of death, and Feng Yuan realized the problem.

"That's right." Feng Yuan slapped his thigh. "When we last saw this old man, we were guarding the door of the inn, from the time he came in to the time the case happened, it was at most an hour, how could it be that the body temperature dropped so quickly?"

"This is just the first suspicion, Feng Yuan, you have overlooked another thing." Jin Shuo was a little proud, he took a few steps around, came to the old man's corpse, and squatted down.

Feng Yuan looked at it, and Jin Shuo gently picked up a blood stain along the blood stains on the ground.

"This blood temperature is obviously hot." Jin Shuo's words made Feng Yuan puzzled.

"Didn't you say the temperature was already 33 degrees? How can blood be hot? Feng Yuan also dipped a little blood on his fingers, and then felt Jin Shuo's inference. It is true that the blood is hot, and the blood temperature is still a little higher than the body temperature, but this is also too strange.

"It's as if the blood was just left." Feng Yuan muttered. "Why is this happening?"

"It's not hard to explain, and I think there's an answer after the dissection." Jin Shuo stood up.

"Anatomy?" Feng Yuan was still puzzled, they did not have the authority to destroy the scene to inspect the corpse, let alone the equipment for dissecting without authorization, but Jin Shuo's actions could be regarded as an eye-opener for Feng Yuan.

I saw Jin Shuo take out a scalpel from his arms and immediately cut the corpse in front of Feng Yuan.

"What are you doing?" Feng Yuan was stunned by Jin Shuo's actions, but before he could stop Jin Shuo's actions, another fact was revealed in front of them.

"It's frozen." Jin Shuo cut down the arteries of the corpse, and Feng Yuan found that the muscles and blood vessels of about three centimeters inside the corpse were covered with a layer of ice scabs. "You see, don't talk about the blood temperature, it can't flow at all

Come. ”

Jin Shuo was right, he cut the old man's flesh and skin, and the blood couldn't flow out at all.

"Then this blood ......," Feng Yuan frowned. Could it be a fake? Or is it someone else's? ”

"I thought so at first." Jin Shuo shook his head, let go of the old man's body, and let it smash to the ground like an object, making a muffled sound, and Feng Yuan's heart was shocked when he saw it.

"But this approach is too stupid, a simple DNA test can find clues, it is not a cover-up at all, and compared to the series of cover-ups he did, this approach is too stupid." Jin Shuo shook his head.

Feng Yuan looked at the blood flowing everywhere, and these blood exuded a brilliant color.

"Then ...... you say" Feng Yuan wanted to know Jin Shuo's reasoning, but the latter shook his head.

"I can only think of this, the corpse is indeed strange, obviously, this killer, he did calculate something, but I don't know the reason, and I can't think of who it will be." Jin Shuo sighed and looked at Feng Yuan.

"The expert is you, and I can only provide you with this information...... Xiao Yu'er, sometimes the life of the police officer, but it is in your hands. ”

Feng Yuan fell into deep thought.

Why? Under the circumstance that the clues were extremely insufficient and there was no cooperation in the investigation and evidence collection, Feng Yuan fell into an impasse.

"Why don't you think about it first, I'll order something to eat." Jin Shuo saw that Feng Yuan couldn't find a breakthrough for the time being, got up, clapped his hands, and prepared to leave the room.

"In front of the corpse, you really have Yaxing." Feng Yuan shook his head helplessly.

"This was originally a restaurant, and I didn't even have time to eat in the past two days, so if I don't take the opportunity to have a good meal, how can I have the strength to continue to investigate the case? Isn't it, Officer Feng. Jin Shuo was about to leave the room, but Feng Yuan's eyes suddenly lit up.

"Restaurant?" He jerked to his feet, back and forth back and forth in front of and behind the corpse.

"Jin Shuo, where's the fish?" Feng Yuan raised his head, his eyes full of excitement.

"Fish? What fish? Jin Shuo was stunned, he didn't know where Feng Yuan's endless question came from, and what he wanted to express.

"When you see this guy, he should have a big net of fresh fish on his shoulder, shouldn't he?" Feng Yuan said with his hands dancing. "What about the fish? From the moment we entered the room, the fish were gone! ”

"So......" Jin Shuo also realized something. The room was as clean as if no one had ever lived there, and there was no fishy smell on this guy's body at all...... What's going on. ”

Feng Yuan said excitedly:

"The case is in sight, Dr. Jin." He immediately rushed outside the inn.

Before the police arrived at the scene, Feng Yuan decided that the murderer was still inside the inn and decided to give it a go.

"But." Jin Shuo was a little puzzled. "Why create the time lag between corpses and blood?"

"To cover up the time of the crime." Feng Yuan already had a general direction in his heart. "It's understandable, and I suspect it's not the first scene of the crime."

"How is this possible?" Jin Shuo shook his head.

"We saw this old man enter the house with our own eyes, and we saw him stay here for about half an hour, such a short time, committing murder, hiding, erasing his whereabouts, creating a secret room, and changing the scene? Is this possible? ”

"Doctor Jin, why do you think the murderer hid the fish?" Feng Yuan asked.
