By reviewing the case at the crime scene, Qin Feng basically restored the process of the case.

He knew how Tang Ren's fingerprints on the murder weapon came from.

He also figured out that the murderer actually hid under Dan's bed a week in advance, and when Tang Ren got here, the murderer had already killed Songpa. The figure Tang Ren saw through the glass before he left was actually Songpa's body.

He also knew how the murderer left the crime scene. The box that Tang Ren shipped out at that time was not a sculpture, but the murderer himself.

He asked Tang Ren to pick up the courier, and he sent himself out by courier. By the way, he framed everything to Tang Ren, killing two birds with one stone.

Maybe even take it with the gold.

Tang Ren was so shocked that there was nothing to add. He never imagined that things would be so complicated.

"In Song, Song Ye Jingwu's "The Secret Room of the Seeker", the murderer hid in the patio for a month in order to kill people." Qin Feng said to Tang Ren, "Holmes said that after eliminating all the impossible, the remaining one is incredible. It's the truth."

"But, the introduction doesn't make sense..." Tang Ren scratched his head and frowned, "When I left that night, Songpa was clearly working, and I heard the sound of the cutting machine."

Qin Feng smiled: "I, I just asked you to review the case, you, you said there is something on that table?"

Tang Ren glanced at the table and said, "Audio, I remember, there is a stereo there."

"But, but it's gone now." Qin Feng said.

"It must have been taken by the police." Tang Ren said.

"But in the case file, there is no mention of that sound at all." Qin Feng said.

"Then, then maybe it's because the police who are handling the case are taking the lead!" Tang Ren thought for a while, and said, "Siam's police officers are not of high quality. They often do tricks."

"Yes, there is such a possibility." Qin Feng took a deep breath, "but, but there is another more reasonable possibility."

"What?" Tang Ren asked.

"God, mysterious man!" Qin Feng's eyes were deep and he said solemnly, "If my guess is correct, then the sound you heard that night was not the sound of Songpa's work at all, but the pre-recorded audio. !"

He paused and looked at Tang Ren: "The murderer got into the box while you were filling out the documents, and then connected to the stereo via Bluetooth. The stereo is just outside the window of the operating room. When you hear the sound, you will see Songpa as soon as you turn around. The shadow of the corpse, and the sound you heard came from this direction, you would think it was the sound of Sompa’s work.”

Tang Ren was stunned, slapped his thigh and shouted, "I've got a chicken! The mysterious man's chicken is a key evidence of the sound system, so I took it away!"

"No, that's right!" Qin Feng shook his head, "For example, if this speaker is a Bluetooth speaker with a memory function, maybe it's the only evidence that the murderer came here."

"Mysterious Silver took it away, and it must have been destroyed!" Tang Ren said bitterly, "I have long ago that the little white face with the surname of Jidao He is not a thing! He must be Jidao Axiang and he still has me in his heart, so he Jealous of me, he deliberately destroyed all the evidence, leaving me speechless, so I had to take the blame for the real murderer, and he also blinded the real murderer, making this case machine washable!"

Qin Feng was slightly silent.

In fact, by now, the identity of the murderer and the identity of the "mysterious man" are already obvious. Qin Feng is sure that the murderer is that Li, and the mysterious man is He Xie.

However, Li's motive for murder and He Xie's motive for destroying the evidence, Qin Feng was completely unclear.

It doesn't matter if the motive is unclear. All the truths that have been restored in the key case are just his speculations, and they can't come up with any evidence.

And the most terrible thing is that if He Xie really killed her adoptive father Li in front of Sinuo, then this He Xie is an extremely dangerous person.

Qin Feng still remembers that He Xie came to Taijing at the same time as him, and the night this person came to Taijing, he stayed at Tang Ren's beautiful landlady, A Xiang. The next morning, he went to Tang Ren. Investigate Mr. Yan…

When Qin Feng thought of this, he suddenly felt a chill in his heart. He Xie entrusted Tang Ren to investigate Mr. Yan. Could he actually use Mr. Tang's hand to kill Tang Ren?

He suddenly thought of going to hand in the task that night, He Xie stabbed Tang Ren with a finger, Tang Ren didn't get up for a long time, and he couldn't even speak the pain.

At that time, Qin Feng thought Tang Ren was pretending.

But thinking of Li's death, the shadow captured by the surveillance camera, and the teacup that stunned the big fool at Ah Xiang's house, Qin Feng is now basically certain that this He Xie must have something he can't understand at all. Special skills!

Thinking of Mr. Yan's attitude towards He Xie that night, Qin Feng suddenly broke out in a cold sweat.

He didn't know what relationship between Mr. Yan and He Xie, but if He Xie could even handle Mr. Yan...

It was only then that he realized that no matter how far he investigated, facing him and Tang Ren was a mortal situation!

Maybe before the police catch them, he and Tang Ren will be silenced!

"What's the matter with you?" Tang Ren asked worriedly, looking at Qin Feng, who had a gloomy expression and was sweating profusely.

Qin Feng looked at Tang Ren with straight eyes.

"We're dead," he said.

"Damn it!" This is what Tang Ren didn't want to hear the most, especially if it came from Qin Feng's mouth.

"The truth has been found out by you! Now that the evidence is about to be found, we will be out of the game. You continue with me now, and we are settled?" Tang Ren was a little exasperated, "He will definitely leave traces when he comes to Jili, I If you don't believe us, we can't pull his fox's tail!"

"No, it's useless." Qin Feng took a deep breath and managed to regain some calm, but his face was still a little pale.

Smart people tend to think a lot, and people who think a lot are more afraid of death.

They are not only afraid of death itself, but also of the more terrible consequences of death.

"Brother Tai and Tai said that the police station was stolen. They checked all the surveillance cameras and checked every inch of the scene, but they found no evidence." Qin Feng said, "I also carefully watched all the surveillance here~www.mtlnovel .com~ There is no video of the person surnamed He going in or out at all, and apart from the gate, the only access to the outside world is there!"

Qin Feng pointed to the ventilation fan to the side.

Tang Ren hurriedly turned his head to look over.

"I saw it just now. The ventilator is installed in the middle of the two walls, and the distance between the two walls is less than 20 cm." Qin Feng said to Tang Ren, "And it can only be disassembled from the inside, but there is a trace there. None left!"

"I'm chicken!" Tang Ren's eyes widened, "He knows the legendary bone-shrinking technique!"

"Just, even if he knows, how, how to prove it?" Qin Feng said, "We have no evidence, let alone his motives. Even Li's motive for murder, we can only rely on guesswork."

"Are we really done?" Tang Ren muttered with despair in his eyes.

"Unless..." Qin Feng hesitated.

"What is Qu Fei?" There was a glimmer of hope in Tang Ren's eyes.
