Opening the door, Deng Chen was lying on the bed playing with his mobile phone, and when he saw us coming in, he quickly put the mobile phone away.

"Is there anything else going on at this late hour?"

"It's not too late, it's only past eight o'clock in the evening, and I have a few questions for you." I sat down on the chair next to the bed.

"Is it still the same question during the day?"

"That's right, it's why you went there, and why you stumbled and fell into the water." I kept staring into his eyes as I spoke.

He just sat on the bed and didn't say a word.

"You can't do you any good by lying, and it will be very helpful to find the murderer if you say it." Cao Yang said.

Deng Chen looked at the two of us for a long time and slowly turned his head out of the window, through the window I could vaguely see his melancholy eyes, his eyes showed unwillingness and despair.

He finally spoke, "I received a note, it was almost noon yesterday, and the note was caught in the crack of my door, so I'll show you." With that, he pulled out a piece of paper the size of a business card from behind his pillow.

The content on it, "I already know the mystery of Jiang Lei's death, please go to the plain behind the mansion in the late afternoon and wait for me, where I will tell you everything." ”

The words on it are very scribbled, but if you read them carefully, they are still very recognizable.

"So, you saw this note and went to the plains behind." I asked curiously.

"Yes, I went to the back in the afternoon when I was alone, I just wanted to go and see who knew the mystery of Jiang Lei's death......"

Deng Chen was interrupted by Cao Yang when he said this, "Who is it?" Who the hell is it? ”

"Unfortunately, I didn't see the person who wrote me the note...... I remember when I came to a bridge after walking the mountain road, I thought there was nothing wrong with it, but unexpectedly, the plank was broken, and when I stepped on the ground, I only heard a plop, and I fell. By the time I struggled and woke up again, I was already in the mansion. ”

"So who do you think the person who wrote the note is?" I looked at Deng Chen and hoped that he would answer honestly.

"I'm sorry, I just went on a whim, I don't know who this person who knows the mystery of Jiang Lei's death is?" After Deng Chen finished speaking, he put the quilt on his face, "You can go, I just want to say this today." ”

"Well, I'm bothering you so late, I wish you a good night's sleep." Although my words were full of irony, I was still very happy that he was able to save a life.

Returning to the room and closing the door, Cao Yang asked.

"Do you think the killer was the one who wrote the note or someone else? Was this case an accident? Cao Yang's words were full of tests.

"I guess it's the person who wrote the note, and I haven't decided on this case yet, so I don't dare to conclude so early. But I can basically judge that the chances of an accident are very small. Because first of all, this bridge is actually something I just visited some time ago, and it is still very strong, and I was afraid that I would break the planks at that time, but no matter how I walked, it was fine, so I can preliminarily conclude that ......"

"The broken planks were replaced by man."

I nodded at Cao Yang, "I think there is a high probability that the murderer replaced the plank, and then used this note to trick Jiang Lei to the small bridge behind, and then Deng Chen fell into the water." ”

I got up to go out of the house.

"Where are you going?"

"Let's go, go to the warehouse outside the house, it's a place to go if we want to prove our point."

Cao Yang followed me outside, and although it was always darker later in the summer than in other seasons, it was pitch black after eight o'clock in the mountains with limited lights.

I turned on my flashlight and pointed to the little house next to the longhouse, which I thought was the warehouse.

"Let's go, go there!"

When I came to the outside of the hut, I put my hands on my sides and clasped my hands to the window, and I could see everything in the house by the faint light. Tools such as shovels, axes and so on are placed inside.

"This is it." I tried to push the door open, but there were dirty tiles in the corners, and the door opened with a screeching sound.

I turned up the brightness of my phone and went inside, and I looked around for the switch of the light, but unfortunately I didn't find anything like the switch.

Cao Yang and I split up and used the light to see if there was any wooden board in the house that had been replaced. The light of the mobile phone followed the swing of my hand to the corner of the room, and I saw a black cloth covering some things, I walked over in a few strides, removed the black cloth, and saw that the things under the black cloth were just ordinary wooden tables.

"Looks like I'm taking it for granted." With that, I put the black cloth on it again.

In the ensuing hours, the two of us searched the entire warehouse but couldn't find the replacement plank.

"Hell, if our reasoning is correct, I think it's in this house." I'm a little impatient.

"Haven't you seen a suspicious one?"

"Yes, yes, but ......," I said, lifting the black cloth, and the large table was quietly placed under the black cloth.

Cao Yang stepped forward and looked carefully, his hand touching the surface of the table and refusing to take it.

"What are you doing? Massage? I asked, a little sarcastically.

"Don't you think this table is weird? I don't believe you'll touch it. ”

I slid my hand lightly across the table and looked up at my hand.

"This is? Earth? I sniffed it near my nose, "I see, this plank on this table is the original plank of the bridge, because I touched some dirt on it." ”

"That's right, as you just said, this table is covered with a black cloth, so it stands to reason that there should be no dust or mud." Cao Yang also reasoned.

"Well, you're right, I think the murderer was afraid of being discovered after changing the planks, so he put the planks on the bridge on a few table legs."

"Could the murderer still be that person?"

I thought for a moment, "I think yes, this man has committed impossible crimes before, but this time he is not so lucky, this one no one else can do." Now that we know how he created the vault, we have to find some evidence, and I think these cases will come to light......"

"So confident?"

"That's right......," I said, opening the warehouse door.

It's not a long walk back to my room, but it's been an unusually long walk, and I need to sort out some things slowly during these dark days. I already had a rough idea of who the "Avenger" was in my mind, and I was confident that I would find the only remaining evidence, because the more crimes the "Avenger" committed, the more evidence of his crimes would be left behind. Walking on the snow without a trace will never exist with me, and I glanced at the room of the "Avengers" with the thought of this......
