"I don't bother Brother Lao Yu about this, I have already asked Liangchen, and she can indeed prove that you have been in the room that night, but that is only what she saw when she was awake." Li Canghai said.

Conan was a little puzzled and asked, "Brother Li, what do you mean by this?" ”

Li Canghai stared at Yu Chengen and said, "When Liangchen is awake, she can indeed prove that you are in the room, but she fell into a deep sleep for a while. And you used this time to kill Hongmei. ”

Speaking of this, Li Canghai looked at Liangchen, who was a little stunned, and asked, "Liangchen, did you fall asleep in his room that night?" ”

Liangchen couldn't have imagined that this man in black was Yu Chengen, and she nodded blankly: "I...... I slept for a while, but only half a pillar of incense. ”

Conan thought for a moment and said, "Brother Li, this is impossible. Half a pillar of incense, he came out of the room, went to Hongmei's room to kill people, and then arranged the murder scene into a secret room and returned to the room. This time is simply not enough, how can he be the murderer of Hongmei? ”

"No, I never said that it only took him half a pillar of incense to kill people." Li Canghai said deeply: "Actually, that incense is burned for Liangchen to see, because only after Liangchen sees the whole column of incense, can he determine how long he has slept when he wakes up." ”

"You mean, after he fell asleep, he deliberately snuffed out the incense, and when he was done, he broke the incense in half and lit it, and then woke Liangchen up? That's in the past. However, how did he make Liangchen fall asleep? Conan asked, frowning.

Yu Chengen laughed: "Brother Li, you said so much, it's all your speculation, what evidence do you have to prove that I killed Hongmei?" ”

"How did you make Liangchen fall asleep, this matter will be discussed later, because it involves another murder. Now, let me talk about the evidence that you killed someone. Li Canghai took out a white paper sprinkled with ink spots from his sleeve and unfolded it: "This is what I found on the writing table in Hongmei's room, I didn't care about it at first, but it wasn't until I observed the situation at the scene that I felt a little strange." ”

"What's so strange about that? It's just some random splashing of ink. Zhang Wenyuan's urn voice was authentic.

"Yes, it's some ink, but it's not a random spill, it's intentional." Li Canghai saw that everyone was confused, so he explained: "When I checked the red plum table, I found a wolf hair on the table, and the place where the wolf hair was located was exactly where these ink spots were swaying. In other words, the ink spots on the paper are formed when the wolf slams the paper. ”

"What does that mean?" Zhang Wenyuan frowned and asked.

"If I'm not mistaken, Hongmei should have been writing poems at the desk before she died, so she still has a wolf pen in her hand. However, I didn't expect the killer to suddenly attack the killer and kill him! Before she died, she left clues about the murderer. Li Canghai said in a deep voice.

"It's just a few ink spots, where are the clues to the murderer?" Zhang Wenyuan asked.

"Yes, the evidence I am talking about is these ink spots, what do you think these ink spots look like?" Li Canghai asked.

"Nan Wu Bao Bao is like a raindrop." The monk Qixin recited the Buddha's trumpet.

"Yes, it's raindrops!" Li Canghai said deeply: "What Hongmei wants to tell us is this, rain, it is Yu Chengen!" ”

"Ha, hahaha!" When Yu Chengen heard this, he immediately burst out laughing, and he laughed so intensely that tears flowed out.

"Just because of this, you think I'm a murderer? Isn't that child's play? Hahaha...... Ink drops are raindrops, I have to say that Brother Li's idea is indeed a bit unexpected! ”

Conan was also a little dazed, he looked at Li Canghai puzzled, according to his understanding of Li Canghai, Li Canghai could not make such a baseless guess?

However, he used this as evidence, which really made him feel a little puzzled.

Everyone felt that this evidence was too far-fetched, only Li Canghai's face was calm, and he didn't think much of everyone's doubts.

"Ridiculous?" Li Canghai stared at Yu Chengen.

"Isn't it ridiculous? If this is counted as evidence, then I can also say that Brother Li is the murderer, this ink is sprinkled like rain, but it is also like water, Brother Li happens to have a water word in his name, isn't it? Yu Chengen asked rhetorically.

Li Canghai shook his head, he sighed, and said, "Actually, the evidence that Hongmei left to identify you is not only here. ”

He then took out a stack of paper and said, "These are poems written by Hongmei before her death. And the evidence that identifies you is in this poem! ”

Conan looked at those poems and said in amazement: "Impossible, I've read all the poems, although these poems have different artistic conceptions, but none of them say anything about killing?" ”

"Brother Nan can't see it, because he only understands the artistic conception of the poem, but ignores the most superficial things." Li Canghai said.

"The most superficial thing?" Conan frowned.

Li Canghai said: "At first, when I was sorting it out, I was sorting it out in the order of four, three, two, one, so this evidence was pressed to the bottom, because I didn't care. It wasn't until the morning, in front of a word stall in town, that I saw someone else writing poetry, that I realized that I had made a common sense mistake. ”

"What's wrong?" Conan asked.

"When we write a poem, every time we write a poem, we put the one we write on top of the previous one, which is the order of one, two, three, four. So, the closer the time is, the more it is placed on the upper level, and that's how it is arranged. Li Canghai sorted out the papers in order, held them up and said.

"But what does that mean?" Conan was puzzled.

Li Canghai took out the first three poems and said: "I don't know if you have noticed that among all the poems, only these three have one thing in common." ”

Everyone looked at the three poems he was holding in his hand, and Conan immediately frowned and said, "These three poems have a stain. ”

"Not bad! All three poems are stained, and the color of the first is darker, the second is slightly lighter, and by the third, the color is much lighter. Li Canghai said.

Zhang Wenyuan touched his nose and asked, "Why is this?" ”

Li Canghai asked rhetorically: "What do you think, what does this ink stain look like?" ”

Everyone was puzzled, only Conan stretched out his finger and said solemnly: "Fingerprints!" ”

Everyone was stunned.

Li Canghai nodded and said, "Yes, it's fingerprints!" ”

"How can there be fingerprints on this? Whose fingerprints are they? Zhang Wenyuan asked stunned. (To be continued.) )
