The door of the rented room was opened with a "ka" sound. A middle-aged man with gold-rimmed glasses walked in.

"Professor, professor..." A ray of hope appeared in Luo Shu's originally unfocused eyes. "Save me!"

Li Lirin kicked away the broken earthworm on the ground and sat down on the bed with a calm expression.

"Zhou Hang was killed by you?" The back of his glass glasses flashed.

"It's me." Luo Shu spat out a large mouthful of blood, "Teacher, didn't I tell you everything? "Zhou Yi used such despicable means to get the girl. Even if I die, I won't be able to take this lying down!"

"I thought you were angry!" Li Lirin suddenly changed the subject. "Is it worth it to do this for that bitch?"

A look of shock appeared on Luo Shu's blood-stained face. "Teacher, how … how can you say that about Yi Yi?"

"She's a bitch!" Li Lirin's expression distorted. "This woman, for money, for graduation, climbed onto my bed!"

"What did you say?" Luo Shu excitedly asked, spitting out another mouthful of blood.

"The most beautiful and best woman in your heart, Hoyi, in order to graduate successfully, I want to take her body and make a deal with me." Li Lirin took out a cigarette and elegantly lit it. "This stupid woman, she's rather pretty …"

"You're lying!" Luo Shu weakly shook his head. "I forbid you, forbid you to slander her …"

"Hmph, I am slandering her?" With a cigarette in his mouth, Li Lirin sneered. "What a pity, her thesis writing was really too terrible, and I wasn't the only one to judge it. In the end, of course she couldn't finish her career."

Luo Shu's already pale face turned even paler. He clutched his chest, breathing heavily, as if he was a fish on the shore.

"Does it hurt?" Li Lirin suddenly crouched down and puffed out a smoke ring on Luo Shu's face. "However, you won't be in pain for long. Let me help you get out of this."

He picked up the knife from the ground and pointed it at Luo Shu's face, causing him to close his eyes in the bright light.

"Teacher, you, didn't you come to save me?" he asked desperately.

"Save you?" Li Liren seemed to have heard the funniest joke of all. He threw his head back and laughed. "Do you know how long I've been looking forward to this moment? "He Yi is dead, Hu Duanyi is dead, and Zhou Hang is also dead. Now, you're the only one left!"

"You!" Luo Shuai suddenly seemed to realize something, and was about to press a number to grab his phone.

Li Liren's eyes were sharp as he conveniently gave him a kick. "Pa!" With a 'bang', the phone was thrown against the wall before falling to the ground, splitting into three parts.

"Professor Li, you … you must be teasing me, right? Quick, quickly send me to the hospital." Luo Shu's consciousness was already a little unclear.

"Hahahaha." Teasing you? "Since you're going to die anyway, I'll let you be the one to understand." "Let me tell you a secret first — this black earthworm is actually your teacher's masterpiece!"

"Ah?" In that case, did you kill all of them? Why did you do that? " he said angrily, but he was too weak. The anger made him cough violently, and his body twitched with the cough like a poor worm.

"All of you deserve to die!" Li Lirin stood up and angrily kicked Luo Shuyun. "He Yi's thesis is just passable, but she actually threatened me, saying that she wants to expose our relationship and discredit me! How could I let her! The heavens have treated me well. While I was in a dilemma, a black earthworm suddenly appeared in my laboratory. That's right, this is also my research topic — biological disposal of garbage. Earthworms have a powerful ability to digest garbage, and many places use them to dispose of trash. Naturally, my laboratory also uses earthworms as an example. But what we need is a stronger, garbage eating earthworm. Just when I was about to give up, a black earthworm suddenly appears. They showed a terrifying desire to devour, and actually devoured all the rubbish in the incubator! "

"What happened after that?"

"Later on, when I experimented with the small animals, I found out that the black earthworms only ate muscles and organs, but not bones. They would leave behind complete bones. This made me very scared and wanted to dispose of them. But now that He Yi is calling to threaten me, I made a bold decision. "

"Yi, Yi Yi was killed by you!" Luo Shu clutched his chest, his heart aching, "So we were all wrong, you were the one who killed Yi! Zhou Hang thought that Yi was harmed by that Hu Qianyu! "

"Hmph, it's because this woman doesn't know how to behave!" There was not a trace of guilt or guilt on Li Liren's face.

"Then, why did green hair grow on Na Yi's body? Was this also done by you?"

"Of course, other than me, who else would have this kind of ability?" "That green hair is a kind of bacterium. It needs oxygen to grow green bacteria. "He Yi's corpse was previously submerged in the water. Later on, it was pulled out by you guys. When the bacteria came in contact with the air, it naturally grew green fur."

So that was the case. So that was the case. Luo Shu's teeth chattered with hatred. Li Liren was a cunning fox. He had made the skeleton grow green hair, which he also misled the police into saying was the metabolite of the black earthworm. Although there were no black earthworms in the world (no outsider had ever seen one), this kind of green hair could be found. The police followed Professor Li's advice and started to search for clues from the green hair, no wonder there was no progress.

"Where's Hu Duanyi …" "How come there's no green hair on his bones?"

"That's because I didn't kill Hu Duanji." Li Lirin sneered and pointed at Zhou Hang's corpse, "He was killed by your good brother!"

"What?" Luo Shu widened his eyes in disbelief.

"Zhou Hang has an impetuous personality. As long as I give him a few pointers and 'good people' instigates him, he will naturally act on impulse."

"'Good person'?" Luo Shu let out a light breath, "You, you are that 'good person', right?"

"It's me." Li Lirin laughed out loud. "I am also the one who told you Zhou Hang's secret and advised you to get rid of him!"

"You are truly a despicable, shameless, and despicable scoundrel." Luo Shu seemed to have used up all of his strength, yet he scolded so fluently.

"Thank you for your praise." "There is no smarter person in the world than me. I will first kill He Yi, blame Hu Duanyi. Then, I will borrow Zhou Hang's hand to kill Hu Duanyi, and then I will sow discord between you two, causing you two to kill each other, causing both sides to suffer. In this way, everyone involved in this matter will be eliminated one by one. After I deal with the earthworms, this matter will forever be buried in the darkness. Hahahaha … "You must be very strange. Zhou Hang seemed to know that you were going to attack him, so he prepared in advance. That's why you spent so much effort to kill him, and even took half of your life."

Luo Shu's face turned pale. He wanted to say something, but no sound came out — he was so weak that he didn't even have the strength to speak.

"It's because the Good Man reminded him." "Even if someone finds your body, the police will still decide that you killed each other."

"Oh, really?" Luo Shu's cold voice drilled out from the ground. All of a sudden, a carp stood up. "Professor Li, I'm not dead. Are you disappointed?"

"You, you, why are you doing this?" Now, it was Li Lirin's turn to be deathly pale. He held onto the knife and staggered two steps back, "You, you, you lied to me! "You lied to me!"

A pair of ice-cold hands suddenly grabbed his throat from behind. Those hands were very thin, and did not seem to have a trace of warmth.

"Teacher, we trust you so much, yet you actually did so many heinous things. You even want to kill us all." An angry voice sounded.

Li Lirin turned his head with difficulty. It was Zhou Hang. He turned pale with fright. The knife in his hand fell to the ground with a clanging sound. "Zhou Hang. You … You are dead, aren't you?"

"Hmph, you know how to act, you know how to act 'good people', do we not know how to act?" Luo Shu snorted disdainfully, "The scene just now was only a play we put on together. The effect of the tomato sauce was pretty good. There was also Zhou Hang's' hand bone '. This was a sample of human bones borrowed from the laboratory! You despicable scumbag, you must plead guilty! "

Li Lirin's face distorted. His eyes were filled with fear, but his mouth was still as firm as before. "What crime do you admit? Do you have any evidence?"

"There is!" The bathroom door was pushed open, and a young man holding a recording pen walked out righteously.

This person was precisely Lu Xiang.

"You are … you are the person I saw last time in the hospital …" Li Lirin's face was pale. "All of this was planned long ago, wasn't it?"

He struggled madly, but how could he overcome the pincers from the two young men, Zhou Hang and Luo Shu?

"Zhou Hang, are you crazy? Don't forget, you were the one who killed Hu Duanyi! If this matter were to be exposed, you are doomed as well! "

Zhou Hang suddenly shed two streams of tears: "In my life, the biggest mistake I have done was to believe your words lightly. Just like Yi Yi, Hu Duanyi died with grievances! I will kill you for your life. I will go all out, as long as I can uncover the true mastermind behind this. I will not hesitate to pay any price! "

Li Lirin shivered. He realized that the youngsters these days were much more tenacious than he had imagined. They were terrifyingly tenacious.

Lu Xiang walked over and said to Li Lirin, who was dumbstruck, "Actually, Green Hair was a huge failure — he made me suspect you very quickly. That green hair is a biological bacterium, you are an expert in this field, isn't this exposing your identity? Later, I learned a lot of information from Luo Shu. These information were all useful fragments. By combining these fragments, one could obtain clear clues: After Hu Duanyi died, his corpse didn't have any hair on it, which was very suspicious. This meant that the person who killed He Yi might not be the same person as the person who killed him. It was also suspicious that Zhou Hang had given up on the investigation of the case just because of a threatening text message — how could he give up just because of a message when he loved Hoyt so much that he wanted to follow her? In the end, it was because of your persuasion that Luo Shu confessed everything to me, an outsider. "

"I did have the intention to teach Zhou Hang a lesson." Luo Shu smiled bitterly, "But he is my good brother. Yi Yi is already dead, so even if I kill him, it will be useless. Under Lu Xiang's persuasion, I found Zhou Hang and told him everything. "

"Luo Shu is indeed a brother." Zhou Hang's tears flowed more and more, "He showed me the text message from that 'good person'. I found out that this' good person 'was the same' good person 'who instigated me. I understand that I've been tricked by someone else, and I've become someone else's tool of murder. "

"In the end, all of you finally suspected me. That's why we acted together and tricked me into taking the bait …" Li Lirin's eyes turned red. "I'm so smart to be fooled by three little kids!"

"This is called 'The Heaven's Net is vast and the Earth's Net is vast and it doesn't leak out'." Lu Xiang stroked his chin and said, "I've read the texts of 'Good People' many times, and found out that he should be very familiar with He Yi, Zhou Hang, and Luo Shu. Furthermore, he knows a lot of the details of black earthworms. You think you're smart and use text messages and phone calls to control people, but you never thought that these things would expose you too. "

Li Liren glared viciously at Lu Xiang, as if he wanted to swallow him whole.

Lu Xiang took out a green ball from his bag and gestured on Li Liren's body.

"What … what is this thing?" Li Liren's face turned green from the reflection, making him look extremely strange.

"Soul Devouring Pearl. and you can take things that don't belong in this world. "

"What?" Something that does not belong to our world? " Li Lirin, Luo Shu, and Zhou Hang said in unison.

The Soul Devouring Orb stopped at the pocket of Li Lirin's pants. Its surface began to vibrate and emit a faint red light. Lu Xiang reached his hand in and fished out an unassuming bluish-gray rock, "This is it."

"It's mine, return it to me!" Li Lirin shouted in despair.

Lu Xiang smiled faintly. The Soul Devouring Orb flashed a green light and the grey-green rock disappeared. Luo Shu and the other two were once again dumbstruck. "Who are you?"

"I'm the underworld detective who came here to find out where this thing is."

"Underworld detective?" The three of them were dumbfounded once again.

"Could it be that you've 'premeditated' to rent our bed?" Luo Shu was a little surprised and a little angry.

"No." Lu Xiang shook his head, "Back then, it was only because a roommate of mine came here that I wanted to make things convenient for them by giving them their bed. That's why I found a place to stay on the internet. I never thought that I would encounter such a thing. "

Luo Shu did not speak.

Lu Xiang glanced at Li Lirin and said, "I think the black earthworm will appear in your laboratory. It must be this stone."

Li Lirin's face was ashen as he mumbled, "Yes, I found this stone in a petri dish later. I also experimented with normal earthworms and found out that they became black earthworms later on."

"Lu Xiang, what is this stone? How could there be such a great magic? " Luo Shu asked.

"It's an item from the Underworld — Stone of Greed." Lu Xiang's expression was a little complex, it was hard to fathom, "After an extremely greedy person dies, his soul will enter the underworld and be refined into a stone of greed. Don't worry, the stone of greed is used as a vacuum cleaner in the Underworld. Of course, as time passed, the effects of the vacuum cleaner would decrease and new stones of greed would be required. Therefore, this thing was mass-produced by the assembly line in the Underworld. I didn't expect this thing to land in the human world and turn the earthworm into a black earthworm with a strong devouring ability. "

"The black earthworms aren't scary." "What is terrible is the greed and selfishness of human nature."

"Zhou Hang, what are you going to do next?" Lu Xiang glanced at Zhou Hang.

"Surrender." Zhou Hang's eyes seemed to see through Lu Xiang's face to a faraway place, "Yi Yi is already dead, I am still just a walking corpse. Now that the truth has been revealed, I should atone for the sins that I have committed. "

His face was filled with a relaxed and joyful smile.

"Good brother." Luo Shu hugged him, "Zhou Hang, you are my best and best brother! No matter where you are, you're still my best and best brother! "

Zhou's tears once again welled up in his eyes. The culprit, Li Liren, collapsed to the ground in despair. He seemed to have aged 20 years in an instant.
