Li Ju fell to the ground, his body curled up in a ball, dark red blood flowing from the back of his head, and the syringe and the plastic tube falling beside him. Ke Tong rescued Xue Kaimo from the cart, and then walked out of the hall without a sound and walked into the dark tunnel.

Xue Kaimo ignored Ke Tong, he squatted beside Li Ju and picked up the syringe. Li Ju's face was as pale as paper, and a pair of eyes that were losing their luster looked at Xue Kaimo with fear, his lips trembled, as if there were still many words left unfinished, but at this time, Xue Kaimo no longer needed his explanation.

Xue Kaimo inserted the syringe into the wound on Li Ju's head, and after drawing a tube of blood, he inserted the syringe into the plastic tube on the ground. The other end of the plastic pipe connected to the iron door in the middle of the hall, and a glaring red line slowly pushed towards the iron door until it entered the interface of the plastic pipe under the iron door. The syringe was pumping Li Ju's blood back and forth between Li Ju's head and the plastic tube, and Xue Kaimo's face was expressionless during the whole process, and his eyes seemed to be covered with a gray film. Finally, Li Ju turned into a withered corpse, leaving a pool of black blood under the corpse's head. Xue Kaimo stood up and turned around to see the two words above the iron gate: "Blood Bank". A strange smile appeared on the corner of Xue Kaimo's mouth, but then he fell to the ground, sweating as if he had entered a steamer.

Ke Tong reappeared at the entrance of the hall, holding the body of Lingzi in his arms.

"Lingzi, I have finally avenged you, and you can rest in peace. Ke Tong put down Lingzi's body in front of Li Ju, and then he stumbled towards Xue Kaimo, and stretched out his hand to choke Xue Kaimo's neck.

"I'll just ask you one thing, do you have anything to do with everything that happened?" Ke Tong's eyes were bloodshot, and behind the bloodshot was a faint murderous intent remaining.

Xue Kai looked at Ke Tong in a daze, his face had turned purple and red due to suffocation, but he still had the strength to shake his head, and he still had the strength to show an innocent expression in fear.

Ke Tong let go of Xue Kaimo and sat beside him.

"Don't blame me for being ruthless, since Lingzi's death, I have made up my mind to kill Li Ju to avenge her. Everything started because of Li Ju, and although I have no evidence to prove that he planned the whole incident, I have always had a strong feeling that Li Ju must have hidden many ulterior secrets. Until one day, when I was following him, I discovered this tunnel, and saw with my own eyes that he killed the teachers in various ways, drained the blood of each corpse, and finally transported the blood to this blood bank. Ke Tong said to Xue Kaimo.

"Why did he tie the ears, nose and mouth of those corpses?" Xue Kaimo asked.

Actually, that was the last step, and before that, everyone was tortured by him, and then suffocated to death with their noses and mouths gagged. I can't guess the reason for the blocked ears. After Ke Tong finished speaking, he stood up, picked up Lingzi's body and put it on the trolley that Xue Kaimo had just laid. "I'll find a suitable time to burn it, after which I'll kill myself. It's not because I love Reiko too much, but because I can't stand what is happening and going to happen here, and I'd rather stay here with Reiko than go back to Earth to face the death that can happen anytime and anywhere. When the time comes, I beg you to help me one last time: burn me. Ke Tong couldn't stop crying when he said this.

At this time, the corpse of Lingzi, who had just been placed by Ke Tong, seemed to move suddenly, and the trolley made a muffled sound and shook lightly.
