Xue Kaimo followed Qu Heng into a dimly lit hall, and the hall was filled with a strong rancid smell. No one could guess how many corpse specimens were stored here, Xue Kaimo and Qu Heng had only one idea at this time: to find the window quickly before they were smoked. The light in the hall came from the wall facing the iron door, and the outlines of several wide curtains were faintly visible in a blurred vision. Qu Heng couldn't wait to walk forward, waving his hand to signal Xue Kaimo to cover himself. Xue Kaimo nodded, holding his breath and following closely behind Qu Heng, while nervously observing everything around him. Accompanied by the sound of two people's hurried footsteps, there were a few wet crunch sounds on the ground from time to time. Several times, the two of them stepped on something, and either the soles of their feet hurt or they were slippery and greasy and almost fell, which made the scalps of the two people tighten for a while.

Finally, Qu Heng stopped, and with a wave of the long knife in his hand, he knocked down the curtain in front of him. Immediately, the dazzling sunlight reflected from the glass window covered with floating ashes, and Xue Kaimo and Qu Heng couldn't help but close their eyes. When Xue Kaimo opened his eyes again, he had already turned around, and the sunlight behind him just illuminated the distance that the two of them had just walked. Xue Kaimo had already experienced countless bloody and terrifying scenes until today, but everything in front of him still made him vomit all the breakfast in his stomach. From the iron gate to Xue Kaimo's feet, the ground was full of pools of dirty black blood that had not yet dried up, soaked in the blood water were miserable white broken bones, bursting human organs, and countless broken limbs, and just where Xue Kaimo took the last step just now, a shattered eyeball was staring at the long-lost sunlight that was shooting in front of him. Qu Heng beside Xue Kaimo was no better, his long knife stood on the ground, but his body had already bent into the shape of a lobster, and for a while, neither of the two people opened the window.

Suddenly, a low, hoarse whimper came from the shadows to the left of the two of them, followed by the sound of metal pounding on the ground, and several other curtains falling at the same time, and the sunlight flooded the entire hall like a raging flood. Xue Kaimo and Qu Heng immediately straightened up, held back the trembling of their limbs, and raised the long knife and iron rod in their hands. After the dizzying halo receded, He Xun appeared behind the rows of bloodstained operating tables, bound to an iron chair and struggling to stand up.

Xue Kaimo and Qu Heng carefully avoided the dirty and bloody debris on the ground, tossing and turning among the countless operating tables, they deliberately did not look at the mutilated corpses and half-decomposed human heads on the operating table, and forced themselves to lock their eyes on He Xun's body. When they finally walked in front of He Xun, they found that his hands and feet had been cut off, and the wounds that had not healed were covered with crimson rotten flesh, and a heavy iron chain was wrapped around his body, and several sections had sunk deep into the flesh, revealing the white bones of Sensen. Xue Kaimo and Qu Heng frowned, they looked around the hall and didn't find Dean Su.

"Where is Dean Su?" Although he was very reluctant, Qu Heng still pressed the tip of the long knife against one of He Xun's eyes, and asked in a trembling voice.

He Xun's wrinkled dirty face was full of expressions of extreme pain, but his eyes were full of tears. He Xun opened his mouth and whimpered loudly with all the strength of his body, as if begging Qu Heng to do it quickly.

"Where has Dean Su gone!" Qu Heng couldn't help but shout, he felt that if he continued to stalemate, he might die before He Xun.

"He couldn't say anything. Xue Kaimo patted Qu Heng's shoulder and pointed to the ground.

Qu Heng followed Xue Kaimo's guidance and saw that one of He Xun's severed feet was lying next to the chair, and next to the severed foot was a small piece of dead flesh that could no longer be seen.

"His tongue?" Qu Heng raised his head in surprise and looked at Xue Kaimo.

Xue Kaimo nodded, and looked at He Xun's body again. Finally, he found a brass key on He Xun's chest, the key chain was made of something that looked like a belly, hanging on He Xun's neck that seemed to be broken at any time. Xue Kaimo took a deep breath, stretched out his hand and pulled down the key, and the light yellow keychain was also broken, and it was soft and slippery on Xue Kaimo's wrist.

"Key?" Qu Heng's tone was not so much surprised, but rather admiration for Xue Kaimo's decisive actions.

Xue Kaimo didn't have time to pay attention to Qu Heng, he nervously flicked his wrist and threw the mud-like thing to the ground. Then he calmed his mind before holding the key up to his eyes. It was just a very ordinary brass key, and there was nothing special about it except for the black and red filth on it.

"Control room or blood bank?" Qu Heng asked again.

"Maybe, but why did Dean Su leave it here?" Xue Kaimo fiddled with the key back and forth in his hand in confusion, turning his head to look at He Xun in the chair.

He Xun seemed to have a lot to say. He kept shaking his head back and forth, muttering indistinctly as his mutilated body struggled, but each movement of his body only made the chain sink deeper and deeper into his body, and in a moment his eyes burst in pain, and two gray-white eyeballs almost burst out.

Qu Heng raised the long knife in his hand and looked at Xue Kaimo with inquiring eyes. Xue Kaimo nodded helplessly. With a piercing reflection shining above the blade, He Xun's head fell to the ground, and the two eyes that were finally relieved finally burst out and rolled towards the corner closest to He Xun's corpse.

"Where did Dean Su go, could all of this be deliberately designed by him?" Xue Kaimo turned his head and asked Qu Heng.

"In any case, we must rush back to Building 2 now, the time for the decisive battle is approaching. Qu Heng glanced at his watch and said to Xue Kaimo.
