Yuchi Chenning paced around him, as if examining a trapped beast, and said slowly:

"When we were investigating your smuggling network, we found some encrypted communication records from a few months before the incident on Sin Star 1231. There were frequent contacts with a mysterious Zerg operator. Although the other party's identity is hidden, tracing the source of the signal leads directly to your lair.

Also, judging from the descriptions of the survivors, the Zerg's attack route was strange. They bypassed your secret bases hidden in the dark corners of the planet and headed straight for the mining area and residential area. It seemed that someone had carefully planned and guided them to wreak havoc. Do you dare to say that this was just a coincidence?"

Karl's eyes were wandering, not daring to look Yuchi Chenning in the eye. His hands twisted unconsciously under the restraints, trying to break free from the increasingly tight psychological shackles.

"Even if there are communication records, it can't prove that I'm colluding with the Zerg, right?"

"Framed? The blood and tears of those survivors, the devastation of the entire planet, you want to shirk all responsibility with just one word of framed? I think you are the one who is really ridiculous."

Seeing Karl silent, Yuchi Chenning dragged over a chair. The harsh sound of metal rubbing against the ground was particularly clear in the silence.

Yuchi Chenning sat down opposite Karl, folded his hands on his chest, and stared at Karl for a long time, until the room was so quiet that only the sound of each other's breathing could be heard, and then he spoke to break the deadlock, his voice as cold as ice:

"From what I know, you are engaged in illegal biological weapons research and development in the underground base of Sin Planet 1231. You want to control the Zerg and turn them into weapons of war to make huge profits, right?"

After saying that, Yuchi Chenning stood up and threw a stack of fuzzy video data he had collected on the table. Although the picture was mottled, Carl's figure could be vaguely recognized entering and leaving the suspicious experimental site, surrounded by containers filled with Zerg samples.

She tapped on a few blurry diagrams of the laboratory's internal structure in the documents on the table. The strangely huge culture dishes and the complex, precise but illegal experimental equipment were vaguely visible in the diagrams.

Carl's face turned pale and he slumped in his chair, silent for a long time. He knew that the game was over.

"Then let me ask you again, on the eve of the Zerg outbreak, the defense system on Sin Planet 1231 inexplicably failed, the monitoring network was paralyzed, and the communication channels were all disrupted. Who was responsible for this?"

Yuchi Chenning suddenly stopped behind Karl, leaned in close, lowered his voice but full of oppression, "Don't force me to present the evidence one by one, you have only one way to go, confess."

Karl's face suddenly changed, becoming as pale as frost. Fine beads of sweat instantly appeared on his forehead, slid down his cheeks, and hit the armrest of the confinement chair.

He was silent for a long time, as if he was weighing the pros and cons. He finally spoke, his voice filled with despair: "It was me... In order to activate the Zerg test subjects and make them show stronger combat power, I bribed the people in the Sin Star Defense Control Center to shut down the system and destroy the surveillance. I thought I could control the situation, but I didn't expect... The Zerg got out of control and reproduced much faster than expected. I almost died there."

Yuchi Chenning stood up straight, crossed his arms, and looked down at Carl, his eyes full of contempt and anger: "You caused such a tragedy for your own selfish desires. Sin Planet 1231 is still a dead ruin, filled with radiation and Zerg rampant. What will you use to pay it back?"

Karl was dejected, no longer as arrogant as before, his head buried deep in his chest, muttering: "I... I know I was wrong, but nothing can be undone."

Yuchi Chenning clenched his fists, his nails digging into his palms, and hatred surged in his heart.

"You deserve to die."

Yuchi Chenning stood in front of the interrogation table. She was wearing a black tight combat uniform. Her posture was straight and agile, like a sharp blade drawn from its sheath, exuding a cold and inviolable aura.

Carl on the opposite side was imprisoned in a specially made energy prison chair. His body was slightly hunched, and his former arrogance seemed to have been completely worn away by the coldness of the cell.

Just when Carl was trying to quibble, the door of the interrogation room was knocked, and the crisp "dong dong" sound broke the tense atmosphere.

Yuchi Chenning frowned, stood up and opened the door, only to see Rong Yunqiu with an anxious look on his face, his eyes passing over Yuchi Chenning and straight at Karl.

Rong Yunqiu strode in, wearing a dark blue windbreaker. Although he had washed away the embarrassment of being kidnapped before, his face still looked a little haggard, but his eyes revealed persistence and anger.

He walked straight to Karl, stared at Karl and asked, "Karl, the Yan Kingdom was destroyed half a year ago. The country disappeared from the interstellar map overnight. The royal family was slaughtered and the people were displaced. Was it also your doing?"

"It's...it's you...you're not dead?!"

Carl's face turned pale instantly, as if he had seen a ghost. His body trembled violently, his eyes were full of fear and panic, and he subconsciously shrank back, but the prison chair restricted his movements.

He opened his mouth, but no sound came out for a long time. His Adam's apple rolled up and down. After swallowing hard, he said stutteringly, "How...how did you find out about this? That...that was a misunderstanding."

Rong Yunqiu snorted coldly, "Misunderstanding? Yan State has always adhered to peaceful diplomacy, and it is rich and peaceful, but it was attacked by the Zerg without any warning. The border defense line is useless, and the palace was attacked with precise positioning. And you happened to frequently go in and out of the gray area where the Zerg smuggling transactions were frequent before and after, and you also had close contacts with several mysterious forces. How dare you say this is a misunderstanding?"

He clenched his fists, his knuckles turning white, suppressing his anger.

If Yuchi Chenning hadn't raised his hand to stop him, he would have almost grabbed Karl by the collar.

Yuchi Chenning's eyes wandered over Karl's face, capturing every change in his expression, and added:

"Karl, the evidence chain is becoming clearer now. From the Sin Star disaster to the destruction of Yan State, your shadow seems to be behind it all. You colluded with the Zerg dealers in the interstellar black market, taking advantage of Yan State's rich mining resources, key location, and moderate military defense, to plan this tragedy of annihilation and divide up the profits, right?"

Karl's eyes dodged and he shrank back unconsciously, and the chair made a harsh sound when it rubbed against the ground.

He slumped in the chair, his eyes empty, and remained silent for a long time, as if his soul had been pulled out. Finally, he murmured:

"It's... it's me. The Yan Kingdom discovered the Zerg laboratory I hid in a nearby galaxy and threatened to expose it. I was afraid that my business would be hindered and I would be wanted by the Interstellar Federation, so I... I joined forces with the black market forces and used the Zerg to destroy the Yan Kingdom, plunder its resources, and destroy the evidence."

His voice was weak and full of regret, but no amount of repentance could make up for the countless lives lost and the shattered civilization.

Yuchi Chenning took a deep breath, tried to calm down, and sat back in his chair, his eyes still cold: "Karl, everything you said today will be recorded. Cooperate with the investigation and explain all the details clearly. Maybe you can get a lighter sentence. You can also wait to pay the price for your numerous evil deeds."

Yuchi Chenning and Rong Yunqi looked at each other, their eyes full of grief and determination.

She signaled the guards to strengthen supervision and took Rong Yunling out of the interrogation room.
