The APF Leader was standing behind Lucifer. Does this mean he had captured Lucifer and killed the enemies? He believed.

"Hahaha, Sir Xander! You are really great. You caught Lucifer! Amazing! May I request you something? I know I am going to be imprisoned tomorrow by the government. I only have one day left today. Can you fulfill my one wish, please? This will help humanity greatly," Doctor Rao said.

"What help?" Caen asked, smirking. "If I find it worthwhile, I might listen."

Lucifer also stood, gazing at Doctor Rao, remembering everything that he went through. There was so much anger inside him. He wanted to kill Doctor Rao right now, but he controlled himself. He had different plans. Moreover, he also wanted to hear what wish this guy had?

"Please give Lucifer to me for one day. I just want to do a few tests on him to see if we can find a way to replicate his healing or what causes it! Please let me do it! Just imagine how many lives it will save against the battle with Dungeon Dwellers!" Doctor Rao said to Caen.

"Oh? After all that, you still want to test on him?" Caen asked before he burst into laughter.

He turned to look towards Lucifer as he grinned. "Lucifer, are you seeing the shamelessness of this guy? This is the true face of humans. Go and have your way."

"Sir Xander, what are you saying? I don't understand?" Doctor Rao asked, frowning.

"Oh, you'll soon understand. And my curiosity will also end with that since I'm also waiting to see what he does," Caen said.

Lucifer started walking towards Doctor Rao in slow steps.

"You. Stop right there! Lucifer, listen to me! Don't you want to help the people? I know our test last time was a bit wrong, and I always regretted that you had died in that test. We went a bit overboard. You don't know how happy I am to see you awakened!"

"Come back to us! Together, we can work to find the best use of your abilities. And you can become like your father. You can become a hero of humans like he was! Come to me, son," Doctor Rao said as he threw the gun that was in his hand and spread his arms.

He knew that Lucifer had healing and that gun was useless against him. So he wanted to use the naivety of Lucifer to help himself. He still remembered how determined Lucifer was to be like his father. As long as he remembered that, he was sure to agree to the testing, he thought.

Lucifer walked around the table behind which Doctor Rao was standing.

"Come, dear Lucifer. Let's forget the past and look forward to the bright future," Doctor Rao said.

"Bright Future? My future only has darkness because of you. And now you'll experience the same darkness you gave me," Lucifer answered as he raised his hand and fired a weak lightning bolt at the right knee of Doctor Rao.

"Arghhh!" The lightning bolt penetrated the right knee of Doctor Rao, leaving a hole in his knees while making him scream as he dropped to the ground.

"Aaaaah!"

His scream only became louder as his left knee was also attacked, taking away both his legs. He was sure he wasn't going to be able to walk now.

"You bastard! We treated you here for five years! We fed you, and we tried to help you! Is this how you repay us! Stop right now!" Doctor Rao screamed.

As for Doctor Layman, he wasn't even moving as he was frozen in fear.

"Repay you? Don't worry about that. You will get your full repayment," Lucifer said before he fired two more lightning bolts at each elbow of Doctor Rao, making him scream even more.

The voice of Doctor Rao had turned hoarse as his face was filled with tears. His face had also lost all its color as it became pale.

'Strange. He said he won't kill by lightning. Was he lying?' Standing in the back, Caen wondered what Lucifer was doing. When he asked if Lucifer was going to use his powers to kill, he had said no.

That was why Caen had been curious about what method Lucifer was going to use. To see him use lightning, Caen couldn't help but be a bit disappointed.

After Lucifer destroyed the ability of Doctor Rao to use his arms and legs, he shifted his gaze to Doctor Layman.

Seeing Lucifer looking at him, Doctor Layman's knees turned weak as he dropped to the ground.

"I beg of you! Don't kill me! I swear to god that I will do anything you say! I'll become your slave and even your dog if you want; just don't kill me!" Doctor Layman started begging Lucifer for his life, but Lucifer seemed unimpressed.

"You'll do anything, I ask?" He asked Doctor Layman.

"I will! I swear to god I will! You won't need to ask me twice! Just don't kill me!" Doctor Layman answered.

"Alright. What I want is simple then. Pick him up in your arms," Lucifer said as he pointed towards Doctor Rao.

"Yes! Right away!" Doctor Layman hastily stood up before he picked up the body of Doctor Rao, who was still crying in pain. Unfortunately, Doctor Rao wasn't able to move his arms or legs, so he couldn't even resist now.

He was like a paralyzed man who could still feel all the pain.

"Take him to the room where I was killed. I want to see that place," Lucifer commanded.

His words were heard by Doctor Layman, who, as he had promised, didn't ask twice.

Doctor Layman started walking outside the office with Doctor Rao in his arms. Lucifer followed behind them with Caen.

'I guess I was too quick to judge. He didn't kill him with lightning. I wonder how satisfying he is going to make this revenge,' Caen thought as he rubbed his hand in excitement.

In his curiosity, he had forgotten that they needed to leave as fast as they could because a fight was going on outside.
