Doctor Layman carried Doctor Rao to the same lab where Lucifer had been killed last time. Helpless Doctor Rao couldn't even move his arms and legs to resist, but he did keep begging Caen, who he still believed to be Xander. 

"Master Xander! I know I was rude to you before, but you can't do this. You can't hurt a weak human! Please save me. Let the government deal with me! Don't help injustice here!" Doctor Rao begged Caen. 

"Don't worry; I'm not helping any injustice here. On the contrary, the injustice is asking me for help, and I'm saying no," Caen answered as he ignored the pleas for help. 

It didn't take long before Doctor Layman reached the lab. Lucifer also remembered this place. This was the last room he had seen in the facility, and he could never forget it. 

"Can I put him down for a minute to open this door?" Doctor Layman asked Lucifer.

"No need," Lucifer said as he stepped forward and broke the door with a kick before he entered inside. 

Caen also entered the lab, but he didn't forget to say something to Doctor Layman before entering.

"You could have been in the place of that door, so don't do anything stupid and listen to him," Caen said.

Doctor Layman was already covered in sweat because of the fear, but this time, he was even more scared as he stepped inside the lab, wondering what was going to happen. 

As he entered the lab, he noticed Lucifer standing near the bed, staring at it. 

Lucifer couldn't help but touch the bed. It seemed like everything had happened just yesterday when he was brought here and told to lie on the bed.

He looked at Doctor Layman and said, "Place him on the bed."

Doctor Layman hastily stepped forward and placed Doctor Rao on the bed. 

Doctor Rao was starting to have a very bad feeling as he was placed on the bed. He believed he understood what Lucifer was going to do, and that thought was frightening. 

"Arghhh! Lucifer! Listen to me! Please stop! If you do this, there's no going back! Don't become evil, or your parents' legacy will be destroyed! We can solve our differences through talking! I will do anything you say! Just forgive me this once! You're still alive, so nothing is lost! Don't make this mistake!" Doctor Rao screamed in fear. 

Not only Lucifer, but he also continued begging Caen. "Xander! Please help me! I swear to god I will change! I won't do anything wrong again!" 

Unfortunately, not a single person here was going to listen to him. Only Doctor Layman was prone to listen to him, but even he was too scared for his life to go against Lucifer. 

"Attach all the wires and machines to him that you had attached to me that day."

As Doctor Rao was placed on the bed, Lucifer gave his following command to Doctor Layman. 

At this point, even Caen understood what Lucifer wanted to do. 

"Hahaha! Bravo! I like this one!" Caen said, laughing out loud. "This is a pretty good idea!"

Doctor Layman had also understood what was happening here. He still hoped that since he was helping Lucifer, he was going to be safe. 

Moreover, it was Doctor Rao that had done everything. He was only listening to commands last time as well. It wasn't as if his crime was that grave. 

He attached the machines to Doctor Rao's bodies, including all the wires. He also picked up a head-band-like object that was connected to a machine behind him and placed it around Doctor Rao's head. 

"Today, I am incharge of this facility! Start the test! I want to see how much pain he can handle. If I remember correctly, you all called it the Pain Index, right?" Lucifer asked as he stood near the laptop from where Doctor Layman had controlled everything last time.

Doctor Layman was already prepared for this demand since it wasn't hard to guess after Lucifer asked to place Doctor Rao on the bed here. 

He turned on the laptop and pressed a few buttons before he looked at Lucifer and said, "Everything is ready, Master."

"Good, on my count," Lucifer said, repeating the words that Doctor Rao had said when Doctor Layman had told him that he was prepared to start last time. 

"3... 2..." Lucifer began the count.

Hearing the count, the fear of death started taking even more effect as Doctor Rao's heart churned in pain. 

"Please stop, for God's Sake!" Doctor Rao yelled. 

"Today, everything will happen for my sake. I'm your only god today," Lucifer told Doctor Rao before he resumed the count. 

"1... Begin!" 

Doctor Layman pressed a button on the laptop as soon as Lucifer finished the count, and with a slight sound, the process began.

"Aaaa!" Doctor Rao screamed as loud as he could with the heart-wrenching pain coursing through his body. He felt like his body was being torn into shreds, and every cell of his body was breaking apart at a rapid pace.

He kept screaming, but the torture didn't stop. Instead, it went on and on for what seemed like an eternity.

"Heartbeat rising rapidly. The pain index reached 10 percent. Cell destruction has begun," Doctor Layman declared as he read the data on the screen. 

In his mind, he was amazed. 

'When we tested on Lucifer, Cell Destruction began at a sixty percent pain index. But with Doctor Rao, it started at only ten percent pain index.' he thought.

"Stop it now! My cell destruction has begun! I beg of you! Please save me! Save my life!"

" If you don't stop, my entire body will become useless! I am asking for forgiveness. Arghhhhh! Stop! It hurts so much!" Doctor Rao screamed in pain as he begged for them to stop this torture, completely forgetting that he had put Lucifer through much more torture than this. 

He was only at ten percent Pain Index at the moment.
