The other man watched the scene in horror.
Neither of them could have imagined that this seemingly frail young man would strike so ruthlessly.
By now, his crotch was soaked, and a foul smell wafted from it.
Lu Xiao made a shushing gesture at him.
"Friend! You won't disturb my rest, will you?"
Hearing Lu Xiao's words, the man could only nod frantically.
He clamped his hands over his mouth, not daring to make a sound.
Satisfied with this, Lu Xiao turned and returned to his room.
On the other end of the surveillance feed.
The doctor spoke softly.
"The subject currently shows no unprovoked aggression! He shows no intention of leaving the box!"
Beside him, a staff member quickly recorded this information.
"Send three expendables to clean the subject's room tomorrow!"
Lu Xiao lay on the bed with his legs leisurely crossed.
Although the room was cramped and narrow, it was countless times more comfortable than the Dark Prison.
What's more, there was all the food he could eat.
Under these circumstances, Lu Xiao had no intention whatsoever of going outside.
Soon, the third day arrived.
Three humans wearing yellow vests were escorted over by a squad of special operations soldiers.
They all held cleaning equipment.
The soldiers opened the door, pushed the three people inside, then shut it.
Lu Xiao stared at the three with his dead-fish eyes, his face expressionless.
The three expendables sent this time were clearly better behaved than yesterday's two.
The three exchanged glances. Their leader was a middle-aged man.
He gave Lu Xiao a friendly look and asked,
"Sir! Would you like us to clean your room?"
Hearing this, Lu Xiao stood without hesitation and smiled back.
"Of course! Thank you!"
The three immediately began cleaning.
In truth, the room was very clean and barely needed any cleaning.
On the surveillance end.
"Confirmed: the subject will not initiate attacks on humans without cause, and harbors goodwill toward humans!"
The doctor spoke each word distinctly.
This experiment was actually meant to determine whether the Contained Anomaly harbored malice toward humans and whether it would attempt to leave the box of its own accord.
The reason there were three rooms, each enclosing the next,
was to establish how safe the subject was.
As long as the subject did not ultimately escape the largest room, it could be classified as Safe, meaning peaceful.
If the subject ultimately escaped all three rooms and acted to harm humans, it would be classified as Class D, meaning dangerous.
As for Contained Anomalies that harbored extreme malice toward humans from the outset, they were classified directly as Class D without undergoing this experiment.
For those that remained in the first room until the experiment ended, the Prison Keeper Organization would consider taking them to the real world to assist the Prison Wardens with certain missions.
The doctor's purpose in conducting this experiment was to definitively establish Lu Xiao's containment classification.
On the fourth day, the food supply to Lu Xiao's containment room was cut off.
But this clearly posed no difficulty for Lu Xiao.
He climbed through the window into the second room, ate his fill there, then returned to the smallest room.
On the fifth day, the food supply to all the rooms was cut off.
Lu Xiao was somewhat annoyed, but he was not particularly hungry yet, so he returned to his room and slept for the entire day.
On the sixth day, the food supply still had not resumed.
Lu Xiao's mood remained unchanged, and he did nothing unexpected.
Then came the seventh day.
A group of people wearing yellow vests entered the second room.
They held a banquet there.
Lu Xiao was awakened by the noise.
He looked out the window at a table laden with food of every kind imaginable.
Lu Xiao licked his lips and went out without hesitation.
Under everyone's astonished gazes,
he swept through everything on the table like a starving beast.
Then he dusted off his backside and returned to his room.
This time, he did not complain about their noise.
After all, he had just eaten his fill and did not particularly feel like moving.
The doctor took in the entire scene through the surveillance feed.
"Experiment concluded. The subject is classified as Safe, with no inclination to escape and no aggressive tendencies or malice toward humans!"
"Containment conditions: do not actively provoke him, and provide sufficient food!"
"Contained subject's ability: rapid healing!"
This information was soon uploaded to the Prison Wardens' system.
Lu Xiao's containment information was updated at that moment as well.
The doctor adjusted his monocle.
"Now there's only one final experiment left: testing the subject's combat capabilities!"
He pondered for several minutes.
"The subject is suspected to be a higher being. Perhaps a Class D Contained Anomaly could test his combat capabilities!"
"Which Contained Anomaly should we use for the experiment?"
Hearing the doctor mutter to himself, a staff member suggested,
"Doctor! Why don't we deploy Sequence 077 – Butler?"
The doctor had originally intended to use a Class D Contained Anomaly to test Lu Xiao's combat strength, but his eyes immediately lit up at the staff member's suggestion.
"A good idea!"
"077 has formidable combat capabilities, even stronger than many Class D entities, and we won't have to worry about the subject's safety!"
"Commence combat data collection for 292! Deploy 077 - Butler!"
He swiftly issued the order.
Meanwhile, staff members brought Lu Xiao to another room.
The walls surrounding the room showed clear signs of vitrification.
They had evidently undergone special treatment.
Lu Xiao still wore that same curious expression.
Ever since arriving at this base, he had found everything he saw novel.
He had never seen these things even before falling into the Dark Prison.
At this point, a staff member said to him,
"Sir, there will be a fight shortly. Do you need any weapons?"
Hearing this, Lu Xiao asked in some confusion,
"A fight?"
The staff member nodded.
"Yes, sir! This is to collect your combat data!"
Lu Xiao nodded and smiled.
"Research, right? Don't worry! I'll cooperate fully!"
After speaking, he thought for a moment.
"I've never touched a gun in my life. How about giving me a pistol?"
The staff member nodded, took out a radio, and said a few words.
Soon, another staff member came in carrying a pistol.
Lu Xiao took the pistol and stared blankly at it with his dead-fish eyes.
Recalling the military science explainers he had watched, he quickly chambered a round, then fired a shot at the ceiling.
Bang!
The bullet struck a spark from the ceiling, then ricocheted toward a staff member.
A bloom of blood instantly appeared on the staff member's body.
Lu Xiao hurried forward, his face apologetic.
"I'm sorry! I'm sorry!"
The staff member who had been shot was now on the verge of passing out from the pain.
But he did not dare lose his temper with Lu Xiao.
So he could only clutch his wound and withdraw from the room.
Outside the room, the doctor held a bell-shaped handbell with no clapper.
He gently shook the bell in his hand.
Despite having no clapper, a pleasant chime rang out from thin air.
