"Is this the new batch of drugs delivered today?

"Let’s begin the testing!"

In the Immortal Involvement Prison, the laboratory walls were covered with dozens of closely packed screens.

Every screen monitored a suspected criminal. Each was confined in a separate small room, strapped to a leather bed, with their bodies connected to various machines, and surrounded by all kinds of mechanical arms, prepared to operate on them. These criminals were too dangerous, and the Immortal Committee decided against allowing staff to interact with them directly, opting instead to use mechanical arms.

Warden Song Yin sat in front of a heap of screens, glancing at the dozens of criminals, then looking at the basket of newly arrived drugs beside him.

"Sigh, bottle after bottle, and they’re all just watery soup, could they be any good?

"The Five Red Boiling Soup, the redder it is, the better.

"Look at these bottles, what a pale color!

"Whoa, there’s even a brown one, like overheated urine.

"And a completely transparent one?

"Expert Bai Mo?

"Did he... did he switch fields?"

Director Song Yin waved his hand, resigned.

"According to the plan, each of these criminals gets a bottle for drug testing."

The assistant next to him immediately took the basket of drugs and went to inject them into the criminals.

Director Song Yin stared at the surveillance screens, noticing that some drugs were fairly simple, requiring no special handling and were directly injected!

For instance, in the top-left screen, the needle on the mechanical arm began to "whir" and rotate, vibrating at a high frequency like a small electric drill, approaching the criminal’s arm!

The new female assistant couldn’t quite understand and frowned.

"Director, why does this needle make noise, it’s too scary!

"Can’t a regular needle work?"

Director Song Yin pouted.

"No.

"These Immortal Technique Masters are different from ordinary criminals.

"Sequence Nine doesn’t matter much, but by Sequence Eight, they’re practically monsters in human form.

"A regular needle couldn’t even pierce their skin."

On the screen, blood spurted as the small electric drill needle penetrated the criminal’s arm, pushing the liquid inside.

The criminal’s stubble-covered face then twisted into a smile, completely unbothered, even slightly mocking.

The instruments and various displays next to him showed no anomalies.

After the injection, the criminal’s body showed no changes.

"Damn, and he’s just a Sequence Eight Beast Master.

"His Immortal Martial Path doesn’t even have the strongest physical attributes."

The assistant next to him was astonished.

"That’s pretty harsh!

"He was the one previously injected with the boiling liquid too, right?

"Still no reaction."

The physical resilience and healing abilities of these Immortal Technique Masters were beyond imagination, unbelievably strong!

A female assistant clicked her tongue.

"I used to watch the West State Boss killing people effortlessly, one after another."

Director Song Yin pointed to the scruffy big man on the screen, annoyed.

"If he wanted to kill someone like you, it’d be just as effortless, one after another."

They continued to watch the surveillance, seeing on the fifth screen where Professor Zhang’s drug was ready for administration.

The criminal tied to the leather bed was over two hundred pounds, a big fat man, plump and white.

At this moment, the mechanical arm operated more than twenty long needles, rotating and vibrating like small electric drills, piercing into the fat man’s head, neck, shoulders, chest, belly, thighs, and calves...

The new female assistant couldn’t quite grasp it.

"Do we perform acupuncture before using drugs here?"

The male assistant explained.

"It’s not acupuncture, it’s electric stimulation.

"These needles that penetrate deeply are electrodes.

"Professor Zhang needs to administer drugs while simultaneously electrically stimulating the criminal’s nerve synapses."

The female assistant’s eyes widened, covering her mouth, watching as the fat man emitted smoke on the screen but remained utterly still.

"Isn’t he electrocuted to death?"

Director Song Yin snorted coldly.

"Electrocuted? No! He’s just asleep!

"This 380-volt electric shock, internal to him, hardly causes any harm.

"He’s the strongest physically among the Immortal Martial Path, Sequence Eight.

"Also a desperado, his physical and mental resilience is not to be underestimated."

As he spoke, the drug was injected into the criminal’s veins by the mechanical arm.

A group of people stared at the screen’s various data readings, seeing fluctuations as the criminal gradually fell into a strange dormant state, eyes wide open, face slack, body limp, fingers outspread...

"This drug is good! Professor Zhang is reliable after all!

"In this state, the criminal cannot dream or move.

"This is what our prison needs!"

Director Song Yin focused intently, eyes fixed on the surveillance screen.

"Let’s see how long this state can last."

Behind him, his two assistants had strange expressions, feeling their leader was a bit of a pervert?

But the next moment, the criminal on the screen began twitching his fingers again, smiling, and staring into the camera, seemingly taunting Director Song Yin and the others!

This new drug’s effect wasn’t even as good as the last one!

Director Song Yin gritted his teeth, expression quickly normalizing.

"Heh, take it slow, test it gradually."

Twenty-seven Sequence Eight criminals tried twenty-seven batches of drugs.

The twenty-eighth criminal was Sequence Seven, Ye Han!

He lay bound to the bed, face filled with dread, covered in tears, eyes fixed on the whirring electric drill needle, "No! Don’t! I don’t want it... ah... ah..."

Injected, he struggled violently, tears and snot merging!

In front of the monitor, Director Song Yin pouted disdainfully.

"See that?

"That’s what you call a wimp.

"The other criminals with Sequence Eight strength dared to kill and rob, becoming notorious criminals.
