The System Teaches You How to Be Human

Si Yisi understood Tru’s current mindset all too well.

He was trying to deceive himself, yet deep down, he had already started to believe the truth; hence his complete descent into madness.

Moreover, Tru’s body, which had already been eroded by Zerg genes, was gradually undergoing a fundamental transformation under the influence of the homogenizing serum.

Nine times out of ten, what Tru was thinking about now was how to release the Zerg into human-populated areas, ensuring that the likes of Si’an and those “lowly commoners” perished without a grave.

Si Yisi found the Zergs’ genetic influence to be truly mind-numbing. Did Tru really have to rely on the Zerg for something as simple as revenge?

All he could say was…

Good job!

Although the original owner’s wish had been nearly fulfilled, the chance to slaughter a few more Zerg was simply too tempting. Just thinking about it made Si Yisi eager to act. He followed Tru closely, using the specialized equipment provided by Huo Jinren to record every single one of his actions in full detail.

This time, the plaintiff at the Supreme Court was Huo Jinren himself. For the first time, he had mustered the courage to expose those people and Tru’s crimes! He had struggled with hesitation, but in the end, he chose to face the truth bravely.

“Huo Jinren will achieve great things in the future. What do you think, Ah Tu?”

Ah Tu let out a hissing sound. A finely crafted metallic flower was pinned to his head; an eternal bloom, its bold and unrestrained petals mirroring Huo Jinren’s unwavering determination.

He would be fine.

Si Yisi was sure of it.

He had never misjudged anyone.

Tru tried every means possible to escape from the Kaz Empire. To make his getaway, he even purchased the cheapest, most dilapidated lower-class cabin and boarded the ship in full disguise.

Inside the foul-smelling compartment, Tru fanned himself desperately, waving his hands like a large fan while pressing a mask tightly against his face. But no matter what he did, he couldn’t block out the suffocating stench that seeped into every corner.

“Damn… these filthy commoners. Disgusting.”

Sitting beside him, Si Yisi, also in disguise, casually pulled down the brim of his hat and absentmindedly read a line from an old, tattered newspaper.

“We can now confirm that the Kaz Empire’s Third Prince, Tru, is nothing more than a lapdog serving the Zerg.”

“Filthy… disgusting!”

Tru’s ears twitched as he caught those words. This time, his voice rose slightly in volume, his tone full of contempt.

The lower-class cabin was filled with a chaotic mix of people, each on edge at all times. Even the faintest buzz of a mosquito would be noticed; let alone Tru’s voice, which was as loud as a broken loudspeaker.

And here he was, openly insulting them in their own territory?

He was courting death.

The moment Tru finished his furious outburst at the “filthy commoner” beside him, the other passengers, huddled together in the cramped space, all turned their heads in unison to stare at him.

Their gazes, devoid of kindness, locked onto his face like a silent, eerie stage performance. The synchronized reaction carried an unsettling air, as if something truly terrifying was about to unfold.

“What did he just say?”

“Commoners…?”

A chilling sense of foreboding crept over Tru. Before he could react, someone yanked a long strand of hair straight from his scalp!

Pain!

It felt as if his entire head was being ripped apart!

He had just kicked a hornet’s nest. The so-called “filthy commoners” swarmed forward, their eyes bloodshot with rage, carrying the air of a mob ready to tear someone apart.

Their fighting style was nothing short of ruthless—like street brawlers who knew exactly where to strike for maximum pain. They didn’t bother with elegance or restraint; wherever it hurt the most, they went straight for it without hesitation!

Tru had no choice but to curl up, using all four limbs to shield himself. He was utterly pathetic.

Someone yanked his hair again and shouted, “You think you’re better than us? Aren’t you just as much of a ‘filthy commoner’ now?!”

Another person, without hesitation, dumped a bowl of leftover soup over Tru’s head, drenching him in greasy broth and vegetable scraps.

Crude insults deserved crude retaliation. Unlike the nobles, who played their games in the shadows, these people didn’t waste time scheming. If they didn’t like someone, they beat them up—simple as that.

Si Yisi watched as Tru, now face-down on the floor, was forced to endure the curses and attacks from the other passengers while desperately trying to inch his way toward the exit.

Si Yisi blinked.

Then, without hesitation, he reached out, squeezed into the crowd, and lifted Tru’s beaten, crumpled body right off the ground!

Now, the punches rained down on Tru’s face like raindrops, and Si Yisi’s “prank” succeeded. With a hint of amusement in his voice, he spoke to Tru.

“I’m giving you a hand, no need to thank me.” His voice had been disguised, sounding like a mischievous young man, his cheerful tone lighting up the entire cabin.

Si Yisi even used his mental powers to temporarily block out the curses of the passengers, ensuring his words reached Tru’s ears clearly.

Tru staggered from the blows, spitting out a bloodstained tooth. He recognized the voice and angrily scanned his surroundings.

Thud!

His eyes blackened.

Clang—

A person who had recently made headlines grabbed Tru’s rat-like tail.

“What the hell is this?” he muttered, then yanked the tail roughly.

“Get lost! Get the hell away!” Tru screamed in madness, but his voice was drowned out by the curses and the sound of fists hitting flesh. He raised his tail to signal an attack, but his mental powers seemed stuck, unable to move as if trapped in a swamp. The so-called commoners were now playing with his tail like a toy!

Finally, after enduring the chaos, Tru had a swollen, bruised face and a searing pain in his tail.

Just as he stepped out of the cabin, Si Yisi casually extended his foot and tripped him.

Clang!

Tru’s forehead collided with the door again, swelling up like a red bun. But, having been beaten to the point of fear, he only cursed and stumbled away in a disoriented escape.

His mental powers had definitely weakened due to the Zerg transformation… but if he injected human genes, he believed he could return to normal.

Tru went to the slave market and bought a live person, then began preparing for his “human transformation” experiment.

But Si Yisi had noticed the subtle fear in the soldiers who obeyed Tru, so he singled out one who resembled him slightly and whispered to him. “The person you serve wants to extract human genes for himself. He’s experimenting with slaves right now—”

“But if he finds that the slaves are useless, do you think he’ll target strong soldiers like you?”

The young soldier, uncertain, trembled in fear.

Every 3 months, the army took a small sample of soldiers’ genes to ensure that no Zerg had infiltrated.

Even the small extractions caused excruciating pain; He was now wavering. Si Yisi gave him a bribe to seal his silence, “I hope you’ll temporarily leave your post.”

“…Alright. I agree,” the young soldier trembled, still haunted by the imagined agony of bone-deep pain.

After spending so much time together, it was clear to everyone how ruthless Tru was. If not for Emperor Clint’s oversight, Tru would have undoubtedly caused chaos throughout the empire for his own selfish gain.

And he cared nothing for the soldiers, who had no family ties. In Tru’s eyes, they were expendable; easily discarded tools.

No one wanted to die. After making his promise, the young soldier quietly approached his comrades, the ones he had grown close to, and subtly turned them to his side; one by one!

This was something Si Yisi hadn’t anticipated, but everything was going in the best possible direction!

***

The day of Tru’s experiment soon arrived. He was impatient, with no time left to waste.

He believed that if he appeared in front of the people, as a human, at the critical moment when they were facing a Zerg crisis, they would worship him like a god!

With that hopeful mindset, Tru took a specially made syringe and slowly approached the slave he had bought.

His limbs had sprouted Zerg-like grey exoskeletons, and his gait was strange; like a drunk man, unable to control his steps, his body swaying as if about to fall to the ground any second.

Tru grinned, revealing sharp teeth, drooling with anticipation as he gazed at the slave, unaware of his own desire.

The slave trembled and tears streamed down his face, but the ropes binding him were gently undone by a hand. Si Yisi lowered his head and looked at the slave. He was a small, frail boy. “Go quickly.”

Si Yisi turned his head to look at Tru, who was now under the illusion caused by his mental powers, seeing himself as the target for gene extraction.

Tru impatiently plunged the needle into his skin, aiming directly for vital spots with each jab. He felt no pain. His Zerg eyes were now filled with excited crimson, and his body was covered with dense, bloody holes. He was ruthless with himself, stabbing the needle deeper, making the wounds tear even more severely.

The way Tru treated himself sparked a flame of anger in Si Yisi. If it had been the slave who was being subjected to the gene extraction, Tru would have tortured him to death.

“Th-thank you!”

The frail boy slave stammered his thanks, then glanced at Tru with a look of lingering fear. After thanking him, he immediately fled. If he didn’t run, no one would be able to save him.

To the boy’s surprise, when he left, the patrolling soldiers had vanished.

The boy looked up at the large screen, which was broadcasting an urgent, reckless bounty on Tru’s head. Tears in his eyes, he went to report it.

Good and evil are eventually repaid, and the boy hoped Tru would face true justice.

***

Tru, still under the influence of the mental manipulation, struggled to extract his genes. His body grew weaker, and the Zerg exoskeleton was rapidly shedding due to his rough movements.

When he finally felt he was done, he stopped extracting the genes and coldly ordered a soldier standing before him.

“Drag him out and dispose of him!”

Si Yisi thought to himself. You really do need to be disposed of, but… I’ll wait a little longer. I’m looking forward to it!

Crash!

Si Yisi stood outside, knocking out each medical staff member who received orders. He tied them up with ropes, gagged them, and threw them into a hidden corner.

Next, Si Yisi changed into a white medical coat and stepped inside.

“Why is it just you?” Tru looked up with a raised brow, his expression critical. But what affected his mood more was the frenzy and excitement of his revenge.

Si Yisi calmly replied, “According to the best solution we discussed, having one person complete this treatment will yield the highest success rate. I hope you understand.”

“Good, good, good!!” Tru laughed, ignoring the discomfort Si Yisi’s presence caused him. “Quick, start the treatment! Or I’ll kill your family!”

Indeed, Tru was using the medical staff’s family as leverage to force them to proceed with the treatment!

Si Yisi pretended to be frightened, pausing briefly before responding, “Yes… I’ll make sure you’re satisfied.”

He wore a medical mask, his eyes sharp with intent. At that moment, Tru was nothing more than a fish on the chopping block, ready to be slaughtered.

Tru, drugged with anesthesia, slept for a while. When he awoke, the surroundings were bathed in blinding red light, which instantly made his tension rise to the extreme.

“Sorry… I did my best. You’ve completely transformed into a Zerg. There’s no way to return you to human form,” Si Yisi said.

In reality, Tru’s efforts had always been futile. Why had he believed that other medical personnel could surpass the skill of the Kaz Empire’s imperial doctors?

Even if there were indeed more powerful doctors hiding in the world, such good fortune would never fall upon someone like Tru!

“What?!” Tru struggled to get up from the bed. “I’ll kill you, kill your family and chop them up to feed to the dogs! No, before that, I’ll drag them all to the brothel and sell them!!”

He swung a Zerg claw at Si Yisi!
