Xin calmly explained: "Your great-grandfather was Parasite by the Nine-Headed Bat King for many years. His body was controlled by the Bat King, and his soul was devoured and suppressed by it. It wasn't until I just forced out the Bat King that your great-grandfather's remnant soul could finally breathe."
His tone remained even, as though he were simply stating an ordinary fact. Yet the content of his words struck heavily, revealing a truth far more brutal than Tang San had imagined.
"Originally, with your great-grandfather's soul power, he could barely control his body for a period of time and try to dispel the blood fiend energy left by the Bat King in this body. Unfortunately, your attack on your great-grandfather caused his aura to become chaotic, and he was ultimately struck by your Torrential Pear Blossom Needle. The poison invaded him, completely breaking the balance between his soul and body."
Xin's gaze shifted slightly toward Tang San, not accusing, yet not comforting either. His explanation was precise, leaving no room for misunderstanding.
"At this moment, his remnant soul has left his body and has nothing to rely on. He can no longer maintain a physical state. Before long, he will completely dissipate."
The words settled into the air like a quiet verdict.
Xin moved a fingertip, and a Red Sword flew over, lifting the Torrential Pear Blossom Needle that had been forced out of Tang Chen's body from the ground.
The motion was effortless, controlled with such precision that it seemed almost natural, as if the weapon itself obeyed his will.
The needle was completely black, and even the Red Sword that had just touched it showed signs of blackish-purple wilting, indicating it was no ordinary poison. It was likely made from a highly refined venom that Tang San had soaked for a long time, and combined with the explosive power of the Torrential Pear Blossom Needle, it was a definite killing weapon on the current Douluo Continent.
A faint, almost imperceptible corrosion spread along the surface of the Red Sword before stabilizing, further emphasizing just how potent the toxin was.
Xin took a deep look at Tang San. This child appeared righteous but was actually quite ruthless.
There was no condemnation in his expression, only assessment. In this world, ruthlessness could be both a strength and a flaw—it all depended on how it was used.
Regarding poison, Xin also knew how to use it. The poison of the Life and Death Talisman had once made Poison Douluo Dugu Bo doubt his life.
However, he never easily applied poison to those Hellish burial objects, simply because poison techniques were insidious and impossible to guard against. Once they fell into the hands of insidious people, they would cause widespread suffering.
To Xin, such methods required restraint. Without it, they would bring more harm than benefit.
Hearing this, Tang San's face turned cold, and his eyes widened as he looked at Xin, somewhat broken:
"Teacher Xin, do you mean... that I killed my great-grandfather?"
His voice trembled, the earlier confidence and ambition cracking under the weight of realization. The image of Tang Chen's final moments replayed in his mind, each detail now carrying a different meaning.
Xin did not answer. If he said Tang San killed him, even if he hadn't attacked, Tang Chen might not have survived. If he said he didn't kill him, he certainly accelerated Tang Chen's death.
Silence, in this moment, was more telling than any direct response.
"Remember your great-grandfather's teachings: be an upright person."
Xin's words were simple, yet they carried a quiet finality. He neither assigned blame nor offered comfort, leaving Tang San to face the truth on his own terms.
At this moment, the fluttering Red Sword had disappeared. Xin brushed his sleeves. More and more people were gathering around the Hell Slaughter Arena, and it was time for him to leave.
Whispers began to rise from the edges of the arena as onlookers approached, drawn by the earlier commotion. Curious eyes and cautious steps filled the space that had once been dominated by overwhelming power.
Xin paid them no mind.
Those girls would likely have many questions regarding the difficult task of managing Slaughter City.
Without another word, his figure turned, calm and composed as ever, leaving behind a scene heavy with consequences—and a young man forced to confront them.
