This is a Xuanhuan Novel

"Name?"

"Tom Marvolo Riddle."

"Gender?"

"Male."

"Hobbies, contact information, whether you have a partner, and any accomplices – spill it all."

In the Slytherin secret chamber, Horatio sat on a sofa in front of a golden table. Isis and Nephthys stood on perches on either side of the table.

Opposite him was young Tom Riddle, bound to a golden cross.

Behind Horatio, two Venomous Tentacula held up a banner that read: "Confess and be rewarded, resist and be punished."

Nut, carrying Hathor, led a group of Biting Cabbages frolicking on the immobilized basilisk.

"What exactly do you want to ask? Can you get to the point?" young Tom shouted angrily at Horatio.

"Oh ho! Got some nerve, huh? Daring to yell at me." Horatio picked up a whip beside him and lashed it at young Tom.

The soul-tearing pain made young Tom howl in agony, and he finally fainted from the pain.

"Huh? That's it? And they call you the Dark Lord? Can't even take two lashes? Peeves can take ten." Horatio said dismissively.

Ignoring the unconscious young Tom, Horatio approached the basilisk. He hadn't noticed it before when he was afraid to look directly at it, but there was a black shadow in the basilisk's head.

"What is this thing?" Horatio pulled the shadow from the basilisk's head and sniffed it. "Hmm, it smells like a soul, and a very ancient one at that. Could it be?"

Horatio quickly took out a soul nourishing potion from his bag and poured it onto the black shadow.

After pouring more than a dozen bottles, the black shadow gradually changed. An old man with a wizened, monkey-like face, wearing a green robe, emerged from the shadow. He looked exactly like the statue of Slytherin.

"Holy crap, isn't that Salazar Slytherin?" Horatio exclaimed, then began to study the soul.

"It's somewhat similar to the willpower in the Sorting Hat, but the Sorting Hat's was engraved with alchemical runes, while this one is preserved with soul power.

This soul is very weak, without any consciousness, and completely follows commands. No wonder this basilisk only obeyed the heir of Slytherin. So this basilisk is Slytherin's Horcrux, just with a different purpose than Voldemort's Horcruxes."

Horatio looked at the basilisk on the ground and young Tom bound to the cross, and quipped, "Is this like an evil Gryffindor disciple breaking into Slytherin's ancestral forbidden grounds, kidnapping Slytherin's ancestor, injuring Slytherin's divine beast, and capturing Slytherin's holy son? Tsk, this is clearly a nonsensical fantasy novel, why does it have a wuxia feel?"

Horatio took out the backup Symbiote that had been confiscated by the Ministry of Magic earlier and threw it onto the basilisk. The black, non-Newtonian fluid wriggled into the basilisk's body, starting to repair its wounds.

As its body was repaired, the basilisk slowly got up. Horatio quickly turned his back to the basilisk and simultaneously instructed Bellocan to kill it immediately if it showed any signs of aggression.

After a while, there was no movement from behind him, and Horatio received a message from the Symbiote: the basilisk had submitted.

Horatio cautiously turned around. The basilisk had lowered its head and was prostrate on the ground, its eyes also covered by the Symbiote.

Horatio breathed a sigh of relief and patted the basilisk's head. "From now on, your name is Symbiote War Serpent."
