The Night Pact System I Tamed the Forbidden Academy

Victor, an aging apprentice stuck at the lowest rank of alchemy, unexpectedly awakens a formidable Night Pact System that lets him refine potions and grow stronger through pacts he chooses to make. Stranded at the chaotic Velvet Covenant Academy, he must push through one hardship after another, relying on his unusual alchemical talent to climb above those who doubted him. As he digs deeper, Victor begins to suspect that the academy's founder is quietly scheming to use the students for his own ends.
