Shocking: The Daughter of the Ancient God Is My Deskmate!

Betta transmigrates to a parallel universe with superpowers. Subsequently, he awakens to the Furnace System. As long as he gets close to magicians, mutants, or swordsmen, he can replicate their physical abilities, merge them, and strengthen them!
Ding! Super Heat, Combustion, and Flaming Fist are integrated to give Sun Scorch.
Ding! Arc Lightning, Thunder Art, and Lightning Oculus are fused to give Divine Thunder.
Ding! Tornado, Tsunami, and Nectar are merged to give Ocean Vessel.
Ding! Tiny Fireball, Rain of Meteors, and Scorch are combined to give Forbidden Magic: Rain of Apocalypse.
It was not until one day that Betta obtains the Forbidden Curse of the Ancient God that he discovers that the campus belle sitting next to him is the daughter of the Ancient God.
