Within the Magic Furnace, whose silver-white body resembled a giant cauldron, a little orange-red flickered amid the hazy air. The flames seemed sparse, yet concealed terrifyingly destructive energy.
This was the large-scale spell "Blazing Sun." Once cast, it could transform into an attack resembling a small sun and incinerate everything.
Its destructive power was far beyond simply stacking ten Super Large Fireballs.
If it truly came crashing down, even the "Great Serpent Descending Form" at its peak would probably be in serious trouble.
Was this Blazing Sun strong?

"This large-scale spell is fundamentally still Duo Lai's Super Large Fireball. Its power is closely related to the energy Duo Lai inputs. If Duo Lai were already at the War General Grade or Commander Grade, the destructive power of the fused 'Blazing Sun' would be worlds apart from what it is now."
Of course, it only had the power to strike once.
Moreover, after Blazing Sun was fused, the storage slots displayed by the Magic Furnace were already full. Clearly, a large-scale spell fused from ten prerequisite spells also occupied ten storage slots.
It was impossible to fuse it again after fusion.

This was the prompt Mu Yuan had received along with the building.
He naturally understood that, but...
Did Duo Lai have any attainments in magic? No. Duo Lai's magical lethality and destructive power might be very strong, and its control might
