After crossing over into a world of magic, Dean Bruce was mistaken for a powerful sorcerer. Though he initially intended to sternly refuse the beautiful woman’s request to become her mentor, she offered him far too much to say no!
Completely clueless about magic, Dean Bruce had no choice but to make up spells on the spot. However, when he saw the astonishing power unleashed by the beautiful woman after chanting his random incantations, he was stunned.
The spells he had carelessly invented… could they really comprehend magic and even forbidden spells?
As Dean Bruce ascended to the pinnacle of magical prowess and became the Archmage, he candidly answered a reporter's question during an interview with the Alliance: "I never understood magic. I just made up a few incantations, that's all."
People were in awe of him—this, they believed, was the true humility of a Grand Archmage!

I Made Up Forbidden Spells, and They Actually Worked?

Whenever something is associated with the word "sacred," its rarity and importance skyrocket.

"It seems we'll need to renegotiate how to divide this."

Dean Bruce said, noticing Alita Miller's growing excitement and becoming immediately wary, suspecting she might turn against him.

Why didn't Dean Bruce consider betraying her first?

His knowledge of this world was too limited. He had no idea what the Red Sun Sacred Tree was truly capable of. If he turned on Alita Miller now, not only would he have to fight her, but he'd also have to contend with the organization backing her.

More importantly, even if he managed to obtain the Red Sun Sacred Tree, he'd need to ask others how to use it. If they had ulterior motives, it could lead to endless battles. Continuing to cooperate with Alita Miller seemed more practical; he could simply take his share of the rewards without worrying about how to use the tree.
