Spell Counter and Spell Resonance, Have You Heard of Them?

Mu Yan is a high school student who makes a living writing novels. A few days ago, this interface popped up on his computer:

"Do you want to understand the meaning of life? Do you want to truly live?"

"Yes/No"

He was stunned for a second, then immediately clicked the X in the upper-right corner.

Then his computer exploded.

Then he entered the Main God Space.

After that, he survived by the skin of his teeth, overcame countless hardships, and finally gained the world's strongest ability: Spell Counter plus Spell Resonance. Would you believe the combined effect is Spell Reflection, and he can cast it whenever he wants? Mu Yan became invincible just like that. He says he's pretty helpless about it, honestly.
