I Took Up Online Gaming After Retirement

What? Why do I have so many materials and items? That's right, I have a hidden class.

Why are both your physical and spell damage so high? Sorry, I have two more hidden classes, too. Oh...

Talents? Two top-tier innate talents aren't enough? Then I'll evolve them all!

Pets? You started with just a five-tailed fox in the beginner village. Wait, what's that one over there? There are too many to introduce them all!

How do you become invincible? Easy: a miraculous opportunity and godlike skill!

Equipment? Skills? Stop asking, stop asking! You have way too many questions!

The strongest effects, talents, techniques, classes, equipment, skills, and pets: whatever it is, he wants it all!

He's invincible. Everyone else can do as they please!

(The setting has quite a lot to cover, so the pacing will be slower at first.)
