After dying, Ryan’s soul transmigrates to another world. The God of Humanity, Alice, draws him into a mysterious space and grants him the mythical devouring magic armor, Astra.
What? There’s an old man with white hair inside it?
What? He’s awakened the most useless [Attribute-Less Origin] on the whole continent?
Even casting a fireball takes several times the mana, and breaking through requires more than ten times as much as it does for anyone else. Everyone laughs: the gods chose a useless man who’ll never advance in his life.
Ryan alone stays calm.
Because he has two cards up his sleeve.
First, Astra. It devours the mana of all things and makes it his own, letting him cast magic without limit.
Second, the mind of an Earthling.
You fight with magic? He’ll use science to make you eat your words.
Mana consumption too high? He calculates every spell down to the tiniest fraction, getting the most damage out of the least mana.
Geniuses rely on talent; he relies on calculations. Great houses rely on their legacy; he relies on having better information.
After a thousand-year wager, the Demon God sets its sights on him.
When he’s really pushed to the limit, he only has to say one thing in his heart:
“Astra, dinner’s ready.”
Then the whole place falls silent.
It's okay, keep up the good work
After reading it, it's okay. I hope the author can express the system more completely.
Personally, I think it's not bad, and the ideas are good, but the author's writing style doesn't reflect it a bit. I hope the follow-up will be better.
