When he was twelve years old, his parents were killed by nobles and his sister was taken away by a mage.
He knelt in front of the grave and swore: Become stronger, find his sister, and make his enemies pay the price.
There is no golden finger, no grandpa. Mediocre in talent and humble in origin. All he can rely on is a pair of eyes and a life - to observe every flaw of his opponent, withstand every knockdown, and then get up.
From the hammer of the baggage train to the blood ring of the other world, from the mortal cannon fodder to the master of the temple.
This is a story about civilians working hard with their lives.
The world is unfair. But he'll make it fair.
(It's really well written, why don't you read it? The first three chapters are introductions. If you don't want to read them, you can just go to the back)
