Leveling Up With Thumbs Up manhwa

My name is Um Jicheok.
An ordinary hunter assistant of the Republic of Korea.
I have been barely living, dealing with monster corpses.
But one day, after my grandpa appeared in my dream,
‘Receive thumbs ups and get awakened.’
Grandpa, is this why you gave me this name?
Thumbs up is the point!
Get thumbs up, buy skills and level up.
‘The unprecedented awakened’
The story of Um Jicheok, the strongest hunter who gets stronger through thumbs ups.
