The Great Wall

Ren is an orphan who is trying to survive on his own in the city. He finally decides to try and join the Adventurer's guild to earn a bit more money but almost loses his life in the first quest. A mysterious person saves him, only to leave him to die at the city gates!

Fair warning, this is a story about a guy who is surrounded by women who are taller and stronger than him. If you are looking for a story where the male lead takes charge and protects the women, this might not be the story for you.
