Later tonight, monsters attack and the brother get poisoned.
Since it just got past midnight, MC bet on the time when the game reset his once a day thing and used miracle to summon a traveling medicine peddler + also inform the sister about it.
The peddler's POV is that his family have always been traveling peddler type, and just then he saw a pillar of light and felt the call from it, he chose to go and here he is.
After treating the brother, he also points out there's an abandoned mine nearby they can use as shelter (it's like less than 30 min walk from where the current location is)
