Basically this chapters about the two of them wanting to know each other more, then Jaeshin decides to take Lee know out into town and they're now playing a gambling game. Lee know gets concerned because of the amount of money Jaeshin throws onto the table but, Jaeshin says it doesn't matter because he'll make sure to win Lee know a lot more money than he threw down. The old man that we see at the end of the chapter,... I'm not 100% sure but I think it's the old guy from the beginning of the story (this guy makes a bet w Jaeshin and if he (Jaeshin) loses, he has to extend his life span. Jaeshin losses and extends the guys life but, he exchanged life spans with his son and now his son is dying, that's how Jaeshin tinkered w the book and got punished for it). I'm assuming the old guy is coming for blood now. That's just my theory tho. (For those who need clarification) pt 2
