I found a tool-buying hut in the city of Mongle on the left in the picture below, in which is an orthopedic doctor. Sneak directly face to face, don't touch the three boxes piled at the door again (1 the probability of theft is also 33%) (you can also pry open the safe and the iron box, but don't look at the possibility of being attacked by the osteopath) (sometimes the guards come in regardless, sometimes they chop people), go out and hide in the corner and wait for the alarm, and then go directly to the store on the side to sell artificial limbs. The three boxes are 14-66.
