Hehe, this is the trick of the merchants. There are two reasons why your ring arm is small: to change the ring (especially to get bigger), you need to add gold. They certainly didn't feed you. Two: If it is only changed a little, the retaining wall is much smaller, which means that the repairman stole a little gold. Most jewellery in Liu Fu are franchisees. These small bosses won't support you. Stealing some gold from aqua regia is hard to detect.
