Some people drew once, some people drew ten consecutive times, but there was no difference. Han Xiao only controlled the overall cost of the boxes and did not bother when selling them off. It all depended on the players' luck. There was no manipulation behind the scenes—he wanted the players to feel the warmth of being home.
If there was a guaranteed prize every ten consecutive draws, it indeed would attract more people to make consecutive draws, but he was using the limited selling mode. There were only so many boxes every time he sold them, so they would definitely be sold out. Not only would guaranteeing a prize every ten consecutive draws not give him a higher profit, but it would also increase his costs.
If there was a guaranteed prize every ten consecutive draws in combination with the limited purchases, there might be some rich guilds that would bulk purchase, suppressing the normal players with their resources, and that would not be good.
