Dungeon Survival: Ten Coupons at the Start

Ye Tian, ​​who was accidentally hit by a truck, found himself in a dungeon. This dungeon is no different from a regular RPG. But unfortunately, any player only has one life. If you want to go back, you have to clear the level with one life. Fortunately, Ye Tian activated the system. "A coupon for a discount of 150 gold coins when you spend 149 gold coins." "Eight general-purpose 20% off coupons." "An offset coupon can offset any consumption with a total amount of 49." Relying on these magical coupons, Ye Tian went crazy to get things from NPCs. I want a long sword of 199 gold coins because of Ye Tian's coupon. The npc has to pay him a hundred gold coins. This novel and its characters are purely fictitious.
