Desert Survival in the Apocalypse

I was originally a serious person, until one day, I met an unserious blueprint. Blueprint: "This system is an orthodox sect. Wanling coins are just advertisements. Without advertisements, where would the funds come from? How can I fly you without funds!" Li Feng: "Huh?" Blueprint: "Don't worry! To outsiders, we look like sales! But in fact, we are hard-working revolutionaries! One day we will overthrow this evil Wanling Company." Li Feng: "Then after the overthrow, can I take off my advertising uniform?" Blueprint: "That won't work! The advertising fee is 1 billion Wanling coins." Li Feng: "?" But you only gave me 10 Wanling coins! Who are the capitalists? Blueprint: "Don't worry! One day, I will lead you to kill all these evil capitalists! Destroy all the Wanling Coins in the world! And this Wanling Company." Li Feng: "..." In the last days, people fall into a trap by mistake and are forced to sign contracts for sales. What should they do? Wait online. It's quite urgent.
