Global Travel: Start with a Broken Van

Human beings from all over the world are collectively crossing the desert, starting with a broken van. My van has a built-in complaint system: "The fuel tank is bottomed out, I suggest the host drink northwest wind." The school belle next door cried for a ride, so I rolled down the window: "Sorry, we only carry five people. I'm afraid we'll fall apart if you are one more." Opening blind boxes in the desert revealed strange supplies: expired Laoganma, dancing cactus. The chat group went crazy: "Who has gasoline? I'll trade it with my wife!" I silently made the deal: "One liter of water for two liters of oil, no kidding." While others are still worrying about flat tires, my broken car has been upgraded into a mobile fortress. The school belle kicked out her virgin boyfriend and ran to me: "Your car may be broken, but it's ruthless enough." A sandstorm strikes, and the fortress deploys an energy shield. The system suddenly prompted: "The ultimate mission is unlocked - the truth about the van crossing is hidden at the end of the desert."
