I Picked up Iron Man's USB Flash Drive at the Beginning.

"Hello, I am Iron Man Tony Stark. I and the rest of the Avengers had an accident when we traveled through time and space and were trapped in a rift in time and space. I contacted you in this way and asked you to help me build a quantum machine to pull us out of the rift. After that, I promise to give you 10 billion US dollars and the latest version of the Iron Suit." "... Crazy, it's 2021, and there are still such tricks, but it's a bit novel to put it in a USB flash drive. This USB flash drive looks good, format it and keep it for your own use." However, just after Zhou Li clicked OK to clear the USB flash drive, his computer screen suddenly went black.
