After examining, I registered myself without having to expose my face. Every special wristwatch has a unique identification number, and this number can't be forged by just anyone.
Once my identification number was used to verify Du You's information, they let me through.
At the same time, there were other people waiting to enter and exit. The entrance of the city was not a deserted place; on the contrary, it was very bustling.
"I've heard a lot of people like to hunt outside the city on Earth, it seems to be true."
Du You stepped onto an elevator that brought him to the top of the city wall. That's right, the main gate wouldn't open for them, they had to use the elevator for entrance and exit. This elevator, similar to a magnetic levitation transport, seemed similar to those autopilot cars.
