The sound quickly dissipated, and all was quiet again.
Li Chengyi frowned and glanced at the counter, where he quickly spotted a standing sign.
The sign was the size of a palm, predominantly blue, with a black and white QR code in the center, obviously for convenient payment.
"I paid by scanning the code," Li Chengyi said loudly.
With that, he took out his phone and scanned the QR code.
Beep.
The phone let out a crisp sound, but then froze, failing to jump to the online payment program of the UnionPay network.
'No internet?' Li Chengyi narrowed his eyes, feeling that something was off.
He picked up his phone and dialed a few keys, then scanned the code again.
Another beep.
The screen still stuck on the scanning interface, with a green light moving up and down continuously, but still not proceeding to the payment interface.
He thought for a moment, quickly exited the scanning function, and opened the browser.
