Chapter 172: Chapter 161 Elevator Puzzle

On the mobile phone screen, apart from the constantly decreasing time, there was another line with a three-digit number.

It decreased uniformly from 298, to 297, at a rate of one second per second.

It was easy to see that the three digits below represented the remaining seconds of the 5-minute countdown above… but why it was necessary to display the seconds again in this way was a mystery.

Besides these two lines of numbers, the rest of the mobile phone screen was a blank, devoid of any words.

Chen Xiao furrowed his brow; this inexplicable message provided no hints nor instructions on what to do, there was no question posed or a single word, leaving him baffled with nothing but a "countdown".

"Yo-ho~~" Chen Xiao greeted his phone, to no response...

Following that, he poked at the phone's screen and then "smack", threw it onto the ground, only to realize immediately that he couldn't dismiss this interface.
