See a translation

It's about paid contents in the webtoon "Pie Game." This is spoiler about this webtoon..
In this webtoon, seven people earn time from the organizers, and after the game is over (1. The time of the electronic display is 00:00. Or 2. Even one person dies.) you can earn as much money as you earn time in this secret room. The more fun it is for spectators watching this secret room through CCTV, the longer the time increases.
Participants bought time through cruel shows to invisible spectators, and the main character, who was one of the victims of the show, neutralizes all participants after a hard time and waits for time to run out.
But they didn't wait until 00:00:00,
Add time as if pushing them to kill.
A situation where there is no option other than murder.
The protagonist comes up with a way to get the organizers out of the game at all. That's shooting CCTV so they can't see the situation at all.
Through this trick, the protagonist was able to escape without murder.
At that time, the organizers send a message to the main character through the electronic display :
'you invite us.'
What does this mean?
