The audience of the "PVP Arena" wasn't just Chu Guang, Xia Yan, and the experts from Huge Rock Military Industry; there were also many "unrelated individuals."
Apart from the observation area that was equipped with various professional detection devices, there was also a "spectator stand" set up outside the military blockade zone, open to other players and technicians learning on-site, to gain new design inspirations.
The feed had a half-minute delay and would only cut off the broadcast in rare cases, but most of the time, it was openly viewable.
Anyway, these devices would ultimately be sold to players for use; keeping them secret didn't really make much difference. It was better to just bring them out clearly for these experts to observe.
If you have good ideas, you don't have to hold back; you can talk about anything.
