The building where the guests were accommodated was fully equipped with various facilities, and except for not being allowed to go out at will, everything else was quite satisfactory. After all, it was only for a few days. If it were longer, the guests would not tolerate it.
There was an exhibition hall inside the building, and the project team had arranged for people to explain there, giving everyone a rough idea of the Meteorological Weapons developed by the Butterfly Project team, so they could understand what significant achievements had been made over the years with such massive funding and the gathering of global talents.
Feng Yi also went to listen. In that place, communication and photography equipment were not allowed, and documents from inside could not be taken out.
In general, the exhibition hall only provided a rough and simple introduction; more detailed explanations would be given after the live demonstration.
Nothing was as convincing as actual combat.
