45 Raymond Imparts Knowledge to 20 Professors and Scholars!

Hansen was right.

After Raymond and the others returned to the lounge, someone came to inform them that they could not leave the Pentagon in the near future.

The first reason was for their safety.

When the news that the purple infrared insulation technology had been broken out spread, not only the United States was shocked, but other countries were also shocked!

Once this technology was broken through, it basically meant that a real stealth plane had become a possibility!

Apart from that, this technology could also be greatly developed in other industries!

No matter which country it was, it could not be ignored!

The spies they sent out might have already appeared near the Pentagon by now!

If Raymond and the others still went out, they might be held hostage at worst, or even killed at worst!

This kind of thing had happened more than once before. The Pentagon was very experienced!
