As Grand Ivan said, it's just an intelligence dealer, not something rare.
Grand Ivan definitely has no reason to deceive Gao Yang, and besides, some things are self-evident. Once the paper window is broken, even someone unfamiliar with the circle can understand. Indeed, as Grand Ivan said, no single person could establish a global intelligence network, not even America.
The logic is simple: what's the point of establishing an intelligence network in a place nobody cares about? So, purely from a cost-effectiveness standpoint, even if Justin had the capability, he couldn't truly establish an intelligence network.
Gao Yang once thought Justin was the best intelligence dealer in the world, but that's because he hadn't seen much. Now that Justin is merely part of the intelligence network, replacing him becomes easy—Grand Ivan could introduce someone just as capable.
