The saying "times have changed" fits perfectly—back then, when Frank wanted to hunt for treasure in the rainforest, he had to save money for a long time and sell off his assets. And even then, he only managed to gather five people.
But now, even though Gao Guang's bank accounts are frozen, he can still easily pull together tens of millions of US Dollars for emergencies. Using it as funding for treasure hunting is not an issue at all.
And then there's the difference in equipment. Back then, a few people rented a small plane and scoured the rainforest from the skies by visual search methods to locate treasure. But now? Now Gao Guang can rely on technology.
What he needs are manpower, money, and connections.
With connections, Gao Guang can get his hands on ground-penetrating radar.
If an airborne early warning plane could be used, that would be ideal. Unfortunately, Hank is caught in the crossfire now and can't provide military services for a price like he used to.
