Understanding Gathered Resources

Unless you have all Gold Korean Sub-Cities, the 41 million number seems like a glitch. On my server (436), it doesn't display like that, and it certainly doesn't go that high. Maybe you're on a newer server where things are different?

I believe the 874,000 number is the amount of resources your troops have collected so far.

To collect more resources in 1 trip, you can:

1. Send more troops

2. Send higher level troops

3. Increase their troop load (through research and/or skill books)

If that still doesn't get it all, then you'll need to make multiple trips.
