The thing about转运珠 that has been热烈ly discussed, let's see what it is.
(Note: "热火朝天" is a Chinese idiom that means something is very popular or intensely discussed. It can be translated as "heatedly" or "intensely" in English.)
A more natural translation might be:
"The topic of转运珠 that everyone's talking about so enthusiastically—let’s see what it actually is."
