Exactly because of this, they didn't carry their entire wealth on them at all times like Dong Tianyu did.
Therefore, during the salvaging operations, most of their propertied remained with the salvage team; even if the price of a Dark Green Trick Nucleus was high outside, how much higher could the price of a single nucleus be? It certainly couldn't compare with the wealth they had accumulated over the years.
Since the majority of their wealth was tied up in the salvage team when they went out, both emotionally and rationally, they would not take this opportunity to leave during diving operations.
It was for this reason that the secret of the Dark Green Trick Nuclei was able to be concealed for so long.
As the saying goes, compared to the Dark Green Trick Nuclei bought low priced from the members, when faced with the need to buy Black Devil Cores from the outside at a high price, those who originally wanted to hold out ultimately could only reluctantly give up.
