Is it a loss to exchange one G&D red Gp for three black diamonds LGR?
No loss. Because the red gp value of a Jade Emperor is around 10 yuan, which is rare and harmful, and may be around 20 yuan, while a black diamond LGR can be sold for hundreds of thousands, so a Jade Emperor's red Gp is not a loss for three black diamond LGRs, and it is likely to be a gain.
