12000 should not be enough. In front of the Soul Shop 15 Soul can be refreshed automatically. After the fifteenth soul, it must be refreshed manually, and the probability will be lower. The price of the soul shop should be similar to that of the forbidden area. When the forbidden area was closed before, 18000 ingots and Ying Zheng 24000 were left outside the forbidden area. Almost five-sixths of the price can be taken down, that is, it adds up to thirty-five thousand ingots. It can be cheaper if you brush it together in the soul shop, but 12000 is impossible. If you only change one, you can try the remnant rainbow Nie Gai.
