Chapter 425 Is everything really ready?

The art of blood refining is an extremely rare evil art. The nine realms of the world are so vast, but there are very few people who understand this evil art. According to Jin Zhuo, there are no more than ten people in the world who can use the blood refining technique. Without exception, these people are masters of the "gold" attribute, and half of them are in the Yuyi Sect.
