The path of the moon returning to the blood night is a day that is rare to see in a hundred years. On that day, the blood energy brought by the blood moon path was too heavy, so only the powerful saints could create their own extended veins, and the hidden ability of the extended veins they created was thousands of times stronger than the extended veins created on ordinary days. Moreover, the Yanmai created on the day when the moon penetrates will also gain special abilities by absorbing the powerful blood moon energy. Its special abilities may only burst out under certain special circumstances - or they may be revealed inadvertently.
