There was no further explanation regarding the increase in grade, but there was a detailed explanation of the General Star. Niu Jinxing’s corpse had a Heavenly Spirit General Star, while the other three had Earthly Fiend General Stars.
Three Earthly Spirit Stars could be fused into a Heavenly Spirit Star, so this Innate Talent Blood Crystal could be said to contain two Heavenly Spirit Stars within it. If it was given to someone without a General Star, that person would be able to obtain a Heavenly Spirit Star, but if it was given to someone who already had a Heavenly Spirit Star, it was possible for that person to awaken one of the 13 General Stars.
This was because three Heavenly Spirit Stars could be fused into a Great General Star. Now, Zhao Fu understood why the Innate Talent Blood Crystal could be further fused.
