Blood Strength Gu

Blood Strenength Gu is a Blood and Strength Realm Gu.

Appearance
Blood Strength Gu has the look and size of an adult's skull. In the place were the eye sockets were localised shined red blood lights. There also some marks of blood and images of beasts fighting. In short it was like the Blood Skull Gu.

Ability
Blood Strength Gu had the ability of collecting the blood of the ones more powerful than the owner. This also includes beasts and Gu Masters.

Blood Strength Gu will collect the blood of the ones with a more powerful physique, than the owner's and refine the owner's physique. When absorbing the blood the marks will light up more depending how much blood it absorbed. When reaching the limit the possesor can either drink the blood of just spill the blood over their body to refine it. The body will be more refined if one used the blood of very powerful individuals.

The owner's body could be refined to the same extent with a lower volume of blood if the blood of the target was strong enough.

If one used Menses Blood Gu in combination with this Gu than the strengthening also occurs, but the Gu Master needs to be more careful about the increase of strength.

The whole body undergoes a qualitative change depending on the blood absorbed. If the target had strength but a weak skeleton than the durability of the skeleton will increase by a poor amount. If the target actually had good bones and used a Gu for strengthenong the bones than the results are ideal even. If the user used the blood of the ones who used different bone strengthening qualities and the blood of others who used the same effect than effects are better for both choices, even using them together.

If the Gu Master didn't had its strength increased by Gu Worms than the owner's strength increases by the strength the sacrifice had, and if the said sacrifice also was a higher realm than the owner than the Primeval Essence will also nourish the body by a certain amount depending of the said realm. This also happens if the targeted Gu Master also had a low realm.

The body's refinement is literally also at the level of the bones. Because this Gu requires certain beasts or Gu Masters with strengthened bones, or at worst ones with a strong physique so that the body could be refined to add more strength than it would be possible and not die in a short amount of time.

As for those Gu Masters with a higher rank thhan the owner, than the more denser the Primeval Essence, than the more enchanted the blood is and by extension the more the body receives a bigger overall refinement.

Bad Side
Just like most of the Gu Worms that increase strength the user needs to be careful about how much they increase their strength because if they increase it to the point it exceeds their limit than they die - because of a broken skeleton, since the fleshy body is too powerful for the skeleton to bear the weught, hence a strengthened skeleton is needed. This defect can be remediated if the Gu Master uses this Gu on a a beast with powerful bones or a bone beast.

Trivia
This Gu was a must for everyone.
