If the blood inside the pool, despite its diluted state, was purer than what Alex had, then the only reason he could come up with was that this could only belong to the Black Tortoise progenitor. Only the progenitor could have this specific combination of bloodline elements, assuming he hadn't been mistaken.
There was a chance that Alex was entirely wrong about this all, but the chance was low. Even if he hoped for it to be low, he knew very well that the chances of the Ancestral Bloodline Pool having this specific type of bloodline elements were for a certain reason.
It was very much possible that in the olden days, this pool was crafted directly with the progenitor's bloodline as the main example for Black Tortoise blood, which led to the pool being of this specific type.
'If I'm not wrong, then I should take into account all of this,' Alex thought. 'It will be better if I absorb the purest Black Tortoise bloodline I can in order to evolve my Spirit roots.'
