The issue of three connected bodies that were also separate was a unique one to tackle, and one must also bring into account the Primordial Ruination Clone and how it could always display more power than Noah's main body.
The description of the Primordial Ruination Clone that was one of the features of his Cosmic Treasure was inscribed in his stat panel as such: [...As a creature made from the very essence of a Cosmic Dao, it has a +200,000% Increase in the speed of progression through the Realms of Power, +200,000% Increase in the Comprehension and Assimilation of all Daos, can display 400% of the strength of the Master of Ruination, along with its power increased by 2000% when in the Ruination Sea…]
The key within these words was that it could display 400% of the strength of the Master of Ruination. It meant that whichever of Noah's bodies was the strongest…this was the power that the Primordial Ruination Close could display 400% of!
