Nuwa said,"there's no definite connection between the chaos of the Three Realms and the chaos of the divine beasts." However, when you first cultivated the chaos sword embryo, you used blood as the 'nourishment'! Thus, the blood of a chaos Godbeast was connected to the chaos sword embryo!
Chen Xiaobei: Back on Earth, when I killed someone with the chaos sword embryo for the first time, I decided to use the enemy's blood to nourish my sword! After that, I upgraded the chaos Blood Sword and even gave birth to the bloodthirsty ability!
[ Nuwa: actually, you should have guessed it long ago! ] The opportunity to upgrade the chaos Blood Sword must be related to blood! And the blood of chaos is your best choice!
Chen Xiaobei: However, it was still the same problem! With my current abilities, without master, even if I get the chaos blood, I don't know how to upgrade the chaos Blood Sword!
