A successful Dao Proclamation Descendant Self Sword could be ever-changing. After a round of testing, Chu Kuangren was pretty satisfied with it. Besides the ever-changing feature, Chu Kuangren's main focus was on the Immortal Weapon's power.
After all, strength was the most crucial when facing the real elites, as they could break all techniques.
The power of the Dao Proclamation Descendant Self Sword was impressive and comparable to a top-notched Earthen Immortal Weapon. On top of that, it also possessed two abilities that attracted Chu Kuangren.
First, the Dao Proclamation Descendant Self Sword could not only absorb the Dao Proclamation Seals for its use. It could even absorb and refine other Immortals' Dao Proclamation Seals.
Second, it could either absorb spiritual qi or continuously improve its toughness through being refined by cultivators and then make itself indestructible.
