There are several ways for a spirit treasure to acknowledge its master.
One is like the Human Emperor Sword, consenting to lend a portion of its power to Gu Yang, but neither exerting effort nor force. When it's displeased, it completely ignores him.
When it's delighted, it can exert divine power, helping him eliminate powerful enemies.
A powerful entity like a Celestial Being, can be eliminated with one strike.
This situation can't even be considered as acknowledging a master.
Because the Human Emperor Sword can abandon him at any time.
In this relationship, the Human Emperor Sword is the dominant party.
The second type is like the Giant Spirit Hammer, having a certain relationship, its primordial spirit has reluctantly acknowledged him, it just dislikes his weak power. In the absence of a better choice, it temporarily recognizes him as its master.
This relationship is relatively equal.
