Everyone in the cultivation world knew—
Beast Tamers with the cultivation of a Scholar could use spiritual power to fight on land. Beast Tamers with the cultivation of a Master could use spiritual power to fight in the sky. Beast Tamers with the cultivation of a Supreme Master could fuse with their beast form and freely control their beast form to change their battle form.
On the other hand, Grand Master Beast Tamers could completely fuse with their beast forms and achieve the power of one plus one greater than two in battle.
After a Beast Tamer broke through to the Prime Master Realm, their beast form would be given life and become a demon beast that cultivated on its own.
After Beast Tamers reached the Divine Master Realm, their beast form could even have a human body. They could completely escape the restrictions of the demon beast bloodline and have a brand new life.
However, this only existed in legends.
