Having been able to finish just the First Form of the Tyrant Bull Totem was already a good accomplishment for Lin Mu.
After all, from what he knew, even making half of the First Form of the Tyrant Bull Totem was decent, and the minimum for one to practice the Tyrant Bull Marrow Secrets. And yet, Lin Mu had gone a step further and fully completed the first form.
The Tyrant Bull Marrow Secrets needed for one to make the Tyrant Bull Totem and there were several forms of it.
The first was the Hornless Bull.
The second was the Horned Bull.
The Third was the Legless Bull.
The Fourth was the Two Legged Bull.
The Fifth was the Four Legged Bull.
The Sixth was the Six Legged Bull.
And finally, the seventh was the Tyrant Bull!
Each of the stages conformed and matched with the Seven immortal Tribulation stages. And upon reaching each stage, the practitioner would be able to increase their strength accordingly.
