According to the secret teachings passed on by the Falling Star Sovereign, Lin Zhen began to practice the Beast Commanding Decision.
But it didn't take him long, just a mere half a year.
Six months was a significant amount of time for Lin Zhen, because a half year for him was equivalent to fifty thousand years for others!
Fifty thousand years to practice a single secret manual indicated its complexity.
But half a year later, Lin Zhen thoroughly understood the manual, demonstrating his mastery of it.
Now, the only thing that Lin Zhen lacked was practice.
In order to acquire the necessary experience, Lin Zhen had to personally go to Beast King Prison. There, he could use the Nine Palaces Purple Gold Bell in conjunction with the Beast Commanding Decision to tame the fierce beasts.
But Lin Zhen didn't have time to go to Beast King Prison. His own cultivation was not yet complete.
