Hundreds of meters beneath the earth, the great black yak was grinding his teeth in pain as he extracted yet another crystalline object from his buttocks. He was so furious that he wanted to curse out loud.
He had extracted a total of four such crystals up till now.
"Damn, this is infuriating!" He was indeed incensed to the point of steaming from his nostrils. He had come quite close to being killed by the silver walnuts, leaving him riddled with painful wounds and was finally forced to hide underground.
Meanwhile, the brilliant red crystals were given to the Yellow Ox to study. Surrounded by faint red mists, the gems shone as if they were the highest grade of cut diamonds placed under the sun.
After seeing the state the black yak was in, Chu Feng could not hold back his laughter.
"This is mutant soil. However, after being nourished with the spiritual blood of so many experts, it contains an astonishing amount of vital energy," Yellow Ox muttered.
