Inside the Cangjiang Water Mansion:
"Chirp chirp..."
A demon fish with a swollen head and bulging eyes let out strange cries, struggling violently.
It hadn't struggled for long before its eyes suddenly burst open, its entire body convulsed, and it directly turned into a pool of pus, dead and gone.
"..."
Zhang Yao's expression was somber as he slowly withdrew his magical power, feeling extremely frustrated.
For a full ten years of experiments, he had harmed countless demon races in the Cangjiang Water Vein, yet he had never succeeded.
Thousands of attempts resulted in failure time after time. To this day, the process to enhance the demon race bloodline was still stuck at the final step—
No matter how smoothly the Primordial Energy fused, once the bloodline catalysis began, a mutation was inevitable.
"Alas..."
Zhang Yao sighed deeply, a hint of fatigue showing on his face.
"To this day, I haven't found a way to reverse the flesh and blood mutation."
