"What's wrong?" Yun Shangyuan asked anxiously.
"It hurts, it's so unbearable..." Feng Yueya's brows furrowed even deeper.
She felt a force within her body, crashing from left to right, barely failing to burst through her meridians each time.
Yun Shangyuan immediately realized.
"Yue Yaya, you have to hold on. Taixu Zi said this potion can not only expel the toxins in your body but is also the second test he's given you. If you withstand this, you will have passed the second trial."
"Really?" Feng Yueya asked uncertainly.
Yun Shangyuan nodded affirmatively. "Really."
All of a sudden, the force within her became even more violent!
"Ah—" Feng Yueya cried out in pain, almost biting her own tongue off.
Without thinking, Yun Shangyuan reached his fingers into her mouth so she could bite on them, preventing her from biting her own tongue.
The pain was so severe, Feng Yueya was sweating profusely, her complexion deathly pale.
