Chapter 42 Xue Zheng's Shock

"Hmph, clearly you understand nothing..."

It was only after Mo Wangchen and Zhang Hao's figures disappeared that Tang Zihan let out a cold snort, a hint of disdain reappearing in her eyes.

Currently, as a first-grade Alchemist, she naturally knew much about the Alchemy Dao. Green Darkness Grass was the main ingredient for the Returning Ruins Pill, and yet Mo Wangchen had said to replace it with the most common, lowest-grade Cold Crow Leaf?

"Cold Crow Leaf..."

Tang Zihan did not notice that after hearing Mo Wangchen's words, her mentor frowned and fell into deep thought.

Moments later, a brilliant gleam flashed through Xue Zheng's eyes, as if he had realized something, and his body couldn't help but tremble slightly, "Cold Crow Leaf! I understand now!"

"M-Mentor?"

Seeing her mentor react this way suddenly, Tang Zihan couldn't help but be startled.
