Chapter 306: Development Success! (3)

The nerve acid separated from the instrument was a crystal clear liquid that was as pure as water.

He was stunned.

This… succeeded?!

But how could that be?! How could a high school student successfully develop nerve acid?!

Deng He gulped and felt that he must have seen wrongly.

He closed his eyes and opened them again. He saw that Xue Xi had already taken a step forward and transferred the purified nerve acid into the special test tube.

A few hundred thousands worth of materials were used to make such a small tube.

With this medicine, not to mention the cost of research and development, just the manufacturing cost was already so expensive. Hence, a mental illness could not be cured by an ordinary family!

Xue Xi sighed silently and placed the substance aside. She heaved a sigh of relief and stretched.

When she turned around, she saw Deng He looking at her as though he had seen a ghost.
