158 Testing and Exhausting Disaster

Upon hearing these words, Zhou Bai's heart jolted, and as he looked at Lin Muqing in front of him, it felt as if a chill had seeped into his heart.

For a moment, his mind was flooded with thoughts.

"What did she mean by those words?"

Zhou Bai thought for a moment and casually responded, "We don't even understand the principle behind the immortality of the Heavenly Demon, so it's impossible for us to learn it."

"It is indeed very difficult." Lin Muqing smiled, "But if there were a chance for you to become immortal like the Heavenly Demon, would you want it?"

Zhou Bai felt a surge in his heart, "Is this... testing me? Or is it that Teacher Lin..."

Suddenly, the image of Xing Jun appeared in Zhou Bai's mind.

The power of the Primordial Spirit connected with the gemstone in his brain, and then Zhou Bai glanced at his watch.

'Time can be reversed... since that's the case... I might as well test her.'
