章 327: Refining the Pill of Heavenly Pulse

Shen Xing pointed at the Immortal Crane Furnace, which turned from a bright gold color to a deep grey color, and asked with a face of doubt, "This is your pill furnace?".

Following this, Shen Xing’s body trembled a little and some blood dripped down the side of his lips.

"Ah? Are you alright?" asked Chu Yu, a little taken aback, as he remembered that the mysterious lines and patterns on the Immortal Crane Furnace could not be looked upon lightly.

Shen Xing’s eyes were like a deep dark abyss and it took awhile before he could recover.

"The lines and patterns on this furnace.. They’re so strange!" remarked Shen Xing, surprised by what had happened.

Chu Yu was surprised as well, before this, the Worm King was the only one who had a similar reaction.

He never imagined that even a real saint could not look at it.

Chu Yu on the other hand, could look at it without incurring any violent reaction.

Maybe it was just because of his lower level of cultivation…
