Extracting Gu

The blood vessels inside Senior Patriarch Yu's skinny body protruded slightly, and in some places, it bulged out as if there was a small bug wriggling inside. The hairs on his skin stood up as he watched. 

Not to mention, even Patriarch Yu and Elder Yang's expressions also changed when they saw this. Patriarch Yu didn't feel too badly as he knew that his father had been drugged beforehand. However, Elder Yu didn't know what was going on, the image of what he saw in front of him changed his expression immediately. 

"It's actually Gu…" Elder Yang murmured, his eyes were full of disbelief as he never thought that Senior Patriarch You would have fallen into a coma because of Gu. 

For a moment, he looked at the woman in azure clothes who had sealed Senior Patriarch Yu's tendons with silver needles with a complicated expression. He didn't understand how such an unremarkable woman could tell that he was infected by Gu?
