"We speculated that something might have happened in the city, so the bodies were transported out of the city for burial. These people pretended to be dead and crawled out from the pile of corpses."

"So I brought them back, and they said nothing when I asked them on the way."

Upon hearing this, Xia He frowned and his eyes fell on the civilians.

They were filthy and their clothes were stained with blood, and it was obvious that they had undergone inhuman torture.

Xia He squatted down and asked in a gentle tone:

"Who are you? Is there a riot in Youzhou City?"

But no matter how they asked, the two men just refused to speak, and the look in their eyes clearly showed that they had suffered inhuman torture.

Xia He frowned and sent someone to find Su Changfeng.

"Su...Master Su, why are you here!?"

One of the civilians raised his head, and there was finally some life in his eyes.

"Let me ask."

When Su Changfeng saw the two people, he instantly understood something.

Xia He nodded and left to wait outside.

After about an incense stick of time, Su Changfeng finally came out and said,

"These two people were slaves. They were originally servants of the wealthy families in Youzhou City."

"Some time ago, shortly after the spiritual grass matured, they were captured by the government for drug testing... To put it simply, these people are the lowest class of drug slaves."

After hearing this, Xia He was quite shocked and couldn't help asking, "Test the medicine? How?"

"Although Linghe can be used to refine spiritual medicine, it is highly poisonous and cannot be eaten in a short period of time."

"Someone has come up with a way to use living people to filter out the poison! It only takes five or six people to filter out the poison from one poisonous herb, which greatly shortens the refining time."

"The two great families relied on this method to transform a large amount of poisonous grass into real spiritual grass. After they were refined into pills, each pill was worth hundreds of taels of silver!"

"As for those who died along the way... the poison is hard to remove, so they can only be transported outside the city and buried. Now the area behind the mountains of Youzhou has almost become a mass grave!"

Xia He took a breath of cold air.

“Is there anyone who does this?”

"It's this Linghe again..."
