738 Go Look For It in the Black Market

A group of people watched Lu Chengzhou's car leave.

After nodding to Jiang Shenyuan, Elder Bai went to the black sedan parked by the roadside.

Jiang Shenyuan turned to Mu Yu Mufeng, asking, "Are there any sleeping pills that don't have side effects when taken for a prolonged period?"

Yu Mufeng froze for a moment and soon realized what the lawyer was talking about. He pursed his lips. "If such a thing existed, Gu Mang wouldn't have needed the Sleeping Jade."

Meng Jinyang suffered from chronic insomnia and had to rely on sleeping pills in order to fall asleep every night. The Sleeping Jade had helped her sleep without the pills.

Other than the one that was auctioned at Tian Que, a different one was bought at a sky-high price by Lin Shuang on Jijing Island's black market and was sent to the lab for research. Unfortunately, there was not much progress despite the experiment having gone on for almost a year.
