Celestial Foothill Gardens.
Tang Hao was sitting cross-legged on the floor in one of the rooms in the mansion. Heaps of medicinal herbs were placed around him.
He picked up a stalk of herbs and held it in his palm.
His palm was soon enveloped in a warm, pale glow like moonlight.
After holding the herb in his palm for one or two minutes, he placed the herb into a mortar with a few other herbs and smashed them with a pestle.
Soon, a small bowl of medicinal liquid was produced. He poured the liquid into a bottle and diluted it with tea. The result was an aphrodisiac potion.
He placed the bottle into its packaging and set it aside.
After a short rest, he started production on the next bottle.
Crack! Boom!
He heard a thunderclap from outside the window. Lightning flashed across the night sky, briefly illuminating the surroundings.
Tang Hao lifted his head to see that there was a thunderstorm outside.
