At Li Ping's kindly words,
Yun Lingsu glanced at her grandfather beside her before nodding respectfully. "Yes, Master Yan."
She immediately sat cross-legged, took an Alchemy Furnace from her Storage Bag, and set it about a foot in front of her. Then she carefully laid more than a dozen Spirit Herbs beside her.
With a glance at the Spirit Herbs Yun Lingsu had brought out, Li Ping could tell she intended to refine First-Tier Mid-Grade Qi-Gathering Pills.
With the furnace and ingredients ready, Yun Lingsu took a deep breath before activating the furnace. She breathed a stream of true fire beneath it, and the temperature inside rose rapidly.
Just then, the first cultivator who had commissioned Li Ping to refine pills entered the Alchemy Room, led by a low-ranking steward of the Treasure-Gathering Tower.
"Master Yan, Fellow Daoist Shen-oh, Fellow Daoist Yun, you're here too." The newcomer was an elderly man with white hair and beard and the ethereal bearing of an immortal. Seeing Yun Qisheng, he looked a little surprised.
Apparently, he not only knew Yun Qisheng but was on fairly friendly terms with him.
Yun Qisheng nodded with a smile. "You've come to ask Master Yan to refine pills, haven't you, Fellow Daoist Zheng?"
Reminded of his real purpose, the elderly man hurriedly produced two Storage Bags and said with a smile, "Sorry for the trouble, Master Yan. Here are the deposit and ingredients."
Li Ping nodded and accepted them. After checking that everything was in order, he took out his Alchemy Furnace and placed it a little over ten feet from Yun Lingsu, so the disturbance from his refining would not affect her.
Whoom!
As he activated the furnace, rolling waves of heat surged outward in every direction, only to be confined within three feet of it
