In the blink of an eye, afternoon arrived, and Xu Changqing headed out once more.
Sure enough, the door was open this time, and Zhang Su was home.
The moment Zhang Su saw Xu Changqing, he was delighted. Smiling, he said, "The alchemist I know happened to finish refining a new batch of pills today. We'll definitely get priority when buying them."
Xu Changqing nodded slightly. "I'll leave everything to Senior Brother's arrangements."
Zhang Su did not waste any time. After summoning his mode of transport, the Camouflaged Wooden Butterfly, he waved. "Get on. We're heading to the Alchemy Pavilion now."
Xu Changqing put away the Big-Leaf Grass, then leaped up and landed steadily on the butterfly's back. He had expected it to be soft, yet it was unexpectedly tough and resilient.
Zhang Su's thoughts stirred, and with a command, the wooden butterfly beneath his feet began flapping its wings. Fierce gusts rose around them, sending weeds flying chaotically and scattering broken stones in every direction.

At this moment, Zhang Su said, "The Alchemy Pavilion lies south of our Spirit Fields. There's an exceptionally rare patch of Earthfire there. They say it can improve pill quality and remove even more impurities."
Xu Changqing smiled when he heard that. "This is my first time going there."
