"The Dragon Nightmare Flute was actually a gift Li Taibai gave this old man back then. At the time, this old man had no idea it was the Heavenly Demon Sect's Dragon Nightmare Flute. I only knew that this flute had an extraordinary provenance, and since it was a gift from a friend, I naturally took good care of it. Only later did I happen to learn its origins from some ancient texts. As for how this flute ended up in Li Taibai's hands, I am not quite sure. In my view, after the Heavenly Demon Sect broke apart, the Dragon Nightmare Flute probably drifted into the Jianghu as well. It was likely collected by the Tang Dynasty's imperial family in the end, which was how Li Taibai obtained it," Old Sun said.
After saying this, Old Sun took a book from his sleeve and handed it to Huang Xiao.
"This is...?" Huang Xiao's expression changed in surprise when he saw the title on the book.
"This is the Medicine King Scripture. This old man's Everlasting Spring Youth-Restoring Art was developed through insights gained from it. I am giving it to you now. Perhaps you may gain something from it as well. The final section contains some of this old man's insights, the experience I gained from regaining my youth so many times. Read it carefully. It should help," Old Sun said. "All right, you may go. As for Ling Tianya, just do your best. You cannot force everything."
"Thank you, Senior. I will not fail the task you have entrusted to me. I shall take my leave!" Huang Xiao hurriedly said with respect. He knew that since Old Sun was giving him the Medicine King Scripture, he had clearly made up his mind, so Huang Xiao did not decline.
