These prescriptions range from low-level to high-level, with a variety of functions, and they are all kinds of strange, and the annotations are obviously the tone of the Old Demon Emperor, but with Xiao Yan's current level of alchemy and his experience in the Doudi Continent, it is naturally impossible to judge their merits based on the annotations alone, but since they are collected by the Old Demon Emperor all his life, they must not be bad.

Just as Xiao Yan was browsing these prescriptions, a "huh" sound flashed in Xiao Yan's mind, and the surrounding space shook immediately.

A ray of light floated out from Xiao Yan's ring, and Zhan Lao's figure slowly condensed in the air. Zhan Lao's eyes shone with golden light, and he reached out and grabbed the prescription in Xiao Yan's hand, and quickly flipped through it, unable to suppress his excitement.

"Old Zhan, what's wrong with you?" Xiao Yan looked at the excited Zhan Lao and wondered.

Zhan Lao usually doesn't leave the tower if he doesn't have important things, but now he suddenly appeared, and he didn't have his usual calmness at all, Xiao Yan was naturally very surprised.

Zhan Lao didn't seem to hear Xiao Yan's words at all, his eyes never left the prescription in his hand, and his slightly trembling hand flipped through them one by one.

"What a recipe, what a recipe! It's worthy of the Demon Emperor's collection, it's all a good recipe-" Zhan Lao couldn't help but muttered to himself as he flipped through it.

Suddenly, Zhan Lao stopped reading, his eyes suddenly condensed, and he stared at the brown paper on his face that seemed to have been baptized by countless years, and his eyes were full of light.

"There is such an elixir, there is such an elixir," Zhan Lao was stunned for a long time, and muttered alone.

"Elder Zhan, what elixir?" Xiao Yan had seen these prescriptions, but he didn't know what the advantages and disadvantages were, and now seeing Zhan Lao so out of shape, he guessed that Zhan Lao must have seen some superb prescription, and his curiosity was aroused for a while.
