What drew Ling Han over was a herbal aroma.
As the Alchemy Emperor, he might not be considered an elite of alchemy at this moment, but was definitely at the level of a prodigy. He could detect the slightest smell, and be able to track it down.
This was a Celestial pill!
At first, he had only come here to have some food and drinks. Ling Han himself did not have much interest, but there was actually someone concocting a pill in this place, and this garnered his curiosity, and he wanted to meet the person who was concocting a pill.
Now that he had advanced into the Severing Mundane Tier, he was qualified to refine Celestial pills.
The Empress was proud, and thought that all beings in this world should become subjects for herself and Ling Han—even if they did not offer their allegiance now, they would do so in future. Thus, she naturally was completely unconcerned that Ling Han would be barging around carelessly like this.
