Grandmaster Zi Cheng frowned slightly. In the past, there had also been visitors from the Ancient Alchemy Tower, claiming they wanted to improve the Eastern Celestial Realm's skill in alchemy, but in truth, it was just an attempt to seize power, and turn Alchemy City into their private possession.

However, he immediately broke into a smile. Others might not be aware, but he was very clear that his disciple was already a Ninth Refinement Supreme Grandmaster. Aside from Five-Star Grandmasters, who else could suppress Ling Han?
An attempt to seize power in cultivation had to be based on true battle prowess, while trying to seize power over alchemy would be based on skill in alchemy.
Ling Han was already invincible, so whom could he fear?
With this in mind, he did not show any temper. Instead, he revealed a smile, appearing very calm and steady.
