Gui Yang's actions were tantamount to making a statement, demonstrating his loyalty to Jing Yan.
Knowing that Jing Yan was the true Pill God, Gui Yang pledged his unwavering devotion. He did not have much ambition in the Martial Arts but worked tirelessly on the Alchemy Dao. The main reason he entered the Despair Abyss three hundred years ago was to make progress in the Alchemy Dao.
Naturally, Jing Yan was very pleased with Gui Yang's declaration of loyalty. In the future, he certainly wouldn't have much time and energy to personally manage the Splendid Dojo, so leaving it to Gui Yang was perfect.
Jing Yan had a closer relationship with Hu Donghe, but Hu Donghe was the Pill Spirit City Lord. Surely he couldn't be expected to sit in residence at the Splendid Dojo every day?
