Actually,
Han Yi attended the Immortal Convention of Ten Thousand Spirits for another reason; he wanted to experience the grand event of the Ten Thousand Spirits Sect and discover what made it unique.
The phrase "broad knowledge and wide perceptions" is equally applicable in the Cultivation World.
At the Immortal Convention, there were Ancestors preaching and Immortal Venerates discussing the Tao, which was greatly beneficial to him.
Although Nine Sparrows Hall had risen, its foundation was not strong. Even eight thousand years ago, when the nine veins coexisted, it was only a mid-tier Immortal Palace. Apart from a few Immortal Monarchs who noticed Jin Ming's emergence, it caught the attention of the Fierce Sun Immortal Sovereign.
However, the Fierce Sun Immortal Sovereign's expression was indifferent, showing no emotion, nor did he purposely probe Jin Ming. The attitude he exhibited towards the appearance of the Nine Sparrows Hall Master was almost of disinterest.
