Ordinary True Immortals would be defeated in less than three rounds while fighting against the Immortal Flying Spirit.
It was also one of the reasons that even True Immortals who had a shallow relationship with the Immortal Flying Spirit would have to attend his birthday banquet, which was held once every 1,000 years.
Since the Immortal Flying Spirit belonged to the immortal race and had extraordinary battle prowess, only a few True Immortals dared to reject him.
Moreover, the True Immortals felt it was just a banquet. It wasn't something troublesome. After all, everyone was slightly fawning over the powerful. Moreover, they could take the opportunity to communicate with other True Immortals. Even if they couldn't improve their cultivation base, they could exchange information.
