Eternal Immortal Clan

If you can become an immortal through hard work + talent + luck, you would be taking family inheritance too lightly. Immortals have heirs, which are passed down for hundreds of generations. After a hundred thousand years, they become an immortal clan. The immortal clan masters the knowledge of cultivating immortals and monopolizes the way of cultivating immortals. After tens of thousands of years of accumulation, how can it be broken by a mortal's efforts in one lifetime. Everything is destined at birth in the Xuanzhao Realm. The descendants of mortals are destined to be mortals, and the descendants of the immortal clan are destined to be immortals. This is destiny!
