Because time in The Void flows much slower, thousands of years have already passed in the Primal Spirit Realm.
During these years, although the Li family has become dormant, its internal development hasn't slowed down. While no new Heavenly Immortals have emerged, many new Earth Immortals have appeared.
Cultivation of people like Jiang Fengwu and Li Mingyao has also seen significant improvement.
The reason for such excellent results is partly because Li Zhirui's transcendence provided them quite the motivation to follow his footsteps.
The second reason is the cultivation experience and insights he left behind, which have served as a catalyst.
After all, Li Zhirui and Li Zhixuan are different. The latter had no accumulation in the Heavenly Immortal Realm, so her insights were naturally not of much help to Jiang Fengwu and others.
