"Practice hard and strive to break through to the Middle Golden Core Stage before the Secret Realm opens," Li Zhirui said to Jiang Fengwu, full of confidence.
Actually, Jiang Fengwu's talents weren't bad; otherwise, she wouldn't have been able to fight her way to her current realm as a Loose Cultivator.
Unfortunately, due to her background, she had delayed quite a bit of time, so when she broke through to the Golden Core, she was already over a hundred years old and couldn't enter the Secret Realm.
The reason Li Zhirui hoped she could break through to the Middle Golden Core Stage was to speed up her cultivation, giving her more time to attempt breaking through to the Nascent Soul. He didn't wish that, centuries later, Jiang Fengwu would die before him.
