Fast forward to three years later.
It was not a particularly long time but it wasn't short, either. Many things were happening at the Heaven Reverse Universe, though not major ones.
Lu Li cultivated for three years, and he only stopped once when Jiang Qiling successfully reached the Semi-God Realm.
She was talented. When she was younger, she loathed cultivation. Once she committed herself, she achieved fast progress.
Emperor of Heaven Reverse had passed onto Jiang Qiling his legacy, something similar to the Map of Fundamental Principle. It was not hard for her to reach the Semi-God Realm warriors following this path.
