Wu Jian was at the peak of the Deva Realm, and Loong Chen said that Hou Jingshu was stronger than him, which meant she must have become a Seeker Realm cultivator at the very least. That would be impressive.
Wu Meiying was also at the Seeker Realm. She had only reached that realm recently because she had been suppressing her cultivation to better increase her power before breaking through. He had been there when she reached it. The awe-inspiring sight of her entire body undergoing a strange metamorphosis as though she were de-aging had been quite the sight. She said it was the result of her cultivation method. With each new realm she reached, her body would become younger, though she could change her physical age to match her mental age.
Not that it meant much to them right now. He and Wu Meiying were both still 17 years-old. They were quite young by cultivation standards. The fact that they had reached such heights at their age was seen as a symbol of their strength and talent.
