Yin Yang Heavenly Eye had a total of five stages. It also meant that a person who possesses the Yin Yang Heavenly Eyes can awaken some kind of incredible ability a total of five times.
To cultivate every stage of the Yin Yang Heavenly Eyes, one has to first cultivate a very special cultivation technique. This technique has a total of five stages that can make a person of Ji Clan go through five awakenings of Yin Yang Heavenly Eyes and utilize the power of these eyes to increase their own strength.
What Ye Xiao had given Ji Yanran was an incomplete cultivation technique that can help her awaken two stages of her Yin Yang Heavenly Eyes. It is because, at that time, he only had those two stages of cultivation technique in his mind that he recovered from the memories of three Ancient Gods.
As for the rest of the three stages, he had yet to recover them because they were locked along with one-third of memories of three Ancient gods.
