The moon and the sun alternated shifts as time passed. The storm caused by the Great Empress mystic realm had been made known throughout the Tian Yuan world. When people heard of the "six realms" ranking of geniuses by the ancient Great Empress, they knew that the children of Heaven from the various large factions were just broken halberds buried in the sand when placed in the Great Empress mystic realm. And under this situation, Yi Yun and Lin Xintong, who came from the Lin family, managed to obtain the Great Empress' inheritance.The Great Empress' inheritance was no trifling matter. All the large factions coveted it, but they were helpless about it. After the Great Empress' trials ended, they could not even get through the door.As for the Lin family, they had long since distanced themselves from Yi Yun and Lin Xintong. It would not be wise for anyone to attack the Lin family.In this way, the seasons changed, and slowly, there were a lot fewer family clans who were still coveting the Great Empress mystic realm. Only the Shentu family clan, who were still brooding about it, would constantly send their family clan's legendary figures to the Untraversable Sea for patrols, hoping that they would find traces of Yi Yun and Lin Xintong.However, Yi Yun and Lin Xintong had seemed to vanished. Many people believed that they would remain in reclusion in the Great Empress mystic realm for a few decades. It was unknown how powerful they would be when they finally came out.Year after year, five years had now passed since the Great Empress mystic realm's trials ended.To warriors, five years was not a long period of time, but it was enough to make them slowly forget some things. For example, the gigantic Eye of Destruction that had suddenly appeared in the eternal whirlpool, which made one's soul feel like collapsing just by facing it.As time passed, the fear many large factions in the Tian Yuan world had for the eye slowly diminished.After all, the God Burial Abyss was synonymous with mystery. The strange phenomena that appeared from it was not something unacceptable. From the looks of it, the eye did not seem likely to exit the eternal whirlpool, so it was unlikely for it to affect their foundations in the Tian Yuan world.However, for Yi Yun, five years was a long period of time.He was, after all, still young. His life had just begun. For a young elite, five years was enough to make his strength progress greatly.This year, Yi Yun turned21 years old. He had cultivated diligently for five years, but his progress in his cultivation level was not fast.His cultivation level was only at the peak of the middle-stages of the Dao Seed realm. He was just one step short of entering the late stages of the Dao Seed realm.The reason why his cultivation level progressed slowly was not because Yi Yun wanted to strengthen or consolidate his foundation.Yi Yun believed that even if he had reached the peak of the Dao Seed at the age of 21, he would still have a perfect foundation.The reason why Yi Yun's cultivation level was slow to progress was because he was using most of the time to study the "Great Empress Heart Sutra", as well as the sword Dao of the Azure Yang Lord.The "Great Empress Heart Sutra" was, after all, a supreme technique that was derived from the "Yang God Manual" and the "Nine Nether Sacred Manual". To reach the large success stage of the "Great Empress Heart Sutra", they needed complementary Yin-Yang to cultivate Nine Yang Spiritual Energy that had life. Yi Yun and Lin Xintong used their extremely compatible bodies to master the first stage of the "Great Empress Heart Sutra" quickly, but it was no longer that easy to cultivate the second stage of the "Great Empress Heart Sutra".To give life to their Yuan Qi, they needed to transform the pure Yang energy into Nine Yang Spiritual Energy, while the pure Yin energy had to transform into Jade Marrow Spiritual Energy. Their bodies not only needed great affinity with energy, they also had to have the insight and opportunities to do so.Yi Yun and Lin Xintong were not lacking in terms of perceptivity. However, opportunities were not easily chanced upon.This needed their energy to obtain a trace of spiritual consciousness that could not be obtained from searching for it. After Yi Yun and Lin Xintong gained Nine Yang Spiritual Energy and Jade Marrow Spiritual Energy, they could begin cultivating the third stage of the "Great Empress Heart Sutra". As for the third stage of the "Great Empress Heart Sutra", it was even harder to master. It even needed Yi Yun and Lin Xintong to really become as one.Their bodies had a natural attraction to each other. The more they cultivated, the more spiritual their Yuan Qibecame. Then, when they finally made the final step, the benefits they obtained would be greater.At that moment, Yi Yun was suspended above the lava pool, one of his legs folded while the other was tip-toeing on the red lotus which was floating on the lava pool's surface. He was respirating pure Yang energy.As for Lin Xintong, she was sitting cross-legged on the frost ice bed. She was working in concert with Yi Yun from far. Yin and Yang energies were circulating between their bodies.Yi Yun raised his arms gently as two blobs of Yuan Qi, one gold and one blue began to transform around his body. This was pure Yin and pure Yang energy. Lone Yin did not lead to birth and solitary Yang did not allow growth. In the past five years, Yi Yun had already started cultivating both Yin and Yang.The two blobs of Yuan Qi transformed. The pure Yang energy was clearly more powerful than the pure Yin energy. It sometimes transformed into a Golden Crow, at other times, a flood dragon. It could even become a Black Turtle, a flying dragon-snake, a fierce tiger, an eagle...The creatures that appeared were a depiction of life. The manifestation of Yuan Qi was the first step to forming life.In these five years, the Radiant Sun Qi that Yi Yun cultivated from the "Tai Ah Sacred Technique" had been completely absorbed and transformed by the "Great Empress Heart Sutra"'s pure Yang energy. It became the basis for nurturing Nine Yang Spiritual Energy...However, Yi Yun still failed to make that final step.Up to now, Yi Yun had attempted it countless number of times.Usually when such a bottleneck was encountered, going out on a training trip was a good choice.Warriors, especially young elites, could not be content with remained safe. If they continuously trained inreclusion they would encounter a bottleneck over time.When that happened, a training trip or venturing into a mystic realm would provide them with opportunities that could let them gain insight or have a break through in one fell swoop.Now, this phenomenon has begun to appear after they had remained in reclusion for five years.As for Yi Yun and Lin Xintong, they could not leave the Great Empress mystic realm this early. They had to master, at least, the second stage of the "Great Empress Heart Sutra".Without being able to travel outside, Yi Yun could only explore inside the God Advent Tower.With the Azure Yang Token, Yi Yun could open the God Advent Tower's second level's vast wilderness world, or the fourth level's extreme frost icy plains.He and Lin Xintong had explored these two worlds several times, but they did not gain much from it.Today, they came to the third level of the God Advent Tower. The third level of the God Advent Tower was a grand hall filled with cultivation technique manuals.Yi Yun and Lin Xintong had previously chosen cultivation techniques in this grand hall so they had also seen this place before.However, they both stopped in their footsteps when they arrived here today."Oh? This is..."In front of them, there were portraits hung on the walls of the grand hall.The two portraits had been seen by Yi Yun and Lin Xintong separately.One of them was the Great Empress' portrait. The plainly dressed woman in the portrait only revealed her back. Her long hair was disheveled. Her clothes fluttered in the wind as she walked on thin air with the tip of her barefooted toes.And below her feet was a vast extreme frost icy plains. With every step the simply-dressed woman made, an ice lotus would bloom under her foot.As for the other portrait, it was that of the Azure Yang Lord.The Azure Yang Lord was sitting on the ground, with his back leaning against a tree. One of his hands was holding a wine gourd. He was gulping down wine. Beside him, his sword was stabbed into the ground diagonally. The blade of the sword was even stained with blood.The two portraits, with one beautiful and the other unruly. It gave off a strange feeling when they were placed together.Upon seeing these two portraits, Yi Yun and Lin Xintong suddenly thought of something. At that moment, they had a different feeling...
