The Great Empress mystic realm trial lasted for a full year before it finally came to an end.However, all of that no longer had anything to do with Yi Yun and Lin Xintong. They did not intend on exiting to begin with.At that moment, Yi Yun and Lin Xintong were standing on a white jade staircase. In front of them, there was a heavy ancient door.The door was made of some unknown cast metal. The surface was covered with elaborate patterns and engravings.The left side of the door had a carving of a Radiant Sun, and on the right, there was a Frost Moon carving.This door was the entrance to the sixth level of the God Advent Tower.It was also the last level. As for what was inside, Yi Yun had no idea."I can't open it."In front of the door, Yi Yun shook his head. Despite having the Azure Yang Token in hand, he couldn’t open the door.Standing beside him, Lin Xintong looked at the two engravings on the door carefully. She gently reached out her fingers and swiped her fingertips across the carvings.After a while, Lin Xintong said, "The surface of the door has an array embedded on it. This array is also the door's lock. Maybe it requires for us to cooperate in order to open it."Lin Xintong's words caught Yi Yun’s attention. He focused and touched the Radiant Sun on the left side of the door with his palm.The Radiant Sun engraving was quite similar to the Radiant Sun picture of the "Tai Ah Sacred Technique". Of course, the profoundness was on a much deeper level.When he sank his perception into the Radiant Sun engraving, Yi Yun slowly came into contact with the array's core. He too began to understand the principles behind it.The Radiant Sun and Frost Moon array needed to be injected with pure Yang and pure Yin energy to power it. Only then would the array activate, opening the door to the sixth level of the God Advent Tower.From the looks of it, access to the first five levels of the God Advent Tower could be obtained through tests. Only the sixth level was different. It probably required one to cultivate the "Great Empress Heart Sutra" up to a certain realm before entry was allowed… With a slight hesitation, Yi Yun tried injecting his energy into the Radiant Sun engraving.As for Lin Xintong, she took the hint and also placed her hand on the Frost Moon engraving.They placed one hand on the array, while they used the other to hold hands.Their minds were one, with Yin and Yang complementing each other.Pure Yang and pure Yin energy surged into the door. The ancient patterns were lit up one by one.Momentarily, the ancient bronzed color door began to vibrant with flowing light. The two engravings, the Radiant Sun and the Frost Moon seemed to come to life. In the world of the engravings, it seemed like shadows were cast, as if it became a real world. As the Radiant Sun appeared, plumes of cloud began to fill the sky. When the Frost Moon rose, it brought a vast star-filled sky with it… Alternating scenes of Yin and Yang appeared one after another until 70-80% of Yi Yun and Lin Xintong’s Yuan Qi was drained. Sweat began to appear on their foreheads, however, the door door remained tightly sealed. It did not look like it had any intentions of opening.Finally… when the two ran out of energy, with their Yuan Qi depleted, the splendid light figures that had surrounded them disappeared. The shiny array patterns also began to darken. The white jade staircase returned to darkness, as if nothing had happened.Yi Yun and Lin Xintong looked each other in the eye. They were helpless. Lin Xintong sighed and shook her head, "We are still far from the mark. Our strength is far from enough to open the door.""Indeed… "Yi Yun stopped the outflow of pure Yang energy and he was somewhat indignant.What was in the sixth level of the God Advent Tower? If he could really open it, he might obtain a few means to protect himself against the upcoming upheaval of the Tian Yuan world… ...While Yi Yun was looking at dejectedly the door to the sixth level of the God Advent Tower, about hundred a millions kilometers away, another similar scene was happening. There was a long staircase, and a figure was slowly moving up the staircase… It was a vast piece of land. In the middle of it, there was a large and magnificent altar. This altar was completely black and it was thousands of feet high. The altar's stone pillars were not smooth, they were completely covered in bumps of various sizes. The bigger ones looked like winding dragons, while the small ones were like the fingers of a baby.These bumps were not just for decoration, they were bones that were casted into the altar.From the countless numbers of bones, there was the aura of nomological energy. They were not ordinary bones, they were bones of powerful desolate beasts, or even bones of mighty figures from ancient times.This was an altar built from divine bones!In the middle of the altar, there was a long and straight staircase. The staircase emitted a red glow, as if it had been washed by blood.The staircase led from the peak of the altar to the bottom. It was like a red waterfall that loomed downwards.A woman's figure was slowly walking up the staircase as she headed to the top of the altar… Around the woman and the altar, there were countless numbers of desolate beast gathered on the land. They were all witnessing this scene quietly.Amongst these desolate beasts, the large ones were like mountains, while the small ones were like ants. There seemed like an infinite number of them as they reached far into the horizon. Even to the ends of one vision, one could only see a dark mass up to the fog in the distance. The figures of the desolate beasts were also hidden in the fog. There was no end to be found… None of the desolate beasts, be they powerful primordial true spirits or weak common poultry, made a single sound. They were gathered around the divine bone altar in veneration. Their expressions were that of awe, and each one of them appeared like statues.The woman was wearing a thick, dark red long robe. She held a cane that was about half an average person's height. The cane was like a sharp pick. The top was slightly rough, while the other end was thin and sharp. On the top of the cane, there were unknown Totems engraved on it.The long cape hanged down behind the woman and she was dragging it up the staircase. There were Ancient Totems engraved on the cape. The woman's black hair cascaded down like a waterfall behind her, covering the Totems… The woman had a slender physique. Her lips were bright red and in the middle of her eyebrows,there were three cinnabar dots. They seemed to add an indescribable quality to the woman’s bearing.She was like a blooming red plum in the world. Her magnificence was suffocating.When looking at her, it could not help but make people think of the poem, "The blood that stains the lands avowed, how doth it rival the crimson dot by thy brows..."This woman was not even in her twenties, and her name was… Jiang Xiaorou.She was the most important woman in Yi Yun's life. Even if Yi Yun was standing here, he might be lost in thought for a moment before he could recognize his elder sister… Compared to that simple and elegant girl in the Cloud Wilderness, the present Jiang Xiaorou seems to have been reborn.Step after step, she climbed the staircase to the altar. In the middle of the girl's eyebrows, there was an inexplicable hint of melancholy. Her steps also began to subconsciously slow down… Amongst the countless numbers of the desolate beasts, there stood people from the Desolate race. They too were also watching this scene."Rou'er, why the hesitation?"At that moment, a kind and pleasant voice rang in the girl's ears."Nothing, Mother."Jiang Xiaorou shook her head gently. The melancholy in the middle of her eyebrows disappeared as a result. She clenched her cane and continued to walk to the top of the divine bone altar.
