Below the entrance, there was a vertical passage that could not see five fingers. The black air wrapped Yang Xuan kept falling down for a moment. Soon, he came to a huge underground space.


    Yang Xuan, wrapped in black air, looked around and found that this was a huge underground palace.


    I don''t know when the palace was built. It can be seen that it has been for some years, revealing a simple taste.


    The palace was round and there were no other objects around it. Only on the wall were some strange patterns carved. Yang Xuan looked carefully, but he didn''t know the pattern.


    In the middle of the palace, there is a high platform, about half a meter high.


    Above the high platform, there is a pool about three feet around. Black liquid is surging in the pool, and a trace of black gas comes out from time to time.


    Yang Xuanxin was shocked by the smell of the avenue emitted from the black liquid.


    Wheel of the yellow spring!


    He immediately thought of the wheel of the yellow spring.


    It seems that the wheel of the yellow spring is made of the black liquid here.


    Just when Yang Xuan wanted to explore the black pool water, the black air moved. It wrapped Yang Xuan and rushed into the pool without any hesitation.


    The black pool water poured into Yang Xuan''s mouth and nose, but there was no feeling of drowning.


    Yang Xuan''s eyes were strange. From the black pool water, he felt how strange the shadow was, as if it were animals and plants of different shapes.


    Even, Yang Xuan''s ears faintly stood up to the sound of roaring and roaring.


    Black Qi sank into the pool with Yang Xuan, then went all the way down, and came to the bottom of the pool in the blink of an eye.


    At the next moment, a strange vortex appeared at the bottom of the pool.


    When Yang Xuan was ready to scan with his mind, the black gas accelerated instantly and wrapped Yang Xuan into the vortex.


    It was like passing through an unknown channel. I don''t know how long later, Yang Xuan suddenly found that he was completely in a weightless environment, surrounded by darkness and couldn''t see anything clearly.


    His mind scattered around, but no matter how he did it, all the places where his mind passed were dark and nothing else.


    A moment later, Yang Xuan felt a very cold breath coming to him.


    This breath, incomparably cold and dark, wrapped with a strong breath of death, surrounded Yang Xuan.


    Somehow, Yang Xuanmin felt that there was a strange trace of curiosity and exploration in this breath. It seemed that he was very curious about Yang Xuan and wanted to explore.


    Even, from this cold breath, Yang Xuan felt an emotion like fear and awe.


    After a few circles around Yang Xuan, it seemed that he didn''t see anything famous, so he carefully began to probe into Yang Xuan''s body.


    The black bead seemed to disappear completely. Even Yang Xuan couldn''t find any trace.


    The cold breath tentatively put a trace of breath into Yang Xuan''s body. After a circle, no abnormality was found.


    It seemed that some worried and cold breath hesitated again. Finally, it seemed that he had made up his mind and all entered Yang Xuan''s body.


    Black Qi entered the body. At the beginning, he was very cautious and careful. He seemed to be looking for something inch by inch. After he didn''t get anything, the cold breath stayed in Yang Xuan''s body and seemed a little disappointed.


    After a long time, it was ready to leave Yang Xuan''s body.


    At this point, the change protruded.


    A black bead hidden in Yang Xuan''s body suddenly appeared, appeared in Yang Xuan''s Dantian, and instantly sent out strange fluctuations, surrounded by the cold smell.


    As soon as Heizhu appeared, the cold breath suddenly turned pale, and he quickly wanted to leave Yang Xuan''s body.


    But then, a huge and incomparable majesty came out from the black bead, like a mountain.


    Yang Xuan was shocked. He had never seen Black Pearl emit such a breath. It felt like an angry emperor, like heaven and earth, full of inviolability in the face of his ministers who made mistakes.


    The pressure of Black Pearl rose steadily, like a king''s thunder and anger.


    Under this pressure, the cold breath trembled, retreated, retreated, shrinking smaller and smaller, and finally shrunk into a ball.


    I don''t know how long it took, the cold breath finally knelt down, like a minister who made a mistake, knelt down in front of the king and repented.


    Although he didn''t see it with his own eyes, Yang Xuan clearly felt the cold kneeling, like a courtier kneeling on the ground and praying for the king''s forgiveness.


    Watching all this, Yang Xuan''s heart trembled.


    He inexplicably had a feeling, as if this extremely cold breath originally belonged to a part of black bead.


    The pressure of black bead seemed to be so loose. From the cold breath, there was a feeling of great joy.


    The next moment, in Yang Xuan''s feeling, the extremely cold breath suddenly turned into a line, and then entered the black bead with a lightning speed.


    The black bead rotates rapidly, and the faster it rotates, the faster it rotates.


    Yang Xuan stared at the change of Heizhu and didn''t know why.


    I don''t know how long it took, the rotation of the black bead suddenly stopped, and then a light spot suddenly appeared inside it.


    Yang Xuan was about to explore his mind. When he explored the truth, a large amount of information suddenly rushed out of the black bead and directly entered Yang Xuan''s brain.


    For a moment, Yang Xuan felt that his head was about to explode and crack. It seemed that someone took a huge axe and chopped it on his head. He was dizzy and looked like Venus.


    For a moment, Yang Xuan felt as if he had come to a strange place. Here was a huge and incomparable space. Darkness was his eternal theme. In this space, there was a huge and incomparable building, which always exuded a simple and mysterious atmosphere.


    Countless shadows surrounded the building, circling and flying around, sending out bursts of bleak cries.


    They can''t stop hitting huge buildings with their bodies, and even turn themselves into fragments. They completely disappear without stopping.


    A huge breath filled the shadows, crazy and desperate.


    Suddenly, a pillar of light shot out of the huge building and went straight to the sky.


    In an instant, an extremely cold, extremely cold breath came out.


    The God of the yellow spring.


    Yang Xuan looked at the light column and was shocked.


    The smell as like as two peas of the Yellow River.


    At the next moment, a black vortex suddenly appeared on the sky. As soon as the vortex appeared, it began to fall to the ground outside the building, and then fell to the ground, turning into a black pool of water.


    A part of the shadow sent out huge cheers and rushed to the black pool. It was like a wanderer who had been away for many years and finally found his own home.


    At the moment when the black vortex fell on the ground, a strange pattern appeared on the wall of the huge building.


    Suddenly, a pure and incomparable soul force poured into Yang Xuan''s Yuanshen, making his Yuanshen grow up again.


    A very comfortable feeling made Yang Xuan almost groan.


    His Yuanshen grew rapidly, and soon he had grown into a child of seven or eight years old, more flexible and lively than before.


    With the strength of Yuanshen, his cultivation is also rising, more powerful than before.


    But before Yang Xuan could be happy, a large amount of information poured into Yang Xuan''s mind.


    A moment later, Yang Xuan''s eyes flashed, which contained shock and clarity.


    He finally understood.
