"Xianmen, white!" Yang Xuan took back his fingers, his voice was cold, and then added: "Yang Xuan''s senior brother."


    He was also a little surprised at the head of Biyun sect he had never met.


    Xie Tianke is the first person who can retreat from his life robbery. Although they haven''t really fought, with Xie Tianke''s heart-to-heart skill, they are already above the green snow queen, and not a bit.


    "What? Are you Yang Xuan''s senior brother?" before Xie Tianke spoke, Xie Tianji cried out in surprise and showed a happy face.


    He swept over step by step, ran directly to Yang Xuan and said, "you taught Yang Xuan''s mathematical knowledge?"


    Yang Xuan looked at him coldly and didn''t make a sound.


    Seeing that Yang Xuan didn''t speak, Xie Tianji scratched his ears and cheeks. He suddenly turned to Xie Tianke and said, "green robe, if this person''s attainments in numeracy are still above Yang Xuan, it will be of great help to us. It is very likely that he will wait for a hundred years and fight at this moment."


    Yang Xuan guessed that Xie Tianke and Xie Tianji seemed to be brothers.


    Xie Tianke pondered for a moment and suddenly said to Yang Xuan, "brother Bai, it''s really an accident to make younger martial brother die. It''s not our wish. It''s better to meet by chance. Brother Bai should be here at this critical moment. It''s better to participate in the grand event with us."


    Yang Xuan can kill the queen Qingxue. He has proved that his cultivation is not below them. Of course, brother Bai has no problem.


    This is the critical moment. At this time, he doesn''t want to conflict with Yang Xuan.


    As for the green snow queen, who cares about her? When she was alive, she was a master of humanity and their temporary ally.


    But when she died, it was just a body.


    No one will stand up for her.


    However, if he knew that biyunzong had been leveled by Yang Xuanyi, he didn''t know what reaction he would have.


    Before Yang Xuan answered, Xie Tianke cast an inquiring look at the old man who cut firewood.


    The old woodcutter looked at the green snow queen on the ground, then smiled and said, "I''m lucky to get brother Bai''s help!"


    Seeing that he had no opinion, Xie Tianke looked at Yang Xuan and said, "what do you think, brother Bai?"


    Yang Xuan''s eyes were cold. Although he had already sentenced Xie Tianke to death, this was not a good time to do it.


    In this strange place, his power was greatly reduced, and he was not very sure of killing Xie Tianke, let alone a mysterious old man who cut firewood next to him.


    And he also wants to see what the hell they''re doing here.


    He deliberately pondered for a moment before slowly nodding his head and saying, "OK!"


    Listening to Yang Xuan''s words, Xie Tianke secretly breathed a sigh of relief.


    Yang Xuan can give directions to kill the queen Qingxue. If possible, he really doesn''t want to be an enemy of such a terrible man.


    "This matter will start 150 years ago..." Xie Tianke told a secret that had been hidden for 150 years.


    In fact, the secret is very simple. Someone accidentally found the cave and worked out a way to enter the space. Then the three people learned that after entering here, they found that every 50 years, the lake water buried with columns will mysteriously disappear, and a mysterious metal platform and light curtain will appear at the bottom of the lake, on which the words of the world will be displayed, If you enter the correct password, you will open the mysterious channel and enter a mysterious space.


    What''s the password? The password is the height of the column and the diameter of the base.


    But there is a problem. This column is very mysterious. As long as it is within the lake, no warrior can fly, let alone get close to the metal column. Even anything close to the column will disappear mysteriously, so there is no way to accurately measure the height of the column.


    The base of the column is a circular platform. Like the column, people and objects are simply inaccessible, and there is no way to measure the width of the platform.


    Therefore, when they learned from Yang Xuan the shadow measuring method and the week measuring straight method, they would be ecstatic.


    Platform? Light curtain? Yang Xuan had a familiar feeling in his heart.


    But this puzzle is really evil and interesting.


    But there is a doubt. Since we can''t get close to the platform, how do we know the perimeter of the platform?


    "The length of one week of the round platform has been marked on the light curtain." Xie Tianji interrupted.


    I see, but Yang Xuan didn''t quite understand. Since this place is so mysterious, he doesn''t know what channel it will open. Why are the three factions so interested?


    When he asked this question, Xie Tianke didn''t answer, but said, "brother Bai, wait a moment. After the lake recedes, you will know why we are so interested."


    Wait a minute. I didn''t wait long. About half an hour later, a shaking force suddenly came from space.


    Then Yang Xuan saw a magical scene


    The water in the originally huge sea like lake disappeared quickly with the naked eye, but for a moment, it completely disappeared and exposed the bottom of the lake.


    The lake receded, and the exposed bottom of the lake also surprised Yang Xuan.


    There must be a lot of sediment and sundries at the bottom of the general lake, but the bottom of the lake here is as smooth as a mirror. You can''t see any sediment and sundries, and it''s very flat. If you have to describe it, it''s like paving a layer of ceramic tiles.


    In the center of the huge lake bottom, the lower half of the metal column is exposed, standing quietly on a circular platform.


    The material of the platform looks the same as that of the column, flashing blue from time to time.


    Yang Xuan already knew why the three factions were so interested.


    As the lake receded and the whole column was exposed to the public''s view, a momentum of extreme height, immeasurable grandeur and immeasurable greatness emanated from the column and filled the whole space in an instant.


    Under this momentum, everyone is as small as a mole ant. It seems that if you don''t pay attention a little, you will be crushed into pieces by this momentum.


    Earth!


    Somehow, the word immediately appeared in Yang Xuan''s brain.


    And he believed that when any warrior felt this great power, he would think of the word earth.


    This great force, as broad as the earth, makes people have the impulse to worship.


    Xie Tianke''s face showed fanaticism, awe, fear and excitement, which was extremely complex. He looked at Yang Xuan. It seemed that he was saying, now you understand.


    Yang Xuan understood. At this moment, he didn''t understand.


    "This way!" Xie Tianji said to Yang Xuan, and then took the lead to walk down the steps on one side of the stone wall.


    As long as you enter the lake, everyone''s power will be suppressed and can''t be used at all.


    Yang Xuan tried, and the aura could still flow, but the running speed was much slower than usual.


    The great lake was not deep, and its vertical height was only about 70 or 80 meters. When Yang Xuan fell to the bottom of the lake and stepped on the ground, he found that the whole bottom of the lake was a kind of metal and completely blocked his mind.


    After falling to the bottom of the lake, the people ran forward quickly. They couldn''t fly, but they still had no problem running.


    At a distance of about 300 meters from the pillar, everyone stopped.


    Then Yang Xuan saw an unforgettable scene.
