Although Luo Zheng slowed down, he was actually very high. After three hours, he had gone deep into the underground of 70000 miles.


    At this time, his breath had completely disappeared, like a tiny stone in the underground mud.


    "The hidden breath method of Fu Cang society is really wonderful. Using this hidden breath method, even the strong in the middle of heaven, it is difficult to feel me!"


    At that time, Luo Zheng inadvertently entered the cangning world, met Zhao Qian, the leader of the Fuchang society, and obtained the unique hidden breath method of the Fuchang society from him.


    Luo Zheng didn''t care too much before, but with the improvement of cultivation, he found the benefits of this hidden breath method.


    As long as you operate this hidden breath method, even the top experts are difficult to find.


    However, the only disadvantage is that when running the hidden breath method, you can''t run the true element violently, otherwise it will affect the Qi machine in the body and make the method ineffective.


    "Look, this must be the gathering point of Guixian building. It''s guarded by Tianji array!"


    When Luo Zheng went to the bottom of the earth, he immediately found that there was a huge array running where his eyes could reach.


    This array emits terrible flame energy, just like a huge fireball, which is more powerful than any earth lung fire. I don''t know how much.


    From the power of this array, it is at least the third grade of heaven.


    "Unexpectedly, the defense of Guixian building is so strict, and a powerful array is arranged, which is a little troublesome."


    Luo Zheng looks bad. Unexpectedly, he can''t enter the gathering point of Guixian building when he sneaks here.


    Originally, he also expected to find some evidence from here to prove the connection between Guixian building and Juling family, so that he could be more sure to convince long Zunxian emperor.


    But now it''s impossible. Luo Zheng can''t break the array by force, and it''s almost impossible for this powerful array to have flaws.


    "Now that you''re here, look first."


    Luo Zheng thought for a moment and then walked around the array and observed.


    Anyway, it won''t take much time to walk around the array. No matter what happens in the future, the Guixian building must be removed. You can know yourself and the enemy by understanding the power of the array first.


    "The flame of this array seems to be some kind of Yin fire. Once it touches the body, it is very difficult to extinguish and extremely dangerous!"


    When Luo Zheng approached the array, he felt not high temperature but cold Yin. This kind of Yin fire is more difficult to deal with than Yang fire.


    Although the thunder of destruction has great ability to break this array, it must be perceived by the experts in the array.


    "Well, what''s that?"


    Suddenly, Luo Zheng felt that there seemed to be a flaw at the bottom of this huge array. Although it was only very subtle, he could not escape his feeling.


    He moved and immediately sneaked towards the bottom of the array.


    "Well, what is this, a small sapling!"


    If there were any flaws in the array, Luo Zheng saw a small green tree with small arms growing from the ground.


    Except for the root and a small part of the trunk, other parts of this small tree are wrapped in the array, and the gap of the array is where the array contacts the trunk.


    What surprised Luo Zheng even more was that the little tree looked ordinary, but it was intact under the Yin Fire of the array. It looked full of vitality.


    "This little tree must be very small. It seems that the secret gathering point of Guixian building is established here. I''m afraid it has a great relationship with this little tree!"


    Luo Zheng felt that he might have discovered a great secret.


    He looked through the records of heaven in the sea of God, but found that there was no record of small trees in the refining roll.


    Originally, the refining instrument volume of Tongtian record recorded a large number of sharp weapons, Taoist and divine weapons, and the heavenly materials and earth treasures of refining instruments are all inclusive,


    This little tree has not been recorded in the Tongtian record, which proves that the value of this thing may even exceed that of an artifact.


    "Is it a divine tree?"


    Luo Zheng''s heart jumped violently, but Xuan was not there. Otherwise, he might be able to prove it with Xuan''s extensive knowledge.


    "By the way... Luo Riyue is the son of the God King. He must be well-informed in the divine position. Maybe he can recognize it, but not necessarily!"


    Thinking of this, he called Luo Riyue out of the no return door, "Luo Riyue, now we are in danger. Be careful to restrain your breath and never be found, otherwise it will be very troublesome."


    "This is the bottom of the ground, master. The array of the third grade of this day. The strong people in the later stage of Tianxuan territory are trapped in it. Is this the secret gathering place of Guixian building?"


    Luo Riyue immediately became lifeless, like a dead wood. He looked around and found that he was amazed.


    "Yes, this is the gathering point of Guixian building, but now the focus is not on Guixian building, but on that small tree."


    Luo Zheng stretched out his hand and said.


    "That is... The tree of the world!"


    Luo Riyue looked in the direction Luo Zheng pointed out, and immediately made a startling cry.
