He even found a huge palace ruins in this undersea mountains and rivers.


    The whole palace is thousands of miles big, bigger than ordinary cities!


    And almost every one of these buildings is incomparably magnificent and gorgeous.


    Although these architectural relics have been dilapidated at this time, they still give Luo Zheng a feeling like a divine palace.


    However, Luo Zheng spent a full day in this palace ruins. He even searched carefully under the ground, and there was no harvest.


    This palace is too old, too old, as if it were a prehistoric thing, as if it had been handed down from ancient times!


    "After searching for so long, I have searched many places. I have searched for nine times out of ten in the middle area of the map. Moreover, I have searched for that palace for so long, even underground. Can the array eye be on the edge of the array!"


    Luo Zheng thought for a long time. "By the way, except for all the underground of the palace, I have looked for it. Is there no underground of the place? Is the array eye under the underground?"


    With a sudden jump in his heart, he immediately extended his divine consciousness to the underground and searched all the way.


    "What is this?"


    But after a long time, Luo Zheng''s heart jumped violently. He found a drop of water!


    At a place thousands of feet deep underground, when the main space of the sword was swept, he found a drop of water!


    It''s not surprising that there is water underground. What''s more, it''s under the sea. It''s more likely that water will penetrate into it.


    However, Luo Zheng found that this drop of water was abnormal!


    "It''s so deep. If it''s just swept by divine knowledge, it can be ignored. It''s just as a drop of ordinary water. Fortunately, the sword master''s space has subtle power to find that this drop of water is abnormal!"


    Luo Zheng was deeply grateful.


    "Xuan, three thousand and five hundred feet to the right, break the ground. At the bottom of the ground, there seems to be something!"


    Luo Zheng said.


    "OK, let''s go down and look for something!"


    Xuanmeng speeded up, then reached the place designated by Luo Zheng and drilled into the ground.


    "It''s so hard. What''s this? It''s made of Xuanwu gold crystal. How can this kind of thing appear here? It seems that it''s really strange here!"


    Xuan quickly drilled, and when he reached 800 feet, he suddenly stopped, surprised and happy.


    "What, Xuanwu Jinjing, there is such a thing, one of the hardest materials in the world!"


    Luo Zheng was shocked and understood that he was absolutely right this time.


    Even if a drop of water is not an eye, it is definitely something different.


    Xuanwu gold crystal is 100 times more precious than jade, forbidden real gold, and purple refined gold. It is rare in the world.


    Luo Zheng once thought that when he reconstituted the sword body for Shengxue in the future, he would use basaltic gold crystal as the material, but he didn''t find it in Zhongzhou city.


    This time, no basaltic gold crystal was found in the secret place. Unexpectedly, it appeared here.


    "Originally, I planned to use the extremely gold field of nothingness to refine the sword body for Shengxue. Now it seems that I don''t need it. This Xuanwu gold crystal is the best material. It''s not too much to call it divine material!"


    Luo Zheng had long wanted to refine the winning snow sword, but he suffered from the lack of suitable materials.


    However, this is not the time to consider these. How to break through the Xuanwu gold crystal and find the "drop of water" is the most important thing!


    Xuan walked around the drop of water and found that the Xuanwu gold crystal was like an egg shell, and that drop of water was the egg yolk inside!


    "Master, let me have a try!"


    Suddenly, the king of the hook snake moved, rushed out of the small tower and turned into the big hook snake, which was cutting towards the basaltic gold crystal!


    Click! Click! Click!


    The king of hook snake''s fin knife crossed over the Xuanwu gold crystal, and there was a burst of spark. Then I saw that the hook on his fin knife was broken one after another, and even the edge of the fin knife was blunt!


    The Xuanwu Jinjing is unharmed!


    "It''s really powerful. The king of hook snake can even cut through the extremely gold field of nothingness. At that time, his strength was far worse than now. He had no way to take this Xuanwu gold crystal!"


    Luo Zheng was in the small tower and was shocked to see this scene.


    "Master, I''m afraid it''s impossible to cut this thing unless I''m at the top of my cultivation!"


    The king of hook snake returned to the small tower dejectedly and said.


    He is a weapon of the emperor''s way refined by the demon emperor of Youtian. How powerful it is. He has no way to take a piece of material. Instead, he was hurt by it. He was hit too hard!


    "Luo Zheng, with my current strength, it is impossible to break the Xuanwu gold crystal. The king of hook snake is right. This is a real divine material. Unless it is a real congenital Taoist instrument, it is impossible to break it!"


    Xuan also said.


    "If we can''t break it, we have to break it. We finally see hope. Entering the ground has consumed huge energy. If we fail again, we may really die here!"


    Luo Zheng said.


    Now time is running out, and less energy can be consumed for Xuan!


    "Now the only hope is the red melting blood fire. I enter the peak of the casting God realm and understand the hand of the fire emperor. The red melting blood fire has a trace of power!"
