When the old man entered the hall, the stone sword suddenly radiated a terrible light, and wanted to kill the old man on the spot.


    Looking at the light of the stone sword, the old man''s body changed dramatically in an instant. His flesh and blood skin and his clothes were in the shape of jade in an instant, as if the whole person had become a strange jade statue.


    The light of the sword shot on the old man''s jade like body and was broken by the old man''s hand.


    "Fear!" Zhou Wen was surprised that the old man was able to break the light of the stone sword. He was obviously a strong man of fear level.


    Stone sword without hesitation again scabbard, with invisible sword light again cut to the old man.


    The jade statue like old man suddenly put out his hands to hold the stone sword. For a moment, the stone sword could not be stabbed for half a minute. However, the old man could not fight back the stone sword. One person and one sword were frozen there.


    "Who is this old man? How can you bear the power of stone sword Liu Yun was surprised.


    But Zhou Wen didn''t say a word. In a flash of his body, he rushed into the palace.


    Liuyun also reflected, a bite, also rushed into the palace.


    The stone sword and jade statue are in a stalemate. They have no spare power to stop Zhou Wen and Liuyun. In the blink of an eye, they have rushed into the hall with bamboo slips.


    Seeing that the old man was still in the middle of the stone sword deadlock, Zhou Wen didn''t rush inside. He took a roll of bamboo slips from the shelf and opened it.


    It turns out that what is written above is the law. Then I picked a few volumes of bamboo slips on different shelves and found that all of them are the law. I can''t help feeling a little strange.


    "It''s said that the Qin emperor believed in the immortality advocated by warlocks. Originally, he thought that the books buried with him should be related to alchemy and immortality. Unexpectedly, they were the books of the law." As he walked, Zhou Wen looked at the books at random and found that there were no records related to alchemy in these books. All of them were rules.


    "Younger martial brother, why don''t you go now? What''s good for those bamboo slips?" Liuyun also looked through several volumes and found that they were all legal provisions, so he was not interested.


    Zhou Wen put down the bamboo slips and quickened his pace. He and Liuyun walked all the way to the end of the palace. There was another gate, but it had been opened. It was obviously a masterpiece of jingdaoxian.


    There was a screen made of jade inside the door to stop them. They walked around the screen and were surprised by the scene.


    The ground was full of broken bronze and jade fragments, as if they had experienced a great war, but they did not see human figures or the gateway to other places.


    "There may be a secret door." Liuyun said while groping on the wall, trying to find out where the secret door is.


    "Don''t look. Look at the water in that pool. Is there something wrong with it?" Zhou Wen pointed to a pool and said.


    The water in the pool was black, like ink, but there was no peculiar smell. It should not be blackened because of deterioration.


    "You mean there''s a road under this pool?" Liuyun looked at the pool, but the water in the pool was too dark to see clearly.


    "I don''t know if there is a way down here, but there should be no secret door in this palace." Zhou Wen has scanned the whole palace with listening. If there is a secret door, he can''t find it.


    "Going down?" Liuyun hesitated.


    "I''m afraid I have to go down." Zhou Wen said, looking out, he saw that the old man had rushed in.


    Different from the jingdaoxian who rushed in before, the stone sword also chased in. The light of the sword on the stone sword destroyed almost everything.


    Without hesitation, Zhou Wen jumped into the pool with ya''er in his arms.


    It seems that there is a dragon around his body, repelling the black water from his body.


    Liuyun clenched his teeth and jumped down with Zhou Wen.


    Strange to say, the black water in the pool seems to have no buoyancy. As soon as they jump in, they quickly fall, and the falling speed is faster and faster, as if there is a force pulling them below.


    Bang!


    When Zhou Wen and Liuyun were down-to-earth, their strong impact almost broke their leg bones.


    Before they could see clearly the environment in front of them, two shadows fell from their heads. One was the old man like a jade statue, and the other was the stone sword.


    As soon as the stone sword falls down, thousands of sword lights radiate from the sword body, covering all areas nearby.


    Zhou Wen and Liuyun dodged quickly. Zhou Wen turned over and hid behind a huge object. The object blocked the light of the stone sword. He watched the light of the sword bombard it like a rainstorm, but he didn''t smash it.


    Only then did Zhou Wen find out that the thing he used for refuge turned out to be a huge alchemy furnace. The alchemy furnace was more than ten meters high, and the whole body seemed to be made of copper.


    However, it was not the bronze often seen in that era, but a kind of red copper.


    The sword light strikes the red copper furnace and makes a noise, but it can''t hurt the furnace.


    When Zhou Wen looked inside the furnace, he found that the furnace was full of flames. The flames in the furnace were white, and the temperature was too high to imagine. The copper furnace felt warm, but it didn''t feel hot.


    "Strange, I''ve never heard that the Dan furnace is on fire. It should be heated by the burning flame below. But the Dan furnace is on fire inside. What''s the reason?" Zhou Wen felt a little strange.


    When Shi Jian was fighting with the old man, Zhou Wen took the opportunity to look at the surrounding environment and was surprised to find that it was the top of a mountain.


    In the dark and huge underground space, a mountain occupies a lot of space. They stand on the top of the mountain, only 20 or 30 meters away from the stone dome above.


    It was dark all around, because the space was too big and there was no light. Only the flame from the air hole of the red copper furnace was shining, which made the distance even darker.


    All the areas that can be sensed by listening attentively are empty. There is a cold wind blowing from far away, and the wind is still strong. The clothes on Zhou Wen''s body are stuck to his body, and the cold wind goes straight into the bone.


    "Where did jingdaoxian go?" Zhou Wen holds ya''er with his back to the cold wind. After searching for a long time, he doesn''t find jingdaoxian.


    Liuyun also rushed to the back of the Dan furnace, and after meeting with Zhou Wen, he said: "there is nothing on the top of the mountain, there is only one dan furnace. Do you think it is the immortal pill refined by the emperor in this Dan furnace?"


    "I don''t think so. Otherwise, why isn''t jingdaoxian here?" When Zhou Wen was talking, he suddenly heard a huge rumbling sound in the distance, like thunder.
