Hearing this, Luo Zheng couldn''t help nodding, stopped his action, and his face showed the color of thinking. After a while, he nodded and shook his head again.


    "What''s the matter?" Yujing asked strangely.


    "Miss Yujing is right. A strong body is the fundamental way. Strengthening the body is more important than cultivating the art of refining tools. However, it varies from person to person. Like our human race, our natural body is far less powerful than monsters, and even fierce animals without intelligence. If we give up refining tools, I''m afraid we won''t be far from destruction."


    "Therefore, I feel that there are thousands of avenues. As long as you choose your own way, there is no so-called one that is more powerful."


    Luo Zheng showed his white teeth and smiled brightly.


    "Maybe you''re right." Yujing thought.


    After an hour, Luo Zheng finally put away all kinds of things in the cave and filled it with six heaven and earth gourds.


    "Tut Tut, it seems that no matter how strong the skill of refining weapons is, it''s not as fast as robbing homes. If I find a few more transformed monsters like big black cow, I don''t have to worry about it in the future. Although many of those materials can''t reach the level of refining Tongtian 81 sword, they can also be sold for money. If it takes some time to refine them into magic weapons, I''ll make more money It''s too late. "


    Luo Zheng''s purse has never been so bulging as it is now. He is in a very happy mood. He is wondering whether to talk to Yujing and find several demon kings to fight the autumn wind in this Wanyao mountain forever.


    If Yujing didn''t support him and give him a hundred courage, he wouldn''t dare to enter the ten thousand demon mountain. Don''t say he wants to rob the demon king.


    The demon kings are all transformed monsters. Any one of them has the strength above the elder Xifeng. One finger can kill Luo Zheng.


    Thinking in their hearts, they came to the bottom of the cave. A huge stone gate, weighing at least tens of millions of kilograms, completely sealed the bottom.


    "It seems that the benefits are not trivial. With the intelligence quotient of the big black cow, he knows to seal the entrance."


    Luo Zheng was surprised. Unexpectedly, the big black bull knew how to defend.


    "It''s no use sealing this shameless stupid cow tightly."


    Yu Jing said coldly.


    When the golden claws beat out, the huge stone gate burst into pieces, and a dry and hot gas came to my face.


    With Luo Zheng''s cultivation, when he was flushed by the hot air, he felt his skin hot. When the hot air penetrated into the wound of his body, it was extremely painful. He quickly ran the real Qi to protect his body.


    Looking inside the stone gate, you can see that the fire is soaring and the heat is rolling. In front of you is a huge stone platform hanging in the air. Below, it is an underground magma river.


    "It''s strange. There''s no treasure in it. What''s the big black cow doing so mysteriously?"


    Luo Zheng walked in and looked around. He didn''t find anything valuable. He was surprised.


    "Well, what is this, a door panel?"


    Luo Zheng found that on the stone platform, there was an iron cast high platform, on which was placed a rotten iron block larger than the door plate, which was also connected with a long handle as thick as a tree pole.


    There are potholes on the iron door plate and the long handle. One side has a cutting edge, which looks a bit like a huge long handle broadsword.


    "Is this the baby of the big black cow? It''s so stupid!"


    Luo Zheng was stunned for a moment. Looking at the door plate, he couldn''t help laughing. He was angry and funny.


    This rotten iron gate plate broadsword is made of many precious materials. The materials are mixed in a mess regardless of category and attribute, which makes Luo Zheng feel speechless.


    "Young master, it seems that the big stupid cow is still in the same way as you. He is a master of refining tools."


    Yujing looked at the rotten door plate broadsword, giggled and said teasingly.


    "Miss Yujing clearly means that I''m as stupid as a big stupid cow."


    Luo Zheng held his forehead.


    That stupid cow doesn''t know what the art of refining tools is. He''s afraid he doesn''t even have a fire source. He throws the materials into the magma River to melt, and then mixes them randomly. Where is it called refining tools?


    "Well, you can refine that drop of blood essence here. I''ll help you with your arm. It''s estimated that you can refine it completely in one month."


    Yujing said.


    Luo Zheng thought for a moment and said, "Miss Yujing, I''ll try it myself to see if I can refine it. If not, how about you help me?"


    Although the energy contained in this drop of blood essence is incomparably powerful, Luo Zheng still has full confidence and refined it with the Tongtian sword array.


    "OK, I''ll help you protect the law."


    Yujing looks surprised and looks at Luo Zheng. Seeing that he always has a confident expression, he doesn''t say much anymore. He goes to a corner of the stone platform and sits and spits out.


    As soon as she vomited and accepted, the magma river below rolled up and condensed into real heat, which was inhaled into her body.


    Those hot gases entered from her mouth and nose, turned into a cloud of turbid gas and vomited out. After a while, her body began to emit hot gas, which was actually absorbing the hot gas of magma, refining and refining her body.
