"In the heart refining method, there is a distractor refining technique with one mind and two functions. I haven''t had enough cultivation before and have been afraid to try it. This time, I don''t need any skills to refine straight spirit sword and dark cloud sword. I can try this distractor refining technique."


    Luo Zheng looked at the two materials in front of him and thought in his heart.


    "However, my earth lung fire is still too weak. Although the quality of these two materials is far less than that of Ziji divine iron, they are not bad. If you refine these two materials at the same time, you still need to improve the power of earth lung fire."


    "Earth lung fire!"


    Thinking of this, Luo Zheng drank softly, and a four inch black flame rose from his body.


    "If you can improve the power of the earth lung fire, it will not only have a great impact on the refining tool, but also have a great power when used in battle, and can have unexpected effects."


    Luo Zheng looked at the small fire in front of him and thought about it in his heart.


    The only way to improve the power of the earth lung fire is to let the earth lung fire devour the cold attribute or the fire attribute.


    After thinking for a while, Luo Zheng selected the materials of heaven and earth rings.


    Green fire sand, bright flame stone, flaming Feather Crystal iron


    Luo Zheng picked out some fire and cold materials that were not very useful.


    Hoo Hoo!


    This little earth lung fire soon found these materials, conveyed a happy mood to Luo Zheng, and jumped violently in front of Luo Zheng, as if expressing something.


    "Well, these are for you."


    Although the earth lung fire has no spirit, it grows out of Luo Zheng''s body. It is connected with him and has an inexplicable telepathy. Luo Zheng also said after feeling the emotion of earth lung fire.


    Hoo Hoo!


    The pure black ground lung fire beat again, that is, it rushed down at several materials, and then burned violently.


    "What a fast swallowing speed!"


    Luo Zheng looked at the fire of the earth''s lungs and swallowed a small pile of green fire sand. However, after a few decades of rest, he disappeared cleanly and was surprised.


    However, this black flame, with theout any sign of the staying, rushed towards several bright flame stones.


    After several decades of rest, several bright flame stones were digested without leaving a trace.


    "Good guy, this is a loser. I got these materials from the five element chain array in the blood demon space. Although they are not the best materials, they can also refine inferior treasure tools. It''s no problem to exchange them for a few gold E pills. They disappeared so quickly. It''s a loser!"


    Luo Zheng opened his eyes and looked at the fire of the earth''s lungs. He said in pain.


    Moreover, he swallowed several materials one after another, and the fire of the earth lung didn''t grow much. It kept the original state, which made him have some doubts in his heart.


    However, in half an hour, the seven materials Luo Zheng took out were swallowed up.


    But the fire of the earth lung didn''t grow up at all, which made Luo Zheng feel extremely depressed.


    "How could it be like this? After the fire of the earth lung swallowed the fire source of gold glaze and burning scorpion last time, it obviously grew up. Why is it not long this time?"


    Luo Zheng frowned and fell into meditation.


    "By the way, can it be so..."


    After a moment, Luo Zheng suddenly brightened his eyes and thought of a possibility. The last time the fire of the earth''s lung swallowed the fire source of the burning scorpion and the fire gold glass, it had swallowed a large amount of the vitality of the Tianyu cold ice of Yuling.


    "The seven materials I just took out are all materials with fire attribute. Does it need to devour two kinds of vitality at the same time to improve the power of earth lung fire?"


    Luo Zheng thought of this and immediately looked through the materials of the heaven and earth ring.


    After a while, he just took out several materials with cold properties, such as dark ice sand, cold jade crystal, water mirror stone


    "Quickly swallow these too. These cold materials are many times more precious than fire materials. If your power can''t be improved this time, I''ll lose a lot!"


    Luo Zheng said to the fire of the earth''s lungs like black flowers.


    Between heaven and earth, materials with various attributes are the easiest to obtain, while materials with wind attributes, thunder and electricity attributes, cold attributes, yin and Yang attributes are much more difficult, and the price is several times more expensive.


    Hoo Hoo!


    The fire of the earth lung sensed those cold materials, once again conveyed a happy mood to Luo Zheng, and immediately began to devour them.


    "Although the fire of the earth lung is called fire, it can refine all things in heaven and earth. It does not only contain the attribute of fire, but the attributes of fire and cold. Therefore, if you want to improve the power of the fire of the earth lung, you can''t succeed only by refining the material with the attribute of fire."


    Sure enough, after the fire of the earth lung swallowed a cold jade crystal, the flame, which was only four inches in size, immediately increased by one point.


    Although this change was almost difficult to detect with the naked eye, Luo Zheng could feel the joy conveyed by the fire of the earth lung.


    Half an hour later, after the fire of the earth lung swallowed all the cold materials, it finally grew to four inches and five minutes in size.


    "You should be able to try the distractor technique now."


    At this time, Luo Zheng''s eyes also swept to the two materials of Tiansha spirit earth and Nebula elephant gold.
