"I see."


    Luo Zheng nodded slightly. Xuan became more and more mysterious. Up to now, he couldn''t guess what kind of existence it was.


    However, one thing can be confirmed that Xuan''s eyesight is very high, which is many times higher than Luo Zheng.


    Since Xuan gave a warning, he must be very careful!


    "Luo Zheng, your earth vein fire is extremely spiritual. Moreover, it itself is a special constitution and can be said to be a part of you. After the earth lung fire devours the demon flame, it is likely to produce wisdom. At that time, you can use a kind of God to seize the heart and poison, plant seeds in the wisdom it produces, get the method of external incarnation in the future, and then you can refine it into your external incarnation!"


    At this time, Xuan threw out a message that shocked Luo Zheng.


    "The incarnation outside the body? What is it?"


    Although Luo Zheng didn''t know what the incarnation represented, he also felt it was a big deal and asked immediately.


    "External incarnations are different from themselves. Some real peerless strong people may have external incarnations, and most of the external incarnations are transformed by their own special physique. Of course, the strong people with multiple external incarnations are not without, but there are few materials that can be refined into external incarnations, which depends on luck."


    Xuan explained a few words, but he didn''t say much about the wonderful use of the external incarnation.


    The fire cloud cave is really huge. Luo Zheng chased the fire of the earth lung and flew in it for a day without coming to an end.


    There was no life in the fire cloud cave, but Luo Zheng found many rare metal materials on some cave walls.


    Many metal materials are extremely valuable. They can even be used when you want to refine Tongtian 81 sword into a fairy in the future.


    "It seems that there was a powerful tool refiner in the fire cloud cave. Moreover, he refined immortal tools. These materials collected are not large in quantity, and their types and properties are different. They should be the remaining materials of the tool refiner."


    Luo Zheng murmured, the fire of the ground lung in front suddenly accelerated and flew forward with a cry.


    "The temperature around has obviously increased. It seems that it has been brought close to the magic flame. Now don''t scare the snake. If all the magic flames pour out, the plan will fail."


    He thought in his heart, stretched out his hand, and the fire of the earth lung immediately flew back into his body.


    Soon, the Qing emperor''s Wooden emperor''s Sutra ran, and Luo Zheng''s breath immediately disappeared.


    He is now like a small tree. Although it has life, it is extremely small and has no breath. No one can find it.


    After finishing everything, Luo Zheng flew forward.


    "That''s an open fire!"


    Suddenly, Luo Zheng''s body plummeted and fell behind a piece of raised metal, with a happy face.


    I saw a purple flame in the distance, shaped like a bird, beating constantly at this time.


    The purple flame suddenly turned into the shape of human body, but the body was much higher than the average human race, as high as three or four adults.


    "Gaga! This time, so many Terrans suddenly enter the fire cloud cave. It''s a good opportunity to kill. My lord doesn''t allow me to hunt Terrans!"


    This open fire from the sparrow showed its facial features, ferocious and twisted, like a purple devil.


    The magic flame of the fire cloud cave is derived from the fire source collected by the tool refiner in ancient times. The level of intelligence is different.


    Lique open fire is the source of seven kinds of fire. After transforming into a magic flame, it has greater power. It is suitable for the fire of the earth''s lungs to swallow.


    Luo Zheng''s heart moved. The green emperor Mu Huang''s vitality was slightly closed and immediately leaked his breath.


    "Gaga! Unexpectedly, a Terran warrior has sneaked into the depths of our fire cloud cave. You are looking for a dead end!"


    Suddenly, Lique Minghuo found Luo Zheng and laughed fiercely.


    It turned into a huge evil bird of this color. The flame rushed to the sky and fiercely jumped at Luo Zheng, "hahaha, the small human race dare to enter the territory of our demon flame family. I will devour your flesh and burn your bones to ashes!"


    "What a terrible temperature. I''m afraid I can''t cope with it with my current strength."


    Luo Zheng had already made preparations. He immediately turned Jinwu into a Jinwu, rushed away from the heat wave and flew out with all his strength.


    At this time, we must not disturb other demons, otherwise all the work will be wasted.


    Boom, boom!


    One chase and one escape, two figures fly away.


    At this time, on the square of Haotiancheng wusheng academy, more than 15000 wusheng students who entered huoyun cave to participate in the assessment have passed the assessment.


    "From the entrance to the exit, even if there is only juyuanjing cultivation, it can pass in half a day. Now it has been a day and a half. For an hour, no one has come out of the exit."


    Examiner Zhou stared at the transport array as the exit and sneered.


    At this time, Prince Han and others had already passed the examination, all unharmed, but Luo Zheng, who entered with them, did not appear.


    People with bright eyes have guessed that Luo Zheng has been unpredictable, and must have been killed by Prince Han and others.


    "Brother Wu, I hurt you. Don''t worry. I will find a chance to avenge you!"


    Princess Wan stood silently behind Prince Han and thought in her heart.
