Chapter 489

The reason why Li Mu borrowed the earth fire room from jiuzhongdian was that he considered that jiuzhongdian was the strong one of the real king level. First of all, there must be earth fire array and sky fire array in his cave, and the level was definitely not low.

The reason why Li Mu wants to use earth fire and sky fire is that according to records, xuanhuang iron, a holy material, can't be smelted by the true yuan fire of Li Mu's cultivators. The simplest way for Li Mu's cultivators to smelt xuanhuang iron is to use the power of the three fires of heaven, earth and man to form daohuo.

The so-called human fire refers to the true yuan fire of the cultivator himself. At this moment, Li Mu has fully met the conditions for refining Xuan pyrite, so he is naturally extremely excited.

"Turn on the fire of heaven!"

After looking at the sky fire array for a while, Li Mu raised his hand and played two true yuan lights, which directly disappeared into the Yin and Yang eyes of the black-and-white Tai Chi diagram in midair. With the integration of Li Mu's true yuan light, the originally bland Tai Chi diagram in midair suddenly lit up with black-and-white light, and then driven by the Yin and Yang eyes of the Tai Chi diagram, the black-and-white Tai Chi diagram rotated rapidly.

"Hum!!!"

With the rapid rotation of the Tai Chi diagram, a black-and-white light suddenly rose into the sky, directly through the layers of rocks above the chamber of secrets and into the outer sky.

"This guy!! what the hell is going on? Why does he have to use the sky fire array to refine magic weapons? It doesn't mean that he only needs to borrow the earth fire room. How can he activate the sky fire array now!"

Xu Ruqing, who was rushing to the valley after Li Mu escaped, suddenly changed her face when she saw the black-and-white light suddenly rising into the sky. She naturally knew that in ordinary days, she would refine some materials that were difficult to refine in the wine, or it would be used to assist in refining high-level pills, but she didn't expect Li Mu to actually stimulate the sky fire array.

Xu Ruqing's eyes turned, and then the wind step under her feet reached the extreme, and a few big strides came to the door of the cave in the wine. The corner of her mouth tilted, and she took out a token from her arms that was exactly the same as the token given to Li Mu in the wine, which was then inspired. But soon Xu Ruqing was angry, as she urged the token, the door of the cave did not open immediately.

"This boy! It's too much. He won't let me in in case I open the prohibition!!!"

After urging the token to fail to open the door of Jiuling cave, Xu Ruqing naturally knew the reason. It was because Li Mu used his token to open the door of Jiuling cave. The prohibition could be lifted only by holding the token from the Jiuling cave. This was specially used to prevent outsiders from interrupting when closing. Even if Xu Ruqing had a token in his hand, it was useless. Xu Ruqing's three corpse gods jumped violently for a moment, If she hadn't known in her heart that she couldn't break through the prohibition of opening the door of the wine spirit cave, she would have broken through the door and rushed in.

"Well, you dead wood, since you like to stay in it so much, the young lady will give you a surprise. Hehe, I think you won't beg me then!"

After being angry, Xu Ruqing suddenly showed a cunning smile. She no longer cared about Li Mu who was still in Jiuling cave, and flew directly towards her cave.

Not to mention how Xu Ruqing is going to surprise Li Mu, in the earth fire room in Jiuling cave, Li Mu looks at the black-and-white Tai Chi diagram floating in the air with a shocked face. This is the first time that he urges the sky fire array, and he has never known the so-called sky fire array before. At this moment, looking at the Tai Chi diagram rotating rapidly in the air, he rubbed his hands and took out a pile of dark yellow iron fragments.

With the excitation of the sky fire array, Li Mu soon found that the legendary sky fire array had a reaction. He saw strands of reddish gold sparks suddenly flying out of the Tai Chi diagram rotating rapidly in midair. At first, these reddish gold sparks were not many, only a few dots, but with the continuous rotation of the Tai Chi diagram, they constantly absorbed the power of the outside sun, These tiny sparks soon condensed into a fist sized reddish gold flame in the air below the Tai Chi diagram.

The fist sized reddish gold flame is still growing at a speed visible to the naked eye. As it grows, a burning sensation that makes Li Mu feel very uncomfortable soon covers his whole body.

"In the end, it is the legendary sky fire. The terrifying high temperature of the sun is really beyond the endurance of ordinary people. That is to say, my body is comparable to a five level high-level monster, and my blood has been several times stronger than before under the continuous refining of fiery wine for several years. Otherwise, it is really impossible to resist such a high temperature for a long time."

Looking at the reddish gold fire in the air in front of him, Li Mu couldn't help but whisper and attached great importance to the legendary sky fire. As time went by, the reddish gold fire in the air in front of Li Mu rose to a watermelon sized one. Seeing this, Li Mu raised his hand to the ground fire array in front of him, and a dark golden Zhenyuan light shone on the ground fire array, which stimulated the ground fire array.

As soon as the ground fire array was excited, a dark red flame suddenly appeared in a watermelon sized black hole in the middle of the array. The dark red flame was obviously much stronger than the general ground fire. From this color, it could be seen that it gave Li Mu a more terrifying feeling, and was actually comparable to the reddish gold sky fire group in the air.

As the earth fire burst out, soon, the dark red flame met with the sky fire group in mid air. The reddish gold sky fire group, as if it had the ability to swallow the flame, swallowed and absorbed a large number of earth fires into the fire group.

After absorbing a large amount of earth fire, the sky fire group rose to the size of a water tank, and its shape was also changing rapidly, from a round fire group to a twisted change, and finally turned into a seven or eight meter wide fire cloud, and its color also became dark gold.

With the fusion of the earth fire and the sky fire, a more powerful blazing high temperature came out of the dark golden fire cloud. The temperature was so high that Li Mu was caught off guard, and his eyebrows almost spontaneously ignited.

"It's really a big deal. It's only 30% of the power of the earth fire and sky fire array. If I adjust it to 10% of the power, how terrible the condensed flame should be!"

Li Mu touched his eyebrows, which didn't really burn, but vaguely sent out a scorching smell, and couldn't help swallowing a mouthful of saliva. This earth fire array and sky fire array can also be adjusted by psychic consciousness, because Li Mu didn't really use this method, so he didn't adjust too much power, just wanted to try it first.

With the continuous operation of the earth fire array and the sky fire array, the fire clouds in the air are more and more condensed, and the temperature emitted is also more and more intense. If it were not for the dark room full of cold jade, Li Mu wondered whether the surrounding walls would melt into magma.

Looking at the dark golden fire cloud whose temperature has reached the extreme, Li mulingzhi and Zhenyuan moved at the same time, throwing a piece of dark yellow iron the size of a watermelon on the ground beside him into the dark golden fire cloud.

As soon as the dark yellow iron was thrown into the fire cloud, the dark golden fire cloud soon burned the dark yellow iron red. Li Mu was very happy. He thought that he needed three kinds of flames from heaven, earth and man to refine the holy material dark yellow iron, but he didn't think that there were only two kinds of flames now, and the dark yellow iron actually reacted.

The happy look on Li Mu's face didn't last long, because as the dark yellow iron burned red, the watermelon sized dark yellow iron actually didn't react anymore, and remained in a red state.

Li Mu sighed helplessly. It seemed that there was nothing wrong in the jade slips left by huntian and Ren Xiaoyao. Holy materials such as dark yellow iron would be difficult to refine if they did not gather the three fires of heaven, earth and man. After Li Mu sighed for a long time, he sat cross legged on the ground. He really moved in his body and spit out his own yuan Dan.

After spitting out the yuan Dan, Li Mu raised his hand and made a decision against his yuan Dan. Under the flicker of a black gold aura, a black gold true yuan fire burst out of Li Mu's yuan Dan. Under the control of Li Mu, the black gold true yuan fire merged into the fire cloud in the air in front of him.

As soon as Li Mu's real yuan was integrated into the fire cloud, the original dark golden fire cloud suddenly changed dramatically, and it turned from dark gold to golden yellow, which looked extremely dazzling.

"This is the Dao fire condensed by the three fires of heaven, earth and man. It's really incredible. Although the injection of my Zhenyuan fire did not improve the power of this flame, it seems that the essence has changed, but I can't tell what specific changes have taken place!"

Looking at the golden flame in front of him, Li Mu said to himself, according to records, the flame formed by the convergence of the three fires of heaven, earth and man is called daohuo. The so-called "man follows earth, earth follows heaven, heaven follows Tao, and Tao follows nature", which is the origin of this name.

With the addition of the fire of Li Muzhen yuan, soon after, the dark yellow iron under the burning of the golden Dao fire really changed significantly, and the surface actually melted slowly. Although the speed was a little slow, there was also a significant change.

Looking at the effectiveness of his elaborate masterpiece, Li Mu was very happy. He moved his mind and raised the power of the earth fire array and the sky fire array from 30% to 50%. At the same time, the fire of Zhenyuan in Li Mu yuan Dan also increased its intensity. For a moment, the Golden Dao fire burned more violently, and the burning dark yellow iron continued to melt, forming drops of yellow juice in the fire cloud in the air.

After less than half of Zhu Xiang's time, Li Mu, who was originally happy because of the effect of daohuo on xuanhuang iron, frowned again. Although the earth fire array and the sky fire array can continuously capture the earth fire and the sky fire, his true yuan fire is not inexhaustible. The true yuan fire is also called the fire of Yuan Dan, which is catalyzed by the pure vitality in Yuan Dan, although it has infinite wonderful uses, But the loss of truth is extremely severe.

Feeling that the vitality in his yuan Dan was getting less and less, Li Mu finally sighed helplessly. He took out seven or eight Dan bottles, and took out a pill from the bottle and swallowed it. These pills were brought by Xin yu'er with Qi Tian. They were originally a spiritual elixir for refined cultivation, but Li Mu had no choice but to use them to reply to the true yuan.

It's not that Li Mucai's atmosphere is coarse. If the general true yuan is consumed, it's also feasible for Li Mu to absorb the vitality in the yuan crystal to supplement the true yuan, but it's different to urge the fire of the yuan Dan, because the loss speed of the yuan Dan to the true yuan is much faster than that of absorbing the vitality in the yuan crystal to restore the true yuan, and the only pill that can keep up with this consumption speed is the pill of refined cultivation.

Time passed quickly in the process of Li Mu constantly urging the fire of Zhenyuan to smelt dark yellow iron. In a blink of an eye, half a month passed. In the past half a month, the black-and-white light column appeared in the sky of Jiuling cave due to the operation of sky fire array has never disappeared
