Among the Dao Gates, not all of the high Dao can be called real people.

Only those who are profound, and who have become immortals, can be called real people, and of course, this immortal is only an earth immortal.

Every real person who has left a title in history is not an ordinary person, and they have all established their own Taoist system, which has been passed down to this day, such as Lan Yuan Zhenren.

Each of these real people has formed their own understanding of the Great Dao.

Yang Chenyu understands that he is now just a low-level earth from the god position, and in terms of cultivation, he may have crossed the threshold from the ninth rank and entered the ninth rank position, but his merits are not enough, and he has not yet been awarded by the residual heavenly dao.

There were all kinds of thoughts swirling in his mind, but Yang Chenyu was not slow at all in his hand, seeing that the earth fire had been completely finalized, he controlled the fire with his left hand, and with a slight grasp of his right hand, he threw a silver-white metal ingot into the raging earth fire.

The churning earth fire suddenly erupted several flames, engulfing the metal ingots.

A few minutes passed, and from Yang Chenyu's angle, it could be clearly seen that the metal ingots showed no signs of melting in the flames.

At this time, Yang Chenyu couldn't help but beat his forehead, when buying materials from Lao Sun, he only cared about the heat resistance and toughness of the materials, but forgot to consider whether the temperature of the flame could melt the materials.

According to Lao Sun's introduction, the melting point of this so-called tungsten titanium alloy is more than 3,000 degrees, which is far beyond the degree that the earth fire can reach.

The high temperature of the earth fire comes from the magma, and the temperature of the magma is mostly more than 2,000 degrees, so the temperature of the earth fire purified from this is not much higher.

It can be said that some special scientific and technological means can also reach a high temperature of more than 3,000 degrees, such as the high temperature of acetylene mixed oxygen combustion and so on.

However, that kind of direction was not suitable for Yang Chenyu's means of refining the Dan Furnace, and it was difficult to control it with divine thoughts.

That's it, Yang Chenyu's face trembled, and with a ruthless heart, he pulled out a trace of the Donglai purple qi in the spirit pool, integrated it into the earth fire, and then bit the tip of his tongue and squirted out several drops of essence blood.

As the essence blood sprayed into the earth fire, it suddenly caused a violent reaction between the earth fire and the purple qi from the east, and the purple gas from the east from the essence of the sun reversed the original mild qi, as if a scoop of gasoline was poured on the earth fire, making the flame of the earth fire rise, and the flames at the top of it suddenly licked on the top wall of the cave, and the hard rock instantly turned red, and a few drops of magma that could not stand the temptation of gravity immediately dripped down.

Yang Chenyu didn't pay any attention to the magma dripping from it at this time, but concentrated his mind on the metal ingots in the flames.

At this time, the earth fire was all pure white, and the silver-white metal ingots began to turn red and soften under the endless heat impact, and after a few minutes, the metal ingots finally began to gradually turn into a fiery red metal liquid.

Very good, Yang Chenyu nodded with a smile on his face, and threw another piece of metal ingot into it, and Shen Nian wrapped the metal ingot with the metal liquid to speed up its melting speed.

Hours passed, and the sky outside the cave became dark. And the last piece of metal ingot in the cave was also thrown into the earth fire by Yang Chenyu.

The spherical metal liquid was already half a person tall, but during this period, in order to maintain the momentum of the earth fire, Yang Chenyu had also consumed most of the Donglai purple qi that had not been completely absorbed in the spirit pool, and even the essence blood did not know how many mouthfuls he squirted.

At this time, Yang Chenyu's face turned pale, his eyes were full of exhaustion, and it seemed that he was going to fall to the ground in the next moment, and it was not a good thing that the essence blood was consumed too much.

However, since Yang Chenyu has persevered until now, it is impossible to give up.

"Transfiguration!"

With Yang Chenyu's soft snort, the metal liquid in the earth fire quickly changed under the traction of the divine thought, quickly turning from a spherical shape into the shape of a Dan furnace.

The shape of this Dan furnace, Yang Chenyu did not design it himself, but I don't know how much information he read on the Internet, and even the shape of the Dan furnace in some games was recorded by him one by one.

Of course, as for the Daomen classics written by Lan Yuanzhen, the detailed rules about the Dan furnace in the "Treasure Chapter" in the three articles of Daomen by Lan Yuan Zhenren have also been borrowed a lot from him.

Seeing the Dan furnace taking shape, Yang Chenyu didn't dare to slack off, success or failure in one move, and shouted: "Fixed!" With a finger of his right hand, the Dan furnace that was constantly rotating was suddenly fixed in mid-air.

Dozens of talismans that had already been placed on the ground flew towards the Dan furnace, and after spontaneous combustion, the red cloud patterns on it directly merged into the Dan furnace, and the endless earth fire was swallowed by the four mouths of the Dan furnace, and in a blink of an eye, the fire was extinguished, and a rain cloud wrapped the Dan furnace and turned into a spreading white mist.

After a long while, there was a light sound in the white mist, the white mist suddenly dissipated, and a four-legged four-mouthed, cloud-patterned silver-white Dan furnace appeared in front of Yang Chenyu, with a pop, the Dan furnace fell, and the four feet firmly grasped the ground, slightly emitting a residual heat.

"Okay, good!" Yang Chenyu laughed three times in a row, and he couldn't care about the fatigue on his body, so he pounced on the Dan furnace and stroked it up and down.

Dozens of red moire patterns are engraved on this silver-white Dan furnace, and the four mouths are the four mouths of the fire, the gas, the medicine, and the Dan.

Of course, in addition, there is a slag outlet at the bottom of the Dan furnace, if it is not too bad medicinal materials, this slag outlet is estimated to be used once for a long time.

The earth fire used to refine the Dan furnace before was also included in the Dan furnace as a fire source, and then Yang Chenyu did not need to supplement the earth fire, as long as the earth fire was stimulated with mana.

This Dan furnace is practiced, Yang Chenyu can be regarded as letting go of a matter of concern, but the Dan furnace is just practiced, and it still needs to be recuperated for a period of time before it can be used.

The warmth of the Dan furnace is different from Yang Chenyu's wooden sword, the wooden sword only needs Yang Chenyu to put it in his sleeve, and every time he practices, the mana fluctuates, and the blood rhythm warms up by itself. The Dan furnace warmth needs to be refined at the beginning, and the medicine is surnamed the furnace, and when three or four furnaces of the Dan medicine come out, the initial warmth of the Dan furnace is completed.

After that, even if the medicine of the wolf and tiger is refined, it will not cause too much damage to the Dan furnace, but every time the medicine of the wolf and tiger is refined, it is necessary to refine several furnaces of mild medicine to raise the furnace.

Yang Chenyu, who was too happy, fell asleep in the cave, the cold wind outside was fierce, and the cave was extremely warm, in the corner of the cave, Yang Chenyu had already set up a bed, and under the excessive loss of essence and blood, Yang Chenyu rarely slept lazy.

The next morning, Yang Chenyu walked to the entrance of the cave, Jiashan did not sleep all night, loyally guarded in front of the entrance of the cave, and saw Yang Chenyu immediately knelt down and saluted: "See the mountain god master." ”
