The fiery red molten iron that exuded high heat was slowly poured into the mold, which was the smallest mold that the master and apprentice had ever made, only a foot high. But the material is very different.

Earlier, Li Hong suddenly had a whim, thinking that the main reason why the Dan furnace could not be started was not because the spirit gathering array was not carved correctly, but because the materials of the Dan furnace were not good enough.

In Yue Changzi's mind, since it was just a Dan furnace for alchemy, of course, he didn't use the best materials for making flying swords, such as extraterrestrial gold and fine iron, he only used agent steel (note). But this dose of steel is also an extraordinary thing in the mortal world, and the price of one or two doses of steel is equivalent to the same two golds, and it has always been a material for making the best swords such as "Juque" (Note). Yue Changzi felt that the agent steel was completely qualified to build the Dan furnace.

However, Li Hong thought that the Dan furnace of refining the earth-grade Dan could not be regarded as an ordinary Dan furnace, but should be treated with the same magic weapon, and the agent steel would definitely not work.

The master and apprentice muttered for a while, Yue Changzi endured the heartache, and found fifty catties of the secret collection of heavenly gold essence iron in the instrument hall - fifty catties of heavenly gold essence iron can be used to build thirty or forty magic weapon-level flying swords;

When this good thing cooled down a little, the part that made Li Hong breathtaking.

But seeing Yue Changzi's palms quickly spinning left and right, the mold was quickly removed, and the red and hot Dan furnace model inside that had not yet cooled flew into the air and slowly rotated in the air. The whole mass of iron crystal is crystal clear and fiery red. The prototype of the Dan furnace has appeared.

Yue Changzi quickly pointed out with his ten fingers, and while the Dan furnace had not yet cooled down, he quickly engraved the spirit gathering array on the outer wall of the Dan furnace, and turned the Dan furnace upside down - the furnace lid was still a round fiery red hole at the moment, and the furnace lid was not installed. Through this hole, you can see the four small Dan rooms in the complex, which are the medicine room, the warm pill room, the fried pill room and the Dan room, and there are passages between the four circular small Dan rooms in turn. Through the holes in the lid of the furnace, Yue Changzi first quickly engraved the main spirit gathering array at the very bottom, and quickly rotated the Dan furnace model in turn, forming the medicine room, the warm pill room, the fried pill room, and the pill room, and carved the "small fire array" on the walls of the first three pill chambers - to convert spiritual power into heat to increase the furnace temperature and increase the speed of alchemy, and carved the corresponding "spirit array" - so that people outside can adjust the heat and master the alchemy steps in a timely manner.

All the talismans inside were engraved, and Yue Changzi finally poured the last bit of molten iron left in the crucible into the model of the furnace lid, and after it was a little cold, he quickly took a drink from the gourd containing the ice and cold spring next to it, and the sound of fluttering sprayed on the stove lid, and he quickly took off into the air and installed it at the mouth of the furnace. With the mobilization and rotation of spiritual power, the hinges reserved for the furnace mouth and the furnace lid were immediately tightly connected.

"It's done!" Yue Changzi twisted his beard and smiled, and with a wave of his right palm, the Xiao Dan furnace fell into the ice and cold spring that had been prepared a long time ago.

Shhoo - misty green smoke came out, and the entire Fire Jade Cave was filled with water vapor, but I saw a bright small Dan furnace soaring into the air and taking off in front of me.

The Dan furnace is one foot high, three-legged, looks crystal clear, the color is yellow with red, and the whole body is full of red and bright fire aura wandering in the whole furnace body, and the glow is as dazzling as the sun. This Dan furnace looks beautiful and extraordinary. That's just the magic weapon.

The master and apprentice placed the little Dan furnace on the ground and walked around it several times with satisfaction, agreeing that it was the best and most satisfying one ever made.

Now, the most important link is coming, it depends on whether it can be activated after inputting spiritual power.

Li Hong stretched out his hand: "Master, you come!"

When it came to the end, Yue Changzi was scared, "Don't dare to be a teacher, if it's a waste ...... again"

"Sample! I'll come!" Li Hong sneered loudly, and pressed his hand on the wall of the Dan furnace, regardless of the input of consciousness in 3721. A burst of red light flashed, and only the buzzing sound was heard, and the Dan furnace was really activated.

"Haha! Even I can refine the pill!" Li Hong laughed, eager to pounce on it and take two bites.

Yue Changzi couldn't hold back any longer, and kicked Li Hong to the side: "Go! Your special spiritual power is not good at all, now it's your turn to be a teacher!"

His palms shook, and the spiritual power came out through his palms, and a steady stream of them entered the Xiao Dan furnace through the air. I only heard the humming sound inside getting louder and louder, the whole furnace body was shaking, and there was a trace of green smoke coming out of the gap in the mouth of the furnace lid.

Li Hong shouted in fright: "Stop! There are no herbs in it yet, and the light burning of the Dan furnace will burn out!"

Yue Changzi's hand shook in shock, and he stopped inputting spiritual power in time.

The two of them cautiously leaned over to lift the lid of the stove and look inside, while slowly breathing a sigh of relief.

Dan furnace is fine at all.

Li Hong scratched his scalp and muttered: "It seems that even if the Dan furnace is refined, the speed and amount of medicine and the amount of spiritual power input and time must not be wrong at all, otherwise it will definitely not be the Dan that will be baked, but the waste medicine residue!"

Yue Changzi was stunned when he heard this, he touched his unevenly burned beard and said with a sad face: "This is really stumped for me! You call me a refining weapon, and tell me to sit there and study alchemy with a water mill, don't you want my life!"

Li Hong smiled: "It has nothing to do with you at all. Hehe, Yun Jiuzi's uncle and ancestor are the most suitable candidates. ”

The two looked at each other and laughed. One was shirtless and the other was wearing a fire jacket full of holes, and he didn't even clean up his body, and flew directly out of the fire cave to find Yun Jiuzi after passing the Xiao Dan furnace.

Yue Changzi's eldest disciple Ling Yizi finally saw the master and the junior brother out of the customs, but saw the two of them laughing like madmen and dragging a shiny object away from the front like a whirlwind.

He fixed his eyes on the thing and saw that it was a Dan furnace, and smiled happily: "It was really drummed out by the master and the little junior brother, the two of them are really good! Hmph, in the future, we will leave the door to refine the pill by ourselves, we will not ask for help!"

He proudly sang a little song and bragged everywhere.

The alchemy trio was officially established, and Yue Changzi was ordered by Yun Jiuzi not to leave—because to try this Dan furnace, the bad things needed him to improve at any time.

Yun Jiuzi went to Lingxuzi to ask for a huge amount of messy herbs, which was called a trial. So Ghost Stream's hut became a temporary alchemy room for Jiulimen, where smoke rose to the sky all day long, and from time to time there were loud explosions and strange noises. Frightened, none of the fierce ghosts in the Golden Lantern Gorge dared to approach, and automatically avoided at least thirty miles.

The people who left the door were all shocked, at first it was just the elders who went to see the excitement, and then as long as the disciples who knew the sword would visit, in the end, even Lingxuzi couldn't sit still, and went to inspect it in person, and when he got there, he almost laughed.

But seeing the crowds of people, all the people who came to visit and watch the excitement were all instructed by the alchemy trio. Most people are sorting herbs, washing them and drying them. If Yun Jiuzi's hut has become a Dan room, then the open space outside has become a herb preparation place, and many disciples have volunteered to help out in an endless stream.

Only the elders who have cultivated above the Jindan stage are allowed to enter the hut, and only four can enter at a time - there is no other reason, it is up to them to inject spiritual power into the Dan furnace, but there are too many people and it is not good, Yun Jiuzi is panicked. Therefore, the captain of the group lined up outside the door to enter, and at the same time discussed it with great interest.

In the hut, Yun Jiuzi was lying on his broken bamboo chair, comfortably shaking the broken pu fan that came from nowhere in the hot "Dan room", and pointed with his hand: "Go on! Don't stop, you must remember that you can only inject slowly, and you must not be fast or in a hurry! Hmph! Who is going to break our precious Dan furnace, wait for the punishment hall to receive the punishment yourself!"

"Yes, yes!" the hot and sweaty elders were submissive, and they didn't dare to slack off for a moment. The four of them each occupied one side, and slowly injected spiritual power into the wall of the Dan furnace according to their words.

The baby Dan furnace buzzed, trembling slightly, and bright red light visible to the naked eye flashed from the wall of the Dan furnace. The smell of medicine gradually spreads.

Li Hong, an important member of the trio, hung high above the Dan furnace, his legs hooked on the beams of the room with his eyes closed, not knowing what he was doing.

After a while, Li Hong suddenly shouted: "That's enough! Now listen to my orders, stop everything! Prepare to go out!"

The four elders suddenly became nervous, listening to Li Hong shouting, "One, two, three, now!" and immediately withdrew their hands, honestly and obediently stretched their necks to look at the Dan furnace.

Yun Jiuzi Huo Ran jumped up, Pu Fan towards the Dan furnace a little, only to see the red light, the Dan furnace lid automatically opened, the air was full of too thick to dissolve the medicinal fragrance, in the sound of the roar, black things automatically jumped out of the Dan furnace, and they had already been copied in the hands of the elders who were waiting beside them.

Several big heads immediately got together, and someone praised it: "Okay! This furnace is much more beautiful than the previous one!"

It was only then that no one noticed Lingxuzi, Yun Jiuzi's eyes flashed, and he said lazily: "The head master nephew, you are here." ”

Lingxuzi couldn't hold back his excitement, walked to the group of elders, reached out and took a "spirit pill", and immediately frowned slightly.

"This—is it also a elixir?"

"Count, why not!" the four elders said in a gossipy manner: "You don't know yet, master, at the beginning, what we refined was such a regular circle, all of them were charred black flat grains like rat feces, and they couldn't even smell the scorched ones. Now, it's a lot better! You see, this is obviously Bigu Dan!"

"That's it, another furnace, the management and insurance are really successful!"

Several elders spoke incoherently excitedly, and shouted: "Come on, come on, open another furnace, this time it will be successful!"

Next to him, Yue Changzi was writing hard in a book: "The two hundred and eighty trials, close to success." This time I refined the 'Bigu Dan' and found that the Wen Dan time should not exceed two hours. ”

He solemnly closed the book, thrust the pen behind his ear, and shouted, "Now that the two hundred and eighty-first trial of Bigu Dan begins, who is willing to provide spiritual power to the Dan furnace?"

"Me!"

"Me!"

"Me!"

There was a long line of elders and elders at the door, all shouting.

Looking at this scene, Lingxuzi suddenly felt that his eyes were sore, and his chest seemed to be blocked. There is such a group of people, why don't you worry about leaving the door, why don't you worry about the elixir!

He laughed, rolled up his sleeves and said with great interest: "Now I am counted as one!

Three hours later, the first furnace of the Nine Leaves Gate was refined.

Waves of cheers rang out over the entire Sky Snatching Valley.

Yue Changzi solemnly wrote down in his alchemy notes: "On August 19, the first furnace of Jiuli was self-refining and Gu Dancheng. ”

Note: Agent steel is the ancient name for high-carbon steel, see Song * Shen Kuo's "Mengxi Writings"
