"Grandpa, who are these men and women?!Even if they are five- to six-star level pill pharmacists, you don't need to personally assess and test them with Grandpa Huo, right?!" Seeing that Du Long picked up the refining formula and read, Mu Qiao's little beauty couldn't help but pull Mu Xuan's elbow and asked.

At this moment, Xia Qinglian was sitting on the exercise to recover her strength, Du Long was watching the six-star refining formula again, and Mu Xuan, who happened to be idle, stroked Bai Xu and replied with a smile: "This man's name is Du Long, and the woman's name is Xia Qinglian, and the two of them seem to be husband and wife!"

In the flame test in the main hall on the first floor of the Danmeng, the flame is in excellent condition, and your cousin Hibiscus brought the two of them here, and it happened that grandpa met the old man with fire, so he helped him test the flame and the Yuan Shen form, and it turned out that it was actually a lotus flower and a sword-shaped Yuan Shen form!"

"Oh my God?!" After listening to her grandfather's explanation, Mu Qiao covered her mouth on the spot and exclaimed, "Miao Lian and the sword-shaped soul appeared in our Bibo City at the same time, and they also appeared on the two of them at the same time?!"

In the No. 1 test hall, although many people did not dare to approach the red and white elders, they also pricked up their ears to listen carefully to their conversations, and the existence that could enter this test hall was all with the identity of a star pill pharmacist, and they naturally understood how rare the lotus form and sword-shaped primordial god were!

Therefore, everyone's eyes widened in shock, and they finally understood why the two respected branch alliance masters would appear here and here together to test the star strength of their elixir master and immortal craftsman for the two young people!

In the fifteenth test room, Du Long carefully looked at the refining formula in his hand, which was a six-star immortal weapon refining formula called Fire Dragon Slash, which recorded the usage and dosage of various ore materials, as well as the steps and timing of smelting.

Various metal ores are smelted together through a special technique to form an alloy with multiplied hardness and toughness, and then condensed into a fire dragon slashing sword!

This process requires a flame intensity of at least six stars, otherwise it will not even be able to smelt several of these important metal ores, let alone others!

After successfully smelting the alloy battle knife, it is to carve a six-star level magic circle on the battle knife, which is also the biggest problem for Du Long, he doesn't know what a six-star magic circle is, and the formula simply says that you need to carve an attack circle equivalent to the six-star level!

Seeing this, Du Long secretly frowned at the same time, he also asked for help from the bottom of his heart, and her answer was very simple: "You can put a hundred hearts! Just refine the weapon according to the steps required by the formula, and finally when you carve the six-star magic circle, I will teach you the method, and you will definitely not make a mistake!"

Out of great trust in the Ring Spirit Ling'er, Du Long could only put aside the problem of the six-star magic circle for the time being, his biggest shortcoming was that the magic circle was on the same page, after all, it took a lot of time to immerse himself in it.

Du Long, who has grown to his current strength, has only spent more than forty years, and the most missing thing is time!

After continuing to make the steps of smelting various metal ores on the recipe clear, Du Long opened his eyes, glanced around, and stood beside the forge.

Turning over his hand, a swarthy iron hammer that he usually used to forge weapons in Qinglang Cave appeared on the forging table, and as for the rest, there was nothing else to prepare, and his left hand stretched out and pressed on the Sixiang Furnace off the fire opening.

Call!

Like alchemy, the refining process also needs to be carried out before the furnace is heated, and only after the furnace is heated in advance can it reach the best state, whether it is refining or alchemy, it can avoid making low-level mistakes!

After seeing Du Long put a big hammer that was calcining immortal soldiers on the calcining table, the old man of the fire secretly breathed a sigh of relief, the reason why he had prepared everything else, but only dropped the calcining hammer, was to see if this kid was a real refining craftsman, and he had the intention of temptation.

Seeing that he really skillfully took out a calcining hammer, he was relieved, if this kid couldn't even take out the most basic calcining hammer, it would be funny!

After the hot tripod was completed, Du Long began to throw pieces of metal ore into the tripod one after another, looking at his flowing technique, many people nodded secretly.

After the previous few unimaginable performances, no one dared to say that he was not in public this time, and he dared to talk nonsense after losing face twice in a row, and he was bound to be called a fool by others!

The process of smelting the metal ore and refining the impurities out of it is much easier than refining the liquid medicine in the immortal herbs, as long as you desperately scorch the ore with a high-temperature flame!

Du Long has deliberately left one or two of these metal ores that are not too resistant to high temperature outside the ding, that is, they are ready to be smelted later, and it will be relatively easy to smelt these metal ores!

Inside the Four Elephant Furnace, the flames were rushing and roaring, constantly scorching the few pieces of metal ore that had been separated at a terrifying high temperature, these metal ores were worthy of being a six-star level existence, and it was really time-consuming and laborious to smelt them!

Of course, a very important reason is that the flame intensity in Du Long's body has just reached the six-star level, and it will be a little difficult to refine metal ore of the same level!

If you let a Da Luo True Immortal-level existence smelt these ores with the Da Luo True Fire in your body, I'm afraid it only takes a few breaths to melt them into molten metal, right?!

Time passed, and when Xia Qinglian walked out of the sixteenth test room, Du Long had not yet completed the smelting of those six-star metal ores, among which seven or eight auxiliary metal ores had been melted one after another, but only one of the largest six-star grade main ingredient red gold ore had still not completely melted into liquid!

Xia Qinglian, who walked out of the test room, swept around and didn't find Du Long, so she saluted the two red and white elders who looked over, and then followed everyone's eyes to look at her sweetheart in the fifteenth test room.

After sweeping the immortal consciousness again, Xia Qinglian immediately found that he was actually refining in the Danmeng, and he probably guessed something in his heart, although he had just entered the state of emptiness during the recovery period, he also vaguely heard part of the conversation outside.

So, she didn't talk to anyone, just stood aside and quietly watched the Du Long refiner!

In the No. 1 test hall of Nuoda, all the test rooms were empty, and most of the people gathered in the hall to watch the figure in the No. 15 test room, which was being tested for refining weapons.

In addition to looking with their eyes, everyone also swept into the Four Elephants Furnace with their immortal sense, and carefully observed that the various ores in the furnace were scorched by the flames, and finally completely refined into a mass of molten metal!

At this point, the smelting work is not over, as with refining the elixir, removing the impurities in the molten metal is an extremely important step, Du Long continues to maintain a stable flame temperature, constantly smelting many molten metals, watching them continue to boil and bubble out the impurities to expel the impurities.

This has been going on for a long time, if it weren't for the help of a treasure like the Four Elephant Furnace, Du Long would have been in agony, right?!

Seeing that the impurities inside the various molten metals in the Sixiang furnace had been almost discharged, Du Long swept his right hand, and only then did he put the last two pieces of metal ore with a low melting point into the furnace fire, controlling the two flames to wrap it in!

Almost when there were no bubbles coming out of the other molten metals, the molten metals smelted by the last two pieces of metal ore were also turned into two pure molten metals under Du Long's key care!

At this point, the work of smelting the molten metal is finally completed, and then there will be technical work, alloys!

Alloy, requiring all kinds of molten metal to be synthesized in the corresponding proportion, in addition, the sequence of each molten metal into the alloy liquid can not be wrong, one wrong step, all the molten metal will be turned into a puddle of scrap copper and rotten iron, useless!

Therefore, the expression on Du Long's face was extremely solemn, after all, this was the first time he had refined an immortal soldier according to the six-star fire dragon slash formula, and he had never come into contact with this alloy method!

'Ling'er!There can't be the slightest mistake in the alloy ratio, calculating the proportion of molten metal should be your strength, I hope you can grasp the scale of the proportion for me!' Before starting the alloy, Du Long couldn't help but ask for help from the ring spirit Ling'er, and the ring spirit agreed on the spot.

Only then did he begin to control the clumps of molten metal, splitting up the more parts of them until the Ringing Spirit stopped after he had no objection to the size of each lump of molten metal.

Secretly relieved, Du Long knew that as long as Ring Ling Ling'er felt that there was no problem, it would definitely be the best proportion, because this was what she was best at!

The ratio is not wrong, which represents a big step in the direction of success, and then Dulong began to melt the various molten metals into the red gold liquor one by one according to the requirements of the formula, and soon, all the molten metals were combined into one!

Call!

The flames in the Sixiang furnace rose, constantly scorching the molten metal inside, Du Long carefully observed the state of the molten metal, and watched it gradually turn into a pure golden yellow from a somewhat mixed color at the beginning, which also represented the successful completion of the alloy step!

The next steps were relatively simple, Du Long began to control the deformation of this molten metal according to the style drawn on the fire dragon slash recipe, until it perfectly presented the style of the six-star fire dragon slash!

A fire dragon slash made of alloy liquid condensed appeared in front of everyone, and there was a faint orange-red flame on its surface, which was beautiful!

Many people who saw this scene, although their faces were also a little amazed, they still seemed to expect Du Long to be able to do this, and they were not too surprised.

After the successful condensation, the most important thing is to carve the formation, which is the most important step, and it is also the main root cause why the refining tool is said to be many times more difficult than the alchemy!

In front of everyone's eyes, Du Long did not immediately start to carve the formation pattern, but began to ask the ring spirit Ling'er for advice, he didn't know what the six-star formation was, and how to start with it!
