"I'm not in a hurry yet, you can't wait."

Fang Yi smiled and looked at Wei Mingcheng, reached out and picked up the glass bottle containing yellow liquid. When Fang Yi pulled out the bottle plug, a pungent smell of chemical potion immediately filled the noses of several people.

"What is this? Why does it smell so bad?"

Bai Chuxia covered her nose with her hands. After entering the innate world, they were particularly sensitive to smells and sounds. The sounds heard in the ears of ordinary people and the smells smelled in their noses came to them, which seemed to be magnifying many times under a magnifying glass.

"Early summer, you put on your mask."

Fang Yi took a pair of masks from the table and handed them to Bai Chuxia, and smiled and said, "The smell is still behind. I am immune to this smell. Whoever can't stand it will wear a mask. I'll ask them to send several pairs."

I had an experience of playing skunks in Wild Man Mountain. The general smell really couldn't smell Fang Yi. Even if the six consciousnesses are not closed, the smell in this glass bottle is nothing to Fang Yi.

"I'll wear a mask, too."

After hearing what Fang Yi said, Si Yuanjie obediently picked up a pair of masks and put them on. He has just entered the innate world and has not yet learned how to close the six consciousnesses. In just a short while, the pungent smell made Si Yuanjie a little dizzy.

"After becoming a cultivator, his resistance is not as good as that of an ordinary person."

Fang Yi smiled and shook his head, poured the yellow liquid from the glass bottle into the glass container. With a "swish", a yellow smoke emerged from the glass container, and the pungent smell became stronger and stronger.

"This, is this thing aquarius?"

Wei Mingcheng showed a strange look on his face. Although he didn't learn chemistry well, he learned some extremely harmful chemical knowledge when he was in the army, including a mention of Shui Royal.

Aqua regia is a very corrosive liquid that can be used to dissolve high-temperature alloy steel, steel, aluminum alloy, antimony, chromium and platinum group metals, etc. It can also be used to dissolve certain iron ore, phosphate rock, slag, antimony and selenium, nickel-chromium alloys, as well as sulfides of mercury, arsenic, cobalt and lead.

As ordinary people know about sulfuric acid, it is simply a slight witch in front of the rosaris and is not worth mentioning at all. For example, if a pig is thrown into the rosaris for a day, the pork will be corroded, but the pig skeleton still exists. But if a pig is thrown into the rosaris, even a pig's hair will not be seen in one day.

"Robus?"

Fang Yi looked up at Wei Mingcheng, shook his head and said, "This is not aquarium, it is a solution made by mixing aquarium and super acid. Its corrosion is a hundred times stronger than aquarium, and its acidity is billions of times that of aquarium. Almost nothing can resist its corrosion."

The reason why Fang Yi has not started refining tools for more than half a year is mainly because he is waiting for this solution. In order to create this super acid solution, Fang Yi spent a lot of money half a year ago to entrust a foreign chemical institution to specialize in developing super solution. It was not until a month ago that they took out this product.

According to the chemical organization, this super-strong solution is definitely the most domineering solution in the world that combines strong acids and strong corrosion. According to the experiments they have done, almost all known metals and ores have been defeated in front of this solution.

"So awesome?"

After hearing Fang Yi's explanation, Wei Mingcheng and others were all shocked. The eyes of looking at the liquid also had a look of fear. If this thing drops on the body, it would probably corrode the skin directly.

"Actually, the water regia you mentioned was invented by people in ancient times because of refining weapons." Fang Yi asked someone to use water regia to study super solution, which was a wonderful idea caused by the source of water regia.

When the water regia first appeared, Persian alchemists mixed hydrochloric acid and nitric acid together to dissolve metals and liquids that could be dissolved. They used water regia to refine many products that transcend the civilization at that time, and the secret recipe for water regia configuration was also passed down.

Fang Yi suspected that the ancient Persian alchemists were evolvers, and the items they refined were naturally not ordinary. Since the evolutionists used water regia to refine materials, Fang Yi believed that he would not be wrong in doing so.

"Fang Yi, look quickly, this piece of golden spirit seems to have been broken down."

Bai Chuxia, who had been staring at the glass container, suddenly exclaimed because she found that the originally small piece of gold essence had shrunk a circle at a speed visible to the naked eye under the corrosion of super acid, and obviously could not withstand this super acid.

"It's okay, this is the way I came up with to extract it."

Without Bai Chuxia's reminder, Fang Yi's spiritual sense has been paying attention to the situation in the container. The corrosion of the golden essence was something Fang Yi expected. The reason why he created this super solution was to make it corrode various refining materials in his hands.

Fang Yi thought that if you should make flying sword magic weapons, especially the natal flying sword, you must be perfect in the materials used, and you will not tolerate any mistakes. If the materials used to make flying swords can be easily corroded by super acid, then even if the flying sword is successfully refined, it will probably not be able to catch Fang Yi's magic eye.

Therefore, Fang Yi would rather all the materials on his hand be corroded than to make a flying sword just by himself.

However, as the golden essence further decreased, Fang Yi gradually became a little uneasy. After all, it would take tons of gold to be calculated by refining a little gold essence. If such a small piece of gold essence was converted into money, it would probably be at least more than 10 billion. Seeing that the golden essence was dissolved bit by bit, Fang Yi's heart was also bleeding.

An hour passed, and the golden spirit was still getting smaller. After two hours passed, the speed of realm dissolution began to slow down. After three hours passed, only Fang Yi could find out whether the golden spirit was still changing.

Five hours later, except for Fang Yi, the few people waiting next to him, including Bai Chuxia, became a little listless. I heard that Fang Yi was going to refine weapons before, but they thought it was a very exciting thing, but they didn't expect it to take half a day to decompose and refine a piece of material, so they stood there and waited. Everyone felt very bored.

"Fang Yi, is it almost done?" Wei Mingcheng stretched out his head and glanced into the container. At this time, the golden spirit was covered by a super solution. If he didn't need to observe his spiritual sense, he would not be able to see any clues.

"It should be fine. This golden spirit may have been refined to the extreme."

Fang Yi nodded. Only he knew that the piece of gold spirit, which was originally the size of a matchbox, became only as big as a thumbnail after five hours, and it had not changed for an hour.

The golden essence highly refined from gold actually has so many impurities, which shocked Fang Yi and was extremely happy, because the essence that was left behind by eliminating the dregs must be. And so many golden essences with thumbnails are enough for Fang Yi to refine a flying sword.

"Wuliang Tianzun, where did you find so much gold to extract in ancient times?"

Looking at the golden essence the size of a thumbnail, Fang Yi couldn't help but complain that the gold used by the alchemy of gold can make people become a wealthy place. It seems that the saying "poor literature and wealthy martial arts" passed down in ancient times can also be applied to practitioners.

However, what Fang Yi didn't know was that the core of each gold ore vein was a high-purity gold essence, and the entire mineral vein was derived from the gold essence. When ancient Qi Refiners were looking for the gold essence, they didn't need to extract it from the gold. They just needed to take the core away.

Without the gold ore veins in the core of the mine, the quality of the gold ore will gradually decline over time, and then evolve into other minerals. It may also be nourished by the spiritual energy of heaven and earth, and the gold ore veins will produce gold essence again, which is also called the refining material in the eyes of Qi Refiners.

It was in the current Dharma-Ending Age that all things in the world no longer had the nourishment of spiritual energy, and gradually transformed into mortal objects. Now the gold ore veins on the earth are all ordinary ore veins after the disappearance of the golden essence under the erosion of a long time.

"A job has been completed." Fang Yi poured the super solution in the glass container into another glass container, then used his spiritual sense to remove the small piece of golden essence and took it to his eyes and observed it.

Under the super corrosion and the uninterrupted dissolution of strong acids, the golden essence that has become much smaller has become more and more dazzling. The surface of the golden essence is shining with radiance, and there seems to be a series of charms flashing. Even Wei Mingcheng and others beside them can sense the spiritual energy contained in this golden essence.

"It's really different, but the process is a bit long." Feeling the changes of the golden spirit, Wei Mingcheng and others were all excited, but the decomposition and refining time was too long, and the mystery of refining the weapon had gradually faded in their hearts.

"The process of this high-tech weapon refining method is already very fast." Fang Yi couldn't help laughing when he heard Wei Mingcheng's words. If they knew how the ancient heritage refined weapons, they wouldn't have thought that five hours would have been a long time.

Not to mention the high-level Qi Refiners above the Foundation Establishment Stage among the ancient Qi Refiners. His true fire essence is pure and powerful. It takes a very fast time to purify ordinary materials. For example, the most commonly used materials such as the Golden Essence, the Qi Refiners in the Foundation Establishment Stage can quickly burn it out with the True Fire, and at most half an hour is enough.

However, if it is a low-level evolver, that is, a Qi Refiner who has just reached the Qi Refining Stage who uses the True Fire cultivation, it will take several times more than five hours to refine the golden essence.

You should know that the true fire emitted by the Qi Refiner needs to be supported by his own cultivation, and it consumes a lot of money on the spiritual energy in his body. After releasing for ten minutes, it will almost be consumed. At this time, they can only stop refining and then practice meditation to restore the spiritual energy. After repeated cycles, it often takes four or five days to purify a piece of golden essence.

For low-level Qi Refiners, this cannot be considered a bad thing, because the entire process of refining weapons is also a process of cultivation. Although it is very likely that it will take several months or even adulthood to refine a magic weapon, after the refining weapons is completed, their cultivation has also improved unknowingly.

Refining weapons is not only a terrazzo skill for low-level qi refiners, but also for high-level qi refiners.

Because gold essence can only be considered a relatively ordinary material among refining materials, and some special materials are purified by high-level qi refiners, and the consumption is also huge. They also need to practice while refining weapons. Behind the birth of a magic weapon is the huge effort put in by the qi refiners.

As for spiritual weapons, it is even more difficult to refine. Only the master-level weapon refiners in ancient times can refine spiritual weapons. The failure rate is very high and the effort consumed is unimaginable. In addition to having a suitable spiritual body, this is also one of the reasons for the scarcity of spiritual weapons.
