Bu Qin carefully flipped through the "Purple Jade Ancient Jane" several times, and wrote down in detail the alchemy techniques required for each Yuan Shen magic weapon of the Great Five Elements Sword of the Sichuan Dynasty.

In the Immortal Cultivation Realm of Middle-earth and the East China Sea, the Five Elements Alchemy is the most basic alchemy.

Different types of Five Elements raw materials often need to be refined using the Five Elements Alchemy Technique in order to refine the Five Elements Magic Weapon.

Among the various refining techniques, the most common are the two major refining systems of fire alchemy and water alchemy.

Fire alchemy is mainly used to refine "gold, stone, mud, sand" and other ore-based raw materials such as gold, earth and fire, remove the dregs in the ore, and refine them into gold, fire and earth magic weapons.

Water-based alchemy is mainly used to refine non-ore raw materials such as "silk, wood, correction, flower, rattan, and liquid" and other wood-based and water-based raw materials, remove the dregs in non-ore raw materials, and refine them into wood-based and water-based magic tools.

Of course, it is not absolutely possible to say that there is a certain raw material. The same refining technique must be used.

Because gold and earth are raw materials, you can use water for alchemy. Wood-based raw materials can also be used for fire alchemy. It's just that the magic weapons refined by different alchemy techniques. The performance is very different in all aspects, and the use is also different.

In addition, there are three types of alchemy: gold alchemy, earth alchemy, and wood alchemy. It is rare, and few monks study these kinds of alchemy.

Tu Lux is good at gold earth alchemy. Most of the blades they refined were either refined with gold and earth alchemy. Use divine power to violently impact gold and earth ores with each other, and after thousands of tempering, they remove the dregs and become extremely tough blades, and the killing power is no less than that of monks.

The alchemy techniques of the three systems of wind, ice, and thunder are even rarer, and only a very small number of refining cultivators with these three spiritual roots can master them.

Not only refining weapons, but also alchemist alchemy has both fire-based alchemy and water-based alchemy, etc., with a variety of completely different alchemy techniques. Fire alchemy pill, the elixir refined, is often warm. Water alchemy, the elixir refined, is often cold.

And the raw materials that are separated from the five elements, such as "the wings, bones, claws, and fur of demon beasts", must be refined with yin fire and refined into special ghost weapons.

The Bat King Wing Spirit Weapon that Ye Qin had possessed a long time ago was made from Yin Fire. And the Jindan Skeleton Demon that he later refined with his own hands was refined by the bone alchemy of the Yin Xuanmen. There are very few ghost weapons in the immortal cultivation world, and a big reason is that very few monks can control yin fire and are proficient in bone alchemy.

In addition, there are some rare raw materials, such as "Mithril, Mithril", "Mithril", etc., and the refining technique is extremely rare, and it is often an exclusive secret technique. It can be said that the alchemy techniques in the immortal cultivation world are strange and all-encompassing.

In the Purple Jade Ancient Jane, the method of refining the "Tianyi Youshui Sword" recorded is an alchemy technique called "Water and Fire Mixed Defeat Technique".

This kind of alchemy is not a relatively rare alchemy technique in the immortal cultivation world, and few monks will learn this kind of remote refining technique.

It is recorded in the ancient manuscripts of purple jade that several auxiliary materials are also needed for refining, among which "Mosong Charcoal and Qiong Whale Liquid" are the most precious and rare.

Ye Qin knew very little about alchemy, so he could only draw a scoop based on the gourd, and follow the cutting records in the "Purple Jade Ancient Jane" to do it step by step.

First go and prepare all the main refining materials and minor auxiliary refining materials, and then refine the equipment.

The raw materials of the two flavors of the main refiner are Tianyi Youshui and the water system elemental essence.

Tianyi Youshui is enough, but only the water system is lacking.

Ye Qin is in the coral forest at the bottom of the sea. The one that was not damaged and intact was the seventh-order ghost demon shrimp demon pill that happened to use the Yuan Essence to refine the secret technique. It took him several days to refine the essence of the demon pill.

The main refining materials were all available, and Ye Qin began to collect auxiliary refining materials.

Although Waterfront Castle has many rare raw materials. They were all those Jindan monks and Yuanying monks who went to the Scarlet Sea to adventure. Brought back from the Sea of Blood. The amount of raw materials here is sufficient, and the price is cheaper than that of Xianque City and Baifu City.

Ye Qin didn't need to go to other East China Sea Immortal Cities to look for materials, he only spent two days in the Fang Market, street stalls, and chamber of commerce pavilions in Linhai City, and found the raw materials for several flavors of auxiliary refining tools he needed, including Ten Thousand Years of Ink Pine Charcoal and Seventh-grade Qiong Whale Liquid.

Refining Tianyi Youshui Scraping requires at least a thousand pieces of high-quality Mosong Charcoal and a thousand drops of seventh-grade Qiong Whale Liquid.

It is said that this spirit tree can only grow on a very small number of islands in the East China Sea, and it must be more than 10,000 years old.

Take its wood, burn it with samadhi real fire, and refine it into black pine charcoal in three days. Such a small piece of about three inches long and wide 10,000-year-old Mosong Concubine is worth more than ten medium-grade spirit stones.

And the Qiong whale liquid, it is necessary to hunt the Jindan-level Qiong whale sea beast and torture it with cream to get this liquid. Whales haunt the depths of the sea, and the higher the level of the whale, the better the quality of the whale fluid. A drop of seventh-grade Qiong whale liquid is worth six or seven medium-grade spirit stones.

Such an expensive price, the required quantity. made Ye Qin speechless

For the Jindan monks, it was very difficult to prepare the auxiliary refining materials needed to refine a Yuan Shen magic weapon. And the best main material is even more accessible but not sought.

Ye Qin didn't have many spirit stones with him, so he could only refine the pill, exchange them for spirit stones, and then buy the materials for these refining weapons.

Fortunately, his grandmaster-level alchemy can already refine the eighth-order and ninth-order elixirs, and the price of such high-level elixirs in Linhai Chengfang Market is also outrageously high, which is very tight, and he does not worry about sales, which makes it easier for him to make money.

In Linhai City, Ye Qinguang exchanged alchemy for spirit stones, which were used to buy various raw materials for refining, and it took more than half a month of work.

All the raw materials were prepared, and Ye Qin entered the refining room of the other courtyard and retreated to refine the weapons.

There are many Yuanying monks in Linhai City, and there are patrol guards composed of Jindan monks to maintain order. Outside the courtyard rented by Ye Qin, there were also Jindan-level monks guarding it, and no one dared to make trouble in Linhai City. Don't worry about safety.

Ye Qin suppressed the joy in his heart, hurriedly entered the empty and spacious refining room on the four walls, closed the heavy door of the stone room, and laid down a defensive formation with a formation flag.

Then he sat cross-legged and took the silver armor guard along with the Tianyi Youshui, the Yuan Jing of the Ghost Demon Shrimp, the Mo Song Charcoal, the Qiong Whale Liquid and other things in its belly.

There were also some bottles and jars, such as the Bigu Pill in retreat, the spirit wine that replenished mana, and the small silver bottles with Mithril added to them, all of which were taken out of the storage bag.

"This is the last Yuan Shen magic weapon missing from the Great Five Elements Sword Formation. Once this sword is refined, it can form a large five-element sword array, and the five swords are one. The Purple Sword Divine Monarch boasted in "Purple Jade Ancient Jane" that the Great Five Elements Sword Formation he had researched was invincible during the Jindan period. I don't know if it's true?".

Ye Qin looked excited.

"It doesn't matter if the Purple Sword Divine Monarch is boasting or not. There is no doubt about the great power of this Great Five Elements Sword Formation! Next time, it will be besieged by several Jindan monks at the same time. There is no need to be afraid at all. ”

He quickly gathered his mind and focused his attention on the refining weapon.

"Whoosh!"

Ye Qin slapped with his right hand, and a mana was struck. In the belly of the silver armor guard, a drop of Tianyi dark water was immediately ingested in the air and floated a foot in front of him.

This drop of heavenly water, only the faint black color of the water droplets, seemed to be absorbing all the light emitted, and it also emitted a faint aura of silence, rapidly consuming the mana that Ye Qin had played. Erode mana.

In just a short period of time, Ye Qin felt a little struggling, and he needed to keep playing mana to keep it suspended in mid-air. In a few hours, the mana in his body will be depleted.

Although Ye Qin was already familiar with its situation, he still couldn't help but feel frightened at this time.

With his current cultivation at the first level of the Jindan stage, he can control a high-level flying sword, and he can fly continuously for a month without stopping. If you drink spirit wine halfway to replenish mana, it will not be a problem to fly for a year and a half.

And at the same time, he controlled the four Yuan Shen magic weapons, namely the Nanming Lihuo Sword, the Golden Crow Yao Light Sword, the Tianqi Silk Sound Sword, and the Huangtian Houchen Sword, and if he fought the method, it would be able to last for about an hour.

However, manipulating this small drop of sky and water can only last for a few hours. A look of worry appeared on Ye Qin's face.

Even if the Tianyi Youshui Sword is refined, I really don't know how strong and terrifying mana it needs to drive this sword!

If you use all your mana. I can't drive this Tianyi Water Sword, I'm afraid that this last Feili refining will not be able to use it myself. It's similar to the Red Jiao Sword and the Xunlei Ancient Mirror, which must consume vitality before it can be driven.

"No matter what, let's refine it first! Since the Purple Sword Divine Monarch said that once the Great Five Elements Sword Formation is refined, it will be refined. The Jindan period swept invincible, so the Jindan period monk will definitely be able to use this sword!"

Ye Qin muttered a few words to himself.

No longer worrying so much, and then, he made a move with his left hand. A three-inch-long piece of ink pine charcoal placed on the ground was suspended in the air.

Tianyi Youshui, Mosong Charcoal, the two together. But it's not compatible.

Under the forcible squeeze of mana, that drop of heavenly water gradually seeped into a piece of ink pine charcoal.

At this time, Ye Qin ingested a drop of Qiong whale liquid in the air and flicked his middle finger.

That drop of amber-colored Qiong whale fluid cut an arc in mid-air, quickly enveloping the black pine charcoal. Immediately after, a small ball of samadhi true fire was formed, igniting the Qiong whale liquid and Mo Song charcoal at the same time.

"Bang!"

Mo Songchar immediately burned violently, and that drop of Qiong whale liquid added fuel to the fire, and its flames were even more fierce than the true fire of Samadhi. And this fire is more persistent. The entire refining room. It's like being in the midst of underground lava.

In the mixture of fire and water, that drop of water began to vaporize.

The flame burned a pillar of incense before it was extinguished. Mo Songchar and Qiong whale liquid were burned together and disappeared completely.

In the blazing heat, most of the water in Tianyi was completely turned into mist, and disappeared in the air, leaving only a trace of water thinner than a hair, which could not be refined, and was still suspended in the half banquet, its luster was more dark and deep, and Kuibao was as bright and dazzling as Kuibao.
