……

After Luo Mubai and the old man of Tianlei Gate reached a deal, they gave each other two bulging storage bags.

There are forty Zhuji Dan in it, hundreds of bottles of pills to enhance cultivation, thousands of spirit stones, and more importantly, there is also a 'Dust Reduction Pill' that increases the probability of knotting the golden pill, with these pills, even if the old man takes it to cultivate, there is a certain chance of condensing the golden pill.

Roughly estimated, the total value is more than seventy or eighty thousand spirit stones, which is definitely more than what was exchanged in Miaoyinmen seventy years later.

The old man of Tianlei Gate took the storage bag crampedly and checked it with his divine sense, and was immediately shocked.

This deal can't be said to have failed, the Heavenly Thunder Sect spent thousands of years in order to cultivate the Golden Thunder Bamboo, and the manpower and material resources were consumed a lot, but unfortunately it was useless at all, and he couldn't wait for the time when he could successfully cultivate the Golden Thunder Bamboo, and now it was the most correct choice to exchange it for a chance for the sect to rise.

The old man was not confused, if he refused, even if the Jindan monk in front of him would not embarrass him, the Heavenly Thunder Sect would definitely not survive for long!

As for Luo Mubai, he stepped forward and collected the delicate pure white golden thunder bamboo, cleaned up the spiritual soil, and put it in a special jade box, which was finally made into the materials for refining a set of magic weapons.

Subsequently, he didn't want to stay longer, and under the complicated eyes of the old man of the Heavenly Thunder Gate, he turned into a long rainbow and left the island, heading straight to Tianxing City, just preparing to open the furnace to refine the magic weapon.

……

Half a month later, Luo Mu returned to the cave on the spiritual vein of the holy mountain of Tianxing City, and after finding that everything was fine, he fed some demon beast blood in the spirit beast room for the blue scale python to eat, and left after a while.

He entered the secret room and arranged several sets of formations, and after a few days of adjusting his breath, his spirit and spirit returned to the best state, and he browsed the refining method of the 'Four Immortal Sword Formation' in the jade slip, studied and scrutinized it many times, and carefully visualized the refining method, in order to increase the quality of the magic weapon in the refining process.

Then, he took out a quaint furnace and an astonishing amount of refining materials from the storage bag, which contained strange-shaped beast bones and horns, most of which were sixth- and seventh-order demon beast materials that were killed at sea, as well as ores of different colors, crystal spiritual objects, and several top-level materials such as golden thunder bamboo.

After arranging and classifying all the refining materials in order on both sides of the body, he opened the furnace refining by himself.

"Whew"

Luo Mubai took a long breath with a calm expression, and the mana in his whole body began to mobilize, and then he opened his mouth and sprayed, and a wrist-thick cyan flame shot out of his mouth, directly spraying under the ancient Ding Furnace, a cyan flame was boiling and burning, so that the Ding Furnace began to warm up, which was the natal pill fire that only had cultivation in the Jindan period.

However, all Jindan monks or Yuanying monks, refining weapons, alchemy, and refining spiritual objects, etc., will choose the natal pill fire and the Yuanying true fire, because although the temperature of this flame is not as fierce as the supernatural flame, it is extremely stable, and it will not cause operation errors due to uneven temperatures, and waste many materials in vain.

Seeing this, Luo Mubai played a few tricks, and when he bent his fingers, he saw a burst of slender silky light hitting the cyan pill fire, but it was using mana to fix the natal pill fire, and convey mana, constantly burning the ancient Ding furnace.

It was not the first time he had refined a weapon, and after seeing the clouds and mist rising in the Ding Furnace, he knew that he could put refining materials.

This time, it was the "Four Immortal Sword Array" that was refined, which belonged to four magic weapons, and the difficulty was even more difficult than refining one magic weapon alone.

You must know that Luo Mubai is a magic weapon for refining the four non-attributes, and the properties of the materials required are different, and the properties of the refining materials are divided into four parts: ice, fire, wind, and thunder, and the auxiliary materials of the four attributes are first refined with the Ding furnace to extract the impurities and other minerals in the Ding furnace, so as to reach the level of purity of a single attribute, and after preservation, you can proceed to the next step of refining.

However, the refining materials are extremely consuming of spirit and mana, and they also need extremely precise divine consciousness to operate and control in order to refine the characteristics of many refining materials.

No, Luo Mubai put the fire chalcedony cloud crystal, fire crystal, purple lazuli, fire stone and other excellent fire attribute refining materials into the Ding furnace, and the glow of his right hand flowed, prompting the mana to make the cyan Dan fire more vigorous.

A day later, with a "snort", Luo Mubai solemnly pinched a trick, and the front furnace instantly erupted hundreds of rays of light of different colors, which turned out to be a liquid made of refining materials.

Luo Mubai's eyes were sharp, and he saw that those liquid materials seemed to be solidifying again when they came out of the Ding Furnace, and at that moment, he used some kind of magic in his hand to shoot at various liquid materials, wrapping them with mana to prevent them from solidifying.

You can't just destroy what you have spent your energy refining!

Subsequently, he divided these preliminarily refined substances into the prepared magic cover, took a few pills to replenish mana, and continued to put the ice attribute refining materials.

After the main materials of the Ten Thousand Years Cold Iron, Water Spirit Rhino Teeth, Xuanjing, and Cryocelian Stone Mines were refined separately, a large number of auxiliary materials were put in, and they were not collected one by one until they were also refined into liquid substances in one day.

Wind attribute materials are quite special, but Luo Mubai also got a top-level material, such as amethyst mica, water spirit rhino horn, and wind yao stone and other different refining materials, they themselves are very strong, and the refining time is long, but fortunately, it took a certain amount of effort to refine successfully.

As for the final thunder attribute materials, they are mainly based on the 10,000-year-old Golden Thunder Bamboo and the Thunder Crystal Divine Sand, the latter is also a rare top-level material, and the 'Blood Evil Divine Sand' and the 'Red Flame Divine Sand' are known as the three great treasures in the immortal cultivation world, and the magic weapon refined by the Legend Thunder Crystal Divine Sand can give off a trace of 'Zixiao Divine Thunder', and the effect is not worse than the Golden Thunder Bamboo 'Evil God Thunder', but the required quantity and weight are definitely not low.

Luo Mubai was also lucky enough to get three grains of rice-sized Thunder Crystal Divine Sand from a large auction in Tianxing City, this weight was like chicken ribs to Jindan Monk and Yuanying Monk, and when he learned that it was useless, he finally cheapened him.

At this time, he put four full four bamboo several feet long, pure gold-like into the Ding furnace and began to urge the natal pill fire to refine, although the golden thunder bamboo has a counterattack effect, but it is useless in the Ding furnace, directly use the natal pill fire to grind the golden thunder bamboo little by little, and after two days, it was finally refined into a large bowl of liquid substance.

The rest is the Thunder Crystal Divine Sand, it is a kind of crystal polyhedral sand, even a grain of Thunder Crystal Divine Sand is very strong, legend has it that ancient monks usually collect a large number of Thunder Crystal Divine Sand to refine a gourd magic weapon, and when attacking, you can summon Thunder Crystal Divine Sand to trap the enemy for refining.

Luo Mubai directly threw out a pound of thunder crystal divine sand, put it into the ding furnace and began to refine, the cyan pill fire was in vain, after three days of non-stop calcination, the entire piece of thunder crystal divine sand had melted into a round purple liquid, without impurities, and the liquid was also wrapped with a trace of purple thunder solitude.

At this time, the materials for refining are basically completed, and then the second step of refining is carried out, where all the materials are smelted together separately and the magic weapon is shaped.

Luo Mubai took out a few pills and took them, the previous refining step had taken eight days, if it weren't for the fact that he was not an ordinary cultivator, the spiritual consumption would definitely not be able to bear it.

After resting for a while, and feeling his spirit recover a little, he spewed out four mouthfuls of natal pill fire, suspended in the air and fixed it with mana.

Only then did Luo Mubai take out a few main materials, the fire marrow cloud crystal, the ten thousand year cold iron, the demon beast unicorn, the golden thunder bamboo, and the thunder crystal divine sand into the natal pill fire, and without hesitation, put the auxiliary materials that had already been refined into them separately, and let them smelt together little by little.
