A top-grade spirit stone is equivalent to the aura of 10,000 low-grade spirit stones, but you want to exchange 10,000 low-grade spirit stones for a top-grade spirit stone, but you can't exchange it, it's like you exchange a bunch of cabbage for a thousand-year-old ginseng, but anyone who has no problem with their brains can't exchange it for you.

The best spirit stones are very rare, only some of them will have them in the hands of some Yuanying Ancestors, but they are not willing to use these spirit stones for cultivation, but they are used to supplement the spiritual energy when they have to use the fighting method, not to mention tens of thousands of pieces of such precious things, even if they want a piece of Ling Jiu Wine, it is difficult to get it back.

"If you don't have the best spirit stones, the hundreds of thousands of high-grade spirit stones are fine, and millions of middle-level spirit stones are okay, even if the low-level spirit stones are enough, it is too troublesome to absorb them one by one, just like eating melon seeds, it takes half a day's energy, and there is not much meat. The machine spirit said in disgust.

"You're still too hungry to eat, if you think it's hard, then wait for death!Anyway, you are completely scrapped, I can at least be reincarnated, it's good to be a fool, it's rare to be confused in life!" Ling Jiujiu said with a grin.

"Uh, ahem, then the low-level spirit stone! I'll make a little effort!" The machine spirit coughed twice more and said, Ling Jiujiu was its only hope now, although Ling Jiujiu's legs were too thin now, but it still had to hold on.

The fifteen hundred spirit stones that had just arrived and had not yet been covered with heat were just given to the machine spirit as melon seeds, and when the machine spirit was about to leave the space, the machine spirit also specially told Ling Jiujiu to hurry up and practice the casting, because at least to the level of a middle-level refiner could repair the space.

Ling Jiujiu gritted her teeth, her heart was dripping blood, she thought she had picked up a treasure, but she didn't expect that she had become a debt collector, and now her body is less than six years old, and she is saddled with hundreds of millions of low-grade spirit stones, how can this kind of thing be reasonable!

Ling Jiujiu has been very busy recently, except for cultivation, the rest of the time is spent studying refining weapons, the basic refining tools Ling Jiujiu has finally finished learning, and the next step is to go to the furnace to create spiritual weapons.

Refiners need a casting room to build spiritual weapons, and real refiners have their own casting rooms, but newcomers like Ling Jiujiu don't have this kind of treatment, so Ling Jiujiu can only rent the basic casting room in the sect to practice.

The casting room is open to people from the Casting Peak for free, but if you want Ling Jiujiu to be a person who is not from the Casting Peak, you can only spend spirit stones, of course, the price is not high, a spirit stone can be rented for half a month, and Ling Jiujiu spent two spirit stones and rented it for a month.

Ling Jiujiu is very poor, these two spirit stones are her own, and this little spirit stone is still something she pulled out from between the teeth of the machine spirit!

Female monks generally like to learn talismans, formations or alchemy as their auxiliary professions, and refining tools are rarely learned by female monks, after all, female cultivators want to be beautiful, and carrying a big hammer to strike iron really does not match the image of a fairy, and refining tools are the most difficult of all auxiliary professions to learn, so there are very few female cultivators who come to the casting room, and even fewer are young like Ling Jiujiu.

"Oh, Xiao Jiu, you're here again! you're really diligent, how is the casting practice going?" The disciple guarding the casting room greeted her with a smile when he saw Ling Jiu's wine.

"Alas, it's okay! Senior brother, I'll go in first, I'll give you the summons paper crane you want tomorrow and the day after tomorrow, and you can ask me again when it's used up!" Ling Jiujiu said.

"Oh, thank you for that!" The disciple guarding the door smiled even more after listening to Ling Jiujiu's words, and then he persuaded again, "Refining is already difficult to learn, it's normal for you to practice slowly, don't put too much pressure on yourself, it's not worth it if your body is tired!"

Cultivators who have not yet reached the Qi refining period are only a little stronger than mortals, and it is not good for a child with a long body like Ling Jiujiu to be tired and ruthless.

Ling Jiujiu also understands this truth, but she is pressed for time! The most important thing is that she is poor! After learning to cast a weapon, she can at least sell some spiritual weapons to make some money, now she needs money to cultivate, she needs money to buy materials, and there is a money-burning instrument spirit waiting for her to eat, she can't do it if she doesn't work hard!

Ling Jiujiu smiled, and then entered the casting room, she opened the valve of the earth fire with great skill, and then a golden flame came up from below.

"Just dust and sand, anti-bone wood, Ge Yunshi, brute vine," Ling Jiujiu took out the materials she needed, and then she counted them again, and after making sure that nothing was missing, she picked up the sledgehammer next to her.

What she wanted to practice was a basic flying sword, the lowest quality spiritual weapon, she had tried it once yesterday, but the result ended in failure. Ling Jiujiu only felt that her heart hurt and she couldn't breathe after seeing that pile of rags, these were not scrap iron, these were all her money!

Ling Jiujiu went back and studied the master's casting codex in the space, and in this codex, there was the master's refining experience when he first started, Ling Jiujiu read it carefully, and finally understood what he had done wrong.

Ling Jiujiu put in the same materials, every time he put it in, he had to wait for the materials to be completely refined before he put it into the next one, the importance of this step was specifically mentioned in the master's codex, if the impurities were not cleared, it would affect the quality of the refined spiritual weapon, and even lead to failure.

This is a very test of patience, because you have to concentrate on it, you can't be sloppy, Ling Jiujiu did it for two hours before he put all the materials in, and at this time all the materials in the furnace have turned into a silver liquid, the liquid is like flowing mercury, faintly with a flowing light.

Ling Jiujiu scooped a spoonful of spiritual spring water next to him and poured it in, and with a sound of "z", a burst of mist emerged after the spiritual spring water touched the material, and the material quickly turned from liquid to solid.

Ling Jiujiu took out the material with iron tongs and put it on the casting table, she laboriously picked up the hammer head, and smashed it into the iron with a hammer.

It didn't take long for Ling Jiujiu's arms to be numb, but Ling Jiujiu didn't rest, but let the sweat on her head run down her cheeks, she couldn't stop at this time, because if it stopped, this furnace would be in vain.

For five hours, Ling Jiujiu kept swinging the hammer and striking it, and the piece of iron gradually took shape in her hand, turning into the shape of a sword.

Step by step, Ling Jiujiu didn't dare to be negligent, and finally, after pouring another scoop of spiritual spring water, the sword shone brightly, and the sword was finally done.
