"You know I don't have a crystal." Zuo Mo said with a hard head.

  "Hmm, you can owe me. This time I spent two of my fourth-grade crystal stones. Hmm, plus my fee, considering we're all familiar with each other, let's give a discount, just eight fourth-grade crystal stones in total, ten fourth-grade crystal stones. Hmm, pay it back within three months, if it exceeds one month, double the amount."

  Zuo Mo's hands and feet felt cold: "Pu, this price is also too outrageous..."

  "Oh no, no, no! I'm a heavenly demon, and my appearance fee is very expensive!" said Pu Yao with shamelessness.

  Ten pieces of four-star crystal stone are equivalent to five thousand pieces of three-star crystal stone... Three months...

  Zuo Mo felt a wave of dizziness and he made one final effort: "This is impossible!"

  "Hmm, no problem, I like interest!" The Pú Yāo revealed a charming smile.

  Dong Fu, Zuo Mo sat in the store, fully focused on controlling the clockwork fire. In that white flame, only a crystal clear liquid bead was rolling and changing. A cultivator stood aside, not daring to breathe, staring at the milky white flame with extreme tension.

  Suddenly, the Zhong Sun fire dissipated, and a transparent and clear medicinal liquid floated quietly in front of Zuo Mo. The air was instantly filled with a strange fragrance. With a familiar motion, Zuo Mo guided the medicinal liquid into a jade bottle that had been prepared long ago. As soon as the liquid entered the bottle, he immediately sealed it with a stopper.

  "Your Bellflower Extract, twenty Three-Product Crystal Stones." Zuo Mo said expressionlessly.

  "Brother, can't you give me a discount? This is my ninth time coming to your place!" The cultivator asked with a pleading face.

  Zuo Mo raised his expressionless face: "My appearance fee is very expensive."

  The other party was speechless, and could only reluctantly and painfully take out twenty third-grade crystal stones. Zuo Mo didn't even look at them, directly putting them into his waist pouch, then closed his eyes, crossed his legs to recover his spiritual energy. After a while, he opened his eyes: "Next one."

  Li Yingfeng hastily let someone in. Ever since Zuo Mo came to this shop, the business has been so good that it surprised her greatly. She didn't know where Zuo Mo's younger brother got a strange white flame from, which was extremely cold. Zuo Mo's younger brother also showed off his business skills. He almost took on all sorts of unusual and bizarre businesses, such as refining and purifying medicinal liquids, or smelting certain raw materials. These unheard-of businesses were all provided by Zuo Mo's younger brother.

  But she soon discovered that Zuo Mo's younger brother only provided intermediate services such as purification and refinement. He didn't even provide services like alchemy, which had left her baffled - wasn't his younger brother best at alchemy?! It was only later that she understood the subtlety behind it: efficiency. Only refining half-finished products, combined with Zuo Mo's terrifying spiritual power recovery ability, resulted in an extremely astonishing efficiency.

  He was like a human-shaped stove, tireless.

  Compared to this, her junior brother's terrifying flame control didn't surprise her too much!

  Until now, Zuo Mo's junior apprentice had not made a single mistake. This point left Li Ying Feng in awe, but it wasn't strange. Zuo Mo's junior apprentice was a genius at refining dan, and being skilled at controlling fire was only natural. It was his terrifying success rate that quickly made him famous in Dong Fu. Everyone knew that in the No Empty Shop of Dong Fu, there was a zombie-like guy who controlled fire with an otherworldly skill, and also had extremely rare white cold fire. Although the grade of that white cold fire wasn't high, it was very formidable, and the semi-finished products made from it were all of excellent quality.

  Originally, Cold Fire was hard to find, and there were few cultivators who possessed it. Generally, those with fire attributes were either skilled at refining equipment or refining elixirs and food, so who would be willing to process intermediate goods? Suddenly, a cultivator appeared who was willing to process intermediate goods, and the cultivators who needed them swarmed over immediately.

  He was wearing a bamboo hat and when he saw Zuo Mo, his footsteps slightly paused.

  "What is it that you want to refine?" Zuo Mo asked without lifting his head.

  "The four cold magnetic irons." he said.

  Zuo Mo was slightly surprised and raised his head to look at the other party. He shook his head: "I can only refine third-grade products, fourth-grade is beyond my ability, please ask someone else."

  Zhong Sun Huo is only a second-rate fire seed, if not for his strong spiritual awareness and greatly increased control over fire, he could only refine second-rate items. Even so, third-rate is currently the limit of Zuo Mo's abilities, as for fourth-rate Glacial Magnetic Iron, it's not even worth thinking about.

  "The other party hesitated and said: 'Can you cut this fourth-grade cold iron into four pieces?'"

  Cut off? Zuo Mo thought for a moment and said: "Can try."

  The other party took out a black stone with blue ice chips mixed in it and handed it to Zuo Mo.

  Zuo Mo didn't hesitate: "Two hundred top-grade spirit stones as payment."

  "Good." The other party replied readily.

  Rich people! Zuo Mo's heart was filled with indignation and disdain, but his hands quickly took the fourth-grade Cold Magnetic Iron.

  He thought of refining semi-finished products, all because of the pressure from Jing Shi. After shouldering a debt of 5,000 three-product crystal stones, Zuo Mo had no choice but to rack his brains to think of ways to make crystal stones. Planting Red Flame Grass was not a bad way to make money, but it meant he needed to rent five spirit gardens the size of the previous one. What made him feel helpless was that even if he used all his spiritual plant cultivation techniques, the growth cycle of Red Flame Grass would not be less than five months!

  He didn't hesitate to rule out this plan. In just over a month, it would double, and in five months, it would mean that he wouldn't need to repay 20,000 third-grade spirit stones!

  Helpless, he could only pin his hopes on Zhong Chuihuo.

  It's unrealistic to expect to earn 5,000 third-grade crystal stones in three months by refining elixirs. As for equipment refinement, even if he starts learning now, it will be too late. Suddenly, an idea struck him and he thought of processing semi-finished products. He was already very familiar with the purification and refinement of spiritual herbs, and some equipment refinement techniques were not complicated to learn either.

  Zhōng sǔn huǒ hǎo dàishì xī yǒu hán huǒ, yóu qí shì hé liàn zhì yī xiē yīn hán shǔ xìng de líng cǎo hé cái liào. Yōng yǒu huǒ zhǒng de xiū zhě běn jiù shǎo dé kě lián, yōng yǒu hán huǒ de rén jiù gèng shǎo le, ér yuàn yì jiā gōng bàn chéng pǐn de rén jiù zuǒ mò yī gè!

  This business wasn't very profitable to begin with, after all it was only half-finished products and they could only collect some processing fees. But after getting the demon core, Zuo Mo's control over fire suddenly skyrocketed, and the flames in his hands seemed to come alive, the efficiency of refining things was extremely astonishing. And with the addition of magic seals, his spiritual power recovery ability became incredibly powerful, he only needed to meditate for a short while before his spiritual power was fully restored.

  Due to the unresolved issue of storing spiritual energy, although his current speed of absorbing spiritual energy has increased and the effect of refining his body is significant, his cultivation progress remains quite limited. Because of this problem, he went to discuss with Pu Yao many times. The actual effect of the magic tattoo was far from what Pu Yao had advertised earlier, so Zuo Mo demanded a partial waiver of his debt.

  In the face of reality, Pu Yao could only admit this and reduced Zuo Mo's debt of one thousand third-grade crystal stones.

  The debt of 4,000 three-product crystal stones made Zuo Mo let out a slight breath of relief, and he soon discovered the most effective way to use the magic tattoo. Since its effect was to increase the speed of spiritual energy absorption, then quickly using up the spiritual energy and quickly replenishing it would work, wouldn't it?

  He soon discovered that adding the demon core to the clockwork fire and matching it with semi-finished products was a perfect match!

  Apart from the first few days of average business, the later business was extremely hot, as many cultivators poured in to participate in the Dongfu Sword Trial Conference. Zuomo's processing fees were not cheap, basically starting at 20 three-product crystal stones, and when encountering something slightly better, it immediately jumped to 40 three-product crystal stones.

  Like just now, shouting two hundred Sanpin crystals is simply a lion's big mouth, but I didn't expect the other party to agree without hesitation.

  According to his usual harvest, he can earn about 200 third-grade crystal stones per day on average. At this rate, he will be able to pay off his debts soon. However, for this kind of business, timing is also crucial. If it weren't for the fact that he coincidentally caught up with the Dongfu Sword Trial, relying solely on the local cultivators in Dongfu, having 30 or 40 third-grade crystal stones per day would be quite good.

  But such crazy refining and processing has yielded rich rewards for him.

  For example, he figured out that arranging the clockwork fire into a three-turn fire array can greatly enhance the fire effect and even refine some four-grade spiritual grass. However, generally speaking, refining materials like four-grade ones is something he never takes lightly. Mainly because the risk is too great, if he accidentally ruins someone else's material, he won't be able to afford it himself.

  The prices of these four products are quite outrageous.

  This time the other party's requirement was only to cut off the cold iron, and Mo thought that the risk was not great. Moreover, the two hundred third-grade crystal stones offered by the other party did not even haggle over the price, and he also felt that the profit was substantial.

  If we say sharp, nothing is sharper than a flying sword. However, some materials cannot be cut with a flying sword because it will damage their properties, and ferrite is one of them. Cutting ferrite is quite particular, as the distribution of its magnetic body is not uniform, and ensuring the integrity of each piece of magnetism to the greatest extent is a very complicated matter.

  But for Zuo Mo, it wasn't that difficult. The yao core was practically born for the "Fetal Breathing Spiritual Cultivation" and his current spiritual sense progress was so fast that even he felt shocked and frightened. After his spiritual sense became strong, inspecting third-grade materials almost didn't require any effort, fourth-grade materials weren't as easy, but if he used those spiritual sense threads, he could quickly finish the inspection. His spiritual sense not only strengthened his control over fire, it also allowed him to have a deep understanding of the materials, to be able to calculate them in his mind, and to refine them with twice the efficiency, the effect was astonishing.

  It took nearly two hundred three-star crystals and a great deal of care from Mo, and each time he worked with four-star materials was a rare experience.

  He closed his eyes and used his spiritual sense to explore the small piece of lodestone with his hands several times, until he was completely sure of its magnetic distribution, before opening his eyes.

  The guest wearing a black veil and a bamboo hat only saw Zuo Mo holding the Cold Ice Iron, closing his eyes to cultivate for a long time, suddenly opening his eyes.

  The left hand held a cold iron magnet that slowly flew into the air, and at the same time, a white flame appeared quietly, with a strong cold air around.

  A flicker of astonishment flashed across her eyes behind the veil.

  Zuo Mo sat as usual, his face still expressionless, but those eyes could make people feel his full attention and seriousness.

  The two hands in front of his chest suddenly moved and changed continuously, bringing up a string of phantoms.

  The floating clockwork turned into a very fine white flame line, like a small white snake winding around the cold magnet.

  Suddenly, the moving fire line speeded up sharply, and the black-veiled guest only felt a white light in front of him like electricity, turning and winding, head and tail connected!

  Three Turns of Flame Formation, Suddenly Takes Shape!
