The shopkeeper Fang saw that all the colors of the nine-star iron on the counter were dull, and it was obvious that it had not been polished by the sand chips, and it was an unpolished material, which was extremely unsightly. Suddenly, an old face pulled down, stood up and slapped it on the counter with a "bang", glared at Yin Zhaoping and scolded angrily: "How did you do it? These star irons are not polished, you dare to sell them!"

Yin Zhaoping heard the reprimand of the shopkeeper Fang, glanced at the pile of unpolished Xingchen iron, his face became ugly, and he hurriedly apologized to the shopkeeper with a smile, and then turned his head to stare at his son Yin Lan, and shouted: "Stinky boy, you did a good thing! I asked you to polish this morning, what did you do for Lao Tzu?"

I heard that for a period of time, the price of refining materials will rise, and Yin Zhaoping also hopes that after this batch of nine-star iron is sold, he will stock up on some more popular materials and make a small profit when the price rises. I didn't expect my son, who is usually diligent in his work, to not polish the nine-star iron this time, so that the price per kilogram of nine-star iron will definitely be lowered by the stingy shopkeeper Fang.

That's not all, if you make the shopkeeper feel that he is not honest and will not accept the materials processed by himself in the future, it will be troublesome!

Yin Lan had already expected this situation, and covered one of his ears to prevent his eardrum from being injured by his father's lion roar, and then said to the other party's shopkeeper: "Shopkeeper, you take a good look first, if you don't want this batch of nine-star iron, don't regret it." ”

"Hey, I really won't accept it!" The old face of the shopkeeper Fang was so angry that his beard trembled, his face was pale, he sneered, pointed to those dimly colored Xingchen Tie and scolded: "Take all this garbage, don't come again in the future, I won't accept it when I come!"

Yin Lan's father was immediately anxious, a piece of three-star quality nine-star iron can be sold for at least three hundred yuan, this batch has a total of sixteen yuan, that is, nearly five thousand yuan of goods, except for this Fang Family Material Pavilion, it is impossible for other shops in Sanshui Town to eat all of them, if he is forever rejected by the Fang Family Material Pavilion, it will be extremely inconvenient for him to sell materials in the future.

At this time, Yin Lan picked up a piece of Xingchen Iron, shook it in front of Shopkeeper Fang, pretended to sigh regretfully, and said, "Since Shopkeeper Fang doesn't want it, then we won't bother." ”

"Wait!"

Suddenly, Shopkeeper Fang suddenly reached out and grabbed Yin Lan's arm, his eyes staring at the Xingchen Iron in Yin Lan's hand.

I saw that on the surface of the star's iron, there were four pale white circular marks.

"Four...... Four stars?!" Shopkeeper Fang's voice trembled a little, and he swallowed a mouthful of spit.

Then the shopkeeper hurriedly lowered his head, quickly pulled up in a pile of dim-colored Xingchen iron, looked through several pieces, and found that the surface of each piece of Xingchen Iron had four pale white circular traces.

This pile of star iron is all four-star!

He has been assigned by his family to work as a shopkeeper in this small town for three years, and the things he usually receives are low-grade materials that have only undergone primary processing and have almost zero technical content, because these things are easy to handle, the cost is very transparent, and there is not much profit at all. For this reason, every time he went back to the family headquarters to report on his work, he felt that his face was dull, and even last year, he was directly scolded by the deputy director of the Chamber of Commerce, who was in a bad mood at the time and drank alcohol, and scolded him with words like "Your performance is a piece of", which made him eager to find a pair of red underwear to put on his head to hide his embarrassment and shame.

Now, he actually saw four-star quality nine-star iron, and there were a lot of them!

Although this can only barely be regarded as something with a certain technical content, compared with the slag materials received before, the profit is several times higher, which simply makes him burst into tears, tears of joy, and tears......

"I want it all!" Shopkeeper Fang wiped the two eye droppings that slipped from the corners of his eyes with the back of his hand, raised his head suddenly, looked at Yin Lan and Yin Zhaoping, and no longer had the slightest anger, but a look of joy on his face, and his tone was crisp and decisive.

......

Out of the Fang Family Material Pavilion, Yin Zhaoping's vicissitudes of life showed an uncontrollable look of excitement, pulled Yin Lan to a corner, carefully observed the surroundings, and then, grabbed Yin Lan's shoulder, and asked excitedly: "Stinky boy, what's going on, how did those nine-star iron become four-star?" It was sold for nearly 60,000 yuan, and the price was more than ten times higher than that of the three-star one. ”

It's no wonder that Yin Zhaoping is so excited, because the profit from a single piece of four-star quality nine-star iron can be worth his income in the past ten days and a half.

Just now, the shopkeeper Fang's attitude towards Yin Zhaoping and Yin Lan was simply turned upside down, and he became amiable, just like the neighbor's kind old man, and he also ordered the guys in the store to set up tea for Yin Zhaoping and Yin Lan.

What's more, the shopkeeper Fang, who had always been stingy, actually purchased all the Nine Star Iron at a price of 3,500 Wen per piece. As for the small matter that the materials were not polished, he didn't care at all, and generously settled a huge sum of 56,000 Wen to Yin Zhaoping!

Before leaving, the old shopkeeper of Fang had a warm smile on his old face, and told Yin Zhaoping that no matter how many four-star quality nine-star iron there were in the future, he would accept it, and in terms of price, he would definitely not let Yin Zhaoping suffer.

Yin Lan heard his father's question and replied confidently: "This still needs to be asked, of course I refined those nine-star iron into four-star!"

"How is it possible!" Yin Zhaoping glared at his son, "Although you have some talent in cultivating spiritual power, you reached the third level of apprenticeship at the age of sixteen, which can be regarded as a genius, but your perception is too weak, and there is no possibility of becoming ......a refiner.

Speaking of this, Yin Zhaoping suddenly stopped his mouth, worried that his son would be hurt by his words.

Because, the problem of too weak perception has been a sore spot for my son in recent years.

If you want to become a refiner, even if you want to become a high-level material worker like Yin Zhaoping, you need to meet two conditions, one is spiritual power, and the other is perception.

Yin Lan is very talented in spiritual power cultivation, he has been cultivating since he was twelve years old, and now it has only been four years, and he has reached the third level of apprenticeship, and it is estimated that in a few years, he will be able to surpass Yin Zhaoping's father, and it is even possible to break through the apprentice level and be promoted to a formal spiritual martial artist in the future.

But perception is innate, related to the divine soul, and unless the life level is leapfrogged, it can only slowly improve with age. Yin Lan's perception is nearly twice as bad as that of ordinary martial artists from a congenital point of view, and he is destined to be unable to take the road of refining, but because he has been exposed to Yin Zhaoping since he was a child, his dream is to become a refiner, so this blow has made Yin Lan depressed for a long time.

But now Yin Lan didn't care about this problem, but smiled, looked confident, and said, "Father, that's all in the past, I have my own chances." If you don't believe me, go back to the forging room and take a look, there is a porcelain bowl in there, which is a nitrate mixture I concocted. It can slightly change the overall texture of most refining materials in a short period of time, and the softening reaction occurs during processing, and it is a cold softening, which largely ensures the integrity of the material elements and will not easily lose the microelements......"

A series of refining terms, coming out of Yin Lan's mouth, seemed to come easily, as smooth as a squirt of urine, and his demeanor was comparable to that of a brick family and a beast.

Yin Zhaoping's eyes widened, his mouth wide open, and he was stunned when he heard it.

Among these refining terms, the one he could understand was the word "softening reaction". As a material worker, when facing some very hard materials, you need to add some elemental powder to the fire, or apply a reactive agent on the surface of the material, heat it at high temperature, and then process it, which is the most basic "softening reaction".

However, what is this "cold softening"?

Yin Lan saw that his father was suppressed by himself, he laughed secretly in his heart, then coughed twice, and said: "Father, you go back and try to put some materials into the nitrate mixture I prepared to soak them, and then process them, you will find that it is several times easier than before." ”

"Well, that's really that good? Then let's go buy some materials and go home right away. ”

"Father, go back first, just tell me what materials you want to buy, I just want to buy some things. The nitrate mixture is at home, don't you want to go back and try it soon?"

Yin Zhaoping thought of the nitrate gangue mixture that Yin Lan said, and his heart was a little itchy, and said: "Stinky boy, I really can't wait to hear you say that the nitrate gangue mixture is so magical." Give you money, buy whatever you want, forget the materials I want, I'll buy it tomorrow. When you get home, tell me what happened to you, is that enough?"

After speaking, he took out a brand-new cyan metal card from his clothes, which was printed with exquisite patterns and patterns, as well as the words "10,000", which was a large currency of Qinglan Country, and the currency was worth 10,000 yuan.

"Enough. Yin Lan took the money, separated from his father, and walked towards another very large shop in the town......

Coming to a "Mohs Chamber of Commerce Branch", Yin Lan paused and looked up at the plaque.

"Mohs. ”

Yin Lan's eyes, at this moment, became slightly cold, and then returned to normal, walked into this shop, spent nearly four thousand yuan, bought some elemental things in a black leather bag, and then came to a remote alley.

The so-called elemental substances are things like cleaners, nitrate and gangue, which can be used to synthesize reactors, elemental powders and other items, most of which are used to assist in refining tools and processing materials, and some can be used separately.

And the things that Yin Lan is about to prepare are items that can be taken out and used separately and are extremely lethal.

"It feels like to use what the Mohs Chamber of Commerce branch sold me to deal with the young master of the Mohs Chamber of Commerce...... Very good. Yin Lan murmured, his eyes bright and deep, like a starry sky.

In the depths of the starry sky, there was a blood-colored cold killing intent.

He began to mix the materials on the ground, and after a quarter of an hour, four black balls were made, the size of walnuts, which looked rough and uneven.

Yin Lan put the four black balls in his jacket pocket, his expression was a little more relaxed, and he said to himself: "Fortunately, this 'Burst Bomb' only needs to know the formula ratio, it is not difficult to manufacture, and there is no requirement for spiritual power level." ”
