Kong Qing thought about it for a while, paused, and then replied, "Can you take a step back and sell me Kong someone a face, so that I can defend you fairly?"

It was the two groups of people who fought without distinguishing between you and me, and after hearing Kong Qing's shout, they all slowly stopped.

"Who are you, give you face, what a big person, believe it or not, Lao Tzu cut you!" A local warrior raised a curved big knife and pointed at Kong Qing.

Kong Qing stretched out two fingers to put the big knife aside, and said with a smile, "Under Kong Qing, he is the boss of Jinming Iron Shop, and he happened to meet you in this matter, in broad daylight, it doesn't look good to fight for no reason."

"Lao Tzu doesn't care about this, anyway, the Li family's source soldiers deceived people first, and today we are going to ask them for an explanation! Lao Tzu still doesn't believe it, there is no heavenly reason and no royal law in this city of all things!"

When Boss Li heard this, he immediately retorted, "Evil words confuse the public! The way of heaven has its own heart, how many years have my Li clan source soldiers been mixed in the City of All Things, everyone knows whether the weapons are good or not."

"Yes, Li's weapons haven't had this problem before."

"I bought a gun last month and it's good so far"

"Li's shop has been flowing down since the ancestors, and it will never fool people anymore, and it is not a roadside stall, this is all repeat customers"

The surrounding crowd was also discussing, but most of them still believed in the Li family's Yuanbing shop, which made the local forces suddenly angry.

"What do you mean is Lao Tzu's nonsense?" asked the local warrior angrily.

At this moment, Kong Qing took a step forward, walked to a blacksmith, looked left and right, and said, "That's it, since everyone thinks that you are fine, and the Qing is self-purifying, it is better to let everyone see your workshop to build the source soldiers today, if there is really no problem, then the Li family can also take advantage of today's fame today."

Hearing Kong Qing's suggestion, the surrounding melon-eating masses all nodded their heads again and again, thinking that Kong Qing's suggestion was good, in fact, everyone also wanted to see the scene of these local forces eating Yan.

But how could the Li clan just casually announce the workshop of their own source soldiers, you must know that there are secrets of the Li family's source soldiers in the workshop, and for a while, Boss Li was in a dilemma, showing everyone that although it can prove the quality of the weapon, if you don't show it to everyone, you will suffer a loss.

Just when Boss Li hesitated, the people of the local forces seemed to grab the handle of the Li family, and sneered loudly, "What's the matter, Boss Li, I don't dare to announce what I have done wrongly, if you have the courage, let everyone see and understand, so as to prove that Lao Tzu is not deliberately looking for trouble."

Hearing the shouts of the local forces, Boss Li was immediately angry, "Okay! My Li clan is not afraid of shadow slanting, but everyone knows that every armory workshop is secret, and my Li clan's technology is thought to be imitated by no one, of course, I am not afraid of imitation by people with intentions, but it is so simple to announce it, how can my Li family have a face?"

"Then what do you want to do with the Li clan!" the local martial artist asked rhetorically.

Boss Li's cold eyes flashed, he raised his sleeve robe and pointed at the local martial artist, and said fiercely, "If this weapon is not the responsibility of our Li clan, I want you to apologize to our Li clan in front of everyone present!"

"Okay! If these weapons have nothing to do with you, we are willing to admit our mistakes!" The local martial artist is also a man, but he must also believe that the Li family's weapons are not good, so he dares to take the bold words, you must know that for men, the face is tighter than anyone else, and if you really want to apologize to the Li family, they will inevitably be gossiped about when they go out in the future.

"Hmph, come with me if you want to see it!" Boss Li waved the sleeves of his robe, turned around and walked in.

The general people also followed up with the local warriors to follow up the Li family's source soldiers.

Walking through the hall and coming to the scorching workshop, the craftsmanship of the Li family Yuanbing was also exposed to everyone's eyes.

"Everyone, please!" Boss Li bowed his hand heavily, and then retreated to the corner of the room.

Kong Qing frowned, and the other Kong Qing didn't pay much attention to it, but there was a lot of gold water on the stove that made Kong Qing feel strange, these gold water was all over the ground, it should not have been cleaned up, but the workshop was damp.

After a pause, Kong Qingcai asked a blacksmith, "I don't know what the golden water on this stove is?"

The blacksmith was asked by Kong Qing, and the blacksmith who didn't know whether to say it for a while looked at Boss Li with inquiring eyes, and Boss Li immediately waved his hand and signaled that the blacksmith could continue.

The blacksmith nodded to Kong Qing and explained, "This is gold washing water, which we use to clean the stove, and it takes two hours to forge a source soldier, because the iron essence will be lost to the stove in the forging, which will affect the hardness of the weapon, so after each forging, we will wash the stove with gold washing water."

Kong Qingxiao thought about it, and a little gold washing water was glued to one finger, but Kong Qing's feeling felt that there was nothing peculiar about this gold washing water, but it was such an ordinary gold washing water, but it could wash the iron essence clean.

Seeing that Kong Qing was at a loss, the blacksmith also knew what Kong Qing was wondering about, and immediately smiled, "Don't underestimate the ordinary gold washing water, not only the stove, but some special metals meet the gold washing water, and the iron essence in it will be actively separated."

"In other words, this gold washing water is used to separate iron essence?" Kong Qing suddenly realized, and now Kong Qing was like a mouthful, and his face was inevitably surprised.

Under the blank gaze of all people, Kong Qing clenched his fists for a week, and said carefully, "Everyone, Kong just remembered that there was something to do at home, so he didn't stay long, and said goodbye."

"Well, how did he go"

"yes, haven't you yet made it clear who is right and who is wrong?"

Walking on the street, Kong Qing's pace was getting faster and faster, and the smile on his face was like getting some amazing treasure, and he couldn't suppress the excitement in his heart at all.

remembered what the old man said to Kong Qing before.

"The biggest difference between the earth and the sea iron is that the earth iron itself contains iron essence, and the synthetic black iron is nothing more than adding iron essence to the sea iron, so that the proportion of iron essence contained in the sea iron is the same, to achieve a balance, if you want to increase the hardness of the synthetic iron, there are only two ways, one is to reduce the iron essence in the ground iron, and the other is to increase the sea iron!

"In this way, the earth black iron is equivalent to the carrier of the source soldier, and the hardness and source power are all replaced by the sea black iron!"

This is also a problem that the source soldiers have not solved for many years, because it takes countless years for the formation of the earth black iron to form, and it is this year after year, day after day, that makes it difficult for the iron essence in the earth dark iron to be decomposed.

Now the idea in Kong Qing's mind is basically formed, put the earth black iron in the gold washing water and soak it, didn't the iron essence run out obediently.

With ideas and money, Kong Qing naturally wants to do a big job.

When he returned to the Jinming Iron Shop, he saw the sound of striking iron coming from the Jinming Iron Shop, a thriving scene, and it also gave Kong Qing the determination to study Xuantie well.

"Liu Lao, Liu Lao"

Hearing Kong Qing's call, the old man hurriedly put down the work in his hand, picked up a stack of papers at the counter, walked up to Kong Qing and handed it to Kong Qing, and said with a smile, "Haha, where did you run away with the shopkeeper, this is the bill for this period of time, you take a look"

Kong Qing waved his hand, sat directly on the chair, took a sip of hot tea, and was just about to speak, but looked at the tea in surprise, "Hmm, where did this tea come from, Liu Lao, you bought it?"

Hearing this, the old man shook his head and said with a smile, "This is sent by a girl, saying that it has a wonderful use for nourishing the mind and settling down, I am thinking of making you a cup and letting you taste it."

"Girl, what girl ......" Kong Qing shook his head, it was Kong Qing, who was in a hurry to study Xuantie, and he didn't think much about it, after putting down the teacup, he looked at the old man with a smile, "Old Liu, what do you guess I found today?"

"Look at what you kid is laughing at, say it," the old man scolded with a smile.

Kong Qing turned his head and called to a guy, "Master Wei, you go outside and buy some gold washing water, buy more"

Master Wei wiped his hands and said in a daze, "Boss Kong, what do you want to do with gold washing water, it seems that you don't need these to create synthetic dark iron."

"It's okay, you go buy it first, buy more" Kong Qing waved his hand, and Master Wei could only go out once.

"I said what the hell are you kid doing, why are you drumming and washing gold water, isn't this idle panic" The old man really couldn't think of Kong Qing's mysterious mystery when he came back after going out for most of the day.

And Kong Qing didn't have to explain, but leisurely tasted the fragrant and charming fresh tea.

After a while, Master Wei bought the gold washing water, and under the puzzled eyes of the blacksmith, Kong Qingyou found a large iron basin, and after filling it with gold washing water, Kong Qing put a piece of dark iron into it.

The old man looked at Kong Qing's set of movements, and said very incomprehensibly, "What are you drumming up, the gold washing water is used for gold panning, you put a piece of dark iron ......"

Kong Qing smiled lightly, patted the old man on the shoulder, and then went out for a walk, calculated the time, and after an hour, Kong Qing slipped back to the shop.

Kong Qing had just walked to the door when he saw the blacksmith and the old man squatting on the ground gathered together, and on the ground was the dark iron that had been soaked in gold-washed water for a whole hour.

"How is it, has there been any change?" Kong Qing laughed and walked in from outside the door.

Hearing Kong Qing's voice, the blacksmith and the old man hurriedly stood up, "How can you kid do this, this ...... This gold washing water, the iron essence of this dark iron has been separated."

Kong Qing walked in front of everyone, glanced at the basin, and sure enough, just as Kong Qing thought, the silver and silver of the earth black iron were washed and blistered, and there was a thin layer of bright sand floating on the water, and this layer of bright sand was also iron essence!

Kong Qing took out the earth black iron in the basin, revealing a long-lost smile, "Liu Lao, didn't you say it before, the way to increase the hardness of synthetic dark iron is to reduce the amount of iron in the ground black iron, now I will separate the iron essence in the ground black iron cleanly, if you use this piece of ground black iron and sea dark iron to create a piece of synthetic dark iron now, you say that the hardness is ......."

"Yes!" the old man nodded solemnly.

The other blacksmiths looked at Kong Qing with slightly dull eyes as if they had discovered a new continent, "Boss Kong, this is to make history......

Without any waiting, he bought a lot of gold washing water, soaked all the dark iron of several squares, and at night, pieces of brand-new synthetic dark iron were sent out of the stove by the blacksmith door.

Looking at the new synthetic dark iron on the table, the joy on Kong Qing's face was so brilliant.

The old man walked up to Kong Qing's side, "Let's ...... Got rich......"
