Lu Huang looked at Tang Zheng without answering.

But Tang Zheng didn't need an answer - of course it's now, it can only be now!

His heart suddenly became tight.

You know, this is a casting master like Lu Huang who has a hands-on teaching opportunity on the spot. If you tell me, I'm afraid even casting lecturers from top academies in major families will be snatched away!

Tang Zheng immediately did not feel pretentious and put away the casual smile on his face: "Please give me some advice."

Lu Huang nodded with a smile and continued to say one by one...

"You should also understand the method of stone pressing, which is a process of removing mineral impurities, separating effective raw materials, and then purifying them."

"The entire process of purging is divided into four steps: inspection, grinding, purification, and purifying!"

"The inspection is a process of using astral force to sense the type and internal structure of the ore, and think clearly which part of the ore you want to extract in the end."

"Milling is rough processing, removing the parts with the most impurities on the outside of the ore, leaving only the parts where the essence needs to be extracted."

"Purification is a finishing process, further removing all the useless impurities in the minerals, leaving only the essence."

"The purity is the last step, separate the mineral essence and transform it into the material you need in the end."

"Among these four points, the first step of checking and selection is very important. It determines your ultimate goal and detailed method. Many people ignore this point and believe that only the last three steps have higher requirements for skills. It is more worthy of attention. In fact, it is not... Of course, checking and selection is a step that requires accumulating experience and cannot be achieved overnight."

"Now, watch me demonstrate the whole process of suppression for you."

Lu Huang briefly explained the process of pressing stones to Tang Zheng, and casually took a piece of gravel the size of a palm on the ground.

"Start the selection first. I use star power to constantly visit the inside of this stone, feel its density, structure and resonance characteristics for star power..." Lu Huang said, and used star power to extend it to the ordinary stones in his hand.

I saw the star power slowly sinking into the stone, and a very faint star power line gradually lit up on the stone, like the capillaries of the human body. It is small and complicated, and I walk on the entire surface of the stone.

The interiors of the raw materials are uneven, and even Lu Huang extends the star power into the raw materials, he is very careful...

"Taiyin is friendly, amorphous porous structure, with a lot of impurities, and high fire resistance... I want to suppress the Taiyin Yuan iron in this stone." After Lu Huang used star power to check the stone, he came to the conclusion of suppression.

Then, he closed his fists!

I saw the stone being pinched in his hand. His five fingers turned gently, and debris fell from the stone.

Soon, the stone was a big circle smaller.

The original irregular shape also turned into a smooth and small goose-shaped goose!

"The process of grinding is very important. The three-word key is fast, accurate, and ruthless. The movements should be fast, and the miscellaneous removal should be accurate. The polishing should be ruthless. After Lu Huang demonstrated the grinding, he explained the key key points to Tang Zheng.

"Then... it is purification. Purification must be pure and good, and it must be condensed without dispersing." Then, Lu Huang's star power continued to extend out, and the star power veins once again lit up on the pebbles.

However, this time the light is much brighter than before, and the veins are thicker and denser, and has evolved from capillaries to the aorta.

The star power slowly flowed on the stone, and the pebbles seemed to have expanded entirely...

Lu Huang opened his mouth and blew it gently, and a burst of stone powder smoke floated out of his hand, leaving only the veins that were still shining with the glimmer of star power.

Lu Huang's fingers moved slightly, and the veins slowly merged, and the astral power slowly subsided.

Then, a small piece of silver-black metallic gloss was left in his hand.

"The last step is to suppress the simplicity. Under high pressure, good materials will be formed!" Then, the star power surged out from Lu Huang's hand, gradually completely wrapped the entire stone that was only a small piece.

The star power that wrapped the stone became more and more dazzling, as if it was about to completely crush the small piece into its palm.

In the end, Lu Huang removed Xingli.

The only one left in his hand star was an iron grain that was the size of a rice grain, shining with a sharp cold light!

"Taiyin Yuan Iron has been completed." Lu Huang glanced at Tang Zheng and continued: "This place is worthy of being the main star pole. Most of the surrounding stone ores have been contaminated by star force for many years, and their properties have mutated. Even the stones that could only purify ordinary cold iron on one side can completely crush the Taiyin Yuan Iron. This small piece can be worth half a purple gold Tongbao."

"..." Tang Zheng looked at the small iron particles in Lu Huang's hand, and he was slightly jealous.

Such a small piece of Taiyin Yuan iron can be worth half a purple gold Tongbao, it is really "turning stones into gold"!

If I practiced the "stone suppression method", I would have to make money every day and make money...

"Damn, why did you think about making money again? Shopping your hands and buying things!" Tang Zheng said despised himself.

"Okay, you can try it yourself." Lu Huang signaled that Tang Zheng could start trying.

Tang Zheng took the stone in his hand and passed Master Lu Huang's explanation and demonstration silently in his heart.

He took a light breath and tried to extend Xingli along his fingers into the ordinary stone.

When I watched Master Lu Huang's demonstration, it was extremely relaxed, but when I tried it myself, Tang Zhengcai realized that even if it was just a step of checking, it would be extremely difficult.

This ordinary stone has no resonance at all!

As soon as Tang Zheng's star power extended to the surface of the stone, it immediately received great resistance and was difficult to enter.

"No wonder it is said that nodding is harder than climbing to the sky." Tang Zheng was blocked by his first attempt, but he just laughed at himself without any discouragement.

He recalled the process of the star power flow when Master Lu Huang used star power to check and selected it. He felt a move in his heart and no longer used brute force to force the star power to extend it, but turned the star power into a trickle.

"Water has no normal shape, and turns the star power into flowing water. Try slowly and soak slowly..." Tang Zheng changed the way the star power extends and finally achieved good results.

Although, compared with the speed of Master Lu Huang's selection, it is not the same as that. However, compared with before, great progress has been made.

Slowly, under the influence of Tang Zheng's patient star power, his star power gradually penetrated into the stone.

"It's still affinity with Taiyin, well, it seems to be crystalline structure, not metal..." As the star force enters, it senses the route and speed of the star force flow. The structure and impurity distribution inside the stone gradually form a prototype in Tang Zheng's mind.

Finally, as demonstrated by Master Lu Huang, a small star power vein also lit up on the surface of the stone in Tang Zheng's hand, flashing with a faint star power light.

"Hu..." Tang Zheng's forehead was covered with fine sweat beads, but he didn't care about wiping it. He was already thinking about the next step of grinding the ore.

...

According to Master Lu Huang's demonstration, the two steps of grinding and purification, relying on Tang Zheng's powerful star power control did not cause much obstacles to him.

The only problem is that Tang Zheng is now like a layman who peels fruits for the first time. He is still very unskilled in his movements.

Therefore, during the grinding and purification process, many of the originally useful minerals were also abandoned.

Seeing that there was only the essence stone as big as a fingernail in his hand, Tang Zheng smiled. He began the last step, and the most difficult step - scrutiny.

In Tang Zheng's understanding, it is to use star power to create a high-pressure environment, change the internal structure of the material, and ultimately change the properties of the material.

"Tsk, this is the process of turning carbon into diamonds!" Tang Zheng recalled the key points of the sacredness and couldn't help but complain.

Like Lu Huang, a large amount of star power surged out, completely wrapping the essence of the stone in the palm of his palm.

Tang Zheng used the star power and kept shrinking the star power in his palm...

Shrink, shrink, shrink again!

Tang Zheng gritted his teeth and focused all his attention on the little bigger fingernail in his palm.

The beads of sweat as big as beans were all flowing down their faces.

However, he obviously felt that the pressure was not enough, so he could turn the essence of the stone in his palm into a high-quality crystal material with a tighter structure and a more neat arrangement.

pity……

Tang Zheng even used all the strength to feed himself, but he still couldn't finish it.

"Strength is a flaw!" Tang Zheng once again felt that the quality and total amount of star power were not enough, and even casting was greatly affected.

what to do?

Give up and get a stone that is easier to crush?

Tang Zheng was a little confused...

Giving up halfway is definitely not Tang Zheng's style. He gritted his teeth and suddenly had an inspiration in his head.

"The magnitude of pressure is related to the area of ​​force and the pressure itself. When the pressure is constant, the smaller the area of ​​force, the more significant the pressure effect..." This introductory physics knowledge flashed through Tang Zheng's mind.

Tang Zheng decisively condensed the star power, gathering it like a needle, and pressed towards the essence of the stone in his hand from all sides at the same time.

It works indeed!

Feeling that the original stone essence was finally crushed a little, Tang Zheng felt relieved, and then patiently compressed the volume of the stone essence little by little. He could clearly feel that the properties and texture of the stone essence were changing accordingly.

"Ha, it's done!" I don't know how long it took, Tang Zheng's heart moved and put away the star power. A small transparent crystal lies in Tang Zheng's palm, shining.

"Perfect cutting, eight hearts and eight arrows, flawless under the mirror..." Tang Zheng looked at the crystals that were as thin as sand in his hand and said intoxicated.

Holding the sand-like crystal in his hand, Tang Zheng handed it to Lu Huang: "I will start dealing with the Fu Bi Broken Chen Stone now?"

"..." Lu Huang glanced at the crystal in his hand, then looked at Tang Zheng, "I barely understood the basic practices of suppressing the cun..."

"Uh?" Tang Zheng was stunned. He thought he was a genius and could learn it once. Unexpectedly, before he could be proud, he was poured down by a scoop of cold water - he could only be considered "barely known" after a long time.

"Well, you have taken the first step to suppress the law, which is very good." Lu Huang threw a few more broken stones over, "Your foundation is very good, let's continue practicing!"
