There are all kinds of earth fire caves here, from the primary to the highest, and there are everything.

Moreover, the earth fire here is extremely stable and always maintains a specific flatness and temperature.

Of course, it is very simple to increase the temperature or lower it.

These modern thermostats set up around the ground fire can help you solve this problem successfully.

With this weapon refining valley, Lin Ze did not lack knowledge on weapon refining, so soon, Lin Ze began his first weapon refining.

It is difficult to refine weapons, which is something that all warriors know very well, and this is also the reason. Is there not many refiners in the mainland of China? Every refiner has a high status?

Even if the weapon refiner is very low, only at the fourth or fifth level of the acquired world, many times, innate warriors will give him face.

But for others' extremely difficult refining weapons, it is really easy for Lin Ze to refine them now.

Because Lin Ze has induction, especially in the plane seed world, where Lin Ze's induction does not require mental power. It is like a talented ability, Lin Ze can be fully open.

The most important thing in refining weapons is to master the heat, the frequency and material changes when refining weapons. These are all hidden under Lin Ze's induction.

Therefore, for Lin Ze, it is as simple as one plus one equals two for refining weapons that is difficult for others.

Just like calculating a math problem of twenty by twenty digits, it takes a long time for ordinary people to calculate it, and the accuracy rate cannot be guaranteed. However, if you have a computer, it will take a few letters to enter, and it can ensure 100% correctness.

Lin Ze is now equivalent to a person with a computer, while others are like those who do not have a computer and need to draft.

There is no comparison between the two at all!

I don’t know how long it took, but the sound of the iron suddenly disappeared. Lin Ze directly sent the sword embryo in his hand into the ice water on one side.

"Chi..." A somewhat harsh sound suddenly sounded, and then a rich white smoke was seen floating up from the ice water.

This white smoke was very big, even covering Lin Ze.

"Ha ha……"

When the smoke dissipated, Lin Ze raised the sword embryo in his hand and looked at it carefully in front of the sunshine above his head. Soon, his face was filled with a satisfied smile, and there was also a laugh in his mouth.

"Very good, this time I finally shot a suitable good sword, hahaha..." Lin Ze kept smiling inside his mouth, and he was very satisfied with the sword in his hand.

Lin Ze has been refining swords for three days. Although Lin Ze has magical sensibility to help, refining weapons is not that simple, not to mention that Lin Ze was the basis for refining weapons before.

Not to mention anything else, it took Lin Ze two days just to make a fuss on the frequency of ironwork.

Lin Ze's sensitivity can help him understand when to put the hammer, but the strength of his hands is still not well controlled. It was not until two days after contacting each other that Lin Ze will be able to ensure the output of the strength of his hands. Now, Lin Ze's refining can really start.

However, even though Lin Ze mastered the strength output later, his next weapon refining was also full of failures.

Lin Ze had mastered the power of the lower hammer, but he had not mastered the landing point of the lower hammer, so in the next day and a half, Lin Ze directly refined fifty sword embryos of his subordinates. Every time the sword embryo was broken, it was because the lower hammer point was not well mastered.

Fortunately, Lin Ze has the induction, so after this day and a half of practice, Lin Ze has now mastered the hammer point.

Look, this new sword embryo was refined successfully.

Looking at the sword he had refined after working hard, Lin Ze's mouth was filled with joy.

However, soon, Lin Ze slowly restrained the smile on his face. He stroked the sword body and muttered to himself: "I have only refined a sword embryo now, and there is nothing to make a fuss about."

Lin Ze slowed down for a moment and quickly continued to say to himself: "The most important thing is to engrave the sword embryo. Only by completing this step can the sword on this side be truly refined successfully."

"Fortunately, I have the induction, so this is the easiest thing for me to engrave the array pattern that is most difficult for other weapon refiners."

Thinking of this, Lin Ze smiled at the corner of his mouth.

Why are there so few weapon refiners?

The reason is that it is difficult to engrave array patterns on the refined tool embryo.

The weapon refiners here do not have modern magnifying glasses or microscopes, and they do not have Lin Ze's induction. Therefore, they engraved array patterns on the embryo, which really relies on their own eyes and their hands that have experienced tens of thousands of times, or even hundreds of thousands of times, to test continuously.

The hardships in this are something that ordinary people can persist in.

Just like the micro-carvings in history, before the appearance of magnifying glasses, there were extremely few micro-carving masters, and the price of each micro-carving was extremely expensive, because there were very few micro-carving masters at that time, and it could even be said that there were only a few micro-carving masters in those days.

With the help of magnifying glasses in modern times, there have been more micro-carving masters, and the price of micro-carving has dropped rapidly.

Lin Ze is now like a person with a modern magnifying glass in his hand. The difficulty of engraving the array pattern is countless times smaller than that of ordinary weapon refiners.

In addition to the feeling and control of frequency that Lin Ze refined when he used to refine the sword embryo, the difficulty of engraving array patterns on the sword embryo is no longer there.

But to say that, this is the first time Lin Ze has engraved array patterns on the refining weapon, so Lin Ze still took out 200% of his attention to doing this.

Lin Ze first took a deep breath, and then took a short needle made of amethyst from the side that had been prepared long ago.

Amethyst is a type of Yuan stone. It not only contains sufficient spiritual energy, but is also extremely hard, and is also the best conductivity of true energy. Therefore, amethyst is the best spiritual material for engraving array patterns.

Picking up the amethyst needle, all the true qi in Lin Ze's body began to flow slowly, and then a trace of true qi was poured into the short needle smoothly and orderly. Soon, half an inch of light flashed on the tip of the needle.

The light on the tip of the needle was unstable and an unparalleled mysterious light burst out.

However, this was the first time Lin Ze engraved the array pattern, so he was very careful. When manipulating the true qi, he did not input a large amount of true qi at once, but a very small input.

Therefore, the bright light on the tip of the needle is constantly sucking, but the light is not big, just like the glimmer of light released by a small candle at night, swaying with the wind, as if it will be extinguished at any time.

Lin Ze ignored the bright light changes on the needle tip. He was concentrating on all his energy at this time and constantly strengthening the impression of the array pattern in his mind so that the subsequent array pattern engraving could be smoother.

At this time, in Lin Ze's eyes, this small light was already his entire world.

"Let's start!" Lin Ze said to himself calmly.

With a "furo!", Lin Ze gently raised his right hand, and then the light between his fingers fell on the long sword he had refined before.

Lin Ze's movement was very light, and there was no sound in the middle.

The surroundings suddenly became very quiet, but in Lin Ze's heart, he could clearly sense the slight changes and sounds caused by the friction between the light and the sword body.

This change is not big, and it will not even affect the quality of the sword body. If you simply observe with the naked eye, it will be difficult to detect these mutations in the sword body.

This is also the reason why there are so few weapon refiners. It is really difficult to engrave array patterns.

If you want to discover the above changes, you can only use modern equipment, Lin Ze's induction, or experience accumulated through tens of thousands of exercises.

The traveler had seen a video about the manufacturing of high-speed rail tracks. When the rails of high-speed rail are closed in pairs, the error needs to be ensured to be extremely small, as small as half the size of hair.

Such errors are not only troublesome and cost a lot of time, but also cannot guarantee 100% error-free.

So this is how the final problem was solved?

It's very simple, it depends on the difference in contact between two rails by the human fingers.

To do this, you need to touch countless times to feel the error between the two.

Only after tens of thousands of times or even hundreds of thousands can the accuracy of the error be ensured.

The same is true for alchemists. Only after countless experiments can they master the engraving pattern and eventually become a weapon refiner.

However, it is too difficult to do this. Many people give up because they can't stand such hardships in the middle.

If it were Lin Ze, if he had no inductive help, he would not have become a weapon refiner.

It’s not that Lin Ze did not persist that way, but that Lin Ze did not have the time to be a weapon refiner.

He still has countless refugees to settle. Cities such as Huangsha Town, Heisha City, and Jifeng City are waiting for him to develop. These things will occupy Lin Ze's seventh floor. The rest of him will have to accompany Ping'er and others around him, and practice, so he has no time to be a weapon refiner.
