As the busy time passed, the temperature gradually dropped in late autumn, and this winter, Gu Yi had too many things to deal with before he could start his development plan at the beginning of spring.

But the [Bluestone Mine] that he took over from Gao Jie was simply an empty shell, there was nothing, everything needed him to build from scratch, and for a while, Gu Yi was so busy that he couldn't even take care of the matter of practicing the [Jade Camp], and threw it to his subordinates to be responsible.

Thinking that they have experienced their own period of hell training, they will definitely be better than the blue, and they will do a very good job!

In fact, a few months later, when Gu Yi remembered to conduct a review, he found that they had indeed done a very good job, and even had the initiative to invent more torture methods, and to train those warlords and subordinates in a fastidious manner......

In order to meet the coming winter, Gu Yi first needed to complete the work, that is, to build the planned Limin Village, but the wood was enough, but the processing methods of the Limin almost collapsed.

In order to get a plank, craftsmen often use axes to split a whole log little by little into a thick block that meets the requirements, and then use a planer to plank it little by little, how much wood does this have to waste?

Gu Yi checked the tools used by the craftsmen and found that the shape of the carpenter's tools was similar to that of the carpenters in his impression, but it was more primitive, and the most important saw was there, but the saw blade was thick and short, the tooth pitch was large, and the material was still iron, this thing was not so much a saw, but a wolf tooth sword with teeth!

This thing is used to saw a log with a small diameter, or a small piece of wood, but it can't handle large timber at all, no wonder the craftsmen would rather use an axe to slowly chop and chisel than use the hard guy, who is caught in the log after two pulls and can't pull it out, and it is not hard enough to use that one.

After inquiry, I learned that there are high-grade saws, but the kind of long saws made of [fine iron] are mostly owned by [craftsmen], and they are extremely rare [famous weapons], and ordinary craftsmen can't touch them at all.

According to Gu Yi's guess, this [fine iron] long saw is nothing more than made of iron with good hardness and toughness, and it may not even be considered steel, but it can be regarded as a treasure?

Gu Yi racked his brains for a while and found that if he wanted to make a qualified saw blade, he had to study crucible steelmaking first, and to make crucible steel, he had to make crucible steelmaking first!

Gu Yi scratched his head frantically, is this about to start climbing the technology tree?

As a last resort, Gu Yi had no choice but to roll up his sleeves and began to study how to copy out the various technical materials recorded in the "Goldfinger Usage Guide".

Fortunately, it is not difficult to make crucibles by soil method, and the clay, graphite, porcelain clay, quartz and other things that make crucibles can be found on the bluestone mountains.

Poor Gu Yi, a guy who didn't pass the handicraft class when he was in school, suddenly wants to be an "inventor", it's too difficult for him, even if there is a detailed manufacturing method in the "Goldfinger Usage Guide", but when he looked at this thing, he just had a fun mentality, how could he write down all the huge content, even if Gu Yi studied it for a while, it can only be said that he has an impression.

After many failures, Gu Yi couldn't help but sigh when he looked at an extremely ugly deformed crucible, this wants to be a great inventor... No, it should be that it is not easy to be a "big copycat"!

Ugly is a little ugly, but it can barely be used, Gu Yi couldn't wait to let people get iron materials and start local steelmaking, and after a lot of twists and turns, he finally used the "frying steel method" to make a pot in a daze, even Gu Yi himself didn't know that Lu Dao should be regarded as that kind of steel molten steel.

Among the craftsmen, there are a group of blacksmiths drawn from the [Iron Battalion] such as [Hammersmith], [Little Hammersmith], [Force Craftsman], [Anvil Maker], etc., who were originally pounding and tossing to make crucibles and frying steel, and no one has yet figured out what he is doing.

But when the molten steel was cooled and formed, it was sent to the Qianshan [Craftsman Battalion] station, a master craftsman picked up a piece of steel ingot and knocked it a few times, and his face suddenly changed greatly, this thing turned out to be very similar to the legendary [Xuantie]!

At present, the Great Wilderness is still using the "block refining method" of charcoal ironmaking, that is, the iron (pig iron) sent from the mine is repeatedly forged after being burned red and softened to become iron that can be used to make weapons, which is the so-called [mortal iron] (wrought iron), so a large number of [force craftsmen] and [anvil makers] are needed in the [iron camp] to carry out this boring manual labor.

And [Fan Iron] is refined by the secret method of [Craftsman], and ten [Fan Iron] are refined into one [Refined Iron], and [Famous Weapon] can be made that is hard to find.

But [fine iron] is not the best quality of iron, the so-called [dark iron], is the heavenly stars fell into the world, extremely rare, with [fine iron] to make [famous] level weapons, only need to invest a few [dark iron], you can get [treasure] level Xuan soldiers, this kind of heaven and earth treasure accidentally descended, can cause all sides to rush madly, the city does not change!

Although the quality of this crucible steel refined by Gu Yi is not as good as that of [high-grade dark iron], it is not far from the quality of [low-grade dark iron], and it is definitely far better than the [fine iron] grade of [famous weapon], the most important thing is that this thing can be artificially refined, without waiting for the stars to fall from the sky!

The so-called [famous weapon] and [treasure weapon], there is no concept of so-called "immortal" in the Great Wilderness World, and the corresponding is the "celestial man" equivalent to "immortal", so there is no such thing as "immortal weapon", taking the meaning of "heaven and earth sage, Xuanhuang Lingbao".

In the Great Wilderness belief culture, "heaven and earth" is the largest, followed by "gods and man", and the "man" here refers not to mortals, but to "heaven and man", referring to the first generation of "ancient ancestors" born with heaven and earth when chaos first opened, also known as "spirit man", which is in line with the saying of "heaven, earth, and man".

And "Xuan, God also." Spirit, holy also. Therefore, "Xuanling" also has the meaning of "gods", so that the order is: "Heaven and Earth Xuanhuang" is [product], and "Sage Lingbao" is [order].

The heavenly and earthly treasures in the great wilderness are divided into: heavenly products [holy rank], earth products [virtuous rank], Xuan products [spiritual level], and yellow products [treasure level], which are "four products and sixteen orders".

The items that mortals can make cannot be listed in the "Four Grades and Sixteen Orders", and those things that are beyond the ordinary quality and lower than the quality of the Heavenly Treasures are roughly classified as: Mortal products [famous vessels] are listed below the "Four Grades and Sixteen Orders".

Therefore, Gu Yi is in a daze, as if he has tossed out another incredible thing!

Gu Yi used graphite, quartz and other materials to burn the crucible, many people in Limin Village have seen it with their own eyes, and it didn't attract much attention originally.

And when [Xuantie] came out of the oven, Gu Yi was talking about using black gold gall (graphite) and chalcedony jade (quartz), which are materials that only practitioners can use, and the behavior of mining black stone (charcoal) to produce "fire in stone" to forge the "Ding furnace" was naturally associated with strange places.

The rumor that "the battalion commander (Zuo Ling) is good at cultivating the arts, is the reincarnation of a celestial man, and is good at refining Xuantie Star Gold!" The rumor that Gu Yi did not know was secretly spread by the craftsmen, and quickly fell into the ears of some "people with a heart", such as Ziyu, and then quickly passed the secret to Nanwan Hao Shang Zhenning, confirming some "speculations".

In order to climb the science and technology tree, Gu Yi finally got out of the steel, and the master craftsman who was busy making saw blades would know about these secretly spread rumors, but he felt that the subordinates who were usually just respectful to him suddenly worshipped.

When they walked there, there were people staring at them intently, and there were even people who were far away, "Let's go!" and bowed to the ground, and before they could walk over and teach him to perform a "military salute", they got up and turned around and ran away as if they had seen a ghost.

Sometimes the action is slow, and he is caught in time to run, no matter what he says, people have a reverent expression, "mmmm" listen to his lesson, never return the mouth, there is a lot of spit on his face, like a spring breeze, Gu Yi is confused and not depressed.

After a long time, Gu Yi could only mumble a few words: "I don't want to have the idea of a personality cult!" Let them go, after all, it's quite cool to be worshipped.

With steel, Gu Yi summoned several masters of the [Iron Battalion] to study how to make saw blades, but those masters were so solemn that they almost burned incense and bathed before they started to do it, and they were so serious about what they explained made Gu Yi a little embarrassed.

Gu Yi himself also knew that this kind of thing made by the local method of steelmaking must not meet the requirements of high-speed steel for saw blades in his memory, but the craft of steelmaking belongs to technical work, and a lot of experiments are needed to master it thoroughly.

This [frying steel method] is particular about the technique of stirring, or the amount and timing of sprinkling iron powder, but the pot he made, in order to skim off the residue, a pot of iron is wasted about half, too wasteful, not to mention, the steel ingots produced are estimated to be low-carbon steel at most.

The most important thing is that he did not add tungsten, molybdenum, chromium, vanadium, cobalt and other alloying elements when refining, and the material was not up to standard at all.
