These craftsmen who have also encountered the bottleneck of the realm, although they are not like the old dwarf, who have lived in seclusion for decades in order to break through the realm, but they are also struggling to find a way to break through through various methods and means.

Now that you suddenly hear that someone has found a way to break through the realm, how can you let them not fall into a state of madness?

The vast majority of these famous craftsmen and skilled craftsmen are people who have already established a sect and established a college and have a career background, so naturally they can't take refuge like a lonely person like Forging Yekui, who has enough food and the whole family is not hungry.

Then, the easiest solution is to send the disciples and grandchildren under their name to the Qingshi Mountain, in order to join the Tiangongmen, learn the skills of the secret classics, and then bring the skills back to their original sect.

Even these artisan clans can't resist the temptation, not to mention those ordinary craftsmen, when the masters urgently pass the news back to the sect and gather their disciples to come to "study", it is not surprising that the news will be leaked out, which naturally caused an uproar among the great wilderness craftsmen, and suddenly caused a wave of "immigration tide" of the craftsmen

A large number of craftsmen, like flies that smell blood, flocks from all over the Great Wilderness, have already added a large number of people to Bluestone City out of thin air in a short period of time, and I heard that this is only a relatively short distance, and it is estimated that it will take half a year to arrive on the road

Gu Yi knew very well that if these famous craftsmen and skilled craftsmen did not have some "bait", I am afraid that there would not be too many people who could stay after the most decoy, so before sending people to take them to "visit and study", he deliberately strengthened the defense and confidentiality work of various construction sites, factories and mines.

As for some core processes and important production workshops, they are strictly guarded in accordance with the standards of military bases, and outsiders are strictly forbidden to approach, which allows them to only see what they can't eat, and take a symbolic tour of the periphery.

And he himself is avoiding the other party to live or die and not meet, really can't hide with busy affairs, recently has no time to hold a lecture on "Heavenly Creations", occasionally mentioning a few sentences is also vague, throwing out a "fake big empty" technical theory, hooked these craftsmen masters salivate, but can only scratch their ears and cheeks to understand the principle, first whetted the other party's appetite before talking.

As for those of the lower-grade craftsmen, Gu Yi handed over all the brains to the forging and smelting kui, and those who were willing to sign the "deed of sale" of the "Confidentiality Agreement for Techniques" were assigned to the major workshops according to their respective strengths, and directly invested in the construction site.

Professional is professional, with the help of this group of craftsmen who are also at the lowest level, after they quickly became familiar with and mastered the "high-precision" tools provided by Tiangongmen, the construction speed is almost increased by geometric numbers, and the entire Ishihara construction site presents an extremely vigorous development atmosphere.

As the cold winter gradually passes, the bluestone city is gradually completed, and all that remains is to wait for the climate to be warmer and drier.

For example, with lime, gypsum, porcelain clay, indigo, white zhang (chalk), ochre and other materials, mixed with a kind of perennial thick vines called wood gum and hemp vine, the juice squeezed out of the boil, similar to paint, the exterior and interior walls of the building are painted, one for beauty, the other is for waterproofing

It is said that when he paints wood, he often uses this kind of gum gum and rattan juice, mixed with tung oil and rosin to make wood paint, and the lacquered wood is not only smooth and oily and durable, but also insect and moth-proof, and the smell is fragrant.

This kind of extremely similar to architectural paints, aroused Gu Yi's curiosity, lime, gypsum, porcelain clay, is nothing more than to fill the cement wall bubbles to make it smooth, and the role of indigo, white Zhang, ochre, is to change the color of the paint, so that it presents different colors such as cyan, blue, white and red, it is not surprising.

What really made Gu Yi curious was this substance that acts as a "film-forming binder", and when he looked for it in person, he couldn't help but be stunned, because this thing was extremely similar to rubber, but it was not collected from rubber trees.

I asked the master of the Seven Workers, and I learned that this kind of perennial wooden vine called 丨 wood gum hemp vine 丨 grows all over the mountain, and the growth rate is fast, if ordinary hunters and woodcutters want to go up the mountain to hunt and cut wood, it is difficult to move an inch without cleaning them up.

The most hateful thing is that the hemp vine containing this gelatinous juice will have a pungent smell and dark smoke when burned, and it is not even worth burning as firewood.

Moreover, once the milky white juice of this kind of hemp vine gets on the skin and clothes, it is not only difficult to clean it off, but the skin will itch and fester, so even hunters and woodcutters are reluctant to go to the mountains covered with this kind of hemp vine.

However, although the very sticky juice squeezed out of this kind of hemp vine is regarded as poison by the people of the Great Wilderness, it can prevent insects when used on wood, so it is used by craftsmen as lacquer and adhesive glue.

Gu Yi listened to it called a sweat, although the varieties are different, but this Nima is rubber, okay?

Paint the exterior walls of buildings with rubber as paint?

extravagant

It's a fucking luxury

If it weren't for the fact that tung oil and rosin were far more difficult to obtain than this kind of "hemp rattan gum", Gu Yi estimated that the master of Qigong would be able to paint the building as wood

The appearance of hemp rattan gum gave Gu Yi an unexpected surprise, because with the appearance of this material instead of rubber, he could push the technology tree to a higher level and create items such as tires and seals.

Some of the problems that had bothered him, such as the sealing problem of the steam engine boiler, were also solved with the advent of rubber

It's just that for the use of this new material, I'm afraid it will take a period of time to test it before it can be put into use, and Gu Yi has no energy to make any inventions for the time being, because with the passing of winter, a lot of things are waiting for him to deal with.

For example, after a busy winter, Binning has achieved remarkable results, not only for the empty horse road construction agency investment company" to pull a large number of customers, the first batch of orders for the horse road of Qingshan Mansion, nine cities and eighty-one forts, but also in accordance with Gu Yi's requirements, in Zhucheng and Zhubao, get the land of the Trap Empty Furniture City and the Trap Food City.

In addition, with the efforts of Zhenning, a large amount of grain and various materials and raw materials have also been transported by water for a whole winter, continuously filling a large number of giant warehouses built near the sand wharf, and constantly transporting them to the bluestone city and Qingwa city through the Sha Wai Ma Road.

And the population requested by Gu Yi, Zhen Ning even collected all the subordinate camps and subordinate columns of Qingshan Mansion, and scavenged craftsmen from all walks of life as much as possible, but it was really not enough to make up 20 million, so it was replaced by Qingzhuang Limin.

After one winter, the population of Bluestone City has been pushed to nearly 5 million, and it is expected to complete the migration of the remaining 15 million people by the end of the year.

丨Qingshi City丨 entered the stage of completion and drying, but Gu Yi did not let the people stop, due to the tenfold surge in population, he directly let 丨Qingwa City丨, 丨Shachang City丨 start construction at the same time, put in saturated labor, and build at the fastest speed.

At the same time, the city walls of the three cities were also started at the same time, as long as the Qingwa City was expanded nearly 100 times in one winter, and various building materials supplied by various factories and mines, Gu Yi even wanted to enclose the three cities with a Great Wall-style wall of more than 50 kilometers

After seeing the miracle of Bluestone City rising from the ground in a winter, Zhen Ning, Ziyu and others have begun to get used to Gu Yi's crazy behavior, and his plans can never keep up with the changes brought about by his "construction rhapsoia".

After a winter, not only did he have an additional Battlefield City and three city walls, but if it weren't for the production speed of building materials, he really couldn't keep up with the consumption rate, so he didn't plan to build a Salt Brine City.

Fortunately, the horse road order brought back by Zhenning required a large amount of cement, which slightly suppressed Gu Yi's "construction mania" and began to free up the share of materials to lay the horse road on a large scale.

The only thing that made Zhen Ning very depressed was that Gu Yi, who had collected a large number of people in a short period of time, was resolutely unwilling to allocate manpower to the work of laying the horse road, but only sent a horse road construction engineering team as a guide.

丨Bluestone City丨 is only responsible for the supply of building materials, and all the manpower for the construction of horse roads is responsible for Shicheng and Rongbao, which are connected by various horse roads, and the labor under his name is all invested by him in the crazy construction of his territory.

In addition, the master craftsmen who were dried by Gu Yi for a winter finally settled down when spring came, except for some famous craftsmen who were attached to the names of the princes and heroes, and they really couldn't help themselves, two-thirds of the other famous craftsmen and skilled craftsmen who had autonomy chose to stay.

They even made the decision to sign Gu Yi's technical confidentiality agreement, which is equivalent to a "deed of sale", to join the Tiangongmen as an "external technician", and began to move the sect under their name to Bluestone City.

It's no wonder that their willpower is not firm, but in this winter, they who stayed in Bluestone City in the name of "research and study", whether it is their senses or their hearts, have been greatly impacted and shocked by all kinds of novelties in this city of miracles that have risen from the ground.
