"Even my mother's funeral has people who can only attend it in secret." Lin Xu looked at the icon on the tombstone and laughed at himself, "Now it's just a temporary departure for the people of Valhalla, but even remote forces like the Snow Wolf Tribe have golden treasures, how can there not be a few Golden Sanctuaries in the southwest of Valhalla, which is one level higher than Valhalla." ”

"It's impossible for me to face the Golden Sanctuary outside the Winter Mountains now, without the suppression of the Winter Snow Wolf, it's just looking for death."

"I have to improve my strength as soon as possible, but let me choose the building among them......

Lin Xu looked at the icon on the tombstone. Lin Xu originally chose the three attributes of the Demon King's tombstone for the three lines of special, life, and battle, respectively, and now the viscount-level Demon King's tombstone promotion choice is Lin Xu's sixth architectural choice after the subordinate, knight, knight, knight, lord, and baron level. Since there are now two buildings each in the dark sea and the blood source, and there are only two black steel only, it can be seen that this promotion choice is more focused on the black steel line.

The choice of black steel buildings reached three, while the other Hidden Sea and Blood Source each had one.

From the purpose of these buildings, Lin Xu is more inclined to [Haunted Mine] and [Bloodwing Tower], among which the Bloodwing Tower is a very rare building in the game that can increase the extra talent of the race.

However, compared to the Haunted Mine Station, although the game may have limited uses, and even without this building, there are other ways to build various transportation roads, but in this world the meaning of this building is different.

Lin Xu can only rely on the skills brought by his own crossing to obtain additional golden fingers that will help him develop in this world. And Lin Xu wants to develop more powerful, whether in terms of individuals or forces, he has to rely on the situation of the territory. Unless Lin Xu let his industrial group hold back technology to make railways and trains, Lin Xu has no other normal way to quickly establish a transportation network covering his sphere of influence.

Not to mention magical trains and rails like the Demon King's Tombstone that can carry a bit of ghostly menace and autonomous power. Lin Xu could imagine that if he built such a haunted mining station, he could quickly consume gold coins to build a railway network covering all his territory, so that his power could develop faster.

Not only that, but the industrial group under Lin Xu was also able to absorb more ideas for the industrialization road.

In the past six months, under the guidance of Lin Xu, Lin Xu has already had an industrial R&D team composed of dark blacksmiths. However, at present, in the progress of industrial technology research and development, except for the blast furnace, hoisting machinery and musket technology of steelmaking, the progress of the rest of the specific industrial projects is still too slow.

Lin Xu's dark blacksmith shop has ready-made mechanical lathes and hydraulic presses. And in the history of 10,000 years in this world, there has been a pedal type external force lathe in this part of the lathe, regardless of the technology involved in the magic circle. In contrast to the earth, in Roman times, it began to manufacture its first pedal type external force lathe. The world is not technologically advanced in terms of pure machinery.

But when you include magic technology, it's different. In Hoglald, you can see all kinds of magic crystal lathes and crystal energy presses. It can be said that many aspects of the magic industry are not much more effective than the industrial level of the early 20th century in the previous life, but the popularity is far less widespread than the wave of capitalism in the previous life.

But the magic industry, built on magic crystals, does not have a theoretical system that is really based on fully reproducible experimental verification theorems. If the theoretical system of the magic industry is delved into the details, in many aspects, it will pay attention to the sensing ability of a spellcaster, without exploring what happens when that sensing ability falls to the ground.

It was doomed from those details, the limitations of the magic industry. Without a large number of spellcasters, the magic industry would not have been able to move forward in great strides.

As long as he continues to move forward, even if there is no spell caster in Lin Xu's territory, he can finally develop to the advanced industrial level of his previous life, but the premise is that there must be enough industrial population.

Lin Xu struggled for two days, and he still had to think about it for two days, just to think about which was the greater value of the haunted mine station for the acceleration of his future industrial level development or the improvement of the strength of the Blood Wing Holy Mountain.

In the end, Lin Xu still firmly believed that the haunted iron mine was bigger. In the recent raid on the Snow Wolf Tribe, the flintlock muskets developed in Lin Xu's territory have proved a lot that the path of industrial technology in the previous life is not necessarily weaker than the path of wizards and knights in this world.

From the perspective of the wizard's pursuit of truth, the industrial technology of the previous life was fundamentally based on the fact that scientists continued to explore the nature of the world, and then engineers and skilled workers continued to practice those theories that revealed the essence, to design various industrialized products, and to relate to the organizational model structure of the whole society.

The haunted iron mine can accelerate the path of industrialization in Lin Xu's territory, and from a certain point of view, the future is also a road that can support Lin Xu's forces to study and master the truth, which may not be a kind of implicit attention to Lin Xu's personal strength.

"Choose to upgrade to build [Haunted Mine]."

Lin Xu chose the icon of the haunted mining station on the tombstone of the Demon King. The other four icons then disappeared.

"The Haunted Mine has the following properties."

"[Haunted Minecart] It costs 300 gold to build a haunted minecart. The Haunted Minecart can move on its own on the Haunted Rails, and can be accelerated by adding other power components. Haunted minecarts have some undead defense on haunted rails. ”

"[Haunted Rails] It costs 500 gold to build a kilometer of haunted rails. Haunted Rails have a base value of undead deterrence for nearby field units. ”

Seeing these two attributes, Lin Xu's heart immediately blossomed.

Building a kilometer of railroad tracks only costs 500 gold. Lin Xu was overjoyed when he thought of this. It is important to know that the railroad track consists of two parts, the rail body and the sleeper. In the early days of the train, the material of the sleepers was also made of steel. It can be said that the rail shaft and sleepers of one kilometer of rail need to consume tons of steel.

Steel is still a high-priced creation in this world, and most of the time it is used in weapons and armor. And even if the price of steel falls in the future, according to the standards of the previous life, the price of a kilometer of railroad track is much higher than 500 gold coins.

It can be said that the haunted mine station has this attribute, which may be the same as the skill that Lin Xu traveled over, and was affected by the manifestation of the skill during the crossing, which changed the cost of laying rails in the game that was not strictly calculated by argumentation to this world.

Lin Xu can imagine what it will be like when the railway in his territory is smooth in the future, and the train is running.

……

Back at the Snow Temple, Lin Xu first asked Zola to send someone to accompany Victoria back to the Snow Wolf Tribe, and he returned to the camp of the Snow Temple in Viradusa through the Demon King's tombstone in advance.

Inside the Xuezhen Temple,

Lin Xu immediately summoned all the middle and high-ranking officers in the revolutionary army under his command, including Petrograd Minster and others in the industrial group.

In the past two days, Lin Xu also learned about the mineral reserves of the Winter Mountains through the various materials recorded in the Winter Mountain Range in the Snow Wolf Tribe.

The Winter Mountains are home to four tribes that are not far from the Violet Alliance's level of civilization. In the reserves of various minerals, it is very abundant. It can be said that there is no shortage of minerals that are critical to the future development of Lin Xu.

Iron ore, sulfur ore, saltpeter, soda ash, coal, etc., the main minerals are abundant in the Winter Mountains, and even Petrograd and others under the command of Lin Xu have found chloride deposits in the Winter Mountains. This can be said to be great good news for the industry under Lin Xu.

Previously, Petrograd, with the benefit of Linxu, had completed the initial development of an air separator. With the air separator, the three acids and two alkalis, sulfuric acid, nitric acid, hydrochloric acid, soda ash are already available, as long as the industrial group under the command of Lin Xu can use the air separator and water gas method to prepare hydrogen in the future (these high school physical and chemical textbooks have mentioned the corresponding reaction process), and then produce synthetic ammonia, the industrial group under the command of Lin Xu combined alkali production method, then the three acids and two alkalis are complete, and there will be no obstacles on the basis of the complete entry into the industrial society in the territory of Lin Xu.

"Now we are currently receiving a threat from Mount Valhalla. It may be that within this month, the Southwest Yingling Mountain will use the problem of the territory being polluted by the underworld to completely intervene in the Snow Wolf Territory. Behind those people should be the shadow of the Shadow Brotherhood, and then the gold mines in our Snow Wolf Territory will fall into the hands of those people. Zola and Linster quickly thought that in the previous territorial succession disputes, Link was able to get the support of outsiders because the territory was rich in gold resources, and even contained secret gold resources that played a key role in the preparation of secret gold treasures.

"In that case, then simply, we will build hundreds of Demon King tombstones during this time, and through the Nether Mint, we and tens of thousands of Netherworld laborers will dig out all the gold mines under the territory first. Nether Gold Coins are then crafted, which are then used to convert the main labor force of the Snow Wolf Tribe into Dark Blacksmiths. ”

"In this way, in the future, the people of the Snow Wolf Tribe can become our senior workers, and they can provide a large number of industrial people for the future industrial development of the territory."

"Also, now the Demon King's tombstone in my hand can build haunted railroad tracks, and I can think of building a subway network directly under the Snow Wolf Tribe, connecting everywhere and improving the efficiency of all aspects."
