Everything must be done according to one's ability, and once you go too far beyond your own strength, it is simply self-defeating. Just like Qin Shi Huang repairing the Great Wall and Emperor Yang of Sui repairing the Grand Canal, the value and vision of future generations are all feats that will benefit the future.

But on a single dynasty and an emperor, this is simply the behavior of a tyrant, and the profligacy of the people's power eventually leads to the unstable foundation of the country and the hidden danger of destruction.

As a time-traveler, it is very important to use history as a mirror. If you want to break through the mountains and rocks, in the absence of modern machinery, you need at least explosives. Otherwise, relying on manpower or the principle of thermal expansion and cold contraction to break the rocks, this 50-kilometer mountain road will not be thought about for a year and a half.

Gunpowder has been brought from the Cyris Empire in the East, but it has not been popularized. Duke had also seen gunpowder from the Dwarven Musketeers, and it was a very primitive black powder, which was quite backward in terms of power and combustion efficiency.

Of course, no matter how backward it is, it is used for quarrying or blasting many times faster than manpower efficiency. However, the problem now is that the dwarves do not have much black powder in stock, and it is no problem to use it as a musket to propel it, but if you want to use it to build roads, the power of black powder must be calculated in at least tons.

If you want to produce gunpowder quickly, you still need to solve many problems and raw material problems, and then build roads after producing gunpowder, it is estimated that the daylily is cold.

The idea of rebuilding a fast mountain path is not very realistic for the current Storm Castle. Then Duke can only consider the second method, which is to use the existing roads and horse-drawn carriages to speed up transportation as much as possible.

As for how to speed up transportation, Duke actually has a set of plans in mind, that is, to get on and off the carriages of this era, so that they can run faster and carry more load!

In this era, the carriage on the continent of Europa has surpassed the entire feudal society of China. The reason is very simple, that is, because of the appearance of the four-wheel steering system, without this system, then the carriage is almost stuck on two wheels, once on the four wheels, there will be a situation where the rear wheels cannot turn according to the front wheels. Just as the American civilization never invented the wheel, the Chinese civilization, a branch of the science and technology tree, has never been lit.

This is not to say that there were no four-wheeled carriages in ancient China, but that almost all four-wheeled carriages in ancient China were forced to turn. There is nothing wrong with a light load or a wide road, but once the load is twisted, it will cause serious damage to the axle mechanism, and all the load capacity is greatly limited.

However, it is not the steering system that Duke wants to modify, because even if future generations of cars continue to use this set, there is nothing to modify. There are only two things Duke wants to make, suspension and ball bearings!

The spring suspension system, which required good metallurgical support, did not appear until the late Middle Ages, and the ball bearing was not invented until the eighteenth century.

The carriage of Fort Storm climbed over the Saint-Michel Mountains, and due to the bumpy roads and the lack of shock absorption, in order to prevent damage to the axle and the overall structure of the body, it could only carry two or three hundred kilograms, which was a bit small for a four-wheeled carriage. You must know that the heavy carriages of the Napoleonic era had a load capacity of 1.5 tons, a gap of more than five times!

Therefore, the suspension suspension system is imminent, but Duke did not choose spring suspension, but chose to use the simpler leaf spring suspension, that is, the combination of steel bars to form an elastic beam, which is also a common solution in modern trucks. The shock absorption effect of this scheme is certainly not the best, but the advantage is that the structure is simple, the cost is low, and the maintenance is a matter of changing the steel plate, which is very suitable for the current situation of Storm Fort.

If spring bending is still a bit difficult for Stormcastle's current technology, then making a long spring steel bar is no longer difficult for Stormcastle's smelting technology. As for the ball bearing, if you want to grind out steel balls before you change it, even if you can succeed, you can imagine how slow the labor efficiency is, and it is estimated that it can't keep up with the speed of damage to the carriage bearing.

But with a hydro grinder, all this is possible. As long as the rough embryo steel balls are mixed together, oil, coarse abrasives, etc., the coarse grinding can be completed. Then wash and replace with fine abrasives for fine grinding, and finally manual polishing.

Although this is certainly not much slower than the industrial production of later generations, it is at least countless times faster than manual labor, and it should not be a big problem to deal with the wear and tear of horse-drawn carriages. Once the ball bearing is successfully applied, the damage rate and maintenance difficulty of the carriage in Storm Castle will be reduced exponentially, which will be an epoch-making technology for the carriage, and it will almost reach the level of modern carriage.

Duke told Galileo what he thought and what he had planned, but unlike the excitement he had imagined, Galileo was completely stunned by a dream. Because these plans have exceeded Galileo's current thinking span, they are completely fantastical ideas for him.

But after Galileo was stunned for more than ten minutes, he finally slowly figured out the revolutionary technology of the Duke plan, which if applied to the carriage, whether it is speed or load capacity, it will be multiplied. It can be said that even if the road is not built, Storm Castle will be able to bypass Alpine City and become self-sufficient!

"My lord, what you said is so amazing that I can't do it alone. I think that in order to really apply it to the carriage, it needs to go to the hydraulic factory and gather the joint efforts of carpenters, dwarven blacksmiths, etc. ”

Hearing Galileo's words, Duke nodded, although these seemed to him to be just two simple little things, and almost everyone in later generations knew about them. However, if you want to make it out in this era, it needs the cooperation of all kinds of talents, and it is impossible to fully understand it by relying on a scientific pioneer Galileo.

Thinking of this, Duke couldn't help but sigh, it seems that it is not possible for him to be lazy and be a shopkeeper, once there are too many things beyond the era, only by himself can he understand his intentions.

The modification of the carriage is a top priority for Stormcastle at the moment, as Alpine City could cut off trade routes at any time. So Duke led Galileo to the hydraulic factory on the spot, gathered Copperbeard and Bruno, and began to renovate the carriage.
