Since all the four northfall cities on the Huls Continent have been evacuated, all the grain transported to the north on this continent has only been left as a passage in Fog City. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

As a result, from January 840 in the Faimon calendar, the Misty Town Grain Exchange became busy, and in March, the grain gathered from all directions finally completely crushed the grain exchange, which was still expanding.

The mountains of wheat are waiting to be transported to the Knight Federation through Fog City, but with the throughput capacity of Fog City, it seems impossible to complete this task.

To this end, Mr. Merkel also specially suggested to Downer through the Transphonic Circle that some of the tens of thousands of laborers who were building a reservoir in the southern part of Santan Province could be transferred to Fog City, which has solved this urgent need.

In the eyes of Merkel's aides, with the size of Fog City, even if all 70,000 laborers were crammed in, it would not help. In this regard, Grande, who was transferred from the position of supervisor of Falling Rock City to manage labor on the reservoir construction site, was the one with the most right to speak.

In fact, petty officials like Grande, who were ordered to evacuate from other cities in the north, secretly held the mentality of watching the excitement of this capacity crisis.

In their opinion, Duke Vane's scepter can cover the Thorn Empire and the Silver Bird Federation, which means that he is powerful and can manage things like laborers transporting food, which cannot be solved by power alone.

At this time, a piece of news that was gradually confirmed made them see the arrogance of the young duke - he actually told Merkel that Foggy City did not need to add even one more laborer.

However, in the state of mind where everyone is worried, doubtful, anxious or simply waiting to see the show, the capacity of Fog City has gradually increased since late March, and has reached a jaw-dropping speed since May.

In the end, the mountain of wheat piled up in the Misty Town Grain Exchange was swallowed up by Fog City before the fog period at the end of May.

Only a handful of people in Santan Province knew what was going on, but to all the dwarf craftsmen, dwarven warriors, and engineering students in Fog City, the result had been decided at the beginning of March, and no one had ever worried about it.

It all started with the clockwork battery.

Generally speaking, the beginning of a new technology is the fastest development period, and the clockwork battery is one of them.

For more than two years, under the remote control guidance of Donner, the Far North has been experimenting with various secret metal synthesis ratios, as well as more complex and meticulous heat treatment processes, and the performance of spring steel has been steadily rising.

Two years later, the mainspring batteries used in the first batch of batteries produced at the Wucheng plant were far behind the current material performance, and correspondingly, the three mainspring batteries that were initially shaped were too large and heavy to be out of date.

In February 840, three new mainspring batteries were produced at the Fog City factory to replace the Santan, Pamplo and Oviere mainspring batteries that had been finalized two years earlier. Among them, the Santan 2 is two-thirds lighter than the one-ton Santan 1 two years ago, and the volume has been reduced to a quarter due to the more sophisticated structure and stronger transmission materials.

The energy density of the clockwork battery was greatly improved, and finally the clockwork locomotive drawn by Donner on the drawings had initial use value.

On March 11 of the same year, the first four-wheeled locomotive equipped with a Santan 2 clockwork battery was put into trial operation at the Wucheng Factory.

On this day, all the factories in Fog City were suspended, and nearly 1,000 dwarf craftsmen, dwarven warriors, and students from the College of Engineering crowded into the 37th workshop of Fog City (that is, the 37th Street of Fog City), which had undergone three widenings, and witnessed this carriage full of grain, under the personal operation of Master Venn, drive steadily through the freight passage on the inside of the workshop, and drive into the clockwork elevator in the shaft at the end of the workshop.

From this day on, this simple wind-up locomotive, which is nearly three meters long and about one meter five wide, uses four heavy-duty carriage tires, and has a rated load of 350 kilograms, undertakes all the transportation of goods in the interior of Fog City.

By the end of May, there were already more than 200 such locomotives in the entire Fog City, and they were all being transported round and night except for changing the clockwork next to the hydraulic winding machine in the 36th workshop of the Fog City.

More than 200 dwarf craftsmen had the honor of becoming the world's first locomotive drivers, and because of the time constraints, each of them was certified after only two days of training.

However, the wind-up locomotive only had a top speed of just over 30 kilometers per hour, which was only a little faster than a normal bicycle, and the dwarf craftsmen were good at operating the machine, so there were no accidents that could be called accidents, except for a few scraping incidents that caused a war of words between the drivers or the dwarven stevedores on both sides.

These trucks, which only make mechanical noises when they operate, together with the easy-to-operate, stable and reliable clockwork elevators, have raised the cargo throughput capacity of Fog City to a level never seen in the world.

However, all these changes are only happening inside Fog City for the time being.

In the same year, the first artificial reservoir covering several thousand hectares on the mainland of Hulse was successfully built in the southern part of the province of Santan.

It was also in this year that a privatization reform led by Wesley and implemented by Jimmy began to operate in Maple Leaf County, Santan Province, and more than 100 windmills sprung up in villages large and small in Maple Leaf County.

However, in the entire three northern provinces, no one can realize that a world-changing change is quietly brewing.

Late one night in September of this year, a strange clockwork locomotive slowly drove out of the entrance of Fog City, and under the cover of night, it drove towards the wilderness southwest of Misty Village.

The locomotive's tires were much thicker than those of a horse-drawn carriage, and the axles that connected the four tires were supported by intricate metal links and long springs, and there seemed to be no room for loading cargo except for two people.

That's right, it's not a wagon, it's a clockwork-powered off-road motorcycle designed to load the Magic Ballista.

The special heavy-duty mainspring battery loaded on the car can travel at a speed of nearly 60 kilometers per hour for more than 30 kilometers after a full winding, but if you use an ordinary windmill built in the private sector to wind it, it takes two full days to complete the winding.

Fortunately, this locomotive also integrates a three-level wind system to provide magic power, but considering that the magic crystal is too precious and a non-renewable resource, the magic array power will only be used in an emergency.

Now, the first driver of this crossbow chariot is, of course, Donner himself, and Wesley has the honor of being the first passenger. (To be continued.) )
