At dawn, as soon as the sky dawned, Alcatraz was already bustling with people.

Compared with when Tang Jie left, this place has changed.

Tang Jie invested all the funds in the construction of the fortress on Alcatraz Island regardless of the cost, and the abundant funds and a large number of slaves made this sea fortress change every day, and the construction speed of the fortress was jaw-dropping.

In particular, the role played by the two dwarven craftsmen was not to be underestimated, although they devoted almost all their minds to the research and construction of submarines, but in their spare time, through the inspiration of Tang Jie, they invented a few tools that brought earth-shaking changes to Alcatraz Island.

The first thing that appeared was the tie-rod piston machine, which had a thick iron handle at one end, and shaking the iron handle could produce a strong force through the air pressure of the air, so as to drive the mechanism at the other end, and this mechanism was a large lifting machine formed by combining gears one after another.

When the fortress of Alcatraz Island was built to a certain extent, it was necessary to build a slope and high platform, and in order to transport the stone weighing several tons or even a dozen tons, the slaves and sailors on the island adopted the most primitive method: put a round roll of wood under the stone, and then push the stone forward by a crowbar, and continue to stuff the log rolled out of the back in front of the stone, and so on.

This method is labor-intensive, slow, and unsafe, as a stone rolled down last time, killing not only two Dadas, but also a large piece of wood.

But with the birth of the dwarven craftsman's invented rod piston machine, this problem was solved, and the slaves only needed to shake a huge iron stake at one end of the rocker to transport dozens of tons of stone to a high platform of more than ten meters or even tens of meters.

The power of the machine is extremely powerful, these dark-skinned, muscular Dadas carry huge stones, under the command of Bill and others, slowly put the stones into a lifting platform, and then the lifting platform makes a sound of Krakala, slowly rises to the heights, and then the slaves on the high places unload the stones.

This invention immediately gave the two dwarves a very warm welcome and reverence on Alcatraz Island, and they greatly freed up the labor of these sturdy black slaves, allowing more people to devote themselves to the construction of the fortress, rather than the endless labor and time in the process of transporting stones.

Soon, though, these two guys, who seem to be arguing forever and not doing their jobs, invented another guy that stunned everyone.

Steam engine!

In Tang Jie's previous life, human civilization has a history of more than 4,000 years in the process of up and down 5,000 years, which is at an extremely low and slow forward speed, and the most important symbol that distinguishes the human process from the Middle Ages to modern times is the invention of the steam engine, and the process of human civilization has entered a new era with the invention of this instrument.

Whether it is a power plant, a machine processing plant, or a car, a ship, an airplane, or a computer, the source of the construction of these things is related to the steam engine, so to speak, without the steam engine, there would be no modern civilization.

And Tang Jie, using the greatest advantage he crossed over, brought this almost bug-like machine to this magical world, as if he had inadvertently sprinkled a little spark on a grassland, will this grassland eventually be able to ignite the prairie with a spark, or will it use its profundity to drown this spark in it?

Tang Jie, who was far away in Garcia, didn't know, and neither did the dwarf who invented the steam engine, let alone the others on Alcatraz.

All they know is that this guy only needs to constantly burn the steam pot with fire, and then transport the huge pressure generated by the water vapor to the piston machine through the square steel pipe, and then drive the machinery through the force generated by the piston to produce powerful and incomparable mechanical energy!

Now the slaves didn't even need to push the heavy irons of the piston machine, they just had to throw the coal from the ship into the boiler and burn it.

It's also a shame that these two dwarves are apprentices of the two master craftsmen, Shoshennik and Saiya, otherwise the steel sealing technology alone would be enough to give people a headache.

As for how they could make such a sealed machine out of these incredibly hard steels, the rest of Alcatraz couldn't figure it out, but given that the dwarves, a race of skilled builders, could build battle robots as tall as castles, they didn't think it was unusual for these two quarrelsome guys to build such a machine.

It's just that this kind of combat machine is operated by the power of magic, which is extremely expensive, and they are cheap and can be operated and built by anyone!

With such machinery, Alcatraz Fortress was built more than ten times faster, and the first thing to be completed was the square front city of the fortress.

This is a front-line wall on the beach on the west side of Alcatraz, it is the first defense system of the entire outer line of the fortress, the thickness of the wall reaches an astonishing one and a half meters, the walkway of the city platform is wide enough to run horses, and the height of the wall is a full fifteen meters, parallel to the cliffs on both sides.

The vast majority of ordinary castles were built by human and simple mechanical forces, so they could not use thicker stone to build intricate forts, but this is no longer the case on Alcatraz.

After a heated argument between the two dwarven craftsmen, the inside of the thick frontier wall was built by Alcatraz's strong laborers using the power of machinery to build four floors, each of which was built with a row of gun mounts and dug out dense cannon holes, and as soon as a battle was fought, the wall immediately turned into a terrifying fortress full of cannons from top to bottom, not just the cannons at the head of the city, as is the case with normal fortresses.

The outer wall of the fort, which was to be completed, sealed off almost all of the western beach, and at each corner of the fort wall was a tall circular watchtower equipped with a giant cannon to guard against each other.

The beach on the west side of Alcatraz Island had been completely abandoned at this time, and a huge wall had been erected out of thin air in the place where the fierce beach battle had taken place in the past, and although the soil under the wall was still a little blood-soaked black and red, there was no trace of that fierce battle elsewhere.

In its place, there is a fortified fortress that makes you gasp at the sight of it!

The women of some of the Dada tribes, as well as other remote tribes of the southern continent, climbed along the unremoved wooden platforms of the sea, and applied a kind of paint mixed with cow dung and wood pulp and mud to the city walls, and when this paint dried, it became hard and slippery, not only to strengthen the fortress's resistance to artillery fire, but also to prevent people from climbing up the edge of the fortress's stones.

Above the city wall, some slave craftsmen bought by Tang Jie are building semicircular forts, arrow stacks and lookouts on the city wall, these people are busy on the gray and white city wall, looking like a group of industrious and hard-working ants working hard to build their nests from a distance.

As the construction of the outer city gradually came to an end, the construction of the inner city also began.

Hawke, a skilled builder, built the fortress into a strong-guarded square fortress at his behest, while Barnes, a skilled builder, set out to build the inner city into a terrifying killing machine.

The distance between the inner city and the outer city was actually only from the beach to the entrance of the cave where the Black Dragon King of Alcatraz Island was, because the huge creature of the Black Dragon King was stranded on the beach, and no one could move it, so the construction of the inner city could not be carried out for a while, which made Barnes so angry that he pulled his beard.

However, for Nia, the number one person in charge of Alcatraz Island at the moment, the construction of the inner city is not the most critical, the most critical is the purchase and installation of cannons.

Although the cannons brought by Darius were all good breech-loading guns, she knew that the royal fleet of the Pound Empire was generally loaded with large-caliber howitzer guns, which not only had a long range, but also had fierce firepower, and the rate of fire was nearly twice as fast as that of breech-loading guns.

Nia felt that if she wanted to install it, she had to install the best, and it would be good to have a batch of breech guns on top of the fortress, but if the range was not as far as the other side, and the opponents lined up on the sea and bombarded themselves with cannons in turn, and they could only be beaten, then this fortress would not have the slightest point in construction.

Therefore, the fortress cannon must be the best and strongest, otherwise it is better not to install it!

But this kind of large-caliber grenade cannon is strictly forbidden by the empire to be bought and sold by the people, they are strictly controlled in the hands of the empire, and no one else can touch it at all, where can I get this kind of cannon myself?

Nia was secretly worried in her heart, but what made her anxious and unable to sleep was another thing.

Tang Jie's whereabouts.

Since Tang Jie was attacked and fell into the sea with the enemy, he was like a stone in the sea, and there was no more news, at first Nia went crazy and led the pirates around Alcatraz Island to frantically search for Tang Jie's whereabouts.

But the pirates drove the ships and searched around Alcatraz Island round and round, and as the days passed, their hearts sank little by little, until the voices of doubt finally began to appear: "Accept your fate!
