With Cao Zongbing's fingers, the spectators turned their eyes to the nearby sea.

The sea near the small island of Macau is now densely packed with ships of all sizes. With the billowing black smoke and blue-black water emitted by a few of these boats, it was probably a feeling of black clouds overpowering the city for the Portuguese at this moment.

These vessels come from a variety of sources. There are white-sailed high-speed patrol boats that are already familiar to the Akito, as well as transport ships with wide bellies, and there are also civilian boats and small boats that come to sell agricultural products spontaneously. Of course, the blue-gold gunboat, which is blocking the port outside Macao and sticking out its dense muzzle, will always be the most beautiful and eye-catching boy.

However, the cannon that Cao Zongbing mentioned is not the above-mentioned ships, nor is it the cannon ship that some people think. The Gainburge's fort was located on the western highlands of the island, and the battleships on the sea east of the island did not have such a long range.

The next moment, the answer appeared.

I saw that on the sea not far away, two transport ships spitting black smoke were struggling to sail in the direction of the pier. The reason for the two ships to falter was a strangely shaped rectangular unpowered barge towed behind them.

The three boats, moving in a "Y" shape, did not take long to reach the vicinity of the pier. After that, the ropes were untied and the two tugboats sailed away. The other tugboat, which followed behind, began to slowly push the barge with its bow against the barge's butt. Half an hour later, after a series of fine-tuning, the barge finally docked with the preset landing point near the pier and began to anchor and position.

As mentioned earlier, for this war, the main purpose of the time-traveler is to show.

The display is not only a sea of artillery fire and troops, but also logistics, transportation, medical and other capabilities that are ahead of the times, but also within the scope of the display.

The so-called insiders look at the doorway, and the laymen look at the excitement. The indigenous elite who come here today are from all walks of life, many of whom may not understand the war, but who are equally shocking in other ways.

In addition, putting aside the indigenous factor, this war is also a self-test for the traverser.

Adhering to the concept brought before the crossing, strategically speaking, the Portuguese in Macau City were not taken seriously by the crossers, but they still attached great importance to tactics: since the crossing, the Portuguese who had been defending Macao and had complete artillery fire were undoubtedly the most "regular" and "modern" enemies encountered by the crossing, and they needed to be taken seriously.

This is a "high-tech war".

Therefore, the military is quite serious. There are two reasons: First, this is the first time that the troops have attacked a regular fortress, and the military wants to use this opportunity to test the troops' ability to attack fortifications and gather experience for the future uprooting of the colonizers' fortresses built around the world.

Secondly, this is a joint operation on land and sea. With logistical superiority on their doorstep, troops can rehearse amphibious landings and transports by the way - there is no better opportunity than this.

So for the sake of this war, the military still did a lot of preliminary work. It is worth mentioning that the bigwigs of the navy and army have united unprecedentedly and have united to win quite a lot of resources from the cabinet, so there is a scene of barges docking today.

Of course, barge docking is only the first step, and there are many follow-up actions to follow.

With the thick anchor chains lowered on all sides, the barges that are firmly docked on the shore serve as temporary docks.

At the same time, some engineers who had been waiting on the shore for a long time also boarded the barge. Dressed in yellow or red vests, some of them went to the engine room of the barge to start the machines, and some wore red engineering helmets made of bamboo, holding small flags and whistles on their chests, ready to direct the next wave of transport ships to dock.

In fact, strictly speaking, barges are not unpowered, but power cannot be used for navigation. The barge, named "Linbao 04", was installed with a set of gas-powered traction devices in advance.

The gas power system has now been played by the Industrial Party. Born in the 19th century, the original gas internal combustion engine, with simple parts and rough workmanship, now in the kiln factory, most of the workpieces can be "self-produced". The limit on the number of such internal combustion engines is only a small number of parts that need to be imported.

Although the thermal efficiency of this early internal combustion engine is less than 10%, and the power is not more than 10KW, it is a well-deserved artifact in the plane of traversing. You must know that in the current Ming Dynasty, there is no supply of liquefied gas or even higher-grade gasoline and diesel, so the gas power system that is "coarse", does not pick ingredients, and can use the ubiquitous vegetation of the 17th century to generate power anytime and anywhere is the most suitable machinery for the current era.

After the engineers entered the ship's engine room, they first filled the gas generator shaped like an iron cylinder with the thermal coal stored in advance, and then ignited it. Soon after, with a faint cloud of black smoke rising, the system was up and running.

After the gas enters the internal combustion engine, it provides power. After that, the internal combustion engine began to do work, and when the power gradually increased, the thick iron wheel on the outside of the internal combustion engine began to rotate slowly.

At the same time, the barge terminal is also officially "picking up passengers": a square-headed, slow-moving transport ship is slowly approaching the port.

Up to now, more than an hour has passed since the guidance of General Cao Cai. However, the spectators on the castle tower were not bored, whether it was the generals who spoke loudly and loudly, or the wealthy merchants who were silently crowded in the corner, they were all fascinated by the operation of the dock close at hand.

Later generations of people are full of cars when they go out, there are cranes to build buildings when they look up, and excavators are demolishing when they look down, so they have long been accustomed to the power of industry.

However, in this era, the indigenous people have not experienced the baptism of industrialization at all, so whenever people see that huge and mysterious power, they are always attracted to it immediately.

Although the natives have heard the legend of the iron tools of the Yizhou organ before, how can the language be as shocking as the scene? So the moment the long barge was lifted to the shore, it attracted the interest of generals, merchants, and the people who were all around at the moment. The natives were all watching excitedly, looking forward to the next move...... The natives are not stupid, the natives know very well that building a dock is only the first step, and there must be a show later.

After the square-headed transport ship docked, the bow and stern were also anchored. When the hull of the ship stabilized, something happened that made the viewer snort: the hull of the tall transport ship suddenly cracked.

Soon it became clear to the people: it turned out to be an outer wall panel slowly opening. If you look closely, this siding is shining with a metallic luster, and it turns out to be a large iron plate! The iron plate is large in size, the size of a carriage. As time went on, through the gaps that grew larger, one could even see sailors slowly turning the winch inside the cabin.

As the winch turned, the iron chains on both sides were slowly lowered, and finally, the iron plate "clanged" and landed at the far end of the barge dock, forming a de facto slope.

Immediately after that, from the engine room of the barge, the engineers pulled out two thick ropes and dragged them all the way to the cabin of the transport ship.

Theoretically, wire ropes are to be used here. However, the tall wire rope cannot be produced by the public at present, so it can only be replaced by oiled ropes.

After the rope was pulled into the cabin, it took a long time for a small green flag to wave at the hatch. With the appearance of the small flag, the power machinery of the barge engine room began to output maximum power, so the rope was pulled and slowly retreated.

The next moment, a thick cannon appeared in plain sight.

In fact, strictly speaking, what appeared at the door of the movable cabin was the butt of the cannon, which was a 24-pounder long-barreled naval heavy gun that emitted a black light.

Heavy artillery was placed on a gun carriage. With the pull of the rope, the cannon slowly slid backwards down the steel plate slope, and then continued to slowly retreat under the gaze of thousands of pairs of eyes, all the way to the other end of the barge, and landed on the shore.

Next, another long rope took over its previous position and continued to hook onto the gun mount, beginning to pull...... During the time when the barge was docking, two sets of mobile traction systems had been moved between the pier and the artillery position.

The so-called mobile traction system, in fact, is no different from the components on a barge, it is still a set of gas-powered units, except that the system on the shore is transported in place by horse-drawn carts and then assembled.

In this way, through the relay traction of three sets of mechanical systems, the 2.8-ton naval heavy gun was able to pass through the floating dock and the temporary hardened dirt road smoothly under the command of the engineers waving small flags and blowing whistles half an hour later, and was pulled to the rear of the preset artillery position.

The last step of the artillery into the position can only rely on manpower. A large number of young soldiers swarmed up, pushing and shoving, and placed the behemoth in a circular artillery position surrounded by sacks.

At the same time, the originally silent indigenous audience, perhaps because they had been holding their breath to watch the play, actually shouted excitedly at the same time at the moment when the artillery was in place. For a while, the shouts of the tide sounded up and down the castle tower and even on the nearby sea, and people were expressing their respect for power.

From the moment the first cannon was successfully in place, several transport ships took turns to "unload". And this unloading lasted a whole day.

By evening, twenty 24-pounder guns and fifteen 18-pounder guns were in place. There are many other small-caliber guns that were transported by land, and they do not need to be counted.

In just one day, the artillery positions preset in advance between the gate and the enemy's batteries were filled with cannons with their heads held high.

This huge metal position, which reflected the black luster at all times, not only frightened the Portuguese on the opposite fort, but also made the Ming natives who saw it show a terrifying expression, even if it was a military general: the Ming people had never seen so much steel gathered together, and the cold, large-scale industrial killing sensation shook the hearts of all witnesses.
