Seven hours after the landing, Zhao Xuanwei turned on the projector in the temporary military base, and on the projection screen was a sand table map of the entire Qianao Island.

Zhao Xuanxuan, on the other hand, pointed his finger on the east coast of the map and zoomed in on a beach area, and a square on the map appeared on the projector after zooming in.

It was a platform, hundreds of meters long, that appeared out of nowhere on the beach. Then it extends to the sea to the depths of the water, which is obviously a pier.

The platform is overgrown with various shells. The scout shoveled down with a shovel and could see that the platform was cement. It is a human structure, and to be precise, a remnant of a sea man.

After the Age of Godfall, terrestrial humans and ocean-dwelling humans were separated. When communication between the two races is lost (the transportation facilities of ships and planes are interrupted), the two human races are separated.

From today's point of view, the human technological society of the ocean in the Age of Godfall fell more completely, because the ocean lost its convenient transportation, and the reconstruction of civilization was far more difficult than that of the land. Sixteen hundred years ago, when the steamships of the Oka people had just expanded into the Southern Ocean, they saw that the sea people were still using ceramic (enamel) swords and fuel spears.

However, in the early days of the Divine Fall, the sea humans still achieved the same achievement as the land humans - that is, to wipe out other marine intelligent species on the ocean.

The core reason is that the agrarian economy fights the nomadic economy, that is, the advanced fight the backward.

This is because farming is able to form population clusters around stable production areas. And in the population concentration there is enough to form a rich handicraft. After the Age of the Godsfall, the sea humans were able to make wooden sailing ships in large quantities and were able to fire high-temperature ceramic arrowheads in large quantities. Metal weapons capable of smelting enamel and rust resistance. It can burn a boatload of quicklime and throw it into the sea to form a dead zone.

Nomadism, on the other hand, could not gather together steadily, and since the interpersonal society could not provide a stable place to live, it could not produce craftsmen who were thoroughly engaged in handicrafts.

Those ancient sea tribes had much stronger magical talent than sea humans at that time, but their culture was nomadic and lived in schools of fish. After the fall of civilization, they lived according to their own culture.

At that time, marine humans lived stably in the shallow waters of the continental shelf and cultivated seaweed.

Cultural habits determine the social economy, and the social economy determines the fate of the race.

More than 20,000 years ago, the ancestors of the sea human beings were able to pull out hundreds of times sailing ships and transport hundreds of tons of lime at every turn. When the material is finished, it is crushed.

As a result, in the endless hatred of those native races, the 'remnants of humanity' dragged away the original diversity of marine intelligent life.

Back to the topic, sea humans are a farming people, and the crops they farm are seaweed.

And these seaweeds are naturally to be treated. Drying in the sun is a long-term storage method for marine humans. In the east of Qianao Island, it is precisely an excellent shallow sea planting area.

At present, the platform on Zhao Xuanyu's projection cloth is located due east of a large natural shallow sea area, which is a natural agricultural reclamation area for sea people.

Fifteen hundred years ago, the entire Qianao Island was the territory of the Hanhai tribe of sea people, who harvested kelp and would find stones on the shore to dry it, and then transport it to the freshwater pools of the southern hinterland islands, where they were hydrolyzed by microorganisms to produce starch.

In the industrial age, the boulders used by the sea to dry kelp were turned into concrete platforms. At present, the cement platform that Zhao Xuanyu is looking at is a relic of two hundred years ago, and it has been cleaned twice in the last ten years.

The reason why the sea humans completely abandoned this place two hundred years ago was because the sea surface temperature in this area became unstable, and red tides appeared in a large area of the shallow sea of the eastern continent.

The powerful sea human forces temporarily retreated southward, while the land humans of the eastern continent took advantage of the situation to seize Qianao Island. But in the last two decades, a series of facilities that appear to be sea humans in the northern seas have been built. Make the hydrology here controllable. began to dispatch forces to recapture Qianao Island.

It's getting dark.

Su Ying returned to his station. The fortifications in the garrison were completed, and barbed wire was put up at several intersections. The surrounding jungle has been set up with remote-controlled mines. Military dogs were even pulled out of their cages, fed with stimulants, and dragged out for vigil.

After Zhao Xuanwei saw that Su Ying was safe, he sent Su Ying back to the warship in the port, and he gathered the captains on the land military base to make arrangements for the island map.

Zhao Xuanxuan: "The sea humans are now active on several large islands in the southwest, and their invasion force is about 500 to 2,000 people. They'll be there this week. I can tell you that the new magical lineage of the Sea Humans is very different from ours. Technology is also the same as us. ”

Zhao Xuanyu turned on the development technique, and a three-meter-diameter, six-legged, turtle-shaped mechanical body appeared on the visualization technique. The Mechanical Turtle of Imaging is divided into seven, and on the seven optical models, the Mechanical Turtle can be modified with different modules.

Some turtles have mechanical batteries on their backs, some have mortars on their backs, and some have rocket launchers welded on their backs.

Zhao Xuanwei: "Biological organisms have been eliminated on the mainland. But on the ocean, the sea humans still keep it. In every conflict, this metal monster is the leading force. The heavy firepower of its loading was terrifying.

Therefore, everyone should avoid the edge, and when the enemy tries to land, timely arrange anti-heavy armored mines to obstruct them. ”

Manifestation then switches to another unit, which is an infantry unit, but wrapped in iron. When equipped, the weight is more than three hundred kilograms. More like power armor in the interstellar age. During combat, these armored infantry will cover the landing of the turtle-shaped mech.

Zhao Xuanwei: "The development route of marine human power suits is different from ours, and the core of their territory is a large shallow sea continental shelf, so the development is amphibious, that is, switching to a swimming form underwater. ”

The mecha in the image enters the water and transforms into a form with multiple blades agitated, and its specific swimming posture resembles that of the leafy pods, the Cambrian overlord of the Odd Shrimp (now extinct).

Zhao Xuanyu: "So on land, their walking state is very bloated, but their armored areas are very thick. "—The primary indicator of all mechanical armor of terrestrial humans is speed.

Zhao Xuanwei marked the defensive armor modules on this bloated mecha in red on the imaging technique, focusing on the weak points of the joints and armor gaps on the mecha.

The tech tree of the Sea Humans is completely different from that of the Land Humans

First of all, their internal combustion engine technology tree, the internal combustion power is not as good as that of landed humans. Because the terrestrial environment depends on speed, in the marine environment, seawater provides hiding, and of course, seawater resistance also hinders the development of high speed and high power.

The amphibious mecha of the sea humans is simply not light. Moreover, the machinery and equipment that have to be soaked in water for a long time have buoyancy support in action. Excessive size does not affect mobility. Just as animals tend to grow larger in seawater. The mechs of the sea humans have also increased in weight over the past few hundred years.

Now, when the sea humans have more than 20 tons of mechas, they directly come to the shore and raise a 20-millimeter caliber chain cannon and shoot at the shore. The propeller then stirs the waves and retreats into the sea. Leaving only traces on the beach and sea waves, this operation is like a crocodile predator, which makes the land humans who have not had time to mobilize heavy firepower very confused.

Moreover, although the sea humans did not take the internal combustion engine technology, they did take the power technology. In particular, the technology of aluminum sheet using seawater electrolyte discharge is widely used on the mecha of marine humans, and their mecha has not eliminated biodynamics, but the operating system is extremely electronic.

The career system of the sea humans is also completely different from the three high-level career systems of the land humans, the Great Wall, the general, and the authority. There are only two career series, and these two series do not say that there is a distinction between lower, middle, and upper, but are distributed according to the level from one to nine.

The topic is back to the present.

In the camp tent, in order to deal with the sea humans, which is completely different from the land humans, Zhao Xuanwei attaches great importance to tactics.

In terms of equipment system, all of them are equipped with combat uniforms, although three-quarters of them are only carbon fiber power exoskeletons, which are lower in price than combat uniforms and inferior in agility.

But the ability to carry a long march with a load is higher, and it can carry a weight of fifty kilograms, and conduct combat operations in rugged areas like an ordinary person.

In this combat distribution, Zhao Xuanxuan placed the team wearing agile combat uniforms at the front of the theater of operations, and the soldiers with weight-bearing exoskeletons in the later positions.

Front-line infantry collects forward information.

Negative reorganization can carry long-range individual rockets to provide precise support on the battlefield.

Of course, all personnel have the same electronic communication equipment for individual soldiers.

Under Guangling's strong suggestion, Zhao Xuanwei did not engage in equipment differences in this regard, and everyone's battlefield communications could be transmitted to the command headquarters through high-altitude relay airships.

The situation on the entire island unfolds like a game map at High Command.

And Zhao Xuanwei can conduct a deep battlefield perspective on any area at any time - send Su Ying to the combat area, and the transparency of the battlefield will be doubled.

Zhao Xuanwei, who has been exposed to military books since he was a child, carefully practiced what he learned when he was young. They are mobilizing their bulldozers and digging trenches and building defensive walls in some key areas.

When Zhao Xuanwei was busy, Su Ying (Guangling) didn't have any speech, this coastal operation, Su Ying didn't understand.

On a warship.

Su Ying looked up at the starry sky in the sky, and said silently: "Sea Human, an unknown area. In the previous life, danger has always been neglected, and when I find it, I can only choose to end. So now, well, where the hell is it? ”

The opponent mentioned by the Reincarnation Light Group this time, Su Ying has never forgotten, this opponent, Su Ying is not sure where it is, so he has to take a look at every place.

In the sky, the bright planet slowly walked through a distance.
