There is no uniform chronology in Baikalmo, and each country has its own method of chronology.

In the millennium from the founding of the Monto Empire to Dicklai Baikalmo, the four continents known to Baikalmo were still at the end of the slave society, and each country still adopted the royal-aristocratic lord feudal system.

During this millennium, the class gap in Baikalmo's society has widened, and the gap between the rich and the poor has reached a terrible level.

However, the nobles ignored the suffering of the people and continued to live in extreme luxury, and the financial and human needs of the war were still passed on to the common people.

As a result, in that terrible era, less than 1% of the 20 billion people in the entire plane lived a life of drunkenness, about 40% of the population was on the edge of the subsistence line, and about 30% of the population lived in dark and dirty alleys, succumbing to those ghost places where even rats could starve to death.

The other 30% of the people are in the lowest class, which is the "slave" with the least social status in the history of mankind and even the entire dimensional civilization.

In stark contrast to poverty and hunger, the extremely fertile land of Baikalmo. If someone had planned it scientifically, the fertile land of Baikalmo would have grown enough food to feed 50 billion people.

In this era of immensity, extreme backwardness, and rapid progress, as long as there is money, you can buy anything, from the state or the army, down to the body or soul of human beings.

The words morality, fairness, and democracy were just a whitewash in this era, a mask used by royalty and aristocracy to hide the terrible and terrifying true face.

This millennium, the entire history of the Baikalmo plane, is called the "Dark Ages". Fortunately, the darkness is narrated relative to the light, and the darkest hour is also the moment closest to the light.

Not only is Baikalmo's weights and measures chaotic, but this plane is filled with all sorts of unbelievable horrors.

The Baikalmo Ocean does not know why, but only the offshore sea near the coastline is inhabited by life, and if you leave the coastline for more than 500 kilometers, it becomes a dead sea.

1,000 kilometers from the eastern shore of the eastern continent, there is a group of more than 20 islands, which form a pattern of skulls, which the Baicalmo rulers call collectively known as Skull Island.

Skull Island as a whole is 20 kilometers long from east to west and 10 kilometers wide from north to south, covering an area of about 200 square kilometers. These 20 islands have no grass, no birds, no animals or plants, only hard bluestone.

No matter day or night, there will be a sound of crying and crying, sometimes like the wailing of many people, sometimes like the mourning of birds and beasts, which makes people shudder when they hear it, or cry for it. Some people suspect that it was the ghosts of the victims who gathered together to cry to passers-by!

Whenever a ship approaches an island, the ship's navigational instruments will fail, and the whole ship will involuntarily crash into the island and die at the bottom of the sea. The people of Baikalmo are intimidated by the island, and because of its shape that resembles a skull, it is called "Skull Island".

In the middle of these 20 islands, there is a huge floating island, which sinks into the water most of the time without a trace, and every 100 years or so, when the double moon of Baikalmo produces a lunar eclipse and overlaps, it will be high above the water, this large island is 10 kilometers long and 5 kilometers wide, and the volcano on the island is even more than 500 meters.

When the main island is fully raised, a raging fire will ignite between the pores of the rocks on the island, and magma will flow out, adding a terrifying atmosphere to the already terrifying Skull Island.

At this time, in the very center of this large island, there was a huge flickering gate suspended on the volcano, which had been going on for 15 days without closing, and out of it came 10 legendary powerhouses, more than 20,000 high-level warriors.

Another invasion of Baikalmo began, the largest, longest, and most brutal since the founding of the Monto Empire, and perhaps the strongest invasion in the entire history of the plane.

In this 50 square kilometers area, the 5 major forces of the Eastern Continent, 8 legions, and nearly 1.5 million troops are defending here, including 800,000 troops from 4 legions of the Montor Empire, 400,000 troops from 2 legions of the Rock Empire, and 300,000 troops from 2 legions of the Kingdom of Guimera, the Alliance of the Gods, and the Land of Bones.

This is the standard for every resistance to an invasion of the Alternate Plane. In previous wars, such a military configuration was able to steadily suppress the advance of the alien plane invasion troops, and even a few times, under the stimulation of bloody wars, the guard troops actually broke into the flashing gate and moved the battlefield to the different plane. Of course, none of the troops who passed through the Flickering Gate came back alive.

In the face of the invading forces with a small number of heterotopic planes but extremely strong individual combat, the joint guard forces of the Eastern Continent still chose to hold on to the spot as they considered stable.

All the troops continued to stabilize their fortifications, because as long as they held their defensive positions, they could only sit back and wait until the flashing doors were closed and the troops of the Alien Plane had no backup supplies.

But this invasion of the Alien Plane is very different than before! The number of troops invading Baikalmo was not only amazing, but the quality of the troops was raised by several steps, which led to a sharp increase in the combat effectiveness of the invading troops!

Led by the 5 legends who first walked out of the Flashing Gate, the vanguard of 5,000 high-ranking warriors commanded by 1,000 elite warriors captured the position of the Kingdom of Guimera with only one charge.

This can't be blamed on the fact that the army of the Kingdom of Guimera is not capable of fighting, it is really that the first round of charges on the heterotopic plane is too strong! A legion of 150,000 people in the Kingdom of Guimera killed 70,000 and seriously wounded 50,000, and the remaining 30,000 were already frightened birds and completely lost their combat effectiveness.

If it weren't for the timely response of the two divisions of the Third Army of the Carmen family of the Monto Empire, the ring defensive position of the Baikalmo Combined Army would have been pulled out of a big hole.

Once the line of defense is breached by the alien invasion forces, they will take advantage of their small numbers and agility to come behind the Baicalmo coalition forces.

At that time, the combined forces of Baikalmo will completely lose their geographical advantage and will be forced to fight a decisive battle with the invading forces in the open territory, and at that time more than a million defensive troops will be thrown into confusion, and the numerical superiority will of course be lost, and the consequences will be unimaginable.
