After Luo Ji's convoy entered the Western Territory, Gao Su had already prepared a special transport train for them and was waiting there.

I heard from General Rodlin that this train was originally used by them to transport Titan soldiers.

Giant soldiers with a level of 100 meters can be transported, so transporting the horned earth dragon Cook and the black armored rhinoceros will naturally not be a problem.

Now that the war situation in the north is tense, Luo Ji doesn't have time to go to the capital to eat and drink. After getting on the train, he goes straight to the battlefield.

Theoretically speaking, if the enemy breaks through the border and moves in, it will pose a great threat to the defenders.

But on the other hand, the benefits are not without them.

The most direct benefit is that the defensive support distance is shortened.

Originally they might need to support to the border, but now, after the defense line retreats, they only need to support to the second line of defense. The entire support route has been shortened by at least one third.

The sun is scorching hot. Although the season has just entered summer, the temperature has already begun to rise. In the blink of an eye, it has already reached over 30 degrees. Looking at the situation, in the next half month, I am afraid it will rise all the way to 30 degrees Celsius.

The temperature may be thirty-five degrees, or even close to forty degrees.

The coordinates of the Gaosu Empire are located in a tropical area. The winter is not too cold, and the summer is even worse.

This is definitely bad news for the northern garrison.

For some special reasons, Rose Barca's invasion army will pose a greater threat in summer than in other seasons!

At this moment, on the battlefield outside the second line of defense in the north, the enemy's army surged in like a tide.

At first glance, those densely packed and countless ugly creatures are obviously not human beings.

Judging from their body shape, they should be about the same size as goblins. They are covered in gray-black or brown-grey hair. They have a pair of oval-shaped ears on their heads. Their eyes are filled with violent blood. Their noses and mouths are very long. At the same time,

Two sharp buck teeth can also be clearly seen.

The limbs that are slightly too long look uncoordinated against the body shape. At the same time, they are extremely thin and can even be said to be skinny, but they have sharp claws, which makes people clearly aware of this.

biological threats.

That appearance is obviously not in line with the aesthetics of most humans, and can even be said to be very ugly and disgusting.

And the true face of this ugly creature is the Rat Man!

The rat people are a branch of the orc civilization, and they are also a very special branch of the orc civilization.

Their nature is extremely surly and cruel. This character makes it basically impossible for them to coexist with other species, and the "other species" here also include other orcs.

Now that we have talked about it here, we have to talk about the two development models of orc civilization.

From a literary point of view, it can be described as a hundred flowers blooming type and a single flower type.

These two types are actually easy to understand. Just by looking at the names, you can tell that they are almost inseparable.

The let-a-hundred-flowers-blooming type is an orc civilization that annexes all races of orcs in the process of development and develops towards the goal of a hundred races.

The advantage of this development method is that it is comprehensive. Basically, you can find all types of orcs with various abilities. In the future, you can deal with various enemies and even target them! Once developed, they will definitely be very powerful.

of.

But on the contrary, the shortcomings are also very obvious.

Developing together costs a lot of points, making it very difficult to upgrade and unlock items. This is just one of the shortcomings.

Another disadvantage is the instability of governance.

In the orc civilization, there are too many orc races, and it is difficult to say that they are of the same mind.

Therefore, once internal conflicts occur or there is any turmoil, such as a defeat in a war or the like, it is easy to start splitting, and the instability is relatively high.

After understanding this, the advantages of the one-of-a-kind model become very obvious.

That is to say, there will be basically no divisions, and the orc points used for development are definitely enough when focusing on one branch. Some high-end projects can be unlocked relatively early in the game, thereby gaining greater early advantages.

However, this unique development method is not something that every race can achieve.

First of all, there are requirements for the population reproduction ability of the race.

For example, if you take the human race, its population reproduction capacity can be said to be very low. Based on this premise, if you use a one-size-fits-all development method, you will not be able to develop on any scale even if you develop for tens or hundreds of years.

Get up, there is no time to play.

In comparison, orcs such as werewolves, kobolds, and lizardmen are all capable of following this development path.

And among the countless orc races, who is the most suitable to follow this development path?

The rat people are definitely one of them!

Unlike the vast majority of orcs, the Ratmen's population reproduction ability is very strong, even more exaggerated than humans, who are a large population.

Under this premise, due to some of the nature of the rat people, even other orc tribes that are also part of the orc civilization are extremely repulsive and even disgusted with them.

This makes the rat people become a group that can almost only develop independently in the orc civilization.

And Rose Barka is obviously a rat player!

The people who make up the rat tide in front of us now are the rat slaves, the lowest type of soldiers of the rat tribe.

The biggest feature of rat slave soldiers is that there are many, very many!

At this moment, on the battlefield of Gao Su, the second line of defense in the north, there are at least two to three million rat slave soldiers charging. This is a serious army of one million!

In Rosse Barka's rat-man empire, this kind of rat-man slave soldiers belong to the lowest level and have the largest number. It is precisely because there are so many that the food of his rat-man empire has always existed.

A big problem.

Not to mention during a war, even in normal times, the lowest level rat slaves can only eat one meal a day.

It doesn't matter if they starve to death, there are just so many of them!

But now, the all-out war with Gao Su has begun, which is actually a good thing for Rose Barca.

From the beginning of this all-out war to now, it is estimated that at least hundreds of millions of rat slaves at the bottom of their rat empire have died.

But Rose Barca didn't even frown. In recent months, he was even in a good mood because he broke through Gaosu's northern border defense line and captured the opponent's city.

The fundamental reason is that there are really too many of these rat slaves. When the number reaches a certain level, even if others don't kill him, he himself will kill hundreds or tens of millions of them every once in a while to relieve the pressure within the empire.

food pressure.

But now, he used these rat slaves who were supposed to die to break through the northern border of Gaosu, and at the same time exchanged for dozens of cities, big and small, can he be in a bad mood?
