The nests of most of the Skaven clans, especially those in the underground cities controlled by the big clans, are connected by intricate underground passages.

Centered around the "Skaven Magic Capital", these tunnels spread like a giant spider's web to almost every corner of the Warhammer world, and there is even a rat-man proverb called "all tunnels lead to rats' nests".

The origin of these tunnels is also interesting, more than 3,000 years ago, after the birth of the first nezumi "Skaven Magic Capital", after a period of development, the population began to explode, and had to find a way to expand outward.

Since the strength of the rat people was still weak at this time, and the ground was full of wandering green skins, beasts and human tribes, they chose to use the way they were best at digging tunnels to migrate and find new settlements.

At this time, some of the nezumi who studied magic created a huge machine with dimensional stones as energy underground, which was used to amplify their magic power in order to better dig tunnels.

As a result, because the nezumi technology has always been unreliable, after this machine absorbed a large number of dimensional stones, a big explosion suddenly occurred, and powerful magical energy spread all over the world through the underground.

At this time, the most loyal servant of the ancient saints, the powerful lizardman demon toad priest, happened to be using magic to change the earth's crust plate according to the will left by the disappeared master, and the two forces that were enough to destroy the world converged, causing a series of large-scale earthquakes in the entire world.

Funnily enough, these toad-like demon priests thought that the earthquake was simply caused by their own lack of control, and they didn't find the assistance of their nezumi teammates, so that their nascent race escaped the catastrophe and was able to grow stronger.

And then the worst victims of this earthquake were another race that didn't want to do it at all, the dwarves.

They had just finished their "revenge war" with the High Elves, and they were already devastated, but just after the man-made disaster, a natural disaster struck, and a sudden earthquake almost completely destroyed the interconnected underground passages between the dwarven fortresses, and the dwarven kingdoms in the mountains suddenly became isolated islands fighting on their own.

From then on, the "Golden Age" of the dwarves has officially ended, and it has come the "Age of Disaster" that can not be written with many "books of hatred".

As one of the initiators of the earthquake, the Skaven Ratmen themselves also suffered heavy losses, and the "Skaven Demon Capital" was almost razed to the ground, and some cities even sank underground, but the remaining Ratmen were pleasantly surprised to find that although the machine exploded and the nest exploded, their original purpose was also achieved.

Along with the earthquake, a large number of cracks appeared in the ground, and along these cracks, the nezumi discovered the vast network of tunnels that the dwarves had built before.

Led by the "Council of Thirteen", which was just formed after the disaster, the remaining nezumi used these dwarven tunnels as a base to spread out to the world from the "Skaven Magic Capital".

These tunnels are also the passages between the major cities of the Rat-Man Underground Kingdom today, and with thousands of years of continuous excavation, the Rat-Man can travel to any part of the world through these underground tunnels, except for the High Elf's hometown of "Ulthuan", which is thought to be floating on the sea through magical powers, and is not connected to the earth's crust.

It stands to reason that the newborn clans of the rat people usually dig new nests along this huge tunnel network, but the original "Nexus clan" is a bit special, their underground nests are not connected to the outside world, so it is obvious that these rat people should have migrated to the "steel rock" through the ground at the earliest.

Why use this extremely risky way to find new settlements?

The reason and process of this are unknown, and the stone suspects that it may be because the rat people first discovered that there are dimensional stone deposits here, and they were worried about being discovered by other rat people, so they took the lead, so they brought people over to secretly build a nest underground, secretly accumulating strength, and preparing to wait for the time to get rid of the green skin, monopolize the "steel rock", mine the dimensional stone, and then dig the underground tunnel to communicate with the rat man's tunnel network.

As for the underground tunnel, he will also arrange for the rat man to continue digging in the future, but the direction is not the tunnel network of the rat man, but it is completely connected with the underground passage of the "Iron Furnace Fort", and then the transportation between the "Iron Rock" and the territory will be convenient, you can cross the river from the ground to "Orgrimmar", and you can go underground to the "Iron Furnace Castle", and the three sides can support each other at any time.

This is very important, the tree is very popular, now it is different from the past, in the past, the "Broken Claw Tribe" was nested in the mountains and developed silently, and now it occupies the legendary fortress of "Steel Rock", I don't know how many pairs of eyes are staring, especially human shrimp, although this time I don't know why they suddenly retreated, but if nothing else, they will not let go of here.

Therefore, "Steel Rock" will still be the front line of the battle between humans and the greenskins as before, and become the most chaotic place in the border prince's territory of the "Land of Chaos", and will need the support of other strongholds in the territory at any time.

If possible, Stone would also like to ask Pesti to buy some of the famous Dimensional Stone Crushers of the "Clan Scurry", which burrows faster than rats, and is especially good for digging tunnels.

The Grinder and the Female Rat, those are the two items at the top of the Engineer's purchase list.

The general direction of the future development of the clan was determined, and the stone was also ready to rush back to the "steel rock" with all the green skins.

Now that the nezumi have been recognized by the system as a vassal race, they don't need to be guarded, so he naturally won't put his precious troops here.

Although the population of the tribe has increased greatly now, and the "Steel Rock" soldiers are strong and strong, don't forget that the "Thunder Cliff" in the north is only guarded by a few hundred goblin boys, and it is the most important barrier in the territory with the "Steel Rock" to the west and the north.

Before leaving "Disney", Stone finally emphasized the division of labor between Pesti and Gorkos, the former is called the patriarch, in fact, he doesn't have to take care of things, he only needs to concentrate on the research of dimensional stone engineering, and other trivial matters can be handed over to the latter, that is, his right claw to solve, in fact, it is nothing more than three things, mining and digging holes and farming.

As for whether Gousko can do a good job, the stone doesn't know, anyway, this rat cub didn't speak from beginning to end, he knew that he was smirking, obviously still immersed in the surprise of the carp jumping over the dragon gate, it doesn't matter, if he can't do it well, then kill and replace people, I believe that someone can do it well.
