Black Rock City, located on the 548th floor of the Abyss, is built by the gray dwarves of the Blue Castle with the black and red black stone bedrock of the Abyss, and will emit a brilliant scarlet light at night, which is called Black Rock City by the families of the Blue Castle.

Here, just after the end of a battle!

"Quick! Hurry up, hurry up! Don't let a demon go! ”

"Whoever gets hurt again! Just run a hundred laps around the Black Rock City! ”

A team of gnolls roams the lower defenses of Blackstone, stabbing the heart of a demon's corpse with a silver weapon smeared with holy water! Make sure it's dead completely!

As for holy water, it is not produced by any church, but a specialty of its own family!

Produced by the World Tree! Absolutely superb!

Due to their natural agility and agility, the Jackals are a perfect fit for their role as cleaners and reapers after the battle line.

"Let's work harder, and you can rest when you're done!"

The ogre overseer, dressed in animal skin and heavily armored outside, shouted at the magic conch in his hand!

Below, a team of tall ogres, trolls are carrying the corpses of demons densely packed on the battle line!

The demon's blood had long since dried up, and it had emitted some unpleasant stench from the passage of time, but the industrious trolls would not pay attention to these insignificant smells, and they had become accustomed to them after long hours on the battlefield.

These big men work extremely fast, some of the small demons can catch a few at a time for their big hands, and as for the large demons, there will be special goblins or gnolls to divide and transport them with tools, so they don't have to worry.

The boars are in charge of transporting the carts, driving some tame cattle to carry the work, and in the end, these demon corpses will become the fate of holy water and many other things! That is, the nutrients of the World Tree!

After passing through the battle line, the demon corpse will arrive at Blackstone City, and after being inspected by professional guards, they will take the special route in the city to reach the inner city of Blackstone City unimpeded.

Blackstone City is divided into the inner and outer city, which is designed and guided by the famous gray dwarf master, and the inner city is for living, living, trading, and city administration is basically completed in the inner city.

The outer city is mainly used for military garrisons, and the space is mainly dozens of meters below the ground.

In addition, the outer city of Black Rock City is also known as the outer urn, if the demons break through the outer defenses, then use magic to seal off the outer city, and complete the full-scale bombardment of the outer city area!

It can be described as a strategy to catch turtles in an urn!

The twin city structure of Black Rock City is very special and practical, and even at the beginning, the proposal of the outer city was made because of the cooperation of the warriors of various races, and the demons almost attacked the city all the way.

This also greatly increased the security of Blackstone City, so that some merchants were willing to come to live and trade in the inner city, and take some of the goods out of the city to make huge profits.

In addition to these demon corpses, the living demons were captured early, the iron chains with thick arms restricted their freedom, and the circles of hemp rope almost made these non-fire demons unable to move, and the fire demons such as the Fire Burning Demon were specially explained by the cold iron chain, which was extremely professional!

Some of these living demons will be sent out of Blackstone City after screening, and they will use the teleportation array to reach the outside world, becoming one of the main businesses of the Blue Castle at present: the demon slave trade!

After using the contract scroll to ensure its security, this business can be described as one of the rising star businesses on the continent of Io!

In the mining of ore veins in various countries, small wars, and even the blood sacrifice rituals of some cultists, the demonic blood has a more evil aura, which is more favored by some evil gods with special tastes, which also leads to a small number of cultists willing to secretly come to the Blue Castle to spend money and trade.

There are two ways to leave Blackstone.

The first type, the pumice stone road guarded by the elite guards of Black Rock City, is made of some small abandoned islands in Sicily, which can still be used to float after leaving the space inhabited by the Sirens, so it is used to build a heavenly road that directly connects the ground and the spatial rift in the sky! Also known as the Pumice Stone Heavenly Road!

The second is the magic teleportation array that links the two places, after accurately locating the spatial coordinates on both sides, the safety and efficiency of the teleportation array are very high, coupled with stable backup maintenance, which makes the teleportation array almost never have any safety accidents. However, because of its huge consumption of mana, the number of times it is used is not high, but as a means of retreat and auxiliary transportation in the event of an irresistible force to evacuate Black Rock City.

A team of fresh demon corpses is transported into the inner city of Blackstone City via a special transport line, and then transported to Io World by pumice stone road, with rest and intermediate stops in the air, where Siren warriors and some harpys are stationed to prevent some flying demons from attacking the convoy.

Walk through the rift of the world to the Io World, this garrison canyon of the Blue Castle.

Nowadays, with the development of this canyon, it also has a resounding name: Sealing Demon Canyon!

The meaning is simple, the canyon that seals the demons.

The original demon corpse still needed to be transported through the road all the way through, but now the root system of the World Tree extends directly here, thus growing its own World Tree Branch!

I have to say that the root system of plants is really very developed, especially for creatures like the World Tree, it is said that the World Tree of the ancient elves is completely enough to protect every corner of the forest where the elves live! The Elven Forest is enough to cover the land of the two medium-sized human kingdoms that are today! Its great strength is not terrible!

The consciousness of the World Tree can switch back and forth between these two places as easily as raising one's left hand and right hand.

In addition to these two places, other areas of Moon Bay also have branches of the World Tree, which makes it possible for the World Tree to grow wherever Terrence's territory extends today!

In the center of the Demon Sealing Canyon, in a specific area where the World Tree grows, the boar people poured the demon corpse into a very large hole, which was thousands of meters deep!

The crater is hundreds of meters in diameter, and when you look from the outside in, the inside is filled with dark red liquid, and you can see layers of scarlet and bewitching dirt on the edge of the red water, which is dyed red by the flesh and blood of unknown demons! The evil aura and the aura of the abyss inside are very strong, and just putting it in front of ordinary people for a while is enough to make some undetermined creatures go crazy and crazy!

When the excavation was first carried out, the sandworm clan from Terrence's own blue dragon mother was used to excavate and build the infrastructure, and this corpse pit could fill the corpses of tens of thousands of giant demons at one time!

It is these nutrients that make the root system and body of the World Tree grow rapidly!

At the same time, because the abyssal aura in the demon's body was intentionally eliminated by the World Tree, the bones with the highest content of abyssal aura in the demon's body, the demon horns, the demon's winged teeth, etc., the World Tree chose not to absorb them.

The first is that it is difficult to absorb, the second is that the Blue Castle needs them to be sold and used for their own use, and the third is that these things will do more harm than good after absorption, and if they cannot offset the impact of the abyss, it will be a loss-making transaction!

The flesh and blood of these demons will be melted, and the bones and other things will be fished out of the World Tree's branches and roots and placed on the edge of the pit, and then a special Blue Castle family will sort out and evaluate them accordingly to determine their whereabouts and uses.

This kind of work does not require complicated cutting at all, so that the dependents are not easily eroded and infected by the flesh and blood of the demons, and it is also more convenient and fast! There are a lot of steps and processes to dispose of demon corpses!

In addition to the corpse pit, there is also a pit in the World Tree, which is full of turquoise liquid, and just a drop exudes a rich and fragrant vitality breath! Today, the liquid has filled a whole crater, forming a sizable small lake!

This is the product of the absorption of the World Tree, with a very strong healing power, if the Holy See's holy water is synonymous with healing medicine, then these "World Tree Holy Water" are often used by the families of the Blue Castle! Therefore, it is also named holy water, saving countless lives in the Blue Fort and the surrounding area of the Blue Castle!

But today, after a cart of demon corpses fell, the waters of the lake quickly precipitated the corpses, and the branches of the World Tree beat the ground as if they were dissatisfied?

Today's World Tree seems to be a little unusual!

The person in charge of the wild boar people's transportation quickly communicated the situation to his superiors, and then, soon the chief high priest of the Blue Castle, the gnoll man's mother, rushed to the Sealing Demon Canyon overnight! The message of the World Tree is simple!

"I ..... Need to extend the body to ...... Far..... Farther into the abyss! ”
