The hideout where Biliss was placed was underground.

It is a chain of caves hidden ten meters underground, which contains a prison for prisoners, a warehouse for storing war spoils, but more often than not, a temporary insect nursery room.

Because the vent is too hidden, the air circulation in the cave is not very good. In addition, cultivating war insects requires a large amount of fresh blood food, so as soon as he entered, Grim felt the foul and fishy smell of the air inside the cave.

Bilisi is a worm witch who has transformed into an undead worm himself, so he is not as indispensable to things like air, water, and food as he is to the human body. As a result, Bilisy is almost insensitive to the harsh environment of his residence.

However, he didn't care, but the goblin prisoners in prison couldn't.

In such an environment with little food and clothing, and humid and stuffy air, all the slightly weaker goblins will die in the shortest possible time, and the rest are extremely strong individuals. Unfortunately, the mass death of goblin prisoners of war still did not cause any concern for Bilis.

Dead goblins are thrown into the hive to become food for the evolution of the larvae, and nothing is wasted. If the blood food reserve is too low, then go to the goblin colony and loot some more, there are many of them anyway. Therefore, he never had to worry about the reduction of blood food, and he would not consider improving the living conditions of the captives so that they could live longer.

Of course, different levels of captives also enjoy different levels of treatment, and those few who are also well-known among the goblins were singled out by him and kept in solitary confinement in the 'Yahao'. Even in order to avoid their premature death, Billis also selected a few mother goblins to serve them.

This included a high-ranking goblin engineer, two repairmen, and two lower-ranking officers of the Seventh Marine Corps that he had captured in the small town of Beta.

Under Bilis's torture, these goblins also revealed some information one after another. However, their knowledge is limited, and the information they provide is even more fragmented, making it difficult to peek into the true secrets of this great goblin empire.

So Bilisy never disposed of them, just waiting for the arrival of their master before deciding their fate.

Grimm greatly appreciated Bilis's rigor, and interrogated the goblins one by one from the first moment he arrived in the secret cave.

It can be seen that during the time they were locked up in the secret cave, these goblins suffered the greatest and most terrifying horror in their lives. Every day, you can see and hear slaves of all races being taken out of their prisons and thrown into the horrible hives that fill the mound of death.

The mournful wails of the slaves before they died and the sound of the larvae chirping and gnawing at the flesh and bones almost never stopped, lingering in their ears at all times. Although they can't see the picture of the larvae eating, what they hear and smell can stir their minds even more.

Every day he watched his companion being dragged away and never turned back, every day he listened to the terrifying sound of chirping, and every day he sniffed and inhaled the foul air with a strong smell of blood and acid rotting corpse liquid...... No goblin can endure such an environment.

Many goblins were not starved or suffocated at all, but were scared to death by this terrifying atmosphere!

Therefore, when Grim interrogated these goblin nobles, he found that they spoke incoherently and looked crazy, and even if Grim mastered the lingua franca of this plane goblin through witchcraft, he could barely understand what they were saying.

However, unlike Billis, Grim doesn't really care about the so-called top secrets. He did not inquire about the origin of the magic energy battery, nor did he ask about the internal secrets of the magic energy mecha, but repeatedly interrogated the daily life of some goblins and the ruling structure of the goblin empire, as well as the basic way in which the country and army operated.

Although these things are trivial and too fragmented, they are of great benefit to the operation system of the entire goblin plane that Grim splices and outlines. I am not afraid that the information is too trivial and messy, because under the guidance of the chip, every question asked by Grim is the core node of the construction of the goblin plane operation system.

And these are usually well-known universal common sense and humanistic ideologies, and almost never any goblins regard them as high-level secrets related to the existence of the goblin plane.

Therefore, when one by one the information was turned into data and information flowed into his brain, the strange elite empire that was originally clouded and foggy slowly showed its basic outline.

However, it is a pity that the number of goblins here is still smaller, so most of the outlines of this goblin empire are still in the fog, and they can only slowly deduce the possible situation of its core information through the vague information of a lin's and a half.

The so-called magic energy battery Grim has also been identified, and it does belong to an energy application system that is completely different from that of the wizarding world. However, in it, Grim still found a trace of déjà vu, elementary rune literature!

In the Knight Plane, the natives there were able to invent a rune that combined the energy of the magic crystal with their own life energy to create a unique advanced system of demon hunters. Of course, there is also the impetus behind the dragons.

And in this goblin plane, the cowardly little goblin actually relied on the accumulation of knowledge and technology to invent a relatively primitive goblin musket. This made them initially get rid of the identity of a weak race and become the top ten intelligent races in this plane.

And what makes the goblins completely stand out and overwhelm other races to become the dominant power of the plane is the birth of magic weapons!

The early magic machines were simple and crude half-metal golems, powered by a scarce number of magic stones in the plane. The energy inside is released by burning the stone, which drives the steam device, which drives the mechanical gears that allow the big men to move.

Of course, there are many problems with this method, so the early magic machines were slow and stupid, and the technology was so simple and crude that it was impossible to look at directly. But with such primitive magic weapons, supplemented by an incredible number of muskets, the goblins have established themselves as children of the plane.

Although the goblin plane is low-magic, there may still be some natural magic stones in some local environments. Therefore, the goblins used their powerful magic weapons to defeat one strong clan after another, and then forcibly enslaved them to open mines for themselves, dig metal ores, and dig up those rare magic stones.

As for the appearance of the magic energy battery, it has been a matter of nearly a hundred years, and some engineers of the Goblin Empire seem to have received the guidance of some mysterious people outside the world, and even applied some of the occult knowledge they have gained to magic weapons.

As a result, the Goblin Empire built a huge space furnace near the national capital, which can continuously draw magical energy from the dimensional void and encapsulate it into some special crystal prisms. And this is the origin of these magic energy batteries in Grim's hands.

Although the energy of these magic energy batteries is too rough and wild, and it is much more dangerous than the magic stones, there is no limit to the number of them. Therefore, with the magic energy battery, the goblin empire got rid of its dependence on magic stones, thus allowing the goblin clan to have an inexhaustible source of energy.

And with the advent of the magic energy battery, more and more new weapons and equipment related to it have begun to appear in the Goblin Empire, and the overall strength is rising at an unprecedented rate. However, the Seventh Marine Regiment that Grim has been in contact with is still a local garrison, so it has not been equipped with the latest magical energy.

Truth be told, the more the goblins heard, the more Grim had a sense of foreboding.

Especially when the senior goblin engineer named Beirut drew the engineering sketch of the magic mecha on paper, Grim's foreboding was even more extreme. In the process of storing magical energy, absorbing magical energy, and using magical energy in the Great Goblin Empire, Grim has seen too many things that are the same or similar to the witchcraft runes.

This undoubtedly made him can't help but start thinking about it.

You must know that two completely different worlds, without interconnected channels, it is impossible for the exact same magic runes to appear.

In the case of the knightly plane runes that Grim once obtained, although the runes representing flames are the same or similar in function as the fire runes in the wizarding world, they are completely different in terms of rune writing. The runes of each world exist in the form of a form that conforms to the laws of the plane.

Therefore, the laws of the plane are different, and the runes embodied by the laws are also different!

However, in the engineering sketches sketched in Beirut, Grim saw too many runes from the wizarding world. Although they have all been artificially distorted slightly, many of the iconic Origin symbols are still there, and they are so clear.

Especially when Grim heard that Beirut talk about Prince Ghazruvi, the 'father of magical energy' of the Goblin Empire, in a tone of super admiration and admiration, his face couldn't help but twitch a little.

Gazruvi ...... Gazruvi ...... Gazruvi ......

Who could be more recognizable and familiar with this name than Grim?

The reason why he was able to break into here with Bilis and Mary was because of the work of the 'Grand Duke' of Gazruvi. No, it is no longer a Grand Duke, but the noblest and greatest goblin engineer, alchemist, and inventor of the Goblin Empire, and the only prince of the Goblin Empire who does not have royal blood.

According to legend, this goblin prince suddenly invented these magical runes that could change the fate of the goblin empire with his own brilliant mind. If it weren't for the tradition of the goblins, only the royal blood could ascend to the throne of the king, otherwise it would be unknown if this Ghazruvi would be able to become the great lord of the goblins.

Damn it...... Damn it...... Damn it......

Grimm asked Billis to bring the goblins back down, while he himself wandered restlessly back and forth in the cramped crypt.

At this moment, he vaguely understood why, after being promoted to a wizard, the wizarding code issued by the Wizarding Association listed exchanging knowledge with the heterogeneous plane as the top taboo. In the past, he was 'young and ignorant', and he only knew that elementary runes belonged to the basic knowledge of rotten streets in the wizarding world, and it was not a top secret.

That's why there was a 'fair' exchange with that Ghazruvi through Kabi.

At that time, it seemed that this kind of exchange was undoubtedly a 'big advantage' on their side, but now it seems that it is really stupid!

And more importantly, he actually created a big problem for himself 70 years ago 70 years later!

Super big big trouble!
