Seeing the extremely shocked expressions of several people, the old dirty ghost explained triumphantly: "These are all opened up many years ago when the demon clan invaded, and they were opened up by our ancestors to form such a huge space. ”

"Demon invasion!? Could it be that the rumors were true?"

The words of the old dirty ghost shocked several people.

This time, he was curious for a while, and secretly followed the old dirty ghost, but he didn't expect it to cause extreme shock to several people one after another. This exploration is really worth it, not to mention anything else, just these things are what you have seen and heard, it is a once-in-a-lifetime opportunity.

"Of course it's true. The old dirty ghost glared at him, and said proudly: "Our races that stayed here are the guardians who volunteered to stay after defeating the demon clan many years ago. ”

"These!?" Jiang Feng was stunned when he heard this: "Are you saying that in addition to you goblins, there are other races living in this underground?"

The old dirty ghost glanced around at everyone contemptuously, and said coawardly: "Of course, this underground world is a real world, not only with a variety of races, but also with national cities, and there is no difference from the surface world. ”

"How is this possible?" Jiang Feng wondered, "I have also lived in this continent for many years, how come I have never heard anything about your underground world. ”

The old dirty ghost bared his teeth and smiled: "That's because we had agreements with all the forces on this continent at the beginning. No surface force is allowed to enter our underground world without the permission of the people of our underground world, let alone reveal information about this place. ”

"Why?"

"Because of our contribution to this world! Because it is the protection of our underground races that keeps the peace of the entire continent and even the entire monastic world. Who are you preparing for that teleportation array? This is what the world owes us!"

The old dirty ghost's words are righteous and awe-inspiring, and they are really heroic.

"Isn't the Demon Realm Passage sealed yet?" Jiang Feng exclaimed.

The old dirty ghost sighed and said, "Alas~ To say that the great sage back then did use boundless mana to seal the main entrance of the demon world.

However, some small entrances still exist, but fortunately, these entrances cannot withstand the entry of high-level demons, so they will not cause major harm to our Dao realm.

However, some demon cubs can still sneak over and attack and destroy. We, the underground guardians, are guarding everywhere to prevent these scattered demon invasions.

In fact, the war against the demons has never ended, it exists in another way and continues to this day. ”

"Why? If you can seal the main entrance, why don't you seal it all together, once and for all?"

Who knew that the old dirty ghost was also at a loss, shook his head and said: "I don't know about this, it is said that this is the great sage who did this on purpose, it should have another deep meaning, right?"

"Oh~!, what is the deep meaning?"

"Air Combat Garrison Guard Team 4, see Elder Lin Si, welcome the Elder back safely! These are all the Elder Guests?"

Jiang Feng was asking to himself, and was startled by the sudden voice.

Looking at the voice, I saw more than a dozen people appear out of thin air above my head. Each of these people flapped their metal wings like the old dirty ghosts, and they held all sorts of strange magic weapons in their hands.

At the same time, a patrol in the distance was rapidly approaching. These people are even stranger, each of them is inside a giant golem, controlling the puppet and doing many actions that humans can't do.

In the scene in front of him, Yu Mu seemed to see the figure of Gundam in his previous life. The goblin clan is clearly using a civilization technology, similar to a fusion of Earth civilization and the monastic world.

The giant puppet approached, and everyone felt the huge coercion exuded by these big guys.

Each of these puppets was more than five meters tall, and the highest had reached more than ten meters. The entire body is made of unknown metal materials, and its hands and feet are bound with magic weapons, which, combined with its flexible mobility, is like a transformer.

The tallest puppet at the head walked up to the old dirty ghost and said, "The Seventh Army Garrison Guard Team has been ordered to come and escort Elder Lin and all the guests. ”

The slightly harsh metallic sound, hoarse and low, buzzing and terrifying. When everyone heard this, they were all shocked, this puppet can actually speak!?

It turns out that the old guy's name is Lin Si! That's what everyone thinks.

The escort team of heaven and earth will protect the group in it. said that it was an escort, I'm afraid it was mostly a surveillance component, and, obviously, people had already discovered that they were coming.

Follow the escort to the goblin habitat.

As far as the eye can see, in the periphery of the tribe, although there is no city wall, there are metal iron pillars more than 100 meters high one after another. Behind these pillars, there are also wheeled cylindrical objects arranged one after another.

These wheeled barrel-shaped artifacts, I'm afraid that only Yu Mu can vaguely guess its usefulness here, because the appearance of these things is clearly a cannon.

As for those metal pillars, I don't know what they are used for, but I don't know if I don't ask, these facilities must be some kind of protective weapons.

What made Yu Mu feel strange was that the goblins were so advanced in science and technology, but the places they lived in were extremely primitive, and they were still living in the way of life of primitive tribes.

Stone huts form communities. One by one, the communities dispersed and formed a tribal whole. This group is living in its most primitive state, developing separately but interdependently.

Only in the center of the tribe are a few tall buildings, but they are so magnificent that they seem to be out of place in the original state of the surroundings.

The convoy did take them to the outermost part of the area to settle down, which was very far from the core area, and even some distance from the goblins' living quarters.

There was only a team of guards who accompanied them here, and even Elder Lin Si also returned to the clan after arranging for them.

If you come here, you will be safe! I think the goblins will not be hacked because of this debt.

The environment in which a few people live is certainly not much better, it is the most ordinary kind of small stone house. The living conditions are tolerable, but the most intolerable thing is the goblin food.

They actually eat all kinds of underground bugs as their main food, and they seem to enjoy it very much. Especially when An Shu saw these 'delicacies' that were still squirming, his face immediately turned green.

Fortunately, everyone brought their own dry food, ate some briefly, and went to rest. Lin Si didn't show up again this night, probably because he had been away from home for too long and had too many things to report to the clansmen, and Yu Mu didn't care about them.

Anyway, the purpose of their trip was to stay here for as long as possible, because they had other ideas.

In the middle of the night, several people who were doing their own work heard a tsunami-like roar of beasts at the same time. Then there was a roar and a great earthquake, and it seemed that the earth was trembling.

Several people left the room almost at the same time.

When I went out, I couldn't help but be shocked.

The beast tide is coming!

In front of everyone's eyes, there was an overwhelming field of wild beasts, swarming towards the camp.

Yu Mu and the others couldn't help but change their color, but the goblin guards were already in full array, and more guards were coming from all directions. These people are busy but not chaotic, anxious but not panicked, obviously used to this kind of formation.

"Demon... Beast!" was the first to exclaim.

The first approaching group of flying beasts, as soon as these demonic beasts entered the goblin airspace, there was a roar above the dome, and beams of light, like rain, instantly shot down most of the invading enemies.

Immediately after, countless disc-shaped flying machines flew down from the sky in dense clusters, shooting out Dao Light Blades and shooting the remaining flying demonic beasts.

"Wow~ This... This is too fantastic, they actually have drones!" Yu Mu couldn't help but exclaim.

"What is a drone?" Jiang Feng asked curiously.

"Uh~ It's nothing, it's just a temporary idea, and it's just a random scream. ”

Jiang Feng didn't doubt him, nodded and said, "I didn't expect that the goblin's flying magic weapon has reached this level, and it can fight independently with just runes, it's amazing!"

"Runes, you're saying that this skill is the effect of runes?"

"Hmm~" Jiang Feng nodded and said, "Yes, my master also has research in this area, but he has not achieved such achievements." The goblin clan is worthy of being born alchemists, and it really lives up to its reputation. ”
