From the individual flame blaster in the tunnel to the unmanned fighter found in the arsenal, the inside is all made of spells. The Flame Blaster is filled with beast crystals, which can not only directly launch spell attacks, but also the unmanned fighter is vividly displayed, with at least hundreds of spells from the inside out, and these spells operate and excite in the process, so as to generate kinetic energy, form attacks, form defenses, and so on.

This is the goblins' magic technology!

This is a unique goblin civilization!

Goblin technology may not be as brilliant as the Terrans in ancient times, but it has been improved on the basis of Terran civilization. This bold change may be beneficial, the goblin race will have to develop and study for as long as the human race, and its technological path may go longer and farther.

It's a pity that the goblin clan was destroyed once for some reason, and now the status of the mainland is not high, and it is generally equated with profiteers, liars, and thieves. In the era when Mu Yun lived, the goblins were reduced to similar characters as rat people, hiding in the forest all day long, naked, eating raw meat, gnawing tree roots, and living mediocre and uncivilized.

Mu Yun has reason to believe that the fall of the goblin civilization is related to the research of the Sky Covering Project.

Of course, such speculation is now impossible to verify.

It is not difficult to find from the situation in the armory that the evacuation of the goblins was very hasty, and two-thirds of the heavy weapons in the armory were taken away, and a part of the heavy fighters, heavy tanks, and heavy robots remained here. Mu Yun walked through more than a hundred fighter planes and continued to browse the rest of the ancient weapons.

The heavy tank, covered in jet black, has a height of two floors, is about 90 tons, and the upper part of the tank can turn 360 degrees, but there is no gun barrel installed, but there are seven or eight devices that look like inverted cauldrons. Mu Yun couldn't help but sound the flame blast gun found in the tunnel, the shape of the flame blast gun is a trumpet, and the horn mouth of the expanded shape is the place where the spell attack is formed, so these cauldron-shaped devices may be spell firing specialty.

Mu Yun continued to admire the ancient weapons.

Rows of 10-meter-high heavy robots are lined up in front of you, heads, limbs, torso, robots are very similar to the structure of the human body, the knees are specially designed with a structure, and when you kneel down, the legs will become a tracked chariot, and the structure of various complex weapons is very complete. In addition, there are several types of heavy robots, including one robot with eight legs, which resembles a super-large metal spider monster, or a monster that looks like a praying mantis.

These big guys appear on the battlefield, and any one of them can sweep through an entire army.

Qin Yuemei's eyes showed a look of yearning: "What if...... If we can master these ancient weapons, the entire Northern Continent will probably be fearless!"

Mu Yun had to admit the power of the goblin weapon, and at the same time frowned and said, "I think that the ancient weapon will always sleep, so it's better not to wake up." Because otherwise, no matter who gets it, there is a danger that the stability of the northern continent will be broken, and it will eventually fall into a situation of frequent civil wars. ”

Qin Yue smiled and said, "Actually, even if they are dug out, what can they do? These ancient weapons are too high-level, the Nalan family's technology may still be able to study a thing or two, and even if the rest of the forces get it, what is the use?

Mu Yun thought about it and thought it was too.

Ancient weapons are far ahead of the contemporary, and they cannot be dug up and put into use.

"What about the others?"

"Jin Mu, Yuntian, and Lei Yi all became very excited after the earth masters discovered the armory. However, heavy weapons cannot go out through the laboratory, and if these large weapons appear here, then there must be an exclusive transportation channel, and there is a way to go directly to the outside world. The three of them had already gone to look for the passage, and by the way, they were looking around to see if there were any simpler light weapons or individual weapons. ”

No matter how powerful the ancient weapons in the secret realm are, and how rich the environment in the secret realm of Wuluen is, only those who succeed in conquering the secret realm can enjoy everything here. The three of them were not burned by the discovery in front of them, and immediately looked for the exit, looking for the core area of the secret realm.

The Biological Research Institute is definitely a key area of the Secret Realm,

Only by finding a way to find the core area, seize the control center of the entire secret realm, and freely master the opening and closing functions of the secret realm and the various defense systems in the secret realm, can it be regarded as completely occupying the secret realm.

Mu Yun didn't continue to observe, and carried hundreds of storage crystal plates and storage scrolls back to the others.

Most of the corpse of the Heaven Covering Beast has been divided, a large number of bones have been removed, and several of the most critical parts have been divided by everyone. The little Heaven Covering Beast was even more jaw-dropping, and it actually swallowed several tons of flesh and bone of the Big Heaven Covering Beast, the speed was staggering, but the small body did not grow at all.

The little Heaven-Covering Beast seemed to have eaten enough.

When he saw Mu Yun coming back with a lot of things, the little Heaven Covering Beast went directly to meet him, and when the others were not paying attention, he suddenly opened his mouth, spit out a few bones in his little mouth, and held it with his claws and stuffed it to Mu Yun.

"It's ......"

A few bones are as crystal as jade, although they are not the treasure bones of the engraved skills, they are taken from the most essential parts of the backbone of the Heaven Covering Beast, which contains the essence of the Heaven Covering Beast, the little Heaven Covering Beast is kind, Mu Yun of course smiled.

"I see, your body has its own space?"

It's no wonder that it can swallow so many things, and the body of the Heaven Covering Beast has its own space, like a storage bag, because compared with the fear of natural space, the space generated by this artificial or special method is often unsound, and can only store things in material form, and things in pure energy form, such as spirit and soul, cannot enter. Therefore, this space can only hold dead things, not living things.

Hence the name storage space.

The space in the body of the Sky Covering Beast is not only large, but if the space is large enough, wouldn't it be able to carry a few heavy weapons away?

The little Heaven Covering Beast sensed Mu Yun's thoughts, and immediately transmitted a thought to him.

Mu Yun knew that the space in the body of the little Heaven Covering Beast was about five hundred cubic meters, so he had to helplessly dismiss the idea, five hundred cubic meters was indeed not small, but if he wanted to hit a fighter or tank into it, it was obviously not enough. This Sky Covering Beast was only a few hours old, and Mu Yun estimated that after the Sky Covering Beast grew up, the space in its body would also increase exponentially.

Mu Yun handed over all the things brought out of the database to the Heaven Covering Beast for storage.

This is a large number of engrams, which contain a large amount of biological information and technology, although it is not known what it is used for, but the data and information of the goblin clan are actually ordinary things?

About ten minutes have passed.

Jin Mu, Yun Tian, and Lei Yi came back, and the three of them looked for the road in front of the armory, and they really found a different door, 20 meters high and 10 meters wide, the door was built in a large hall, and what was strange was that if you look at it from the outside, there is nothing on the back of the main hall and there is no way to remove it. Therefore, several people judged that this was a spell door, or a space door,

The entire research site is about one or two hundred meters underground, and the weapons of the armory can only be transported out through an exclusive special passage.

Mu Yun's gaze swept over the spell gate: "Is there a way to activate it?"

Kaneki replied, "It shouldn't be difficult!"

Not far from the giant gate, there is a 2-meter-high spar pillar, which is inserted into a huge magic circle, if I am not mistaken, this pillar is the key to opening the magic circle. Jin Mu injected mana into the pillar, and the magic circle on the ground suddenly lit up one by one, and then the door opened.

This is indeed a spell gate.

Everyone walked through the glowing door one by one, only to feel a strong light attribute energy sweeping through the body, although it was not very strong, but if there were demon creatures, if they wanted to escape from here, they would definitely be burned, and at the same time cause an alarm.

Mu Yun put a protective talisman on the little Heaven Covering Beast.

Although the little sky-covering beast has a strong dark nature, but the body is a dragon after all, and the dragon clan is a relatively positive creature, plus it has the protection of Mu Yun, so it can completely pass through the spell gate.

When Mu Yun took the little Sky Covering Beast through the spell gate,

The ambient temperature suddenly cooled a lot.

Mu Yun raised his head and saw the blue sky, his mood was suddenly much more comfortable, the underground world hundreds of meters deep, the environmental atmosphere was very depressing, and he suddenly returned to the surface, naturally relaxed and comfortable.

Qin Yue looked around left and right: "This seems to be a big square......

Under the blue sky and white clouds, there is a huge square, although after nearly 20,000 years, the ground is still clean and clean, and no weeds have grown. There are a large number of ancient weapons moored throughout the site, including warplanes and tanks, plus some fortress batteries, etc., all in all, the defense is strong.

After 20,000 years, this place can still remain unchanged, and the main reason is a layer barrier.

If you take a flying machine and look down at the earth from a high altitude, then it is not difficult to find that the entire square is circular, just covered by a huge barrier, and the shape of the barrier is like an inverted giant bowl, and the barrier has a super defensive effect, and at the same time it is not internal to the outside.

Outside substances can't come in.

But the matter inside can go out.

Mu Yun observed the nearby terrain, surrounded by mountains and mountains, the entire square was built in a sunken basin, but the altitude was very high, basically there was no way to enter, and he could only come from the Heaven Covering Beast Research Institute, which was enough to show the secrecy of this place.

"Ah, there are giants!"

Qin Yue found that in the center of the square, there was a majestic palace, and outside the palace stood a row of thirty-meter-high giants, each wearing gold armor and holding a heavy giant hammer, looking like they were sworn to defend the palace.

"Don't be afraid, these giants are long dead!"

Mu Yun had seen this kind of guardian giant in the Eternal Mausoleum, most of them were super guards created by goblin biotechnology, very loyal, mentally retarded, and infertile, so many years have passed, although they are still standing here, they have actually died a long time ago.

After Kaneki understood the matter of protecting the giant, he couldn't help but be a little amazed, "This palace is so well guarded, it's very unusual, let's go in and have a look." ”
