St. Pysburg, located in the northwest of the Slovean Kingdom, stretching for thousands of miles in the Pis Mountains, is the base camp of the Josim family, and the family status is above the field crystal mine.

There is a word "castle" in the name, but this is not a simple castle, but a mountain city built on the mountain, connecting many mountains and mineral veins, and it is a large-scale and impregnable mountain city.

Although the huge barrier created by the Guardian Stone still exists, the low temperature in this mountain castle can still reach close to minus 50 degrees Celsius, which is extremely cold.

Sent into Fort St. Pyss by fireflies using the power of the teleportation pod, in the midst of the fierce snowstorm, Leon and the other five were quickly walking through a steep mountain road at this time.

"Ah, it's not good, Shenlong One's left front foot is stuck!"

Several people were leaning over and hurrying, and suddenly Xiaobei's voice came from behind.

Jumping into a body more than two meters tall, the shape is quite simple and sophisticated, four legs on the ground, four arms two large and two small, carrying an oval storage box exoskeleton reinforced armor close to the front.

Without saying a word, he smashed a frozen rock with one foot, and the reinforced armor shook slightly in the cold wind and snow, and finally stabilized himself after emitting a few white smokes.

"Hey, how's it going, can this guy still move?" asked a red shadow through the wind and snow, landing like a civet on the shoulders of the armor, pressing the hat to block out some of the wind and snow.

"It's okay, I was just accidentally stuck just now, and sure enough, actual combat is the best stage to test the quality, it seems that this guy has a lot to improve. In the strengthened armor body with the four big characters "Shenlong No. 1" written in wild grass like a dragon flying like a phoenix on the left shoulder, Xiaobei, a raccoon who was being fine-tuned, said quite calmly.

"You're too stupid on this kind of mountain road, didn't you add a flight function when you designed it? As long as you install the Sky Stone and connect the power source composed of the Philosopher's Stone and the Energy Crystal, it shouldn't be a problem, right?"

Coming to the exoskeleton reinforced armor controlled by Xiaobei, it was the cold winter who spoke. I saw that others were more or less wrapped in layers of winter clothes at this time, but this one was still wearing a green robe and a white robe, with a jade belt with the wind, and the image of a handsome boy who wanted to be demeanor and not temperature, from top to bottom, it was just an extra dark blue cotton scarf around his neck.

"You're right, I made a jetpack when I designed it. ”

"Hmph, why don't you install it quickly?" Li Ang said casually, and glanced around.

The howl of the wind was like a ghost crying god, which made the heart palpitate. Cold flakes of snow swept across his face like blades, and the surrounding vision was dim, and there was no movement except for the sound of the wind and snow dancing.

"It seems that there is a loophole in the effective range of the cold-resistant inscription, and the mechanism that controls the storage backpack is frozen, so you can only rely on manual attachment if you want to add a plug-in. ”

Listening to that Xiaobei's tone, it was quite helpless.

Don't look at the fact that he studied art in a restaurant, and he didn't leave the "Shenlong Ji" in his life and work, but this raccoon man who can understand people's hearts is still born with the heart of an inventor.

Fascinated by goblin technology and oriental puppetry, he spent almost all of his spare time studying and working on invention and manufacturing, especially various mecha armaments. Coupled with the power of his dragon soul and ingenuity, he has even touched the threshold of "artificial intelligence".

"How's it going, can you go?" Karene Josim asked aloud in the wind and snow on the back of a Pyth yak frozen in ice, dressed in a cotton armor winter coat with black lines on a red background. At this time, the girl's heart was more anxious than anyone else.

The personnel participating in this operation are the same as originally planned, namely Li Ang, Feng Shuang'er, Raccoon Xiaobei, Rindong, and the five people who served as guides.

Feng Shuang'er and Kalian are both "fire", and cold winter is "ice", Li Ang, who wears the cold ring and warm yang spirit bead that Xiao Ling got from the cultivation cabin, is naturally not afraid of wind and snow, and as for the raccoon Xiaobei, for some purpose, Li Ang must take him with him.

"Wait a minute, right away. ”

After answering Kalian, under the guidance of Xiaobei's heart, Li Ang opened the oval storage backpack behind the "Shenlong No. 1" with his bare hands. Find and take out a metal ball with a pair of wings marked, press it on the back of the backpack, press the mechanism button, and with a "click", the metal ball actually turns into a pair of wings.

With a flash of spiritual light, as the elements between the Sky Stone and the Energy Crystal and the Magic Stone penetrated, several small blue tongues of fire erupted, and Xiao Bei manipulated the Shenlong One he built with his own hands to really fly.

"Miss Feng, can you stand on that shoulder?" Feng Shuang'er was about to jump off the armored shoulder, when Li Ang suddenly asked loudly.

"No problem, do you want me to stay and protect him?"

"That's right, that guy is important, thank you. After shouting goodbye to Feng Shuang'er, Li Ang hurriedly said to Xiaobei: "Don't fly too fast, follow us." ”

"Got it, don't worry, Leon, I won't do anything risky. Xiaobei understood and spoke in his heart.

"Okay, let's go, see that fortress in front of you? Climb up to the fortress and you'll see the central castle!"

In this way, under the guidance of Karen, everyone quickly entered the Fire Elf Fortress, which was already half lifeless in the fortress built on a hill.

From the moment you enter the fortress, you can see the traces of battle everywhere, and the battle-damaged mechs firmly sealed in the ice and the mountain chariots on the side of the road are like ice sculptures.

The ruined walls and fortifications were still rolling up ice crystal fragments with the strong wind, falling into the snow, and the dead soldiers and mages did not have a complete corpse, and the broken bones of the corpses flashed with terrifying ice crystals in the cold wind, which was terrifying.

"It seems to be a one-sided massacre. Looking around at the tragic scene, Rin Dong muttered.

Hearing Winter's voice, Karen didn't speak, and flew up a magical tower with half of the top missing.

"How's it going, is there anything unusual around?" Near the tower, Li Ang asked in a whisper to Xiaobei.

Flying around this small fortress at low altitude, Xiao Bei and Feng Shuang'er didn't find anything special.

At this moment, the Noah, which has returned to Sky City, is being recharged. Because one is in an open world and the other is in an enclosed space, Leon and Firefly are in two different planes that completely overlap each other. Therefore, Firefly can't give Leon all kinds of assistance like he does outside, and the only thing he can do is still be able to communicate with his master.

"The hosts. ”

"What's the matter, tell me. As soon as he walked into the Magic Tower, Leon suddenly heard the voice of Firefly's heart.

"Structural scans of two unidentified metal spheres have been completed. ”

"Okay, it's worthy of being my good firefly, how about it, what did you find?" Li Ang was overjoyed when he heard this.

In order to find out the origin of those monsters, Leon and the others brought back three metal balls that had been firmly frozen in the winter during the battle in the underground warehouse of the fortress on the side of Mount Pis. One of them was given to Harlant, and the other two were secretly placed in the safety of the Noah by Leon, where they were guarded by Celroso and Gremira.

"As the owner said, both samples have extremely sensitive self-detonation procedures, and if they are destroyed by external forces or disassembly methods, they will self-expose and destroy all information. ”

"Got it, so did you scan it as a whole?"

"Yes, master, after a complete full-structure perspective scan, it can already be preliminarily determined that they are scientific and technological products from the earth. ”

"What did you say?"

Firefly's speed of speech was still unhurried, and his voice was still so serious, but Li Ang, who heard this information, was shocked for a moment, and his body trembled involuntarily, and his eyes widened.

"According to the micro-carved text on the side of the core component inside the sphere, it can be judged that this metal sphere is from the 'National Universe Union'. ”

"Guoyulian, is the 'International Space Joint Exploration and Development Organization', which is jointly formed by more than 100 countries around the world and wants to engage in extraterrestrial immigration under the banner of exploring the universe?"

Surprised, Leon deliberately said the message in as much detail as possible, and at this time, not only was he no longer confused, but a bold idea suddenly popped into his mind......
