Chechen came to the royal capital Ringerill seven years ago, and joining the royal army was a year after he arrived at the royal capital.

At that time, Nuo Yin was still a Shi Xiangchang Chief, and Chechen was assigned to her command as a new pilot. Although it was a relationship between her superiors and subordinates, Nuo Yin could not help but be attracted by Chechen's integrity. Chechen, who was born in the Great Wilderness Village, had outstanding qualities, and with Nuo Yin's careful guidance, he soon showed his talents in the Kingdom Army. After two years of service, Chechen was promoted to Shi Xiangchang Chief at a record speed and married Nuo Yin as his wife. The story about the two became a good story in the Kingdom Army for a time, and that period was also the period when the Kingdom Army was at its peak. Almost no pirates dared to make plans in the airspace around the capital.

The residents of the royal capital regarded Che Chen, who was intimidating the air thief, as a hero and loved him, but the good times did not last long.

After getting married to Nuoyin for about a year, Che Chen didn't know what he was thinking, but suddenly became silent. He seemed to be worried all day long. Although Nuoyin wanted to help him share his worries, Che Chen refused to tell her what he thought. Then one day, when Nuoyin was unprepared, Che Chen drove away from the capital on his own air cabin, leaving only a letter "I want to go to the sky world", and then never came back.

Since then, Nuoyin has been trying to find his whereabouts, but there has been no news for more than three years. Under such circumstances, Qilin suddenly came to the capital with Che Chen's letter. No wonder Nuoyin made an "impossible" response on the spot...

In the lounge of the base, Nuo Yin slowly told Qilin about Che Chen's in the royal capital. When he heard that his brother went to the sky world three years ago, Qilin fell into a long silence, Nuo Yin looked at him with some concern. Under her gaze, Qilin scratched his hair as if he was irritated, and then asked embarrassedly.

“…I want to ask, where is that ‘Sky Realm’ located?”

"Is the Sky Realm?" Nuoyin frowned slightly. Then she was not a pleasant name. "Qilin, do you know about the sky civilization and the floating city?"

"I know, I just heard someone say it." Qilin nodded.

"That's good. 'Sky Realm' refers to the high altitude of the floating city. For airships and air riders, there are all prohibited areas that cannot be approached..."

Nuoyin told Qilin about the facts about the "Sky Realm" in a cautious tone.

At the heyday of the sky civilization, the celestial people who ruled the sky built countless floating cities and floating islands in altitudes far away from the ground. Those floating islands created with high civilizations still float in the air even after the destruction of the sky civilization. A small number of them became the nests of the dragon clan, and most of them were occupied by higher monsters. The higher monsters are powerful enough to the monsters on the ground. They use floating islands as nests and draw their own territory in the air. As long as human aircraft reach the height of the floating island, they will be attacked indiscriminately.

No matter whether it is an airship or an air rider, it cannot fight against the powerful power of the "air stream" blessing of the higher monsters, let alone the dragon clan above the destruction of the sky civilization, and the dragon clan above all things is the enemy. Therefore, with the foggy clouds close to the floating city, the world is divided into two worlds: "Sky Realm" and "Overground Realm". The boundless altitude above the fog is the kingdom of the dragons, and the range of human activities is limited to a narrow space close to the ground. Whether it is trade, trade or war between countries, it must not exceed the taboo boundary.

"Che Chen is an excellent pilot, but he uses the advanced monsters in the sky world as his opponent..." Nuo Yin concluded with a dim expression. She did not say that after Che Chen disappeared, she also tried to drive the air cabin into the sky world, but was seriously injured and dying by the advanced monsters.

"But, I did receive a letter from my brother? Look, if you don't believe me, look." Nuoyin's sadness was so real. Of course, Qilin didn't doubt her words, but he was also confused. He took out the letter from Chechen from his arms and handed it to Nuoyin.

Facing the letter from Qilin, Nuoyin showed a moment of hesitation. That near-death experience and the fruitless search of the past three years made her gradually give up the slim hope, but now Qilin put the hope she had given up again in front of her. This light letter was heavier than anything for her.

Finally, Nuoyin is a rational and strong female surname. It took a few seconds to prepare for her mentally. She took a deep breath and took her husband's letter from Qilin.

"This is..." The moment I opened the letter, Nuoyin's face seemed to shine, but then she frowned, read the letter several times with a solemn look, and then shook her head in disappointment.

"Are there any problems?" Qilin confirmed.

"This is not Chechen's handwriting." Nuo Yin shook his head. "Although it is very similar to the imitation, there are still differences in the details."

"…In other words, it was someone else who used Chechen's name to call me to the capital?"

Qilin frowned. Nuoyin and Che Chen were with each other day and night, so they naturally knew her husband's handwriting better than Qilin. Since she asserted like this, there was definitely something wrong with this letter.

“But, why?”

"I don't know either, but..." Nuo Yin shook his head and read the letter again. "I think the person who called you to the capital should have something to do with Che Chen's disappearance... Qilin, can you give this letter to me for safekeeping for the time being? I want to ask someone to investigate. If it goes well, maybe you can find the clues for Che Chen." Nuo Yin sincerely asked Qilin.

"Yes, it's useless for me to hold this letter anyway... Uh, that, sister-in-law... sister-in-law? I should call you like that, right?" Qilin said hesitantly, his face also blushed.

"Ah...ah, yes, you are Chechen's younger brother, and of course my younger brother." Nuoyin also slowed down for a while before reacting, a hint of shyness flashed in his eyes, and asked, "Qilin, what are your plans next?"

"Intend?"

"Well, Chechen is not in the capital of the king, and I don't know what the person who wrote this letter is intended. If they are planning any conspiracy, you may encounter danger when you stay in the king." The green eyes showed a sincere and concerned look and suggested. "I think it is safest for you to go back to your hometown. I can arrange your itinerary for you to go back. If there is news about Chechen in the future, I will write to you immediately, so..."

"I won't go back." Qilin shook Gu and interrupted Nuo Yin's words. "It's fine if there is nothing to do. After knowing that Chechen disappeared, how could I go back to the village so leisurely?"

"That's right..." Nuoyin smiled bitterly. Qilin's reaction was reasonable, but she couldn't leave her brother-in-law alone, so she suggested: "Then come to my house, Qilin. I am Chechen's wife, and Chechen's home is naturally yours."

"Uh, don't you have to trouble like this, right?" Qilin suddenly felt embarrassed.

"You might not want to stay in a hotel or something? You don't care if you keep your sister-in-law's invitation." Nuoyin hugged her hands in front of her chest and stared at Qilin with a very courageous look.

After all, it is a woman who commands thousands of troops and is full of courage. The Qilin stared at by Nuoyin is like a kitten hunching in front of a female cat, and she can't say the word "no".

"Then...then I'll disturb you."

………………………………………

After handing over the matter of the airship to his subordinates, Nuoyin called a horse and walked towards the house with Qilin.

Although airships and other airships have long been popular in the sky, the transportation tools on the ground are still mainly animal powers such as horse and carriages. This is because airflow energy, which is powered by floating mechanisms, has the characteristic of changing the concentration in the atmosphere with height. In other words, the higher the sky, the more abundant the airflow energy in the atmosphere, and the closer it is to the ground, the less airflow energy in the atmosphere is. Therefore, it is almost impossible to drive large machinery such as airships on the ground. Based on the same principle, weapons such as machine cannons that use airflow energy are difficult to use on the ground.

While Nuoyin explained the necessity of riding a carriage to Qilin, Qilin kept looking out through the carriage window, showing an expression of excitement that could not be concealed.

The carriage slowly moved along the main street of the capital, and the Qilin was able to see the prosperous scene of the capital and deeply shocked.

In front of him, all the streets were covered with clean and neat stone slabs, and even if they ran over, they would not stir up a trace of dust. Drainage ditches were deliberately dug on both sides of the street, and the perfect facilities allowed people here to enjoy the convenience of travel on rainy days. In addition, there were various shops on both sides of the street, and the "ding dong" sound of weapons shops mixed in the aroma of the bakery. People wearing trendy clothes came and went, and the dazzling scenes made his eyes look bright.

Everything is a scale that is completely incomparable to the border towns, not to mention the Great Wilderness Village.

Although the person who pretended to send him a letter was full of suspicion, Qilin felt that there were still some places to thank him. If he had not been in the village without that letter, he would have stayed in the village, and I am afraid he would never know that there was such a wonderful world in the world in his whole life.

"...Do you think it's very strange?" Nuoyin asked with a smile.

"Well! It's completely different from what I imagined... so big! And so many!" Qilin replied excitedly. "No wonder Chechen has never returned to the village. If I weren't there, I would rather stay here."

The words of the straightforward words made Noeon smile bitterly, and at the same time he felt close to Qilin's straightforwardness, he introduced to him: "This is the Second Avenue of Linger City, which is mainly traded. You can buy goods from all over the mainland. The center of Linger City is the royal palace, and there are the Third Avenue of the industrial area, the First Avenue of the noble mansion, the Fifth Avenue where civilians live, and other places. Because Linger City was originally a city developed in the falling floating city, there are many interesting places. After dealing with the matter of the pirates, I will take you to the royal capital as a guide, my brother."

"Zombie? Is that the group I met?" Qilin's attention was immediately pulled back.

"Well, it's that air pirate group." Nuo Yin told Qilin. The name of the air pirate group is "*大大", which is a habitual criminal who has committed evil deeds. With his elusive tactics, he is domineering in the airspace near the capital. The Air Force can hardly catch their handle. This time, he was able to destroy the "*大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大大�

"Speaking of this, there is such a sign..." Qilin remembered the scene of the air pirates trying to abandon the leader and escape, and nodded in agreement with Nuoyin's opinion. "Can you deal with those air pirates?"

"Well, this is my responsibility." Nuoyin answered him. Nuoyin is Baixiangchang who commands the "Cangkong King Cavalry", and the "Cangkong King Cavalry" is originally a force responsible for the airspace security near the capital. She will deal with many aftermath incidents, including interrogating the arrested air pirates, sending troops to clear out the air pirate's nests, sorting out the incident reports, and other aftermath incidents. Therefore, she may not have the time to serve as the guide of the Qilin in a short period of time.

"It's okay, I can also wander around myself." Qilin looked out frequently, his eyes shining like a young man longing for adventure.

"That's OK, but there's one thing you need to pay attention to, Qilin." Nouyin reminded him with a smile. "I just said that the city of Ringer Ire was developed from the floating city that fell to the ground in the past. Most of the structure of the floating city is buried underground. It has now become a maze of monsters gathering, so don't get close to it casually."

"The mysterious official who gathered monsters?" Qilin was quite interested, but since Nuo Yin had warned him in advance, he would not approach him casually. "After that being said, how far is Nuo Yin's home?"

Qilin noticed that the pedestrians on the street were becoming increasingly rare, and instead they were planted with precious plants on both sides of the street. It seemed that they had already walked to another outside area.

"We have entered the First Avenue, and a little further ahead is my home." No Yin said, pointing to a building in front.

"First Avenue? Didn't you say that it was a noble mansion..." Thinking of Nuo Yin's introduction just now, Qilin looked at her as if she was startled. "Nuo Yin, are you a noble?"

"Well, my father is Duke Isere, and I am his second daughter." Noin nodded and introduced with a smile.
