The flying warship was one of the battle weapons of the arcane empire, used for their expedition through the multiverse.
If one was to say the floating city was a transcendent battle castle that was unrivaled in the planes, the flying warship was the space castle that arcanists used to move unhindered in the multiverse.
Each flying warship represented the pinnacle wisdom of the arcanist empire.
The arcanist empire had very strict management with regard to their flying warships. It was very rare for a situation like losing a flying warship to appear.
Even in the current Puluo World, the remains of a flying warship would be monopolized by powerful mages. They had attitudes of reverence when they researched these remains, as these remains still contained pieces of unparalleled wisdom.
Xu Nan had no idea where this flying ship came from. He only knew its name was Fireflow and was a flying warship of the white-dragon grade.
The mechanical voice should be from the warship's soul. It had been traveling in chaotic space for too many years. Back then, even the spellcasters of this warship had given up on it. For countless years, Fireflow traveled through outer space and finally managed to arrive here for some reason.
It was a pity that the damages to the warship were too severe. It was almost impossible for it to be restored back to its original state.
This group of people was originally extremely curious at the start. They even ran into the warship to blindly wander around.
Xu Nan gave them access to enter the flying warship. He himself then headed to the control room to research the mechanisms there.
Not long later, the flying warship Fireflow soon sank into a deep sleep.
Xu Nan glanced at the complex machinery and runes in the control room. He was completely clueless.
After all, it was a representation of the arcanist empire's peak intelligence. If Lu Junyi was a level 15 industry mage or above, Xu Nan felt he might really have the ambition to start repairing the warship.
But now...let's forget about it.
He was only thinking about how he should maximize the use of this flying warship that he obtained unexpectedly.
"If I didn't remember wrongly, Fireflow said that the Lost Paradise and Arcanist Empire were allies. If not, I would have no way to gain the temporary control authority. Wait a minute…"
Xu Nan's eyes brightened. He turned the system's Lost Paradise Exchange Market on!"
He searched for contents that had a connection with the arcanist empire and flying warships.
After a while, he managed to find a book named [Arcanist Empire Flying Warship Operation and Maintenance Manual (general version)]!
It was unclear who the author was. According to the style of Ron Warlocks, it wasn't difficult to guess that this book must be written by some shameless warlock who stole the IP rights of the arcanist empire.
The price of this book wasn't expensive. Most probably, the owner also felt that it would be incredible if someone still wanted to learn how to operate a flying warship in the current era.
Xu Nan immediately used 700 ever-gold coins to purchase this book.
The manual swiftly appeared in his inventory. Although it was said to be a manual, it was actually a very thick book. Just the introduction and illustrations caused Xu Nan to feel a headache.
However, for the sake of benefits, Xu Nan gritted his teeth and continued reading.
Without realizing it, time flowed by.
When he had roughly read through the entire book, it was already the next afternoon.
The situation in the underground city could still be considered peaceful. The initial uproar caused among the imps by the appearance of the flying warship had been suppressed skillfully by Soupy.
The imps curiously surrounded it.
Xu Nan's heart stirred.
He ran to the power room and took out the original energy source. It was an exhausted energy block.
After that, he placed the sealed great demon heart into it.
In the power furnace, a bright green radiance flashed. The great demon heart trembled a little as though it was unwilling to become the energy source of the flying warship just like that. However, the powerful sealing spells and energy guiding formation in the power room put an end to any possibilities of an unexpected situation.
"It's actually useful."
"The manual stated that there are two forms to the flying warship - the warship form and the foundation base form. Regardless of the situation, even if the flying warship's systems are destroyed. As long as there's sufficient energy, it would be able to transform into the foundation base form. If that is true, wouldn't it be able to become the embryonic form of the underground city?"
Xu Nan grew increasingly excited as he thought about it. He then ran back to the control room.
Seemingly because of the great demon heart, Fireflow (the ship's spirit) gradually awakened, and a few monitoring scenes appeared.
Xu Nan could see that in a certain room, Lu Junyi was helping Shi Fanglin cut his nails.
After cutting the nails, the two of them glanced at each other.
Shi Fanglin: "How does becoming a job-holder feel like?"
Lu Junyi shook his head. "I don't know...why don't you wait a little more. Do you feel anything strange?"
Shi Fanglin fell silent for a long while before revealing a determined expression.
"I think...let's go ahead with the appendix removal surgery."
In another room, Qin Lele was snoring loudly in her sleep, and Gu Xiaomeng sat down in the room next to it, praying silently. Her body emitted a beautiful divine glow.
There were many rooms in the flying warship, and the facilities also didn't show any signs of severe degradation. They were like ready-made shelters.
"Good afternoon." Fireflow's voice rang out. "Thank you for helping me change the energy source. As a temporary access controller, before a higher authority arrives, you have the qualifications to ask me to do anything."
Xu Nan nodded. "I want to transform Fireflow into the foundation base form."
Fireflow fell silent for a while. "Given Fireflow's current situation, after it changed into the foundation base form, it's almost impossible for it to regain the warship form. At the very least, it would need vast amounts of titanium alloys and other legendary-grade industry spells to recover."
"Confirm the change to the foundation base form?"
Xu Nan went out to inform everyone before choosing to confirm it.
At the next second, the outer surface of the flying warship began to dissolve like jelly.
The mysterious titanium alloys became a half-liquid state and were flowing according to some internal rules. Fireflow monitored the space underground while asking Xu Nan for his instructions.
Xu Nan got Miss San to come over. Under the guidance of Shi Fanglin's professional judgment, the titanium alloys gradually transformed into large and tall walls, as well as the floor and dome!
The control room, the power furnace, the resting zone, the weapon storage, the library...all the structures in the flying warship automatically shifted to various corners of the new foundation base.
All these changes took less than 20 minutes.
The imps stared at all of this. They suddenly felt a sense of losing their jobs.
Even Soupy was alarmed.
Right now, in the underground city. The sky and dome had a layer of faint silver metallic liquid flowing, and tall and strong walls were erected in the surroundings.
What was even more wondrous was that Fireflow was intelligent enough to avoid the underground river. It chose the underground river's side to be the settling ground for the flying warship.
The perimeter of the foundation base form was more than 4 square kilometers within the surrounding walls. Although it wasn't a standard 'square', the length of the edges was approximately close to 2,000 meters. In addition, there were many ready-made constructs in its interior. It was a pity that the majority of the constructs were in a crippled state.
Even so, it was much better compared to the gnoll camp.
"This is like a transformer!" Shi Fanglin was excited after seeing this scene.
He, who originally came for Lu Junyi, was now mesmerized by the flying warship. Xu Nan also magnanimously passed him the manual.
Anyway, Xu Nan was the one with the administrator authority of the flying warship; the others only had the ordinary access of crew members.
With a new base, there was no need to worry about the descent of monsters that might happen tomorrow.
Those small monsters directed here by the gods of Puluo World had no way to climb over these titanium-alloy perimeter walls!
"Xu Nan, Xu Nan. Is this our underground city?!"
Qin Lele stretched out her head from a room on the second floor as she cheered excitedly.
Xu Nan nodded with a smile.
"To celebrate the completion of the underground city we built with our own two hands and effort… I decided to activate the only system available for usage! Waiter, turn on the air-conditioning!"
…
Xu Nan solemnly sent a command to Fireflow.
Although Fireflow didn't understand the word 'waiter', it still followed the command and turned on the central air-conditioning system.
Very swiftly, the airflow in the base started to move. The originally stuffy underground space became much airier.
Everyone was quite happy. After all, they had never seen such a rare plaything before. Fireflow who was present everywhere patiently answered all their questions.
Xu Nan then went to look for Gu Xiaomeng.
"Don't chase me away. I won't leave."
Gu Xiaomeng opened her eyes wide. "My...my...she hasn't returned my panties yet!"
Xu Nan muttered, "Why is the goddess of love and girls looking for me exactly?"
Gu Xiaomeng shook her head to indicate that she had no idea.
"I'm only following her orders. But the goddess wouldn't have bad intentions toward you. After all, she only wants to spread love… She might feel that you have the potential to spread love."
Xu Nan couldn't help but ridicule himself silently. "Potential to spread love?"
"I don't eat a lot." Gu Xiaomeng pitifully looked at Xu Nan. "Can you just let me stay here for now? No matter what, I'm a priestess and I also know a little medical knowledge. Maybe, my understanding of it is even deeper than Doctor Lu! I might be of use somewhat. I've asked those imps, they said you guaranteed their lodgings and meals. I just want the same conditions as them!"
Alright then.
Since a young woman like her had said all these, it wasn't too good for Xu Nan to coldly chase her away, right?
He waved his hand. "Alright then, the same conditions as the imps. You will be under observation for a month."
Gu Xiaomeng patted her chest and heaved a sigh of relief.
Xu Nan glanced at her back view. Upon seeing that she was now running to choose a room happily, he suddenly felt ashamed in his heart.
In truth, he felt that having an additional nanny in the base wasn't a bad thing.
...
There were many ready-made constructs in the interior of the warship, but Xu Nan commanded Fireflow to temporarily seal many of them up.
After all, given a mortal's intelligence, it was easy for unexpected accidents to happen if they tried to probe the secrets of high-ended facilities designed by the arcanist empire. This was especially so considering there was someone restless like Qin Lele. Xu Nan had to remind Fireflow three times.
He chose a small castle-type construct to be the city lord's great hall. All the buildings constructed by the imps before were now leveled to the flat ground. There was no choice for this; they were simply too ugly looking.
Currently, Xu Nan's status was different from the past. He couldn't afford to lose face.
After he made arrangements for some of the outstanding tasks, a bottle with a message in it once again shot out from the Kaiser's Gate!
Xu Nan didn't find it strange as he calmly held the bottle.
During these few days, he would converse with that highness Kaiser, and both parties became exceptionally close pen-pals. Although their motives were most probably not pure, at the very least, they were both quite agreeable to each other.
From Kaiser, Xu Nan understood much information he had no way to obtain from his bloodline.
Xu Nan had learned that Kaiser was a prince and possessed a powerful, wealthy territory!
Kaiser also knew that Xu Nan was one of the best spellcasters on Earth with the most prospects. He had already begun building a majestic underground city!
The two of them formed an alliance agreement of mutual exchange. Kaiser waited impatiently for Xu Nan to send more people over, while Xu Nan calmly asked Kaiser for more maps of different areas in the Puluo World.
"I wonder what topic this pen-pal of mine is going to share with me today?"
Xu Nan happily opened the bottle.
Today, Kaiser's words looked extremely messy!
It was like he wrote them in a hurry.
"Respected City Lord Xu, a piece of urgent news just circulated from the divine kingdom. The first day will be pushed forward!"
The first line of the message caused Xu Nan's heart to tremble.
At this moment, everyone on earth heard a gentle voice announcing beside their ears.
"The first day is here."
