Due to the large space, Reina Takasaka and Guhan were able to stay far away from each other. Therefore, nothing interesting happened between the two of them.
Guhan's main focus was on studying the Flying Droplet.
After several hours of research, Guhan gradually discovered many more amazing technologies about the flying droplet. Some of them seemed like black technology to modern humans.
The black technology of the Droplet Flying Car could be summed up in four words, and that was "Do as you please". Gu Han could almost do anything with his mind … This was not just controlling the Droplet Flying Car to fly, in the hundreds of square meters of folded space of the Droplet Flying Car, Gu Han could use his mind to materialize anything.
For example, if Guhan wanted to sleep, a bed would immediately appear next to him. If Guhan wanted to wash his hands, a sink would immediately appear. If he wanted a private bathroom, a fully equipped bathroom would immediately appear.
Such an experience made Guhan feel like he had become a god.
However, Guhan soon discovered that these things that appeared were the same.
If he wanted a chair, a chair would indeed appear.
However, when he wanted to ask for a red chair, the chair that appeared just now was still the same one.
Another example was if Guhan wanted a bed. No matter how detailed Guhan described it, he wanted a small, simple single bed. In reality, a luxurious double bed made of pure wood would always appear.
It was the same for the bathroom. If Guhan wanted a squatting toilet, it would always appear as a sitting toilet.
Moreover, not everything Guhan wanted would appear. For example, if Guhan wanted a sword, there would be no response from the Flying Droplet.
If Guhan wanted an animal like a cat or a dog, nothing would appear.
Combining these phenomena, Guhan quickly figured out that these things that appeared out of nowhere were actually created in advance and hidden in the folded space. Once Guhan received the command from his mind, these things hidden in other spaces would immediately appear beside Guhan.
To put it simply, the Flying Droplet was like a sword wielder with its own dimensional pocket. Once Guhan gave the command, the Flying Droplet would take out what Guhan wanted from its dimensional pocket.
Therefore, when faced with some very detailed requests from Guhan or something that the Flying Droplet's dimensional pocket did not have, the Flying Droplet could no longer meet Guhan's needs.
After fully understanding this point, Guhan fell into deep thought.
The dimensional pocket was something that could only be used by the sword wielder, and it required the sword essence of the sword wielder to be able to freely enter and take it out.
If the Flying Droplet really used the technology of the dimensional pocket, then it must mean that in the Lemurian civilization 60 million years ago, humans could also freely use the sword essence … As for whether there was a Swordmaiden at that time, only God knew.
Moreover, Guhan also vaguely discovered that the ability of the Flying Droplet was not as simple as it appeared to be.
When Guhan's mind controlled the Flying Droplet, he could vaguely feel that the Flying Droplet had some deeper functions.
But this function showed a state of complete resistance to Guhan's mind. No matter how Guhan conveyed his thoughts, the sealed things did not respond, and Guhan could only give up on this exploration.
…
When it was late at night, Guhan could finally see a brightly lit city in front of him. Guhan had returned to Yuzhang City, and it had only been eight hours since Guhan set off from Yanjing City.
Such a short time not only surprised Guhan, but even Reina Kosaka was completely stunned.
It must be known that it took Guhan seven days to travel from Yuzhang City to Yanjing City in the armored levitating train, but now it only took him eight hours to return to Yuzhang City.
Of course, there were many other factors involved. For example, the armored levitating train used at least four days to repair the broken highway between Yuzhang City and Yanjing City.
And Guhan's journey was smooth. Not even a dragon-class Yuan Kou could catch up with Guhan's speed. He returned to Yuzhang City almost without stopping.
But that wasn't the main reason. The main reason was the Droplet Flying Car's superior ability to ignore terrain.
When faced with complicated terrain, the levitating car could only travel at a speed of less than 100 kilometers per hour, sometimes even less than 10 kilometers per hour.
But the Droplet Flying Car could ignore the same terrain. It flew over the terrain without even slowing down. That was the main reason why the Droplet Flying Car could return to Yuzhang City in only eight hours.
"Let's go to the city!" Guhan said to Reina Kosaka.
Reina Kosaka nodded and followed Guhan to Yuzhang City.
But halfway there, Rena Takasaka realized that something was amiss. Rena Takasaka had lived in Yuzhang City for less than a month, so she had a basic understanding of the city's geography.
Gu Han, who was leading the way, did not walk towards the city gate of Yuzhang City. Instead, he headed towards a location in the northwest corner of the city wall. Even if she was beaten to death, she would not believe that there was a city gate there.
"Where are we going?" Reina Kosaka asked. "This isn't the way to the city."
"I can't go through the gate."
Guhan replied faintly. "If it's possible, I hope that no one in Yuzhang City knows that I'm back. Do you understand what I mean?"
"Are you going to do something shameful this time?" Only then did Reina Kosaka realize that Guhan's purpose for coming back was not simple.
"It's indeed something shameful!" Guhan nodded and admitted readily. "Are you going to report me?"
"I'm not human. I don't care if you humans live or die," Reina Kosaka muttered softly and said no more.
It was only when Reina Kosaka and Guhan arrived at their destination that Reina Kosaka realized that she was wrong. There was indeed a gate at the northwest corner of the city wall.
The gate was a hidden door, and no one was guarding it. Looking from outside the city wall, there was no sign of the gate's existence at all.
However, as soon as Guhan got close to the city wall, he tapped on a small depression on the wall, and the originally seamless wall slowly opened up. Through the opening, Guhan and Reina Kosaka easily entered Yuzhang City.
"How do you know there's a hidden gate here?" Reina Kosaka immediately regretted asking this question. She immediately realized what was going on.
A hidden gate like this must have been designed by the Kenjutsu to arrange escape routes or to launch a surprise attack on Yuan Kou. Guhan was once the Kenkaku Cabinet Master in Yuzhang City, so he must know all kinds of secrets in Yuzhang City.
Sure enough, Guhan answered, "This is an emergency exit. There are more than 20 such exits in Yuzhang City."
After walking out of the hidden door, Reina Kosaka returned to Yuzhang City after two months.
Reina Kosaka hesitated when she saw the familiar yet strange city. She did not know how she should face the city.
"Oh right, I have a question for you!
Reina Kosaka shouldn't be your real name, right?
If I remember correctly, Reina Kosaka is the name of the swordswoman in Yuzhang City. You're just impersonating her. What's your real name? "Guhan suddenly asked.
"Fleeting Rena …" Reina Takasaka, who was immersed in her own thoughts, blurted out her real name. However, the name was not surprising at all. She had merely changed her surname to Fleeting Time.
Guhan had already guessed that Reina Kosaka was Fleeting Time's daughter from his conversation with Fleeting Muki and Fleeting Masa. However, he did not expect her real name to be Reina. It was the same name as the person she had impersonated.
"My name is not Fleeting Reina! It's Reina Kosaka!"
Fleeting Reina yelled at Guhan. She seemed to hate the name from the bottom of her heart.
"Whatever. I'll call you Reina then!" said Guhan, and continued walking towards the Core Area.
Guhan had many questions about Fleeting Reina.
The most important question was whether Fleeting Time Rena was a human or not.
Guhan had witnessed Fleeting Reina's ability to control the air with his own eyes. She did not have any swordmaidens in her hands at that time, which meant that Fleeting Reina did not borrow the power of the swordmaidens. She had used her own power to control the air.
Where did Fleeting Time Rena's power come from?
Did she awaken a superpower from a novel? She was able to control the power of the wind with her human body?
Or was she the same as Misaka Mikoto, a human from another world? In other words, Yuan Kou?
Guhan had been keeping a close eye on Fleeting Reina when she passed through the Dimensional Barrier of Yuzhang City. If the Dimensional Barrier was able to obstruct her, Guhan would immediately give up on the idea of letting Fleeting Reina enter Yuzhang City. He would instead send her to the Heaven and Earth Furnace to wait for him.
However, nothing out of the ordinary happened when Fleeting Reina passed through the Dimensional Barrier. Guhan had no choice but to keep his worries to himself.
