Sylvia turned her head to look at the Feast Palace behind her, then at the backpack she was carrying behind her, and asked Leo in disbelief, "How did we get out?"

"That's how it should have come out. Leo nodded, and said with some confusion: "It seems too easy, it is a little different from what we expected, has the guard of the French Palace been so lax all along?"

"Of course not. Sylvia shook her head, but for a moment she didn't know how to prove her words, because from what had just happened, the guards of the palace were incredibly lax.

Starting from the Seventh Research Institute underground, all the way to the outside of the Feast Palace, where they are now, although the two of them encountered some small obstacles, they were very smooth on the whole, and in the last section of the road from the treasure house, passing through the underground station of the royal guards to the Feast Palace, and then out of the Feast Palace, it was as easy as walking in their own back garden.

Originally, Leo and Sylvia both thought that they would definitely have to fight when they finally got out of the treasure house, and they were even ready to fight their way out, but they didn't encounter any danger in the end.

The two teams of knight squires guarding outside the treasure house, the heavily armored soldiers guarding the passage, the knights and knight squires walking back and forth in the royal guard station, so many people seemed to be all blind, ignoring the package that Sylvia was carrying behind him, and had no doubt about the identity of the two scholars, and none of them stepped forward to ask.

After that, none of the palace guards, palace attendants, chamberlains, maids, etc. in the Feast Palace expressed any doubts about the identities of the two, even though Sylvia was carrying an extremely eye-catching backpack behind her.

Leo walked to a stand on the front lawn of the Feast Palace, and glanced at the undulating palace buildings in front of him, and found that there were a large number of guards stationed in these buildings and in the corridors, and judging from the positions and patrol routes arranged by these guards, they seemed to pay more attention to the movement outside the palace, so Leo said: " Since the construction of the Royal Palace, it has never been invaded, so it can be seen that the guards of the Royal Palace of France are very tight, but their tightness seems to be only for the intruders from the outside, and it seems that we are not guarded against this kind of infiltration from the inside. ”

Sylvia thought about it, nodded approvingly, and said, "That's fine, it saves us a lot of trouble." As she spoke, she looked towards the southeast side of the palace, then pointed to several towering stone pillars in the palace buildings in the distance, and said, "Airships usually dock in the square there. ”

Leo followed Sylvia's gaze as well, and although the layers of palace buildings obscured the square, Leo's extraordinary eyesight still helped him see through the gaps between the buildings.

As Sylvia had said, there was indeed an airship docked in that plaza, but it didn't seem to be the one that picked up Colin, but a different one, smaller in size, and there were a number of mechanic-like men around the airship doing some kind of testing.

Leo told him what he had seen, and Sylvia immediately understood what was going on, and said, "It should be the Royal Academy doing airship tests there, and it looks like we're going to pilot a new airship with unknown performance." ”

With that, Sylvia led the way with her backpack on her back, followed by Leo, and the two walked from a spiraling staircase not far away to a cloister on the next floor, and then through a downward cloister path, through two arches, to the small garden of the palace, and then to the location of the square.

As Sylvia described, the palace is very tightly guarded, in addition to the royal guards patrolling the fixed line, there are at least ten or more heavily armored guards in some key places, and above some palace buildings, there are also guard points and other facilities, you can easily see the surrounding situation, and there are alarm measures set up in the position of the guard points, as long as there is a slight abnormal movement, the whole palace will enter a state of martial law.

It's just that for Sylvia, these palace guards and guards are of no use, she knows very well the role and importance of each building in the palace, and knows where to go will be intercepted and questioned, so she always finds some route that can bypass the interception point, and keeps pushing towards the square.

Along the way, although the two of them encountered a lot of palace guards and royal guards patrolling back and forth, they did not encounter a single incident of being intercepted and asked about their identity, maybe some people were a little puzzled by the package Sylvia was carrying, but they were just puzzled, and I don't know if this was because their attitude was too natural, or if the royal scholar's clothes on their clothes played a role.

In the process of traveling, Leo also saw in many places in the palace hidden in a large number of decorative patterns, the use of unknown Turing arrays, these Turing circles can be said to be on the tower wizard Turing array, not only Leo learned the Turing root combination method in it, there are more Turing circle layout techniques that Leo has not learned, if it is not the place and timing is not appropriate, Leo may stay here to learn the core content of the tower wizard.

Now that I think about it, it is not so difficult to understand that the Count Phelps I met before is a wizard with the inheritance of the wizards of the tower, and it is not difficult to find that the relationship between the wizards of the tower and the royal family of France was very good in a certain period of time, so good that some of the wizards of the tower were directly left here in the royal family of the tower.

It's just that now these Turing circles that were used for defense have all failed with the statue of the Stone Throne moving here, and it is impossible for these Turing Circles to have any effect until the power of the Stone Throne disappears.

About ten minutes later, the two of them walked to the edge of the square without any danger, and at this time there were seven or eight guards standing around the airship in the square, they were not on guard of the surrounding situation, but curiously watching the airship, without thinking that there would be any attack behind them.

Next to the airship, there were seven or eight men dressed as mechanics adjusting the wings of the airship, and the steam jet accelerator on the back seemed to be testing the new airship.

This airship is different from the airship that Leo saw before, first of all, the airbag of the airship and the fuselage of the airship are not separate but integrated, and the overall shape of the airbag of the airship looks like a kind of sea barracuda, slender and sharp, and finally the thruster of the stomach of the airship is no longer a propeller airflow thruster, but a steam jet thruster.

All the technologies used on this airship are not new, but some that have existed in the past.

When Leo took over the mechanical engineering factory and metal smelter in Port Set, he bought a large number of books related to machinery in order to study the development of steam machinery in the world, and these books were also mixed with some kinds of books, such as the fantasy of steam machinery.

At the moment, all the seemingly innovative aspects of this airship come from some steam-mechanical fantasies, such as the shape of a sea barracuda, which is a book called "Romance in the Air", and the steam-jet thruster is also from a book called "The King of Maritime Merchants", but in that book this propulsion device is used for sea ships.

Obviously, Fran's airship mechanics got inspiration from those seemingly absurd books and built the airship in front of them, which should still be in the experimental stage, and it seems that Emperor Fran doesn't attach much importance to it, otherwise he wouldn't have assigned a few people to be in charge of the security of this airship, and he wouldn't have let the people in the palace approach this airship at will.

Right now, for example, Leo and Sylvia easily walked past the unsuspecting palace guards, and they didn't stop them.

After the two of them walked up to the group of mechanics who were doing the final checks, Sylvia asked directly and tentatively, "Are all the test preparations ready?"

These mechanics who were doing the final overhaul were stunned when they heard Sylvia's inquiry, obviously they didn't know Sylvia, but their eyes showed respectful looks after seeing Sylvia and Leo's scholars' robes, and replied without concealment: "The fuel has been prepared and ignited, and a new round of testing can be carried out at any time." Are you ready to take part in this test?"

"Yes. Both of us took part in this test. Sylvia nodded and said.

Although the mechanics did not understand why two royal scholars were interested in the testing of this experimental airship, they did not dare to ask more, because they knew very well that in the palace, the less they knew, the safer they were, and if they accidentally knew any forbidden knowledge, they might not even know how to die.

So they didn't ask Leo and Sylvia about these things, quickly completed the overhaul of the airship, and then beckoned to the royal guards who were in charge of the security of the airship, and greeted Leo and Sylvia on the airship, and then the royal guards also got on the airship, but they were puzzled by Leo and Sylvia, the two people who suddenly joined in, because there were no two people in the order they received.

It's just that they don't want to ask more, because the performance of the mechanics just now shows that these two people should also be participants, otherwise the mechanics would have driven them away.

After everyone got on the airship, the pilot who was responsible for controlling the airship walked to the rudder of the airship, quickly pulled a few control senses next to him, and there was a sound in the airship, followed by the whole beginning to vibrate a few times, and then slowly floated up and flew into the air.

Although it was not the first time that the airship had been tested, the mechanics and guards who participated were still a little nervous, and even if it was flying smoothly now, their nervousness did not subside.

"Now test the propulsion capability. After the airship rose to a certain height, the pilot stopped the ascent, and then pulled the lever of the steam jet thruster, and a powerful momentum was transmitted in an instant, and the spacecraft rushed forward at a very fast speed.

Although the mechanic and the guards were on guard, they were still staggered by the sudden momentum, and even the driver fell to the ground because of the unexpected momentum, and his hand naturally broke away from the helm.

The out-of-control rudder rotated rapidly, causing the airship to lose its direction, and when it was about to happen, Leo grabbed the rudder on the side, and then quickly turned twice, putting the airship back on track, and at this time the airship had flown out of the palace range, and Leo and Sylvia could feel the extraordinary strength of their bodies returning to normal.

"Thank you, thank you! If something else happened to you," the pilot got up from the ground, thanked Leo who was in control of the helm, and said, "Let me drive! We're out of range now, and we'll be punished if we don't go back immediately." ”

"It doesn't matter, the airship didn't fly out of my test range. Leo easily controlled the helm, adjusted the direction of the airship to the direction of the Black Forest, and said to the pilot.

Leo's words weren't very big, but they were still accessible to everyone in this semi-sealed environment.

Not only was the driver puzzled by Leo's words, but even the others had puzzled expressions on their faces.

However, their confusion did not last long before one of the mechanics realized something and shouted, "Who are you, what do you want to do?"

At this time, everyone realized that Leo and Sylvia's identities were probably not what they thought they were, and the mechanics sat on the ground in fright, while the royal guards all touched their weapons, apparently trying to capture Leo and Sylvia and atone for their crimes.

But before they could make any moves, a powerful pressure appeared on them out of thin air, and then they felt as if they were being pressed by a boulder, and they were out of breath, and their eyes were black and fainted.

"It's a good feeling to have power! It was so uncomfortable before. Sylvia couldn't help but sigh as she watched the effect of releasing her power.

Leo didn't feel so emotional, he felt that the thrust of the airship was weakening, so he said to Sylvia, "You come to pilot the airship, I'll go add some fuel." ”

After saying that, he handed over the control of the airship to Sylvia, and he found the location of the stove room through the spirit network, picked up the shovel, and sent the fuel next to him to the stove one by one.

The airship, which had been slowing down, began to maintain a high speed of flight after a large amount of fuel was added, and soon flew out of Winter Rin City.

Almost as soon as they flew out of Winter Rin, all the alarm bells in the palace were sounded, and it was clear that they had discovered that the treasure house had been robbed.
