Because those halls just now are essentially the mysteries of this floating city...... It can be regarded as a kind of embodiment of the space inside the lock.

Such a powerful lock made Ain have some palpitations. Generally speaking, the Lost Lock, as the largest and most critical part of the entire Floating City project, often directly determines the arcane level of a Floating City.

However, because of the strength and integrity of this lock, Ain can't help but be full of confidence in the harvest in this floating city - maintaining the lock, especially maintaining this very high level of lock, requires a huge amount of magical energy, and these magic energy can basically only be provided by the Nethether Nuclear, a nuclear reactor-level energy source. Including the magic street lamps that are still bright in the city, as well as the magic towers around it, all show that this floating city is still full of vitality.

However, mages are also under pressure to face a vibrant floating city that could be hugely rewarding - because all the means of protection have plenty of magical energy to use, mages will inevitably have to be aware of these various and still very hidden methods as they explore the floating city. And even if you notice it, you may not be able to deal with it, and you may have to find a way to bypass it in the end.

Counting the number of candle heads in his arms, Ain found that he could only unleash five summoning monsters. But looking at the tower in the distance, which was still glowing with magical energy, a candle head disappeared from the mage's hand, turning into a celestial rat and scurrying towards the mage's front.

Or the Celestial Rat to explore the way, Ain still chose this safer method. Although the Celestial Rat does not have such a big advantage in this environment, its small size and relatively flexible characteristics make it capable of general exploration work.

Before he had taken a few steps, the spiritual connection between the Celestial Rat and Ain in the distance was suddenly disconnected - there was only one possibility, that is, the Celestial Rat summoned by Ain had disappeared into the main plane.

Aine immediately stopped, looked around for a moment, and immediately flashed into a nearby house.

"Whoa, whoa, whoa." The sound of three breaking sounds reached Iron's ears as she pushed the door in, but at this time, Al was already prepared and activated the malachite enchanted with the spell of protective arrows in his arms.

Not surprisingly, the arcane aura of the spell of protective arrows that lit up around Ain blocked the attacks of the three arrows. Although these arrows were obviously tainted with deadly poison, they did not choose the expensive magic arrows, and were naturally easily blocked by Ain with this two-ring spell.

Looking around the house, it was clear to Ain why he didn't need to use magic arrows to stop it - it was a very ordinary warehouse, full of signs of decay. Some of the carbonized bits were scattered on the ground, apparently the iron hook that had been hooked to the jerky had decayed. As for some faint traces that can be seen on the other corners, it is estimated that most of them were originally the place where the barrels were placed.

It may be that the buildings of the Floating City will be protected by magic energy and close to eternity, but these dead things are not within the protection of magic energy, from the beginning of the Third Age to the present, it has been thousands of years, this kind of iron and mundane things have naturally turned to ashes - even some ordinary magic weapons are not able to stop the power of this passage of time, on the surface it may seem that it can still be formed, but once you touch it with your hand to destroy the original decaying balance, then it will instantly turn into dust.

However, these things, which had long since lost their value, were not worth Ain's attention at all, so the mage walked to the window and tried the locked window a little, but sure enough, it didn't move at all.

Closing the door of the house, Ain applied a sealing spell to the door from the inside - because this magic lock used in the floating city is quite difficult to crack, and Ain really doesn't want to save trouble today to lock it, and then waste most of the day tomorrow on the calculation and cracking of this magic lock. And if someone with a certain amount of authority comes over, they can easily use the management core in the floating city to unlock the magic lock on this door.

In addition to sealing the door, Ain also set up several magic locks on the door to trigger. Even if Ain himself only has the strength of the three rings, the structure of these magic locks was only studied in the later stages of Ain's previous life game, and the mage is confident that there is no way to directly crack these magic locks except for the direct erasure of them by violence.

After doing all this, Ain silently took out food and water from his space bag, replenished his strength, and then fell asleep.

The sudden disappearance of the Celestial Rat, and then the absence of any creatures coming along, can only prove one thing, it may just be that the Celestial Rat accidentally touched a certain mechanism, and in general, the entire Floating City is still safe.

However, Ain's spells enchanted on his robes and the spell slots he remembered were now in a state of complete depletion, and he urgently needed a break to recover, so it was better to use the house on the side of the road as a cover to restore his strength.

When Aine woke up from his deep sleep and rubbed his eyes, he noticed that it had become gloomy outside.

Although Ain suddenly felt deeply worried when he saw the sky outside, at this time, he still chose to memorize some spells first-even if he didn't memorize spells, he could just use the magic pool to cast spells, and then use the magic energy pool to convert these unused spell slots into magic energy the next time he fell asleep and rested. However, the habit that Ain had developed in the game for so long in his previous life still made him memorize a few commonly used spells first.

Half an hour passed, and Aine got up from the ground, shook off his legs, which were a little numb from sitting cross-legged, moved a little, and then ate to comfort his already hungry stomach before unlocking the multiple magic effects on the door and carefully opening the door a crack.

The street was still so silent, and there was little change from before Ain fell asleep, and the only thing that reflected the vision of the sky was the color of the mystery that represented the sky.

The white part slowly fades to the west, and the blue-black layer is covering from the east.

"I didn't expect that this lock could be used to simulate day and night...... "Al Ain couldn't help but exclaim. In his previous life, he had also dug up several floating cities in the game, most of which fell in the magic net disaster at the end of the Third Age, so the degree of damage was very high, and even if there was a complete floating city, it was not as big as this floating city.

However, while sighing, Ain's own intuition suddenly caught some not-so-normal feelings.
