The door that hides the secrets of Sky City is about to be opened, and at this point, neither Lin An nor Salin will retreat.

"Come here."

Lin An said, asking the center to open a passage from the direction of Salin's location to the central room, and a passage appeared on the wall of the room where Salin was in the light mirror.

As previous inspections had confirmed that there was no danger in the area, after half an hour, the walls of the central chamber gradually became transparent, revealing a square passage about a foot by a kilometer, from which Salin stepped out.

While waiting for Salin, Lin An had already asked the center, and the center marked the path from the second division to the purple-level sacrificial area, and Lin An wrote it down.

As soon as Saleen stepped out of the passage, the walls were slowly obscured by an illusion-like fluctuation, and on the surface, it looked as if it had turned back into the wall.

Then, as Lin An asked for the path to the purple-level sacrificial area, another passage was exposed at the same position on the opposite wall, and the air flowing out of it had a faint dry musty smell.

Salin's dark golden Source Crystal Staff tapped at him, and a reaction spirit armor that resisted the invasion of the void body was put on his body, and then an invisible magic ball floated above his and Lin An's heads.

Under the illumination of the looming light of the magic ball, the figures of Lin An and Salin slowly disappeared in it, and then a few feet outside the irradiated range of the invisible magic ball, the high-level phantoms of the two appeared again, and they looked at each other.

"Since you may be the main attacker, then I have to be a supporter." Salin calmly said that he had no pressure to eat soft rice.

Lin An was speechless for a moment, but he was secretly surprised by the progress of Sarin's strength in his heart.

"Reaction Spirit Armor", "Invisible Magic Ball" and "Advanced Phantom" are undoubtedly very suitable for the current situation, but they are all third-level spells, among which the "Reaction Spirit Armor" has not even been learned by Lin An, of course, the main reason why she has not learned it is that her actual spiritual power protection effect is better than it, and there is no need to learn it again.

But she is a special case, normally speaking, a mage can choose the right spell in the corresponding environment, and undoubtedly needs more spell accumulation to make the foundation.

Salin has only been on the stage for two years. He has mastered so many third-level spells in a short period of time. At least in terms of the speed of spell comprehension, it is quite unique, considering that he has been undercover and hunted down for a long time after he has been promoted, then the speed at which he masters new spells is not much different even compared to Lin An, who had the help of space acceleration back then, after the death of Kronos, Lin An now deduces the speed of mastering a third-level spell, I am afraid it is not as fast as Salin.

"If Heaven closes a door, will it leave another window for him?"

Lin An suddenly thought that in fact, in addition to his background, Salin's own talent was actually not inferior to Andrei, if he could focus on magic like Andre without being distracted. Maybe even get ahead of Andre and them.

But Lin An thought about it, if Salin didn't have ambition and greed. Then he can't come to this point, it can be seen that the wonder of fate is difficult for mortals to understand.

These many thoughts were just a flash, Lin Aneng did not delay the preparations to be made, and realized his spiritual power to gently hold up his body, and entered the passage three inches above the ground.

The passage is very short, like a corridor of about twenty or thirty zhang. Lin An and the two walked out of another exit, and there was a sandwich road in front of them.

The stone of light embedded in the ceiling at a height of three feet is very dim, like a fluorescent lamp turned off and emitting a faint glimmer in the darkness.

There are two doors on each side of the passage, both of which have been opened, and Lin An doesn't need to enter to know what is going on inside, because this is the passage she used to enter when she first entered the ruins, and on the white wall covered with gems on the side, you can also find the pits left by Lin An after prying off the gems.

"What a luxury!"

Because Lin An dug up the gems and blocked the magic pathway, and most of the light stones were dug up by Lin An. So in the dimness, he couldn't see the light refracted by those gems, but Lin An knew that when the light was on, how beautiful the gemstone patterns on both sides were, enough to dazzle any woman.

After leaving the passageway, the passage in the wall slowly disappeared behind them, and Salin glanced back and said, "Let's go." ”

The white corridor is about six or seven zhang wide and three zhang high, and if it weren't for the rooms on both sides, it would feel like a small hall.

Lin An and Salin walked through one corridor after another, Salin didn't know what magic he used, and the two ghosts of the high-level illusion in front of them, with the dry musty air and the white wall inlaid with colorful gems, accompanied the two of them all the way, and the light stone on the ceiling automatically lit up wherever they went.

"I'm starting to truly believe that this is a temple." Lin An said to Salin.

Tons of large quantities of precious stones outlined dense and beautiful patterns on the obsidian walls, and after seeing the same scene too much, I unconsciously gave birth to a solemn and solemn feeling, as if I could feel the traces of the faith of the demigod era countless years ago engraved in this ruin, and the two slightly musty air seemed to be wafting with the breath of piety at that time.

As they walked, a white bridge appeared in front of the two, quiet and cheerful with a hint of oppression, Lin An and Salin were surprised to see the flowing floating clouds on both sides of the floating bridge, submerging the back half of the white bridge like a mountain cloud.

The entire white bridge jumped into the sea of clouds like a rainbow, connecting the purple-level sacrificial area with the second division, if Lin An didn't know that the ruins were buried and underground, he would have thought that this ruins were actually floating in the sea of clouds.

"Given my last experience of walking on a pontoon, this kind of pontoon doesn't feel good to me." Lin An muttered.

Salin knew that she remembered the pontoon bridge in his ruins, and remembered that the experience of reuniting with him after participating in the auction was unforgettable, and he smiled:

"Although this is the second time to enter a similar ruin, each time it can open a different horizon, and the most brilliant crystallization left by prehistoric civilization is truly dazzling!"

Lin An didn't speak.

Her previous words were actually to suppress the excitement and excitement, especially when she thought that she would be able to pocket this ruin, presumably even the old monsters who had been in the world for a long time might not be able to be without waves.

Glancing at Salin, Lin An immediately floated onto the bridge deck, and Salin immediately followed.

But there was only a few steps before and after, and Salin watched as the white clouds that filled the bridge surface surged, engulfing Lin An's figure.

And if there is a third party behind him, he will also find that Saleen has suffered the same treatment after walking on the bridge, and he has been swept away by the white clouds.

Lin An sensed the anomaly as soon as Salin disappeared from perception. The Guardian Ring, which radiated a faint golden glow, immediately appeared around her body. The surrounding white clouds, which were so thick that they were almost substantial, were driven out of the sky, but Salin, who was obviously four or five paces away just now, was gone.

"It's not an illusion, it should be a spatial effect, and Saleen and I shouldn't be in the same place." Lin An recalled the strangeness he felt a moment before, and determined the slight spatial fluctuation.

But she was not worried about her safety, although the outside of the Ring of Guardian was full of thick clouds, Lin An did not feel the danger, Lin An trusted her instincts, thought for a moment, and continued to walk in the direction before.

Time after that. It seemed like a few days, and it seemed like just a few moments.

Lin An felt like he had been walking in the clouds and fog with no way to see the road for days. Hunger, exhaustion, and mental exhaustion appeared on her one after another, but every time Lin An was confused for a short time, he realized that it was an illusion with his strong mental power.

When Lin An walked out of the clouds and mist to the other end of the bridge, the color of the Guardian Ring only faded slightly, and the seemingly endless trek in the clouds and mist had actually passed less than half an hour.

Lin An had already understood that the bridge was a test for her apprentice, and she waited under the bridge for a while, and sure enough, the tall and thin figure of Salin holding a staff quickly appeared from the clouds. Seeing Lin An's golden eyes, he was faintly confused and vigilant at first, and then he came to his senses, obviously understanding what was going on.

"What do you see in there?"

Lin An noticed Saleen's vigilance, suspecting that the trials he had experienced might be different from hers, otherwise he was just walking in the clouds, and would not let Saleen doubt her authenticity at the first sight of her.

"I walked for a long time, and then I saw you, but I soon realized that it was a hallucination."

"I just kept walking, and after two or three days of walking, I came out." Lin An pondered, "It seems that the illusions created by the clouds and mist will set up different illusions according to each person's differences, I originally thought that this was just a simple test of will and mental power. ”

"It may also have something to do with the difference in our mental power, the trial is stricter on those with low mental power," Salin said, "I feel like I've been walking in there for at least half a month." ”

Lin An thought for a moment and nodded.

This illusion is obviously only a test for low-level apprentices, and most of the illusions are controlled to the lower ones, so Lin An's perception can easily find the flaws in it, and Salin's spiritual power can also be regarded as an advantage, and he has come out smoothly after encountering some tests.

But this didn't mean that the ruins couldn't create a more powerful illusion, but it deliberately controlled the intensity of the illusion, just like the kind of illusion for time perception, Lin An couldn't break it, and he felt like he had been trekking in it for several days, and he didn't understand it until he left the illusion.

"It's just that low-level trials are so difficult, so wouldn't those apprentices whose spiritual strength has just broken through the critical limit have to stay in the illusion realm for a year and a half?" Lin An smacked his tongue.

"They're ready to go into the trial, not like we have no warning."

"That's right, and when it comes to mental strength and tenacity, fanatics often have a huge advantage." Lin An thought for a while and said.

In fact, the two mages who claim to be smart people have misunderstood the point, in fact, if you think about it carefully, you can understand that the people who walked on this bridge are all sacrificial apprentices who have made breakthroughs in spiritual power, and the spiritual power of the apprentices who have just broken through the critical limit is almost the same, basically at the same level, and the cloud illusion actually tests the piety and will of the newly promoted to the gods, and will create all kinds of illusions to test their faith.

It's just that Lin An and the others have no faith, and their spiritual power is far beyond the critical limit, so they passed the trial in a monotonous and a hundred times simpler way.
