When the sunlight advanced to a certain angle, a light from the lake happened to shine on a pillar in the middle of the ruins pavilion where Sylvia and Leo were. Leo immediately felt an energy wave emitted from the pillar, which merged with the energy waves at the top of the three surrounding mountains, as if some kind of restriction was stimulated.

"It's already turned on, let's go in!" Sylvia suddenly said to Leo, and then saw her walking quickly towards the lake, stepping into the reflection of the setting sun on the lake, and disappearing in an instant.

Seeing this scene, Leo seemed to understand and followed, stepping on it. Just as his feet fell on the lake, what he felt was not the insignificant water surface, but the solid land. At the same time, the scene in front of him was no longer the lake view, but a lake-like island that was not too big.

"This is the secret library I discovered back then." Sylvia stood beside Leo, looking around with a little nostalgia, and sighed: "So many years have passed, but this place has not changed. Perhaps millions of years have passed, and there may not be any changes here."

"Well, you're right!" Leo looked around and agreed: "As long as this sub-space fragment does not collapse, everything here can be preserved forever."

"Subspace fragments?" Sylvia looked at Leo in confusion.

Leo did not explain much, but looked around seriously and launched a spiritual network to investigate the surrounding situation.

Although this island looks like an island in the middle of a lake, it seems to be in the previous mountaintop lake, but in fact it is all illusions. Now the location of Sylvia and Leo is no longer the old capital of Panier, and it is no longer even the world of Viron. Instead, it is in a subspace plane attached to the world of Viron. This can be proved by the fact that Leo's spiritual network is no longer affected.

The island is not big, with a flat surface and no buildings. Standing in Leo's position, you can see the entire island at a glance.

Except for the line near the water, the entire island is covered with polished and flat rocks. Except for a few places slightly arched, the other places are very flat. If you stand in the air and look down, the island is more like a large platform in the water.

There are five identical buildings on the island, all of which are palace-shaped buildings, built in the direction of the four corners. The interior of the four corners is solid, which should be converted from four small hills on the island, and the central building is a normal building, but it is just the appearance of the building, and the interior looks very strange, because there is no decoration or facilities inside the palace, and there is only a square stone house, with a relief door that looks like a carved on the surroundings and top of the house.

After searching with the Spiritual Network, Leo said in a deep voice: "This place was not built by the Paniers. The style of these buildings is completely different from that of the Paniers."

"I think so too. The architectural style here is somewhat like the desert style of Saville," Sylvia nodded, then walked to the nearest solid building, pointed to the densely carved patterns on it, and said, "But the relief words on it are not Saville's words, nor are they any of Viron's words. I have printed one before and asked some linguists, who all said that these words do not belong to any of the world's writing systems."

"Of course it doesn't belong." Leo also looked at the words on the relief and said, "They are not words at all, but fragmented patterns of wire diagrams."

"Conductor diagram?" Sylvia was also a little surprised.

Leo did not explain, but quickly selected more than a dozen different patterns from the wall, and then spliced ​​them according to certain rules to form a complete wire diagram. He then said to Sylvia, who had not yet fully understood, "This is a concentrator wire diagram fragment of an energy weapon. Its function is to divert the introduced energy by five levels so that the concentrator can control the output intensity of the energy beam."

Although Sylvia still didn't understand what Leo was saying, she already understood what Leo meant, that is, the picture he had just put together was part of a certain device, and the other pictures should be similar, so this was not the language she thought.

"Is this built by the Starry Sky Civilization?" Sylvia guessed again.

Leo has told Sylvia some things about cosmic civilization in the past, but because it is difficult to explain the meaning of the universe in any language in the Viron world, he used the starry sky to describe cosmic civilization as a civilization above the sky.

Hearing Sylvia's guess, Leo shook his head and said, "No, I suspect this is built by the tower wizard."

After saying that, he pointed to a decorative object that looked inconspicuous on the edge of the roof of the building. This decorative object looked like the head of a monster, and like several symbols intertwined. Although it was strange, because there were other decorative objects around it, it was easy for people to ignore it.

"What is that?" Sylvia said in confusion.

"That is the badge pattern of the ninth tallest tower." Leo explained. If it were the past, Leo might not be able to distinguish the origin of this decoration. However, since he planned to rebuild the tower, many lonely wizards from the wizard gathering joined in. They had more or less books and notes left over from the tower in the past, which made him understand the internal structure of the tower and recognized the hidden badge of the ninth tallest tower at a glance.

"The ninth tower?" Sylvia thought for a moment and said, "I remember you mentioned that the wilderness wizard is the wizard of the ninth tower."

"Yes." Leo nodded.

"Is this a wilderness wizard built?" Sylvia asked again.

"It should not be calculated by time." Leo shook his head and said, "However, it should be unrelated to the Ninth Tower. The Ninth Tower was transferred to the wasteland after the tower was disbanded. This is why the wild wizard finally chose to go deep into the wasteland. Moreover, many of the wild wizards' witchcraft have something to do with the wasteland."

"Maybe the inheritance of the ninth tallest tower is preserved here." Sylvia smiled, and then said regretfully: "It's a pity that the key to opening the secret library is no longer there, otherwise..."

Leo interrupted Sylvia and said, "That Star Torch Eye may not be a key, and even if there is no key, it may not be impossible to open the secret library."

Sylvia also smiled, then walked towards the building in the middle, and Leo followed.

The two of them soon arrived in the building, stood in the empty hall, and looked at the square sealed house in front of them.

No wonder Sylvia immediately said that the Eye of Star Torch is the key to the secret library after seeing the Eye of Star Torch, because there is a groove on the relief doors on the wall. The size of the groove is exactly the same as the Eye of Star Torch, and the groove has been polished by extremely special methods. Although its smoothness cannot be compared with the Eye of Star Torch, it is not polished by any mechanical technology in the world of Viron. Leo even felt that even witchcraft would be difficult to create such a smooth surface.

The entire sealed room can provide too little information to Leo. There are no more carvings on the surface except for the relief door, and there is no hidden thing on the relief door.

Leo tried to penetrate into the sealed room with a spiritual net to see if this was useful. As a result, the information his spiritual net gave him was that there was nothing in front of him. In other words, in the perception of the spiritual net, this room that could be seen and touched did not exist.

Afterwards, Leo tried to use various forces to stimulate the hidden restrictions in the sealed room, but he still got nothing. Neither spiritual energy, divine power, nor witchcraft or abyss power could have any impact on the room.

"Stand far away." After all the attempts were fruitless, Leo thought of using the last method, so he ordered Sylvia and began to use the lightning gun.

After hearing the order, Sylvia immediately felt a spear formed by lightning condensed in Leo's hand, and the spear contained a very terrifying destructive power.

So she immediately walked out of the building hall, hid behind the wall outside, and carefully peeked into the situation inside.

Although the lightning gun quickly condensed in his hands, Leo felt that it might not be enough, so he continued to stack the spiritual energy, and the shape of the lightning gun began to change. It was originally the size of a short spear, but now it had stretched and bigger, becoming like a flagpole. The lightning on the surface became thicker and thicker, and it exploded. Even the lightning spreading was like thunder whips whips on the surrounding stone walls, pulling cracks on the stone walls. Seeing the building becoming riddled with holes and cracks under the thunder whip.

Sylvia outside also felt that the distance was still too close, and retreated far away, and stopped until she retreated to the edge of the island. At this moment, rasers had smashed the buildings and swept through the other four other buildings transformed with hills, tearing them apart together with the hills.

As the lightning light in front of me was about to lose control, but in the blink of an eye, all the lightning light disappeared. The thunder storm formed by the lightning light collapsed and contracted into the lightning gun in Leo's hand as if it was captured by some invisible force. At this moment, the lightning gun shrank again, and was smaller than the beginning, only the size of a piccolo. This lightning gun was no longer interesting from the inside out, but instead appeared in a dark purple color like a nebula.

Leo seemed to feel that his superposition of the lightning gun had reached its limit, so he projected towards the four-sided room in front of him.

Almost the moment he made the projection action, the deep purple lightning gun had already hit the Sifang Room. There was no amazing scene afterwards. The entire Sifang Room collapsed and dissipated with the lightning gun, and finally turned into a pile of dust.

At this time, Sylvia might have felt that the movement inside had ended and walked over again. After bypassing the ruins of the building, when she saw Leo standing alone in the center of the original hall, she couldn't help but be stunned and asked, "Where is the secret warehouse?"

Leo smiled awkwardly and said, "I seem to have used too much force. The house has been completely destroyed, and the things in the house may not be preserved."

"Ah?" Sylvia didn't expect such a result. She was stunned for a moment, looking at the ruins in front of her, and was puzzled and didn't know what to say for a moment.

Just as Leo was about to check again to see if something was left, the entire island or space suddenly shook, and then an invisible force grabbed Leo and Sylvia and threw them out of the island.

When the two of them landed on their feet, they found that they reappeared in the ruins of the lakeside pavilion where they had set out before. The lake water in front of them flowed rapidly in a vortex shape, and the water surface gradually retreated, just like a hole was opened in the middle of the bottom of the lake to drain the lake water.

The lake water faded quickly, and it was exposed in a moment. At this time, Leo and Sylvia did not focus on the bottom of the lake that was about to be completely exposed, but looked behind her. The shaman apprentices of the ancient spirit tour sect who were practicing on the altar of the old capital came over under the leadership of Rustav.

Leo and Sylvia looked at each other. Although they didn't say anything, their eyes had already exchanged views. Obviously, both of them thought that Rustav and others were not attracted by the movements of the lake just now, because these people appeared too early. If it was movements on the lake, it would be transmitted to the altar, and these people discussed and then came over. It would definitely take a long time, but now it appeared here in such a short time, which only means that these people had already hidden in this garden before.

"It seems that you have found the biggest secret hidden in the Sky City." After walking not far in front of Leo and Sylvia, Rustav couldn't wait to ask: "What is it? What is that secret?"

Neither Leo nor Sylvia paid attention to Rustav's inquiry, but glanced at the people around her. Although these people looked normal, Leo and Sylvia could feel that these people had a fanatical temperament similar to those of the crazy believers, and Rustav's current reaction was also very wrong.

Rustav, who once worked at Sylvia's hands, should be very clear about Sylvia's strength, and if he is not so obsessed with things in the outside world, he should be able to recognize Leo. But now he is so reckless and rude facing a powerful witch and a tower wizard, which is obviously inconsistent with his past personality.
