“This is... how did you do it?”The thunder could not bear to open his mouth in disrepair.

There were dozens of small holes in the walls, and a pure white light was placed in each hole, and more than that, even the edge of the ceiling was placed a circle of this strange luminous stone, and under the soft light, every detail of the hall was at a glance.

The ash was the first time he had seen the explorer show such an expression, and his heart could not help but raise a pleasure, "Don't you know?"When a witch injects power into the magic stone, it can stimulate additional abilities.”

“What about that?Is it a magic stone?”

The thunder carefully removed a luminous stone holding it in his hand, and after leaving the small hole, its light did not weaken at all.

"I don't know," said Tily, shaking her head, "these stones may have been shining here for hundreds of years—if the remains were that long history.They had been hidden behind the slates, so they had not been found, and only witches could open this special organ.”

“Didn’t you let them light up?”

"No, they can shine on their own," said Tilly, holding up a magic stone, and the white light shone her beautiful face, "if it is a device that needs magic to maintain, it cannot be taken down so easily, just as a candle cannot easily leave a candle."At present, the holes in the walls are nothing special except the luminous stone.”

“If, as you say, it can shine on its own and shine for hundreds of years, the value is simply immeasurable,” said Thunder, “and know that the snow crystals produced in the Kingdom of Yongwinter can sell hundreds of golden dragons, and the brightness of less than half of it.”

As soon as the sailors heard such an astonishing price, the eyes of the stones suddenly changed.

“As we said before, you can take half of it,” Tiley said, or her focus wasn’t there at all.With plenty of light, she could explore the hall more closely.The ash could not bear to see her hand tearing the seaweed, simply picked up the sword, like a lawn mowing the wall of the attachment to the plant as much as possible, and soon, the second piece of magic stone hidden in the wall was also found.

Tilly, in the same way, injects magic into it.With the sound of crisp metal impact, people were surprised to see that a huge slate above Tilly's head was tilted and lowered, and several taut copper ropes were pulled on both sides, and the inside was a well-cut staircase.Finally, the slate fell slowly to the ground at one end, and the other end led to the top of the smallpox, and the ash looked up, only to see a horizontal metal door blocking the end of the passage.

"Tili," said the Grey, seeing that the Fifth Queen's woman had not hesitated to walk up the stone ladder, and the ashes could not help opening her mouth.

“It doesn’t matter, it’s not... a place to hide treasure,” she climbed to the top of the stone ladder, holding a raised magic stone by the door, and the metal door quickly opened.

Seeing Tily burrowing into the door and disappearing into the ceiling, the ashes had nothing else to do, so he had to keep up and hold the giant sword in his hand.

Through the top plate, the ash could not help but stare, and above the smallpox was a room much smaller than the hall, and the walls were also filled with luminous stones—and what surprised her even more was that there were few traces of water-soaked here.

Wooden tables, chairs, bookshelves, cabinets... all the furnishings are intact, covered with thick dust, and even broken cobwebs can be seen.There was a neat row of books on the shelves, all stained with dust.In addition to the books spread out on the table, there were cups, kettles and pen racks, and the quills were left with only one pole, and the ink had dried up.It is like two worlds compared to the halls full of algae and shells below.

The third Thunder climbed up, looked around and took a cold breath, “Here is...”

“Abandoned dwellings,” said Tily, holding up the books spread out on the table, gently patting them off the dust, turning the page, “someone has lived here for a long time.”

“What was written up there?”

"I don't understand," she said, shaking her head, and showing the book to both of them. "It's all words you've never seen before."

“It seems the same on the shelf,” Ash wiped the dust off the spine with his fingers, and the words were like strange wavy lines, completely uninteltriate.

"We can take it back and study it slowly," laughed Tilly. "As promised, books and magic stones are mine."

"Of course," said the Thunder, touching the beard, "but when you find something, you may want to share this old story with me."

“No problem.”

...

The three men searched the second room for a careful look around and soon touched the general situation.

They did not find a new magic stone, but found a strange shape on the other side of the room - it looked like a thick metal tube at first glance, one end did not enter the stone wall, the other end was narrowed, and finally only the wrist was thick, the end of the glass lens.

“What is this?”The ash knocked on the tube, and a series of crisp echoes came from the inside—obviously hollow in the middle of the tube.

"It's a bit like a nautical lookout, maybe the people who live here often use it to observe the outside world," the Thunder put his eyes to the lens for a while, "black ... can see nothing, it should be broken."

"Not necessarily," said Tily, pointing to the wall behind the metal tube, "look here."

The ash looked in the direction of her finger, and saw that there was a copper plate with a handle on the wall, and there was a small hole under the handle, which seemed to be the place for the key to insert.The five princesses went over and tried to pull the handle, and the copper plate was not moving. "It was locked."

"Come on," Ash held the handle, pulling hard, and the whole copper plate suddenly fell off the wall.

"Ha, you seem to have guessed it," said the Thunder, "it's another magic stone organ."

A huge magic stone card in the groove behind the copper plate, unlike the first two, it looks much larger in size and is also biased towards purple.

“Do you want to activate it?”Ash asked.

"Well," said Tily, noding without hesitation, holding the stone in her hands, but this time she was motionless for a long time.

“What’s going on?”

“It’s ... too big,” she said, sweating beads already on her forehead, “and I feel it’s a steady stream of magic, as if the body behind it is so large.”

“Not to mention,” Ash frowned.She knew that once the magic was exhausted, the witch was likely to fall into a straight coma, and that spending all the magic in such a dangerous place was obviously not a good choice.

"No, it's going to be good, I can feel it."There was no sound, and a loud noise came from inside the wall, like a continuous thunder, and then the whole room shook.

“Is this an earthquake?”Thunder held the metal tube to prevent himself from falling, and the ash caught Tily the first time and held her in her arms.The dust came down and the three men couldn’t help but cough.

This shock lasted for nearly a quarter of an hour before gradually regaining its calm.

Molly leaned out of the stairs and said, “What happened?”

“A new organ,” Ashes flanked, “is it all right below?”

"Everyone was terrified, and there were a few more roofs that fell, and I covered them with my magic servant."The little girl came up to her, “Mr. Tilly, what are you looking at?”

Unexpectedly, Tily did not answer her, her eyes have been attached to the end of the metal tube, after a long time to spit out gas, "it is incredible..."

The ashes curiously put their eyes over, and then could not speak in shock at the sight.

At the other end of the "lookout mirror", a vast land appeared, and the edge of the land was like a cliff, and the bottom could not be seen at a glance.In the middle of the cliff stands a huge stone arch, deep and dark inside the door, like a big mouth to choose people.(Unfinished.
