"It's ...... How?" Thunder opened his mouth in disbelief. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

There were dozens of small holes in the walls, and in each hole was placed a stone that glowed pure white, and not only that, but even the upper edge of the ceiling was placed with a circle of this strange glowing stone, and in the soft light, every detail of the hall could be seen.

It was the first time that Ash had seen an explorer with such an expression, and he couldn't help but feel a wave of joy in his heart, "Don't you know? ”

"And what about these, are they magic stones?"

Thunder carefully took out a luminous stone and held it in his hand, and after leaving the small hole, its light did not diminish in the slightest.

"I don't know," Tilly shook her head, "these stones may have been glowing here for hundreds of years—if the ruins were that old. They had been hidden behind stone slabs before, so they had never been discovered, and only witches could unlock this special mechanism. ”

"Didn't you make them light up?"

"No, they emit light on their own," Tilly grabbed a magic stone and held it up to her eyes, the white light reflecting her beautiful face, "If this is a device that requires mana to sustain it, then it can't be taken down so easily, just as a candle flame can't easily leave a candle." At the moment, the holes in the walls are nothing special other than providing for the placement of glowing stones. ”

"If it is true as you said, it can emit light on its own and can continue to shine for hundreds of years, then its value is simply immeasurable," Thunder said in amazement, "You must know that the snow crystal produced in the Eternal Winter Kingdom can sell hundreds of golden dragons with a fist-sized piece, and the brightness is less than half of it." ”

When the sailors heard such an astonishing price, their eyes changed when they looked at the stones.

"As we said before, you can take half of it," Tilly said noncommittally, or her focus was not here at all. With plenty of light, she could explore the hall more closely. Ash couldn't bear to watch her tear the seaweed piece by piece, so she simply picked up her big sword and swept away all the attached plants on the wall like mowing grass, and soon, the second magic stone hidden in the wall was also discovered.

Tilly does the same thing, infusing it with magic. With the crisp sound of metal crashing, everyone was surprised to see a large stone slab slanted down above Tilly's head, with several taut copper ropes pulled on either side, and a hewn staircase on the inside. Eventually, one end of the slab slowly fell to the ground, and the other end led to the top of the ceiling, and Ash looked up to see a horizontal metal door blocking the end of the passage.

"Tilly," Seeing the Five Princesses walking up the stone stairs alone without hesitation, Ash couldn't help but speak, "Let me come first." ”

"It's okay, it's not like that...... Where the treasure is hidden," she climbed to the top of the stone staircase and grasped a raised magic stone beside the door, and the metal door quickly opened.

Seeing Tilly burrow through the door and disappear into the ceiling, Ash had no choice but to follow closely and hold the greatsword in his hand.

Across the roof, Ash's eyes widened to see that above the ceiling was a room much smaller than the hall, with glowing stones embedded in the walls—and to her surprise, there was almost no sign of water immersion.

Wooden tables, chairs, bookshelves, cabinets...... Everything is intact, covered in a thick layer of dust, and even broken cobwebs can be seen. On the shelves were neatly arranged rows of books, all stained gray with dust. On the table, in addition to the spread out books, there were cups, kettles, and pen holders, and the quill pen was left with a lone rod, and the ink had long since dried up. Compared to the hall full of algae and shells below, it's like two worlds.

Thunder climbed up the third, looked around and gasped, "This is ......"

"Abandoned abode," Tilly picked up the books spread out on the table, gently dusted them off, and flipped through the pages, "Someone has lived here for a long time. ”

"What's written on it?"

"I don't understand," she said, shaking her head, spreading out the book to the two of them, "It's all words you've never seen before." ”

"The same seems to be true on the shelves," Ash wiped the dust off the spine with his fingers, and the words were like strange wavy lines, completely unreadable.

"We can take it back and study it slowly," Tilly laughed, "and by agreement, the books and the magic stones are mine." ”

"Of course," Thunder stroked his beard, "but when you find something, hopefully share this old story with me." ”

"No problem. ”

......

The three of them searched carefully in the room on the second floor, and quickly felt the general situation.

Instead of finding a new magic stone, they found a strangely shaped object at the other end of the room—what at first glance looked like a thick metal tube, one end sunk into the stone wall, the other knotted out, and finally only the thickness of a wrist and a glass lens embedded in the end.

"What is this?" Ash tapped on the barrel, and a series of crisp echoes came from inside—apparently hollow in the middle.

"It's kind of like a nautical goggle, maybe people who live here use it to observe the outside world," Thunder looked at the lens for a moment, "and it was dark...... I can't see anything, it should be broken. ”

"Not necessarily," Tilly pointed to the wall behind the metal pipe, "Look here." ”

Ash looked in the direction of her finger and saw a copper plate with a handle embedded in the wall, and a small hole under the handle, which appeared to be a place for the key to be inserted. The Fifth Princesses walked over and tried to pull the handle, but the copper plate didn't move, "It's locked." ”

"I'll do it," Ash grabbed the handle and pulled hard, and the entire copper plate suddenly fell off the wall.

"Ha, I think you guessed right," Thunder applauded, "another magic stone mechanism." ”

A large magic stone was stuck in the groove behind the copper plate, and unlike the previous two, it looked much larger and purple in color.

"Do you want to activate it?" Ash asked.

"Hmm," Tilly nodded without hesitation, gripped the stone with both hands, but this time there was no movement.

"What's going on?"

"It'...... It's too big," beads of sweat already appeared on her forehead, "I feel like it's draining the mana, and it seems like the mechanism behind it is huge. ”

"Forget it," Ash frowned. She knew that once her magic ran out, the witch would likely fall into a coma, and it was obviously not a good choice to spend all her magic in such a dangerous place.

"No, it's almost ready, I can feel it. Before Tilly could finish speaking, a loud noise came from within the wall, like a continuous thunderclap, and then the whole room shook.

"It's ...... Thunder clings to the metal pipe to prevent herself from falling, and Ash grabs Tilly and takes her into his arms. The dust was pouring down, and the three of them couldn't help coughing.

The tremors lasted for nearly a quarter of an hour before calming down.

Moriel poked her head out of the stairs, "What just happened?"

"A new trap," Ash pouted, "how are you down there?"

"Everyone was terrified, and there were a few roofs that fell, but luckily I covered them with magical minions. The little girl walked up to her side, "Master Tilly, what are you looking at?"

Surprisingly, Tilly didn't answer her, her eyes kept to the end of the metal tube, and it took a long time for her to let out a long breath, "It's incredible......"

Ash curiously leaned his eyes to it, and was speechless in shock by the sight before him.

At the other end of the "lookout glass" emerges a vast expanse of land, the edge of which is like a cliff, and there is no bottom in sight. In the center of the cliff stood a huge stone arch, deep and dark, like a huge mouth that chooses people to eat. (To be continued.) )
