"This is...if I'm not mistaken, this thing should be obsidian, right?" Seeing Xue Ruitian nod, Shen Cha frowned slightly, "Obsidian in this shape is not very common, it should be polished by humans. It was made into this shape intentionally, but have you ever found anything with a similar shape just now?"
"Not yet. If there is, it won't be confusing, right?" Xue Ruitian shook his head gently and handed the obsidian to Shen Haolin, "However, it should be a very important thing hidden in such a secret place. , at least for my father."
"Well!" Shen Haolin put the obsidian in his hand and played with it, but his eyes kept falling on the door. After thinking for a long time, he said, "Do you think there is such a possibility that this thing is used for Where is the one who opened that door?"
"This?" Xue Ruitian looked at the obsidian and then at the door, "Key? Impossible!"
"Why is it impossible?" Shen Haolin raised his eyebrows, "As you just said, this thing is hidden in the most secret place in this tower, and this tower is hidden in the most difficult place to find in the bookcase. , if it’s not something that must be protected, there’s no need to hide it so tightly, right?”
"I understand this, but..." Xue Ruitian thought for a while, "How could this shape be a key? We have never seen such a key before, right?"
"Brother Tian It’s not a figment of imagination.”
"If it's a key, it must have something to carry it. I just studied the door panel carefully and found nothing unusual."
"Anyway, let's try it first, just in case, right? You also know that I'm lucky, I might just find it." Shen Cha took the piece of obsidian, walked to the door, and looked around After taking a look, he asked Hongye to help move a stone bench over, "I'll go up and have a look."
"Be careful!" Hong Ye looked at Shen Cha standing on the stone bench and quickly supported her below.
Shen Cha carefully groped the door up and down. As Xue Ruitian said, it was indeed a complete wooden board. There was no place for her to insert the so-called key. She stood on the stone bench and touched He held his chin and thought for a long time, then raised his fingers and tapped rhythmically on the door panel, trying to see if the so-called complete wooden board was really that complete.
But after knocking on the entire door panel, she found nothing unusual. She sighed softly and could only jump down from the stool.
"There's nothing, right?" Seeing Shen Cha nodding, Xue Ruitian spread his hands, "So, what's the use of this thing being so hidden? My father really doesn't understand why he has so many mysteries. It’s very brain-consuming!”
"It's also very temperamental!" Hongye rolled his eyes at Xue Ruitian, "Is there a possibility that it's because you are too impatient and don't have much patience for certain things, so the old Marquis Setting up so many traps? Of course, what the old Marquis wants to hide is indeed very important, but it won’t be impossible for people to find it, right?”
“For me?”
"That's right. You really don't have the talent in this area. Using this to temper your temper is indeed a bit...well, a waste." Hong Ye shrugged and focused on Shen Cha again. , "What are you doing?"
"Look at the differences in the surrounding walls." Shen Cha carefully observed the walls and book shelves near the door, and said while looking, "This is what mechanisms are like, everything that appears in this secret room, They all have their function. Since this key appears, there must be a matching card slot." She smiled faintly at Hongye, "So, no matter what the function of this obsidian is, does it open this door? All the key points are very important.”
"I understand." Hongye nodded, "Look for it slowly, don't be in a hurry."
"This is natural." Shen Cha said as she touched the wall again and again, and inadvertently touched a small seam. She was slightly startled, and leaned over to take a look. The small seam was completely invisible to the naked eye. You can only find it by touching it with your hands.
"What did you find?" Xue Ruitian also came over to take a look, "Isn't this just a white wall? There is nothing!"
Shen Cha raised her eyebrows at him, slightly raised the corners of her lips, and continued to touch slowly along the thin slit. Only then did she realize that this was not a straight line, but a rectangle. She smiled softly, turned around and walked away from the golden slit. Miaomiao found something like a small carving knife and pried it open bit by bit along the thin slits she felt with her fingers.
When this layer of disguise was completely peeled away, we saw the true face of Lushan in the notch. The shape and size were exactly the same as the obsidian.
"Brother Xiaotian, give me that stone." Shen Cha stretched out his hand towards Xue Ruitian, "Just say this works!"
When Shen Cha stuffed the obsidian into the slot tightly, the door that made everyone worried slowly opened. However, before they could be happy, someone flew out of the door. A few ropes were used to tie up Jin Miaomiao and Hongye who were guarding the door, making the two innocent people implicated dumbfounded.
"No, what's going on? Why are you tying me up? What have I done to tie me up?" Jin Miaomiao looked at the rope on her body, struggled twice, and found that the rope became tighter and tighter as she struggled, and she turned over helplessly. Rolling his eyes, "Xiaocha, please untie me quickly. This is simply an unforeseen disaster."
"Yeah!" Hongye, who was also tied up, nodded in agreement, "Even if we stand a little closer to the door, it won't be enough to tie us up, right?" She jumped twice with difficulty, turned around and looked at the smiling man. His Highness Prince Ning looked at them, "Your Highness, this can't be..."
"You're right, it's a mechanism. I designed it myself to prevent outsiders from sneaking in and opening that door."
"But Your Highness, the one who is opening the door now is not one of our own? How can one of our own be tied up too?"
"Because by default, our own people can escape. Those who can't escape will probably be tied up!" Shen Cha looked at His Highness Prince Ning who was smiling and nodding, "Is this what you mean, Uncle Wang?"
"Yes, that's what it means. Those who cannot avoid it are outsiders. However, this is indeed my king's negligence. I should have reminded you just now." His Highness Prince Ning raised his eyebrows, "Xiaocha, give them the rope." Pick it out!”
Shen Cha nodded, took the sword handed over by Xue Ruitian, and with two swishes, cut off the ropes on the two people.
"Uncle Wang, are there no other agencies here?"
"No, just go in with confidence!"
His Highness Prince Ning waved his hand and watched as several children cautiously walked into the room inside, with an imperceptible smirk flashing across his face.
