"It seems that we really have a tacit understanding." Hei Lu'er showed a faint smile again, "Does this mean we have a tacit understanding?"
"That's what you said." A'Piao nodded. She walked to the big dog and sat down. She gently rubbed the big dog's head and said slowly, "When we were on the road just now, I was thinking, This little thing was encountered near here. Since it is responsible for guarding, it basically means that the real entrance to the secret room is nearby."
"Yes, I think so too." Hei Lu'er held a fire folder in one hand and observed carefully nearby, "The two circles we made before were probably used to confuse us." He stretched. Waist, "This little thing is the key, maybe it is used to guide us."
"Then you are overthinking. Are they so kind? The original idea was to scare us with this, but unfortunately it didn't work. However, this little guy is a bit stupid. If you change it to another one, it might not be so smooth. , it is very likely to alert the snake."
"You are right to say that, but the scare was successful." Hei Luer turned around and spread his hands, "You scared me."
"If you expose your shortcomings like this, you should say less in the future!" Ah Piao raised her eyebrows slightly, "Any special discoveries?"
"There's nothing special, the feeling is the same." Hei Lu'er looked up and down on the wall, and then at the marks on the ground. "From the situation on the ground, we can see that the entrance to the secret room can be defined here." He Pointing to the wall beside him, he walked forward seventy or eighty steps, then turned to Ah Piao's side, passed by Ah Piao, then walked back around, making a circle with his own steps. "If we want to find the entrance, we have to find it within this range."
"Why?"
"Intuition!" Hei Lu'er raised his chin towards the big dog, "The range it guards should be about the same, right?"
"It's possible." Ah Piao nodded slightly, stood up from the ground, stretched his legs and feet, and walked twice along the path drawn by Hei Lu'er. As he walked, he looked around, looked at the walls, and then looked at On the ground, "Your Majesty is right, it should be within this range, but I am different from you, I have reason."
"What kind of evidence? Tell me."
"The colors of the walls look almost the same. I mean the color of the wall tiles..." Ah Piao reached out to touch the wall, but she took it back halfway and took out a small bag from her small bag. After putting on the deputy gauntlet carefully, he reached out to touch it again, "Although it looks similar, there is actually a slight difference. The color of the wall tiles in this range designated by the adults is lighter than that in other places. .”
"Shallower?"
"That's right. Only if the color is lighter, will it be difficult to detect differences. If it is darker, it will be easier to detect. This is where the people who built the secret room put their heart and soul. Only those who are good at observation can discover it. "
She raised her eyebrows at Hei Lu'er, and while talking, she knocked on the wall. Suddenly she heard a muffled sound, and she frowned slightly.
"What's wrong?"
"There's a problem." Ah Piao glanced at Hei Lu'er, then knocked on the wall tile again. When she heard a muffled sound, she confirmed that she hadn't heard wrong. She knocked a few more bricks next to it, and when she heard the crisp sound, she turned her head and looked at Hei Luer, "Sir, come and see."
Hei Lu'er heard A Piao's words, walked up to her, took the gauntlet she handed over, put it on and tapped on the wall.
He first knocked on the piece that A Piao pointed out to him, and then continued to knock down, left, and right along this piece, and found seven wall tiles with different sounds. He made each wall tile a different sound. After marking it, I knocked on the opposite wall. Similarly, I found the wall tiles that made the sound in a symmetrical position.
"This should be the key to opening the secret room." Hei Lu'er spread his hands towards Ah Piao, "But, unfortunately, I'm not very good at this." He looked at Ah Piao, "I can only rely on you."
"No problem. I've played puzzles with His Highness many times before."
Ah Piao nodded. There were a total of sixteen wall tiles that made empty noises. However, it took a little trial and error to find out the rules of how they should be arranged and combined to open the secret room.
She knocked each wall tile several times. The sound of these sixteen wall tiles were all different, ranging in size and crispness. Judging from the sound alone, they were different. Without any rules, I don’t know what the key to solving this puzzle is.
"These wall tiles seem to be movable?" Hei Lu'er reached out to touch one of them, pressed it lightly, and found that it popped out a little. When he pressed it again, the wall tile retracted back to its original position. "If we push out all the wall tiles, can we open the secret room?"
"Try it!"
Ah Piao pressed each of the sixteen wall tiles one by one, and each one popped out, but it was of no use and there was no movement at all.
The two people looked at each other and couldn't help but sigh at the same time. They really didn't know what the purpose of this secret room was. It was really embarrassing to have such a complicated design.
While Ah Piao was thinking, she unconsciously pulled out a brick next to her. The moment she pulled it out, she heard a crunching sound.
"What was the sound just now?" Hei Lu'er looked at Ah Piao and then at the wall tile in her hand, "Did you dig it out?"
"Hmm!" Ah Piao raised an eyebrow at Hei Lu'er, "How about you try and dig them all out? How about you see what happens when you dig them out?"
"Okay!" Hei Lu'er nodded, "Let's treat the dead horse as a living horse doctor!"
The two people discussed it, summoned their confidants, and each of them pulled out the remaining fifteen bricks at the same time.
The moment the wall bricks were pulled out, they heard a crunching sound, and then they felt that their eyes suddenly opened up, and another secret passage completely different from the previous one appeared.
"This secret passage... seems to be the real entrance to the secret room. We found it by accident." Hei Lu'er touched his chin and looked at the big dog next to him, "We were able to discover this thanks to this It’s a big dog.” He looked at Ah Piao, “If His Highness knew about it, he would probably allow you to keep it.”
Ah Piao raised her eyebrows slightly and looked at the new secret passage in front of her, "Have you rested?" Seeing everyone nodding, "Let's go!"
This secret passage is much wider than the one just now. There are also lanterns hung on the walls on both sides of the secret passage, so they don't need to light any more candles.
Looking further on the ground, the traces of human walking and dragging are more obvious than before.
Hei Lu'er and A Piao looked at each other, which meant that they were close to the goal they were looking for, and their hearts started to pick up again.
