"There are hundreds of ways to test wisdom, but I want to see if you can remain calm in the face of a critical moment, and use your smart mind and keen insight to solve the difficulties in front of you."

Youmeng said, Pingting walked to a row of bookshelfs, and a flower-shaped candlestick that was almost human-high standing next to the shelf. "Branches and leaves" extending unevenly from the "trunk" to the surroundings, and red candles as thick as arms are lit on the "flowers" at the ends of the branches and leaves.

She turned a piece of red candles among them, and the row of bookshelfs seemed to be moved away from both sides, revealing a round carved stone wall secret door.

Nine dragons are carved on the door, with different shapes and lifelike life. Youmeng twists a circular knob surrounding the center of the Nine Dragons. The secret door opens, and a deep passage comes into everyone's eyes. Youmeng retreats into the secret grid, and the secret grid door automatically closes.

The men couldn't help but be stunned, and Min Qiuye said in surprise: "Princess?"

"This is actually a secret room." Youmeng's voice came from behind the secret door, "I have set up the mechanism outside the door. You can't open it inside, you must use the key."

"Key..." Li Feng thought secretly and his eyes began to scan around.

"The key is hidden in this secret room." There was a cat's eye where Youmeng stood, who could secretly observe everything in the room. The corner of her mouth was bent with charm, "You should pay attention to every clue in the room, they may be the clue I left to remind you."

The men looked around and found that there were many new items in the secret room, which were specially created by an emperor of the previous dynasty for him, called "Qijue Tower". This time Youmeng specially asked his father for the right to use the secret room and used various mechanisms in the room to test these families to test their minds and strategies.

"But I want to remind you that you have ten people, but there are only three keys." Youmeng said calmly, "That is to say, there are only three of you who can walk out of this door at most, and you only have half an hour."

While observing, Jing Rong walked to Li Feng: "Brother Mu, how about it?"

"I always think these two paintings are strange." Li Feng was looking up at the mural in front of him, "Why should we hang two identical Guanyin statues here?"

Under his guidance, Jing Rong began to glance back and forth at the two portraits with his eyes. He was shocked and said, "The direction of Guanyin's finger!"

As he said that, he quickly walked to a wall and tapped in different places. It turned out that there was a block that was hollow. He knocked again, and the bricks were automatically pushed outwards, which was a secret wall with an account book hidden inside. He took out the account book and took it to Li Feng: "Brother Mu, I found this."

Jing Rong flipped through it casually, only one account was recorded in the account book. Li Feng didn't have time to take a closer look, but he heard Min Qiuye exclaiming not far away: "You guys come and see this!"

Li Feng, Jing Rong, and some others all came up and found an exquisite wooden box embedded in the wall, sealed tightly, with four gears on the box, and numbers were engraved on the gears.

Min Qiuye was anxious to open it, but the box remained motionless.

"This is the mechanism password lock." Li Feng said calmly, "The box will only open if the gear is turned to the correct number."

"Password?" Qiuye frowned, "Who knows the password?"

"The clues left by the princess are interrelated." Li Feng's heart lit up and he immediately looked at Jing Rong, "Account Book."

Jing Rong immediately handed him the account book. Li Feng looked up again and saw a pocket gold abacus on the cabinet next to him. He quickly took it down, smoothed the abacus beads, and then carefully calculated the accounts. Everyone stared at him. The abacus beads were loudly buckled under his fingers. His fingering was smooth and focused. The result seemed to be in a flash.

"It's this number." He held the abacus in his hand and walked to the machine box. He compared the abacus arrangement and twisted the four gears on the box until the red pointer next to the gear pointed to it, showing the four numbers "eight, si, lu, 1".

Everyone heard a noticeable "click" sound, as if unlocking in secret. The closed cover slowly opened in response to the sound, and a round metal object was placed inside.
