Hearing the call, two maidservants waiting outside the door knocked on the door, one of them was Youcao, who had married with Lin Ruo, and the other was Qingqu, the eldest maid in King Rong's mansion.

"Lord, princess, what do you command?"

Lin Ruo set his eyes on Murong Chong, and seeing that he didn't mean to open his mouth at all, he ordered: "Go to the kitchen and get a pot of boiling water, and then ask someone to boil some white porridge and send it with some light side dishes." ”

"Yes."

The two maids retreated, but Qingqu obviously deliberately slowed down a few steps, and secretly looked at Lin Ruo a few more times.

Lin Ruo didn't care, and after they withdrew, he called again: "Ah Shu! ”

A figure, like a ghost, suddenly appeared, standing in front of the two of them. It's just that after his cold gaze swept over Murong Chong, he looked at Lin Ruo without any hostility.

"Someone is approaching, warn in advance."

Leng Shu nodded, and seeing that Lin Ruo didn't give any other orders, he turned into a figure and disappeared quickly, without a trace.

"The second killer in the world, it's really powerful." Murong Chong looked at Leng Shu's disappearing figure, praised his skills, and then looked at Lin Ruo, "Dare to entrust your safety to such a person, Jun ...... You're extraordinary, too. ”

Murong Chong has always called Lin Ruo "county lord", but it is a little inappropriate at the moment, but he can't call the word "princess", and he paused for a long time before replacing it with the word "you".

"There is no suspicion in employing people, and there is no need to suspect people." Lin Ruo was very leisurely and responded lightly, "It's good for the prince to call me Ah Ruo, you must get used to this, otherwise it will be easy to goof." ”

Murong Chong's face showed a slight embarrassment, and then he nodded and said, "Okay, Ah Ruo." ”

"I have extinguished the warmth incense, the prince can rest assured. This wedding wine should have added something, and I drank many glasses in the banquet hall, and the prince didn't want to drink more, right? ”

Murong Chong nodded: "That's true." ”

There was a sound of footsteps outside the door, Murong Chong heard it before Lin Ruo, and wanted to remind her, but seeing her knowing look, he listened to the knock on the door and said "Come in".

Youcao pushed the door in, put the teapot on the coffee table covered with red brocade, looked at Lin Ruo, and saw her smiling lightly and signaling her to retreat, so she didn't stay long, exited the new house, and closed the door.

Lin Ruo took out the box that had never left his body, and explained: "I have a different sense of smell than ordinary people since I was a child, if someone comes, Ah Shu will use special spices to warn, and the prince doesn't have to worry." ”

Murong Chong suddenly said: "I see, that's the ......"

"Youcao has always been by my side, so Ah Shu is relieved to let her in."

Murong Chong nodded, and looked at the box that Lin Ruo moved out, a delicate rosewood box, or rather, a piece of extremely poorly made rosewood, with no delicate carvings, only vertical and horizontal lines, which made people sigh that the craftsman was so violent!

Lin Ruo's fingertips fiddled on the wooden box, and Murong Chong realized that he had guessed wrong again—this wooden box was not poorly made, but ingeniously designed! The vertical and horizontal lines are very regular, and the pieces of wood that are cut by the lines can be moved down with the tilt of the fingertips, and then the lines on the whole wooden box are rearranged to become ten neat pieces, four small squares, one large square, five rectangles, and there is a rectangular space in the middle.

Lin Ruo did not stop, skillfully fiddling with the ten pieces of wood, until he removed the largest square from the gap on one side, there was a "click" sound in his ears, Lin Ruo's face showed a smug smile, both hands held the two small bolts that popped up in the middle, opened the wooden box one left and one right, and took out things one by one: a letter, a box, and a scroll.

Murong Chong's gaze still stayed on this seemingly ordinary but incomparably delicate wooden box, and he exclaimed: "The structure of this wooden box is really unique. ”

The corners of Lin Ruo's mouth hooked, and he smiled proudly: "That's natural, I found dozens of craftsmen, and in the end, only one person took over the drawings, and it took more than half a year to complete it." Except for me, there are only a handful of people who can unlock this thousand-machine lock, and even if they can get the drawings, they may not be able to disassemble it smoothly. ”

"Thousand machine locks?" Murong Chong was very surprised, but his perennial self-control made him not show a very exaggerated expression: "You mean, this is designed by you?" ”

Lin Ruo raised his eyebrows: "Hasn't the prince ever heard that the design drawings of the young lady of the Lin family in Bian'an City are hard to find?" ”

Murong Chong's eyes were deep, and after pondering for a moment, he praised sincerely: "I thought you were just good at drawing jewelry hairpins, but I didn't expect that you were also proficient in the art of organs, and you really hid it deeply." ”

"I am not humble when it comes to tinkering with these strange things; But the female red needlework of the ordinary women's club, I can't even compare to Su Boyu. Lin Ruo laughed at himself, and when his eyes stayed on the box, he couldn't help but smile smugly, "This box is called 'Tianji Lock', the first layer is the 'Fourteen Tangrams', as long as you pour down the sections in order, you can unlock it; After each unlock, 'Huarong Dao' will be rearranged, but 'Fourteen Tangram' will not. ”

"Oh? It sounds like the first layer is easier to crack, but how do I feel that there is another mystery in it? ”

Lin Ruo couldn't help but praise: "The prince is really a smart person. This 'fourteen puzzles', the graphics that can be spelled out are ever-changing, although the position of the puzzle has not changed, but the graphics to unlock the puzzle are not the same, the prince looks here. ”

Lin Ruo's fingertips pointed to the lower left corner of the box, and there were several small raised dots.

Looking at Murong Chong's confused eyes, Lin Ruo explained with a smile: "In the lower left corner of this wooden box, there are four small boxes, each box has six small dots, each two small boxes represent a number, and the four small boxes represent two numbers, and this number corresponds to the final shape of the puzzles, that is, the order of pouring down the fourteen puzzles. ”

Murong Chong twisted his eyebrows and thought for a moment: "In other words, each of these fourteen pieces of puzzles actually represents a key, and it must be touched in the exact order before this secret box can be opened?" ”

"The prince is wise, he found the key so quickly!"

"Then why don't you use words to express it?"

"It's easy to remember the order of words, but it's hard to remember the order of the puzzles!"

Murong Chong nodded: "Indeed." ”

"If it were written up, the lock would have been made dead; But if it is represented graphically, the secret lock is alive, and it is convenient to remember the secret language of unlocking with graphics. ”

"However, even if there are only two numbers, there are nearly 100 kinds of figures!"

Lin Ruo nodded: "So, others can't disassemble it!" However, generally only I will use this more complex Tianji lock, Xiao Qi will use a simpler one, and the upper layer only uses 'tangrams', and the graphics are only preset to ten kinds. It's easier, you can use the 'tangram', but there are only three chances to unlock such a thousand locks, if the three times are wrong, or if you want to forcibly open the box with brute force, the box will automatically burn. If you are interested, I can give you the drawings. If this 'Thousand Machine Lock' is used to convey the secrets of military aircraft, it is the most suitable. ”

Murong Chong nodded, pondering slightly: "If it can work, it will naturally be good." However, I am afraid that this 'thousand machine locks' are too complex and difficult to popularize. ”

"Don't worry about this prince, although this jigsaw technique sounds complicated, it is not difficult to learn, as long as you can master the rules, you can learn it quickly."

Murong Chong couldn't hide the joy in his heart: "That's great!" However, if you teach me this method, you are not afraid that leaking this method will have an impact on the Lin family? ”

Lin Ruoyin smiled: "Lord Wang, you also underestimate me, right?" What you should be worried about is that I can crack the message you want to spread at any time, instead of worrying that the Lin family will be threatened because of this. ”
