Legendary star: Signed to the Palace at the beginning

Chapter 149 Luban Lock

Lubansuo is also known as Kongmingsuo and Baguasuo, as well as other names such as "Don't Sap", "Liuzi Lianfang", "Mo Naihe", and "Difficult People".

According to legend, it was invented by Lu Ban from the late Spring and Autumn period to the early Warring States period. During the Three Kingdoms period, Zhuge Liang made Lu Ban's invention into a toy-Kong Mingsuo.

It is a traditional civil building fixed connector in ancient China. The mortise and tenon structure, which was first created in ancient architecture, was once widely spread among the Chinese folk as an intellectual toy. It does not need nails and ropes, and is completely supported by its own structure, just like a piece of paper. Folding in half can stand up, showing a seemingly simple, but condensed extraordinary wisdom.

The concave and convex parts inside this three-dimensional splicing device (that is, the mortise and tenon structure) are very ingeniously engaged.

The original is a wooden structure, and the appearance looks like a seamless cross cube.

There are many Kongming lock toys, with different shapes and internal structures, and they are generally easy to disassemble and difficult to assemble.When assembling, you need to observe carefully, think carefully, and analyze its internal structure.

It is good for brain development, flexible fingers, and is a good educational toy.

When traveling to 2022, Xiao Chuan deliberately watched the Shanghai World Expo on the Internet.

The Luban lock in the Shandong Pavilion of the Shanghai World Expo is composed of 2016 LED modules of 32 by 16 centimeters.

The huge Luban lock with a length, width and height of 5.3 meters can be regarded as a "landmark" symbol in the Shandong Pavilion.

From the appearance, the six equal-length strips are divided into three groups, and they are mortized and tenoned at 90 degrees to form 30 display surfaces, forming a complete movie clip, the scene of four seasons, the vigor of all things growing, and the elegant flying of white swans , all show the concept and beautiful vision of harmonious coexistence between man and nature.

More than 2000 LED modules of Lubansuo are controlled by a computer with 60 control chips. It takes a lot of complex calculations to achieve the beautiful picture effect accurately presented. This is actually a process that requires a lot of technical content.

How to assemble more than 2000 modules to form an overall image requires careful thinking to form an idea
The Luban lock in the Shandong Pavilion, under the magical and changing appearance, is a steel frame structure, and the circuit connections are concentrated inside.

It took a month to assemble the entire Luban lock.

At that time, Xiao Chuan was amazed. He spent dozens of yuan to buy a Luban lock on a certain treasure, and after several days of tinkering with it, he finally understood it.

Xiao Chuan smiled and said, "Okay, let me try."

Xiao Chuan didn't move the Luban lock on the table, but turned around the table, and then stretched out his hand to gently pull a wooden bar.

"Whoa."

The tightly stitched Luban lock fell apart, and eleven wooden strips fell onto the table.

Xiao Chuan pinched a wooden stick with two fingers, put it to his mouth, imitated the action of blowing on the muzzle of a gun, and said with a smile: "Master, you think it's okay?"

Gongshuchi turned pale with shock, and said, "Your Excellency is so smart."

Xiao Chuan said: "Patriarch Gongshu, I have a gadget. If the Patriarch can put it together well, I won't bother you anymore. If the Patriarch can't, can the Patriarch also come out to help King Jin and me build a new capital?"

Gong Shuchi said: "The things that adults admire must be novelty things, and the old man is willing to see and see."

Xiao Chuan took out a blueprint of "Alexander's Star" in the system space warehouse, which is a regular dodecahedron-shaped Rubik's cube with 30 movable parts.

"Patriarch, can you see if this dodecahedron cube can be made?"

Gongshuchi said: "My lord, as long as there are carpentry jobs with blueprints, the old clansmen can do it."

Gong Shuchi handed over the blueprint of the Rubik's Cube to his son, and within an hour, Gong Shuzhong returned with a colored Rubik's Cube.

Xiao Chuan took it over and saw that the twelve surfaces were smooth and even, better than those polished by machinery, and it turned very freely.

"The craftsmanship of the Gongshu family is truly unparalleled in the world!"

Xiao Chuan messed up the colors of the Rubik's Cube, then handed it to Gongshu Zhong and said: "Brother Gongshu, try to make a group of five star shapes rotate around the outermost vertex, so that it reaches five sides of the same color in each star shape." Surrounded, the star on the opposite side is also surrounded by the same color."

Gongshu Zhong tinkered with it for a stick of incense, sweating profusely, and didn't fight well, and finally smiled wryly: "A grown-up is talented, and a villain doesn't have a Rubik's Cube to see the secrets."

Xiao Chuan said in his heart: "The regular hexahedron Rubik's cube probably would have been studied by the ancients for a few days, not to mention the twelve-sided Rubik's cube I took out."

But he said: "Patriarch, why don't you try it too?"

Gongshu Chi smiled and said: "The child already has [-]% of the skills of the old man, so the old man will not make a fool of himself, and is willing to go out to help adults."

Xiao Chuan was overjoyed and said, "Great, besides saddles and stirrups, I also have some equipment blueprints, please help the Gongshu family to make them."

When Gongshuchi and his son saw those exquisitely designed bed crossbows of the Song Dynasty, they immediately became interested, and when they saw the blueprints of later muskets, they were shocked by Xiao Chuan.

Gongshuchi held the blueprint, his hands trembling, and said, "Such a musket weighing more than ten kilograms can shoot hundreds of meters and kill the enemy?"

Xiao Chuan said: "As long as someone develops gunpowder, he can kill people invisible."

Chang Sun Sheng said with emotion: "This is the devil that will change the course of the war."

Since the system doesn't allow me to use modern weapons, I'll make them myself.

When parting, Xiao Chuan urged Gongshu's family to keep military secrets. Gongshuchi naturally agreed, and sent his son Gongshuzhong to take dozens of family children to the Shishan military camp. From now on, Gongshu's family will be tied to Xiao Chuan.

Rest for two days, and the pro-team set up camp.

Everyone came up to the horses, and with the new Takahashi saddle and iron stirrups, riding was much more comfortable than before, and Dugu Cheng's equestrian skills also improved a lot.

After trekking through mountains and rivers, it took more than a day, and the marriage team finally arrived at Tucheng, a small border city between Dazhou and Turks.

The city wall of Tucheng is less than two feet high, and there are [-] soldiers stationed there. Although their armor is torn and their beards are unshaven, they look murderous, and they look like they have been fighting for a long time.

The soldiers living in the frontier are the same as the local residents, they all have a tough personality, and they lick blood with their knives, otherwise it would be difficult to live until tomorrow.

The guard of Tucheng settled Princess Qianjin's horse and horse guards and the Turkic envoys, and then the guard whispered: "Master Dugu, Mr. Changsun, a friend wants to see you."

The guards took Xiao Chuan and Changsun Sheng to a room next to them. In the room sat a Han Chinese man in his thirties who was dressed in a Turkic costume and had a handsome appearance.

"Brother Shi, you can't recognize someone in this outfit."

Shi Wansui laughed loudly and said, "Hahaha, brother Dugu, this Turkic attire can catch them by surprise."

"Brother Shi, how is the harvest this time?"

"Brother, I asked my brothers to dress up as Western Turks. We raided two Turkic tribes and robbed more than 1000 war horses."

"That's great, so we have two thousand cavalry."

"Afraid of attracting the attention of the Turkic people, Yu Juluo and the others hid fifty miles outside the Tucheng."

"Tomorrow, someone will ask the Turkic envoy to report back, and then we can flex our muscles and muddy the Turkic pool."
