Rebirth of Wu Ba Spring and Autumn

"Wait a minute!"

Qingji stepped forward and stopped the young man.

The servants looked at Qingji quite dissatisfied.

Qingji took out a token from his bosom, and wrote "Yushitai" in three bird seal characters, which are the characters of Wu State, which are different from the Huaxia countries.

"doctor!"

The servants saluted again and again.

"Stand back first, I want to question him a few words."

"promise!"

The people at Yushitai are basically responsible for monitoring the court and various places, and they are the most difficult type of people in Wu.

How dare the servants offend Qingji?

When the errands left, the young man looked at Qingji with some doubts.

"Little brother, how do you sell these things?"

The young man bowed to Qingji and said: "To tell you the truth, doctor, you are a nobleman, and you may not need these things."

"This is 'moment'. It consists of a handle and wings, which are perpendicular to each other and form a right angle. The shorter handle is one foot, and it is mainly used for measurement."

"The length of the rectangular wing is variable, and the longest is twice as long as the handle of the ruler. It is mainly used to measure right angles and balance lines."

"Generally speaking, carpenters can measure right angles, planes, lengths and even lines of balance by moment."

After a pause, he put down the "moment" in his hand again, picked up the hook on one side, and introduced: "This is the 'hook strong', which can be fired hundreds of steps through the special crossbow below."

"Thick ones can be used to pull the warship. If the two countries are at war, the enemy's ship retreats and can be hooked. If the enemy's ship attacks, it can be pushed back. The thinner one can be used for climbing. It is most suitable for taking cities quietly. gone."

"Of course, this hook strength is still in the experimental stage, and it may not be able to achieve this effect."

"..."

Qingji suddenly became interested.

"Let's talk about something else."

"promise!"

At this time, Xi Shi and Zheng Dan, who were still shopping for some rouge, gouache, and beautiful jewelry not far away, also came to Qingji's side, looking very curiously at the young man who chatted with Qingji.

I saw him take out another inconspicuous key.

"What's so strange about this?"

Zheng Dan pouted.

"Little lady, don't underestimate this key. It is different from ordinary locks and keys. There are subtle mechanisms inside. With it, the warehouse will basically not need to be guarded in the future. This is exactly what you need, doctor."

It is worth mentioning that there was a simple lock and key in the time of King Mu of Zhou, which was shaped like a fish.

And the key improved by this person in front of him is shaped like a lizard, with a mechanism inside, which seems to be opened only with a key, and can replace human guards.

Qing Ji took a glance, and saw that the objects in front of this person were basically strange things to others.

He must have invented it.

Qingji can recognize these objects.

What is it?
The moment is the curved ruler.

Wheelsmiths stick to their rules to measure the radius of the world.

Rules, that is, compasses and rulers.

In addition to the curved ruler, there is also the ink fountain, which is a tool used by carpenters to play strings.

The ink fountain uses a bucket-shaped box to store ink. One end of the thread passes through the ink hole for dyeing, and the end of the dyed thread is a small wooden hook.

There is no need to talk about the rest of the locks and keys, hooks, saws and the like.

The most eye-catching thing is the vividly carved wooden magpie.

"Sir, how do you sell this wooden magpie?"

Zheng Dan asked with great interest.

"At least... ten taels of gold."

The man said tentatively.

"what!"

Zheng Dan suddenly frowned slightly, pointed at the wooden magpie, and said angrily: "Sir, are you bullying me, a woman who knows nothing?"

"A mere wooden magpie, no matter how exquisite your craftsmanship is and how well you carve it, how can it be worth twelve taels of gold?"

The young man shook his head and said, "My lady doesn't know something. This wooden magpie is very different from other wooden objects. It is not only beautiful on the outside, but also has a universe inside!"

"It took me five years and repeated experiments before I developed and produced this wooden magpie."

"This wooden magpie can fly in the sky for more than three days without falling. I originally wanted to dedicate it to the King of Wu, but now I'm already cash-strapped. How can I not justify selling you ten taels of gold?"

Upon hearing this, Zheng Dan rolled his eyes angrily, and said, "Hmph, bragging!"

"You little wooden magpie, how can you fly? You can fly for three days!"

Being so provoked by Zheng Dan, the man gritted his teeth in hatred, stared at him, stomped his feet and said, "If you don't believe me, young woman, seeing is believing!"

The man squatted down immediately, and drew a thin rope from the tail of the wooden magpie. After pulling it, he let go of the wooden magpie, and the wooden magpie with the mechanical principle inside rose into the air and flew into the air.

The man took the next step without rushing, pulling the string rhythmically, as if to provide power for the wooden magpie...

"Fly...it really flew!"

Including Xi Shi and Zheng Dan, the people in the market couldn't help being dumbfounded and gathered around to watch.

This flying wood magpie is very rare after all.

At this time, if Qingji still can't recognize the identity of the man in front of him, he is blind.

When he saw these objects, Qingji had already recognized them.

The other party is none other than the famous originator of civil construction, carpenter, and opera troupe in history——

Gongshuban!
To change to a well-known popular name, he is Lu Ban!
This person's surname is Ji, Gongshu's family name, Ban, style name Yizhi, people call him Gongshu Pan, Gongshu Pan, Banshu, respectfully call him Gongshuzi, also known as Lu Pan or Lu Ban, and is commonly called "Lu Ban".

Luban covered a wide range of fields. He was good at inventions in the fields of architecture, sculpture, agriculture, weapons, etc., which were directly or indirectly related to the carpentry industry.

"Lunheng" contains that Lu Ban invented a wooden carriage with built-in mechanisms, which can move by itself.

In addition, a wooden man was built, which can not only walk by itself, but also carry people, which is very wonderful.

This is still a master of mechanical engineering!
Whether it is the flying wooden magpie that Qingji saw, or the legendary wooden carriage and wooden man, it definitely belongs to ancient black technology.

Without electricity, fuel, or hydrogen as a power source, how does the wood magpie fly?

How does the wooden carriage move by itself?
Based on mechanical principles alone, isn't that a proper black technology?
Qingji never denies that the ancients were very smart and open their minds.

For example, Lu Ban in front of him seems to be looking at the birds flying in the sky, and also hopes to invent something that can fly in the sky.

Wooden magpie was born from this.

Once, when Luban went into the deep mountain to cut trees, he accidentally slipped and his hand was cut by a leaf of a weed, which oozes blood.

He took off the leaf and touched it lightly. It turned out that there were sharp teeth on both sides of the leaf. He used these densely packed small teeth to stroke the back of his hand lightly, and actually cut a hole.

Lu Ban was inspired by this, and after many experiments, he finally invented the sharp saw, which greatly improved the work efficiency.
