"Wait!"

Qingji stepped forward and stopped the young man.

The tolerance people looked at Qingji with dissatisfaction.

Qingji took out a token from his bosom, and wrote "Yushitai" with three bird seal characters, which is the script of Wu State, which is different from the Chinese countries.

"Doctor!"

The bearers saluted one after another.

"Wait for you to stand down first, I'm going to interrogate him."

"No!"

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

Where do the tolerances dare to offend Qingji?

When the men left, the young man looked at Qingji with some surprise.

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

The young man bowed to Qingji and said, "Don't hide it from the doctor, you are a nobleman, and you may not be able to use these objects." ”

"This is a 'moment', and its rectangular handle and rectangular wing are composed of a rectangular handle and a rectangular wing, which are perpendicular to each other at right angles, and the rectangular shank is shorter than one foot, mainly for the purpose of measurement."

"The length of the rectangular wing is uncertain, and the longest is twice the size of the shank, which is mainly used for measuring right angles and balance lines."

"Generally speaking, carpentry can measure right angles, planes, lengths and even balance lines."

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

"The rough one can drag the warship, and if the two countries are at war, the enemy ship can hook it if it retreats, and if the enemy ship attacks, push it back. It can be used as a climb, and it is most suitable to take the city quietly. ”

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

“……”

Qingji was interested for a while.

"Let's talk about something else."

"No!"

At this time, Xi Shi and Zheng Dan, who were originally buying some rouge gouache and beautiful jewelry not far away, also came to Qingji's side, and looked at the young man who was talking to Qingji very curiously.

I saw that he took out another inconspicuous key.

"What's so strange about that?"

Zheng Dan pouted.

"Don't despise this key, little woman, it's different from ordinary keys, and there are subtle mechanisms in it. With it, there is basically no need for guards in the treasury in the future, which is exactly what you need, doctor. ”

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

The lock and key improved by this person in front of him are shaped like a cricket, with a mechanism inside, which seems to be opened by a key, and can replace the person's guard.

Qing Ji glanced at it, and saw that the objects in front of this person were basically strange things for others.

He must have invented it.

And these objects can be recognized.

What is it?

Moment is the curved ruler.

The wheelsmith adheres to its rules to measure the square circle of the world.

Rules, i.e. compasses and rulers.

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

The ink fountain is stored in a bucket-shaped box, and the thread is dyed from one end through the ink hole, and the end of the dyed rope is a small wooden hook.

The rest of the locks, keys, hooks, saws and the like need not to be mentioned.

The most eye-catching thing is the lifelike wooden magpie.

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

Zheng Dan asked with interest.

"At least...... Ten taels of gold. ”

The man said tentatively.

"What!"

Zheng Dan frowned slightly, pointed to the wooden magpie, and said angrily: "Sir, aren't you bullying me for being a woman who doesn't know the goods." ”

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

The young man shook his head and said, "The little woman doesn't know anything. In this wooden magpie, it is very different from other wooden objects, not only the appearance is exquisite, but also the inside! ”

"It took five years and repeated experiments to develop and produce this magpie."

"This magpie can fly in the sky for more than three days without setting. Originally, I wanted to dedicate it to King Wu, but now I have a shy bag and sell you ten taels of gold, how can I say it? ”

Hearing this, Zheng Dan rolled his eyes angrily and said, "Hmph, bragging!" ”

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

Being provoked by Zheng Dan like this, the man gritted his teeth with hatred, glared, stomped his feet and said, "If the little woman doesn't believe it, seeing is believing!" ”

The man immediately squatted down, pulled a thin rope on the tail of the wooden magpie and pulled it, and after dragging it, he let go of the wooden magpie, and the wooden magpie with mechanical principles inside took off into the air and flew into the air.

The man was not slow in the next step, pulling the string rhythmically, as if he was providing power for the wooden magpie......

"Fly...... It's really flying! ”

Including Xi Shi and Zheng Dan, the people in the market couldn't help but be dumbfounded and watched one after another.

This can fly wood magpie, after all, is very rare.

At this time, if Qingji can't recognize the identity of the man in front of him, he will have no eyes.

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

The other party is none other than the famous originator of civil engineering architecture, carpenter, and opera troupe in history-

Lose class!

To change a well-known popular name, he is Luban!

This person's surname is Ji, the name of the class, the name of the class, the word is Zhi, the person is called the public loser, the public loses, the class loses, the honorific title of the public loser, also known as Lupan or Luban, commonly known as "Luban".

Lu Ban is involved in a wide range of fields, he is good at inventions in the fields of architecture, carving, agriculture, weapons, etc., which are directly or indirectly related to the carpenter industry.

According to the "Treatise on Balance", Lu Ban invented a wooden carriage with a hidden mechanism, which can move on its own.

In addition, there is another wooden figure, which can not only walk on its own, but also carry people, which is extremely 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, no fuel, and no hydrogen as an energy source, how did the magpie fly?

How does a wooden carriage move on its own?

Isn't that a proper black technology based on mechanical principles alone?

Qingji never denies that the ancients were very smart and would open their minds.

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

The wooden magpie was born.

Once, when Lu Ban went into the mountains to cut down trees, he accidentally slipped under his feet, and his hand was cut by the leaves of a wild grass, oozing blood.

He picked off the leaf and touched it gently, it turned out that there were sharp teeth on both sides of the leaf, and he used these dense small teeth to lightly scratch the back of his hand, and actually cut a hole.

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