Coming out of Changle Palace, Wang Mang sighed and laughed at himself, Chunyu Chang is so lucky!

Although it seems that Chunyu Chang was not touched at all this time, it at least made him lose a few points in Wang Zhengjun's heart.

Therefore, after this battle, Wang Mang did not lose anything!

Not only did he show his presence in front of Wang Zhengjun, but he also showed his familiarity in front of Liu Ao. Not only that, Wang Mang also kept excusing Liu Ao.

As long as Liu Ao is not an ungrateful person, Wang Mang's operation can actually be considered a success!

After all, to truly defeat an enemy who is far more powerful than oneself, it will take a long period of accumulation and qualitative changes to succeed.

Although there are stories like that where a few words can bring someone down, it seems unrealistic for Wang Mang.

After all, Liu Ao did not favor Wang Mang, so Wang Mang's words were just the words of an ordinary person in Liu Ao's ears.

Expecting an ordinary speech to overthrow Chun Yuchang, who has already won the Holy Heart, is simply a fool's errand!

After leaving Changle Palace, Wang Mang returned to his home. Now he still has one more important thing to do.

Liu Xin was obsessed with the art of cutting circles, so he must have needed an accurate measuring tool.

As a time traveler, Wang Mang, although some theoretical knowledge is not comprehensive enough, but in terms of knowledge, he can definitely crush the people of the Han Dynasty.

Therefore, Wang Mang used his knowledge before time travel to create a tool for Liu Xin that could accurately measure values.

And Wang Mang has already figured out what this tool is!

That is the famous vernier caliper!

If Wang Mang remembers correctly, it seems that the cultural relics of the Xin Dynasty unearthed in later generations include a vernier caliper.

Now Wang Mang wants to build this vernier caliper, firstly to fulfill his promise to Liu Xin, and secondly to satisfy his own bad taste in history.

Think about it, two thousand years later, people once again discovered that the vernier caliper appeared more than two thousand years ago. What an exciting enjoyment it is!

Therefore, since there is a historical precedent, Wang Mang simply makes it a reality!

Only in this way can we live up to our identity as a time traveler!

After returning home, Wang Mang went to the craftsmen who were making vernier calipers according to his requirements.

Wang Mang felt proud as he watched the two craftsmen conscientiously making the world's first vernier caliper according to their own drawings!

"Are there any technical difficulties?"

After Wang Mang watched for a while, he asked the craftsman.

The craftsman who made the vernier caliper replied: "I have completely understood the principle of this thing. I just need to quench the scale of the main body of the ruler, and then I can try it out and check it according to the master's requirements."

Wang Mang was in a good mood when he heard the craftsman's confident answer, "If you can make this ruler exquisitely, I will reward you greatly!"

Wang Mang is not stingy with his rewards. A craftsman with such exquisite skills deserves a good reward from him.

The Han Dynasty inherited the Qin system, and while it valued agriculture and neglected commerce, it also despised craftsmen.

The important reason why the Qin and Han Dynasties implemented such a national policy was due to low grain output.

During the Qin Dynasty, in order to bring peace to the world, the successive kings of Qin respected Shang Yang's method and implemented the national policy of focusing on agriculture and suppressing business.

Its purpose is to increase food production and complete the most basic primitive accumulation, so as to accumulate strength and wipe out Liuhe!

During the Warring States Period, disputes between the seven kingdoms continued, and famous generals from each country emerged one after another.

But only Qin can dominate the world. This is not because the Qin people are so powerful, but because the Qin people have continuous logistical supplies for their troops.

Since ancient times, wars have been fought based on logistics. As long as the logistics are sufficient, even if there is no advantage for a while, as long as the energy consumption continues, the balance of victory will naturally shift towards the side with stronger logistics.

This is also the reason why after the fall of Qin, the Han Dynasty inherited the Qin system.

Firstly, it was because the Qin system was suitable for the new centralized dynasty, and secondly, it was because the new Han Dynasty was plagued by internal and external troubles, including chaos caused by kings with different surnames at home, and the Xiongnu's eager eyes outside.

Under such a tense situation, if the Central Dynasty wants to reverse the situation, it must find a way out from the most fundamental issue of food.

Therefore, the policy of focusing on agriculture and suppressing business and humble craftsmen naturally became the basic national policy of the Han Dynasty.

Its purpose is to provide the dynasty with a steady stream of food and ensure the foundation of the dynasty by elevating the status of farmers.

Later, with the rise of emerging nobles, land annexation brought more benefits. Therefore, no matter what the emperor thought, the policy of focusing on agriculture and suppressing business and humble craftsmen would not be abandoned by these nobles.

It is precisely because of the long-term implementation of this national policy that they have been able to occupy the top position of social resource distribution and maintain their own status and extravagant life.

Because farmers and craftsmen are honest people who are easiest to bully. These people are born as cows and horses. As long as they can be given a bite to eat and not allowed to breathe, they will work harder than cows and horses.

But if we give them a relatively relaxed environment and reduce their exploitation, they will have other ambitions and want to go further.

This is absolutely unacceptable to the nobles who have become accustomed to the life of superiors!

Therefore, as the dynasty continues to stand for a long time, the status of farmers and craftsmen will become increasingly humble.

At the same time, as the power of the nobles develops, their exploitation of land and wealth will become more intense. The reason is that the pride and luxury among these nobles are increasing, and the trend of comparison is becoming increasingly fierce.

In order to maintain their arrogant and luxurious aristocratic enjoyment, those who were sacrificed were naturally the farmers and craftsmen who worked hard to support the prosperity of this dynasty.

As a time traveler, Wang Mang naturally understands the shortcomings of the feudal dynasty, but now he is unable to change the status quo, so all he can do is to give these outstanding craftsmen certain material rewards within his own ability.

As for the vast majority of poor people, Wang Mang cannot take care of both, so he can only go with the flow and see what changes will happen in the future.

What Wang Mang has to do now is to hold on to his basic base and steadily climb up. Only after reaching a certain high position can Wang Mang be qualified to consider these issues.

Otherwise, his end will not be any better than that of the original Wang Mang in history.

Therefore, it is better to put away your overflowing compassion and manage the present well.

Wang Mang watched intently as the craftsman followed the process step by step to mark, polish, and finally quench and assemble the vernier caliper he designed.

After seeing that they had finished assembling the vernier caliper, Wang Mang couldn't help but get excited. He couldn't wait to take over the new vernier caliper and play with it carefully.

But the two craftsmen were still correcting the scales meticulously, so Wang Mang could only hold back his excitement for the time being and wait quietly for their final completion.

Soon, the two craftsmen completed the inspection.

One of the craftsmen respectfully held the shining golden vernier caliper and said: "The villain is finished, please check it."

Wang Mang took the vernier caliper in surprise, looked at the scale units on it, and moved the tabs on the vernier caliper, feeling extremely happy.

"Not bad, the craftsmanship is extremely exquisite! I like it very much, let's go and get the reward first."

Wang Mang praised the two craftsmen for their craftsmanship and rewarded them.

Looking at this shining golden vernier caliper, Wang Mang sighed, "This is the original color of bronze! Just like gold. Those green bronzes in later generations were actually oxidized because they were buried in the ground for too long.
Chapter completed!
