And I help the emperor to implement the coin. As a woman, my younger martial sister is more careful and suitable to assist in the implementation of the method of measurement. "

Hearing the words of enlightenment, Shennong nodded and said, "the holy master is wise. It is indeed the most secure way to implement these two methods according to the method said by the Taoist priest, and will not bring any inconvenience to the human race."

The enlightenment said: "I and my younger martial sister just help from it. Everything needs to be handled by the emperor. Before I came here, the teacher gave me coins and measurement molds, and asked me to give them to the emperor to make them, and then promote the world."

The enlightenment took out a jade coin and a jade ruler from him and handed them to the emperor. These two things were carved by Kunpeng with ordinary jade before he left. The jade ruler is based on the "Jiutian Yuanyang merit ruler" and is engraved with the scale of future generations. The jade coin is based on the later copper coin, which is round as a whole with a square hole in the middle.

Shennong took over the two items and watched them carefully. Yuqian said that it was a kind of currency and there was nothing incomprehensible, but the jade ruler made Shennong a little confused. So he asked, "Taoist priest, I can understand the jade money, but I can't figure out what the jade ruler does and how to use it. I hope you can explain it."

The enlightenment smiled and said, "it's normal that the emperor can't figure out the use method and function of this jade ruler. When the teacher took it out at the beginning, I knew nothing about it like the emperor. Later, the teacher explained it. I just understood the use method and detailed function of this object."

The enlightenment paused for a moment, and then continued: "The jade ruler is only a basic measuring tool, which can evolve into many kinds. It does not specify the shape or pattern. The teacher once said that human wisdom is infinite, and the jade ruler is only a basic measuring tool for the emperor. The engraved degree on the ruler is the basis of measurement. Of course, if the emperor thinks there is something wrong with the scale, he can modify it by himself In this way, the emperor can formulate different measuring tools according to different requirements. For example, he can use rope as material and use this ruler as the standard to make measuring tools of different lengths to measure objects of different sizes and shapes. "
