Bromo Tube
"Bromo Tube"
I have heard that there was a foreign object in ancient times, called Bromo Tube. Its shape is strange, and its material is special.
At the beginning, no one knew its use, only to see that its length is not full of feet, its diameter is a few inches, and if the texture of the whole body is naturally formed, there is a faint radiance.
Sometimes there are wise people who devote themselves to studying. Observe its structure and think about its mechanism. Or put water and fire to observe its changes; or try various objects to explore its reaction.
After months and years, there is finally something. Knowing the Bromo tube can be used to measure the change of yin and yang and identify the properties of objects. When you encounter the sun, you will be bright, and when you encounter the yin, you will be dark. In all kinds of experiments, you can be a guide.
Everyone is amazed when they get this wonderful thing. Taking Bromo tube as a treasure is beneficial to all things. Or it is used to identify herbs to prevent accidental mining; or it is used to investigate ore veins to clarify the advantages and disadvantages.
Since then, the name of Bromo tube has been passed down in all directions, used by everyone, and it has helped a lot. It has become a good story for a while.
