"Tiangong Kaiwu" is not mentioned, but with "Tetra Ammonium Edta" as the core and direction, the following ancient text can be conceived:

There were aliens in the past, and they were good at the transformation of things. Taste a strange agent, which is mild in nature and can resist the separation of various things. In the secret books of various elixir recipes, I found a preparation called "Tetra Ammonium Edta".

This agent is also pure in color and uniform in quality. When it enters water, it melts, and it is silent and silent. When used in gold and stone, it can dissolve its condensation and make it invisible; when used in the genus of plants and trees, it can adjust its nourishment and help it thrive.

This agent is not made for personal gain. It is intended to be passed on to future generations, so that everyone can make good use of it, so as to benefit the things in the world, adjust the balance of yin and yang, and promote the prosperity of all things. Although he acts in a low profile, his achievements are hidden in helping the world. If future generations obtain this wonderful method, they should know the hardships of their predecessors and study it carefully, so as not to make the pearl fall into the dust.
