Glycolic Acid
In the past, there were aliens who were good at making strange things. In the workshop, I focused on research, and at the age of sixty, I studied the art of glycolic acid.

It is in the method of pharmaceuticals, carefully explore. Examine the nature of raw materials, examine the small temperature, and seek the right ratio. It is often accompanied by a fire all day long, and it is difficult to read alchemy at night. Think of ways to improve, so that the quality of glycolic acid is pure and effective.

Every time you get a method, you must test it yourself. Or try it on utensils and observe its changes; or use it in real objects and observe its efficacy. If it doesn't work, you will not be discouraged or impatient, and repeatedly investigate until it is appropriate.

Because of this, the glycolic acid it produces has gradually become famous. People from all over the world hear its name and ask for it, and those who use it praise it. The art of aliens is passed down in the neighborhood, and it is praised by everyone. It is also for those who study this thing in later generations, leaving many ways to learn.
