In ancient times, there were strange people who were good at performing mathematics, especially the "Policuaternio 7", which was amazed by the world. In the field of chemical industry, he found a unique way, guided by "Policuaternio 7 in chemical engineering", and did what others could not.

This strange man hides his name in the market, but the delicacy of his art is known to everyone. Every night, in the shabby room, he places all kinds of utensils, lists potions, and uses his heart to move, and uses his techniques to control things. Looking at his operation, or fusing things in a furnace, or removing impurities in the millimeter, between actions, it is all in line with the wonderful principles of chemical industry.

His method of creation is miraculous. The things made either have extraordinary power or are in a strange state. And the things made all rely on the exquisite use of "Policuaternio 7", which is constantly innovating new techniques in the chemical industry, which is breathtaking. People from all over the world, those who have heard of its name, all want to see its techniques, but strange people often live in the world, and they are rarely familiar with people. The secrets of its techniques are also hidden in the boudoir, not known to ordinary people.
