Assembly Line Alchemy, I'm Doing Industrial Upgrading in the Holy Land

Tianyan Holy Land, a poor ancient holy land. It has the name of Holy Land, but even the third-rate sects don't take it seriously. Jiang Yu traveled through time and became the Lord of the Holy Land. After some investigation, he discovered that although this world has a high level of power, it is extremely backward economically. So he seized the opportunity and quickly introduced the assembly line alchemy method. Drastic reforms were carried out on the Danding Hall, the only remaining pillar of the Holy Land. The effect was sensational throughout the Holy Land. … In other fields closely related to "immortality", Jiang Yu is not to be outdone. Spiritual stone industry, weapon refining industry, talisman industry, formation industry, animal taming industry... One industry after another was discovered by Jiang Yu and completed as quickly as possible. Unknowingly, Tianyan Holy Land's business spread all over the world.
