Border Lord's Production Counterattack

Li Fan, a young man from Shandong, died suddenly while working overtime and was reincarnated into a magical aristocratic family in a different world, becoming Van Fertio, the youngest son of Marquis Fertio. In this world, magic is respected. The nobles value the four elements of magic (fire, water, wind, and earth) that can fight and kill most, and the healing light magic. The production magic is regarded as the most rubbish existence - it consumes a lot of magic power, and the things created are not as useful as those made by ordinary craftsmen. Fan, who unexpectedly awakened the memory of his previous life when he was two years old, learned through the memory fragments of his original owner: six years later, he would be tested for the most unpopular talent in production magic, and then be rejected by his father. Finally, he would be sent to a shabby village on the border with no name to be a nominal lord. It was a barren land sandwiched between neighboring countries and the earldom, with only a few hundred villagers and no special products. The mountains to the north were inhabited by powerful monsters. But Li Fan didn't panic. In his previous life, he was a social worker who graduated from the 985 Mechanical Engineering Major and knew the modern industrial production system well. Production magic is trash in the eyes of others, but it is priceless in his eyes!
