The Happiness System of 1.4 Billion Citizens

I traveled through time and became a good-for-nothing lord of the Principality of Byron. I was hit by a blacksmith at the beginning and suffered a concussion. I was bound to the [Happiness System of 1.4 Billion citizens], and the loyalty of the subjects was -99. If I didn't improve my favor for seven days, the subjects rushed into the castle and stewed me! The original owner bullied men and women, and made the people of Greystone Town in the north miserable. Even the loyalty of the personal knights was only 1 - I don't have anyone around me? Winter is coming, with food shortages, extreme cold, and night attacks from monsters. The people will either freeze to death or starve to death, or they will come to chop me with knives! Others rely on magic knights to become lords, but I rely on summoning earth puppets to dig ditches, improve fireplaces, and use civil engineering knowledge to build infrastructure! "Lord, the monster is coming!" "Why panic? Look at the defensive wall I built with magic energy cement, and let them hit their heads and bleed!" "Lord, the food store is at the bottom!" "Don't worry, my improved magic rye has tripled its yield and will be enough for winter!" From the good-for-nothing lord that everyone wants to kill, to the infrastructure maniac that the refugees in the north are rushing to defect to, watch me use my hoe and shovel to carve out a kingdom on the frozen soil that even the dragons dare not mess with! "Who said that lords must rely on magic? My people are fed and clothed, which is the most powerful magic!"
