Standalone Lord: My Dilapidated Manor Can Be Upgraded

[Infrastructure + cool writing + time travel + system + no female protagonist] When programmer Chen Yu stayed up late debugging "Manor Era", he accidentally entered the stand-alone management world he developed and became the lord of a run-down manor on the border. The bound system is exactly the test version he wrote - it can fine-tune resource efficiency and infrastructure construction time, but it has strict upper limits and does not engage in mindless cheating. At the beginning, there is only a leaky wooden house and 3 acres of thin fields. The food is only enough for 5 people for 3 days. There are also "problem NPCs" such as the old housekeeper who has been wronged, the peasant woman who coughs up blood, and the decadent lame blacksmith. Chen Yu did not take the road of fighting for hegemony. Instead, he set the rule of "10% low tax, full exemption in disaster years", relied on code fine-tuning to gain the trust of NPCs, and exchanged sincerity for NPC trust. From accepting fleeing farmers to attracting winemakers, doctors, and teachers; from 1 square kilometer of land to a town of 50 square kilometers; from lack of food and clothing to building textile workshops, medical stations, schools, and squares. There are no deep grudges, only down-to-earth management and warm images - everyone who comes here can find stability and dignity. [Infrastructure + upgrade flow + group portrait + no heroine + time travel + system] What Chen Yu wants to do is to turn this dilapidated manor into the warmest paradise in the game world.
