Dressed as a Runaway Slave, I Relied on Magic to Farm and Ascend to the Throne

[Western fantasy, time travel, magic farming, territory management, infrastructure, no CP, big heroine] On her first day as a runaway slave, Su Fu carried the slave brand and was taken to the most dangerous Black Thorn Mine in the Elvia continent. Once the branding takes effect, she will be found by her slave master. If she escapes into the Blackthorn Wasteland, she will die from pollution, hunger, and monsters again. Everyone said that no food could be grown in this wasteland. Su Fu awakened the Spring Breathing Technique in the scorched earth. She made moon wheat grow out of the dead soil, made the sewage ditches covered with pure water moss, made the black vines entangle the slave hunting dogs, and also made the escaped slaves who had been suppressed by the magic shackles for many years pick up their magic again. The nobles blocked Yantie and tried to force her to bow her head. The grain merchants would destroy the fields and cut off the grain, hoping that she would starve to death. In the name of purification, the church will send her and the entire free village to the stake. Sophie only did one thing. Grow grain, build canals, refine medicine, and build cities. But as the wasteland grew green again, she gradually discovered that there was a more terrifying secret hidden behind the pollution of the Blackthorn Wasteland. Why does the never-extinguishing solar furnace in the capital require countless slave brands to maintain? How many lives are buried in the prosperity that the kingdom talks about? Until the earl led the mage army to attack the border, forcing her to hand over the land, magic plants and all escaped slaves. Su Fu stood in front of Liberty City and raised her hand to wake up the sleeping earth line formation. "Those who want to arrest me should first ask if this land will answer."
