Building Infrastructure in Another World (Book Transmigration)

This story is also known as #Building Infrastructure, Not Boyfriends : )# You Qian transmigrated into a book and became the son of its universally adored protagonist. Unfortunately, the universally adored protagonist died young, leaving behind a horde of admirers who all cried and fought to raise his only son. You Qian, knowing his father was an incubus: ... Faced with all these powerful people, You Qian was at his wits' end. He insisted on returning to his biological father's territory to inherit his estate. While everyone looked like they wanted to say something but couldn't, You Qian rode back to his territory in a luxurious, fully equipped carriage. He expected to find a thriving, prosperous place. Instead, when he stepped down, he saw a scene of crumbling ruins. The ragged, emaciated slaves saw him, panicked, and scattered like startled birds and beasts. You Qian: ... The most valuable thing in the territory was the carriage he'd brought back. The manor's front gate had been broken for three years, and the butler wept bitterly. Looking at the gate hanging by a thread, You Qian realized this was a serious problem. On his first night in the territory, You Qian stared silently at the hard, black bread on his plate. Then he learned that if he wanted a bath, he wouldn't be able to eat hot food for the next month. You Qian patted his chest. Fortunately, I have a System. * Ever since the great war between the races, the continent of Kamodin had been engulfed in endless conflict. Kings and nobles reveled in debauchery, while the weaker races went with the flow, constantly on the brink of extinction. Then, in the barren lands at the continent's far north, a demon lord appeared. They say that in his territory, minotaurs and dwarves alike could work alongside humans, and everyone got three meals a day! People lived in spacious homes with an everlasting "sun," and even the slaves' shacks kept out the wind and rain. And all you had to do to enter this territory was offer your soul to the lord. Demon Lord You Qian: I only asked for your souls... not your bodies! Fur-loving You Qian grumbled as he held the little wolf cub the System had dumped on him to raise. He only loved fluffy things, not people, thank you very much. Later, he learned that the little wolf cub he'd raised was actually the Beastfolk King. Looking at the fluffy ears on top of the man's head, You Qian: ... * The most revered pope on the continent of Kamodin once prophesied: [When the Child of Light descends, he will ascend the throne. His profound gaze will fall upon the ignorant masses, and he will spread wisdom throughout the world.] You Qian: Thanks, but no thanks. Knowledge changes fate, and technology changes the world.
