In the age of interstellar navigation, human civilization spread across the galaxy, giant corporations controlled the star field, and classes were solidified. Lin Yuanhang, a low-level scavenger, accidentally stumbled upon the wreckage of an ancient battleship during a job and awakened a super construction system called "Tiangong".
This is the ultimate creative AI from a lost civilization, capable of analyzing all matter, optimizing all structures, and creating all machinery.
Starting from modifying his own small broken ship, to building the first "hive" drone that surpasses human technology, and then building a mobile fortress that can compete with the interstellar fleet. Lin Yuanhang used "heaven's workmanship" to turn garbage into artifacts and cast scrap iron into gods.
When giant corporations try to monopolize his technology, and when interstellar empires try to seize his creations, what they face is a mechanical god who rises from the ruins and arms himself with gears and circuits. Lin Yuanhang and the mechanical army he created will redefine the order of the universe.
