The Gods Keep the Wilderness in Captivity, and I Overthrow the Divine Palace with Ordinary Fire

Traveling through the wild wilderness, the human race has become a flesh and blood sacrifice raised in captivity by alien races! For thousands of years, the Nine Heavens alien species have proclaimed themselves gods, controlling life and death in the wilderness. They regard humans as pigs and dogs, offering sacrifices year after year and enslaving them from generation to generation. Chen Xuan, a top science student in modern times, traveled through time and became a human boy who was about to sacrifice to heaven. There is no system, no skills, no innate abilities. Only with thousands of years of human scientific civilization heritage! Sound wave resonance, hunting unsolvable wild beasts! The black powder exploded, shattering the majesty of the gods! Civil engineering works, hot weapons innovation, tactical army management, and civilization iteration! Will the alien race suppress my human race for ten thousand years? Then I will use the fire of mortal technology to ignite the wilderness! Break slavery! Kill the powerful! Defeat all the false gods in the Nine Heavens! From now on—— The human race is not a sacrifice, the common people have their own destiny!
