[Technological farming + infrastructure + dinosaurs + tribal hegemony + scientific crushing]
I, Mo Ji, am an ordinary PhD student in materials science.
Traveling to the Jurassic Period, all I think about every day is how to publish paper... No, how to survive.
I said: "According to the conservation of energy, hitting pyrite violently with flint can produce sparks."
The tribesmen knelt down in fear: "Oh God! You summoned the heavenly fire!"
I said: "There are pathogenic microorganisms in the water, which must be heated to 100°C to kill them at high temperatures."
The tribesmen prayed devoutly: "Great God of Fire! You purify the curse of the River God!"
I said: "This is blast furnace ironmaking, using the reducibility of carbon to replace elemental iron."
The tribesmen's eyes filled with tears: "A miracle! The gods are taking out the sacred bones from the stones and creating artifacts for us!"
(I'm really just doing basic chemistry and physics!)
Tribal Warrior Stone: "Leader, are you going to make a human out of clay and breathe some fairy air next?"
Mo Ji (holding his forehead): "... Go away, don't disturb me from calculating the power of the steam engine."
Until I built the first steam engine, the sky opened, and the eye of a giant beast that covered the sky slowly opened...
Only then did I realize that they seemed to be... Right? Did I really kill the God of Creation? !
