Chapter 3503: The power of god
The industrial revolution in the middle, the steam engine, the internal combustion engine, etc., are all like this!
Including the top-notch outer space rockets, they all operate by "boiling water".
As a result, some pessimistic people say that if human beings do not get rid of the boiling water, the earth will always be the only home:
Human beings cannot explore any habitable planet and can only die on the earth.
"Uh."
Li Yun suddenly thought of a question and looked at Xiao Su: "In ancient times, was the starry sky the same as it is now?"
"Otherwise?" Xiao Su started eating candy again, knowing that Li Yun would not give her so many lollipops.
"So the wars, love, friendship between gods, including fairies and monsters, all happen on the earth?"
"Humph."
Shengzi Xiaosu answered with a grunt, yes!
