Sheyan patiently explained to Jean, "Why did the government union only build four Noah's Arks with the entire strength of the human race? Because they don't know the specific situation of the disasters that are about to occur, so they can only device their plan according to the worst case scenario. Based on the information you provided, the Arks can withstand temperatures above 1000 degrees Celsius and 80 degrees Celsius below zero. They can also resist the pressure ten thousand meters underwater and carry the supply for fifty thousand people for five years. In reality, more than 90% of the design is a waste."
Sheyan sighed.
"Unfortunately, I have no way to tell the government the truth. First of all, why would they believe me? And even if they do believe me, sure, more people can be saved, but the more people that are saved, the difficulty...I mean, the power sent to correct the course of history will be greater too!"
