In the hot magma, there is a transparent country established by the refugees who resisted the war - the Earth Kingdom. Counting from the moment it escaped underground, the Earth Kingdom has existed for more than 180 years, retaining the fire of human natural science. At that time, the people of the Earth Kingdom would not have thought that "Embryo No. 439", Which was thrown into the magma as an experimental failure, could change the fate of the Earth Kingdom that was about to be swallowed by the mantle. No one would have thought that the geological genius codenamed "Shell" who suddenly appeared in the Earth Kingdom would change the fate of all mankind. The shells let the people of the Earth Kingdom know that the four unsolved mysteries of the Earth Kingdom point to a certain end point - the answer to the ultimate question of geology, an epitome of "that sentence". "That sentence" is part of the truth of the human world, and knowing the complete truth requires paying a price, an irreparable price. The fate of mankind will usher in a predetermined ending at the moment they make a choice.
