The "lattice war" at the end of the century ended with the uncontrolled detonation of the stratigraphic resonance bomb.
The geomagnetic reversal, volcanic eruptions, and radioactive dust blanket the sky.
The sun's rays are filtered into a dim yellow by the gray mantle, the oceans become acidified, plants become extinct, and the old world collapses.
After this catastrophe that lasted for hundreds of years, civilization was reduced to wasteland.
Technology has declined to its primitive stage, and faith and violence have become the new order.
Cheng Yuan, a former doctor of materials science, woke up in this radioactive wasteland.
He took his infant daughter and pushed an oxygen cart to look for life in the endless ashes of the wasteland.
He is neither a savior nor a hero.
He is calm, calculating, paranoid, and only believes in knowledge and logic.
But for my daughter, for the little bit of "humanity" that is still not covered by ashes,
He began to use abandoned technological remains, corroded instruments, scrapped cores...
Rebuild the magnetic field, purify the air, and grow the first piece of edible mycelium.
He wants to erect a holy monument of reason in this wasteland.
Catastrophes can destroy civilization, but they cannot destroy thinking.
——Reason is the last belief of mankind.
