When Ancestor Entropy's will encroached on the galaxy, Li Xi changed from a mine slave to a gravekeeper in a civilized cemetery. The spiritual veins of the Xuantian Sect, the mechanical ark of the divine religion, the remains of the elves' mother tree... The tombstones of billions of dead civilizations were used to forge his throne. Using the star core as his sword and the entropic ice as his armor, he tore through the Return to Era, and under the guidance of his sister Li Yue's mechanical teardrops, he ferried the embers of civilization in the abyss of heat death. But every time a star wakes up, a new paradox is carved on the entropy scale: sowing hope leads to plunder, rewriting genes leads to mutations, reversing time and detonating collapse... At the end of the fierce battle in the cemetery of the heavens, he will use himself as a monument to ring the final bell on the cliff of the universe with 90% entropy.
