Rotten Wood Three Days

The protagonist is not a time traveler, but an 'ordinary person' who has lived for thirty thousand years. He has no magic, but his very existence is a 'bug'. Throughout the long history, all his relatives and friends have turned to dust, but he cannot die due to some 'logical loophole'. Core conflict: This world is not composed of matter, but of 'narrative'. The so-called 'Heavenly Dao' is nothing more than an old, dying operating system.
