(No System + genuinely useless protagonist + loosely reworked Have You Ever Seen a Bunny? plot + transmigration plot)
The river of time flows onward, holding countless causes and effects within it. The end of time is already set. Even if it is changed ahead of schedule, an unseen hand will secretly set the ending right again.
When you toy with time, time toys with you. Start by changing an uncaused beginning, and you will end by bringing about a predetermined consequence. Time and causality are both part of the Great Dao. The slightest meddling can lead to a completely different ending.
(This is my first time writing a novel, so updates will be slow and sporadic. Have You Ever Seen a Bunny? has too much angst. I’m mainly writing this for myself xwx.)
