Counterclockwise War

Lin Xu didn't know what was happening in the world. The clock is spinning counterclockwise, time is constantly going backwards, and everything that has happened is replayed before our eyes one by one. The rules in the reverse time world have been redefined. Is existence really reasonable? What is the butterfly effect? Or is it chaos? What does the "truth" mean that appears in his mind again and again? If we could go back in time, could everything really change?
