Quality Conservation: Jian'an's Wet Dream

Lu Shiyan, a modern physics college student, accidentally traveled through time and space during a space-time experiment and fell into the chaotic battlefield of the Three Kingdoms. He was rescued by the unfavored Prince Jing, Xiao Jin, and became the most special counselor around this troubled prince. He understands military training, tactics, and the general trend of the world, and he also understands an iron law that no one knows - cause and effect in time and space, and conservation of total quantity. He can save a city, but he cannot change the fate of the country; He can win a battle, but he cannot stop the general trend; He can change the details against the odds, but he can't escape the final balance. He thought he was a variable, but he was just a link in a closed loop. From the lonely camp in northern Xinjiang to the chess game in the world, From life and death to the fateful end, He spent his life proving: Some encounters are destined; some staying together is conservation.
