In 2031, the brain-dead Lin Xian returned to the late Han Dynasty with a second-hand AI chip. Inside the chip lives "Lucky Boy" - a ball of light that has all the knowledge before 2027 but can only respond passively. It calculated the loss of food and grass in the Battle of Guandu, the probability of east wind in Chibi, and even calculated that Guo Jia had eight years left to live.
What cannot be calculated is: why a person who wants to live chooses death again and again.
Lin Xian (zimu) starts from the prisoner of Lu Bujun, to the military advisor under Cao Cao's tent offering wine, and then to the phantom of Liu Bei's deathbed. He used an algorithm to deduce the three points of the world, but he deduced which battle he should die in the most. When Cao Tao asked him, "The tea is getting cold," he said, "Just right." This was the only warmth in troubled times, and it was also the farewell he wrote with his own hand. The tip of the brother's spear is always three steps away, which is just enough distance for him to block the arrow.
