Military engineer Li Yue is reborn in Shu Han, just as Liu Shan summons Zhuge Liang back to court with an imperial order. In desperation, he plays the “Chu Shi Biao” aloud on his phone, and the “voice of the late emperor” shakes the entire army. Faced with Zhuge Liang's scrutiny, he is forced to invent a tale of a dream visitation from the late emperor, then repeatedly offers ingenious strategies thanks to his modern way of thinking. When supplies on the Baoxie Road are burned, history's crisis returns. With only a phone whose battery is nearly dead, can he help Zhuge Liang defy fate amid the hidden currents? This is a clash between modern thinking and wisdom from ages past, a life-and-death struggle in which an insignificant man upends history.
It has a very engaging storyline; I recommend reading it.
