The ninth prince Lin Fan was publicly humiliated by the second prince Li Xuan at a palace banquet and was sent to guard the abandoned royal library "Chen Pavilion". In desperation, he accidentally activated the [Historical Echo System]. By touching ancient books, you can gain the "battlefield deduction" ability of the soldier Sun Wu. When the war in the north became urgent, Lin Fan relied on this ability to propose a shocking plan in the court, and was appointed by the old emperor as the supervisor of the army. In the northern border, Lin Fan continued to use the system to touch the ruins of ancient battlefields and old weapons, acquire the skills of famous generals in the past, and recruit buried talents. He staged a series of military miracles in which he defeated more with less, successfully repelled the enemy, and became a god in one battle. Returning to the capital with his illustrious military exploits and the support of the army, he officially started a head-on confrontation with the second prince Li Xuan to seize the throne.
