Three Kingdoms: Cao Cao Has a Selection System

"Defeated! Cao Cao, who had attacked Dong Zhuo, returned to Chenliu in disgrace. He had no more than 10,000 troops and could not defeat Cao Ren. But no one expected that this Cao Cao had a thousand-year history of future generations in his mind, and was even bound to the 'Cause and Effect Selection System'! Puyang City is in crisis, the system pops up: [Option 1: Face Lu Bu head-on - the immediate probability of death is 70%; Option 2: Abandon the city and retreat - lose Yanzhou in the short term, and struggle to fight for the Central Plains in the long term; Option 3: Lure the enemy into burning food - Lu Bu's morale is reduced by 30% in real time, increase the number of troops by 10,000 in the short term, and Lu Bu has no chance to turn around in the long term] He curled his lips and smiled, choose three! When the fire started, Lu Bu's Fangtian Painted Halberd had not yet been swung, and the food and grass had turned into ashes. Guandu, Chibi, Hanzhong... At every key node, the system spread out the 'optimal solution' in front of him. When Yuan Shao was still struggling with food and grass, his light cavalry had already attacked Wuchao at night; while Zhou Yu was still preparing for a fire attack, his warships had already been dismantled. In this life, Cao Cao is no longer 'a capable minister in times of trouble, a traitor in troubled times' - what he wants to do is to be the Emperor of the Wei Dynasty who conquered the Nine Provinces!
