Three Kingdoms Killed Cao Cao's Time-Traveling Strategist

[Only strategy] [No system] [No brain and caution] [100% Three Kingdoms flavor] Traveling through the Three Kingdoms, my phone only had 1% battery left. On the screen was the lunar eclipse forecast for Wuzhangyuan in 234, which was my only hope of returning home. But now, in 189 AD, he is on death row in Zhongmu County. Cao Cao was being stabbed through his bones by an iron hook, but he stared at the blue Zippo flame in my hand: "Is this the magic fire?" I grinned: "No, this is science... Boss Cao, do you want to change your fate against the will of heaven?" So, penicillin revived the festering army, and black gunpowder blew up Lu Bu's cavalry. I became Cao Cao's biggest trump card. He called me "Yinlin", but wanted to lock me in the secret room at the deepest part of Tongque Terrace forever. "Mr. Gu De, it's like you have obtained the way of heaven!" He laughed wildly and burned all the history books. "From now on, history will be written by Gu!" Until that night, I captured Guan Yu alive for him, but I saw him stroking Guan Yu's green robe and murmuring: "By the way, sir... Gu dreamed about the Wuzhangyuan you mentioned last night, and you were buried there... Right?" I traveled through thousands of years to help him dominate, but he wanted to imprison me in history forever! !
