Three Kingdoms: Sima Replaced Wei? I'll Take Sima's Place!

Traveling through the Three Kingdoms, Zhang Huai, a top student in the history department, became a member of Sima Yi's family. As a result, he was caught eavesdropping and somehow became one of Sima Yi's subordinates under Cao Rui. Twenty-five boys? Zhang Huai: Twenty-five boys? No, I want to hedge my bets and take them all! Sima Yi: Well done! I will marry my daughter to you! Zhang Huai: Will my daughter marry me? No! I want the people, and I also want the property of your Sima family! I don't make a choice, I want them all! Cao Rui: I will promote you, and you can help me check and balance Sima Yi! Zhang Huai: Promotion? No, your Cao family's empire will benefit the Sima family anyway, why not just benefit me! Relying on the memory of his previous life, he came up with many inventions and had the advantage of foresight, allowing Zhang Huai to be one step ahead of Sima Yi in everything. Money? I have! People? I have! The emperor takes turns, come to my house this year!
