So I love playing Sun Jian in 190. It's my favorite campaign and Character. However, every time I reach the Duchy Rank I always end up with Cao Cao vassalizing Lui Bei.
Cao Cao is the Duchy of Wei, which I know I know you're supposed to take out Cao Cao immediately.
That being said I can't get Lui Bei to want to become independent. It's a 87 diplomacy cost and the only way he will accept is for massive amounts of money and territory. The primary driver is because he actually likes Cao Cao.
Is there a way I can get Lui Bei to not like Cao Cao so I can support his independence?
