The Strongest Summoning System of the Three Kingdoms

Yuan Hong, the concubine who traveled through time and became Yuan Shao, has a low status and no fame. He is looked down upon and excluded by his legitimate sons inside, and surrounded by princes outside like wolves. His future is bleak. So what, I have a system in place that can summon the heroes of the past to my advantage. You, Lu Bu, are unparalleled in the world, and I, Li Yuanba, the God of Thunder, am invincible. You, Zhuge Liang, are as wise as a demon, but I, Liu Bowen, am as good as a god in predicting things. Look at me, a humble concubine, rise to prominence, lead all generations of heroes, sweep across the Three Kingdoms, unify the world, and achieve imperial hegemony!
