Transmigrating to Rebuild the Han Dynasty

The protagonist accidentally transmigrates to the Eastern Han dynasty during Emperor Ling's reign, when the Han empire is at its most decadent. He takes on the responsibility of restoring the Han dynasty! See how he turns the tide and brings order to the land! He subdues the barbarians! Emperor Xian of Han, Liu Xie, weeps as he says, “Without Grand Preceptor Xia, our Han dynasty would be no more!” Liu Bei says, “Alas! If Xia Changqing had never been born, how could I have justified taking up arms?” Cao Cao says, “People call me a capable minister in times of peace, but compared to Xia Changqing, I fall short!” Before his death, Sun Ce weeps and says, “Little brother Quan! Let's surrender. I'm done playing! Once I'm gone, you won't stand a chance against him!”
