In Ghost of China, in the main story quest "The Ghost of Beijing", after defeating General Temuge you will slice off his right arm while he's trying to flee and then you will sever his torso, all with 2 very fast and brutal cuts. After that you will be prompted to press L3 + R3 in order to unlock the Dragon's Stance, in this stance you'll be able to strike fear into the mongol's eyes and kill 7 mongols with one strike each, all while the protagonist screams "For Beijing! Grab any weapon you can find and destroy the mongols, citizens of Beijing!" and "Do it for China!", motivating the citizens to fight back the mongols alongside you.
