Armor Summoner Ping Yang transmigrates to Teyvat, arriving in Mondstadt with a Summoner Device. The Flame Dragon Armor makes its debut and shakes Mondstadt to its core. He becomes a Knight of the East Wind, fights alongside Eula, and travels far to Snow-Tombed City to unlock a new set of armor. But the power of the armor harbors a corrupting influence: the greater the power, the higher the price. A theft at the church sends him chasing clues all the way to the Salt of the Earth, where he encounters a mysterious man in a long robe investigating ancient ruins. The old history of the gods slowly comes to light, and the thousand-year secrets of the Salt Kingdom await the Armor Summoner's discovery. Armor is the blade, and the knight is the heart. When the roar of armor echoes across the Seven Nations, no one will be able to stand alone.
