Transmigrated into a world of sword and magic, where humanity clings to survival at the bottom of the ladder — the elves are proud, the dwarves are master smiths, the sorceresses are secretive, the orcs are savage, and the centaurs roam as nomads. A hundred races war without end, and the strong devour the weak. At his lowest, Zhuang Hua awakens the Lord System: every single day, he summons one heavily-armored knight. Iron plate like mountains, lances that break spellcraft — his iron cavalry rolls over all magic and every foreign race. Orcs invade? The cavalry flattens their tribes. Elves provoke him? His heavy horse tramples their forests to splinters. Sorceresses scheme? Heavy armor grinds their dark arts to dust. Dwarves refuse to yield? An army at their gates brings them to heel. His endless cavalry multiplies by the day, a torrent of steel sweeping across the continent. From one barren fief to dominion over the myriad races of every heaven — mortals look up in awe, and even the gods grow wary. With nothing but a mortal's body, he forges himself into the greatest iron-blooded lord of all time.
