Great Qin: Starting Out with One City and a Million Iron Cavalry to Conquer the World

[Alternate-history Qin Dynasty + troop-raising System + conquest + decisive and ruthless + building an imperial dynasty]

His soul transmigrates into the Qin Dynasty, where he becomes Ying Lan, the Ninth Prince, who is about to be sentenced to death. Fortunately, his god-tier troop-raising System awakens just in time!

From the start, he gets a solitary city, and can even summon invincible troops from the Myriad Worlds!

“Ding! Congratulations, Host, you have summoned three thousand Snow Dragon Cavalry!”

“Ding! Congratulations, Host, you have summoned ten thousand Black Armor Troops!”

“Ding! Congratulations, Host, you have summoned one hundred thousand Tiger-and-Leopard Cavalry!”

When the remnants of the Six Kingdoms provoke him, Ying Lan waves his hand, and a million iron riders sweep everything away!

The Xiongnu are invading? Sorry, my Roman Legion has been waiting for them!

Faced with the First Emperor's suspicions, Ying Lan simply unfurls a world map. “Imperial Father, this world is far larger than you imagine!”

Starting from a remote border town, he overthrows the old order, develops agriculture and commerce, and builds an unparalleled imperial dynasty!

When Ying Lan stands at the peak of the world, wherever the sun and moon shine, wherever rivers flow, all is Qin territory!
