A history student is unexpectedly reborn as Kaiser Wilhelm II in 1915, during the raging flames of World War I. He decisively halts the deadly submarine war, champions the technological revolution of tanks and aircraft, strategically sows discord among the Allies, and secretly funds the spark of the Russian Revolution. From breakthroughs on the Eastern Front to the formidable Western Front, from court intrigue to diplomatic backroom deals, he leads Germany to defy historical destiny, triumph over the war, and forge a Central European alliance centered on Berlin. This is a clash of modern thinking and imperial ironclad force, witnessing the "disabled hand" reshaping the world.

The soul travels back to the Middle Ages as a Florentine citizen. Starts in Belgium and is forced to join the war.

The Hundred Years' War between England and France, the Black Death, church division, and total war in Europe.

In this endless world of chaos where swords, blood, iron and fire are intertwined, he bravely moves forward.

The iris and lily, symbols of France, blossomed again under his command, and England, with the broom rose as its emblem, was also impressed.

He is driven not by the name of the Father nor by the glory of anyone else.

Only the belief in my heart:

"I will fight to the end, until this chaos ends."

1. When Lin Yan, a science and engineering student, opened his eyes, he found himself as Chamberlain at 10 Downing Street in 1939—a declaration of war against Germany lay on the table, and outside the window, the countdown to the collapse of British hegemony was underway. But clutching his Zippo (his only token of the future), he was determined to overturn the script and personally rebuild British glory at 10 Downing Street.

Travel back in time to 19th-century Greece and witness his rise from a small Balkan nation. Lead Greece to its great ideals, restore the glory of Rome, and make the name of "Rome" known from Ireland to Khitan! And this is Constantine, the only sun of the Balkan Peninsula, the heir of Komnenos, the second Aristotle, the world's restorer, the Turkic butcher, and the loving father of the Roman people: Rome has only one chance to be revived. If you don't seize it, then let me do it!

Tsar Peter the Great of Russia, Augustus the Strong of Saxony, King Christian of Denmark, Frederick I, the "Soldier King" of Brandenburg... Across the European continent, countless enemies aimed to crush the hegemony of the Swedish Empire. In the face of powerful adversaries, the Swedish King Karl XII—who hails from a future era—tells his soldiers: "Victory or death."
