The plan is to write three sections. First, the Austro-Hungarian Empire: how did an empire with a first-rate geographical location, advanced industry, and profound culture, seemingly with extremely high potential, reach its peak, and where did that peak lie? Second, how did the Russian Empire reach its zenith? Third, the Ottoman Empire or Italy (not yet decided). Join the book's group (878578959) for discussion.

In 1422 AD, the Eastern Roman Empire had long lost the glory of Justinian's era. Its territory consisted only of Constantinople and a few isolated enclaves such as Morea, resembling a giant ship sailing on a sea of ​​time, its hull riddled with holes, struggling to stay afloat amidst the turbulent waves of history. In this turbulent moment, a stranger's soul drifted to this land, vowing to change everything and give this ancient empire, now in decline, a new lease on life.

[Slow pace] [Build an empire alongside the protagonist]

Traveling back to 1887, one becomes Crown Prince Wilhelm II of the German Empire. At this time, Wilhelm I is old and frail, the 100-day emperor hangs by a thread, and the Bismarckian system is on the verge of collapse. Facing the impending trap of world war, a new soul takes over the steering wheel of the empire.

By 1204, the Byzantine Empire had crumbled, and its sole heirs, Nicaea, Epirus, and Trebizond, were still embroiled in infighting, completely forgetting their past grievances. In Constantinople, the Latin tyrant proclaimed himself emperor of the Romans, while in the north, the Bulgars were rampaging, greedily devouring the empire's legacy, and the Turks were also stirring, eager to gnaw at its flesh. Meanwhile, in the far east, a latent force, the Mongols, was quietly rising. The empire's collapse seemed utterly irreversible, but how would Justinian reverse the tide and raise the banner of revival once more?

He was reborn as a German company commander, but led his troops in a mutiny an hour before the armistice.

He changed his mind about the assassination attempt, saving the revolutionary heroine, Rosa, from peril.

He founded the "Red Front," becoming the Nazis' most feared enemy.

"I'm not here to join history, I'm here to rewrite it."

In 1918, desperate Germany wept. A spirit from the future brought it the only answer.

This is an unimaginable path, an epic tale of ideals and iron will.

The path has been shown.

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.

The double-headed eagle watched over his empire, gazing both at its former glory and the abyss of reality. In 1185, Constantinople fell to rebellion and betrayal, and the Komnen family's eagle standard fell sadly amidst blood and fire. In 1192, Tiberius on the banks of the Cura River welcomed two extraordinary guests. Alexius Komnen, a name born to bear the destiny of an empire, was forced to make his judgment before the end times. Would he follow in the footsteps of the old gods into destruction, or would he build a new order upon the ruins? His choice would determine the ultimate answer to Roman civilization. ——————Book Club: 809500903 (Welcome to join and discuss)

Intense pain forced me to open my eyes. After getting familiar with my surroundings, I realized I'd been transported to the body of a middle-aged German man. Damn, my mind wasn't listening, and I couldn't remember my own name. Apparently, I'd lost my memory. Fortunately, I knew I was Chinese. How did I know I was Chinese? Because my brain automatically converts the German I hear and see into Chinese. It also automatically converts the language I want to speak into German. The yellowed calendar marked the year: October 4, 1938. It seemed I had a new identity: Erich von Richthofen.
