In a parallel world, Li Zicheng has breached the capital. The Ming dynasty stands at its darkest hour. The Chongzhen Emperor, Zhu Youjian, clutches a white silk sash and stands beneath the crooked old tree on Coal Hill, despair in his eyes. “Your Majesty, I will accompany you on your final journey!” the old eunuch sobs. Just then, Zhu Youjian, who has transmigrated here, tosses the sash aside, his gaze icy. “My final journey? The Ming dynasty still stands. It’s these traitorous rebels who should meet their end!” [Ding! The Eternal Emperor sign-in System has activated!] [First-day sign-in successful. Reward: Marquis Champion Huo Qubing + 800 Han Imperial Guards cavalrymen!] That night, the gates of Beijing opened wide. Watching the crimson lightning tear through the darkness, Li Zicheng shrieked in terror, “Where did the Ming get Han dynasty cavalry?!” Huo Qubing sits astride his horse, saber in hand. Behind him, eight hundred iron riders are as fierce as wolves and tigers. “The Cavalry General is here! Who dares harm our emperor?” … From that day on, history went completely off the rails! “The Son of Heaven guards the gates of the realm, and the sovereign dies with his country!” Sign in for [Bai Qi, the God of Slaughter] and bury a hundred thousand enemies alive, striking such terror into the enemy that they flee at the mere mention of his name! Sign in for [Han Xin, the Immortal of War] and annihilate the rebels with an ambush on all sides, leaving Zhang Xianzhong begging for mercy! Sign in for [Zheng He's fleet] and sweep across the seven seas with steam-powered ironclads. The sun never sets on the Ming Empire! Zhu Youjian: I won’t just keep the Ming from falling. I’ll plant this dragon banner in every corner of the world! [The blurb can't do it justice. Come in and see for yourself.]
