Late Qin: I Take the Hegemon as My Big Brother, and the Yu Family Heiress Joins Me

After staying up all night watching videos, I wake up in the chaotic final days of the Qin dynasty! From the start, I escape death and become sworn brothers with the Hegemon-King Xiang Yu, clinging to a powerful ally! Armed with advanced military technology from the future: I upgrade repeating crossbows, unleash explosive gunpowder, and launch flying rockets, sweeping aside every enemy! I meet the daughter of the Yu family, and we stand together through the chaos, sharing a deep love without tragedy! I see through Liu Bang’s schemes, stand up to Zhao Gao’s plots, and thrash the invading Xiongnu! With a technologically advanced army, I defy fate and help the Hegemon-King avoid taking his own life at the Wu River! I pacify the realm, secure the land, and protect my loved ones and the peace of the people!
