Second Time Travel: from the Emperor of Another World to the Human Emperor of the Immortal World

Qin Dingtian accidentally traveled to an imaginary world and became the king of a small country in troubled times. He used modern people's IQ and system to unify the world, and traveled all over the world with his iron cavalry. But when the Qian Dynasty was at its peak, he and his elite troops traveled to the world of immortality. Qin Dingtian started An Tianxia again. … Qin Dingtian, the ancestor of the Great Qian Dynasty, swept through the troubled times with his modern soul, conquered the five dynasties with his iron cavalry, and finally became the ninth emperor of all nations. At the celebration banquet, a golden light drew him and the most elite Qianwu army into the world of immortal cultivation - here the immortals wielding swords and flying in the sky regard mortals as ants, move mountains and fill seas at every turn, and regard the rise and fall of dynasties as fleeting clouds. Qin Dingtian raised his sword and stood up: My torrent of steel will crush you immortals! The Qianwu troops who only obeyed the emperor's orders came out in formation, their black armor reflected the sun, and the cold light of their swords pierced their bones. Immortals entered the battle, and their cultivation level plummeted! It can also sacrifice the cultivation of the entire army and make the gods and demons become mortals! When gunpowder collides with spiritual energy, when military formations challenge immortal magic, when emperors from other worlds sit high on dragon thrones, looking down at hundreds of kneeling immortal families—— "I have said that wherever the sun and moon shine, and wherever rivers reach, it is all dry soil!" Let's see how the emperor from another world can create an immortal dynasty in this land of immortality!
