Crossing the Qin Dynasty, My Sword Can Connect the Two Worlds

"Uncle policeman, I am the king." "I'm not crazy, I'm in ancient times, and I'm traveling through time." Zheng Ying ate hot pot and sang songs. Unexpectedly, he traveled through the Warring States Period and became the leader of a country. He originally thought he would have to summon the generals with a system in his hand, and he would wave while summoning. But I didn't expect to travel to an ancient time of cultivation. People here can not only fly into the sky and escape from the earth, but some can even destroy an entire city with one person. Adhering to the expectations of hundreds of millions of netizens, he is determined to spread the flag of Daqin all over the world so that future generations will never have to learn foreign languages. Inadvertently, he learned that his sword could connect the two worlds. He contacted the organization to transmit all the chapters of ancient lost martial arts back to the modern era, and brought back the chapters of Qi training during the Warring States Period, the most popular period of cultivating immortals, to feed back to the modern era. Modern aircraft cannons and even Lingqi cannons with modern structures were transported to ancient times, and the two worlds instantly made up for their respective shortcomings. The first dimensionality reduction attack spread throughout the Six Kingdoms, and ordinary people with Lingqi Cannons could kill the top masters in the world. At this point, Lingqi cultivators spread throughout the modern era of Great Xia, and high-tech weapons filled the Warring States period. One day, Zheng Ying sat on the throne and watched the Xuan Banner of Qin spread all over the world. He smiled and said: "All fear comes from insufficient firepower." "All eyes are on me, fire!"
