A Sword Asking for Directions

The technological apocalypse war accidentally traveled to the Three Kingdoms. An ordinary person from the future thought that he had traveled through time. After genetic modification, he became the best in the world. He dreamed of fighting Lu Bu and the Five Tigers. However, he found out that in the Three Kingdoms of this world, there are Xuan Gang warriors, immortal cultivators, and even real immortals. However, there is a strict boundary between cultivation and the immortal world. When the cultivation level reaches a certain level, he will encounter a thunderstorm and either die or be promoted. The protagonist takes a history book to look at the progress of the Three Kingdoms, only to find that although the Three Kingdoms followed the process, they seemed to follow different routes. For example, Ding Yuan's daughter was named Ding Yunchu, but because she did not want to enter the palace and went to the nude swimming pool of Emperor Ling of the Han Dynasty, she found someone to take her place, so she chose Wang Yun, who was also in Jinyang, as her adopted daughter. Only then did she gain legal status. However, she did not like Lu Bu, but liked the protagonist. So how will the history of Lu Bu and Diao Chan progress? Another protagonist met Zhao Yun at the beginning and became brothers with Zhao Yun through a series of deceptions and abductions. However, the wings of butterflies cannot flap the course of history. How could Zhao Yun leave the protagonist to find Liu Bei... Protagonist
