In the fifth year of Jian'an, the modern historian Chen Shou accidentally traveled back to the Zhongping reign of Emperor Ling of the Han Dynasty while compiling the historical materials of Soochow, and became Sun Jian, the fierce tiger from Jiangdong. When the familiar history books turned into battlefields of blood and flesh, and when the familiar battles between princes turned into intrigues and intrigues, he had no choice but to re-take the path of rise full of blood and fire as Sun Jian. Without the golden finger and the blessing of the system, he could only rely on his understanding of the situation in the late Han Dynasty to re-examine the civil servants and generals around him - those figures that rushed past in the history books were the Ming Dynasty masters who had just emerged in Zhou Yu's eyes, the majestic but unfamiliar father in Sun Ce's memory, and the founder of Jiangdong that Sun Quan had not yet understood. From pacifying Shanyue to conquering Dong Alliance, from dealing with Yuan Shu to managing Jingyang, he corrected the deviations of history step by step. However, in the vortex of the missing seal and the breakdown of alliances, he gradually understood that the so-called "mandate of destiny" was just the condensation of mortal blood and sweat. When arrow wounds and old illnesses eroded his body, he stood on the bank of the Yangtze River and looked back for half his life. He finally understood that what he really wanted to leave behind was not the cold historical records, but the Jiangdong foundation that allowed the Sun family to gain a foothold in troubled times. This is the story of an ordinary person becoming "Sun Jian", and it is also a passionate legend that rewrites the rise of Jiangdong.
