In the early years of the Republic of China, the situation was turbulent and war was raging. Ye Fan, who was in his early 20s, was the only promising descendant of his family. Under the instructions of his elders, he embarked on a journey to find Lian Po's military strategy during the Warring States Period. This military book is not only related to the rise and fall of the family, but also contains shocking secrets that can rewrite the historical evaluation of Qin and Zhao. It may even be the earliest military book in Chinese history.
Accompanying him are his childhood sweetheart Linger, Zhao Peng, the bodyguard arranged by the family, Chen Zhong, and fellow countryman Shen Wenzhou who returned from studying abroad. At first, everyone supported each other, deciphered the codes left by the family, traveled through the war-torn areas, and evaded the pursuit of all forces. However, as the journey deepens, crises are everywhere, and the people around him encounter changes one after another: Chen Zhong dies to protect Ye Fan, and Shen Wenzhou reveals his true face. He is actually a descendant of the Shen family who has a feud with Ye Fan's family, and wants to seize the military book; Zhao Peng is shaken by greed, and although he gets lost, he is seriously injured and has the intelligence of a young child; Ling'er has no choice but to compromise with Shen Wenzhou in order to save Ye Fan.
With careful logic and tenacity, Ye Fan solved the puzzles one after another amidst many hardships, and finally found the military strategy buried in the Chongzhen Mausoleum. But victory comes at a heavy price, and there are not many trustworthy people left around him. What surprised him even more was that the broken pages in the military book pointed to deeper secrets, and a mysterious force pushed him to start a new path of exploration.
