Gou Jian, brilliant, gloomy, decisive and resourceful. With the spirit of "living together for ten years, learning from the scriptures for ten years", he turned a weak country, which was denounced as "the water is turbid and gurgling, so people are stupid and dirty", into a big country with rich Qiang Bing. During the Spring and Autumn Period, this monarch who once tasted the courage of others and lost the State of Wu became a tyrant, had a hard life, which was shocking enough to make people cry and shake their hearts!

Gou Jian has been abroad for ten years. First, he escaped from the State of Wu, crossed the Dabie Mountains to reach the capital of Chu, and then went deep into the hinterland of the Central Plains to travel around the world. The only one who accompanied him was Sun Tzu's Art of War, which said, "If you defeat the enemy without fighting, the good is good." In today's era of feud between princes, are there any soldiers who can defeat others without fighting? He tried to find it. Now that the old country is in sight, he is filled with emotion and goes straight to the secret passage of high city.

In March (497 BC), the spring rain in the south of the Yangtze River continued. In this rainy season, it's annoying enough. Unexpectedly, the news that Yue Wangyun died of illness came from the palace, and then the new Yue King Gou Jian succeeded to the throne. Unexpectedly, on the sad day of the whole country, there came another surprising news: He Lv, the king of Wu, assembled domestic land and sea forces and invaded on a large scale, and now he is rushing to China with lightning speed!
