It begins with the fall of Weihai in 1938. Taoist priest Bi Yun was severely beaten for refusing to bow to the Japanese army, and his Taoist temple was destroyed. He buried his master's memorial tablet, stepped into the world of mortals with a dagger, and repaid blood with blood. On the way to revenge, he witnessed injustice and was finally rescued by the Communist anti-Japanese troops. Here, he understood the true meaning of "the great road" - not for his own benefit, but for the benefit of all the people in the world. He burned his Taoist robes, used what he had learned throughout his life to save the country, and completed the reshaping of his faith from "cultivating Taoism for himself" to "joining the world for the people." In the winter of 1942, in order to cover the evacuation of the masses, he spilled his blood under the ancient pine hillock and lived up to the principle of "benefit without harm" with his life.
