In the first year of Xuanhe, in the Juyi Hall of Liangshan, when Song Jiang held up the imperial wine for recruiting people with great expectation, the modern military strategy doctor who traveled through time and transformed into the "green-faced beast" Yang Zhi overturned the wine table in public, angrily denounced that this so-called "loyalty" was just taking his brothers to serve as cannon fodder for the corrupt imperial court. Knowing that the "Shame of Jingkang" was coming three years later and that the Jin soldiers and cavalry would crush the backbone of the Central Plains, Yang Zhi resolutely led more than 20 fierce generals including Lin Chong, Wu Song, and Lu Zhishen to fight out of Liangshan, occupy Erlong Mountain, and activate the [War Lord System]! From then on, he was no longer a lost dog, but an iron-blooded warlord who started the industrial revolution and held the range of truth in his hand. When the imperial court was decaying in the midst of singing and dancing, iron-making blast furnaces had been erected in his Erlong Mountain, and cement fortresses had risen from the ground; when the Jin Kingdom Iron Pagoda thought it was invincible and went south, they were greeted by the roar of the Shenji Battalion's volleys of guns and red-coated cannons. In this life, Yang Zhi refused to live on his knees and vowed to die standing up. Taking the banner of "clearing the emperor and resisting foreign aggression" as his banner, he declared to the world: I will defend the country that Zhao Guan's family cannot defend, and I will save the people who cannot be saved by the imperial court!
