During the Jiajing period, the "Zhendong Escort Agency" on the official road in Beidi was just a small shop with three shops. Chief escort chief Shen Xiaoshan, with his "iron sand palm" and "faithfulness" skills, led five escort divisions and three old escort cars, specializing in short-distance escorts from Baoding to Tongzhou. At that time, the escort flag was a piece of washed white coarse cloth with the word "Zhendong" crookedly embroidered on it. However, when escorting disaster relief grain was robbed, Shen Xiaoshan had to bear it at the cost of three broken ribs.
In the past ten years, the escort flags of the Zhendong Escort Bureau were replaced by scarlet satin, and the number of escorts expanded to more than thirty, capable of traveling thousands of miles from Mobei to Jiangnan. Shen Xiaoshan's only son, Shen Qingya, has learned the family palm skills and is also resourceful. He has overcome the "Ecstasy Formation" in Heifeng Ridge, fought the "Water Dragon Sword" of the Yangtze River water bandits, and even dared to accept the birthday escort of the prince of Beijing. When the escort flag arrives, the Green Forest people will shout "Master Shen's righteousness" when they see it, and the government will also give him three points. But everyone knows that behind the safety of every escort trip are the scars hidden under the clothes of the escorts, the incense burned by Shen Xiaoshan in front of the Buddha all night, and the "pension" that can never be filled in the ledger.
However, there is no such thing as a feast that lasts forever. When the lead bullets of Western muskets penetrated the chests of the most courageous bodyguards, when the telegraph lines were spread along the official roads, and when the merchants preferred to pay customs duties and use the official post offices rather than take the "risks of the world," the flags of the Zhendong Bodyguard Bureau began to gather dust. Shen Qingya wanted to turn the tide. He tried to train new soldiers and learn arithmetic.
