The timeline is locked in the sixth year of Zhongping (AD 189). Emperor Ling of the Han Dynasty had just died, He Jin was killed, Dong Zhuo had not yet entered the capital, Luoyang was in chaos, the eve of the separatist rule, and the starting point of the collapse of the world.
Chen Feng, 28 years old, is the retired commander of the special forces reconnaissance company in the Eastern Theater Command. He has served for 8 years. He is proficient in combat, tactical command, field survival, basic military industry, medical first aid, and small arms principles. He is a serious fan of "Romance of the Three Kingdoms" and "Book of the Later Han Dynasty". He knows the geography, people, troops, systems, grain, and ordnance of the late Han Dynasty. He has a calm and decisive personality, iron-blooded discipline, honors promises and trustworthiness, is not pedantic, and does not kill indiscriminately. He reshapes the army of the late Han Dynasty with modern military thinking.
Late at night, an old Three Kingdoms arcade machine was modified and electrocuted by high-voltage electricity. The soul traveled into the body of a refugee boy in the late Han Dynasty. The physical body was 16 years old and the body was strong, retaining all modern memories and special forces skills.
