Traveling Across Wuhu, I Guard the Rivers and Mountains for the Han People

When a landslide occurs at the border, special forces king Lu Feng clutches a mysterious bronze token of the Huns. When he opens his eyes, he falls into the Wuhuanhua purgatory where "white bones are exposed in the wild and there are no roosters crowing for thousands of miles." He is possessed by a remnant soldier of the Western Jin Dynasty who was stabbed in the left shoulder and dying. There was no Type 92 pistol, no support from comrades, only torn clothes, a poisoned scimitar, corpses everywhere and the Huns' cavalry looking at them eagerly.​ Captain Sharp Blade, who used to frighten the enemy, has now become an ant in troubled times. However, he relies on his special skills to fight back in the mountains of corpses and seas of blood, and relies on his survival skills in the wild to survive in desperate situations. He hid in cellars, walked through wild forests, and met hunters. From being alone to gathering the remaining soldiers, from just seeking self-protection to swearing to defend the land, he used modern tactics to fight with cold weapons, and protected the homeless people with an iron-blooded heart.​ The Xiongnu trampled the Central Plains to pieces, and the Jie, Xianbei, Di, and Qiang took advantage of the chaos to wreak havoc. The Western Jin Dynasty was in decay and the people were displaced. Holding the bronze token in hand, Lu Feng explores the mystery of time travel while making steps in the troubled times - killing murderers, collecting remnants of soldiers, building strongholds, and resisting barbarian invaders, using his own efforts to ignite a glimmer of hope in the dark and troubled times.​ In the glint of the sword, there is the precision and ruthlessness of the special forces; in the ups and downs of troubled times, there is the backbone and perseverance of the Chinese people. When a modern special forces soldier encounters the cruelest troubled times in ancient times, can he use his skills to protect the people? What kind of shocking secret is hidden behind the bronze token? Guarding the land with iron blood and fighting to stop killings, let's see how Lu Feng continues to write the legend of fighting against the Huns in the desperate situation of the Five Husbands!
