Li Yuanba, a modern veteran travel companion, fell off a cliff and died during a hiking rescue. When he woke up, he found that his soul had traveled through the Zhenguan period of the Tang Dynasty for three years and became Li Yuanba, the king of Zhao in the West who should have died from a thunderstorm. He inherited the unparalleled martial arts from his original body, but he just wanted to carry potatoes, sweet potatoes, corn and dried chili peppers in his hiking bag, and be a leisurely landlord at the foot of Zhongnan Mountain, build a house, buy land, marry a wife and settle down.
But Li Shimin just found him back. As a result, a modern soul who just wanted to lie down was forced to return to the court as the God of War of the Tang Dynasty: he was able to reconcile the rift between Li Yuan and Li Shimin's father and son, stabilize Li Chengqian's throne, and team up with Sun Simiao to save Empress Changsun, Qin Qiong and other important ministers; he was able to promote it at the lower level. High-yielding crops, improved farm tools, and farming methods suddenly filled up the Tang Dynasty's granary and people's hearts; Wai Ke swept away powerful enemies on the frontiers and suppressed the chaos, making everyone who wanted to take advantage of the chaos to take advantage of the Tang Dynasty understood that the Tang Dynasty would not be in chaos until Li Yuanba died.
He originally wanted to protect his small life of one village and one hospital, but in the end he had to protect the entire Zhenguan world. When family members, undercurrents in the court, and powerful enemies from the frontier approach one after another, the person who least wants to be a hero will eventually become the most irreplaceable patron saint of the Tang Dynasty. And after the world is at peace, can he return to the small village he originally longed for?
