When Cao Yun was operating in the South China Sea with a salvage ship, he discovered the ruins of a shipwreck from the Tang Dynasty. While salvaging a hosta embedded with special patterns, he was accidentally pricked on his finger, and his blood activated the remnant soul of a female general from the Tang Dynasty hidden in the hosta, triggering a time and space vortex. Cao Yun's soul traveled to the "Great Xia" dynasty similar to the Tang Dynasty, and became an 8-year-old boy. He shouldered the grand ambition of rectifying his father's name, saving the people from war, and creating a peaceful and prosperous age.
