In the third year of Jianyan, the Jin soldiers went south, and the Song Dynasty was in turmoil. A fragment of the "Book of All Realms" that has been lost for three hundred years suddenly appeared in Tokyo. It records the secret method of connecting all heavens and all realms. It is said that those who obtain this book can understand the past and present and reverse the world.
Qin Guanlan, a young university student, was involved in a shocking conspiracy that spanned a thousand years due to an accident. He was horrified to discover that the Jin Bing invasion was not just a foreign invasion. Behind it was a huge conspiracy that could overturn the foundation of the entire Chinese civilization - someone was trying to replace "Tao" with "fire" and tamper with the way of heaven with strange magic, so that the Central Plains would never be restored.
In times of crisis, Qin Guanlan obtained a mysterious ancient book - "Tian Yuan Lu". This book may seem ordinary, but in fact it is a living history book that records the most original "Tao of Investigating Things" of Chinese civilization. It told him: the real power does not lie in magical powers, but in this land, this group of people, and this glorious five-thousand-year-old civilization itself.
From Tokyo to Lin'an, from rivers and lakes to temples, Qin Guanlan will join forces with loyal men such as Yue Fei and Han Shizhong to fight side by side with the most mysterious organization in the Song Dynasty, "Jiguge", to find the road to light in blood and fire.
This is a duel between civilization and barbarism, a battle between "Tao" and "Fire". What he wants to protect is not only this turbulent dynasty, but also the last fire of Chinese civilization.
