Fushi wo Motomeru Mono, Kore wo Doushi to Yobu

In a remote village on the Shiei Continent, there was a boy named Kou. At the age of nine, he regained the memories of his previous life and came to realize he was in a world similar to Tang Dynasty China, where immortals and demons exist. And so, Kou became a servant boy to his master's son. However, he was forced to accompany him to the entrance exam for the Hollow Rite Cave , a sect that seeks divine immortality, and for some reason, ended up passing. Now, Kou will make full use of the "Instantaneous Memory Ability" he has secretly possessed since his past life, memorizing secret texts and rising through the ranks as a Taoist practitioner. Let's go! Onward to the path that leads to immortality!
