Returning the Sword from the Mountain, I Am Really Not a Swordsman

[Xianxia + Systemless + Kendo + Decisive Killing] Chen Yang accidentally traveled to the world of immortals and became a disciple of Fuchen Taoist Temple. As a mortal, he has a pure heart. Although he cannot practice cultivation, he can distinguish good from evil and hypocrisy. When he was fifteen years old, the master was dying due to an accident. Before his death, his master told him that demons and monsters love to eat the heart of an innocent child. After his death, he went down the mountain to return the sword of Luoxia Sword Immortal and seek refuge along the way. When the master drove Hexi to the west, the "bulging ghost" was rampant at the foot of the mountain. As a mortal, Chen Yang was not afraid and resolutely decided to go down the mountain with his sword. Kill the ghost, return the sword... That was the first time he held a sword, and he discovered that he could actually borrow the realm of a monk from the sword. That day, a crack opened in the sky and a gully formed on the earth. When demons feed on people, gods and Buddhas scrape the fat and suck the marrow. I have a pure heart and can kill immortals! (Ps: This book is also known as "The Red Heart Sword Master" and "The Story of Mortals Killing Immortals")
