This Sword Correction Is Transforming into a Sword

Chen Ping was born in a family of immortal cultivators, and accidentally obtained an "iron sword" in the family sword tomb and recognized it as its owner. There are two mysterious skills hidden in the sword, one of which is so weird that it can make people "turn their fingers into swords", "turn their arms into swords", "turn their soul into swords", and "turn their bodies into swords". Chen Ping knew that his qualifications were mediocre, so he finally chose to practice this mysterious technique, "Sword Embryo Qi Sea", "Sword Embryo Spirit Platform", "Sword Finger", "Sword Heart"... Since then, Chen Ping has gone further and further step by step on an unconventional path of cultivating immortality.
