Douluo: I Am the Martial Spirit Killing Immortal Sword Formation

After traveling through Douluo and becoming the grandson of Sword Douluo Chen Xin, Chen Xuan felt that this situation was stable - with a thigh to hug him and a sect to protect him, life was simply not too comfortable. Until the day when his martial soul awakened, he awakened a Killing Immortal Sword Formation... Grandpa Chen Xin: "Grandson, practice sword practice with me!" Chen Xuan: "Grandpa, I'm afraid that one sword will break your Seven Kills Sword." Sect leader Ning Fengzhi: "My dear Chen Xuan, the sect's resources are at your disposal!" Chen Xuan: "Sect Master, it seems that Douluo Continent does not have the materials that my sword formation lacks..." Tang San: "Brother Chen, let's have a discussion?" Chen Xuan: "Don't, I'm afraid I'll kill you accidentally." Looking at the trembling Pope beside him, Chen Xuan fell into deep thought: It's too strong, it's really not my fault!
