I Still Want to Make a Heavenly Sword!

(Upgrade flow, slow to warm up, decisive killing, behind-the-scenes flow, relaxed...) My name is Zhang Xiong. Unfortunately, I was struck by lightning just now and ended up traveling through time. The good news is that I have traveled to a world where martial arts are respected. I heard that there are immortals in this world, and I may be able to realize my childhood dream - immortality and a free world. The bad news is that I traveled through time and became an orphan named Song Aniu. There is no food at home and I am about to starve to death. The good news is that my golden finger appeared - it was a ball of thunder. It seemed that it was the one that killed me and brought me to this world. Damn it, is this lucky or unlucky? This ball of thunder is the nemesis of ghosts and can evolve by swallowing them. Evolving for the first time, it has transformed my body. In the second evolution, I can seize the body of any creature I just killed. The third time... "Wait a minute, the name Song Aniu is too tacky. How can he be worthy of the protagonist of my era?" "Well, from now on, call me - Heavenly Sword Song Que! I am a swordsman."
