Douluo: What a Useless Martial Spirit, That's a Zanpakutō!

(Douluo × Death!) When Xia Tian traveled through the world of Douluo, he thought that Wuhun was just an ordinary iron sword, but that night the system told him that as long as he buried enough souls, he could unlock various Zanpakutō? Tiansuo Zhanyue, Dahonglian Hyōrinwan, Heavenly Punishment King... Can these be unlocked? ! From then on, Xia Tian embarked on an alternative "death" path in Douluo Continent. "This ten-thousand-year-old Man-Faced Demon Spider, I see that your life is rough, so I might as well send you to the Soul Society to live out your days." "Senior Contra, I see that you have done many evil things and killed countless beasts in your life. Why don't you go to Soul Society to reform?" Don't rely on soul rings, rely on soul burial! Use swastika instead of soul skills! Faced with the blue and silver entanglement that was coming, Xia Tian smiled slightly and said, "Go with my Blade Ruohuo!"
