Soul Land: I Came from Demon Slayer!

[Douluo I Fanfiction, Multiple Heroines, No System, Genius Protagonist, Swordsmanship Progression]

Lin Yang transmigrated into the world of Demon Slayer and joined the Demon Slayer Corps. With his companions' help, he dragged Muzan out to bask in the sunlight, earning a "perfect" achievement-only to transmigrate again, this time into the Douluo World, beginning his third life.

At six years old, he awakens Twin Martial Souls.

With a Nichirin Blade in one hand and demon blood cradled in the other, does that mean I'm both the Sun Hashira and the Demon King?

Stack enhancement Soul Rings on the Nichirin Blade, and every basic attack becomes an ultimate move!

His demon blood Martial Soul keeps growing with his Soul Power Level, generating its own Soul Rings and awakening powerful Blood Demon Arts!

Then there are Breathing Styles, the Transparent World... all ready to give the Soul Masters of the Douluo Continent just a few hundred million tiny shocks.

With swordsmanship, he will cut down every fiend and monster. With the Demon King's blood, he will step into the realm of the gods.
