Anime Crossover: With the Millennium Puzzle, I Play the Sea God from the Start

I transmigrated to an island nation in the Taisho era and became Aocheng Ye.

I never expected to bring along the Millennium Puzzle game System from before I transmigrated.

At first, I only agreed to take on the System's challenges and training because I had obtained the Time Magician, who could travel through time back to the twenty-first century.

But the monsters that materialized weren't for card battles. They were meant for real combat?

Win, and you get the corresponding card. Lose, and you die?

I had planned to pick on some weak monster cards to grind experience and grow stronger.

But I never expected that this Taisho-era setting wasn't historical at all. It was the world of Demon Slayer! I ran straight into Upper Rank One, Kokushibo.

After losing the battle, I was injected with Muzan Kibutsuji's blood and nearly turned into a demon. I had to use another spirit as my body instead.

Looking at my new body, then at the activation quest before me, Aocheng Ye felt conflicted.

"To activate the Sea God's Priestess, you need to earn the faith of a hundred people in the Sea God."

"Fail to meet the goal within a month, and the fusion will fail."
