In the world of Blue Star, ferocious beasts are raging. Everyone can awaken their superpowers and have the opportunity to become a strong and powerful person!

However, Xu Jingming who traveled through time only had E-level powers.

Fortunately, the Deep Blue System appeared, and the E-level weak electricity ability was upgraded to the S-level Purple Sky Divine Thunder!

Not only that, every time he kills a ferocious beast, he can gain ability points.

Consume power points to upgrade your level and strengthen your skills.

"Dark Blue, give me some more!"

Pability points -1000, level up! Second level superpower!

Pability points -1,000,000, Zixiao Divine Thunder evolves! SSS level Chaos God Thunder!

…

Thus, a legend belonging to Xu Jingming was left on Blue Star.

Tianjiao: "In front of him, I don't deserve to be called Tianjiao at all."

Tutor: "From artistic conception to domain to law, the speed at which his abilities advance is terrifying!"

Goddess: "So what if I'm cold and aloof, and I'm in love with the country? In the end, I have to kneel down..."

Luochuan woke up and came to the world of Demon Slayer.

Together with Zenitsu, he was picked up and raised by the Pillar Jigoro Kuwashima.

However, he did not have the talent to practice breathing techniques, so he could only learn Thunder Breathing from Zenitsu.

Just when Luochuan was thinking about how to survive in this world full of ghosts, Luochuan awakened the friend system!

As long as you become friends with the other party, even if it's just verbal, you can get various rewards!

Add Zenitsu as a friend and receive the reward of Lightning Breathing Type 1: Thunderbolt Flash!

Add Tanjiro Kamado as a friend and receive the reward "Thread of Gap"!

Add Lei of the Lower Five as a friend to receive a bonus Blood Demon Art line rotation!

Add the Flame Pillar as a friend and receive the reward of the Secret of Breathing of Flame: Type Nine: Purgatory!

"No, you are full of blood demon arts, you say you are a Hashira??"
