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..."

Natural markings + natural transparency + complete sun breathing = Muzan's new father

(Not a time travel story, the protagonist does not know the plot)

Chiba Yang, whose everything was taken away by the demons, joined the Demon Slayer Corps at the invitation of the Flame Pillar and became the stepson of the Flame Pillar. From then on, all the demons ushered in their nightmare.

The protagonist is a descendant of the Jigoku clan. He looks very similar to Yoriichi. He comprehended the Breathing of the Sun on his own and created his own sword skills.
