Toaru Majutsu no Index - Volume 8, Chapter 2: Girls facing off. Space_and_Point.

Sagiri was born in silence, no cry, no breath, no heartbeat, until a pulse of ancient energy tore through the air and marked him as the last child of a dead people. Cold, disciplined, and frighteningly calm for his age, Sagiri has spent his life hiding a power even he doesn’t fully understand. He does not smile. He does not fear. He does not allow anyone close. Because the thing living inside him 'The Echo' never sleeps.

When he woke up, Zhou Sui became a low-level Qi refiner in the world of immortality. Fortunately, he obtained the most precious Gu god bowl, which can refine various Gu insects.

Refining the Spring and Autumn Gu can prolong life and make you immortal.

The refining golden cicada Gu can give birth to dead people, flesh and white bones.

Refining the Dragon Elephant Gu to gain the power of the Dragon Elephant, the body of the Dragon Elephant, and the indestructibility of the King Kong

But the Gu he refined for the first time was the Infatuation Gu.

From then on, he discovered a bright road to cultivation.

The years change, the mountains and rivers change, but I am the eternal Zhou family.

But the world had taken it away from him.However, he knew that—whatever was inside it, had to be powerful enough for him to stop this calamity.His final regret echoed through the silent wasteland:“If I had learned that damn book, we’d still be alive.”With his dying breath, he wished for only one thing:To go back in time and claim that forbidden power, no matter what.A single star answered.Ryn opens his eyes ten years earlier, on the day he received his first skill.WHAT TO EXPECT:- Korean Regressor Fantasy, if you like that genre this might be the one for you. Think (Trash of the Count's Family, Swordmaster's Youngest Son, FFF-Class Trash Hero)- Romance subplot is prevalent. This is not a harem novel!- MC is NOT naive, and will NOT be afraid to make morally gray choices! Readers advised!
