Humans are the spirit of all living beings, Gu* are the essence of heaven and earth.

With his three views* unrighteous, a demon is reborn.

Former days are but an old dream, an identical name is made anew.

The story of a time traveler who keeps on being reborn.

A unique world that nurtures, refines, and uses Gu.

Spring Autumn Cicada, Moonlight Gu, Liquor Worm, Great Qi Golden Light Worm, Slender Black Hair Gu, Hope Gu…

And a great demon of the world that acts as his heart pleases!

A story of a villain, Fang Yuan who was reborn 500 years into the past with the Spring Autumn Cicada he painstakingly refined. With his profound wisdom, battle and life experiences, he seeks to overcome his foes with skill and wit! Ruthless and amoral, he has no need to hold back as he pursues his ultimate goals. In a world of cruelty where one cultivates using Gu – magical creatures of the world – Fang Yuan must rise up above all with his own power.

Note :

Gu are legendary venomous insects, often used in black magic practices. They can take on the form of several insects, usually snakes, crickets, worms, etc.

Three views = one’s world view, values of worth and philosophy on life.

[No heroine + no saint + invincible at the same level + egoist + decisive killing + random crazy criticism + flexible moral bottom line]

The way of heaven is to reduce the surplus and make up for the deficiency, the way of man is to reduce the deficiency and make up for the surplus; Gu Xia's way is to reduce the deficiency and surplus of others and make up for his own surplus and deficiency.

…

Gu Xia traveled through time and space and became a poor scholar. Although he had AI, he had no place to play and could only cheat in the teahouse to win money. An accident Gu Xia won a broken secret book, from then on he learned Xuan Gong, embarked on the road of cultivation, and worshipped Xuanmen. With the powerful computing power of AI, the broken book in Gu Xia's hand became a complete book, the complete book became an enhanced version, and the cultivation became a smooth road. All the secret books can be understood at a glance, and the enemy's flaws can be seen at a glance. There is no bottleneck or weakness!

Unfortunately, Gu Xia's talent is not very good. Even if AI helps him optimize the cultivation plan, the speed of cultivation is still too slow. So he looked at other people who practice martial arts.

"Everyone, Gu wants to borrow something from you! I will definitely return it in my next life!"

From then on, the stars of the magic path rose one by one.

A sentient demonic sword drifts from master to master, offering power at a price. Some wielders rise, others fall—but all leave their mark on the blade. It grows stronger with each bond, shaping and shattering destinies across a blood-soaked world. This is not a story of good or evil—only the will of the sword.
