One Refinement Per Level: Fortune Equal to Heaven Gu from the Start

[Fortune from the Start + Original Gu Worms + Fast-Paced + High Martial Arts + No Female Lead + Satisfying Power Fantasy + Ruthless] After changing class to Bug Master, he can only control bugs that get crushed underfoot? At the critical moment, he awakens a System: [Gu worms are bugs too!] Every time Su He levels up, a Gu worm takes up residence in him, making him stronger. This should have been a System that depended entirely on luck, but it gave him a huge surprise with his very first Gu worm: Fortune Rivalling Heaven Gu: A legendary luck-path Gu worm. Its host continuously absorbs the luck of those around them and the luck of Heaven and Earth, turning it into their own and ensuring permanent good fortune. From then on, his fate underwent a dramatic transformation, as one legendary Gu worm after another revealed its power in his hands: Time Reversal Gu, Blood Dropper, Strength, Wisdom, Destiny... Immortality! On top of that, the System could also unlock a series of killer moves: Reverse Flow Body-Protecting Seal, Five-Finger Heart-Piercing Sword... Su Yuan was invincible on the path of the Bug Master. When the starry sky's gods and demons descended upon the mortal world, he said nothing, striking in an instant and refining them in the blink of an eye.
