Global Martial Arts: My Basic Attack Comes with an Execute

[Decisive and Ruthless + Spiritual Qi Revival + High Martial Arts + Talents and Stat-Based Progression + Invincible + Passionate, Dark Fiction + Patriotism + No Romance + the Myriad Worlds] This is an age of spiritual qi revival, flourishing martial arts, and a struggle for supremacy across the myriad worlds. While traveling in Europe, Su Xiao accidentally fell into a rift and was reborn, awakening his golden finger: the Slaying System! As long as he completes a slaying mission or fills the slaying meter for a particular kind of creature, this System grants him talents, skills, and all kinds of power-ups from the Myriad Worlds. [Congratulations, Host! You have awakened the SSR-ranked dark talent, Eternal Night Monarch!] (Solo Leveling) [Congratulations, Host! You have obtained the Mystic Eyes of Death Perception!] [Congratulations, Host! You have learned Unlimited Blade Works!] After awakening the Eternal Night Monarch talent, Su Xiao begins his own path to godhood, slaying his way to the top all alone! [You killed an ancient true dragon. Slaying points against ancient true dragons: +1] [Your slaying meter against ancient true dragons is full!] [Your normal attacks now have a 100% chance to instantly slay ancient true dragons. You are permanently immune to 100% of the damage dealt by ancient true dragons!] [Slaying meter against ancient true dragons has reached 100%. You have obtained Heavenly Dragon Transformation!] From that day on, a legend of a god of slaughter spread through the human world. When faced with a beast tide of tens of millions and invading foreign races, he answered with a storm of sword shadows. With a single strike, countless beasts and invaders died in an instant, leaving nothing but mountains of corpses and rivers of blood! From then on, children dared not cry at night when they heard Su Xiao's name. Across the Myriad Worlds, tales spread of an unparalleled human demon: at the least, he would wipe out an entire clan; at the worst, he would exterminate a species. In his rage, he could destroy the Myriad Worlds! (The main storyline begins after 50 chapters. One man becomes an army and slaughters all living things in a fit of rage!)
