[Decisive killing + system flow + passionate martial arts + global catastrophe]
A hundred years have passed since spiritual energy revived, alien races tore apart space and descended on the earth, and humans used martial arts to fight against natural disasters.
Delivery boy Ye Xiao awakens to the [Infinite Upgrade System]. He reaches the full level in seconds while others have to work hard for ten years to break through the bottleneck!
"Ding! The basic boxing technique has been upgraded to "Nine Layers of Heaven Collapse Fist"!"
"Ding! The Tetanus Dagger has been upgraded to the [God-killing Immortal Blade]!"
When the foreign monarch comes across the starry sky and warriors around the world despair——
Ye Xiao stepped on the corpse of an SSS-level ferocious beast and pointed his sword at the sky: "My sword has been upgraded 90,000 times. Can you catch it?"
From the slums to the top of the world, from warriors to god-killers, this is the ultimate legend of one man guarding the country!
