[High martial arts + upgrade flow + decisive killing + strong country] Li Yao, who had just traveled through time and became a death row prisoner, was about to serve his sentence, but found that he had awakened the [Taotie Cauldron]. By consuming his lifespan, he could instantly refine all things and improve himself! In this world, Daxia is an apocalyptic world where great powers divide the country and warlords run rampant! Not only that, this world is full of martial arts! There are even demons and troubles! The strongest ones are all great powers and warlords! The consulates of the ten-nation coalition took control of local governments, established concessions, and eroded Daxia! Li Yao was a mortal with a lifespan of only a few decades.

What kind of iron and wood are you swallowing? You should swallow the demon! Kill! Kill the bully! Kill the warlord! Kill the great powers! Kill the monster! Create a clear and clear world!

Facing a million-strong coalition of powerful powers and world-destroying demons, he calmly chanted: "You guys, would you like to test the sharpness of my sword?"
