I Am an Unknown Sword Cultivator

In the universe numbered two, a dispute occurred that lasted almost eternity. The last victorious creature: man, did not get what he wanted. But after this war, the status of "humanity" in Two Thousand Universes and One Thousand Moments Trees reached its peak. But after the peak, there must be decline. Weak races with different group characteristics and thoughts cannot stay in the canvas called "the world" forever. They are the rich ink on the canvas, but the ink is not as good as embroidery after all. After passing through the chaotic loophole era of the 'Invincible Frame', the last bright light that humanity shone on finally slowly faded away. But... The real 'main line' has just begun.
