The Strongest Spirit

The girl who fell from the sky, the king who rules the world, I am no longer the only one to dominate the gods. Ten thousand years of grudges can be settled with a single sword. A shot caused thunder, a sword broke through the three realms, the emperor's flames repaired the sky and reincarnated, and a single glance angered all the ghost ministers. Let's see how the male protagonist, as a summoned beast, proves his way through killing, returns to the top of the strongest, and rules the alien continent.
