Compared to the gains to be had from conquering the Longevity World, the sacrifices Mo Longxuan promised here were merely a drop of water on a hot stone.
Furthermore...
Mo Longxuan probably didn't think a True Immortal in the arena could suffer much loss.
After all, in his view, he was already at the end of his tether, unable to spare much strength to deal with the True Immortals and Void Immortals involved in the assault.
With this thought, Gu Jinlai no longer showed any mercy.
The South Fire Divine Light kept firing, like a Giant Sword five hundred meters in diameter and tens to hundreds of miles long, constantly swinging and sweeping through the arena.
With each sweep, inevitably several Void Immortals, and even True Immortals, fell.
He could clearly hear that Mo Longfei, a Profound Immortal from the Mo Family, was on his way.
Despite not knowing what cultivation level Mo Longfei had attained, underestimating his opponent was akin to being irresponsible with his own Life.
