I Was Reborn as a Bug in the Way of Heaven

The protagonist was the leader of the righteous path in his previous life, but when he ascended, he discovered that the entire world of cultivation was just a "luck pasture" created by the immortals in the upper world. The way of heaven is an "intelligent harvesting system" disguised by immortal treasures, and all monks are "lucky pigs". The so-called ascension is the moment of being slaughtered and refined. He resisted desperately, but was killed by the "protagonist" (the Son of Destiny) sent by heaven.
