All Immortals Like to Eat It, but I Have the Coffin to Bury the Immortal to Swallow It

This world is a huge mess. Only worthy people can live. The people around you or monsters pretending to be humans are all trying to make you laugh, eating people without spitting out their bones. Su Hao, who had just entered the world of immortality, obviously didn't realize this, so he was successfully betrayed in a mission and eventually died. It's a pity that this death allowed him to successfully obtain a coffin from the ruins, so he began to swallow it endlessly, burying the body to extract its essence, and sacrificing the treasure's aura to enhance his cultivation. Everything will become nourishment! What? You say I am immoral! Oh, forget about you liver-eating hypocrite! Then... I will reluctantly give you a ride!
