After I Can't Go Home, I Become the New Devil

Lin Yuan just wanted to go home. Three years after he was summoned to a different world, he narrowly escaped death in the forbidden area and relied on the "Going Home Assist System" to become the strongest, just to open the passage home.

The king smiled and said: "What good is there in that world? Stay and I will give you whatever you want." Lin Yuan knelt among the debris and cut his fingers to pieces, unable to make his way home. "I just want to go home... Just go home..." When the last fragment slipped from his fingers, he stood up, the last light in his eyes extinguished. What will the ending of this world be like?
