Start Traveling Through the World of Substitutes and Become a Substitute Messenger

He accidentally traveled to the world of substitutes and got his own substitute, but found that the beautiful life he imagined did not exist at all. What greeted him was either pain or separation. Caught between the alien species in the abyss and the so-called gods, all the races in the world are struggling to survive, just to find a glimmer of hope. Since there is no hope, then it is up to me to be the glimmer of hope. Suppress the abyss, kill the gods, and save all races from water and fire. I heard that you are unwilling to cooperate, so I'm sorry, your race is not among all races.
