Demon Guardian in the Multiverse

The first novel so don't be too hard on me. Will read the critics. Just writing this novel for myself. If you enjoy it ??. if not criticism so I can become better. Our unlucky MC dies accidentally was put to two options. Option 1 Realm of Warriors Option 2 Reincarnation in a World the Godking wants him to be with the power the Godking bestows to him. So no free beans for someone interfering in the work of his wife. OP from the Start. System only shop and mission. Can't show real power because of society in the first World he is. Don't own anything of this novel just my OCs and a little plot. Pic isn't mine too. Warning: Irregular chapter but I will complete at least the first book. It may take some time.
