Su Han accidentally traveled to a parallel world and became a single father, but his daughter Xiao Yue had a mysterious demonic bloodline. What's even more outrageous is that his system turns out to be "Devil Summoning" - every time he completes a daddy task, he can summon a strong demon warrior! In order to earn money for milk powder for her daughter, Su Han had to go back and forth between the workplace and taking care of her baby.
