Save the World by Summoning the Succubus

Twenty years later, Wenxuan has already concluded that he lives in an ordinary world. Until tonight, a ridiculous playful ritual actually summoned a succubus. The dog that lives together day and night claims to be an ancient being that has lived for hundreds of years... The old worldview collapsed in an instant, and the dreamed of extraordinary power arrived as expected... But why is the price of transforming into an angel a shameful transformation into underwear? ! What's even more outrageous is that the hundreds-year-old monster told him: Want to save the world? Let's have a love affair first! So... Let's begin our love war!
