Taking the Demon Lord to Practice Immortality, All the Villains in the Family Went Crazy

After arriving at Ta Temple, he found that this place was different from what he had imagined. Is this villain's whole family of misbehaviors just a joke?

So he took the Demon Lord to start cultivating immortals. Who knew that all the villains in the family started to go crazy? This... Is illogical! It's logical not to call him a villain, but the Demon Lord seems to be quite normal. But when he slowly came to his senses, he realized something was wrong. Wasn't that a cultivation novel? Why has my innocence been lost? Ah! It turns out that the most abnormal thing is the Demon Lord...
