Carefully and considerately

"So, tell me a little more about how you want to have kids with my sister," Lex said, focusing on the old geezer in front of him. Earth Immortals had no effective lifespan, living in perpetuity, and so the only way for an immortal to look older was that if they became immortal at an old age, if they went through significant life experiences which aged them mentally and therefore physically.

But even if Lex ignored both those reasons, the fact that he was at the peak of the Earth Immortal realm meant that he must have spent quite a lot of time cultivating. At the very least, even if he became an immortal on the day he was born, he had to have spent ninety years to reach the ninth level of the Earth immortal realm.

For such an old man to be coveting his sister who was barely in her twenties… okay, well, maybe she was nearing thirty now, but she was a cultivator and for them thirty is basically a teenager. The point was that it was gross.
