Huh? I’m About to Die, and the System Wants Me to Have Lots of Descendants

Not only is it a clever book, but it's also very poisonous. I just couldn't read it after reading more than a dozen chapters. 1. Even if a Golden Core monk loses his skills due to old age, he won't need help to walk, right? 2. The protagonist who has returned to the foundation building stage cannot confirm whether his wife or concubine is pregnant. He has to ask a doctor to check her pulse to confirm. 3. Communication with the system requires verbalization. You can say that the protagonist deliberately exposed the system in front of others, but the other party came into the protagonist's house as an undercover agent to investigate. Don't they know the reason for carrying a jade?
