Immortal Clan: Start with Many Children and Many Blessings

So far, it looks pretty good. It's pretty cool to start directly at the peak of foundation building. Both the protagonist and the supporting characters have online IQs. There are a few details, but it's innocuous. I hope the author can grasp the rhythm and don't write too much.

I already know how to write it after reading it, which is boring.

They have all come to your door, and they don't care anymore. Even if they only have 20 days to live, they will still marry you. What the author wrote is very poisonous! They all got married together, hahaha.

You haven't even started reading yet and you've already finished it.

The first question is the problem of telling the system. Although it is not big, it is very important. The second question is that you have hundreds of millions of spirit stones and are still the city lord. Why do you go to the Lingdan Pavilion to refine elixirs? I don't understand this. Isn't there a place for alchemy in your mansion? Even if there is not in your mansion, you don't have an industry for alchemy? Do you just rely on rent collection and salary?
