How to Create and Setup Sub Domain In Blogger (blogspot) Blog from Custom Domain?

Who already have a blog with a domain / custom domain or also called TLD (Top Level Domain), you can also create several sub domains from the parent domain or custom domain that you use. This is useful if you have another blog that you want to link to a domain / custom domain so you don't need to buy a new domain anymore and it's quite useful to save your expenses.

For example, the domain / custom domain address that you have is https://www.yourdomain.com and if you want to add another blog for example with a niche Technology, you can add sub domains with the name Tech or techno (https://tech.yourdomain.com).
