Please make it clear, how old does the immortal ask his disciples to become monks? And let disciples take this as their profession?

This is not business. Being a horse is dependent on the fairy family to see things. To put it bluntly, you can use your body to complete their tasks. Basically, they are immortals and need to be cultivated. And if you treat the old fairy family as a business, collect a lot of money and do something you shouldn't do, the cause and effect will all be borne by everyone. Some old immortals are strict with their disciples for this little brother's horse. Because sometimes the interests are in front of us, it is difficult to understand what is right. Time is different, there is a long time, mostly a few years.
