First of all, thank you very much for the opinion of a friend.

Here's his opinion.

Such superstitions are really hard to accept. But

Good articles must be supported and promoted.....................

If this friend is talking about the feelings of many people, I have to affirm it.

In fact, this is not superstition, this is the background of the story, after all, some things are only reasonable if they happen in a specific background.

For example, if you're in the water, only ordinary ships (not spaceships) can function. However, if it is said that ordinary ships are used to sail on the ground, such a thing is simply incomprehensible, that is, the plot is too fake.

In fact, if you read chapter by chapter, you can discover the connotation of the work.
