Novels are like this, even if they are based on reality, the author can't help but YY, they all say that the author is the protagonist's hanging, and it's the same in any book.

In the previous content, I changed the iron plate to a copper plate, and if the copper alloy is used, it must be more stable than the iron plate. As for whether it will be bad, I am going to ask my attending doctor to see his opinion.

In addition, if you have any opinions, you can put them forward, as long as they are as pertinent as this book friend, I will accept them and improve them.
