I once met a man who said that he had a silkworm lying operation before, and after only three years, he was deformed. Silkworms are basically born. Some people disappear the day after tomorrow, but no one grows the day after tomorrow. Mainly depends on your surgical skills. Try to find a better one. This comparison does not require too many steps, but it shapes muscle tissue, so some of them are poorly done. Please adopt or ask.
