Does King Mangu's Thai Sting symbol work? Is there any basis for the thorn symbol?

Every master has his own method, but every master can use a general method. There are also some spells that are designed according to his own method, and then bless the mantra of the Heart Sutra of his own method. Just like the Nine Pagodas, these are handed down. Others can't be said to be groundless, but all of them have a certain effect with the blessing of experts ~ I felt quite good when I stabbed Lu Shi. Hope to adopt ~
