How to peel the turtle shell?

I've done this, too. I want to keep it as a souvenir. The turtles are all dead, which is not cruel. . . . . . The way I do it is relatively simple. The first is boiling. Just boil the soft-shelled turtle in water (about 10 minutes). Take it out and remove the meat. Both sides of the shell will be soft, but it doesn't matter if it is dry, it will be hard back. The second is to put the tortoise where there are ants and let them bite. It takes about a day, only one shell is left, and the other parts are eaten by ants. When the shells are done, they should be dried, not dried. After air drying, you can apply some transparent nail polish to prevent decay, and varnish can also be used. But I didn't draw anything. It's been two years now, and it's still no problem . . . . . .

Please accept it, thank you!
