Ask for the name of a novel

A man had transmigrated to a younger sister. In that world, one could only cultivate immortality if one had an immortal encounter. The immortal encounter in his sister's hand was a fish-shaped stone. When she was taking the immortal encounter examination and climbing the mountain, his sister was injured. He had obtained a medicinal pill, but it was too big. He wanted to feed it to his sister with his mouth, but the medicinal pill melted as soon as it entered her mouth. The protagonist realized that he was not the only one who had transmigrated. There was someone else who had brought an old man. The test of immortal destiny was like climbing a mountain and sitting on a mountain to enter an illusion, but he came out in an instant.
