Cảm nhận của anh/chị về đoạn văn sau:

…Trọng Thủy nhận dấu lông ngỗng mà đuổi. Vua chạy tới bờ biển, đường cùng không có thuyền qua bèn kêu rằng: “ Trời hại ta, sứ Thanh Giang ở đâu mau mau lại cứu” . Rùa Vàng hiện lên mặt nước, thét lớn ” Kẻ nào ngồi sau ngựa chính là giặc đó! ” . Vua bèn tuốt kiếm chém Mị Châu, Mị Châu khấn rằng:  “Thiếp là phận gái, nếu có lòng phản nghịch mưu hại cha, chết đi sẽ biến thành cát bụi. Nếu một lòng trung hiếu mà bị người lừa dối thì chết đi sẽ biến thành châu ngọc để rửa sạch mối nhục thù”. Mị Châu chết ở bờ biển, máu chảy xuống nước, trai sò ăn phải đều biến thành hạt châu. Vua cầm sừng tê bảy tấc, Rùa Vàng rẽ nước dẫn vua đi xuống biển.
