What is the difference between Xuanwu and Kirin?

Kirin is a kind-hearted, powerful creature, who knows the way of the world and God's will and can listen to destiny. There are twelve countries in the human world, ruled by twelve kings respectively. Kings are not judged by birth or merit, but by fate. Kirin is a god beast that conveys destiny and chooses a king for the country. Xuanwu is a spiritual thing composed of turtles and snakes. Xuanwu originally meant Xuanming, and the ancient sounds of Wu and Ming are interlinked. Wu means black; Ghost means yin. At first, Xuan Ming described the turtle divination as follows: the turtle's back is black, and the turtle divination first invited the turtle to ask questions in the underworld, brought back the answers and showed them to the world in the form of divination. Therefore, the earliest Xuanwu is the tortoise. Since then, the meaning of Xuanming has been expanding. Turtles live in rivers, lakes and seas (including turtles), so Xuan Ming became a water god; The tortoise lives long, and Xuan Ming has become a symbol of immortality; It turns out that the underworld is in the north, and Oracle Bone Inscriptions's divination in the Shang Dynasty is "divination must go north", so Xuan Ming became a northern god again.
