After Four Ninja Battles, the Eight Gate Kicks Woke Me up from the Suspended Animation.

Thousands of years ago, Liu Shenyue traveled through the world of Naruto and became the first immortal to discover natural energy, making him invincible in the world. He once raised a toad, released it in the mountains, and taught it the power of prophecy. He once raised a white snake, released it in a cave, and taught it its dark power. He once raised a slug, buried it in the forest, and taught it the power of life. Later, the mountain where the toads lived was called Miaomu Mountain; the cave where the white snake lived was called Longdi Cave; and the mountain forest where the slugs hid was called Shigu Forest. He also transformed into the emperor of his ancestral country, met and fell in love with Princess Kaguya, a foreign race, and gave birth to the source of the destined children: Otsutsuki Hagoromo and Otsutsuki Hamura. Thousands of years later, the world only knows that the emperor of the ancestral country is dead, and no one knows who Liu Shenyue is. In the Fourth Ninja War, a red "Ye Kai" tore apart the era of ninjas. He was awakened! This novel and its characters are purely fictitious.
