On a moonlit night, a blue figure walked rapidly to the top of Mt. Fuji at the foot of Mt. Fuji. Yes, the figure walked at a peculiar pace, but as fast as a phantom. The blue figure soon reached the top of the mountain, and he opened his arms and smiled at the scenery under his feet, "Time flies so fast!" This is a young man of fourteen or fifteen years old, with black hair and red eyes. It glows in the dark.

Mu Feng, the sole heir of the Moonlit Night family. I have been living at the foot of Mt. Fuji in the island country for 15 years. The Moonlit Night family is one of the few hermit families in the island nation. Behind the scenes, the four major families of Hattori, Kitahara, and Fengbo control the four major sections of the island country's economy, politics, military, and education. Many of the policies and measures of the island nation must be discussed by the four families before they can be implemented. In fact, these four families all have an unknown power - ninjutsu.

Ninjutsu is a type of assassination technique that originally originated from the traditional fighting techniques of island nations. An early ninja with a nature similar to that of a spy assassin. Therefore, ninjutsu includes killing, creating chaos, self-cultivation, and gathering intelligence. Ninjas at that time were based on li. And the development of Iga, Koga, Kii and other ninja organizations. At that time, he was known as the number one master in the ninja world, and the Iga-ryu ninja Hattori Kiyota was even more outstanding. Under the leadership of Hattori Kiyota, Igari's mission completion rate has reached an unprecedented 100%.

Hattori Kiyota, a low-key but arrogant man. As Ihori grows, his heart has changed from a low-key to an unstoppable one, and he thinks there is nothing he can't accomplish. However, at that time, the island country was subordinate to China and belonged to the vassal states of China. Paying countless tributes of gold and silver every year, Hattori Kiyota actually accepted a very dangerous mission at this time, assassinating the Huaxia Emperor. However, this mission brought devastating disasters to Ihori and the entire island ninja. As an ancient civilization that has been inherited for thousands of years, Huaxia has the power to make the world feared - ancient martial arts.

A group of people who live in seclusion but always pay attention to the fate of China, the ninjutsu of the island country is as vulnerable as a baby holding a toy in the eyes of the ancient warriors of China. When the arrogant Hattori Kiyota swaggered in front of the eyes of the Huaxia Emperor, the ancient warriors appeared, and they just waved their hands and severely damaged Hattori Kiyota who came to assassinate him. Subsequently, an ancient warrior named Desperate went to the island country and single-handedly wiped out the entire island ninja. For a moment, the hidden power of the world was shocked.

Hattori Kiyota escaped back to the island country by luck and faced the broken ninjas. Kiyota Hattori's arrogance shattered. He couldn't forget the strength of the ancient warriors, and longed for that kind of power. Ten years later, a genius in the martial arts world appeared. His performance made the ancient Chinese warriors scramble for it. In the end, he worshiped Kunlun Immortal Mountain, the most powerful ancient martial sect at that time. In just a few years, Bu Xiangwu has learned the essence of ancient martial arts, and he has come out of the blue. Even his master, the head of Kunlun Immortal Mountain, openly admitted that he was inferior to his apprentice. When the Master suddenly decided to travel far away, he passed the position of head to Bu Xiangwu.

Bu Xiangwu is also really powerful, and less than five years after ascending to the position of leader, he is known as the first person in the ancient martial arts world. However, the good times did not last long, and a few years later, he invited the major ancient martial arts sects and families to Kunlun. Comprehending the ancient magic skills he obtained by chance, the masters of all sects went one after another. After that, Kunlun Mountain announced the closure of the mountain, but there was no news. The only remaining disciples of each major sect went to check one after another, but they could not find the entrance to Kunlun, all because Kunlun was the best sect in the art of Qimen Dunjia today after the fall of the ink master. Immediately after that, due to the lack of masters, the news of each sect being wiped out by a mysterious force came one after another. The rest of the sects were all in danger and took refuge in seclusion one after another.

Some sects reacted in time to avoid the disaster, but some small sects could not avoid it, Lin Zhengnan was a little disciple of one of the sects, maybe because the person who came was too arrogant, he escaped the catastrophe, but he found that the person who came was the first person in Guwu to step south. Shocked at the same time, it quickly descended the mountain. Thinking of his fellow relatives who were tortured and killed, Lin Zhengnan was grief-stricken, but the psychology of revenge burned in his heart. Lin Zhengnan, who concealed his name, found Bu Xiangwu, the former first person in ancient martial arts, who was the son of Hattori Kiyota, the first ninja in the island country, Hattori Xiangwu. The purpose of his coming to Huaxia was to destroy the ancient martial arts of Huaxia.

In this way, the ancient martial arts of Huaxia were destroyed, but the ninjas of the island country gathered together because of the appearance of Hattori Xiangwu, forming four families headed by Hattori. However, after the death of Hattori Mutotake, the four major families quickly split. They fought with each other endlessly, but Lin Zhengnan took this opportunity to change his face and join the Moon Night family. And use the resources in his hands to collect some orphans of the talented Yi Bin in Huaxia and join him to replace some newborns in the Moon Night family.

In the face of the powerful Ninja Sect, Lin Zhengnan felt that with his own strength, he would never be able to complete the plan to subvert the Ninja Sect in his lifetime. So when he was dying, he endured his last breath and warned his juniors that they must keep in mind the blood feud between Huaxia Guwu and Ninja Sect, and never forget to avenge the destruction of Huaxia Guwu.

Time flies, several generations have passed, and the descendants of the Lin family have lived in this familiar and unfamiliar island country for 11 centuries. Some people say that time is the antidote to hatred, but the truth is not absolute, the Lin family has not forgotten the ancestral teachings, and has not forgotten hatred. They relied on some of the five elements techniques left by Lin Zhengnan back then, and stubbornly fought against the Moon Night family. However, with the development of science and technology, it has become more and more difficult to realize the practice of changing the tanuki for the prince back then. Mu Feng is the only one of this generation who has succeeded.

Mu Feng began to practice the ninjutsu of the Moon Night family at the age of 5, from the most basic physical arts, to the seal to perform ninjutsu, it has been a full decade, in this ten years, Mu Feng has shown a ninjutsu talent that surpasses others, and has been unanimously praised by several teachers who taught him ninjutsu, and slowly Mu Feng's genius name has also spread far and wide.

For his safety and for the revitalization of the family, the Moon Night family has never let him leave the family's territory, so none of the other families of the Ninja Sect have seen what this ninjutsu genius looks like. Under such strict protection, of course, it also made Mu Feng more distracting, on the day he was 14 years old, the patriarch personally announced that the next year he would be given an examination for ninjutsu practice, and if he passed, he would be recognized by the people in the family, and he could also start to formally contact the family industry.
