The four guards are the well-known Spring and Autumn Four Friends in the rivers and lakes. They were originally from the rivers and lakes, but because they lived in the south of the Yangtze River and had a similar temper with Li Yu, they originally intended to help Li Yu to protect the southern Tang Dynasty.

The four of them were originally from the rivers and lakes, why could they have the same temperament as a dignified monarch?

It turned out that Li Yu was originally the sixth son of Li Jing of Yuanzong of the Southern Tang Dynasty, and when it came to inheriting the throne of the Great Unification, it would not be his turn. But for some reason, Li Jing's second son to fifth son died early, and later, in addition to the eldest son, there was also the then crown prince Li Hongji, and only he Li Yu was left.

At that time, Li Yu was still young and had no cronies at all. The crown prince Li Hongji has many henchmen, and Li Yu's life is in the hands of Li Hongji at any time. It can be said that people are knives, I am fish and meat, people are pots, and I am elk.

There was a personal eunuch named Jiang Dahai, and he learned from other eunuchs that Li Jing's four sons were secretly killed by Li Hongji. Since then, Li Hongji has never threatened again. Now Li Yu is still young, if he is older, who knows if he will become Li Hongji's "fish and elk"?

Jiang Dahai followed Li Yu and served him since he was a child. The two are both retinues and playmates. He gave Li Yu an idea, that is, to let Li Yu concentrate on the piano, chess, calligraphy, and painting from now on. And no longer participate in political affairs. In this way, we have been on guard against Li Hongji's suspicions.

Since then, Li Yu has abandoned political affairs and concentrated on things other than political affairs, and after a long time, he is really interested in it. Li Yu is inherently intelligent, and he knows that things that others may not learn in their lifetime are very refined in just a few years, and some even months.

After a long time, Li Yu has been in the piano, chess, calligraphy and painting, medicine and astrology, craft miscellaneous, trade and planting, and all of them are not proficient. A special puppet show with its own unique insights and innovations.

The crown prince Li Hongji saw that Li Yu was just a plaything and a discouraged son, so he really no longer guarded against him, and asked his father Li Jing to make Li Yu the Duke of Anding.

After Li Yu became the Duke of Anding, he left the palace and gave another mansion. In this way, Li Yu is more like a fish in water, travels every day, makes friends and visits, and is at ease. The Four Friends of Spring and Autumn were met by Li Yu at this time.

Although the four friends of the Spring and Autumn Period are people in the martial arts, they belong to the literary people in the martial arts. Not only are they strong in martial arts, but they also have their own unique skills.

The reason why the four friends of Spring and Autumn are called the Four Friends of Spring and Autumn is based on their names - the eldest has long hair in spring, the second has long hair in summer, the third has quiet autumn water, and the fourth has cold wind in winter.

The boss has long hair in spring, writes well, and is good at danqing, landscape figures, feathered flowers, and are all exquisite. The brush in his hand can not only be used for calligraphy and painting, but also as a weapon.

The second summer solstice is long, and he has an iron folding fan in his hand. This is also his weapon, and it is also an indispensable thing for him to play with when he reads and writes poetry at any time. He is a good reader, has hundreds of schools, sees everything, and is a very learned Confucian.

The third autumn is quiet, he is the best at long sounds, an iron flute in his hand, usually when he is fine, he always takes it out to blow a moving tune, once he encounters a strong opponent, the iron flute is a sensitive and abnormal weapon.

The fourth child is cold in winter, he likes to play Go, and today there are few opponents. He used the chessboard as a blade, and the chessboard was made of magnets, so that when he was studying chess, whether he was sitting or lying down, he suddenly thought of a chess move, and he would use black and white pieces to make a cloth, even if he was in the middle of the rook, he would not move and fall. And the black and white chess pieces naturally used hidden weapons.

The four of them boast that they are invincible in these aspects, who would have thought that since Li Yu became the Duke of Anding, he often meets friends with literature, and his reputation and talent are rarely heard of in the martial arts, but he stands out among the literati and writers in Jiangnan, and his reputation spreads far and wide.

Li Yu's name spread to the ears of the four friends of the Spring and Autumn Period, and the four of them were naturally unconvinced. So by chance, the four friends of Spring and Autumn met Li Yu. The four friends of the Spring and Autumn Period each competed with Li Yu based on their strengths.

Who knows, Li Yu is proficient in everything and outstanding in everything. Although he was tied with the four, the four of them knew that it was Li Yu who gave the four of them face. And even if it is a tie, then Li Yu will already win the game by competing with the strengths of the four.

The Spring and Autumn Four Friends admired talented people the most in their lives, not to mention that Li Yu's talent, the strengths of the others, and his own unique innovation, made the Spring and Autumn Four Friends admire the five bodies. Later, the four friends of the Spring and Autumn Period decided to play for Li Yu, and from then on, before and after the saddle, they never left and right.

Coincidentally, it is no coincidence that the matter of the crown prince Li Hongji framing his siblings somehow reached the ears of Li Jing of Yuanzong of the Southern Tang Dynasty, although there is no conclusive evidence to prove that those brothers were killed by the crown prince Li Hongji, but there is no wind and no waves. Since the crown prince Li Hongji is so sinister, how can he be made emperor?

Later, when Li Jing of Yuanzong of the Southern Tang Dynasty was dying, he unexpectedly appointed his younger brother Li Jingsui as the heir to the throne.

In this way, it angered the crown prince Li Hongji, who had already made friends with his henchmen in private, wooed the ministers, and immediately consulted with his cronies. Among the staff of the crown prince Li Hongji, there are several who are proficient in medical skills and several who are strong in martial arts. One of them, who made poison, and another person with strong martial arts, went to Li Jingsui's palace overnight, and added poison to his medicinal diet without knowing it. Li Jingsui was poisoned and died the next day.

Although it was not found out who poisoned Li Jingsui in the palace, it proved that Yuanzong Li Jing's suspicion was not wrong. As soon as Li Jingsui was appointed heir to the throne, he was poisoned and died, which was of course poisoned by the person who had the most to do with the heir to the throne.

Although Li Jing of Yuanzong of the Southern Tang Dynasty only had one breath, he was not confused, and that night, he recruited Li Hongji into the palace to serve and gave Li Hongji the imperial meal, Li Hongji did not expect that there would be a crane top red in this imperial meal. After eating the imperial meal, he died violently when he returned to the mansion that night.

On the second day, Li Jing of Yuanzong of the Southern Tang Dynasty died. When he was dying, he got rid of his own son first, so that he could overcome the trouble.

Within three days, three royal families were killed in a row. The heir to the throne naturally fell to the head of Li Yu, the Duke of Anding.

At first, it was only because he was afraid that the crown prince Li Hongji would be suspicious and did not dare to participate in political affairs. But after these years, the interest lies in the beautiful landscape, and the energy is in the qin, chess, calligraphy and painting, medicine and astrology, craft miscellaneous, trade and planting. I really have no interest in politics.

The four friends of the Spring and Autumn Period naturally became Li Yu's personal guards, these four friends were originally from the martial arts, and they were very obsessed with calligraphy, painting and chess, but they were as indifferent to political affairs as Li Yu, and never persuaded him to care about the government.

In this way, the major events in the DPRK and China naturally fell on the body of Situ Zhouzong of the Southern Tang Dynasty.
