Xiao State, one of the four major countries in the Central Plains Continent, at this time, it was the reign of the fourth emperor Emperor Qingdi, and Emperor Qing had ascended the throne for 20 years, and now he is old.

Recently, Emperor Qing's health has become worse and worse, and he has fallen into a coma from time to time, and even the early dynasty has been exempted.

Therefore, everyone can see that Emperor Qing is dying, and his death is only a matter of time or time, and many ministers have stood in line, looking forward to the work of Conglong.

On the surface, the six princes are evenly matched, but in fact, smart people know that only the eldest prince and the six princes are really capable of competing for that position.

The eldest prince Xiao Qingheng was born by Emperor Qing Yuanhou, but Emperor Qing did not like Yuanhou, and after ascending the throne, he ruthlessly pulled out Yuanhou's foreign family, and within a few years of Yuanhou, he died of depression.

Although Xiao Qingheng is a son-in-law, because he was born after the Yuan Dynasty, he was not treated by Emperor Qing, and it can even be said that he grew up in the cold palace.

When he became an adult, he was crowned king early, let him go out of the palace and live there, and clearly told him that the throne would not be left to him.

Empress Yuan died, and Emperor Qing set up Lin Guifei as his successor, and the six princes were born to him.

Lin Jihou is the true love of Emperor Qing, the sixth prince Xiao Qingyu is the youngest son of Emperor Qing, Emperor Qing is naturally very fond of him, and he has been paving the way for Xiao Qingyu to ascend the throne, Emperor Qing even wanted to establish Xiao Qingyu as the prince several times, but they were all vetoed by the courtiers to establish the prince and must establish a prince.

It stands to reason that Xiao Qingheng should be the logical prince, but Xiao Qingyu is the successor and has won the favor of Emperor Qing.

But at the beginning, most people still stood with Xiao Qingyu, the sixth prince.

The biggest reason is that Cheng Wang, that is, the eldest prince Xiao Qingheng, has no help from foreign forces, and is isolated, not to mention the six princes, but also the other princes.

However, everything changed after King Cheng married Yin Yin, the daughter of a fourth-rank military attaché.

Yin Yin's father was a soldier who made military exploits step by step, and only then did he get the position of this four-rank military attaché.

At the beginning, when Xiao Qingheng asked Emperor Qing for a decree to marry Yin Yin, Emperor Qing only thought for a moment and agreed.

Emperor Qing didn't look down on Xiao Qingheng, the eldest son, and didn't care about him succeeding to the throne, so naturally he wouldn't find him a powerful outsider.

Therefore, Emperor Qing agreed, and the only daughter of the Yin family married Xiao Qingheng and became Princess Cheng.

It's just that in the next ten years, Emperor Qing didn't expect such a change.

Not long after Xiao Qingheng married Yin Yin as the princess, it was the eighth year of Emperor Qing's accession to the throne, and the Liang State launched a war against the Xiao State.

At that time, Yin's father led the Yin family to come forward, and Mao recommended himself and went to the border to start a war with the Liang State.

Xiao was weaker than Liang, and in the eyes of most people, it was undoubtedly an inevitable defeat, a difficult battle that lasted eight years, and in the end, Yin's father and his son defeated Liang, and Liang had to cede five cities.

This battle not only enhanced the national strength of Xiao State, but also made the Yin family famous in a war, and Emperor Qing had to comply with the soldiers and public opinion, and named Yin's father as the general of Zhenbei, and his surviving sons were also awarded official positions.

It was also because of this battle that the 100,000 troops in the northwest were firmly controlled by the Yin family, and the soldiers in the northwest only knew the Yin family, not the royal family.

Because Xiao Qingheng, the king of Cheng, married the only daughter of the Yin family as the princess, the power of the general of Zhenbei naturally fell on him.
