The fierce battles of the Xia army against the Qigu and Turkic people on the Mobei steppe did not seem to have any effect on the Sui Empire further south, and the two sides continued their own directions after touching at a certain point as if they were two intersecting lines.

Wang Ze knew that this was naturally impossible, so while the Xia army launched an operation against the Mobei grassland, he never gave up the intelligence reconnaissance within the Sui Empire, and he soon learned the fundamental reason why the Sui Empire did not interfere too much in the Mobei war.

It is not that the monarchs and ministers of the Sui Empire have lost their vigilance against the increasingly powerful Xia Kingdom, but because of a major event that occurred between Emperor Wen of Sui and Empress Dugu in the Sui Empire, which involved the energy of Emperor Wen of Sui and many ministers for a long time.

This major event was caused by Emperor Wen of Sui's favor of a palace maid Chi Shi, and it also set off a storm within the entire Sui Empire.

In the spring of the thirty-seventh year of the Xia calendar, Emperor Wen of Sui Emperor Yang Jian was fifty-five years old at this time, and even Queen Dugu was fifty-two years old, because Queen Dugu was getting older and older, and she could no longer meet Yang Jian's physiological needs, so he tried to pamper the palace maid Wei Chi.

The young girl's youthful and beautiful body made Yang Jian very satisfied, although he still loved his wife Queen Dugu, but wouldn't it be more wonderful to have a fresh body to enjoy, but he didn't expect Queen Dugu's character to react when he learned about it.

The news was soon learned by the Dugu clan, and while Yang Jian had just gotten up to go to the court, the furious Queen Dugu rushed here and hanged Wei Chi, who had not yet crawled out of the bed, to death, finally maintaining the fact that she was Yang Jian's only woman.

In many deductive scripts, Queen Dugu is described as a vicious and sinister poisonous woman, but whether it is "Zizhi Tongjian", "Book of Sui" and "Northern History", they only describe the incident of her killing of Yu Chi this time, and there is no other record.

It also shows that this incident is an overreaction under Queen Dugu's anger, and Queen Dugu is not abusing and killing palace maids, in her opinion, if she wants to keep her husband by her side, she can only physically eliminate Yu Chi Xiaomei.

Although Yang Jian loves his wife Queen Dugu, Yu Chi is also his freshly pampered little beauty, otherwise how could he look at it?

In the past, because of Dugu Jialuo, he had no other women for decades, and at this time, he finally fell in love with someone he liked, and he was probably thinking about it even when he went to court, but at this time he suddenly learned that the little beauty had been killed by Queen Dugu.

Even the corpse had been disposed of, and Yang Jian was furious when he learned about it, so he quickly returned to the palace to reason with Queen Dugu.

However, at this time, the Sui Dynasty still had the legacy of the high status of Xianbei's wife during the Northern Dynasties, coupled with Yang Jian's spoiling of Queen Dugu for decades, after Queen Dugu's quarrel, Yang Jian actually did not win, and Yang Jian, who was angry, ran away from home in the middle of the night with his bare head and not even wearing shoes.

If it weren't for the guards following all the way, I am afraid that Emperor Wen of Sui Yang Jian would have thrown himself into the water and died, after Gao Ying and other important ministers hurriedly arrived, Yang Jian said with grief and indignation: "There is nothing more powerful in this world than not being able to protect even the woman you like!" ”

In fact, Queen Dugu's approach was not strange at the time, but it was a common thing in the royal family of many ministers, and this seemingly radical behavior was also related to Queen Dugu's life experience.

In the first year of Emperor Xiaomin (Yuwenjue) of the Northern Zhou Dynasty (557 AD), the bride who had just been married for more than a month, Dugu Jia Luoshang, was immersed in the shyness of being a new wife, and the fierce political struggle within the Guanlong Xianbei military group involved the family of Queen Dugu.

At this time, Yuwen Hu, the minister of the Northern Zhou Dynasty, was in power, because Zhao Gui, one of the Eight Pillars, was dissatisfied with the young Yuwen Hu, and when he was in power, he tried to win over Dugu Jialuo's father Dugu Xin to rebel together, although Dugu Xin also had his own desires, he did not believe that Zhao Gui could succeed, so he did not agree to Zhao Gui's request, but he did not tell the truth.

However, Zhao Gui couldn't succeed after all, after his rebellion failed, Dugu Xin was also involved for this reason and was feared by Yuwen Hu, and soon Dugu Xin failed in the political struggle with Yuwen Hu, the powerful minister of the Northern Zhou Dynasty, and the whole family was killed, and only two married daughters were not liquidated.

Overnight, Dugu Jialuo fell from the noble daughter of the top family of the Eight Pillars of the Northern Zhou Dynasty to the daughter of a sinner whose parents died, the family was scattered, and she was alone.

Generally speaking, Dugu Jialuo is the daughter of a criminal minister, and many husbands not only will not protect such a woman, but will even use her as a vote to kill her on their own initiative, in exchange for the favor of the new authorities, but Yang Jian, who was only seventeen years old at the time, resolutely resisted the demands of others.

So when he was young, he was not only implicated in the Dugu Xin incident, not only did he have no career prospect to speak of, but his life was often threatened, but Yang Jian tried to protect his helpless little wife who was only fourteen years old with his shoulders, and he vowed to love her for the rest of his life.

Later, the history books commented on it: "At the beginning, Gaozu and Dugu were very in love with each other, and they swore that they would not be born of a different son."

Of course, Yang Jian was able to protect his little wife, and gradually became an important minister and held power in the future, also because he had a father Yang Zhong, who was also a member of the Eight Pillars Kingdom, but in any case, the relationship between Yang Jian and Dugu Jialuo was sincere.

By the time Yang Jian seized the power of the Northern Zhou Dynasty step by step and became the emperor, Empress Dugu was already thirty-eight years old, and Emperor Wen, who had never had a concubine, still infinitely indulged Empress Dugu's caution and careful thinking as a woman and wife: he was not allowed to have concubines.

It is said that there are not three thousand beauties in the harem, but it is normal to have dozens of them, but as the most powerful emperor in the world, Emperor Wen of Sui Yang Jian not only has six palaces and no attendants beside him, but also plays tricks on the harem system by Queen Dugu.

The history contains "the literature queen merit to participate in the test, the external pre-government, the internal palace is good at the palace, the heart of jealousy, the position of concubine, no three concubines...... and inhibit the obedience and downgrade its rank".

That is to say, Queen Dugu formulated a very unreasonable internal and external life system with sexual jealousy and concubines, so that after her death, Emperor Wen of Sui and later Emperor Yang of Sui had to revise the harem system.

According to historical records, Emperor Wen of Sui and the empress had a very close relationship: "Every time the upper dynasty is approached, the latter and the upper chariot enter, and the pavilion is stopped." So that the eunuchs served, the government was lost, and then Kuang admonished, and many benefits were promoted. Waiting for the retreat from the dynasty and the same anti-Yan sleep, looking at each other happily. ”

Thinking back to a thousand years ago, when Emperor Wen of Sui went to the court, Queen Dugu sent him to the court, and then waited outside the court, and asked the eunuchs to listen to the words and deeds of Emperor Wen of Sui.

When Emperor Wen went down, she accompanied Emperor Wen of Sui back to the palace, and I am afraid that when Emperor Wen of Sui saw the gentle and sweet smile of his beloved wife who was already waiting for him to go back to dinner, he couldn't help but respond with a smile.

Emperor Wen of Sui and the queen of the night clothes and food after this warm and sweet fragment of life, the scene at that moment condensed the tenderness of a thousand years, but this time Emperor Wen Sui's behavior finally hurt his beloved wife.

After all, Queen Dugu was in her fifties and could not meet the needs of Emperor Wen of Sui, so Emperor Wen of Sui was also a little cautious, wanting to find one or two beauties as a life adjustment, so he tentatively pampered the palace maid Wei Chi, but he didn't expect the queen to kill this woman angrily with grief and anger.

Emperor Wen of Sui felt that the emperor's dignity had been hit in a fit of anger, and he ran away from home in a bad temper, and the entire Daxing City was extremely nervous by this incident, and even for several months, Daxing City would issue an order for a curfew in the whole city.

Fortunately, Emperor Wen of Sui Emperor Yang Jian and these ministers are quite sophisticated, and they know the relationship between Yang Jian and Queen Dugu very well, and they quickly persuaded Yang Jian to return to the palace, and the relationship between Yang Jian and Queen Dugu has been decades after all, and it is not comparable to the Wei Chi clan who has just been spoiled once, and the couple who have been deeply affectionate for many years quickly reconciled.

However, Emperor Wen of Sui did not expect that Queen Dugu, who had always been favored by him and had a proud and stubborn personality, had been deeply hurt and miserable in her heart, although she temporarily forgave Yang Jian, but her body quickly collapsed and died a few years later.

Wang Ze also sighed again and again after learning what happened in Daxing City, it was a pity that the relationship between the two for many years was really a pity, but since the Sui Empire no longer had so much energy and time to meddle in the war in Mobei, it was just right that Xia Guo could take this rare opportunity to continue his strategy.

At this time, Yang Jian didn't know the seriousness of Queen Dugu's incident to the Sui Empire in the future, but he loved his wife, and he was also annoyed when he saw Dugu's increasingly sick body, but the matter had been done and there was no turning back, so he could only take care of his wife in person all day long.

In such a situation, the upset and irritable Yang Jian was not in the mood to deal with political affairs at all, so he asked the crown prince Yang Yong to follow Gao Ying, Yang Su and others to deal with political affairs, but Yang Guang, the king of Jin, followed Yang Jian all day and night to take care of his mother, and in just one month, he described it as withered.

Emperor Wen of Sui didn't like the extravagance of the crown prince Yang Yong, and Queen Dugu didn't like the good woman of the prince Yang Yong.

At this time, seeing that her youngest son was taking care of her day and night, her eldest son Yang Yong rarely came to visit under the pretext of being busy with political affairs and even for several days, so the balance in her heart, which originally favored her youngest son, tilted towards Yang Guang.

As time passed, the idea of hoping that Yang Guangli, the king of Jin, would become the crown prince gradually gained the upper hand, and in the future, it had a strong impact on Yang Jian.

The impact of the Dugu Empress incident was only a few months, but the impact on the entire Sui Dynasty was great, but the Sui Empire did not interfere too much in the Mobei War, in addition to the emotional dispute between Emperor Wen of Sui and Empress Dugu, there was also a very important reason, that is, a very serious famine suddenly occurred within the Sui Empire.
