Xiao Yuchuan has been forced to guard the Mo clan over the years, but instead of cultivating his new power in the north, he has made the Xiao family's momentum in the court worse day by day. Many families who have been trampled under the feet of the Xiao family are now above the Xiao family, and even the position of the crown prince is in jeopardy. Xiao Yuchuan is not indifferent, but has been waiting for a desperate opportunity to survive.

The northern tribes have coveted the Central Plains for a long time, and now is a good time for them to regain their strength.

Emperor Xuanwu also knew that this was an excellent time to take back the Xiao family's military power. But this time the northern barbarians came prepared, if Xiao Yuchuan was really let go, not to mention that the big war was imminent, tens of thousands of soldiers under Xiao Yuchuan lost the backbone of Xiao Yuchuan, and the army was unstable, so it was said that Xiao Yuchuan led the army to garrison the Mo tribe back then, and it was also an unbreakable defense line psychologically for the soldiers and civilians in the north.

Four hundred years ago, the four kingdoms of the Central Plains were established. After nearly 100 years of peace and quiet between the four countries, they were no longer satisfied with the existing territory and resources, so the clarion call for the Great War of the Four Nations sounded.

This battle lasted for decades. The fighting between the four countries was dark, and the corpses were everywhere in sight, and the people were suffering in dire straits, and they were in pain. It wasn't until the continuous war burned out all hope that the four countries still had no tendency to swallow anyone, and seeing that the treasury was exhausted and the lives were ruined, the four countries had no choice but to give up, and signed a century-long armistice agreement with each other, and each of them waited for the right time again.

After the end of the armistice, the four countries were ostensibly peaceful, but in fact there was a turbulent undercurrent between the countries. Although there are barbarians in the north, the Western Regions in the west, the Wu tribe in the south, and the Shui Kou in the east, the borders of various countries are often harassed by these ethnic minorities, but no country dares to go to war easily, after all, the painful experience of their ancestors makes them dare not move forward rashly, for fear that once the war starts, the other three countries will take advantage of the fire to loot and reap the benefits.

When Beiming sent troops to the Mo tribe, it attracted the attention of the other three kingdoms, but due to factors such as the backward weapons and equipment of the tribal alliance, coupled with the previous confrontation with the Mo tribe for a long time, the grain and grass reserves were insufficient, and the battle would be quickly resolved, so that the other three countries had no chance to take advantage of it.

If the northern border falls at this time, Beiming will inevitably have to fight with the northern tribes, and without Xiao Yuchuan, a general, it is difficult to guarantee that the other three kingdoms will not take advantage of the situation.

Emperor Xuanwu knew that Xiao Yuchuan had been guarding the Mo clan for many years, and he had long been familiar with the geographical environment in the north, and he dared to hand over the military power at this time, and he must be completely sure that he would be able to win this battle.

Moreover, the people sent by Emperor Xuanwu to the Mo tribe were not able to find the fragment of the "Seven Killings Qin Score" in the Mo tribe, and after the Liu clan appeared, he also sent people to secretly search the residence of the Liu clan and the palace of Mo Ling, but still found nothing. This shows that the Mo clan's sheet music has been taken away, and this person is very likely to be Xiao Yuchuan who led the troops to exterminate the Mo clan.

Emperor Xuanwu immediately rejected Xiao Yuchuan's resignation, sent an edict to Xiao Yuchuan, praised the loyalty and courage of the Xiao family for generations, and the memory of Empress Renzhao, and took the opportunity to inform Xiao Yuchuan of the news that the northern tribes were about to move, and handed over the temporary command of the 20,000 garrisons in the north to Xiao Yuchuan.

Emperor Xuanwu also mentioned in the edict that the Hubu Shangshu, who has always been left and right, has reached the age of marriage with his beloved daughter, and Rong Huan is not young, it is the time to start a family, and he planned to give it to him as a concubine, and then choose a day to perform the crown prince's canonization ceremony, but Rong Huan has not yet made any merits in the court, and the Hubu Shangshu also has reservations about this matter, if he is forcibly canonized as the prince, I am afraid that he will be criticized. But if Xiao Yuchuan can hold the northern border, with the blessing of his ancestors' exploits, and then marry the daughter of the Hubu Shangshu, it will be understandable to canonize him as the crown prince in the coming year.

What Xiao Yuchuan wants is Emperor Xuanwu's words, and with Emperor Xuanwu's handwritten edict, he is not afraid that Emperor Xuanwu will cross the river and tear down the bridge again, as long as he succeeds in repelling the northern tribes, then the position of the crown prince of Rong Wei is a sure thing.

That war came quickly and ended quickly.

Although the northern tribe is good at riding and archery, and is very brave on horseback, it is still not as experienced as Xiao Yuchuan. Xiao Yuchuan has been studying the combat habits of the northern tribes for many years, and has formulated a careful combat deployment for their weaknesses - many surprise attacks, burning grass and cutting off food; The iron cavalry rushed into battle, divided and eaten, and then broke them one by one.

Soon the northern tribes were crushed, and Beiming won a great victory.

In order to calm the turmoil created by the Liu family before his death, Emperor Xuanwu weighed it again and again, and had to send Rong Sui to Beiluoshimen, away from the government and the opposition. The courtiers who still had objections to the affairs of the Mo clan back then also disappeared with the departure of Rong Sui and the good news of Xiao Yuchuan.

The following year, Rong Wei was canonized as the crown prince of Beiming, and Xiao Yuchuan took over the northern garrison and garrisoned the northern border.

Although the Xiao family's power is not as strong as it was back then, it can be regarded as rising again.

I thought that Rong Sui would leave the palace, the position of the prince would be set, and all relatives and families should also stop fighting, and there would be no need to cheat for the position of the prince. However, Rong Huan's qualifications are mediocre, and he can only rely on the merits of his grandfather's family for many years, and he still has no achievements, and he has always been gentle and generous, he really does not have half of the majesty of the prince, how can the princes and their mothers be convinced?

The battle between the princes of Beiming has intensified, and now among the nine princes, only the crown prince Rong Wei, King An Rongzhi and Ning Wang Rong are left.

The crown prince Rong Wei has a concubine, although she is not a famous lady, but she is deeply favored by the prince because of her good looks, and she is used to being arrogant and domineering on weekdays.

Last year, the crown princess was pregnant again, and the concubine entered the door for several years but her stomach did not move, and the people of the crown princess always disdained her on weekdays, so she was indignant in her heart, and she was dizzy for a while, and collided with the princess, causing the princess to slip and lose her vitality, and she could no longer have children.

The crown princess's father, Tobe Shangshu, was reluctant to marry his beloved daughter to Rong Huan, but because of the merits of Tianwei and Xiao Yuchuan, he had to make this decision. When he learned the bad news of his beloved daughter, he was filled with grief and indignation, and although the prince came to the door to plead guilty, he still went to Emperor Xuanwu unrelentingly.

This jealousy is a trivial matter, but it is a felony to harm the royal bloodline.

Emperor Xuanwu was angry and executed the concubine, and wanted to calm the turmoil, but the prince has been seen by everyone for his inaction over the years, although most of the courtiers chose to keep silent because of Xiao Yuchuan's prestige and the affection of the Hubu Shangshu, but in the end they were impeached by some ministers.

Hubu Shangshu has always been very popular in the court, and quite a reputation, as soon as this incident came out, the ministers of the court and the central government were even more golden, and the henchmen of King An and King Ning also took the opportunity to play again and again, and the prince of the palace could not even govern the back house, how to govern the country in the future?

Emperor Xuanwu could not depose the crown prince because of this matter, after all, the military power in the north and the fragment of the Seven Killings Qin score were still in the hands of Xiao Yuchuan.
