After the negotiations, the two sides confirmed that the actual control area of the two sides should be the boundary and implement a truce and strike troops, and after the agreement was reached, the two sides would each deploy a standing army of 10,000 men within the range of 50 miles of the border, and the rest of the army must retreat beyond the range of 50 miles.

As for the duration of the truce, the agreement did not explicitly stipulate this, and both sides were somewhat tacit about this, after all, no one knew when the Hu rebellion would be quelled, and after the civil strife was quelled, there was no doubt that the agreement would lose its binding force, and the two sides could go to war at any time.

Anyway, no one takes anything on paper too seriously, and the reason why the two sides can sit down and talk can only show that both sides have demands in this regard and hope to get what they need.

After the agreement was reached, Chen Shou and Du Zhen immediately set off to return to Tongguan.

The armistice agreement was reached so quickly, and all the Shu generals were secretly surprised, but Liu Yin was unimpressed, because he knew that the current Sima Yan needed this armistice agreement more urgently than himself.

According to the agreement, Liu Yin will withdraw most of the troops in Tongguan, retain only one battalion of garrison troops in Tongguan and Wuguan, and withdraw the rest of the army to Chang'an.

Liu Yin had negotiated with Liu Chen in advance and reached a consensus on this matter, but Yongzhou Assassin Shi Yin Zheng had a different opinion on this, thinking that Liu Yin had reached a truce agreement with the Jin State in private, and was suspected of overstepping his authority.

However, Liu Yin also replied to this, now the imperial court is still in Nanzhong, thousands of miles away, even if the post road is smooth, it will take at least a few months for letters to be exchanged once, and now the battle situation on the front line is unpredictable, if everything has to be reported to the imperial court for instructions, then it will definitely delay the fighter.

What's more, Liu Yin had already written a chapter and reported to the imperial court.

Facts also proved that Liu Yin's decision was correct, just when Liu Yin had just returned to Chang'an, he received the news that the Huns Hao San and Hao Yuandu rebelled in Xiayang, Fengyi County, and the speed of the rebellion was extremely fast and wide, which was eye-popping, in just half a month, Feng Yi, Beidi, Xinping, Anding four counties were caught in the war, and the Malanqiang people, Lu Shuihu people, Di people and Hexi Xiongnu returned to the rebellion together, and the momentum was breathtaking.

The doubts about Liu Yin were immediately dispelled, and the generals in Guanzhong all praised Liu Yin's foresight, the rebellion of the Hu people in the north was fierce, if the troops could not be transferred in time to quell the rebellion, it was likely that several counties in the north would fall, and even threaten Chang'an. Liu Yin took the initiative to reach an armistice agreement with the Jin State and withdraw the main force from the Tongguan front, which now seems to be undoubtedly the wisest choice.

At this moment, the Jin army obviously can't wait to complete the withdrawal, and most of Yanghu's army will be transferred to Nanyang to form an offensive against the Zhonghui rebels in Xiangyang. Du Pre's army withdrew from Wuguan, crossed the Yellow River north, and entered Bingzhou to quell the rebellion of the Hun Liu Yuan.

Sima Yan felt a sense of relief that the problem of insufficient troops that had plagued him for many days had finally been resolved, and he believed that as long as the army arrived, whether it was Zhonghui's rebellion or Liu Yuan's rebellion, it would be put down in a short time.

However, Sima Yan's prediction of the situation is obviously too optimistic, for the Hu people, Sima Yan may never really look down on it, even if Liu Yuan killed Hu Fen, even if he unified the five Xiongnu departments, in Sima Yan's eyes, these barbarians are still difficult to achieve big things, so Sima Yan is not too concerned about the rebellion of the Xiongnu, and even does not pay enough attention to it, and the main force led by Yanghu will go to deal with Zhonghui, and Du Yu's partial division will go north to deal with Liu Yuan.

But what Sima Yan didn't expect was that the storm caused by Liu Yuan's rebellion swept the entire northern states in a very short period of time, in Bingzhou was the rebellion of the Huns, in Shangdang was the rebellion of the Qian, in Jizhou was the rebellion of the Di people, and in Youzhou was the rebellion of the Xianbei people.

The war did not spread to the Hedong region, and the Hexi region controlled by the Shu army was not spared.

In addition to the Liu Bao branch of the Xiongnu who moved south to the state, there was another branch left in the north area west of the Yellow River, in the south of the Hetao, west of the state, and north of Guanzhong, in addition to the Xiongnu, Qiang, Zhuhu side by side, the ethnic composition is the most complex, this area was once the jurisdiction of Shuofang County of the Han Dynasty, but after entering the Three Kingdoms era, Cao Wei's influence on this land gradually declined, and the rise of the Xiongnu, Malanqiang, Lushuihu and Di people, Let this land truly become a place of chaos.

These Hu people, not satisfied with the survival of this land, they often roar south, harassing Guanzhong, burning, killing and looting, raping and plundering, for the harm of one party, Cao Wei's garrison in Guanzhong is limited, and the nuisance of the northern Hu seems powerless, for a long time, these Hu people are wanton and unscrupulous in Guanzhong.

At this moment, Liu Yuan's rebellion in Bingzhou greatly stimulated the northern Hu, so the two brothers Hao San and Hao Yuandu of the Northern Xiongnu took the lead in raising troops in Xiayang, and soon the Qi Wannian Division, the Ma Lanqiang people, and the Lu Shuihu people also rose up one after another, and the wave of rebellion soon swept the four counties of the northern land.

Compared with the merger of Liu Yuan, the Beidi Hu is much more chaotic, the Hu are fighting for each other, not subordinate to each other, only because other Hu troops rebelled, they are not far behind, but also raised troops to rebel, in order to fight for territory, it is not a new thing for the Hu to fight between them, but so many forces are superimposed together, or the situation in Guanzhong has a great impact.

At this moment, Liu Yin has returned to Chang'an, and the rebellion of Beidi Hu did not surprise him at all, in order to stabilize the overall situation of Guanzhong, he must strike hard at Beidi Hu.

Liu Yin left Fu Yan's left army to guard Chang'an, while taking into account the direction of Tongguan and Wuguan, although he had a truce agreement with the Jin State, Liu Yin did not dare to engage too much, after all, at a critical time, it was just a piece of waste paper. Then he personally led the Central Army to cross Weishui to the north, and joined up with the Right Army Corps, which had been stationed in Weibei earlier, to prepare for the march.
