Although Shu Han has firmly established a firm foothold in Guanzhong, but from the perspective of the situation, it is still in the east and west of the Jin State, Liangzhou west of Yongzhou, in addition to Jincheng County in the hands of Shu Han, Xiping County belongs to the Qiang people, Liangzhou's four counties in Hexi, still in the hands of Cao Wei, which somewhat makes Liu Yin's Yongliang Governor a little unworthy of the name.

Guanzhong is now facing the enemy on three sides, needless to say in the east, there are Xiongnu, Di, Xianbei Zhuhu tribes in the north, among which the Xiongnu are the most powerful, known as "Beidi Hu", the distance is in the south of the Hetao, the area north of Feng Yi is stable, there are sometimes southward nuisance and plunder, which poses a considerable threat to the Guanzhong area. This is also the main reason why Liu Yin has always placed the strength of an army near Chang'an, and the main purpose is to prevent Beidihu.

Although the four counties of Hexi did not have much strength in the Jin Kingdom (the combined strength of the four counties was only about 20,000 people), Liangzhou Weike always made Liu Yin like a stalk in the throat, saying that it was impossible to allow others to snore next to the couch, and now the relationship between Guanzhong and Liangzhou is about the same.

In view of the current situation in Guanzhong, although Liu Yinchan was quite moved to move the capital to Chang'an, he was also worried and could not make up his mind. Although Nanzhong is located in the middle of nowhere, but in terms of security alone, there is probably no place in the world that is safer than there, and the queen Liu Chan is not the kind of king who is ambitious and enterprising, where the capital is located, the first consideration is the safety of the capital, so the move of the capital has not been fruitful.

After returning to Chang'an, Liu Yin's first consideration was the strategy of defending the north in the east and refusing to advance westward, and in the treatment of Sima Yan in the east, Liu Yin still insisted on sticking to the dangerous passes, and Liu Yin had no good way to do it for the time being, so he could only build an effective defense line in the three counties of Fengyi, Beidi and Anding north of Chang'an. In order to block its southward movement, at the same time, the left army of Lu Hong was transferred back to Chang'an, and the garrison near Chang'an was strengthened, so as to meet the needs of the emergency.

For the four counties of Hexi in Liangzhou, Liu Yin is ready to attack strongly and completely solve this worry.

The Liangzhou Thorn History Department of the Jin State was located in Guzang in Wuwei County. The current Liangzhou Thorn History is Xu Wu, the son of Xu Miao, the former Liangzhou Thorn History, Xu Miao during his tenure as the Liangzhou Thorn History, in the northwest to build water conservancy, open up paddy fields, and raise poor people to rent it, resulting in the overflow of the warehouse. At the same time, we should change customs and rectify the rule of officials. To all Hu Qiang, Rong and envy, they are willing to pay tribute to Cao Wei. It is a state border and a smooth flow in the Western Regions.

But since Liu Yin captured Guanlong. Completely cut off the connection between Liangzhou and Luoyang, especially after Liu Yin captured Jincheng and Xiping, the four counties of Hexi were almost reduced to an isolated state, due to the news blockage, Sima Yan called the emperor in Luoyang After the establishment of the Jin Dynasty, Liangzhou was still hung with Cao Wei's banner within a few months, and he didn't know that Cao Wei's sky had changed. Sima Yan's latest appointment was not delivered to the four counties of Hexi until very late. The change of flag in Liangzhou was not completed until the spring of the second year of Thailand.

Since Liu Yin has decided to capture the four counties of Xiliang, he has been formulating this plan since he entered Yanxing for four years.

If you look at it purely from the comparison of troops, it seems that there is no difficulty in taking Liangzhou, after all, the average strength of each of the four counties in Hexi is only 5,000 people. The Hexi Corridor is a long and narrow flat land, starting from Wusheling in the east and reaching Yumen Pass in the west, the narrowest place is only a few miles away, and the wide place is two or three hundred miles. As for the length, it is about 2,000 li, and if you spread 20,000 horses into an area of 2,000 li, no one will think how difficult it will be to go west.

But Liu Yin is cautious, he knows that fighting a war is by no means a factor of comparison of troops, the most difficult thing about the westward expedition to Liangzhou is the climate and geographical advantages, and these two factors will be the key conditions for the westward expansion, just imagine that the army of Shu Han marched on the desert Gobi, the most difficult thing is not to encounter the enemy, but to encounter strong winds, sandstorms, drought, climate and geography will be the most important part of the success or failure of the westward expedition.

Planning and then acting is Liu Yin's consistent strategy, and not fighting an unprepared battle is also Liu Yin's creed. For this reason, Liu Yin has held several meetings to discuss the route and strategy of the march, and has also had many exchanges with Deng Ai, and listened carefully to Deng Ai's opinions. Yongliang's old generals such as Lianhong and Wang Ji also provided Liu Yin with many constructive suggestions and suggestions for Liu Yin to improve the plan.

Just when Liu Yin was preparing to march into Liangzhou, Yao Yikang, who was stationed in Huayin, suddenly ran to Chang'an to meet Liu Yin.

In this western expedition, Liu Yin will definitely mobilize Yao Yikang's Qiang cavalry, even if the 30,000 people are not all used, at least about half of the Qiang cavalry will be used. Of course, before completing the final preparations, Liu Yin did not inform Yao Yikang, and at this moment Yao Yikang suddenly ran over, which made Liu Yin a little surprised.

After all, the Qiang cavalry is an independent army, not the six armies under Liu Yin, even if Liu Yin is ready to use troops, he must discuss it with Yao Yikang.

"Quick pass!" Liu Yin heard the news that Yao Yikang wanted to see him, and immediately ordered him to see him.

Yao Yikang walked like the wind and came up quickly, but he staggered, and before Liu Yin could speak, Yao Yikang had already knelt in front of Liu Yin, and said silently: "Big brother, you have to avenge your little brother!" ”

Liu Yin was taken aback, and hurriedly helped Yao Yikang up, confused, and asked, "Brother Xian, why did you take revenge?" ”

Yao Yikang's cry, although Liu Yin didn't know what was going on, he instinctively thought that he was angry with others, but the Qiang cavalry was stationed in Huayin, and there was no intersection with the local government and the surrounding Shu army, the Qiang cavalry was different from Liu Yin's own army, and the military discipline should be free and loose, but they were guest troops, and the military regulations of the Shu army were not suitable for them, so there were some things, Liu Yin would turn a blind eye, even if the Qiang cavalry had some nuisance to harass the people, as long as it was not too excessive, Liu Yin ordered to go down, Not to be pursued.

Thinking about coming to Huayin, only Yao Yikang bullies others, when will it be the turn of others to bully him, and now as soon as he enters the door, he keeps asking Liu Yin to avenge him, and he is crying so much, as uncomfortable as his dead father, which makes Liu Yin feel inexplicable.

Yao Yikang cried so much that he couldn't say anything when he opened his mouth several times, just whimpering and looking sad.

"Brother Xian, don't worry, say it slowly, the big thing, the foolish brother will also make the decision for you." Liu Yin comforted.

Yao Yikang cried and said, "Big brother...... I...... My Father...... He...... He was killed......" (To be continued.) )
