The spring in Longxi comes exceptionally fast, the ice and snow have just melted, and the willows have already spit out the tender buds, and the fields are full of green, full of vitality.

It was supposed to be the season of spring ploughing, but the fields were full of weeds that had just submerged into the horse's hooves, there were no farmers ploughing, and there were no traces of pedestrians on the roads.

This qiē is Sima Yi's "masterpiece". After Liu Ze retired last winter, Cao Cao also left Longxi, and the squad returned to Xudu. Sima Yi was promoted to the governor of Yongzhou because of his outstanding performance in the Battle of Longxi, and he was promoted from a prime minister's mansion lord Bo Yiyue to the governor of Yongzhou, the general of Zhenxi, and the military governor of Longxi, and became a feudal official.

Cao Cao's appointment, almost all of them were surprised, Sima Yi did not have time to stand, although he was born in a prestigious family, he was not very interested in the official career, and he has not been sick, and he was forcibly recruited by Cao Cao two years ago as the prime minister's mansion, and has been serving in the army as a staff member, and has never had the experience of leading troops to fight.

Although many people advised Cao Cao to carefully consider the candidate for the governor of Longxi, Cao Cao insisted on his own opinion, left Sima Yi with an army of 150,000, made Guo Huai the deputy governor, assisted Sima Yi in guarding Longxi, and made Cao Hong the governor of Guanzhong and the general of Zhengxi, Hao Zhao and Wang Shuang as deputies, led 100,000 troops to guard Chang'an, and Cao Cao's army returned to Xudu.

The reason why Cao Cao was able to impress was Sima Yi's "Guanlong Garrison Long Strategy", in which Sima Yi proposed that Liu Ze tried to enter Guanzhong north, and he must first take Longshang and Longyou's defense. is the key to the top priority. The terrain of Longyou is flat, Liu Ze has a strong cavalry, and he can not match it at all in the field battle, so he can only rely on the deep trenches and high bases of the fortified city to resist, and establish Shangqi, Linwei, Wucheng, and Lintao as the first line, and Jixian, Longxi, and Nan'an as the second line. Jincheng and Beidi are the great defensive depth of the third line, and the people of the first and second lines are moved to the third line, and the strong walls south of Shangtai and Ji counties are cleared, leaving not a single person or a single millet behind. The Shu Road is difficult and dangerous, the grain and grass are difficult to transport, and the logistics supply is Liu Ze's biggest shortcoming, so Liu Ze must seek a quick victory when he dispatches troops to Longyou. As long as the Wei army adheres to its own defense policy, resists the enemy with high bases and deep trenches, and the territory of Longyou will definitely be as stable as a mountain.

Cao Cao admired Sima Yi's strategy very much, and in Guanlong, Cao Cao did not seek to occupy much strategic advantage, but could only defend it, and Cao Cao was satisfied. From Guanlong to Bashu, this road is too difficult. As long as he sits firmly in Guanlong, Cao Cao can concentrate on using troops in Jingxiang Jianghuai, after all, in Cao Cao's strategic concept, this is the main direction of attack.

Sima Yi sat behind Longxi. Immediately, he began to implement an iron-fisted policy, forcibly relocating the people south of Shangtai and Jicheng to the area of Beidi County in Jincheng County. The people of Longxi have lived here for generations, and they are naturally unwilling to leave their hometowns, crying on the road, crying and grabbing the land. But the tiger-like Cao soldiers forcibly drove them away, robbed them of their food, burned down their houses, and ordered the people to move their families in the ice and snow, and those who did not obey were all killed.

But Sima Yi is like a stone, a scholar, and the brutal methods he showed were more cruel than the barbaric butchers, which made all the subordinates in Yongzhou tremble. Tianshui guarded Yang Fujian yì Sima Yi waited until the spring season to emigrate, but Sima Yi ignored it, because he understood that Liu Ze would not give him time to do the kind things of a woman, so he had to turn the entire Longnan region into a no-man's land before spring arrived.

Bloody and iron-fisted, Sima Yi's prestige in Longxi is rising, and no one dares to hold his edge. At the same time as emigrating, Sima Yi requisitioned hundreds of thousands of soldiers and civilians, rushed to repair the city defenses of Shangqi and Jicheng, and was ready to meet Liu Ze.

In the spring and March of the thirteenth year of Jian'an, 200,000 soldiers from the four corps of the Jing Army left Qishan and began the second Northern Expedition.

Compared with the sloppiness and haste in the first Northern Expedition, Liu Ze carefully prepared and deployed the troops this time, and one million Hu grains were continuously transported from Wuchang Xiangyang to Nanzheng along the Han River. On the sloping valley road from Nanzheng to Qishan, it is the wooden oxen and flowing horses invented by Zhuge Liang who are transporting military grain, and the soldiers and horses are not moving, and the grain and grass go first. After a winter's rest, the morale of the army was high, full of spirit, and high morale, Liu Ze chose to send troops at this time, which was the right time.

Liu Ze set up a village in Qishan, convened the governors of all walks of life to discuss the big tent, and discussed the plan to march into the army. Zhao Yun, the governor of the First Legion, Xu Rong, the deputy governor, Huang Zhong, the deputy governor Wei Yan, and Yin Guan, the governor of the Eighth Army, Yan Yan, the deputy governor of the Ninth Army, Zhang Ren, and Fa Zheng, the governor of the Tenth Army, Ma Chao, the deputy governor, Pang De, and Yan Pu, the commander of the army, all gathered in the Chinese military tent and waited for the dispatch. Only Jia Xu, who joined the First Army, was seriously ill and recuperated in Chengdu, but never went to the Qishan front. Liu Ze sat in the main seat, and the military advisor Zhuge Liang accompanied him in the side position.

Ma Chao took the initiative to ask Ying to fight, Longxi is Ma Chao's sad place, if he falls there, he will get up there, the arrogant Ma Chao does not have the intention of slumping, and when he returns to Longxi, he just wants to prove his worth.

Of course, he is not the only one who wants to compete for the first credit, as soon as Ma Chao finished speaking, Zhao Yun, Huang Zhong, and Yan Yan rushed to ask for their lives to fight, representing their own legions to build this first achievement.

Everyone understands the shape of Longxi very well, Sima Yi was a scholar, and he was entrusted with a heavy task by Cao Cao, which seems to be a joke, not to mention that this time the Jing army with 200,000 troops against Sima Yi's 150,000 army, the advantage is still quite obvious.

Liu Ze is not so easy, he also thinks that Sima Yi is not easy to deal with Zhuge Liang, a scholar who has no power to restrain his chicken, can do such a vicious and tragic thing, this person is definitely not simple, "Sima Yi has the heart of a tiger and a wolf", this is Zhuge Liang's comment to Sima Yi.

Sima Yi created a hundred miles of uninhabited land in Longnan, and the walls were clear, just to make the Jing army unable to get supplies, grain and grass, unable to fight, unable to defend, and obediently retreated to Hanzhong. Although Liu Ze disdained Sima Yi's approach, he also had to admit that Sima Yi's hand was ruthless enough, and it was completely the rhythm of forcing the Jing army to a dead end.

Now Sima Yi has established three lines of defense in the Longxi area, personally led a large army to be stationed in Shangqi, built Shangqi as solid as gold, and centered on Shangqi, and divided troops to garrison Jicheng, Linwei, Wucheng, Lintao, Nan'an and other places, forming a large strategic defense depth zone, relying on each other, each other is the inside and outside, if you want to take Longxi lightly, it is almost impossible.

However, in the face of the generals' enthusiasm for the war, Liu Ze did not pour cold water on his face, so he ordered Ma Chao to take Wucheng, Huang Zhong to take Linwei, Zhao Yun to attack Shangqi, Yan Yan led his troops to Sanguan to block Cao Hong's Guanzhong army that could be reinforced to the west.

As expected, Sima Yi started to shrink his head as a turtle, and let the Jing army insult him in every way, and he didn't go to war to live or die, and the Jing army came to attack the city in a hurry, but it was in Sima Yi's arms, and the sufficient defensive preparations made the Jing army who came to attack the city suffer. Sima Yi didn't rest this winter, not only strengthened the city defenses, but also prepared a large number of bows, crossbows, arrows, horse and deer antlers, and even a lot of fine sand and water.

Sima Yi carefully studied the siege tactics of the Jing army, and the battle of Yangping Pass left a deep impression on him, the reason why the Jing army was able to conquer the steep Yangping Pass was to rely on firearms, once the city was covered by fire, all efforts were in vain. In response to the firearms attack of the Jing army, Sima Yi was ingenious and prepared a large amount of fine sand and soil and clear water, and once a firearm hit a certain place in the city, a fire extinguishing team immediately rushed to extinguish the fire to prevent the fire from spreading.

After attacking for more than ten days in a row, the cities of Shangtai were really hard to bite, and the Jing army was frustrated and demoralized. (To be continued......)
