The army attacked, and the situation in the entire Guanzhong suddenly became tense, and Liu Yin's main force did not return to the west, and the burden of defense on the eastern front was pressed on Fu Yan, Huang Chong and Wang Ji.

At present, the strength of the Shu army in Guanzhong is only 15,000 people in the three battalions of Fu Yan's front army stationed in Tongguan, 10,000 people in the two battalions of the left army stationed in Pubanjin and Huang Chong, 10,000 people in the two battalions of Wang Ji's rear army stationed in Wuguan, and 10,000 people in the two battalions of the right army of Xianhong stationed in Chang'an, the total strength is only 45,000 people.

With less than 50,000 troops and the Jin 200,000 army to compete, no one thought that this would be an easy battle, because the Jin army was a three-way attack, Tongguan, Wuguan, Pubanjin three key passes at the same time, so that the defensive pressure of the Shu army increased greatly.

In the first two years, when Du pre-attacked Wuguan, the Wei army was single-handed, although Du pre-broke through Wuguan, and even hit Lantian in Guanzhong, but the pressure on Guanzhong was never great, and then Liu Yin sent troops to Shangyong, but easily resolved the crisis that time.

But this time it was different, Sima Yan requisitioned 200,000 troops, accounting for almost forty percent of the total domestic strength (due to the wars over the years, the army of Wei and Jin was quite seriously damaged, and the 180,000 army when Zhonghui entered Shu was only 11 or 20,000 people left, and Sima Wang's army in Guanzhong was heavily damaged when he was defeated, and the army was damaged by more than 100,000 people, and the southern front battle was also a lot of casualties, although some soldiers were added in the follow-up, but overall, the army of the Jin State is currently only maintained at about 500,000, which is still a lot worse than the more than 600,000 people in the heyday of Cao Wei). Since at least more than 100,000 troops had to be maintained on the front line of Jingzhou in Huainan, it could be seen that Sima Yan mobilized almost all the forces that could be mobilized in order to recapture Guanzhong.

For Sima Yan, this is undoubtedly a gamble, if you win, you can recapture Guanzhong, and if you lose, the consequences are unimaginable.

The first to attack was the Zhennan General South Road Governor Du Pre, Du Pre's army, originally stationed in the area of Xiangyang Nanyang, after receiving Sima Yan's order, first launched an attack on Wuguan.

This is the second time Du Pre has attacked Wuguan, but his opponent has been replaced by Wang Ji from Zhan Hong, but this is obviously not too different, Wang Ji and Zhan Hong are Cao Wei's generals, one was Tianshui Taishou before, and the other was Longxi Taishou, whether it is ability or level, almost comparable, the same is still a five-to-one comparison of troops, Du Pre Wuguan is familiar with the road and full of confidence.

However, the situation at this time is obviously not the same as when Zhao Hong guarded Wuguan, when Zhao Hong rushed to Wuguan, Du Pre led his troops to advance thousands of miles, and also killed under the city of Wuguan, the two sides fought an encounter, Wuguan was broken, there was not much city defense to rely on, and Du Pre occupied the advantage of troops, so he quickly broke through the defense line of the Shu army.

The Shu army has been based in Wuguan for several years, after full repair, Wuguan has been restored to the old appearance of the Qin State, when Du Pre came to attack again, a Xiongguan was already in front of him.

Since Wuguan has been completed, there is no point in garrisoning the Suspension Bridge Ridge in front of Wuguan, and when Du Pre led the army to the Suspension Bridge Ridge, it was empty, which couldn't help but make Du Pre feel a lot. When he attacked Wuguan for the first time, he broke out a life-and-death battle with Zhan Hong in Suspension Bridge Ridge, and Zhan Hong defended it with danger, and the Wei army could not open the situation.

And now that people go to Lingkong, the empty mountains are lonely, which makes Du Fusheng sigh.

"General Du, the vanguard battalion has arrived at the city of Wuguan, and the city will be attacked without a camp, the Shu army is stubborn, our army cannot be attacked, and the two sides are still in a stalemate." Deputy General Shao Yuan reported to Du on the battle situation ahead.

Du Yu nodded, indicating that he knew, if it was just an attack by a forward battalion to win Wuguan, then Wuguan, which was known as one of the four stops of Qin Pass, would become a joke.

Wuguan Guancheng is built on a relatively flat plateau between the canyons, the north is dependent on the lofty Shaoxi Mountain, the south is endangered, the mountains are surrounded by water, and the danger is natural. Wang Ji took over the defense of Zhan Hong, and on the basis of Zhan Hong's repair of Wuguan, he continued to increase the intensity of repair, and the wall alone was fully raised by three feet. Don't underestimate these three feet, the so-called hundred feet, it is very difficult to go further, the towering city wall is three feet higher, for the siege troops, the degree of difficulty is not just three feet.

Wang Ji not only heightened and strengthened the city wall, but also made sufficient preparations for defensive weapons, such as bows, crossbows, arrows, rolling wood, stones, and boiling water. Different from Zhan Hong's good courage and good fighting, Wang Ji is known for being good at guarding, Wang Ji has a calm personality and is expected to be thorough, Liu Yin will switch him and Zhan Hong, it is for this consideration.

After Wang Ji arrived, he knew that the responsibility was heavy, and he did not dare to slack off in the slightest, and moved the defensive line forward to the Suspension Bridge Ridge like Zhao Hong's risky move, Wang Ji categorically would not do it, and he put his main energy on the repair and preparation of Wuguan, through Wang Ji's efforts, Wuguan is at least as solid as a rock, even if it is not impregnable.

The defenders of Wuguan can only maintain about 10,000 people at most, and the weakness of the force makes Wang Ji realize that only by increasing the defensive strength of Wuguan and relying on the dangerous passes, it is possible to hold Wuguan.

When the vanguard battalion of the Jin army killed under the city of Wuguan, not to mention the village, even the heel has not yet stood firm, and launched an attack on the city wall of Wuguan, due to the narrow mountain road, large siege equipment such as catapults and siege vehicles can not be transported to the city of Wuguan, the only thing that the Jin army can take is to rely on the tactics of the sea of people, launch an ant attack, and use continuous attacks to destroy the will of the defenders.

However, they obviously underestimated the determination of the Shu army to defend the city, and tried in vain to disrupt the rhythm of the defenders with a surprise attack, but the rain of arrows on the city seemed to show the determination of the Shu army, and Wuguan would definitely not be a bone that could be easily gnawed.

When Du Pre arrived at Wuguan City, the pioneer battalion was already suffering heavy casualties and heavy losses, and originally wanted to take Wuguan in one go, but was hit by a blow to the head, Du Pre had to order Mingjin to withdraw his troops, temporarily set up camp, and fight again tomorrow.
