The Wei court immediately began to operate efficiently, first of all, the heralds with the order of King Qin came out in all directions, galloping in all directions at an accelerated speed of eight hundred miles. Of course, it still takes a lot of thought for them to get out of the city and break out of the encirclement of the Shu army.

Zhong Xuan organized a breakout battle, let 3,000 soldiers kill from the east gate, and attack the Shu army stationed outside the east gate, and those heralds were mixed in the 3,000 soldiers and horses, taking advantage of the chaos.

The soldiers sent by Zhang Bao to each of the other city gates numbered about 500 people, all of whom were Xianbei people. They have poor discipline and usually perform loosely, but as a cavalry unit, they are never afraid of confronting the foot soldiers head-on, and as nomads, their temperament is also more fierce and impulsive, so even if they see that the Wei army has 3,000 people, these Xianbei cavalry do not hesitate to rush up to fight.

As a result, the two sides suffered mutual damage after a scuffle, and of course, the number of casualties of the Wei army was several times that of the Xianbei cavalry, which was the result of the restraint of the troops. After two quarters of an hour of fighting, each Ming Jin withdrew his troops, and the three thousand Wei troops retreated into Chang'an City, but the Wei cavalry who delivered the letter had already taken advantage of the fact that the Xianbei cavalry was entangled and ran away.

The messenger was successfully delivered, and all that remained was to hold on for a certain amount of time and wait for help. The entire city of Chang'an was mobilized, all the soldiers canceled their vacations, the horses did not unload their saddles, the people did not unarmour, and they were on call for twelve hours.

Of course, the soldiers will still take shifts to guard the city wall, after all, people are not iron, they all need to rest, so the Wei army also worked in three shifts, one shift was on duty, and the other two shifts were resting, so that the soldiers could conserve their physical strength.

However, no one is allowed to leave the barracks without permission when they are on duty, and even in the barracks, they need to be vigilant at all times and be ready to go to battle at any time. This is also a characteristic of wartime, once the enemy is in a hurry to attack the city, the battle is tight, and a group of people can not withstand the enemy's attack, these soldiers who are resting in shifts will be urgently sent to the battlefield.

In addition to the nerves of the soldiers, the people were not having a good time. The young and strong people in the city were mobilized, and those with better physical fitness were temporarily conscripted into the army as reserve soldiers.

This allowed Cao Pi to gain tens of thousands of more soldiers, and there were as many as 200,000 soldiers in the entire Chang'an City. Of course, these tens of thousands of recruits cannot be called qualified soldiers, and they still need a lot of training before they can be of great use, and now they can only step up their training while helping the regular army do some auxiliary work.

And the leftover young men could not be idle, and as people's husbands, they carried various siege materials such as wooden rolling stones for the defending troops. Those skilled craftsmen were gathered to make bows, arrows, stone throwers and other weapons and instruments.

The young and strong people in the family were recruited, and the women of the family and other old and sick people naturally became sad. After all, Qingzhuang is the pillar of the family, and they usually do a lot of heavy work and tiring work, but now that they are not at home, these heavy and tiring jobs are pressed on others.

Not only did the family have to do more work, but some women were also drafted to be responsible for sewing military uniforms, military shoes, flags and other military supplies. It can be said that now the entire Chang'an City has become a large military camp, and almost all production and activities revolve around military purposes, which is a bit of a sense that all the people are soldiers.

There is no way, the enemy has already hit the door, and the Wei State has reached the moment of life and death, and if you don't fight hard at this time, you will lose the country. There can be several beats in life, this sentence is also applicable to a country, and if you don't fight now, you really don't have to fight in the future.

After all, Cao Wei's court is relatively clear, after all, Cao Cao, a talented and eloquent hero, has been working hard for so many years, and now it has just been handed over to the loser Cao Pi not long ago, and he has not yet handed over Cao Cao's family to him.

With these family backgrounds, the entire imperial court is operating very well, and the mobilization work of the whole city has been done very well this time, and when this soldier is approaching the city, there is no chaos in the city, which is commendable.

Cao Pi and a cadre of ministers in the city did not have a good life, and Zhang Bao, who was stationed outside the city, did not have a very comfortable life. His troubles mainly came from Cao Hong, this guy went to the Shuai tent several times a day to find Zhang Bao, wanting him to send troops to attack the city as soon as possible, so as to rescue his family as soon as possible.

Zhang Bao persuaded him and comforted him that his family had been notified and hidden by himself early in the morning, and Cao Pi would not be able to find them in the short term, so he would be fine, please rest assured.

But Cao Hong can't let go of his heart, although he loves money, he also cares about his family, so no matter how Zhang Bao persuades, he still comes to nag Zhang Bao several times a day.

Zhang Bao naturally ignored him, the army's operational strategy had already been set by the General Staff Headquarters before it set off, and now it was just that the division staff headquarters was implementing the plan according to the plan of the General Staff Headquarters, where would he disrupt the established plan drawn up by the old foxes of the General Staff because of these "little things" of Cao Hong.

Therefore, Zhang Bao comforted Cao Hong with kind words every time, but when he turned around, he was not moved at all. After the Shu army came to the outside of Chang'an, they were not in a hurry to attack the city at all, but chose a suitable place to set up camp, build fortifications in some strategic places, set up ambush circles, create blocking positions or defensive positions, etc., and were very busy.

Three days later, the first reinforcements of Wei arrived, and this first batch of reinforcements came from Tongguan, that is, the Eastern Front.

This route passes through the more economically developed areas, and the roads are relatively well built, so they come quickly. This group of 30,000 men came from the third line of defense on the Eastern Front.

Cao Pi set up layers of defense lines on the Eastern Front, which can be roughly divided into three levels, that is, the outer, middle, and inner lines. The first is centered on the Tiger Prison Pass, the second is dominated by the Hangu Pass, and the last is established by relying on the Tongguan Pass.

Of course, these three lines of defense are just a concept, and each line of defense is not just a big checkpoint, but in front of and behind these three world-famous Daguan cities, dense small checkpoints, walled forts, etc., are also arranged to build a three-dimensional defense system.

It can be said that the long road from Tiger Pass to Chang'an was full of Wei army fortifications. The Shu army wants to kill from the eastern front, along the way~ will face countless ambushes, interceptions, and blockades, and along the way to pull out ~ countless checkpoints, military villages, fortresses, etc., which can be described as dangerous step by step.

This is the "Maginot Line" of Wei, if it is killed by other cold weapon troops, there will definitely be a feeling of frightening step by step, and it is difficult to move an inch, and I don't know how many lives will be lost along the way, even if there are enough lives to fill in, this battle is estimated to be fought for a year and a half.

Among the Wei troops on the Eastern Front, the inner defenders of Tongguan were closest to Chang'an, so they came the fastest. Moreover, the Shu army was still refused to be in the east of the Tiger Prison Pass, and it was still far from here, so they could safely dispatch most of their troops to aid Chang'an.
