In mid-April, the Great Wall on the border of Liangzhou was in full swing, and Lu Ziji, dressed in a bloody robe, sprinted between the mountains and fields, leading black arrows to the left and stabbing again, breaking the defenses of the Uighur cavalry layer by layer.

Wait until Lu Ziji breaks through the enemy formation and retreats to the city wall in a roundabout way

At the time of the gate, the turrets on the Great Wall began to bombard, and a thunder that shook the heavens and the earth exploded into flaming flowers on the flat ground, and the ground that had long been pitted was bombarded by artillery fire again and became charred and black.

Due to the pouring of artillery fire, the pursuing Uighur cavalry was not stupid, and when they were attacked by the first wave, the whole army slowly retreated, leaving the area affected by the artillery fire.

Seeing the Uighurs retreating, Chang'an was temporarily settled, and Lu Ziji returned to the city wall, took a look at the fort, and wrote a letter non-stop and sent it to Chang'an.

A few days later, Wu Yueya received a letter from Lu Ziji from Du Fu, saying that he hoped to change the caliber of the cannon barrel and increase the firing range, so that the Hughurs would be taken by surprise.

Wu Yueya determined this matter, and began to think about increasing the range of the cannonball, but I am afraid that the process will not be able to keep up, after all, iron smelting is still that initial stage.

However, Wu Yueya also knew that in the past few months, the number of soldiers who died on the battlefield in Liangzhou was also increasing, and the Uighurs seemed to refuse to give up and insisted on fighting her, and moreover, Jiannan Mansion was too close to the Tubo people, and they didn't know if it was their conspiracy, and the two countries joined forces to besiege the Tang Dynasty.

In one morning, Wu Yueya designed the spiral cannonball and cannon barrel, drew the design drawing, and let the craftsmen of the blacksmith workshop figure it out by themselves, it was quite troublesome to make a spiral cannon barrel inside, and I don't know what method they would take to do it, but it would definitely be time-consuming and labor-intensive.

After dealing with these things, Wu Yueya and Du Fu went to inspect the city wall outside Chang'an City in the afternoon.

Outside Chang'an City, there is a layer of outer city wall, this city wall is built outside the moat, more than five zhang high, one zhang wide, Wu Yueya went up the stairs, came to the city wall, looked down on the scenery below, and occasionally there were wild birds flying overhead.

"Your Highness, in a few months, the fortifications of the city wall will be completed, with two city walls, you are not afraid of enemy attacks at all, and you can place a camp between the two city walls, which is also a lot more convenient, and more importantly, the outer city wall is much higher than the inner wall!"

Du Fu stood behind Her Royal Highness the princess and said with honor.

Wu Yueya hugged her arms and bowed her head at Du Fu, "If it weren't for the previous battle, I wouldn't have built the city wall first, and now that spring plowing is coming, let some black-armored soldiers go to farming, grow grain, and we must always be ready for war and wait for the enemy!" ”

"Yes, Your Highness, rest assured, these things Du Fu has already arranged, Chang'an, as the capital, will definitely take the lead in completing these things, and then slowly promote, put some matters in the states and counties of the Tang Dynasty on the agenda, and specially cultivate a new type of civil official, but the restructuring of these things is urgent, and it may be difficult to achieve results without seven or eight years!"

Wu Yueya thinks that what Du Fu said is right, do things gradually, the capital Chang'an as a pilot, slowly change some customs and habits and things in the court and government needs a process of change, and at present, it is still vigorously reforming the land system, so that every person can grow their own fields, support themselves, and be able to not starve or freeze in the coming year.

"Well, let's go elsewhere to see, and when the time comes, we will begin to reform the customs and systems, and at present we are still focusing on the reform of the land, by the way, I think the government can raise a herd of cattle, in the form of leasing to the people who open up the wasteland, and use it in turn, on the one hand, to solve the problem of manpower and material resources, on the other hand, it can provide convenience to the people everywhere! What do you think? Wu Yueya looked around, walked down the city wall, and walked in the direction of the barracks, and at the same time chatted with Du Fu about a plan that he had come up with temporarily.

"Your Highness, this move is indeed okay, but in terms of cattle, I'm afraid that people in the government will need to drive and feed, but at present, the fast catchers in the government and bad people from all over the country can serve at this time, I'm afraid that those assassins in the Ming Mansion will feel that it will be unseemly to act like this!" Du Fu listened to His Royal Highness's suggestion, and did not object, it is indeed okay to do so, from the documents he obtained, including their statement that the people obtained the land but could not afford to cultivate it, at that time he just showed this document to the princess, but he did not expect His Royal Highness to remember it in his heart.

"Whether it is the assassin or the Ming Mansion, as long as you refuse to cooperate with the will of the imperial court, you will be found by bad people, and you will be directly dismissed and investigated, and severely punished!" Wu Yueya thought of Jingzhou City ten years ago, and the assassin did not do much, causing the mountain bandits to act arbitrarily, and even openly confronted the government.

"Yes!"

Du Fu seemed to be a little angry when he heard it, so he directly agreed, and as for how to deal with those local officials who did not intend to cooperate with the restructuring, he planned to adopt a soft and hard approach, and gradually take back the military power in the hands of the assassin history.

Coming to the barracks, Wu Yueya saw a lot of recruits who joined the Black Armor Army, they were all busy training, and there were many sergeants who didn't seem to be suitable for the harder steel armor, after all, covering the whole body, it would inevitably cause friction, and some joints were prone to abrasions, and these new sergeants were rubbing alcohol and swelling drugs on the side.

Wu Yueya stood on the high platform, looking at the sergeants who were sweating and training in the sun, and secretly paid attention to it in her heart, and when the training of the 150,000 new troops was completed, she would personally take them to the battlefield to practice, and at the same time, she had to seize the time to open new courses, so that the veterans could tell the recruits about their experiences on the battlefield, especially the mentality when they fought against each other.

"Most of the new sergeants recruited in the spring of these things are patriots, hoping to make contributions to the frontier!" Du Fu looked at this group of new sergeants, as if he had seen the glory of the Tang Dynasty.

Wu Yueya touched her nose, then turned around and left, no longer paying attention, and at the same time gave Du Fu an order, "Remember to pull them out to farm!" ”

Du Fu was stunned for three seconds when he heard this, shook his head and laughed and hurriedly followed.

In the Martyrs' Garden, Wu Daozi is carving a stone tablet, on which the names of the Tang Dynasty saints are written, but there is no name of the Emperor of the Great Sage, and to the back of the list, it is just a simple relief of the three words 'Li Longji'.

Looking at the big stone monument of the martyr built by his own painstaking efforts, Wu Daozi was out of his body and had nothing to think about, allowing his long white hair to flutter, until his great-grandson next to him shook his arm, and then he came to his senses.

There is no saint in the eyes of the princess who protects the country, but she does rely on her own strength to defend to the death, and would rather break with the tiles than surrender to the slaves, and it is not bad to take the credit.

Wu Daozi was depressed and unhappy, but he turned around and walked away with a stubborn temper, "But this world is not her world, not her world..."
