The entire Tang Dynasty was a drunkard, but Merton didn't care about the mess he caused at all, but came to the outside of Chang'an City, staring directly at the west, according to the letter, today is the day of the return of the firearms superintendent.

There was a lot of traffic on the brick road, but there was still no firearms supervisor, but Merton did not have the slightest anxiety, but continued to wait.

Slowly, there was a commotion on the official road, and then it quickly turned into a burst of exclamations, only to see a long convoy of dusty returns, and even on the carriages, you can clearly see the traces left by swords, bows and crossbows, and there are many black marks left by gunpowder.

Combined with these, it is not difficult to guess that this team officially became famous in the first battle of the firearms supervision team.

"See the sacrificial wine!"

Seeing Merton waiting outside Chang'an City, the eyes of the firearms supervisors showed fanaticism, and they dismounted and bowed down in unison, and it was the sacrificial wine in front of them that led them to create one miracle after another, so that the firearms supervisors had supreme honor.

"Ladies and gentlemen, I waited for my triumphant return and finally arrived in Chang'an City." Merton looked at the troops who were following him in the north and south, and couldn't help but shout.

Suddenly, there were bursts of proud shouts from the firearms superintendents, and this battle was well deserved by the firearms superintendents to call it triumphant.

"However, now is not the time for you to return to the mountain, Your Majesty heard about the achievements of your and others, and is ready to personally see the firearms supervision drill in the Xishan military camp, and now this sacrificial wine has ordered, you and others will immediately return to the camp to replenish firearms and accept the review of Your Majesty!" Merton commanded proudly.

"Your Majesty's review?" Suddenly, all the firearms supervisors couldn't help but breathe, they didn't expect that they would be able to have this honor.

"Obey!"

The firearms supervisor suddenly had a high morale and said proudly.

Soon, the firearms supervisor immediately rushed back to the arsenal and replenished all the depleted firearms, and in an instant, the firearms supervisor was resurrected with full blood, and the murderous aura was awe-inspiring.

West Hill Camp.

When Li Shimin led the civil and military ministers to see the firearms supervisor, he couldn't help but shrink his eyes, the firearms supervisor who had experienced the baptism of iron and fire had completed the transformation and became a real elite division.

"Your Majesty, the firearms supervisor has a thousand soldiers in the army, and there are 820 people, please review it." Merton said proudly.

"1,000, 820." The military general instantly understood this, and couldn't help but darken his face, and the remaining one hundred and eighty people were naturally already damaged in battle.

The civil officials also quickly understood what Morton meant, and at the same time they couldn't help but smack their tongues at the combat power of the firearms supervisor, you must know that the firearms supervisor did not lose a single person in the western expedition to Gaochang, even if he defeated 5,000 Tibetan cavalry, in the end it was only 180 people lost in the battle, and this combat power could not help but make the civil officials' hearts palpitate.

Li Shimin couldn't help but be solemn, and couldn't help but feel a little more solemn in the face of the firearms supervisor.

"Let's get started!" Li Shimin ordered.

"Yes!" Merton bowed down to receive the order! With a wave of his big hand, a rapid whistle sounded in the firearms supervision phalanx, which was the sound of the alarm of the firearms supervisor in distress.

Almost at the same time, the convoy of the firearms superintendent began to move, dozens of carriages tightly encircled an inner formation, and more than a hundred horse-drawn carriages tightly enclosed an outer formation, and it only took a stick of incense to complete all this.

"What does that mean?" Li Shimin said strangely.

Li Shimin and others stood on the review stand, holding binoculars to see the firearms superintendent's array clearly, only to see that the inner array of the firearms superintendent was circular, while the outer array was like a hedgehog, and the two carriages protruded from the top one after another, and the sharp corners were uneven, like a prism.

Merton explained: "This is the most powerful formation of the Stick - the Prism, once the Prism is formed, no matter where the enemy attacks the Prism, the enemy will be exposed to another Prism, an enemy will face two or three soldiers attack, the Firearms Supervisor can form a cross attack, once the enemy breaks through to the front of the formation, the pressure will be doubled, greatly enhancing the defense." ”

Li Shimin's heart was shocked, he has been good at fighting for a long time, and naturally knows that once he is attacked from the left and right, on the huge battlefield, I am afraid that no matter how strong the force is, he will be attacked by the enemy, and the Mo family has formed such a fierce formation just by using a carriage, which is indeed extraordinary.

The eyes of many generals flashed slightly, and now most of the major cities in the Tang Dynasty are straight city walls, coupled with the protection of the moat, with a little transformation, the city wall will be transformed into a prismatic array, and the defensive power will definitely be doubled.

"What a pity! Pity! Such a peerless fierce array was born at the wrong time, if it was born a hundred years earlier, it would definitely be famous, but unfortunately now in front of gunpowder, it can be broken in a powerful castle with one blow, and the prismatic array can be said to be born at the wrong time! A civil official suddenly sighed.

The ministers couldn't help but sigh in their hearts, a blow of gunpowder broke the city not only shocked the Western Regions, but also shocked the Tang Dynasty, if you want to talk about the city wall the most, there is no doubt that the Tang Dynasty has created the strongest spear, making the status of the strongest shield city wall of the Tang Dynasty embarrassing.

"Definitely! The appearance of gunpowder made it of little significance to use the prism array on the city wall, but Mohou used it in a small chariot array, like a fortress overgrown with hedgehogs.

"Yes, this array is indeed very useful, the border post is built with this array, the defense is greatly increased, and a very small number of people can make the enemy helpless and know the difficulty." Li Shimin nodded slightly, Datang reopened the Silk Road, and the border posts along the Silk Road are the top priority, with this array, the security of the Silk Road will be doubled.

No one thought that this school review had not yet begun, and the Mo family would give them such a big surprise, and they finally knew that Tubo was unjustly defeated this time.

However, the bigger surprise is still to come, a small iron thistle Mo family is actually playing superbly, one especially the iron thistle sprinkled on the ground not to mention for the time being, not to mention Li Shimin and the generals, even the civil officials know a lot about it.

What really stunned them was the iron thistle made of steel cables wrapped around the car array, especially above the car formation, the roll of iron thistle terrestris had spikes on it, and the whole car formation was like a hedgehog, making people unable to start.

Cheng Biting Jin was itching, picked up the horse lance and stepped forward to test the power of this new type of thistle terrestris, but even if Cheng Biting Jin was so fierce, it was able to cut through an iron thistle, and the remaining several other iron thistles were still like a roadblock, intact.

Cheng Yanjin's face was embarrassed, as long as he was given time, he naturally had the confidence to cut off these troublesome thistles, but at this time, he probably didn't know how many arrows he had been hit in.

"This thing is better than rejecting a horse." Cheng Yanjin returned from frustration and immediately praised. Tribulus terrestris is tough, not easy to destroy, and small in size, can be rolled into a roll for easy carrying, plus it has its own spikes, it is simply the nemesis of cavalry.

The generals nodded their heads, this was the preparation stage, and they already felt that the trip was worthwhile.
