The news of the successful test firing of the artillery was transmitted to the palace as soon as possible, Li Shimin was ecstatic, looking at the strings of numbers on the secret report, the more he looked at it, the more happy he became, the effective range of nearly two kilometers, this is a weapon that has never appeared before, he directly waved his hand and ordered the start of mass production, hoping to equip the whole army as soon as possible!

Li Shimin was happy, but he took pity on Li Siyuan and the craftsmen of the secret base, although it was said that the order for mass production was given by Li Shimin, but at the same time he also issued an order of strict secrecy, which undoubtedly aggravated the difficulty of production, and the number of people who came to the base was not enough to produce on a large scale now, and the manpower became even more stretched!

Since the moment they received the order, Li Siyuan and they had been busy for a whole month, and they had only produced 50 cast iron cannons and 10 small steel cannons with an effective firing range of 2,500 meters!

Although he was not satisfied with such a production progress, when Li Shimin personally inspected the base secretly, he could only nod helplessly in approval!

With the passage of time, the whole Tang Dynasty is immersed in the joy of spring ploughing, since the imperial court promoted the Quyuan plow, every family has become extraordinarily labor-saving, and also has spare time and strength to open up wasteland, which undoubtedly gives the people more opportunities for food and clothing!

People seem to have gradually forgotten the threat of the Turks more than a month ago, and even Li Shimin was blinded by this peaceful atmosphere and the appearance of artillery, forgetting that the danger is still there!

"Report!" Just when Li Shimin listened to the eldest grandson Wuji's report on spring ploughing with a smile, a sad shout echoed in the entire palace: "Jieli led 100,000 troops, continuously broke through Lingzhou, Taiyuan and other cities, and went straight to Chang'an, General Cheng's Fan Gongzi was playing in Taiyuan, unfortunately he was captured by Jieli, when he heard that he was General Cheng's child, Jieli directly ordered the third prince to be hanged at the Taiyuan city gate!" "The Messenger! gave a general report of the situation, and then passed out with his eyes rolled over!

The messenger who passed out in a coma naturally had someone carry him down for treatment, and Li Shimin stood up with a lap on the dragon chair after hearing the news, his eyes full of incredulity.

Compared with Li Shimin's surprise, Cheng Yanjin almost fainted like a messenger at this time, but fortunately, in his heart, while full of sadness, hatred was also supporting his fragile nerves!

There was silence in the Taiji Palace, and after a long time, I heard Li Shimin sigh: "Alas, know the festival, mourn, I will definitely not let this child die in vain, I will definitely avenge him and the innocent soldiers who died!" ”

"Your Majesty!" Cheng Biting Jin screamed sadly, and trembled and knelt down in front of Li Shimin: "Wechen pleads, I beg Your Majesty to allow Wechen to take revenge in person!" ”

Li Shimin understands the pain in Cheng Biting Jin's heart at this time, the white-haired person sends the black-haired person, how many people can not be sad? But looking at Cheng Yanjin at this time, his eyes were red, not to mention, I am afraid that hatred has completely blinded his mind, Li Shimin asked with some concern: "Zhijie, your current appearance, I'm afraid it's not appropriate to lead the troops, why don't you stay at home and handle the aftermath for Chu Bi?" ”

"Wechen pleases you, I beg Your Majesty to allow Wechen to personally avenge my dead child!" Cheng Yanjin didn't say anything superfluous, he slammed his head on the ground, and then begged Li Shimin to allow him to go into battle to kill the enemy!

Staring at Cheng Yanjin, who was kneeling on the ground, for a while, Li Shimin returned to the dragon chair as if he had accepted his fate: "Okay, I will appoint you as the vanguard general now, and I will command 20,000 troops, but I can break it at the moment!" ”

"Li Jing listens to the seal!" Li Shimin continued: "I ordered you to be the commander of the three armies, commanding 100,000 troops, and you can choose the civil and military forces of the Manchu Dynasty. ”

Cheng biting Jin and Li Jing hurriedly thanked them, and they each returned!

Li Shimin, who was on the dragon chair, his eyes widened angrily, and shouted loudly: "The Turkic wolf ambition has repeatedly offended my Central Plains, this time, I will definitely want them to come and go!" ”

After finishing speaking, he said to the eldest grandson Wuji: "Proposed order, order Li Siyuan to bring all the artillery tomorrow and go to the royal training ground to prepare for test firing, after the 3rd, all the artillery will go out with the army, and if you don't destroy the Turks, you won't return it!" ”

Li Siyuan and Li Shimin both did a very good job of secrecy, at this time, all the people in the palace were a little dazed after hearing the word artillery, only Cheng Yanjin was happy, and felt that revenge was easier!

When Li Siyuan received the holy decree, he looked at the father-in-law who came to deliver the decree with some surprise and asked: "This father-in-law, I don't know what happened, Your Majesty actually wants to mobilize all the artillery?" ”

After seeing that there was no one around, the father-in-law retold the whole story of the matter to Li Siyuan as it was.

No wonder Li Shimin just finished inspecting this place not long ago, and he mobilized all the artillery again, Li Siyuan's heart suddenly brightened, this is revenge and Liwei!

Not daring to slack off in the slightest, Li Siyuan hurriedly ordered the inspection and maintenance of the artillery, and at the same time ordered the artillery shell workshop to speed up the research and production of solid ammunition in case of emergency!

Whether it was out of personal friendship with Cheng Yanjin or heartfelt to Datang, Li Siyuan didn't want this battle to be lost in his own hands.

After arranging the affairs of the base in full swing, Li Siyuan took the time to go home and tell his family about the matter, because he didn't know if there would be time to say goodbye to them in the next days, so he could only talk to them so briefly!

Looking at his wife, whose belly was bulging day by day, Li Siyuan gently kissed her on the stomach: "Baby, wait for me to go home!" After that, he got on his fast horse and hurried back to the base!

Although I don't know if her husband's baby shouting is the person in her stomach or herself, Li Sisi's heart feels the same warmth, she knows that her husband can not go to the battlefield, but no one in the entire Tang Dynasty knows more about artillery than Li Siyuan, out of responsibility, Li Siyuan is not allowed to escape, this is the man she Li Sisi wants to marry, a man who dares to take responsibility and knows how to take responsibility!

At the royal training ground, 60 artillery pieces shone with black light, and the dark muzzles pointed straight to the sky, and hundreds of officials looked curiously at the artillery in front of them and the shadowy targets in the distance.

"Your Majesty, you can begin!" The little eunuch on the side reminded Li Shimin that the time was up.

Looking up at the sun, Li Shimin nodded, and the herald behind him hurriedly shouted: "Prepare to open fire!" ”

Hearing the herald's shout, Li Siyuan shouted loudly: "Artillery salvo, elevation angle 30, ready!" ”

There was a rush on the training ground, and one artillery was equipped with two personnel, one for loading and the other for firing.

So much so that after observing that the field was basically loaded, he shouted loudly: "Fire!" ”

I saw the soldiers holding torches on the side at the same time lit the fuse on the cannon, and after a while, I felt the earth shake, and then a deafening roar resounded in the sky, and the distant targets fell in rows, and the scene was very spectacular!
