From the end of August of the ninth year of Wude to the present, there are soldiers practicing shooting in front of the Xiande Hall every day, riding archery, foot shooting, and so on.

Li Er will also often personally teach those soldiers who are not familiar with archery, and if they perform well, they will also reward bows and arrows and other things.

The eldest grandson Wuji and others advised several times, saying that it was ominous for the blade to go to the front of the emperor, and hoped that Li Er would not be so willful again, and should think more about the country, for fear that this soldier would not control it well once, and he would kill Lao Li by going on a fire, and then the Tang Dynasty would collapse, but he was vetoed by Li Er every time.

In this way, the kings of the Tang Dynasty, during the Zhenguan period, saw that the emperor could bring a sword, and the previous dynasty could also bring a sword. This is also the reason why Wu Chen can walk in the inner palace with a knife full of his body.

All of this is illustrating a problem: Lao Li hates the Turks and Jieli very much.

Therefore, regarding the matter of sending troops to exterminate Jieli, there is no military force in the court, and the caliber is completely the same, that is, the two words 'engage him', as for how to do it...... With so many military generals here, others don't bother to think about it.

Because Li Chengqian had been acting as a general some time ago, he didn't run away this time, and rectifying armaments was his new task.

In other words, he is just a real and unknown logistics minister, and he is required to handle the armament, and he also needs to do the food needed for the war, not to mention the transportation, and the matter of water transportation happens to be under the jurisdiction of the capital water supervision.

"Your Highness, it's night, go back to the palace." will be used as the supervisor of the iron mill, and Wang Chenghu will come to urge Li Chengqian for the fourth time.

"Hit back, don't you see the critical time?" Li Chengqian, dressed in thick cloth clothes, stared at the steel-making furnace in front of him, and didn't even bother to wipe the sweat flowing into his eyes.

"Your Highness, can this really be done?" Liu Min, who was beside Li Chengqian, asked a little nervously, and rolled his eyes at Wang Chenghu's urging.

"Don't ask me, I don't know." Brushing away the beads of sweat from his face, Li Chengqian said to Liu Min: "If you are sure of this crucible, then you will definitely be able to do it, if you are not sure...... Then leave it to fate. ”

"Minister, minister can't guarantee it." Liu Min shook his head and once again focused on what Li Chengqian called a crucible in front of him.

After the crucible steelmaking method and refractory mold were widely used in the superintendent, Li Chengqian thought of the only way to quickly increase steel production.

Although the steel filling method is simple, the output is not very high, so Li Chengqian decided to abandon it after thinking about it for a long time and directly use the crucible to make steel.

It's the middle of October, and after more than ten failures in about two months, I finally prepared a material that can withstand high temperature burning without breaking.

And now it is the crucible made of that material that is being calcined in the furnace.

Time passed, but the crucible in the furnace was still strong, without a trace of deformation or fragmentation, and the iron ore inside the crucible was slowly melting.

"Your Highness, Your Highness, it's done, it's done." Liu Min's expression was very excited, and his hands kept trembling.

"Wait, it's not completely melted yet, wait and see." Li Chengqian's eyes were already red and swollen as he stared at the fire, and tears flowed out involuntarily one by one, but he still refused to take his eyes away.

Once again, the ironworks fell silent, except for the sound of the craftsmen stirring in the crucibles, and the 'crackling' of the coke burning.

"Your Highness, rest for a while, there should be no problem." Liu Min inadvertently turned his head, noticed Li Chengqian's current state, and was taken aback.

"Is it really okay?" Li Chengqian only knew that he could make steel in this way, but he didn't know anything about the specific heat and the like, and he could even say that he didn't even know the theory.

"No problem, if there is no problem with calcination for so long, it can already be determined. And if there was no crucible and I chose to calcinate it directly, I am afraid that those iron pieces would have turned into molten iron long ago. Liu Min said confidently.

"Okay, I'll go to your official office to take a rest, the matter has a result, remember to inform me." Li Chengqian was indeed a little unbearable, as if his eyes were not his own.

"Your Highness won't return to the palace?!" Liu Min asked with some surprise.

"Back to the fart, if this crucible steelmaking method is successful, do you know how much Datang's steel production will increase? In such a situation, how can you let this palace go back to the palace to sleep with peace of mind. Li Chengqian kept blinking his eyes and said angrily.

"Okay then, accompany Your Highness over." Liu Min nodded, and did not persuade again, in fact, it is not only Li Chengqian, he himself is also a virtue.

Now if someone asks him to go back to sleep, Liu Min may even pull out a knife and fight hard.

Li Chengqian pointed to the position where Liu Min was standing, and said almost word by word: "This palace doesn't need you to accompany you, you are here, don't go anywhere, just watch here, as long as you succeed, immediately go and tell this palace, do you hear!" ”

After seeing Liu Min nodding and agreeing, Li Chengqian was relieved to take Wu Chen, Wang Chenghu and Cheng Huaan to leave the iron-smelting workshop.

It was already very cold in Chang'an in October, but after staying in the hot environment of the ironworks for a long time, I only felt comfortable outside.

Breathe in a breath of cold air, and then slowly spit it out, cooling the lungs that are about to burn, Li Chengqian glanced back at the ironworks, and the corners of his mouth raised a trace of arc, Datang is really going to take off this time, and no one can stop it.

"Your Highness, can the new steelmaking method really increase steel production hundreds of times?" Cheng Huaan, who rarely spoke, said a rare word.

"Of course." Li Chengqian nodded affirmatively.

"Your Highness, what's the use of so much steel?" Wu Chen couldn't understand what the surplus steel would do after the steel production increased by hundreds of times.

"There are many uses, and when the time comes, all the rice bowls will be made of iron, the chopsticks will be made of iron, the tables will be made of iron, and the chairs will be made of iron...... In short, everything you can think of is iron. Li Chengqian said excitedly.

"All iron?" Wu Chen asked with a snort.

Li Chengqian didn't seem to intend to let go of the fragile nerves of Wang Chenghu and others, stretched out his hands to the sky, and said in a fanatical state: "The entire Datang is all iron, steel will change the entire Datang, the world will prostrate at the feet of the Datang, and countless barbarians will tremble and tremble in front of the Datang...... ”

Wu Chen looked at Li Chengqian, who was a little crazy, a little sluggishly, and didn't know what to say, he knew that Li Chengqian's mind was different from others, and he often had some incomprehensible ideas, and these ideas would always become reality soon.

But let the whole world crawl at the feet of Datang, countless barbarians trembled in front of Datang, no matter how it sounded, it sounded like a dream, too unbelievable.

It's very contradictory, very tangled, should we rely on past experience to believe in this prince who is about to go crazy?
