It seems that Li Tai's whole aura has suppressed his own head, he used to see Li Tai as a fat man, but now it seems that Li Tai's whole person seems to be alive.

Li Tai said to Li Chengqian again: "Let the imperial brother worry." ”

"Hmm......" Li Chengqian was a little suffocated, thought for a moment and then said, "I want to go to see my father." ”

"Coincidentally, my brother will go too." Li Tai said.

The two brothers walked together to the temple of manna.

Li Shimin was looking at the roster handed over by Wang Ding, and knew that it was Li Chengqian and Li Tai who came and said to Wang Ding: "Let them in." ”

Wang Ding nodded and led Li Chengqian and Li Tai into the door together.

Li Shimin raised his eyes and glanced at the two brothers.

"I've seen my father!"

Li Chengqian and Li Tai saluted together.

Li Shimin looked at the two brothers compared to Li Chengqian, Li Tai looked a lot taller than before, and Li Tai, who was a little short on weekdays, now looks a lot taller.

"How's the roster of the ministry being prepared?"

Hearing Li Shimin's question, Li Chengqian replied: "Father, the Ministry of Officials has preliminarily drawn up a roster of officials for promotion, and it can be handed over to Zhongshu Province in the near future. ”

Li Shimin nodded and looked at Li Tai again, "Qingque, you must also pay close attention to the compilation of the Kuodi Chronicles, even if you live in Jingyang now, you can't leave behind the compilation of the Kuodi Chronicles." ”

Li Tai bowed and said, "Erchen understands. ”

"It's rare to come back and meet your mother."

Li Tai saluted again, "Wow." ”

The two brothers walked out of the Ganlu Palace, and Li Chengqian looked at the back of Li Tai leaving, and always felt that the current Qingque had changed a lot from before.

Li Chengqian felt that he was inexplicably unconfident in front of Li Tai.

Now it seems that Li Tai's aura is different from before, including the tone of voice when he speaks.

Li Shimin finished his work and stood up and went back to the political hall.

Gao Yang has been getting more and more naughty recently, and Gao Yang, who is only five years old, is still a little rebellious.

In addition to His Majesty and the Queen, on weekdays, Lizhi can control Gao Yang, and Gao Yang will also listen to Liqin's words.

Li Li taught Gao Yang how to wear his own shoes, and Gao Yang always couldn't wear his own shoes.

Seeing that his father was back, Li Lizhi stood up and said, "Father." ”

Li Shimin nodded slightly and walked into the Legislative Palace, Li Tai was talking to his mother about his days in Jingyang.

Li Tai must have suffered a lot to lose weight, and I heard Li Tai say that he was still working in the blacksmith shop in Jingyang.

Empress Eldest Sun was even more worried, "Tell me about a half-old child, what do you do with iron." ”

Li Tai grinned and said, "Li Zheng can strike iron, why can't the child." ”

Now Li Tai is fifteen years old, it is the time to grow his body, he didn't come back for a while, and he grew taller again in a blink of an eye.

Li Shimin sat down in the Lizheng Palace, and listened to Li Tai's words and unconsciously glanced at it, now Li Tai is a little darker and thinner.

The pampered prince works in the blacksmith shop on weekdays, and it is false to say that he is not distressed.

Li Shimin doesn't care so much, it's a good thing to be able to endure some hardships now in the future.

"Li Zheng can also forge iron?" Li Shimin asked in surprise.

Li Tai replied: "Father, Li Zheng has a very strange method of forging iron, and the forged steel knife is even tougher than our current steel knife. ”

Li Shimin hesitantly put down the teacup, "Strange wrought iron method? ”

"That's right." Li Tai poured tea for Li Shimin and said: "Li Zheng first burned and melted the pig iron, and then put in the wrought iron, what is it called the pouring cast iron method." ”

"Really?"

Li Tai nodded affirmatively, "The forged steel knife is very sharp and tough, and the child helped Li Zheng forge it with his own hands." ”

Striking iron, Li Shimin naturally knew that in the past, wrought iron to build weapons was the top priority.

"If you want to sinter iron, you need to have a very high fire temperature, did Li Zheng really burn the pig iron?"

Li Tai explained: "Li Zheng also has something called a wooden bellows, which can make the flame burn more vigorously. ”

Li Shimin took another sip of tea.

Li Tai whispered: "Father, Li Zheng's method of forging iron to make a billet of a steel knife only takes one day to make. ”

"Time for a day?" Li Shimin was surprised.

"That's right, it's a day." Li Tai nodded, "Li Zheng is using a tandem steelmaking method, which is very useful. ”

Li Shimin gasped, and it would take half a month for Datang to make a horizontal knife at the earliest.

The iron must be tempered and then forged.

Wang Ding hurriedly came to report: "Your Majesty, Cheng Biting Jin asked to see him, saying that there was a treasure knife created by Li Zheng to offer. ”

Li Shimin glanced at Li Tai and said with a smile: "This trip to bite gold is positive." ”

Li Tai: "Li Zheng gave this newly made steel knife to Cheng Chumo. ”

Li Shimin stood up and said, "Qingque, you go with me to see what Li Zheng's steel knife looks like." ”

In front of the Taiji Palace, Cheng Yanjin was standing here.

Li Shimin asked, "It is said that Li Zheng gave the knife to Chu Mo?" ”

Cheng Yanjin opened his mouth and said: "Your Majesty, Li Zheng, this kid is a thief, obviously he wants to give it to His Majesty, but he pretended to give it to Chu Mo." ”

After speaking, Cheng Biting Jin saluted Li Tai again, "I have seen His Royal Highness King Wei." ”

Li Shimin took the steel knife from the hands of the guards on the side.

Pulling the knife out of the scabbard, Li Shimin was dazzled by the reflection of the knife surface, and pulled the blade out of the scabbard completely.

Looking at the mirror-like steel knife, Li Shimin rubbed the back of the knife with his hand, "What a beautiful knife." ”

Cheng Yanjin nodded, "This knife is very sharp, Your Majesty might as well try it with a horizontal knife." ”

Li Shimin asked the guards on the side to pull out the horizontal knife, and called another guard to start testing the knife.

Li Tai knew the result of the knife test, and watched the guard in front of him keep looking at the horizontal knife with the new knife.

The sound of the knives clashing incessantly, and both knives were unscathed.

Cheng Yanjin said impatiently: "Let a certain family come, you people who haven't eaten enough can't make it hard." ”

After speaking, Cheng Yanjin took the new knife and said, "Hold your own knife steadily." ”

Cheng Yanjin held the knife above his head with both hands, and swung the knife vigorously with a loud shout, and a crisp metal collision sound sounded.

The horizontal knife in the guard's hand slashed a huge gap, and half of the blade of the new knife was already embedded in the horizontal knife.

Li Shimin stood up and watched this scene, breathing heavily.

Good knives! This was the first thought in Li Shimin's heart.

Cheng Yanjin picked up the new knife again, and the new knife was still unharmed.

Putting the knife back into the scabbard, Cheng Yanjin said, "Please also take a look at Your Majesty." ”

Li Shimin picked up the new knife, "I didn't expect this knife to be so sharp." ”

Cheng Yanjin said: "Your Majesty, if you want to say that the sharp horizontal knife is not bad, but this new knife is very tough, just by listening to the sound, you know that this is a good knife that is unique in ten thousand." ”

Li Shimin put away the excitement in his heart and asked, "How many such knives did Li Zheng make?" ”

Li Tai replied: "That's all, Li Zheng also said that he may not build weapons in the future." ”

"What did you say!" Li Shimin asked.
