Li Shimin needed time to digest Xia Hongsheng's theory that war could make the country wealthy, so he didn't hear any news from the palace for the next few days, and there was a court meeting in the middle, and the emperor and those ministers also seemed to have made an appointment, and never mentioned Turkic affairs.

On this day, Xia Hongsheng still went to the East Palace to accompany Li Chengqian to study. Li Gang was teaching the course in front, and Li Chengqian sat down honestly, his hands on the desk, and stared at the book on the desk seriously—by the way, the book was reprinted by Kong Yingda and a group of scholars with punctuation marks and printed by movable type printing. Nowadays, the printing workshops of the official families are printing day and night, and a large number of new classics will be distributed to the official schools in various states and counties for the use of scholars.

Xia Hongsheng is not in the mood to write about the Three Kingdoms today, because the glass kiln on Zhuangzi is about to burn the first batch of things, he is worried about the output of the glass kiln, and he is anxious to wait until it is over so that he can rush back to Jingyang to see, and the cement kiln to see if the burned cement can be put into use, and if it can be used, it can be used to build a military academy.

So at this time, Xia Hongsheng had no intention of writing about the Three Kingdoms, and he had no intention of listening to the lecture. His mind was full of glass kilns and cement, and he even began to build what he should build a military academy into.

"His Royal Highness the Crown Prince!" A low, but majestic shout sounded beside Xia Hongsheng, waking Xia Hongsheng up from his imagination, and when he turned his head, he saw Li Gang standing beside Li Chengqian with a serious face. Li Chengqian was obviously taken aback, and quickly covered the things on the desk with his two arms.

"Bring it!" Li Gang stared at Li Chengqian sternly and said. The ring ruler has been raised in his hand.

Li Chengqian's face became a little pale, and he looked at Xia Hongsheng with pleading eyes, and then at Li Gang. However, Li Gang had no intention of bypassing him and stretched out his hand. grabbed the thing that Li Chengqian was holding with both hands and dragged it out.

Only then did Xia Hongsheng see clearly what it was, it was the chapters that Li Chengqian borrowed from him. This thing dares to secretly read extracurricular books when Li Gang is lecturing! It's over, Li Gang won't tear it up, right?

Li Gang snorted coldly, stared at Li Chengqian, and said in a deep voice: "His Royal Highness the Prince, please raise your hand!" ”

As soon as Li Chengqian heard this, he said. Suddenly, like a wilted turnip, he lowered his head in frustration and stretched out his hand. Li Gang showed no mercy, the ring ruler in his hand was raised high, and then fell heavily on Li Chengqian's palm, making a crisp sound. After hitting ten rings in a row, Li Chengqian's left palm became red and swollen.

"It's the student's mistake, please forgive the teacher!" After being beaten, Li Chengqian went down deeply. apologized to Li Gang.

Look, what a respect for teachers! In the future, if any teacher beats a student's hand because the student violates class discipline, it will be a big deal. I remember a colleague in the past, because the student cut the hair of the girl in the front seat during class, so he kicked him twice in the buttocks, and the student went home and told the parents, and the parents took a group of people to the school to beat the colleague in front of the whole school, and got it to the end. The school also gave the colleague a punishment, saying that he hit the student first...... What a world of difference!

Li Gang asked Li Chengqian to sit back. But he wasn't lecturing either, telling the two that they could finish. The two respectfully sent Li Gang away, turned around, and Xia Hongsheng grabbed Li Chengqian's collar.

"Uh, Shizuki, Calm Anger...... ...... angry, Li Chengqian smiled and said to Xia Hongsheng: "I watched it last night. I really couldn't take it, and I wanted to know what was going on when I was in class, so I couldn't hold back for a while......"

"Don't tell me these useless things, you go to Master Li to come back for me!" Xia Hongsheng frowned coldly at Li Chengqian: "That's my hard work for several months, and I still expect to be collected and printed after I finish writing!" That's good. I was by you all of a sudden! How will you write it in the future?! ”

"Huh?!" When Li Chengqian heard this, he immediately patted his chest and said, "Don't worry, Jingshi, hold me!" I'll get you back!" It's a big deal to be scolded by Master Li! ”

Xia Hongsheng glanced at Li Chengqian, who patted his chest with a righteous and awe-inspiring look: "I originally complained about you, you have to give me back, regardless of whether you were scolded or beaten!" ”

Li Chengqian curried over and begged for mercy, and the two said a few more words, and Xia Hongsheng left in a hurry.

"Jingshi, why are you in such a hurry? By the way, yesterday the third brother also told me that there is a good place in Chang'an City, and the weather is very good today, why don't you and I go to the third brother to go over and see? Li Chengqian saw that Xia Hongsheng was in a hurry to leave, so he said.

"I just wanted to go out to play after being beaten, and I deserved to be a big man in Chang'an!" Xia Hongsheng rolled his eyes and said: "I'm afraid I won't be able to go today, I have to go back to Zhuangzi, the first batch of finished products in the glass kiln today, I have to go and see the condition." ”

"Something from the glass kiln?" Li Chengqian's eyes lit up: "Speaking of which, Gu is also one of the shareholders of the glass kiln, well, since the finished product is produced today, Gu naturally has to go to inspect it." Let's go, let's go! ”

Xia Hongsheng was even more contemptuous, and if he wanted to go out to let off steam, he would just say it, and simply let Li Gang tell Li Lao Er what happened just now, and let Li Lao Er give him a few months of grounding!

After Li Chengqian changed into civilian clothes, brought the guards, and the two went out to the Suzaku Gate together, they happened to see Li Ke walking slowly towards this side, followed by a small Li Tai, the two of them seemed to be talking about something, Li Tai's face was cold, Li Ke's face was flattering, which made Xia Hongsheng and Li Chengqian curious.

When he got closer, Li Ke saw that Li Chengqian was wearing civilian clothes, so he asked, "Big brother wants to travel?" Today I was going to ask my eldest brother to go to see that good place, but Clinker Qingque followed me alive...... I asked him to go back first, and he didn't go back! ”

"Well, something has come out of Jingshi's glass kiln today, and I'm about to go and have a look." Li Chengqian looked at the two of them and said.

Seeing that the eyes of those two people lit up with Li Chengqian, Xia Hongsheng knew that there were two more people on this trip.

The four of them left Chang'an City together, it was almost noon at this time, Xia Hongsheng was in a hurry to go back, so he simply didn't eat, and he hurriedly whipped up, and finally rushed back to Zhuangzi in the second half of the day.

ran to the kiln, and saw a ten-step square cement floor in front of him, Xia Hongsheng immediately turned over and dismounted, and walked up. The rest of the people also came down, walked up curiously, squatted on the ground with Xia Hongsheng, and touched the buckle on the ground like Xia Hongsheng.

"Qi Yong, come with a knife!" Xia Hongsheng raised his head and said to Qi Yong. Qi Yong immediately untied the saber and handed it to Xia Hongsheng, who took the knife and slashed the cement a few times, and then smashed it several times with the knife. Looking at the concrete floor, there is no trace left.

"Great!" Xia Hongsheng waved his fist excitedly. Sure enough, the pavement paved with hard gravel mixed with cement is very explaining, although it is not as good as asphalt, but it is much more expensive than today's sandy roads.

When I looked up, I saw that there was a one-man high masonry wall erected behind the concrete floor, but the middle of the masonry wall was not the common yellow mud or the like, but was built together with cement.

Xia Hongsheng walked over and pushed the wall, and then said to Qi Yong: "Qi Yong, you come and kick hard!" ”

Qi Yong nodded, and a little like a crazy person ran to the half of the wall, and his legs sank and shouted violently, and one leg was pumped to the half of the wall. The wall didn't even react at all, but Qi Yong himself was bounced back and retreated several steps.

"Qi Yong, I'll give you a task." Qi Yong, who felt a little embarrassed because Xia Hongsheng was bounced back, said: "You bring a few people another day, and the thing that hit the wall hits him and collapses, understand?" ”

"Yes!" Qi Yong agreed.

At this time, the trio of the old Li family, who had been watching for a long time, finally couldn't help it, Li Ke came over and said to Xia Hongsheng: "I said brother, what are you doing?" ”

Xia Hongsheng smiled mysteriously and said, "This is a baby, much more precious than Liuli!" ”

After speaking, Xia Hongsheng left there and walked towards the kiln.

Several kilns were in full swing, and the housekeepers and bookkeepers in the house all came, and the craftsmen in other workshops also gathered there to watch the excitement. The old kiln head was constantly shouting and directing the potters, and when Xia Hongsheng passed, he saw the potters retreating the things in the kiln.

"Is it annealed?" Xia Hongsheng stepped forward and asked.

The old kiln head turned around, only to find that Xia Hongsheng was coming, so he hurriedly saluted, and then replied: "If you return to Gongzi, it was burned yesterday, and one is annealed until now, and then it starts to be taken outside." In the middle, according to the instructions of the childe, the temperature in the kiln was gradually lowered. However, this first batch is a test kiln, and it is not blown, and it will not take shape when it comes out. ”

Xia Hongsheng nodded, and when the potter withdrew from the kiln, he hurriedly walked over, and saw that pieces of crystal blocks that were still transparent were picked out.

"What a glass!" Li Chengqian exclaimed in surprise and looked at a large pile of crystal blocks in front of him: "Translucent!" It is much brighter than what Hu Shang sells. ”

Hehe smiled, Xia Hongsheng turned around and ordered: "Go, bring boiling water and ice water!" ”

This is something that Xia Hongsheng has already explained, and the housekeeper immediately ordered the two of them to come over. I found two wooden basins, each with a few pieces of that kind in it, and then a basin of boiling water, and a basin of ice water was poured into it at once.

After a while, Xia Hongsheng immediately burst into laughter.

Not crushed!

Sure enough, it is the problem of annealing, the original glass has not gone through the annealing process, and it will be crushed when it is filled with hot water, and these crystals are intact and not broken!

"That's it!" Xia Hongsheng smiled and said to the old kiln head: "Very good, go to the housekeeper to receive the reward!" Next time, try blowing, don't need too complicated shapes, just blow a few cups, and then try it with boiling water! (To be continued......)
