"Ms. sir~! Has something happened in the past few days? I have always looked sad when I saw you~!"
That night.
The west courtyard of Li Mansion.
Han Yuxi asked softly from behind while helping Li Zexuan undress and untie him.
"Well, something happened~! Madam, do you still remember the assassin in the east of Chang'an City a few days ago~?"
Li Zexuan nodded and said.
Husband and wife are one body, and the Seventh Xiu Sect is not a very powerful force in Li Zexuan's eyes, so he feels there is no need to hide it from his wife.
Han Yuxi's hand holding the clothes shook suddenly, and she saw her brows furrowed, her voice suddenly turned cold, and she replied:
"Of course I remember~! That man caused my husband to be injured. If I had the ability, I would cut him into pieces~!"
Li Zexuan chuckled, turned around, took Han Yuxi into his arms, and said:
"Haha~! Men can do all these fighting and killing things~! Madam, just eat well and have a good rest~!"
Han Yuxi said angrily: "Eat well, drink well and rest well, wouldn't that make me a pig~?"
"Haha~! What happened to the pig~? The pig is still the second smartest little animal in the world~!"
"Go~! Sir, don't be poor, let's get down to business~! What did you mean when you mentioned the assassin just now~? Could it be that you met him again in the past few days~?"
Han Yuxi rolled her eyes at Li Zexuan, and then asked seriously.
"Hmm~! That's not true~!"
Li Zexuan pulled Han Yuxi and lay half on the bed together, and then continued: "Yesterday, I accidentally heard from Wang Renbiao's house about the origin of the assassin. It was said that he was from the Seventh Cultivator Sect in Sheling Mountain. Then I went to Jingzhao Mansion to ask Hua Fu Yin helped me check the specific location of Snake Spirit Mountain~! I think there should be results in a few days~!"
"Sheling Mountain~?"
Han Yuxi muttered it, but after all, she still felt that she had never heard it before, so she continued: "I hope Jingzhao Mansion can bring this assassin to justice, otherwise I will always feel uneasy~!"
Although Li Zexuan knew in his heart that this matter would not be solved so easily, he still expressed comfort and said: "I will, I will~! I will definitely catch the assassin this time~! Madam~, let's rest early~! "
"Hmm~!"
.............................
"Huh~? This cement is really interesting~!"
In the Manna Hall, candlelight was still lit late at night.
Li Er played with a palm-sized cement block on the dragon case and smiled meaningfully.
Sitting next to him was Queen Changsun.
The couple didn't sleep in Lizheng Hall in the middle of the night, but came to Ganlu Hall to work. I don't know what they were thinking.
"Your Majesty, is this what Qingque brought back today~?"
Queen Changsun asked curiously.
"Haha~! Exactly~! It is said that this is a new material specially developed by Li Zexuan at the Qiquge Workshop to replace glutinous rice mortar. Now it seems that the effect is surprisingly good~!"
Li Er sighed and handed a large piece of cement to Queen Changsun.
I don’t know where this guy Li Tai brought back a piece of cement pavement he smashed from the construction site. I guess a craftsman will scold me again tomorrow!
"Wow~! It's so strong~! Your Majesty, is this large piece made of cement~?"
Queen Changsun took it and squeezed it with her hands. She was surprised and asked hurriedly.
"Well, it's true! The shaping ability of this cement is better than that of glutinous rice mortar! Li Zexuan has brought another new thing to Datang that is more practical and cheaper!"
Li Er sighed with a look on his face.
"Huh~? How did your Majesty know that this cement is cheaper than glutinous rice mortar~?"
Queen Changsun asked curiously.
"Ha~! Needless to say~? You can guess it. If the cost of this thing is higher than that of glutinous rice mortar, how could Li Zexuan bother to study it~? I estimate that the ingredients in this cement should be some sand and lime That’s all, it doesn’t contain any expensive ingredients!”
If Li Zexuan were here, he would definitely give Li Er a wave of "6666666". Lao Li's initial guess was such that he had no friends!
"Hmm~! In that case, if this cement had appeared ten years earlier, wouldn't it be possible to save a lot of money on the city wall of Chang'an City? Besides, if the city wall is built with cement, it should be stronger, right?"
Queen Changsun said with regret.
The predecessor of Chang'an, the capital of the Tang Dynasty, was Daxing City, which was built under the leadership of Yu Wenkai in the early Sui Dynasty. "Yuanhe County Map" records: "In the capital of the Sui family camp, Yu Wenkai used the six high slopes north and south of Zhuque Street as the Qian Gua. Xiang, so the palace was built with ninety-two to serve as the residence of the emperor, the hundred divisions were established with ninety-three, to correspond to the number of gentlemen, and the noble position of ninety-five was not wanted for ordinary people to live there, so Xuandu Temple and Xingshan Temple were built to control it. ." It means to design the overall layout of the capital with reference to the Zhouyi Xiangshu theory and the six lines of the Qianfu.
In the first year of Wude, when the Tang Dynasty was first established, Li Yuan ordered Yan Lide to rebuild the outer city of Chang'an City.
The mileage of the Tang Dynasty was 360 steps per mile for a large distance and 300 steps for a small distance; 12 inches for a large scale and 10 inches for a small scale. At that time, Chang'an City used the large scale and the large scale to calculate the length of the outer city wall. The total length has reached about 36 kilometers. At that time, it was undoubtedly a magnificent project without parallel in the world. Of course, the money wasted was also an astronomical figure.
Therefore, Queen Changsun would feel a little regretful after seeing the cement.
Since the "Wei River Alliance" last year, Li Er has been worrying about money. Queen Changsun will naturally be particularly sensitive and concerned about saving money.
"Haha~! The matter has come to this, there is no use in talking~! What's more, no matter how strong the city wall is, it will be useless if it encounters a truly powerful enemy! The soldiers of my Datang are the strongest city wall of my Datang~! If If the descendants of future generations fail to live up to expectations and are forced to huddle within the city walls when foreign armies attack the city, then I think it would be better to subjugate the country~! In my Tang Dynasty, all barbarians must surrender and all nations will be afraid~! No one will be able to attack Chang'an again. The city is here~!”
Speaking of city walls, Li Er suddenly remembered that last year, the two Khans Jieli and Tuli led 200,000 Turkic troops to line up on the Wei River and march to the gates of Chang'an. That time, if Jie Li had been braver and attacked Chang'an City without hesitation, even though the walls of Chang'an City were as high as majestic, he might not have been able to withstand the attack of these 200,000 soldiers. This gave Li Er a new understanding of city walls. In my opinion, it is better to defend than to attack!
This is the difference between Li Er and later kings! If Li Zexuan had traveled back in time to the Song Dynasty or the mid-to-late Ming Dynasty, if cement had been produced again, there would be a 90% chance that the monarch at that time would have used cement to strengthen city walls and defend against foreign enemies. They are "upgrading armor" to ensure survival, while Li Er's pursuit is to use offense instead of defense. When all enemies are frightened, there will naturally be no need for city walls to defend against foreign enemies!
