After the prosperous Tang Dynasty

When the sun rises in the east and the northwest border area, looking up, you can see the ancient yellow sand road, Populus euphratica and red maple trees. When the wind and sand are swept up by the wind, it emits another long and bleak tone, revealing a unique desolation in the northwest region. .

The angel who came out of Chang'an City finally arrived at the Northwest Camp after a long and dusty journey.

When Wang Sili came out of his room, he had just woken up from his sleep. After washing, there were still some drops of wet water between his temples, except for his eyes, which showed a calm and slightly tired indifference.

A confidant of Wang Zhongsi's side just slipped over all the way, dexterously moved over and reminded Wang Sili in a low voice: "It's an angel in the palace, I think it's because of the Battle of Shibao City, the general let you go."

"What are you calling me for?" Wang Sili sneered lowly. Although he was very close to Wang Zhongsi, Wang Sili still found it difficult to accept the tragic battle in Shibao City.

The corpses of many lieutenant soldiers are still piled up on the endless yellow sand, and after a few years, they will wither into bones and be buried under the vast dust.

Whether it hurts its kind or empathizes with it, Wang Sili, as a bystander, had a lot of resistance to this incident during the Battle of Stone Fort City. Heart tormented.In the barracks under his command, countless comrades are in Meteorite Fortress, and the atmosphere in the army has been particularly sluggish recently.

The confidant soldier also smiled embarrassingly, just sighed, and said in a low voice: "After all, he is an angel from the palace." After a pause, he continued: "The general also hopes that you can go there."

Wang Zhongsi himself valued Wang Sili very much, and he was in the camp under his command. Even though Wang Sili is not a general now, he has always been regarded as Wang Zhongsi's heir. The importance of such a special status is naturally it goes without saying.

Wang Sili twitched the corners of his mouth, lowered his eyes slightly, and said indifferently, "I see."

When Wang Sili found Wang Zhongsi and the angel sent by Xuanzong, the two people in the room were discussing the follow-up of the Battle of Shibao City, but most of them were the messenger angel who said that Wang Zhongsi just followed casually. Smile, just echo a few words.

Seeing Wang Sili coming in, the angel finally paused for a while, turned around, and after Wang Sili took the initiative to say hello, he naturally gave a few words of praise with a smile on his face, and then returned to the topic.

In the Battle of Stone Castle, the Tang Dynasty suffered heavy losses. Even if they won such a battle in the end, Wang Sili still believed that this was a meaningless battle at present, let alone that Stone Castle During World War I, the Tang Dynasty had filled in the lives of tens of thousands of soldiers...

At least in Wang Sili's view, with such a large investment and loss, in the end, he just captured a stone castle first. Between Tang and Tubo, who will win this battle, I really don't want to say much...

The more he listened to the angel praising the Battle of Shibao City, the more upset Wang Sili became. As for what the angel specifically emphasized at the end, Xuanzong rewarded Ge Shu, the general of this battle, in the Xingqing Palace. When Wang Sili heard about John, he just felt speechless.

Until Wang Zhongsi hosted a banquet in the army to entertain the angel, Wang Sili, who was accompanying him, was still a little absent-minded. After asking people to take the angel who passed the edict back to the camp to rest, he opened his mouth and reminded him as gently as possible: "That angel, after all, represents the will of the saint."

Wang Sili wanted to sneer, but held back anyway, just pulled the corners of his mouth with a cold face, and said slowly: "Don't worry, I know."

Seeing this, Wang Zhongsi could only sigh, feeling that Wang Sili's emotions during this time seemed unable to recover.

Apart from the bloody battle led by Ge Shuhan in Shibao City, which made Wang Sili feel annoyed and speechless, the messenger who came all the way from Chang'an City brought another imperial edict from Xuanzong, which was It is closely related to many Jiedu envoys.

Several important towns under Wang Zhongsi's command were assigned to Ge Shuhan as the new Jiedu envoy.

When the wine was in full swing, under Wang Sili's intentional inducement, the angel naturally revealed that Xuanzong's new arrangement for Anlu Mountain, who had served as the governor of Anxi's four towns, was in the northeast area, which also belonged to the border of the Tang Dynasty...

Early the next morning, after leaving the edict, the angel from Chang'an City naturally left the Northwest Camp very quickly, with the clear purpose of meeting other envoys from the frontiers besides Wang Zhongsi, and An Lushan was naturally among them.

It was only after the people left that Wang Sili frowned, and said with a sneering sneer: "The arrangement of the sage is simple and clear. Judging from this posture, it seems that he wants to gather the power in the hands of the Jiedu envoys..."

Wang Zhongsi followed suit with a sigh, glanced at Wang Sili, and said mockingly, "It's a good thing the angel left early that day, otherwise, wouldn't you have to worry about it all the time?"

Wang Sili was angry and funny, and couldn't help rolling his eyes, but, facing Wang Zhongsi, he didn't want to continue to sneer.

A few more days passed, and after the meritorious deeds were rewarded, Ge Shuhan personally came to the Northwest Camp to meet Wang Zhongsi in private.

As for Wang Sili, apart from sitting down and drinking two glasses with Wang Zhongsi, he finally didn't say anything more this time.

It was also a coincidence that before Ge Shuhan left, a soldier sent a letter to Wang Sili.

"Who?" When Wang Sili received the frighteningly thick letter in his hands, he was still muttering casually, but when he saw the particularly regular and familiar characters on the new envelope, his movements stopped. for a moment.

The soldier who helped to deliver the letter replied with some excitement: "It's the Mr. Xiao who has already retired!"

When Wang Sili heard this, he just smiled, noncommittal.

When he was chatting with Wang Zhongsi before, he really sent something in the name of writing a letter to Xiao Song, but in fact, although Wang Sili respected Xiao Song quite a lot, the two were really not the same .

In comparison, it is self-evident who Wang Sili's previous letter was directed at.

Holding such a thick letter, Wang Sili turned around and went back to the study, and then opened the thick envelope by himself.

Xiao Yansui's letter was particularly rich in content, but what surprised Wang Sili was that the envelope contained such a thick content, but there was not a single word in it.

"This—" Wang Sili was quite shocked when he looked at those familiar and unfamiliar blueprints.

He had indeed raised questions to Xiao Yansui before, but most of them were just playing along, Wang Sili did not expect that Xiao Yansui would send him a letter for the second time, and the contents were all complete ordnance blueprints...

Especially when thinking of the recent Battle of Stone Fort City, if at that time, the army in the northwest had these large machines, perhaps, the situation of the war would be another scene.

·

Regardless of Wang Sili's mood after receiving this great gift suddenly, at least, to Xiao Yansui, the ordnance blueprints are all for the first time, and the most important thing is the only architectural blueprint that is not an ordnance kang plus floor heating. I don't know if Wang Sili, who is far away in the northwest, will notice this.

Time passed like water, and it was winter in a blink of an eye.

The weather is getting colder every day, and the winter in the south of the Yangtze River, especially because of the humid climate, inevitably brings a bit of biting chill.

As a result, in the renovated and rebuilt yard, things like floor heating naturally all burned again.

Under Xiao Yansui's suggestion, Xiao Song, who was old and had been wearing a pair of wooden-framed glasses on the bridge of his nose all this time, simply moved to this extraordinarily warm courtyard.

The room with floor heating is as warm as spring, especially since the heat radiates from the ground from bottom to top, which makes people feel comfortable in itself.

A few days passed, and Xiao Song lived very comfortably every day. Not to mention, seeing his granddaughter still tossing every day for the greenhouse that he had agreed to prepare for him, Xiao Song was moved and couldn't help being excited and excited. curious.

Xiao Yansui herself didn't think about it that much. Anyway, for her, it was nothing more than trying to come up with more scientific and effective things under the existing conditions, and, in the Tang Dynasty, where the industrial level was about zero. Under the background of the times, all kinds of gadgets that will inevitably need a lot of things as substitutes are tinkered with.

It would be even better if these things could be promoted naturally in Tang Dynasty society.

After all, when Xiao Yansui was choosing many substitutes, she did carefully consider the practicality of the things she tinkered with.Although due to the huge difference in ideas due to the gap between the times, some things may not become popular among the crowd as smoothly as Xiao Yansui imagined, but the product of this kind of science and technology in practical application, originally That is, as long as it can gradually spread, it will actually improve the technological level of the entire society.

——At least, Xiao Yansui believes that if she can find a substitute for plastic film and the price of this substitute is low enough, maybe next winter, there will be courageous people in the surrounding villages who have been tinkering with vegetable greenhouses.

After Xiao Song lived in the comfortable new house for a few days, the conservatory in the yard as an ornamental was finally completed. Except for the beams, frames and other parts, the roof and wall covering of the entire conservatory were all specially fired. In addition, in order to improve the toughness of the glass, Xiao Yansui deliberately pondered for a long time, just taking advantage of the opportunity when the temperature outside in winter was low enough, he adopted the basic manufacturing process of toughened glass, and signaled to those craftsmen that they were firing glass. When the glass material starts to soften slightly at about 600-650 degrees Celsius, take it out and blow the north wind in winter to cool it rapidly, so as to improve the toughness of the glass.
