Tang Dynasty: The beginning of the game is to touch the Princess Changle

"What kind of building is this?"

In the study, Li Tai took the drawing Su Chen gave him and looked at it for a long time but couldn't understand it.

It looks like a pigsty, but it doesn't feel like it.

The pigsty doesn't have a rounded roof.

"They all know how to prepare explosives, right?" Su Chen asked with a smile.

Li Tai nodded.

It's actually not difficult to prepare explosives. As long as you provide the ratio of each material, anyone who knows how to scale can do it.

"Your next task is to get this out." Su Chen pointed to the sketch of the greenhouse in Li Tai's hand and said.

As shown in the sketch of the greenhouse, a circle of low walls about three feet high is built with red bricks at the bottom, and a doorway is reserved for one entrance and one exit.

"What is this structure used for?" Li Tai was still puzzled.

"This is called a greenhouse, and you can grow leafy vegetables in winter." Su Chen finally remembered to build a greenhouse.

Li Tai instantly became very interested and asked, "How to do it?"

"I asked you how to do it! I can do it myself, why do I need you?" Su Chen said this, not feeling embarrassed at all.

Li Tai scratched his head while looking at the sketch, feeling that this was not difficult, and asked:

"Tell me, what effect should be achieved to grow off-season vegetables in winter!"

Su Chen nodded with satisfaction, "You have asked the right person! I tell you, the greenhouse is as clear as it gets: it is to ensure that the temperature inside the greenhouse is higher than the outdoor temperature."

"Therefore, the greenhouse should be able to: block wind and rain but let light in, and not block the sunlight."

Not being able to do it does not mean not being able to say it. Make your ideas and requirements clear, there are many skilled craftsmen in the Tang Dynasty.

Li Tai nodded thoughtfully after hearing this.

Su Chen knew from Li Tai's eyes, and smiled: "Did you think of using glass? I thought so too!"

Li Tai nodded silently and asked: "Why is the top curved?"

"To prevent it from being crushed by heavy snow! It can also effectively prevent water from accumulating on the top. And the arch structure has good stress resistance. Think about the arch bridge and you will understand." Su Chen gave the answer without thinking.

As for the other things, Su Chen didn't understand, maybe it was related to air circulation.

"What you need to solve is what material to use to build the arch. The glass must not be too large, and it needs to be embedded in the arch component." Su Chen added a reminder.

Li Tai nodded, looked at Su Chen and said: "Have you ever noticed the wheels of the carriage?"

"Wheels?"

Su Chen didn't understand, and carefully recalled the shape of the wheel.

"Yes! The wheel is made of wood segments and joined into a circle. Since it can be joined into a circle, it can certainly be joined into an arc."

"Then inlay the glass from the two slots, and finally connect the spliced ​​arched columns with crossbars."

"Perfect!"

Su Chen clapped his hands vigorously.

Li Tai smiled slightly, "You shouldn't ask me for this matter, Li Dejian is an expert in this. I can help you make the curved glass according to the agreed arc."

"Okay, it's best to make the glass 45 by 90! Let's try it on half an acre of land first."

"45 by 90?" Li Tai asked in confusion.

"Oh, glass that is one and a half feet wide and three feet long. The glass should be made after the arch frame is built, so as to avoid the size and arc not being right." Su Chen thought for a while and reminded.

"Okay, I know." This was Li Tai's original plan.

Su Chen was excited when he thought about it. If the greenhouse was successfully built, he would not have to worry about not having vegetables to eat in the winter.

Sweet potato leaves are yellow and old at this time, and are not suitable for cooking.

"Let's go, it's almost time to eat. I'll go find Li Dejian in the afternoon."

Su Chen got up and walked out of the study...

15:00 pm (17:15).

The sun sets early in winter, and the shadows of pedestrians on the road are long.

Li Chengqian's family visit team reached Maweiyi, west of Xingping County, and it was about thirty miles away from Wugong County.

"Huh!"

A leading soldier in front of the team stopped his horse and then turned around and came to the side of the prince's special carriage.

"Your Highness, the Maweiyi is ahead. It is about thirty-five miles away from Wugong County. If we continue to travel, it will take another hour and a half. May I ask Your Highness whether you continue to travel, or stay here for one night and leave for Wugong County tomorrow?"

After Maweiyi, there is no place to stay behind, so the leader asked the prince in advance.

This time, Li Chengqian and Su Yan left the palace to visit their relatives, following the formal etiquette. Security and entourage and accommodation were planned in advance.

Li Chengqian looked at his watch. If he continued on his way, he might not reach Su Yan's house until eight o'clock in the evening.

"Su Yan, do you think we should continue on our way or..." Li Chengqian gave the decision to Su Yan.

"It's up to my husband!" Su Yan smiled gently, thought for a moment and suggested: "For safety reasons, Your Highness,Let's stay overnight and continue on our way tomorrow, okay?"

"Okay! I thought so too!" Li Chengqian nodded with a smile.

Then, he lifted the curtain of the carriage and ordered the visitor: "Stay overnight and continue on our way tomorrow!"

"Yes, sir!"

The leading soldier clasped his fists and saluted, turned his horse and raised his whip to issue an order: "Ahead..."

"Your Highness, there is a situation!"

The leading guard shouted, "Be alert!"

The accompanying guards drew their swords from near and far, and they dispersed to both sides of the road to prepare for battle.

The archers at the front squatted down, ready to go.

"Don't panic! General Zhao, find out the truth first!" Li Chengqian's loud voice came from the prince's carriage. He didn't believe that a large-scale enemy could enter the important area of ​​​​the capital without being discovered.

"Yes, sir! Please don't get off the carriage, Your Highness. There is a group of hundreds of people heading this way. I will go and investigate. "The leading soldier returned to the side of the carriage and gave instructions, then rode to the front of the team.

"Keep alert! Go!"

The leading soldier led fifty vanguard troops to meet the crowd on the opposite side, drew his sword and shouted loudly:

"Who is coming?"

No one responded on the opposite side, Wu Tuo looked at Atana.

Atana was about to get off the horse and answer, but heard a shout from behind:

"Zhao Tou, it's us!"

The one who ran out to speak was the East Palace guard assigned to Atana by Li Chengqian.

"Hahaha, Xiao Liuzi, it's you guys! "The leading soldier put away his sword and laughed.

The leading soldier who accompanied Li Chengqian on this trip was named Zhao Dakai, and he was the general of the Eastern Palace. People who had a good relationship with him generally called him Zhaotou.

He was honest and open-minded.

"Zhaotou, is the Crown Prince in front of us?" Xiao Liuzi came to Zhao Dakai and asked.

Zhao Dakai glanced at Wutuo and Atana and others on the opposite side and nodded.

"Please let Zhaotou know that the two are the Western Regions envoys and Atana." Xiao Liuzi didn't say much else, only mentioned Wutuo and Atana.

"Okay, Xiao Liuzi, come with me to meet the Crown Prince!"

Zhao Dakai nodded, reined in his horse and turned around to run towards Li Chengqian's carriage.

"Okay, Zhaotou!"

Xiao Liuzi followed immediately.

"We are all on the same side, stop! "Zhao Dakai came to the front of the team and ordered.

The guards immediately withdrew their troops.

"Your Highness, the guards in front are the guards of the Eastern Palace sent by Your Highness to the Western Regions, and they are returning to Chang'an from the Western Regions." Zhao Dakai came to the side of the prince's carriage and reported respectfully.

After Zhao Dakai finished speaking, he signaled Xiao Liuzi with his eyes.

"Your Highness, Xiao Liuzi, pays homage to Your Highness!" Xiao Liuzi understood and bowed loudly.

"Great!"

After a while, Li Chengqian helped Su Yan get off the carriage.

"Su Yan, I will take you to see the cattle and sheep in the Western Regions that Su Chen has been thinking about."

"General Zhao, follow me to see it."

Li Chengqian did not forget that Atana brought back a thousand cattle and sheep from the Western Regions to Chang'an.

"I obey your command!"
