The advent of glass has played a huge role in promoting the invention of many things in history, and mirrors are just one of the most inconspicuous applications.

Moreover, the glass greenhouse in the East Palace and the utensils used by Li Chengqian to prepare chemical materials have all used glass, and it is believed that in the near future, more different styles of glass will be manufactured and will have a wider range of uses.

With the participation of the Persian who could write Chinese characters, the transparent glass was quickly made, and the bubbles inside began to become less and less.

But with the continuous experimentation, there are more and more glass with bubbles, and slowly a large pile of semi-waste products is stored in the warehouse.

And Li Chengqian naturally would not let these things be left like that, thinking about it, he felt that the glass greenhouse had no special requirements for glass anyway, so he simply began to replace the original ground glass one by one, so as to ensure excellent light transmittance of the glass greenhouse.

After Li Er learned that the mirror was made of glass, he also began to show his concern for the glass workshop, and he would visit it from time to time, and when he saw the glass full of bubbles or variegated color, he would let out a sigh of regret.

Changle and Kong Wen also got a dresser with a small mirror, and they almost hugged Li Chengqian and kissed them.

And Xiao Wu and Cheng Xiaosi, who didn't get the small mirror, didn't open the sun for three days, and they kept sulking depressedly, until Li Chengqian used some leftovers to get one for the two of them, and then shouted happily: "Thank you, brother prince!" ”

The days passed little by little, and it was as plain as a glass of warm water.

As the Chinese New Year's Eve gradually approached, the envoys and important ministers of the Western Regions had rushed to Chang'an, intending to take the opportunity of the Tang Dynasty's complete victory over the ****** to express their submission to Li Er and respect the Tang Dynasty as the 'Heavenly Khan'.

Among the envoys of various countries, the most widely circulated is the rumor of immortal wine.

The people of Huawai are addicted to alcohol, and the Tubo, Xue Yantuo, Tiele, Uighurs, Zhaowu Jiu, Khitan and other races with difficult living conditions are simply no wine and no joy.

This caused that before Chinese New Year's Eve arrived, the boxes in the welcome building had already been booked, and they were booked late, and there was no even a box when they were booked.

At this time, Li Chengqian was honestly shrunk in the palace, and he didn't step out of the door, looking like a lady.

There's no way, it's too chaotic outside now, there are all kinds of characters with grimaces, go out at this time, if you are killed by a crossbow arrow flying from somewhere, then it's called wrong.

For a day or two, time continued to fly, and every Chinese New Year's Eve, Li Chengqian made another astonishing move.

A whole basket of verdant cucumbers, with thorny top flowers, was carried into the Taiji Hall when the ministers were dumbfounded.

"Well, that's not true, is it?"

"How could it be a fresh cucumber?"

"Lao Cheng, you pinch me and see if I'm dreaming!"

A basket of newly picked cucumbers in the cold sky shocked everyone in the hall, and countless people were expressing their feelings, and their eyes looking at Li Chengqian were full of horror.

Li Er's nerves, which had been tempered by Li Chengqian, also trembled fiercely, looking at the snowflakes floating outside the main hall, and then at his son, did he really want to confirm the reputation of the immortal disciple?

It is true that there are some greens saved in autumn in the palace, but they are only preserved, and there is no comparison with the newly picked ones.

Therefore, a basket of fresh cucumbers in the cold winter is completely beyond the comprehension of Li Er and the ministers, and those foreign envoys who were invited have already quietly discussed the legends below.

"Father Emperor, today is Chinese New Year's Eve, the children have no gifts, only a small heart!" Endured the vanity in his heart, Li Chengqian bowed to the old man.

"Hmm!" Li Eryu was immersed in shock and did not come back to his senses.

The corners of the eldest grandson's mouth twitched, and she was speechless for a long time.

The small mirror more than a month ago had already startled her and the old man, but after knowing that it was made of special glass, she found that it was the case, and it was still within the understandable range.

But what's the deal with cucumbers in winter? What can be explained with something? This is completely counterintuitive. Because as long as you are a person, you will know that the winter in Chang'an is not long, and all the greens will be killed by the cold weather, and there will be no exceptions.

There are indeed vegetables in the south now, but if they are transported from the south to Chang'an, it will definitely not work without ten days and half a month, that is, any vegetables will wilt when they arrive in Chang'an, and they will never be so fresh.

"Sit down!" After a long time, Li Er shook his head, came back to his senses, and quietly arranged for Li Chengqian to find a place to sit.

Then he personally came to the bottom of the imperial steps, took out a cucumber from the basket, looked at it carefully, and at the same time plucked the small yellow flowers on it, and put it in his mouth to take a bite.

There was a crisp sound of "click", and the unique fragrance of cucumber entered the lungs through the nose, making Lao Li show a comfortable expression while chewing.

Then, Li Er took a few more from the basket, returned to the top of the imperial steps, and handed them to Empress Changsun.

"Your Majesty, is that a cucumber?" The sound of a broken gong sounded among the ministers, and they didn't need to ask to know that it was the old thing of Cheng Fairy.

"Yes!" Li Er nodded.

"That'...... Is it delicious? Lao Cheng swallowed a mouthful of saliva and asked a little tangled.

"It's delicious!" Li Er continued to nod.

"I want to try it too!" Lao Cheng snorted and smacked his lips, looking like his greedy saliva was about to flow down.

"Yes." Li Er resisted the urge to squirt out the cucumbers in his mouth, and said to the attendant standing aside: "Go and divide the cucumbers in the basket, one for each person, it can be regarded as a reward from His Royal Highness the Prince." ”

"Whoa!" The chamberlain is also greedy, just look at the small basket, it is estimated that it may not be enough for the courtiers or envoys, and he ...... Don't think about it.

"Don't 'swoop', you want to hurry up and send it!" The martial madmen of the Tang Dynasty had already been waiting impatiently, and seeing where the servants were still grinding, they couldn't help but urge. Anyway, there is already an old man like Cheng Fairy in front of him, and it's not a big deal to urge now.

"You go over there first!" Li Er glanced at the eager old Cheng and the old lieutenant Chi, and instructed the inner waiter.

"Uh, Your Majesty......".

"Thank you for your grace!" Unlike the stunned martial madmen, the civil officials expressed their gratitude one after another.

Everyone understands the current situation, if you give it to that group of old killers first, it is estimated that before half of it is distributed, these cucumbers will be all gone.
