People in Datang have been expelled from school

Chapter 699 Worries in the Palace

After burning for more than an hour, Tie Da glanced at the reddened sand and said, "Chang'an Order, it seems to be almost done."

Li Zheng also took a look and said, "Cease fire."

Tie San stopped pulling the bellows, and Tie Er closed the air outlet.

The flame immediately weakened.

Tie Da used iron tongs to remove a bowl of sand above the stove.

The sand was all red. When Li Zheng pushed the sand away, he found a lot of crystals.

Carefully remove these crystals for observation.

These crystals are pale white and are very suitable for making clear glass.

Li Zheng pointed to a cart of sand outside and said, "Burn all the sand in this cart."

Tie Da waved his hand and asked Tie Er and Tie San to work.

Li Zheng instructed again: "Wear a mask, if you don't wear a mask, you are not allowed to work."

"understood."

Tie Da nodded very seriously.

After firing these crystals, sort them all out and put them together.

It doesn't take much, a small jar of crystals is enough, and then these crystals are put together and fired.

It is fired into a gel, ready to be shaped and sanded before cooling and setting.

After getting the raw material of sand, the subsequent things became much easier.

There are records about eyes from the Ming Dynasty.

At that time, the eyes were not so clear.

Not enough and totally enough.

At that time, the monocle was the most used.

There are also classifications for reading glasses and myopia glasses.

It will take some time to burn the sand, and Li Zheng is sitting in the blacksmith's shop and starting to make molds for polishing lenses.

For several days in a row, Li Zheng almost lived in the blacksmith shop, and only went home at night.

Most of the time is not busy in the blacksmith shop.

Just tinkering in the lab.

From time to time, there will be strange movements in this laboratory.

There are even will-o'-the-wisps in the middle of the night.

Let the villagers dare not test the laboratory.

I always feel that Li is researching something very weird.

Daniel is almost in retreat these days.

Rarely play with children.

He has been in retreat all the time, except for the necessary eating and sleeping time, Daniel is almost reading.

Li Zheng came out of the laboratory in disgrace.

Daniel is still reading with Li Zhi in his study.

"The teacher is back."

"Ah."

Li Zheng feebly agreed, and asked Xu Hui to prepare a change of clothes.

After taking a shower, I lay down on the bed and fell asleep.

Don't care about Daniel and Li Zhi reading.

He fell asleep in the study.

In the bedroom upstairs, Li Lizhi took care of her little son and had already fallen asleep.

Xu Hui came over and said, "Your Highness, the son-in-law has already fallen asleep."

Li Lizhi looked at the little Sizi who was breathing steadily, tidied up her bun and said, "He seems to be quite busy these days."

Xu Hui combed Li Lizhi's hair and said, "Chang'an Ling is really busy in the village these days, and it's weird."

Li Lizhi said, "Strange?"

"Correct."

Xu Hui said in a low voice: "I heard from people in the village that there is a room called the laboratory newly built by the son-in-law, and there will be some strange movements from time to time."

"Strange movement."

"En!" Xu Hui nodded vigorously, "For example, at night, there are some will-o'-the-wisps coming out of the laboratory, and sometimes a lot of pungent thick smoke will come out of the laboratory, and some people can see that Chang'an Ling is making will-o'-the-wisps."

Li Lizhi looked out the window, the village was very quiet at night.

The wind outside the window was a bit cold, so Xu Hui closed the window.

What happened in Jingyang naturally cannot escape Li Shimin's eyes.

Li Shimin looked at the secret report delivered by Wang Ding, "Li Zheng is burning sand these days?"

Wang Ding nodded.

Li Shimin looked at the records on the secret report, "Is there still will-o'-the-wisps? Pungent smoke?"

Wang Ding said in a low voice: "Our people have been staring at Li Zheng, and Li Jiangshan is also staring at him. After a while, we should be able to find out what Chang'an Ling is doing?"

"Wildfire? Can this thing be made?"

Li Shimin frowned and thought.

Wang Ding said: "It's really unbelievable, but Chang'an Ling's ability is very high, and he often does things that others can't understand."

Li Shimin nodded and said: "Let people keep watching, and let me know the result."

Glancing at the night, Wang Ding said in a low voice, "It's getting late, Your Majesty, should I go back?"

"Is there any recent battle report from Tubo?"

Knowing that Li Shimin asked about Tubo's battle report, he was actually asking about His Royal Highness the King of Shu.

Wang Ding replied: "There are indeed battle reports from Tubo, but now Tubo is coming to the monsoon season again, if there is news about this season, it will not be sent out for a while."

Speaking of which, Li Shimin still cares about Li Ke, king of Shu.

After all, he is also his own son.

Shu Wang Li Ke went deep alone like this.

Today's Tubo is so chaotic, it will always be worrying if there is no news for a long time.

A court lady came to report and said: "Your Majesty, the queen said that she is not feeling well tonight."

Li Shimin nodded, "I understand."

"Here."

The maid nodded and left with small steps.

Wang Ding murmured, "Empress Qian has been in good health for an hour, so how could she be unwell?"

Of course Li Shimin knew what his queen meant.

Li Ke's life and death in Tubo are unpredictable now, and there is no news after so long this time.

There must be worries.

The queen is also concerned about Concubine Yang's feelings.

Concubine Yang was the princess of the former Sui Dynasty. After the death of the former Sui Dynasty, she was considered to have no relatives.

The only person closest to and most concerned about was her own son.

If something happened to her son, she would not survive.

Li Shimin stood up and said, "Wang Ding, go and make arrangements, I will go to Concubine Yang's palace tonight."

"Here."

To the west of Chang'an, across Longyou is the windy Hexi Corridor.

The strong wind swept the yellow sand all over the sky.

In the territory of Tubo.

Li Ke and Wang Xuance took people to hide in a cave to avoid the wind.

1000 people crammed into a cave.

The cave is very quiet. This is the lee vent, and the northwest wind cannot blow into the cave.

Many people in the cave have already fallen asleep.

A fire was burning in the cave.

It was warm in the cave.

Before taking advantage of the wind and sand getting bigger, the team ran all the way, and then ran to the cave to avoid the wind and sand.

If it wasn't for running fast, everyone might be buried in the yellow sand.

The weather in the desert is very bad.

This is how everyone feels.

In the face of nature, even an army of tens of thousands is no match for such a strong wind.

Wang Xuance counted the number of people and said to Li Ke: "His Royal Highness, there are not too many people, they are all here."

Li Ke nodded reassuringly, "You can also rest for a while."

Wang Xuance took out a roll of cloth and drew a map on the cloth, "I will also record the route map, so that I can use it when I march into Tubo."

Li Ke scooped out a bowl of boiling water from the pot and handed it to Wang Xuance, "Take a sip."

"Thank you."

Wang Xuance took a sip of hot water and felt much more comfortable.

The howling of the strong wind outside is getting louder and louder, and the sky is covered by yellow sand all over the sky.
