Datang: At the beginning, Li Er eavesdropped on his heart

Chapter 173 What a difference!
"My lord, you are finally back. Potassium nitrate, sulfur, charcoal powder and other things have been found. There are also some metals, which are now in the backyard."

"There are also those workers who have already been found, and are just waiting for your lord to give orders."

As soon as the housekeeper saw Li Yin walking in, he immediately spoke.

Hearing this, Li Yin nodded, "You tell them to wait in the backyard first, and the king will come over later."

After returning to the study, Li Yin immediately started to take out the pen and paper, and wrote it out in a hurry. After writing for half an hour, he finally finished writing.

Seeing what he had written, Li Yin picked it up without saying a word, and went straight to the backyard.

At this moment, the housekeeper had already prepared everything, and the workers were all dressed up, waiting for Li Yin's arrival.

"Steward, let them do as above."

Li Yin put a blueprint in the housekeeper's hand. When those people heard this, they gathered around one after another. When they saw what was written on it, they were a little surprised.

"His Royal Highness Liang Wang, why does this thing look a little complicated, we can't understand it."

"Yes, Your Highness King Liang, why don't you explain it to us? In this way, we can avoid mistakes."

.........

Everyone showed a look of doubt, obviously they didn't understand what was on the blueprint.

When Li Yin heard this, he thought that he had already written it on paper, and these people should be able to understand it, but he didn't expect to need to explain it himself, so he sighed and said slowly:
"You guys remember a formula, mononitrate, disulfide, and charcoal. Based on this, add sucrose, good man metal or metal salt, which are available here, and then use..."

Li Yin explained one by one, after the workers heard this, they slowly understood.

Soon the workers started to make it.

It took almost an hour, and the thing was finally made. Li Yin took out a small one and did some experiments. Suddenly, the flames lit up, and there was only a bang, and the courtyard of Prince Liang's Mansion was suddenly illuminated by a burst of colorful light!

After the workers saw this, they were stunned, unbelievable, and each of them showed a look of surprise.

They never thought that this kind of thing could emit such colorful light.

"Hiss! What was the sound just now? Why was it so loud?"

"Look quickly, there seems to be a strange phenomenon in the sky above Prince Liang's Mansion, my God, could it be that there are immortals?"

"I'll go, I've seen it too, His Royal Highness King Liang must have done a lot of good deeds, that's why he attracted immortals!"

.........

After seeing this scene, the surrounding people talked a lot, saying that His Royal Highness King Liang had done too many good deeds, and the immortals began to descend on King Liang's mansion.

Soon, this rumor was spread ten times, ten times to hundreds, and the whole Chang'an City knew about it, and everyone spread it even more miraculously.

Regarding these rumors, the top and bottom of Prince Liang's Mansion were unanimous and kept silent, allowing rumors to spread outside, and they didn't say much.

Soon, the Spring Festival will come as promised.

The entire Chang'an city was unusually lively, the curfew was lifted for this day, every household put on new clothes, and the streets were full of people.

Those selling Kongming lanterns, guessing lantern riddles, and small toys all flooded the streets, and many rich men and ladies also came out.

The common people who took to the streets are also paying New Year's greetings: "Mr. Li, Happy New Year."

"Zhang Yuanwai, happy new year. I haven't seen you for a few days. Zhang Yuanwai is getting healthier."

"Hahaha, Li Yuanwai was joking."

.........

"Sixth Aunt, Happy New Year, my mother asked if you would like to come to my house for dinner."

"Three Gouzi, thank you, tell your mother, I will come tonight."

…………

The city of Chang'an is so lively, and the imperial palace is even more lively.

There were lanterns and festoons everywhere, and Li Shimin and Empress Changsun wore festive clothes and sat on the upper seats, while the Supreme Emperor Li Yuan sat on the upper seats beside him.

Seeing that Li Yuan was able to come out, Li Shimin was very happy, and the other princes and princesses were also very happy when they saw Li Yuan.

After singing and dancing, Li Shimin stood up, and first offered a toast to Li Yuan: "Father, today is the Chinese New Year, a day of great joy. It is a kind of happiness that our family can get together. I toast you a toast. I wish my father good health and all the best."

After saying this, Li Shimin drank it all in one gulp. His bold actions and smiles all showed that Li Shimin was very happy at the moment.

When Li Yuan heard this, he nodded again and again. After all, Li Shimin gave himself face, and immediately finished the wine in his glass.

At this moment, Prince Li Chengqian also stood up, raised his wine glass to Li Yuan, Li Shimin and Empress Changsun, and said with a smile on his face:
"Grandpa, father, queen mother, today is a big festival, and my son and minister have nothing to say, so I will borrow the words of my father, and wish my grandfather, father and queen mother good health and all the best!"

After Li Chengqian said this, he immediately raised his wine glass and drank it down in one gulp.

As His Royal Highness the Crown Prince and the Crown Prince of the country, he was naturally the first to stand up and congratulate. After Li Chengqian drank the glass of wine, it was the turn of the other princes and princesses to toast according to their size.

They picked up their wine glasses one after another and began to congratulate. Basically, the congratulatory messages were almost the same without much difference.

After one round, it actually took half an hour. When it was Li Yin's turn, he substituted tea for wine because he couldn't drink.

However, Li Yuan suddenly said: "My son, come here, come to Gu, the wine here is quite delicious, so don't drink tea all the time, now you are almost nine years old, why don't you drink tea?" He is more or less a little man, how can he drink tea all the time?"

Li Yuan said with a smile, and waved to Li Yin, the sudden behavior shocked all the princes and princesses present!
What the fuck?

isn't it?
Grandpa Huang, whom I haven't seen for several years, is actually so kind to Li Yin?
When the crown prince Li Chengqian was toasting, the Supreme Emperor didn't say a word, so the Supreme Emperor started greeting Li Yin before Li Yin toasted?

hiss!
Think carefully!

With such an obvious difference in treatment, these people are all caught in their eyes, each of them is unbelievable, secretly speculating
And the princes and princesses present are all human beings. After living in the palace for so long, how can they not have the ability to observe words and emotions?
Now they have seen that Li Yuan is taking extra care of Li Yin.

Is there any relationship between these two?
