The Lone Star of the Tang Dynasty

"The country will not fall in an instant because of a few rebellious ministers and thieves. If you can't find a solution for a while, why not put it aside for a while and give yourself a day of rest? You might as well go and watch the song, feel the warmth of the family, maybe you can change your mood and perspective. "

Although Empress Eldest Sun had comforting meaning in her words, she knew in her heart that Li Er's character would never give up easily.

"Guanyinwen, what did you just say......" Li Er's eyebrows furrowed slightly, eager to capture that moment of inspiration.

Empress Eldest Sun thought for a moment and replied: "What the concubine said is that if Your Majesty is really worried, you might as well put aside government affairs for a while, rest for a day, and visit Ge'er." "

"Exactly!" Li Er became excited, as if he had found the key to solving the dilemma, "You said to go see Ge'er-".

Li Er slapped his thigh suddenly, a long-lost smile bloomed on his face, and he was full of pride.

He turned his head to Wei Zheng, Fang Xuanling and the others and ordered: "A few of you, as well as Li Jing and Li Junxian!

Hearing this unexpected decision, Wei Zheng, Fang Xuanling and other courtiers were all stunned and looked at each other.

They wondered in their hearts: Go to see His Royal Highness King Xian?

Du Ruhui stood on the spot as if he had been struck by lightning.

More than half a month ago, he had proposed to His Majesty to express his condolences to His Royal Highness King Xian, but in retrospect at this moment, he actually ignored the most important point - Li Changge, King Xian, is not only majestic and strategic, but may even be superior to His Majesty in some aspects;

This thought was like the light of dawn, instantly dispelling the long-standing haze over the Manna Temple.

Li Shimin and his important ministers looked at each other and smiled, the laughter was hearty and full of anticipation, as if they had regained the determination and vitality when they went to the battlefield together.

The family problem that everyone in the world is helpless may have a solution to it in His Royal Highness King Xian.

At this moment, it seems that Li Shimin and his loyal ministers, who have been unloading their armor for many years, are in good spirits, and they have returned to the years of the military camp that were full of tacit understanding and action. Everyone couldn't wait to move, almost running to prepare for their own cross-dressing.

Wei Zheng, Fang Xuanling and the others secretly regretted themselves, and scolded their own stupidity: "Why haven't we always remembered that there is a living Bodhisattva like King Xian by our side?

...... at the moment

It is at the turn of spring and summer, in a quiet house on the outskirts of Youzhou.

Li Changge leisurely immersed himself in the scrolls, enjoying this indifferent and healthy life.

Although he is the owner of the farm, he has not neglected to take care of his own shop.

Since the bully, surnamed Choi, was brought to justice and life was peaceful, Li Changge devoted more energy to the affairs of the estate, especially the paper-making project, which has recently made significant progress.

In one corner of the estate, three separate sheds stand majestically, and this is where his small paper workshop stands. Although the scale is not large, the layout of the internal facilities is scientific and reasonable, from raw material boiling to paper drying, everything is available, and it can stably produce five or six hundred catties of high-quality paper every day. This not only brought additional income to the estate, but also provided a livelihood for the surrounding people who had nothing to do in their spare time, allowing them to increase their income, and the joy was palpable.

However, it is now the busy farming season, and the workshop is not yet in full operation, so Li Changge has to wait patiently for the opportunity.

On this afternoon, the sunlight poured into the study through the window lattice......

Li Changge is immersed in the review of the biology course, trying to consolidate the Mendelian laws of inheritance in his memory.

At this time, the intimate maid Mian'er came with exquisite fruit tea and pastries.

"Childe, this is the fruit tea and snacks you want. Mian'er said softly.

Li Changge raised his eyes slightly and responded: "Put it there." "

Just as Li Changge was about to continue his studies, Mian'er inadvertently mentioned something that surprised him: "Childe, when I went to Chang'an to purchase materials a few days ago, I found that more than 500 bottles of perfume prepared at the beginning ......of the month had been sold out."

"What? sold out again?" Li Changge couldn't help but be stunned, he clearly remembered that he had asked Ying'er to grade and sell perfumes, the cheapest experience version was only sold for 200 wen a small bottle, and the top one was priced as high as 100 21 bottles, and the maximum supply was strictly limited to five bottles, ensuring quality and increasing profits. I originally thought that such a strategy would allow the perfume to be slowly digested in the market, but I didn't expect it to be sold out in a short period of time.

Li Changge asked suspiciously whether it was the work of someone who forced to buy and sell.

Mian'er smiled and explained, "It's not like that, Childe. The reason why the perfume is so popular this time is that somehow it actually made its way to the royal palace and was favored by the queen's mother. Now the ladies and ladies of the entire Chang'an City are rushing to buy this perfume one after another. "

"I see, it's the queen mother who brings the goods herself!" Li Changge couldn't cry or laugh, secretly thinking that there was a phenomenon similar to the modern star effect in ancient times. Although the out-of-stock means that some customers will not be able to buy in the short term, in the long run, this kind of hot sale will undoubtedly bring great reputation and business opportunities to the store.

Seeing that the shop was operating normally and thriving, Li Changge decided to return to another of his experimental plans.

"Mian'er, do you remember the chemical practices I told you?" he asked.

"Chemistry, I remember, is Childe going to do something special?" Mian'er replied curiously.

"That's right, what we're going to do today is the basic experiment of 'three acids and two alkalis', come with me to the laboratory!".

The uniqueness of Li Changge's papermaking process lies in the use of strong acids and alkalis in modern chemistry for bleaching.

This crucial step gives the paper a flawless white texture, which is a world of difference from the yellowed and rough so-called famous paper.

Not only that, he also introduced modern technology in the selection and production process of wood pulp, ensuring that the paper is both beautiful and tough, but the most important change is the white as snow effect, which brings an unprecedented visual impact to this era.

However, at present, Li Changge has encountered a bottleneck in the preparation of nitric acid, and only relies on the local good saltpeter soil method to produce, although it has a certain effect, but it cannot meet the needs of large-scale production due to low output.

Therefore, he decided to ask Mian'er to help him explore how to increase the concentration of nitric acid, with the goal of achieving 98% purity.

Although in the modern chemical industry, every link pursues a high degree of purity of raw materials, but fortunately, Li Changge is not limited by this.

Recently, through some mysterious way, he obtained a large amount of sulfuric acid as the initial raw material, which undoubtedly greatly lowered the technical threshold in the initial stage, so that he was able to directly establish a small workshop of "soil method of acid and alkali".

In the eyes of the world, such a "workshop" is actually a high-tech factory that has traveled through time and space.

Just as Li Changge was about to take Mian'er to the backyard to start the experiment, a noise suddenly came from the front hall, breaking the silence of the house.

Li Changge wondered in his heart, he had not heard of any happy events or funerals in the village.

At this time, a familiar voice sounded: "Childe, it's me, Lao Li!"
