The Lone Star of the Tang Dynasty

In the knowledge of the previous life, the formula of the black huo medicine was actually not complicated, which also made it widely circulated, and many people knew a little about it.

But what Li Changge is deploying is not the simple version that is circulated in the market.

He has put a lot of effort into the purification of saltpeter and sulfur, and has carried out accurate mass ratio in strict accordance with the chemical formula, which makes the quality of black HUO medicine far beyond the previous life.

However, Li Changge was not satisfied.

His goal is to create an even more powerful Black Potion, which is its derivative, the Compressed Black Pill. This black medicine is compressed to half the size of the same amount of API. Despite the simple compression, it's twice as dense and as powerful as a staggering four or five times!

But to make this compressed black huo medicine, its formula is completely different from ordinary black huo medicine, and some special materials need to be added.

Moreover, the compression process is also a technical task, and the slightest carelessness can lead to failure.

The consequences of failure can range from a loss of power to an explosion that can cause serious personal injury. This made Li Changge have to act cautiously.

In the process of manufacturing compressed black medicine, Li Changge first tried the configuration of a variety of materials, and finally determined a feasible formula.

This recipe required high-purity iron powder, and although it was extremely difficult to obtain, he managed to obtain a few catties of iron powder by working with the best blacksmiths in the city and forging it around the clock for a month.

In the production process, Li Changge also continuously improved the quality of charcoal, and obtained higher quality charcoal powder through better refining methods.

He carefully adjusted the formula and improved the compression process, and finally succeeded in making more than five catties of compressed black HUO medicine.

On this day, Li Changge was preparing to conduct an experiment with compressed black huo medicine, and happened to meet Lao Liu Tou.

The two exchanged pleasantries and ......

Li Changge was about to step away, looking for a secluded and uninhabited wasteland to test the five catties of black medicine in his hand, but suddenly there was an urgent call behind him.

"Childe, Childe, please stay!".

Li Changge was stunned when he heard this, and turned to look at the source of the voice, "Mian'er, what's going on?"

Since he became a member, the mansion has returned to its original function - to become a place to live.

Although he has recently focused on researching how to compress the black medicine to increase its power, the dangerous items in his hands have been brought out of his hands, and the remaining parts of his home are carefully wrapped in oiled paper and hidden in an abandoned dry well to prevent accidents. Therefore, there are no major matters to deal with at home on weekdays.

Hearing Mian'er so anxious at this moment, Li Changge's heart couldn't help but tighten, guessing whether it was a fire in the house, or the Turks had come to harass and plunder again? He frowned and walked back to Mian'er's side quickly, and Mian'er also panted to meet him.

"What is the matter? Is there a fire in the house? Or are the Turks coming to fight the grass valley again?" Li Changge blurted out, with a hint of anxiety and dissatisfaction in his words.

"No, Childe, you misunderstood! It's Master Li and they're here!" Mian'er said as she smiled like a flower, obviously not a bad thing.

Only then did Li Changge remember that Lao Li had indeed not visited for a while.

Now that a guest has visited, his work on testing the HUO drug can naturally be put on hold for the time being.

So, he nodded slightly and said, "Then let's go back quickly, it just so happens that I haven't seen them for a long time." By the way, I can also take this opportunity to ask them if they know the skilled craftsmen, and help me get some pure iron materials. "

Not long after, Li Changge returned to the door of his house, and saw Lao Li and his party waiting at the door for a long time.

It

is very different from the sad appearance of the last visit, this time Lao Li and the others are all red and smiling, and they are even more happy to see Li Changge, and the joy is overflowing, just like a child's New Year's Day.

When Li Changge saw these familiar faces, he couldn't help but feel a burst of joy in his heart.

In this era when there is no Internet and no sand sculpture netizens to accompany him, he lives in the countryside and focuses on scientific research, except for the company of cotton, he does have few social activities.

It was only then that he deeply understood why the ancients included the phrase "having friends from afar, and being happy" in the Analects.

What surprised Li Changge was that Lao Li and the others were much more excited than themselves, and their faces were filled with uncontrollable joy. He wondered why these people were so happy

"Lao Li, are you here?" Li Changge stepped forward, smiling and greeting him.

"Haha, Childe, long time no see!" Lao Li replied with a smile on his face.

Li Changge quipped: "Do you still know that I haven't seen you for a long time? I haven't seen you recently, and I am happy to be like this when I meet, can I win the jackpot?".

"Hey, you guessed half right!" At this moment, Li Er's smile was like a big chrysanthemum in full bloom, and the joy from the inside out made Li Changge look a little uneasy, and he thought to himself: How can this product look more and more like a human trafficker.

"Come on, let's go into the room and sit down and talk slowly. Li Changge said as he led everyone into the house.

After a while, the group came to the front hall of Li Changge's house and sat down.

As always, Mian'er poured a cup of fruit tea for everyone.

At this time, Li Er asked curiously: "Song...... Oh, Childe, what kind of tea is this, and why does your tea always have a faint fruity aroma?".

This question made Li Changge laugh dumbly, and said in his heart that this old boy only noticed this fruit tea now

It turned out that this fruit tea was made by Li Changge using the fruits purchased around the village and in Youzhou City, dried the fruits, and then skillfully matched with the tea leaves. In later generations, fruit tea has long become a frequent customer in various beverage shops, with a wide variety, but it is unprecedented in the era of Datang.

There

is no black tea in Youzhou, so it is quite limited to make milk tea, so Li Changge figured out this fruit tea, and successfully won the love of Mian'er, and even became his proud work.

"It's fruit tea. Li Changge explained.

"Fruit tea, is this a tea soup?" Li Er was slightly surprised when he heard this, and carefully examined the drink in his hand. Compared with the tea soup he usually drinks, this fruit tea has a sweet and refreshing taste, fragrant and sweet, and after tasting it, he feels that it is indeed far better than ordinary tea soup.

Li Er's exclamation attracted the attention of Du Ruhui, Fang Xuanling and others, every time they accompanied Li Er to visit, they were always full of worry and had no time to care, and at this moment, Li Er reminded them to find that this fruit tea was so delicious, completely surpassing all the tea soups they had tasted before.

Li Changge briefly introduced the production method of fruit tea, focusing on the process of drying dried fruits, and the process of roasting tea is more complicated, from the original original technique to the version that has been improved countless times in later generations, if you talk in detail, it is enough to write a tea classic. However, he expected that these wealthy businessmen in Chang'an might become interested in business opportunities, but unexpectedly, Li Er and the others did not ask about the roasted tea technique, but looked at him with wide eyes, surprised by the new way of eating the fruit.
