Qin Di knew what he wanted and didn't care about other people's opinions.

For him, the most important thing is his body. He basked in the sun every day, absorbed the essence of the sun and the moon, and kept his spirit inward, breathing and breathing, and occasionally he could barely absorb a trace of pitiful spiritual energy from the barren air. After accumulating this for seven or eight years, he finally refined a breath of true energy. This true energy was used on his fingers to poke a hole in a half-inch-thick wooden board. However, he accumulated too little true energy and could not cover the entire fist, let alone cover an arm.

Those who practice martial arts practice breath internally and externally.

Those ordinary martial artists will never be able to refine true energy for a lifetime.

Qin Di does not need to practice boxing like others. He practices the internal cultivation of immortals. He needs to use true energy to open up the twelve meridians and eight extraordinary meridians, and then gather in the dantian to complete the process of foundation building, and then condense the golden elixir. Unfortunately, the spiritual energy in this world is scarce, and I don’t know that I have to wait until the year of the monkey and the month of the horse to gain something.

He had already clearly realized that if he wanted to improve his skills, it was not enough to just bask in the sun. He needed to travel all over the famous mountains and rivers to see if there was spiritual energy elsewhere. But he was only eight years old, so where could he go? There were no mountains around the Demon City, and a Sheshan Mountain was only 98 meters. Can it be called a famous mountains and rivers?

So he had to go to Ci'an Hall, open one drawer after another, and examine the herbs.

He found that some herbs also had a faint trace of spiritual energy, such as ginseng, Ganoderma lucidum, astragalus, Polygonatum, etc., but these things are of great value. As a child, he had no reason to get a lot of medicine from Ci'an Hall at will.

"It seems that I need to make some money, and it's hard to move without money!"

At this time, my sister Qin Ling was already ten years old and was in elementary school. My sister Qin Yue was weak and sick, and she often had a fever.

Although his mother Zhu Wan is a doctor, whenever her daughter has a fever, there is no good way to do it except physically cool down.

On this day, she received a small amount of white pills from the missionary Tracy of St. Joseph's Cathedral.

She gave Qin Yue a pill, and Qin Yue quickly subsided her fever.

She squeezed the bottle of medicine tightly and couldn't help but praise: "Tsk tsk, it's really a good thing."

Qin Di glanced at it, showed an excited look, and asked, "Is this aspirin?"

Zhu Wan suddenly turned around and looked at him and said, "A Di, do you know this thing? Which book did you see it?"

Qin Di didn't say anything because he couldn't find the original work. Although there were already medical journals in this year, he rarely traveled across the ocean to send it to the Demon City.

Zhu Wan didn't expect her son to answer, so she continued: "You are right. This is aspirin produced by Bayer in Germany. Because of its limited production, it has not been sold to China. It took me 200 oceans to get such a little."

Qin Di knew that aspirin can be regarded as one of the three major magical medicines in the history of medical science. It was successfully developed in Germany in 1897, and was formed in 1899, and it will not be officially sold to China after 1930. In other words, this is a magical medicine for making money. If it can be developed, you don’t have to worry about capital.

So he thought for a moment, gritted his teeth, and said resolutely: "Mom, this medicine is actually very simple, we can make it ourselves!"

Zhu Wan widened her eyes and said, "What? You said you made it yourself? Do you know the specific method?"

Qin Di smiled and said, "I really know.

Zhu Wan said: "How can you know? Even if you know, they have patents! We can't make it casually, otherwise we will have to sue."

Qin Di snorted: "As the saying goes, 'The sky is high and the emperor is far away'. It is a German company that can control my Qing Dynasty?"

Zhu Wan said: "Why can't you control it? Don't forget, we are in the concession! We adopt British and American laws."

Qin Di explained: "Mom, don't worry, we can bypass patents! I heard that there are eight ways to make aspirin. The Germans used one of them, and we can use another method, even if we apply for a patent."

Zhu Wan was so angry that she was so angry that she was so angry that she was completely confused. She took a deep breath: "A Di, aren't you joking? Can this life-saving drug be created by ourselves alone?"

As a surgeon, the most headaches are infections and fevers. If the fever can be curbed, it would be a great fortune! Therefore, the first thing she thought of was to benefit the patients, and she did not think about how much money she could make.

Since Qin Di opened his mouth, he didn't want to hide it anymore. Anyway, he was obedient to his mother and was not afraid of being caught by others and was studied: "If you want to make aspirin, you need salicylic acid and acetic anhydride, and there is also a catalyst. The Germans use concentrated sulfuric acid as catalysts, which not only has low yields, but also relatively dangerous. We can switch to citric acid."

Zhu Wan was even more surprised when she heard a series of chemical nouns.

She knew salicylic acid. Early doctors knew from the fifth century that there was a bitter substance in willow bark that could be used to cool down, but because it was too acidic, it was not a good antipyretic.

She had never heard of acetic anhydride, she had only heard of acetic acid: "Tell me, what is acetic anhydride?"

Qin Di explained: "Acetic acid can be cracked at high temperature and absorbed with ethylene to obtain acetic anhydride. It is a colorless liquid."

"What about citric acid? We can't buy many lemons here."

"Citrate can be prepared by fermenting starch."

After hearing this, Zhu Wan was stunned for a while.

She couldn't even get any of these things. Although she knew that her son was unusual, she could not have imagined that it was so magical.

She thought to herself: "If I could really make aspirin, my son would be an angel! Could it be that he was sent by the Father of Heaven to reveal the world?" At this moment, she even felt that light was shining on her head, and Venus was emerging in both eyes, as if it was somewhat similar to the Virgin Mary.

Qin Di couldn't wait to say these strange words, hoping to earn more money before the troubled times come, collect rare spiritual energy in the world, and strive to complete the foundation building in his lifetime! As long as the foundation building is completed, he can live hundreds of years! Cultivation needs to be as early as possible, the younger the better, and the later the difficulty is.

It is precisely because of this that he did not do anything and said shocking words.

Otherwise, if he waited until he was eighteen years old, he would miss the best age for hair removal and marrow cleaning, and his achievements in this life would be very limited.

Since you are an extraordinary person, you should do extraordinary things!

Therefore, he strongly encouraged his mother: "Mom, take out your private money and then go to grandpa for help. We can make aspirin!"

Before Zhu Wan came to her senses, she asked in confusion: "How much does it cost?"

Qin Di said: "The two thousand silver dollars are almost the same. I need to ask someone to do some experiments."

"Ah? Who can I ask for an experiment?"

"I heard that Fudan Public School has a School of Literature, School of Science and Business, and my grandfather can find several people in the School of Science and extract salicylic acid, acetic anhydride and citric acid separately. I have specific methods, just repeat them."

After a long pause, Zhu Wan woke up and said, "Ah... My Adi is an angel! Only angels do this!"

She calmed down, thought for a while, and said, "Since that's the case, there's no need to do the preliminary experiment. I'll go to a foreign company to ask if I can buy some materials from Europe."

Qin Di said: "This is the basis of industry. It is inevitable, and it must be done sooner or later."

Zhu Wan said softly: "A Di, we have limited funds and cannot put the stall too big."

Qin Di thought about it and agreed.

Because even if the experiment goes well, it will cost a lot of money to build a factory, start a company, and purify raw materials on a large scale. It is hard for a good cook to cook without rice. Without enough funds, nothing can be done.
