In these years, tungsten sand trading is an emerging industry, which is basically in a laissez-faire state, no matter who or what foreign firms, you can buy.

It was not until 1927, after the establishment of the Republic of China government, that there would be people in charge, but the management was chaotic and smuggling was rampant.

It stands to reason that Keiko has harmed China's interests by doing this kind of business, but she is not a Japanese spy and does not understand the harm, let alone that there will be a bloody war between China and Japan.

Qin Di didn't bother to care, because the country was too chaotic, even if Keiko didn't do this business, someone else would do it.

Not to mention 1922, even in 1933, the Soviets established a tungsten mining company! 4,193 tons of tungsten sand were mined and purchased, and through Chen Jitang's troops, the blockade was broken through and transported to Guangzhou for export. At that time, 100 catties of tungsten sand were sold for 52 oceans. From 1932 to 1934, the tungsten sand trade earned 6.2 million yuan and fed 100,000 troops.

This is also something that cannot be helped, because the times have changed, the situation is complicated, and no one can see too far.

What's more, at that time, the price of a ton of tungsten sand was equivalent to one million yuan a ton in the 21 st century! In 1994, after the reform and opening up, the price of a ton of tungsten sand was as low as 6,000 yuan! Not only tungsten sand, but also a variety of rare earth raw materials were sold extremely cheaply, which made Qin Di find it difficult to understand.

Qin Di had a lot of funds at this time, even if he collected and stored tungsten ore, there was no problem, but he couldn't see the benefits of it! If he rashly raised the price of tungsten ore, it would inevitably further stimulate mining and thus deplete tungsten ore resources! Therefore, he was too lazy to care.

"Hmph, anyway, it is a beautiful China, a treasure of nature, a lot of land, even if you dig up all the minerals, it's a big deal to wait until the 21st century, and then buy it back after the rejuvenation of the nation!"

This year, Qin Yue was eighteen years old and entered the Faculty of Arts of St. John's University.

Because she was beautiful and young, she quickly became the school flower and attracted the attention of many people.

However, she is the daughter of the great scientist Zhu Wan, and she is followed by bodyguards when she enters and exits the school, and ordinary people dare not provoke her. She went her own way at school, wrote poems at home, and although she didn't publish them, she lived happily.

In the eyes of outsiders, Yan Xue, the "third lady" of the Qin family, has skipped a grade and been promoted to middle school, still fishing for three days and drying nets for two days, and is not a good student who does not follow the rules.

Although she is young, she has an amazing beauty that makes people lose their minds.

There were countless male students following her, and there were even many old men who drooled at her from afar.

However, Qin Di was very relieved of her. Don't look at Yan Xue as just the first layer of qi refining, in this declining world, if you don't use guns, few people are her opponents.

On the morning of July 30, the weather was sunny and hot.

Qin Di left home, came to Ci'an Hall, took a large bag of traditional Chinese medicine, plus the leftover yellow essence he ate, and then went to the basement of the medical research institute. He has a separate office there.

He locked the door and pulled out a strange Dan furnace.

This Dan furnace was brought from the "Jade Void Palace" of Wudang Mountain when he traveled all over the world, it was three feet high, made of red copper, and weighed seventy-two pounds.

At that time, he wrapped the Dan furnace with a coat, carried the Dan furnace for nearly a hundred miles, came to a nearby county town, put the Dan furnace in a wooden box, and found someone to consign it to the magic capital.

At this moment, he took out the Dan furnace, put a charcoal basin underneath, and then continuously threw various medicinal materials into the Dan furnace.

After a whole day of refining, he opened the Dan furnace and looked at it, and couldn't help but be a little disappointed.

With his alchemy strength, it stands to reason that he can get ten top-grade pills when he catches them, but what appears in front of him at this moment is only five inferior pills with dull colors.

He took one and tossed it into his mouth, tasted it, and quickly sighed.

"Alas, there is no way, there is neither spiritual grass nor spiritual fire, and you can't refine a top-grade spiritual elixir! Such an elixir can prolong your life for two or three months at most!"

The next day, at dinner, Qin Di took out the remaining four pills and distributed them to his father, mother, sister and sister.

The four of them stared at the dark cyan pill.

Qin Hancheng asked, "What is this?"

Qin Di replied: "The elixir that prolongs life can restore youthful vitality." ”

"Where did it come from?"

"I made it myself. ”

Zhu Wan asked with concern: "Will it be poisonous?"

Qin Di smiled: "How is it possible?

Qin Ling stared at the pill for a while, and said, "It is said that the Taoists in ancient times liked to take gold, swallow white jade, and refine the pill at every turn. But in the end, I didn't see them become immortals. ”

Qin Di said: "With this kind of inferior elixir, you still want to become an immortal?

Qin Yue pouted and said, "It's so ugly, it's not dark, I don't dare to eat it! Xiaoxue, let it be given to you!"

Yan Xue shook her head with a smile and leaned back.

Qin Di looked at everyone with a smile: "Eat, I finally refined it, based on the essence of plants and trees, it does not contain heavy metals, and it is harmless to eat it." ”

After a while, Zhu Wan took the lead in reaching out, picked up the pill and threw it into her mouth, tasted it, and said, "The taste is a little rushing." ”

Qin Di smiled bitterly: "After all, it is a low-grade elixir, and the heat is not well controlled." ”

Back then, he used spiritual fire and immortal fire in alchemy, where did he use charcoal?

Qin Hancheng hesitated for a long time, and waited until he finished dinner and saw that Zhu Wan was fine, so he swallowed the pill.

Then there was Qin Ling, who swallowed with a frown.

Qin Yue refused to eat anything: "Take it, take it, I don't want it!"

Qin Di said with a smile: "Taking this medicine can make the old man young and the woman beautiful!"

Qin Yue asked, "I don't believe it." Xiaoxue, have you eaten it?"

Yan Xue shook her head: "No." ”

Qin Di said with a smile: "Yan Xue has a special physique, and she can live a long and healthy life without taking medicine." ”

No matter what she said, Qin Yue refused to eat it, she pushed the pill aside, and she didn't want to look at it.

Qin Di had no choice but to put away the pill and said, "It's okay if you don't take the medicine." If you want to live a long and healthy life, facing flowers and green trees every day, keeping your spirit inward, and sinking your dantian, it is also effective. ”

"Brother, what you're saying is too complicated! Everyone has been very busy these days! Who can calm down and cultivate their minds?"

Qin Di shook his head and sighed from his heart.

To be honest, his family members didn't have spiritual roots, so they couldn't embark on the path of immortality.

This is the earth of the last days, the aura is very thin, ordinary people do not have the qualification of the spiritual root, even if they meditate, it is difficult to let the aura enter the body.

Qin Di was the reincarnation of an immortal and once possessed the means to reach the heavens. If there is a special elixir, he can refine the elixir and let those who do not have a spiritual root open the spirit. If he makes great progress in his skills and cultivates into a Yuanying True Monarch, he can also use the talisman to open the spirit to his family. However, he could not do either method.
