It sounds ridiculous to go thousands of miles away to find a desert, but in Xiong Jing's opinion, it is much more reliable than building a blind man in this way. The crystallization method provides a very important premise for obtaining mixed salts with 64.17% of potassium nitrate, that is, the potassium nitrate in the solution must be saturated, and the saturation cools to 20 degrees before 215 grams of potassium nitrate can be precipitated, but what if it is not saturated?

Xiong Jing doesn't remember the latitude and longitude of the Atacama Desert, but he knows that there seems to be only one harbor (Perto Antofagasta) in the narrow coast of Chile, and saltpeter is transported from the inland desert east of the harbor.

The Atacama Desert is caused by the Andes that block the warm and humid air mass of the eastern Amazon Basin, and to the west is the Antarctic cold current that does not rain, so it has become one of the driest areas in the world, and it rains every few hundred years. The desert is located between the Andes and the Pacific Ocean, with a narrow shape, a long, 1,100 kilometers long and a wide range of about 100 kilometers.

Even without the guidance of the crescent-shaped port of Antofagasta, the narrow desert, which is more than 1,000 kilometers long, is itself a good geographical coordinate. The desert is the junction of the Three Kingdoms. Since it is called Chilean saltpeter, it must be in the south of the desert.

Finding saltpeter with a sodium nitrate content of 95 in the desert is definitely faster than improving the purification technology than Zaofu. Although it is expensive to obtain saltpeter in this way, when sulfur cannot be obtained, using Chilean saltpeter can triple the gunpowder stock--

All the made gunpowder is dissolved in water, because sulfur and charcoal are insoluble in water, and can be separated from the gunpowder immediately. Then seal and heat the water-insoluble sulfur charcoal mixture, and the sulfur can be separated out in part. The separated sulfur is matched with high-purity Chilean saltpeter. The artillery charge no longer requires four times, so it is only possible to charge normally.

Now the Chu army's infantry and sea armies have more than 500 tons of gunpowder, and when they are transported back to Chilean saltpeter, there may be 400 tons left. If the artillery is loaded normally, the savings in use are equivalent to an additional 1,200 tons of inferior gunpowder with four times the charge, which is equivalent to the 120 tons of sulfur transported back by Hu Dansao, which is worth 30 million drachmas. Thirty million drachmas are enough to pay all the price.

Xiong Jing was silent for a long time, Zhuang Wudi, and Nao Xin and the others were silent and did not dare to disturb him. He was not thinking about the transaction with the Qin people, but thinking about how to increase the stock of gunpowder in his hands and obtain high-quality saltpeter with normal charges. Both are very important, especially the latter. If all saltpeter is transported from overseas, no one can break the secret of gunpowder.

"Chang Jiang," imagined that Xiong Jing called Chang Jiang. Chang Jiang knew what he wanted and quickly presented his notepad. After writing "The Yue people should not go to explore saltpeter" on the notepad, Xiong Jing continued the previous topic.

"Who should I send to Qin?" After writing, the notepad was presented by Chang Jiang again.

"I think Bai Yi is the most suitable." Zhuang Wudidao. After saying that, he added: "Yizan is OK."

"Oh?" Xiong Jing was no longer short of money since overseas trade. The continuous inflow of gold and silver caused slight inflation in the four countries. Fortunately, gold and silver were suitable for storage, and prices rose, but did not soar. Against this background, big merchants such as Bai Yi were gradually forgotten by Xiong Jing. "Let's choose Bai Yi." He decided.

Bai Yi's ancestors were doctors and nobles, and Yizan was just a big businessman and was still lending usury. Xiong Jing naturally chose Bai Yi. Xiong Jing's choice was also the choice of Zhuang Wudi, and he also thought Bai Yi was more suitable.

"I will go to Bai Yi to see Bai Yi today." Zhuang Wudi's eyes blinked slightly. The wedding date is December. If the transaction can be completed in December, and if Mi Ren suddenly appears in Ji Ying on the wedding day, the queen will definitely cry with joy.

"Good." Zhuang Wudi's subtle expression did not hide from Xiong Jing's eyes, but he pretended not to see it. In his heart, Mi Ren's father-in-law was not as important as he wanted to exchange for artillery. He just wanted to exchange Xiong Qi's corpse and his children who were punished as ghost hunters to become slaves.

"Report to the King," Zhuang Wudi and Nao Xin retreated, and Chang Jiang came to bow with a jade pendant. "Wei girl Gongsun Yan asked for a meeting."

"Gongsun Yan?" Xiong Jing had forgotten who Gongsun Yan was.

"King, the alliance was not completed that year, and Gongsun Yan returned to the scouts of the Qin people. The king left this jade pendant and said he would report it to him in the future." Chang Jiang reminded that he remembered Gongsun Yan.

"It's her." Xiong Jing remembered that the King of Wei once mentioned that he would send Gongsun Yan to be a concubine, but he did not agree. "What's wrong with her..."

"He held this jade pendant and asked to see the king, and told him about something important." Chang Jiang replied.

"Summon, summon her to the court." For the king, time is very precious, so he must separate power. Xiong Jing did not want to summon Gongsun Yan, but Gongsun Yan had to be kind to him after all, so he could only let go of everything and summon him.

Gongsun Yan is about the same age as Mi Xuan, but has never been married. To be honest, Gongsun Yan is not unbeautiful, but she has no characteristics, so her appearance always makes Xiong Jing unable to remember. Under the guidance of the envoy, Gongsun Yan appeared in front of him. He just looked at it, then stopped looking at it, and said, "Why did you come?"

The men's clothes are different in color, but the women require that the clothes are not different in color, and the clothes are the same color, and are connected to the top and bottom. Gongsun Yan is wearing a curved hem robe that shows her waist, wearing a dome hat, and holding a Chu paper fan instead of a stool fan in her hand. The so-called stool fan means that when you meet an acquaintance on the road, you can use stool fan to cover your face to avoid it.

Quyou is blue, with plain belt, and carefully dressed up her face, with white face and red lips. As soon as she left the shore, a disciple shouted to follow her on the way. Some cars and drivers came over to ask the female son where she wanted to go. He heard that Gongsun Yan was heading to the Royal Palace in the North City, and everyone retreated. The men and women all turned back to each other along the way, but Xiong Jing just looked at her quickly, and Gongsun Yan's heart couldn't help but be a little gloomy.

"Report to the king, I heard that there is..." As he spoke, Xiong Jing looked at the document on the desk and did not look at her. Thinking that he was almost reporting to Queen Mi Xuan, Gongsun Yan couldn't help but bit her lips.

"What's the matter?" Xiong Jing saw her pause and glanced at her. Her bright red and thick lips were biting in her mouth. At this time, he realized that Gongsun Yan was not ugly, at least her lips were a little sexy. He lowered his voice and said, "You have not married yet, can you be the mother of Princess Wei?"

It is very rare for a woman to marry over 20 years old. Thinking that it might be that he delayed Gongsun Yan in Sangsun, Xiong Jing gave her a chance to marry into the Chu Palace. He didn't want to have too many wives and concubines, he even had a bold idea: besides Mi Xuan, there were a few other women he liked, the rest were artificial insemination to save trouble.

Xiong Jing's problem shocked Gongsun Yan, but the word "媺" deeply stimulated her. A woman who can calmly retreat to the Qin army scouts, a woman who can run around alone for several months, thinks she is a little proud of her high school. Xiong Jing can't give her a title, but she cannot let her rely on others and become someone else's mother.

He bit his lip again, and Gongsun Yan said, "I don't want to. I'm asking for the king today, but because I heard about it, Young Master Mi wants to murder the king."

"Mr. Mi?" Xiong Jing was surprised and moved in an instant. For some reason, this move made Gongsun Yan happy. "Mi Xuan?"

"That's right." Gongsun Yan bowed again. "I heard that Qin and Rong Zhai are the same customs as tigers and wolves, greedy, violent, profit-loving, and have no faith, and do not know etiquette, morality and virtue. Therefore, they all use their families as their qualities. Although the young master Mi is in Chu, his family is in Qin..."

"Who says that all the families are in Qin?" Xiong Jing interrupted unhappily and shouted: "Buling attacked Guanzhong and pulled out Xianyang, and brought his family back to Chu!"

"I know, but the father of Mi Nu is still in Qin." Xiong Jing attacked Guanzhong, pulled out Xianyang, and took back the Mi clan. All these things were published in the news about Chu, but Mi Ren and Xiong Qi, the prime minister of Qin, met with Mi Xuan through Shangcai, and Gongsun Yan was also very clear about this.

When she answered like this, Xiong Jing saw that she had another look. He didn't quite understand what Gongsun Yan was going to report Mi Xuan. Could it be that she was a spy from Qin and wanted to provoke her relationship with Mi Xuan? But why did she cover herself up back then?

Xiong Jing was suspicious, and Gongsun Yan continued: "In May, the young master Mi and his father met in Shangcai. The palace in Shangcai was simple. My maid occasionally heard his father's words and asked him to kill the king. Otherwise, the Qin people would punish the entire Mi clan, and the young master Mi responded to it."

"It's impossible!" Xiong Jing was furious. He glared at Gongsun Yan, as if he was going to kill her.

"The king does not believe me, so I can summon my maid to ask me." Gongsun Yan was not afraid of Xiong Jing's anger. "The king loved Mi Nu and Young Master very much. However, the Mi clan had rebelled against Chu for a long time, and he was already a Qin man rather than a Chu man. In the world today, if it is not Chu, it cannot resist the violent Qin man. The safety of the king is related to the survival of the world. I risk my life and death today, which is for the sake of the world!"

"The world?!" Xiong Jing was powerless. He heard that 'Men Mi's son was stabbed in his promise', and his wound was dripping with blood. He loved Mi Xuan, but Mi Xuan really loved him? Xiong Qi arranged for her to return to Chu and she would not return, and she was not happy to enter the Chu Palace.

Yes, he can indeed exchange Mi Ren, but so what? In the story of Zheng Bo killing Ji Zhong, Yong Ji asked her mother, and her mother said, "It's just a husband, but Hu Kebi?" There is only one father. Which man in the world cannot be a husband, how can he compare?! If she didn't rob her back, she would be very happy to be the good man of the King of Qin, right?

Love is so deep that his beloved woman wanted to kill him for the sake of his family. Xiong Jing was not only weak, but even his breathing was suppressed. He took several breaths before taking a deep breath.

"King, I'm..." Gongsun Yan looked at Xiong Jingyou's anger and her eyes turned dim. The little bit of joy before disappeared, she wanted to hug the man in front of her, but she couldn't.

"Come here!" Xiong Jing had no smile on his face, only the indescribable coldness. Chang Jiang came in quickly. "Zhao Naoxin, leave Gongsundaughter, Prince and her maid behind."
