There is a peak-like icon on the map, but unlike ordinary peaks, there are several curves on it.

"This place is a volcano, it is useless, and it often smokes. I marked it for the convenience of identification, using it as a coordinate point!" Qin Manwu said.

"Volcanoes often smoke!" Jiang Xingchen's eyes lit up when he heard this, and a documentary I had watched in his previous life was replayed in his mind, which was about the hardships of Indonesian workers collecting sulfur mines!

"Sulphur, good stuff! I remember that rubber seems to be able to be used. In addition, if you get a phosphate ore in the future, you should also use it. And in the future, this thing can also be used for sulfuric acid... Find it a little far from the volcano. Maybe there are hot springs, and you can make money by setting up a hot spring or traveling..."

The more I thought about it, Jiang Xingchenyue was moved, and the corners of her mouth curled up. She lit up the location of the volcano and said, "Give me this volcano?"

"What?" Qin Manwu and Jun Bumi were stunned and looked at Jiang Xingchen in surprise. They wanted to put a valuable mine, so why did they want a useless volcano?

"Jiang Xingchen, you don't have to be polite to us. This is my father's reward for solving the drought in the Qin Dynasty..." Qin Manwu immediately persuaded her. In her opinion, Jiang Xingchen didn't want to accept gifts and deliberately shirked her. She didn't expect that Jiang Xingchen really valued volcanoes.

Qin Manwu has been worried about gains and losses these days. The business in the desert was interrupted due to the war. Not only did he suffer huge losses, but he even more so in Jiang Xingchen. He was lost in at least a few hundred million a year.

Of course, there is no need to worry about no buyers in tea, spirits, and honey. What she is worried about is whether Jiang Xingchen will give all the quotas to the Wang family in the future and sell them directly overseas. After all, the price in the Nanhuang area will definitely not be sold at Shahai.

Not only Qin Manwu, the old man was also a little surprised. He didn't think Jiang Xingchen refused in disguise. This kid accepted Yueying's cold iron ore. How could he not accept the gift from Daqin?

What he was surprised was what Jiang Xingchen wanted to do with a volcano. Based on his understanding of this kid, this volcano must have a useful function.

"Boy, is there something you need in this volcano?" the old man asked casually.

Qin Manwu and Jun Bumi reacted after the old man's question, and looked at Jiang Xingchen in confusion, waiting for the answer!

Jiang Xingchen smiled and nodded, "There should be sulfur near the volcano, I need this thing!"

"Sulphur, what is that?" The old man was curious.

"A yellow ore can be used to do many things..." After looking at the old man, Jiang Xingchen continued: "It can also be used as a medicine to treat diseases! Sulfur cream is very effective in treating eczema and other things."

"What?" The old man's mouth opened wide instantly. Ores can also be used as medicine. You're right.

"What kind of expression do you have? Is it strange to be a drug? You are still a great doctor. You don't even know this..." Jiang Xingchen looked at the old man with some contempt.

"No..." The old man felt a little confused and asked, "What... how can I eat that ore?"

"Why can't you eat it... Salt is a mineral. The salt of the Great Qin Kingdom is dug from salt mines! Alkali is also a mineral, so you don't need to steam buns... Also, our Xingchen Ling uses not only brine for making tofu. The same is true for gypsum! These minerals can be eaten! Moreover, raw gypsum has the effect of removing fire and eliminating accumulation. Don't you know?"

Although Jiang Xingchen made her intestinal thread and syringe, he really didn't go into the medical field too much. He really didn't know that the medicines in this world are basically herbs. They didn't use minerals.

"You are not wrong with raw gypsum?" The old man excitedly grabbed Jiang Xingchen. As a great doctor, he was quite persistent in medicine. He had been studying for a abdominal pain for decades.

If what Jiang Xingchen said is true, it would be amazing. This is equivalent to breaking the cognition of traditional medicine for countless years.

Jiang Xingchen was frightened by the old man's expression. The old guy was so excited. He said suddenly: "That...haha. I'm talking nonsense, I can't do it accurately. I don't know whether it's okay..."

Jiang Xingchen didn't dare to say he was dead. Although he knew the medicinal value of the gypsum in his previous life, who knew that in this life, there was a difference between the two worlds. He had not found the most common thing like saltpeter, so far, but he knew if there was any essential difference between the human body.

"Don't worry about whether it's okay or not, just try it!" The old man laughed, and didn't bother asking about the volcano anymore. He patted Jiang Xingchen hard and said loudly: "If it really happens, the entire medical community will take a big step forward!"

After the words came, the old man turned around and ran away. He had to write a letter to Huangshi and Qingyun immediately and ask these two guys to do an experiment. He could not find raw plaster here, so he had to ask Xingchen to send it to Huangshi.

He believed that Huang Shi and Qingyun would definitely be shocked to fall off after seeing this letter!

When the old man ran out, Jiang Xingchen rubbed the place where he was photographed, his mouth twitched wildly, and cursed in his heart: "It's so cheap... I'm so full that I'm talking about this, just tell them that sulfur is useful, and it's also a medicinal value! Now, the old man will definitely go and tell Huang Shi and Qingyun that if he eats people with raw plaster, it would be a real sin!

Jiang Xingchen was stunned here, but Qin Manwu and Qun Bumi were relieved. Jiang Xingchen wanted this volcano not to refuse, but to be useful... Then they were surprised that the volcano was useful.

After a moment of silence, Qin Manwu's thoughts returned to the desert. The scale and status of the world's business can reach its current scale and status is entirely because of the original result of the opening of the desert line. It is said that it is the pillar of the world's business. Since the accident in the desert, she has almost thought about how to solve it every day.

Originally, she was at a loss, but Jiang Xingchen solved the drought, which made her see hope all of a sudden. Isn’t the situation in the desert also caused by water drought?

"Jiang Xingchen, in the desert, why don't you think of a solution too!" Qin Manwu said, waiting for the reply with hope.

Jiang Xingchen frowned and shook his head and said, "On the desert... I can't solve it for the time being!"

"How is that possible? Haven't you solved the drought here?" Qin Manwu asked immediately.

"What is this called a solution? It just ensures that the grain production areas can finally be harvested! The grains we use now are the best quality varieties improved by Yuanshi. They have strong vitality and drought resistance, as long as there is a small amount of water. Otherwise, even if there are nearly 100,000 water-pressing wells that pump out 28 days and nights a day (monthly) and cannot supply such a large planting area..."

After sighing softly, Jiang Xingchen continued, "This is still here. When it comes to the desert water-deficient areas, the difference is even greater... Moreover, the groundwater here is all shallow water layers, which are easy to drill holes. It is different there. If you want to get water, you have to dig a deep well and get the water between the two water barriers!"

Jiang Xingchen didn't want the business problems in Shahai to go, but now he is really powerless, let alone digging deep wells. He can't even detect and position them now.

To solve the problem of water-relief in the desert, the formation must first develop to the next stage, and the power device must be used. Digging deep wells cannot be done manually.

After listening to Jiang Xingchen's explanation, Qin Manwu realized that it was really impossible to do, and she could only shake her head regretfully.

"You don't have to worry. The losses in the sand sea are only temporary. We will go there after they stabilize." Jiang Xingchen persuaded.

He said this, but he didn't think so in his heart. If two major forces were fighting each other, it would be normal for ten or eight years to fight. The desert had to give up.

After making this heartbreaking decision, Jiang Xingchen had to comfort Qin Manwu: "We have not opened tea to the public in recent years. Let's sell it on the spot during this period! The price may not be as high as the desert, but we have saved the shipping fee!"

When Jiang Xingchen said this, Qin Manwu burst into laughter. Xingchen received expensive things, but the shipping fee was really not too much, and there were not many carriages.

However, after Jiang Xingchen's persuasion, Qin Manwu felt much better! In fact, some people bought tea and other things in major kingdoms and the Qiankun Empire, but she was just too concerned about the desert before! What's more important is that he was worried that Jiang Xingchen would hand over the tea to the Wang family... Now that she knew Jiang Xingchen's thoughts, she of course felt relieved.

Afterwards, the two discussed when they would send someone to the volcano to take a look. Qin Manwu and Jun Bumi said goodbye and left.

Not long after, the old man came back and kept asking what minerals were there for medicinal use.

Can Jiang Xingchen know about raw gypsum or watch it in a health program in his previous life. The sulfur paste was because a buddy went in and said when she came out after drinking. As for other minerals that can be used medicinal, how could he know?

But the old man didn't believe it and kept asking. In the end, Jiang Xingchen couldn't stand it anymore and called out Pink, saying that the old man's cultivation level had increased greatly and he wanted to practice with it.

When the pink heard this, he chirped happily, and it had not been active for a long time.

The old man was so angry that he scolded the streets. This little soul was so devastated that he wouldn't play like this! I was so stupid that I said this to Pink. Is that good to be trained?

He firmly disagreed with the event with the pink ones, and the old man refused loudly, turned his head and ran out.

Pink finally had the opportunity to move, so of course he was unwilling to give up, so he followed him out...and then, nothing happened...

The next morning, Jiang Xingchen set out and set off. The old man was surprisingly silent, sitting in a carriage without showing his face, and not even saying a word.

At first, Jiang Xingchen didn't care, but Jiang Xingchen felt something was wrong after a while. This old guy couldn't stay idle for a while, and now it's too quiet.

The more I thought about it, the more curious he became, Jiang Xingchen ran to the old man's carriage. As soon as he entered the car door, he burst into laughter. The old man's eyes were beaten like Zoro with a mask.

If it’s just like Zorro, Jiang Xingchen is smiling pink. How did it beat the old man like this? Is it unscientific to clench his wings into fists?

But next, Jiang Xingchen couldn't laugh! (To be continued, please search for Astronomy, novels are better, updated and faster!
