The Strongest Lu Bu's Sweeping Thousands of Armies

Chapter 360 Sulfuric Acid Can Be Made From Green Alum

The second explanation given by Lu Bu completely convinced Zhou Yu.

There are indeed rare goods that can be lived in.

If there is too little of something, its value will skyrocket, and once there are more of such things on the market, its value will also drop.

Lu Bu promised Yuan Shao that he would supply coal to Hebei, and the price would be [-]% of the market price.

Seventy percent of what they negotiated was based on the price of coal on the market.

The less coal produced, the more money Hebei spent and the less coal it took away from Xuzhou.

Zhou Yu agrees with Lu Bu's statement.

He asked Lu Bu, "What does Marquis Chu mean to wait until the Yuan family turns against each other in the future before increasing coal production?"

"Actually, there are a lot of coal in the world." Lu Bu said, "I haven't solved the problem of lighting under the mine yet, and heroes from all over the world are watching, and I am not allowed to mine other coal mines. When our power is more stable, I will We have found a way to no longer use open flames for lighting under the mine, which will of course allow the artisans to mine more coal. After all, we will conquer the world in the future, and we will need a lot of coal to forge weapons."

"The Marquis of Chu always said that there is no need to use open flames in the mine." Zhou Yu asked, "Is there any way to do it?"

"At first I thought about extracting sulfide during coal desulfurization." Lu Bu said: "But the process of doing that is too complicated, and requires a lot of equipment and raw materials. After thinking about many methods, I finally decided to use green vitriol to make Sulfuric acid is cheaper."

"Green vitriol?" Zhou Yu was confused when he heard that, "Green vitriol is generally used as medicine, and the price is extremely low. I don't know what Chuhou wants to make with that thing... What is the use of sulfuric acid?"

Zhou Yu knew green vitriol, but he had never heard of sulfuric acid, so when he said this term, he stuttered somewhat.

"Sulfuric acid and copper react to generate electricity." Lu Bu said, "Although I don't have the ability to build a power grid and change the energy sources the world is accustomed to using, I can make some light sources that can support craftsmen to use under mines. .”

In fact, when he said this, Lu Bu was also uncertain.

He couldn't afford to build a power grid. Even if he made a mine lamp that can emit light by reacting sulfuric acid and copper to generate electricity, how to recharge it when the electricity in the lamp is used up is a question worth considering.

The use of open flames as a light source in underground mines has always been a problem that has plagued Lu Bu.

He thought of many methods, but none of them could be implemented.

The light source without open flames is not a problem after 2000, but in this era, it has become an insurmountable problem...

Lu Bu felt that he urgently needed some talents.

These talents are not strategists who know how to strategize, nor are they military generals who travel across the battlefield as if they are in no one's land, but some talents who are extremely interested in scientific exploration...

But the world is so big, where to look for such talents in this era?

Thinking of this, Lu Bu frowned.

Seeing something wrong from his face, Zhou Yu asked, "What's wrong with Marquis Chu?"

"It's nothing." Lu Bu replied first, and then asked Zhou Yu, "Do you know where there are people who know how to count and mechanism?"

"Arithmetic and mechanical techniques." Zhou Yu thought for a while and said, "I know the prefect Liu Hong of Sanyo who is proficient in arithmetic, and Fufeng Majun is the one who understands mechanical techniques."

"Where can I find these two people?" Lu Bu asked.

Zhou Yu replied: "Liu Hong is easy to find, but he is in Shanyang, which is the boundary of Yuan Tan, and it is not easy to bring him back."

"As long as I get what I want, it's not easy." Lu Bu smiled slightly: "After I go back, I will arrange for someone to bring Liu Hong. Where is that Ma Jun?"

"Ma Jun is in the Ma family in Xiliang." Zhou Yu replied, "Although he is good at tricks, he is not good at speech, so he is not very popular in the Ma family..."

"It's just because he's not good at words?" Lu Bu asked.

"It should be." Zhou Yu replied: "Because he is not well received, mechanism skills have also been buried, which is a pity..."

"The Ma family lived in Xiliang for a long time, and most of them are the same as the local Qiang people. They don't agree with some delicate things, and they always feel that they can do against the sky with just human strength." Lu Bu shook his head and said. : "It's a pity that someone like Ma Jun stays in Xiliang, we have to find a way to get him too."

"It shouldn't be difficult to convince Ma Jun." Zhou Yu replied, "The Marquis of Chu sent an eloquent person to Xiliang, and promised him some benefits."

"As long as he is willing to come, the beauty and the money are up to him." Lu Bu replied straightforwardly.

"A character like Ma Jun should not be very interested in beauties and money." Zhou Yu said: "As long as Chu Hou allows him to do something, he will definitely come to do it."

"What Gongjin said is true." Lu Bu said, "As long as Ma Jun is willing to come, I will specially build a place for him to study mechanism techniques."

"Actually, Chu Hou has one thing that is enough to attract Ma Jun." Zhou Yu said: "The glider that Chu Hou personally supervised and built, Ma Jun is very familiar with mechanism techniques, and he probably didn't expect that there would be something that could bring people on it. In the air, soar like a bird."

"Gong Jin thinks clearly." Zhou Yu mentioned the glider, and Lu Bu immediately said: "Gong Jin recommends someone to come over and ask him to persuade Ma Jun to vote for me. As long as Ma Jun is willing to come, build another courtyard for him to develop Mechanism is inevitable, and I will also tell him how to make glider and hot air balloon."

"Actually, Marquis Chu has someone available." Zhou Yu said, "Marquis Chu defeated Yuan Shu and obtained Yan Xiang from Huainan. Yan Xiang can speak eloquently, and if he persuades Ma Jun, he will definitely be captured."

"Yan Xiang is already old." Zhou Yu recommended Yan Xiang, and Lu Bu said with some embarrassment: "I don't know how far it is from Xuzhou to Fufeng. I always feel that I can't bear to ask Yan Xiang to go there to persuade Ma Jun..."

"Although the journey is long, it's enough for Marquis Chu to settle him down." Zhou Yu said, "Marquis Chu can arrange a carriage for him, and more than a dozen guards and two maids will follow and take care of him. There are guards to protect him , and there is a maid to take care of the daily life, even though he is a bit older, I don’t think Yan Xiang can’t go to Fufeng. What’s more, when he arrives in Fufeng, he doesn’t need to do anything, as long as he sees Ma Jun, he can persuade him to come to Xuzhou.”

"We openly recruited Ma Jun from Fufeng. What if the Ma family refuses to agree?" Lu Bu asked Zhou Yu, "If we get into a fight with them, wouldn't it be another opponent?"

"As I said just now, Ma Jun is not seen at all in Fufeng, and his mechanism skills are often the source of ridicule." Zhou Yu said: "The Marquis of Chu sent people to Fufeng to recruit Ma Jun, and the people there only He would think that Marquis Chu is crazy to want such a useless person. Since this person is useless, how can the Xiliang Ma family obstruct it?"

"That's true." Lu Bu nodded: "Back to Pengcheng, Gongjin helped me invite Yan Xiang to the study, and said that I had something important to discuss with him."

He then asked Zhou Yu: "Shanyang Liu Hong, does Gong Jin have anyone to recommend?"

"If there is nothing to do, I can recommend many people." Zhou Yu replied: "Now that the Duke of Chu's crusade against Cao Cao is imminent, it is time to employ people around him. The only ones who can go to Shanyang to bring Liu Hong back are those who are stationed on Mount Tai. Two generals, Zang Ba and Sun Guan."

"The two generals guard Mount Tai together with Pang Shiyuan." Lu Bu shook his head and said, "If they go to Shanyang, wouldn't it be the same as declaring war on Yuan Tan?"

"If the Marquis of Chu is worried about this, he should order Pang Shiyuan to find a way to get Liu Hong to Pengcheng." Zhou Yu said, "Pang Shiyuan is very wise, so there should be no difficulty in getting Liu Hong."

Zhou Yu's proposal is reasonable, and it is indeed the best solution at the moment.

Lu Bu nodded, and said to Sun Ce who was following on the other side: "Bo Fu, send someone to Mount Tai and tell Pang Shiyuan that no matter what he thinks, he must get the prefect of Shanyang, Liu Hong, to Pengcheng. Remember to tell him not to hurt Liu Hong's hair no matter what. I want Liu Hong, if it is of great use."

Sun Ce didn't delay, and turned to a guard and asked, "Did you hear what the Marquis of Chu said?"

The guard led his horse and rode away.

Lu Bu took Zhou Yu, Sun Ce and others back to Pengcheng, Zhou Yu went to invite Yan Xiang, and he went straight back to the government to go to the study.

Since the change of person in the skin, the study that Lu Bu seldom visited in the past has now become the place where he stays the longest.

The collection of books in the study room are all classics from the past, which cannot tell what will happen to Lu Bu in the future.

He didn't care about these, he would sit for a long time every time he got into the study.

Although it is impossible to find out what will happen in the future from the classics in the study, Lu Bu can learn a lot about this era from them.

The folk customs and military formations of various places, and even the construction of water conservancy, astronomical astrology, these can be found in the classics.

It's just that the classics of this era are not equipped with illustrations like the books of later generations.

When encountering some awkward and difficult questions, Lu Bu could only figure out a little bit, thinking about how to understand the classics.

When he was in the coal mine earlier, he thought of making sulfuric acid from green vitriol.

With sulfuric acid, copper flakes are of course easy to get.

The next problem to be solved is how to make the most primitive battery through the action of sulfuric acid and copper sheets, and what method should be used to ensure that the battery has enough power to support miners in underground lighting.

In the era he lived in, electricity has long been the energy source most used by human beings.

But in this era, people only know that electricity is the bright lights that split through the time and space of the rainstorm, but they don't understand that once this kind of light is controlled by people, it can bring endless benefits to people.

Surrounded by people who don't understand these things at all, it is impossible for Lu Bu to find someone who can discuss power generation methods.

Even if people like Liu Hong and Ma Jun were found by him, they would not know what is called electricity, what is called magnetic field, and how to use these things to promote the rapid development of science and technology...

Searching through the volumes of classics, Lu Bu still couldn't find what he needed, when Sun Ce's voice came from outside the door: "Report to Marquis Chu, Lord Yan is here."

The Lord Yan that Sun Ce mentioned is of course Yan Xiang.

Lu Bu looked away from the scroll in front of him, and said to Sun Ce: "Please come in and talk, Mr. Yan."

Sun Ce, who was guarding the door, made way for Yan Xiang, and said to him, "Mr. Chu invites Lord Yan to enter the study."

Yan Xiang cupped his hands towards Sun Ce: "Thank you, General Sun."

After entering the study, Yan Xiang bowed to Lu Bu with a big gift: "I have met the Marquis of Chu."

"You don't need to be polite, Mr. Yan, please sit down." Lu Bu stood up and asked Yan Xiang to sit down.

He has long served under Lu Bu's command. Speaking of which, he is also the master of Yan Xiang. When Yan Xiang came, he would stand up to greet him, which made Yan Xiang a little confused.

After a few words of humility with Lu Bu, Yan Xiang sat down and asked him, "Dare to ask Marquis Chu, do you have any orders for calling me here?"

"Let's not talk about things first." Lu Bu waved his hands with a smile, looked at Yan Xiang and asked: "How is Yan Gong's health recently? Are you still walking as fast as before?"

"Back to the Marquis of Chu." Yan Xiang said, "Although I am old, I am not deaf and blind. It shouldn't be a problem to do some things for the Marquis of Chu."

"I know that Mr. Yan has always been in good health, but there is a tricky matter right now, and I really can't get anyone out, and this matter needs someone to go a long way, and it can only be done in Fufeng, Xiliang... " Lu Bu said with a troubled face: "Yan Gong is not young, and Xiliang is a long way away. Although I intend to ask Yan Gong to go there, I feel that I can't bear it..."

"What should I do?" Yan Xiang said: "The Marquis of Chu is about to attack Cao Cao, and it is time to employ people. Most of the people under the Marquis of Chu are capable, and I am the only one who is useless. Going to Fufeng is also I can do something for the Marquis of Chu, and I am willing to work for the Marquis of Chu."

"I'm not worried that Mr. Yan won't be able to do things." Lu Bu said to Yan Xiang with a perplexed face, "I'm just worried that Mr. Yan is old, and whether he can bear such a long journey..."

"Chu Hou underestimated me." Lu Bu bluntly said that he was old and worried about whether he could walk such a long distance, Yan Xiang replied: "Although I am a little older, I am not so old that I can only lie there and move around." No. Since Chuhou doesn't believe me, why did he call me here?"

"Don't get angry, Mr. Yan." Yan Xiang showed some anger on his face, and Lu Bu laughed as if he had made a mistake, and said, "Since Mr. Yan is willing to go, I will arrange more guards and a few maids to accompany me, so that I can Take it easy."

"Could it be that Marquis Chu still thinks I'm too old?" Yan Xiang said, "If that's the case, I should resign and return to my hometown."

"I just want to arrange a few more people to escort Yan Gong, for peace of mind." Lu Bu said: "Yan Gong must not take it to heart."

Lu Bu was with you, Yan Xiang looked a little better: "Please tell Marquis Chu clearly what you want me to do in Xiliang, and ask me to leave early tomorrow morning."
