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

There are indeed strange things in the world.

If something is too little, its value will soar to a very high level, and once there are more such things on the market, its value will also fall.

Lü Bu promised Yuan Shao to supply coal to Hebei, and the price was seventy percent of the market price.

Seventy percent of what they negotiated was measured by the price of coal in the market.

The lower the coal production, the more money Hebei spends and the less coal it takes from Xuzhou.

Zhou Yu agrees with this statement given by Lu Bu.

He asked Lu Bu, "Does the Marquis of Chu mean to wait until the future to turn against the Yuan family and then increase the output of coal?" ”

"In fact, there is really a lot of coal in the world." "I haven't solved the problem of lighting under the mine, and I'm not allowed to mine other coal mines," Lu said. When our power is more solid, I have found a way to stop using open flames under the mines, and of course let the artisans mine more coal. After all, we will conquer the world in the future, and we will also need a lot of coal to forge weapons. ”

"Chu Hou always said that there is no need for open flames under the mine." Zhou Yu asked, "I don't know if there is any way to do it?" ”

"At first I thought about extracting sulfides when the coal was desulphurized." Lu Bu said: "But the process of doing that is too complicated, and it requires a lot of equipment and raw materials. I thought about a lot of methods, but in the end I still felt that it was more cost-effective to make sulfuric acid from green alum. ”

"Alum?" Zhou Yu was confused when he heard it: "Green alum is generally used for medicine, and the price is extremely low, I don't know what Chu Hou wants to make of that thing...... Sulphuric acid...... What's the use? ”

Zhou Yu knew about green alum, but he had never heard of sulfuric acid, so when he said this term, he was a little stumbling.

"Sulfuric acid reacts with copper to produce electricity." "Although I don't have the ability to build a power grid and change the energy that people are used to using in the world, I can make some light sources that can support the craftsmen in the mines," Lu said. ”

In fact, when he said this, Lu Bu was also bottomless in his heart.

He couldn't afford to build a power grid, and even if he built a mine lamp that could produce electricity by reacting sulfuric acid and copper, it was worth considering how to charge it when the electricity in the lamp ran out.

The light source that does not use open flames underground has always been a problem that plagues Lu Bu.

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

The light source without an open flame is not a problem at all after 2,000 years, 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 on the battlefield as if they were in a no-man's land, but some talents who have some extremely strong interest in scientific exploration......

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

Thinking of this, Lu Bu frowned.

Seeing that something was wrong on his face, Zhou Yu asked, "What's wrong with Chu Hou?" ”

"Not really." Lu Bu first replied, and then asked Zhou Yu: "Do you know where there are talents who know how to count and trick up?" ”

"Arithmetic and tricks." Zhou Yu thought for a while and said: "For those who are proficient in arithmetic, I know that there is Shanyang Taishou Liu Hong, and those who know how to do tricks have Fufeng Ma Jun." ”

"Where can these two men be found?" Lu Bu asked.

Zhou Yu replied: "Liu Hong is easy to find, but he is in Shanyang, which is Yuan Tan's territory, and it is not easy to bring him back." ”

"As long as I want it, I haven't heard that 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 at Xiliang Ma's house." Zhou Yu replied: "Although he is good at mechanical skills, he is not good at words, and he is not very popular in the Ma family......

"Not being treated well because he is not good at words?" Lu Bu asked.

"It should be." Zhou Yu replied: "Since he is not welcomed, the mechanism technique has also been buried, which is a pity........."

"The Ma family has been in Xiliang for a long time, and most of them are the same as the local Qiang people, they don't agree with some exquisite things, and they always feel that they can do it against the sky just by relying on the power of people." Lu Bu shook his head and said, "It's a pity that a character like Ma Jun stays in Xiliang, I have to find a way to get him too." ”

"It shouldn't be difficult to convince Ma Jun." Zhou Yu replied: "Chu Hou sent a man who can speak well to Xiliang and promise him some benefits." ”

"As long as he is willing to come, the beauty and money are at his disposal." Lu Bu replied very happily.

"Characters like Ma Jun shouldn't be very interested in beauty and money." Zhou Yu said: "As long as Chu Hou allows him to do something, he will definitely come to serve." ”

"That's what Gong Jin said." Lu Bu said: "As long as Ma Jun is willing to come, I will specially build a place for him to study the mechanism technique for him." ”

"Actually, there is one thing here in Chuhou that is enough to attract Ma Jun." Zhou Yu said: "The glider built by Chu Hou himself, Ma Jun knows a lot about the tricks, and he probably didn't expect that there would be something that could take people into the air and soar like birds." ”

"It's still Gongjin who thinks clearly." Zhou Yu mentioned the glider, and Lu Bu immediately said: "Gong Jin recommended someone to come over and let him persuade Ma Jun to come and vote for me." As long as Ma Jun is willing to come, it is inevitable to build a courtyard for him to develop the mechanism technique, and I will also tell him how to make gliders and hot air balloons. ”

"Actually, Chu Hou has someone available." Zhou Yu said: "At the beginning, the Marquis of Chu broke Yuan Shu and got Yan Xiang from Huainan. Yan Xiang is a person who can speak well, and if he tries to persuade Ma Jun, he will definitely be caught. ”

"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, let Yan Xiang go there to persuade Ma Jun, I always feel unbearable......

"Although the road is long, Chu Hou only needs to settle him down." Zhou Yu said: "Chu Hou can arrange a carriage for him, and more than ten guards and two maids will follow him. There are guards to protect him, and there are maids to take care of his daily life, although he is older, I feel that Yan Xiang is not unable to go to Fufeng. What's more, when he arrives in Fufeng, he doesn't want him to do anything, as long as he sees Ma Jun and persuades him to come to Xuzhou. ”

"We openly recruited Ma Jun from Fufeng, if the Ma family doesn't agree, what should we do?" Lu Bu asked Zhou Yu: "If you fight with them, won't you have another opponent?" ”

"I already said just now that Ma Jun is not treated at all when he is helping the wind, and his skills often become the source of ridicule." Zhou Yu said: "Chu Hou sent someone to Fufeng to recruit Ma Jun, and the people there would only think that Chu Hou was crazy and would want such a useless person." Since this person is useless, how can the Xiliang Ma family obstruct it? ”

"That's right." Lu Bu nodded: "Back in Pengcheng, Gong Jin 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, is there anyone available for Gongjin to recommend?" ”

"When I'm not doing anything, I can recommend a lot of people." Zhou Yu replied: "Now that the Marquis of Chu is crusading against Cao Cao, it is time to employ people around him. The only people who could go to Shanyang to bring Liu Hong back were the two generals Zang Ba and Sun Guan, who were stationed in Mount Tai. ”

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

"If Chu Hou is worried about this, then give an order to Pang Shiyuan and ask him to find a way to get Liu Hong to Pengcheng." Zhou Yu said: "Pang Shiyuan is wise, it shouldn't be difficult to get a Liu Hong." ”

Zhou Yu's proposal is reasonable, and it is indeed the best way to deal with it at the moment.

Lu Bu nodded, and said to Sun Ce, who was following on the other side: "Bo Fu, you send someone to Mount Tai and tell Pang Shiyuan that no matter what method he thinks, he must get Liu Hong, the Taishou of Shanyang, to Pengcheng for me." 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, turned back to a guard and asked, "Did you hear what Chu Hou said?" ”

The guards were ordered to ride their horses away.

Lu Bu returned to Pengcheng with Zhou Yu, Sun Ce and others, Zhou Yu went to invite Yan Xiang, and he went directly back to the official mansion to the study.

Since the change of person in the skin, the study room that Lu Bu used to rarely go to now has become the place where he stays the longest.

The books in the study are all classics from the past, and they can't tell Lu Bu what will happen in the future.

He didn't care about any of that, and sat for a long time every time he went into the study.

Although he couldn't find out what would happen in the future from the classics in the study, Lu Bu could learn a lot about this era.

The folk customs and the art of war in various places, and even the construction of water conservancy, astronomy and astronomy, can be found in the classics.

It's just that the classics of this era are not as illustrated as the books of later generations.

When encountering some jerky and difficult questions, Lu Bu could only figure it out little by little, pondering how to read the classics thoroughly.

When he was in the coal mine, he came up with the idea of making sulfuric acid from alum.

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

The next problem to be solved is how to make the most primitive battery through the action of sulfuric acid and copper sheets, and how to ensure that this battery has enough power to support the miners to light the mine.

He lived in a time when electricity had long since become the most used energy source for mankind.

But in the current era, people only know that electricity is a bright light that cleaves in the time and space of a rainstorm, and they do not understand that this kind of light can bring endless benefits to people once it is controlled.

He was surrounded by people who didn't understand these things at all, and it was impossible for Lu Bu to find someone who could discuss power generation methods.

Even if characters like Liu Hong and Ma Jun were really found by him, it would be impossible for them to know what electricity and magnetic fields were, and how to use these things to promote the rapid development of science and technology......

Rummaging through the volumes of classics, Lu Bu hadn't been able to find what he needed, and Sun Ce's voice came from outside the door: "Qiqi Chuhou, Yan Gong is here." ”

The Yan Gong that Sun Ce said is, of course, Yan Xiang.

Lu Bu's gaze moved away from the scroll in front of him, and he ordered Sun Ce: "Quickly invite Yan Gong to come in and speak." ”

Sun Ce, who was guarding the door, made way for Yan Xiang and said to him, "The Marquis of Chu invites Yan Gong into the study for a while. ”

Yan Xiang arched his hand towards Sun Ce: "Thank you, General Sun." ”

Entering the study, Yan Xiang bowed to Lu Bu and bowed: "I've seen Chu Hou." ”

"Yan Gong doesn't need to be polite, please sit down." Lu Bu got up and beckoned Yan Xiang to sit down.

He has long been under the command of Lu Bu, and he is also the lord of Yan Xiang, when Yan Xiang came, he would actually get up to greet him, which made Yan Xiang a little confused.

After a few humble words with Lu Bu, Yan Xiang sat down and asked him, "Dare to ask Chu Hou, is there anything to call me over?" ”

"Let's not talk about things yet." Lu Bu smiled and waved his hand, looked at Yan Xiang and asked, "How is Gong Yan's body and bones recently?" Can you still walk as fast as ever? ”

"Back to Chu Hou." Yan Xiang said: "Although I am old, I am not deaf and blind, and it should be no problem to do some things for Chu Hou." ”

"I know that Yan Gong has always been very healthy, but there are tricky things at the moment, I really can't pull out people, and this matter still needs someone to walk a long way, and it can only ......be done when they get to Xiliang Fufeng" Lu Bu said with embarrassment on his face: "Yan Gong is not young, Xiliang is far away, although I have the heart to invite Yan Gong to take a trip, but I feel that I can't bear to ......"

"What should I do?" Yan Xiang said: "The Marquis of Chu is about to crusade against Cao Cao, it is the time to employ people, and now most of the people under the command of the Marquis of Chu are capable, and only I am useless." If you go to Fufeng, you can also do something for Chu Hou, and I am willing to serve Chu Hou. ”

"It's not that I'm worried that Yan Gong won't be able to do anything." Lu Bu said to Yan Xiang with embarrassment on his face: "I'm just worried that Yan Gong is old, and if he can stand walking such a long way......"

"Chu Hou is underestimating me." Lu Bu bluntly said that he was old and worried about whether he could walk such a long way, Yan Xiang replied: "Although I am older, I am not there yet, so I can only lie there and not move. Since Chu Hou didn't believe me, why did he summon me here? ”

"Yan Gong, don't be angry." Yan Xiang's face showed some anger, and Lu Bu said with a smile as if he had made a mistake: "Since Yan Gong is willing to go, I will arrange some more guards and send a few maids to accompany me, so that I can feel more at ease." ”

"Could it be that Chuhou still thinks I'm too old?" Yan Xiang said: "If this is the case, I should resign and return to my hometown." ”

"I just want to arrange a few more people to escort Yan Gong to feel at ease." Lu Bu said: "Yan Gong must not go to his heart. ”

Lu Bu accompanied him, Yan Xiang's face looked a little better: "Please also ask Chu Hou to make it clear what you want me to do in Xiliang, and I have to ask me to leave early tomorrow morning." ”
