Ma Jun, director of the Academy of Science and Technology, and Chen Gui, deputy director of the Academy of Science and Technology, successively developed gunpowder, assault guns, and steam engines, and made great contributions to Lu Bu. The place where they lived, it was extremely luxurious.

However, no matter how luxurious it is, it is only limited to the science and technology institute.

All members of the Academy of Science and Technology, including Ma Jun and Chen Gui, are not allowed to come and go at will.

Lu Bu hadn't been to the Academy of Science and Technology for more than a year, and he was a little surprised to see the changes in the Institute.

The change of the Institute of Science and Technology also shows that the officials of the DPRK and the Central Committee attach great importance to it, and all departments have vigorously supported it, especially the Ministry of Household Affairs and the Ministry of Industry.

"The lord is here..."

Lu Bu had just entered the Science and Technology Institute, and someone who knew Lu Bu went in to report the news.

Ma Junhe greeted him: "The lord (father-in-law)." ”

"Listen to Mr. Gongtai, you invented glue?" Lu Bu walked to an open living room and found a place to sit down.

"Yes."

Ma Jundao: "We collect the gum and propolis, go through some treatment, and then seal it. Reheat when you want to use it. After our initial research, he was very useful. It's just that... This stuff is a hassle to collect. If you can plant trees or keep bees, you will definitely collect more. ”

Hey?

Lu Bu suddenly found that Ma Jun didn't stutter anymore!

"You've been cured of your stuttering problem?" Lu Bu asked.

Ma Jun scratched his head and said with a smile: "Thanks to the lord." It took more than a year of practice before he could barely get rid of that bad habit. ”

"Okay, if you get rid of your stuttering, you'll be able to report better. Let's take me to see the gum and propolis first. Lu Budao.

"My lord, please."

Under the leadership of Ma Jun and Chen Gui, they came to a large square. There are a lot of jars in the square, and the jars are full of gum and propolis.

Ma Jun made an introduction one by one...

Gum and propolis, although called gum, are in a liquid state. When it is solid, it is brittle. It's not the kind of rubber that Lu Bu wants to make tires at all.

Lu Bu regretted it in his heart. Why didn't you go to school in the first place?

Lu Bu praised Ma Jun a few words, changed his words, and asked, "Ma Jun, stereotyped." You guys should think... A hard rubber is made, and when it is solid, it can withstand tremendous pressure.... ”

Lu Bu told them about the structure and appearance of tires in later generations, as well as his own ideas for tires.

However, as he spoke, Lu Bu couldn't go on anymore. Because he doesn't know anything. He couldn't even figure out what he said, whether it was true or not.

The material of gum and propolis is obviously not made of tires.

Lu Bu thought for a moment and said, "You can try to add some other things to it." Enhance its viscosity and softness after solidification. Or look for other glues. Don't be in a hurry, study slowly. ”

"Yes."

They never dared to slack off on what Lu Bu ordered.

But for what is hard rubber? Able to withstand a lot of pressure? Ma Junhe really didn't know anything about it, let alone imagined. They could only try as much as they could according to Lu Bu's request.

After walking around the Academy of Science and Technology and learning about the development of the Academy of Science and Technology for more than a year, Lu Bu returned to the Assassin's Mansion.

It just so happened that Fan Lihua and Mu Guiying also returned from the front line.

Assassin's House.

Vestibule.

"Husband, you haven't been back for more than a year."

"yes."

Lu Bra took their hands, sat down and said: "I went to Sichuan and Shu to fight for more than a year, and I didn't dare to come back until I drove Liu Bei away and occupied Sichuan and Shu." During Yuan Shao's Northern Expedition, thanks to you. ”

"When the husband says this, he will see the outside."

"Yes, Yuan Shao's Northern Expedition, can we not do our best?" Mu Guiying said.

Fan Lihua took Lu Bu's hand and said with a smile: "Okay now, Yuan Shao has been defeated by us, and Qingzhou has also been occupied by us." Xu and Qing are connected, and then there is Ganning's navy to clamp down on the Yellow River, and the strength of our Qingxu and Xu states has doubled. Whether it was Yuan Xi, Yuan Shang or Cao Cao, they didn't dare to make it easily. We can also stay in Shouchun from time to time. ”

Lu Bu said: "If you like to stay in Shouchun, stay in Shouchun." There is a newly appointed governor of the navy in Qingxu and Xuzhou, Gan Ning, and nothing major will happen. ”

"Governor of the Navy? Isn't it the governor of the navy? Mu Guiying asked.

"I used to be the Governor of the Navy, and now I am the Governor of the Navy. It is in charge of the waters of the Yellow River from Qingzhou to Yanzhou. Lu Bu explained, and said: "After I returned to Shouchun, I didn't have to rush to hold a celebration party for the meritorious soldiers, and I didn't go to the military aircraft department, so I don't know how Qingxu and Xu are doing now." Since you are here, tell me about it. ”

"Okay..."

Fan Lihua poured three bottles of tea, sat down again and said, "My Xuzhou army suffered half of the casualties in the battle against Yuan Shao. Later, according to the instructions of the Military Aircraft Department, the army was expanded to 150,000. Although their combat effectiveness is weaker than before, the soldiers are highly motivated and actively trained, and as long as they are given more time, I believe that their combat effectiveness will be stronger. ”

Mu Guiying also said: "Qingzhou is the same. The military aircraft department gave Qingzhou an army structure of 200,000. Originally, it was a little difficult to recruit soldiers and horses, because the young and middle-aged people in Qingzhou were all recruited by Yuan Tan. However, we captured a large number of Yuan Tan's soldiers and horses, as well as some family private soldiers, and exterminated the thieves near Mount Tai. In total, there are more than 300,000 young people. I picked two hundred thousand out of them. After a few months of training, it's not bad. The soldiers were also high-spirited and looked forward to crossing the Yellow River and unifying Hebei as soon as possible. ”

"It's good to have fighting spirit. I believe that when the war starts, whether it is the Xuzhou Army or the Qingzhou Army, they will be comparable to Yuan Xi and Yuan Shang's Hebei Army! Lu Budao.

"That's..."

Fan Lihua and Mu Guiying are also not modest at all.

I spoke for a while.

Pan Jinlian came back from outside and said a strange thing: "Husband, two sisters, let me tell you, I went to check the accounts just now and found that the price of medicinal materials is ten times that of last year!" The price of grain is three times higher than last year! ”

"So expensive?"

Fan Lihua and Mu Guiying were taken aback.

Lu Bu frowned and said, "The increase in the price of medicinal materials and grain, could it be the result of a large number of purchases by your Chamber of Commerce, resulting in a shortage in the market?" ”

"Of course it's possible."

Pan Jinlian said: "But... I am not talking about the strange thing, but the price of medicinal herbs and food has risen. But now there are merchants who are selling in large quantities, and I have bought a lot of them, especially saltpeter.... ”

"What?!"

Lu Bu, Fan Lihua and Mu Guiying stood up together. They all knew that saltpeter was the main material for making gunpowder, and it was out of stock a few months ago, so the Academy of Science and Technology could no longer make gunpowder.

Unexpectedly, Pan Jinlian actually said that someone was selling saltpeter.

"What's wrong with you?"

"Someone selling saltpeter?" Lu Bu asked Pan Jinlian in surprise.

"yes."

Pan Jinlian said: "In just a few days, we have collected more than 200 catties. Of course, the price has also increased several times. It is estimated that our chamber of commerce is eager to collect all kinds of medicinal materials, so it wants to make more benefits. ”
