In order to advance the nuclear weapons program as soon as possible, Li Changfeng has to go to the scientific research institute every day in the past few days to guide the manufacture of cement plant equipment and the construction of a brick factory.

The brick factory was relatively simple, and because it did not use machinery, it was a labor-intensive industry, and it was quickly completed and put into use.

Even if he personally stared at it, the pass rate of the first batch of red bricks was less than fifty percent, and more than half of them could not be used.

Li Changfeng picked out the qualified products, summed up the experience on the spot, and the pass rate of the second batch of red bricks reached 70%.

At this time, Li Changfeng let go and devoted his energy to the construction of the cement plant.

Naturally, what he did couldn't hide from Emperor Qianwu.

Seeing that he had not gone to the Ministry of Railways or the air base for such a long time, Emperor Qianwu was a little angry, so he summoned him to the imperial study to reprimand.

"How long has it been since you went to the Ministry of Railways? I don't care about the construction of the Air Force, what are you busy with in a day? ”

Li Changfeng said helplessly: "The railway construction standards are there, there are special people to keep an eye on them, there is no need to go every day, right?" As for the Air Force, isn't there a Jianye? ”

Emperor Qianwu was angry: "Are you still reasonable to be a shopkeeper?" What clods of dirt have you been burning lately? Could that thing also make money? ”

"Father, don't look down on those clods, they will turn into red bricks when they are burned, and they will have a great effect."

"Humph! A pile of mud burned and still muddy, what can it do? ”

Emperor Qianwu was full of disdain and did not believe what Li Changfeng said.

Helplessly, Li Changfeng popularized the defects of today's Daqian building materials and the advantages of red bricks to Emperor Qianwu, and then focused on explaining him to cement.

In order to let Emperor Qianwu understand its advantages more intuitively, Li Changfeng said that the wall that had just been poured in concrete could not be exploded even by artillery.

Emperor Qianwu was taken aback when he heard this: "Can't even explode artillery?!" How is this possible? ”

Li Changfeng said helplessly: "Father, do you think your son will lie to you?" ”

Emperor Qianwu was only a little surprised, but he did not suspect that he was used to Li Changfeng creating miracles again and again.

He realized the importance of concrete, if it was used in the construction of city walls, it would become an unstoppable existence, whether it was used to defend against foreign or evil beasts, it had an irreplaceable and huge effect.

It's nothing short of transformative.

You know, with the current technology, if you want to build a strong city wall, you need a lot of glutinous rice paste, which is very costly, not to mention a waste of food.

The advent of cement will put an end to all this.

Red bricks will greatly shorten the construction time of the building.

"Good! Get the cement factory out as soon as possible, and when the reinforced concrete structure you mentioned comes out, I want to see for myself if it's really that hard! ”

Hearing is false, seeing is believing.

He had already decided that if it was really as hard as Li Changfeng said, then he would use this method to rebuild the walls of the palace first.

The next step is the city wall.

Emperor Qianwu has even begun to look forward to the scene of the entire Great Qian.

Li Changfeng said with a smile: "Don't worry about my father, don't look at the small profit of cement red bricks, but the amount of money used in the future will definitely be very large, but it is a big business to make money, and the sons must get it out as soon as possible." ”

Emperor Qianwu scolded with a smile: "You know silver in a day in your head, and you don't do anything serious, you also have to have a snack for the affairs of the railway and the air force." ”

……

Leaving the palace, Li Changfeng went to the railway construction site to have a look.

As for the air base, Li Changfeng didn't bother to go there.

The so-called construction of the air force now is nothing more than improving some of the shortcomings of hot air balloons exposed in the last war and making more hot air balloons.

Li Jianye is much more concerned about this matter than him.

However, he did remember another thing, and that was the production of steel bars.

He went to the steel mill and arranged the production of steel bars before returning home.

In the blink of an eye, a month has passed.

For such a long time, the red bricks produced by the brick factory have piled up.

Li Changfeng did not deliberately publicize this matter, nor did he order the news to be blocked, and it gradually spread among the people that this is a new type of building material, which has attracted the attention of many people.

But the movement is not very big.

After repeated experiments, the cement plant finally produced qualified cement.

Li Changfeng had people take cement, sand, gravel and steel bars, build a simple mold with wooden planks, and pour a wall about two meters high and half a meter thick in the artillery battalion.

Since it was summer, it was completely dry in nine days, and Li Changfeng reported the matter to Emperor Qianwu.

This day is early.

Chen Dingyuan, the head of the household, was reporting to Emperor Qianwu.

"Your Majesty, now His Royal Highness the Ninth Emperor of Daqian has become the first major taxpayer of my Daqian, with a total of more than 580,000 taels of taxes last month. It is no exaggeration to say that His Royal Highness the Nine Emperor Princes has become the pillar of my great finances! ”

Hearing this, the ministers looked different.

There is surprise.

There are concerns.

The most is jealousy.

I was surprised because Li Changfeng was able to pay so much tax in a month.

is worried because Li Changfeng has such financial resources that he can affect the situation of the DPRK.

Jealousy, that's easy to understand, can Li Changfeng not be blushing if he is so rich?

But Emperor Qianwu seemed to have not heard anything, a little distracted, and he didn't know what he was thinking.

"Your Majesty?"

Chen Dingyuan reminded.

Emperor Qianwu came back to his senses and asked, "Finished?" ”

"Yes, Your Majesty."

"Do you Aiqing still have something to do?"

Qunchen, you look at me, I look at you, and I didn't speak.

"Since there is nothing to do, you Aiqing will go to the artillery battalion with me."

The artillery battalion has always been extremely tightly protected, and although the southern and northern wars have made great achievements, none of the ministers of the DPRK and the Central Committee have seen them with their own eyes when they go out of the front-line soldiers.

Even the old general Ye Qingcang is the same.

Therefore, as soon as Emperor Qianwu said this, everyone's eyes lit up.

They thought it was to show them the power of artillery, and they had been curious about it for too long.

Emperor Qianwu got up and took two steps, then suddenly stopped.

"Gu Tiancheng and Gu Aiqing are here, right?"

Gu Tiancheng, the secretary of the Ministry of Works, hurriedly bowed: "Yes, Your Majesty." ”

"It's good to be here, let's go."

Emperor Qianwu nodded and took the lead out of the main hall.

Gu Tiancheng looked dazed.

Didn't you go to the artillery battalion, no matter how you look at it, it has something to do with the military department, and His Majesty suddenly asked him what was going on if he wasn't there?

Chen Dingyuan, the head of the household, stepped forward and asked, "Why did Your Majesty suddenly ask you?" ”

"I don't know."

"Your Majesty is a little absent-minded today, and I don't know what's going on."

Gu Tiancheng thought for a while and said, "It probably has something to do with the artillery battalion." ”

Emperor Qianwu didn't say anything, and the ministers didn't dare to ask, so they could only follow with doubts.

The emperor led the civil and military officials out of the city, and the movement was very large, which attracted the attention of everyone in the capital.

When they learned that they had gone to the artillery battalion, they became even more curious.
