Really a hit.

Brand new ingredients and new ways to eat them soon spread throughout the capital.

The only thing that made Li Changfeng feel helpless was that he still followed the curfew system, and people had to go back as soon as they were dark.

Night falls, the beginning of the hottest crayfish with beer and barbecue.

But even so, the Beer and BBQ City earned more than 1,000 taels that day, of which crayfish contributed more than half.

This turnover is not high, because many people under Li Changfeng are also eating, so they are free.

The sales on the second day reached a terrifying amount of more than 3,000 taels, and the real daily gain of gold.

The lobsters were consuming at an extremely fast speed, and Li Changfeng had to increase the acquisition efforts, and even increased the purchase price by one cent.

This kind of seasonal business must be done quickly.

Li Changfeng smiled from ear to ear when he looked at the accounts he sent every day. Other businessmen in Beijing admired and envied his ability to attract money.

On this day, Li Changfeng was considering whether to simply make the stir-fried screws, and a guard from the research institute hurriedly came to him.

"Your Highness, something happened at the nuclear weapons research base!"

"What?!" Li Changfeng exclaimed, "What happened?!"

"A building designed by Dean Liang himself to separate and screen minerals collapsed when he tried to install equipment."

Li Changfeng was startled: "Is Liang Dafu okay?"

The guard shook his head: "Director Liang is fine. Two researchers were seriously injured and five were slightly injured."

Li Changfeng breathed a sigh of relief.

Fortunately, Liang Dafu is fine.

If something happened to Liang Dafu, then he would not know when the nuclear weapons plan would be completed. It would definitely be crazy to let him study those things every day.

The collapse of a building must be a problem of building quality.

This is something that Li Changfeng will never tolerate.

No matter who did it, he would never let it go this time.

"Prepare the horse!"

Li Changfeng shouted coldly, walked outside the mansion with a cold expression, and anyone could tell that he was in a very bad mood.

With a fast horse galloping along the way, Li Changfeng came to the nuclear weapons research base.

Looking at the collapsed buildings, Li Changfeng shouted coldly from afar.

"Who built it? Take it back for this prince, immediately!"

Hearing his angry and murderous voice, the people at the scene were startled, and Liang Dafu hurried over to salute.

"Your Highness, don't be impatient and don't make such a big fire. The building is made by ourselves and there is no quality problem."

Li Changfeng was stunned for a moment: "There is no quality problem? How could it collapse?"

Liang Dafu sighed: "That's it..."

After Liang Dafu finished explaining, Li Changfeng sighed and his anger disappeared.

It's not a problem with project quality.

Strictly speaking, it is a problem with building materials.

Most ordinary people in this world are tamped with clay, and their firmness is generally unable to withstand the erosion of rain.

Rich people will use stones to build them with glutinous rice juice. This is the most advanced and most solid construction method at present, and they are not afraid of rain.

The disadvantage is that the cost is very high and generally cannot be afforded by man.

This kind of construction method has a disadvantage, that is, because of the irregularity of the stone, it will be very difficult to build relatively high buildings and cannot guarantee its verticality.

Those strong and high city walls have a slope and are astonishingly thick to ensure their stability.

However, the buildings of the Institute of Science and Technology cannot be built in the form of a city wall, so this situation occurred.

It is very simple to solve such a problem.

First, make the cement out and use a reinforced concrete structure to ensure the stability of the main structure.

Second, fire out the regular-shaped red bricks, and the non-load-bearing part is built with cement mortar and red bricks.

Only by adding a solid foundation can you ensure that there is no accident.

When he was in Baishi City, Li Changfeng thought about getting out the cement, but because he had not found a high-quality large limestone mine, he put the matter on hold.

The walls of Baishi City were also built in traditional ways.

After coming to the capital, Li Changfeng forgot about this, even after the nuclear weapons program was launched, he did not realize it.

After all, this matter was due to his negligence.

Li Changfeng sighed: "In this way, it is true that no one else is wrong. This prince is not considering it carefully enough."

Liang Dafu looked depressed: "What's the use of holding the accountable? Now that we can't even build safe and reliable buildings, how can we implement the nuclear weapons plan?"

Li Changfeng patted Liang Dafu on the shoulder and smiled: "Who said he couldn't build it?"

"Your Highness, do you have a way?"

"I came eight years ago or nine years ago. Do you still remember the cement that the prince once mentioned to you?"

"Cement?" Liang Dafu thought carefully and shook his head, "I don't remember, your highness, you have said too much to me."

Li Changfeng smiled and said, "It's okay, now I will tell you again."

Then, Li Changfeng carefully talked about the raw materials and methods of cement production, and finally focused on its use method and its very strong characteristics.

After he finished speaking, Liang Dafu looked suspicious: "Your Highness, are you not kidding? Even the cannons may not explode? How could there be such a hard thing in this world?"

Li Changfeng smiled and said, "Lao Liang, when did I deceive you? As long as I add steel bars and strictly follow the mark, Daqian's cannon will not be able to explode now!"

Hearing him say this, Liang Dafu was immediately excited.

"Okay! That's great! With cement, these problems are no longer problems. I understand what your Highness you mean. I'm sending someone to find limestone and start developing cement!"

"This matter is not difficult for you. Without solid buildings, the nuclear weapons program cannot continue to advance. You put other things aside and focus on cement."

"I understand, Your Highness!"

After thinking about it, Li Changfeng said again: "Also, it is too costly to build a house with reinforced concrete alone and is inefficient. It is better to use red bricks for non-main load-bearing structures, and the cost is low and the construction speed is fast."

"What is a red brick?"

Li Changfeng continued to explain patiently: "Do you know clay? Red bricks are made of clay, so you have to make clay..."

After he finished explaining, Liang Dafu thought for a while and said seriously: "Red bricks are easy to produce, we don't lack coal, we can make a cave and fire it. As for the regular shape, it's better to make a few iron molds and make them by hand.

Then, when you have time and energy, you will build a machine."

This is why Li Changfeng values ​​Liang Dafu so much and regards him as a treasure.

As long as you give him some ideas and relevant knowledge, he will try his best to trick you out.

The research institute has today, and he has made great contributions.

Li Changfeng patted his shoulder: "Then you can build the brick factory first and put it into production as soon as possible. In the future, our buildings will be built with these new materials, and the amount will definitely be very large."
Chapter completed!
