After the ammunition was reloaded, the artillery was calibrated, and the gunner shouted: "Ready!" ”

Emperor Qianwu looked at the reinforced concrete wall with a look of expectation: "Open the cannon!" ”

Rumble!

Another thunderclap exploded.

When the smoke cleared, everyone's eyes widened.

In the distance, you can clearly see that there is a large pit on the reinforced concrete, but the overall structure is intact!

Emperor Qianwu's eyes flashed, and he laughed: "Good! All right! ”

The ministers exclaimed.

"This ...... It's even harder than a boulder!? ”

"Something made artificially, in addition to steel, is there something so hard!?"

“……”

At this time, Gu Tiancheng completely understood why Emperor Qianwu deliberately mentioned him when he was leaving, and he deliberately asked his opinion just now.

He couldn't help but exclaim: "The reinforced concrete is so hard, if it is used to build a city wall, how can the enemy be able to fight in?!" ”

Feng Qu was stunned for a moment, then reacted immediately, and said with some excitement: "Not only that, but it is also very suitable to build a flood control embankment, it is so hard, how can the water break it?" ”

Tobe Shangshu then said: "If the cost is low enough, it can be used to build a house, and there is no danger of being washed away by the rain and collapsing!" ”

“……”

For everyone's reaction, Emperor Qianwu was very satisfied.

He laughed and said, "What you Aiqing said is very true, this is the purpose of bringing you to the artillery battalion. ”

Speaking of this, Emperor Qianwu paused and looked at Li Changfeng.

"You made the cement, and you invented the construction method of reinforced concrete structure, so you can tell everyone."

"Yes, Father."

Li Changfeng smiled, and then explained to the ministers in detail the characteristics of cement and reinforced concrete structures, as well as the advantages of red bricks in construction.

In the final analysis, it is not that reinforced concrete is harder than granite, but that it is difficult to blow up the whole piece of concrete because the steel bar pulls the whole concrete. Moreover, it is also because the power of the artillery is not strong enough, if it is replaced by those shells in the previous life, it will be a matter of minutes to explode.

When the ministers heard this, they were all shocked.

Gu Tiancheng felt that the opportunity for the Ministry of Industry to show his strength had come, and said excitedly: "Okay! That's great! We can build strong walls and embankments with reinforced concrete, so that the cities will be impregnable and no longer afraid of evil beasts, and the rivers will no longer be a calamity, and the people will be protected from a good harvest! ”

Emperor Qianwu nodded with satisfaction: "That's right, these projects will be gradually advanced in the future, and Gu Aiqing must prepare early." ”

"Yes, Your Majesty!"

Feng Quji exclaimed: "His Royal Highness the Ninth Emperor Prince has made great achievements for my great cadres again, the old minister admires it!" ”

As he spoke, Feng Qujian actually bowed deeply to Li Changfeng.

Li Changfeng hurriedly helped Feng Qujian up.

"The old prime minister doesn't have to be like this."

As soon as he helped Feng Quji, the other ministers bowed down one after another.

"Cement is of great significance, and His Highness has made great contributions!"

"From now on, glutinous rice syrup will no longer be used in the construction of the city wall, and many people will no longer starve, which is a great merit!"

“……”

Everyone exaggerated for a while, and Li Changfeng was a little embarrassed.

Li Changfeng's prestige in the hearts of the ministers can no longer be shaken.

Emperor Qianwu looked at this scene, and there was no trace of dissatisfaction in his heart, but he was extremely pleased.

In the future, there will be no resistance to handing over the cadres to Li Changfeng.

After a while, when everyone was quiet, Emperor Qianwu advised: "The output of cement must be raised, and I plan to rebuild the palace wall, so you must prepare early." ”

"Yes, Father."

"Drive back to the palace."

When Emperor Qianwu returned to the palace, the ministers could not stay in the artillery camp, so they had to leave.

Before leaving, there were many ministers who came to ask when the cement would be on the market, what the price would be, and so on.

Li Changfeng said that the time to market is uncertain, and the price is also uncertain.

He has no plans to sell the cement at this time.

The demand for cement is very high in the nuclear weapons research institute and other industries, and the Qianwu Emperor is going to build the palace wall, so the current production capacity is somewhat stretched.

It will not be sold until the construction of a larger and more advanced cement plant is completed and put into production.

With red bricks and cement, the construction work of the Nuclear Weapons Research Institute was in full swing, and Li Changfeng was finally idle.

He sleeps until he wakes up naturally every day, drinking beer and eating crayfish, and the days are called a beauty.

However, such days only lasted for three days, and Li Jianye sent someone to send news that he had been asked to come over for inspection after the formation of the Air Force had been completed.

According to the plan, the number of hot air balloons in the Air Force should reach 500.

With such a number of hot air balloons flying into the sky, Li Changfeng felt a little excited when he thought about it.

Li Changfeng rode a fast horse and galloped all the way to the air base.

Li Jianye was already waiting at the door, and when he saw him, he hurriedly greeted him, and said with a look of resentment: "Brother Jiu, you are finally here, if you don't come again, I can't help but take off with my subordinates!" ”

Li Changfeng scolded with a smile: "If you dare, I will remove you from your post and send you to repair the railway!" ”

Li Jianye knew that he was joking and didn't take it seriously, so he explained as he walked.

"Among the 500 hot air balloons, except for the 100 made in JYG, the others are made in the capital, the materials are better, the weight is lighter, the load capacity is greatly improved, and they can carry more fuel and ammunition......"

Li Changfeng's mind was not on his words, looking at the five hundred neatly arranged hot air balloons, and the soldiers standing on the side with anticipation on their faces, he interrupted his words with words.

"Alright, stop talking nonsense!"

Li Jianye obediently shut up.

Li Changfeng took a deep breath, shouted loudly and ordered: "Daqian Air Force, prepare to take off!" ”

……

The other side.

A convoy is heading in the direction of the capital.

These men were dressed strangely and were a little different from the great cadres, and each carriage was filled with large boxes, which could be seen from the struggling appearance of the horses, and the contents of the boxes were very heavy.

This team is none other than Park Kyung-tae, who came to deliver silver to Lee Changfeng.

After he went back with penicillin last time, after learning that the price of penicillin was ten taels of silver, he reprimanded him severely.

However, when the king of Goryeo learned that the price of the sale to the Wako Kingdom was 20 taels, his mood became a little better.

In his view, Li Changfeng's move showed the friendly attitude of the great cadres towards the Goryeo State.

Combined with the fact that the Japanese had invaded the waters of the Great Dry and that the Goryeo Kingdom had never provoked the Great Dry, the King of Goryeo felt that this was a great opportunity to establish friendly relations with the Great Dry.

After establishing friendly relations, we will find a way to get such things as artillery and musket grenades from Daqian, in order to strengthen Goryeo.

Park Kyung-tae came this time, in addition to giving money to buy penicillin, the most important thing was to tie up with Li Changfeng.

This is because Park Kyung-tae has inquired clearly, artillery, muskets, and grenades were all invented by Li Changfeng and made by him, and they have a pivotal position in Daqian and can influence Emperor Qianwu's decision-making.

"When will my Goryeo Kingdom be as powerful as Daqian!"

Park Kyung-tae looked at the majestic city wall in the distance and sighed.
