Seeing that Ou Zhige couldn't wait to study gunpowder, Zhu Ping'an stood up understandingly and said goodbye.

Next stop, Zhang Hong.

The same process, the same routine, the same respect for the wise and the same family affairs, and then inadvertently reveal that he had been in charge of the Hanlin Academy Library, which contains hundreds of firearm classics, as well as the latest, most advanced and most confidential firearm classics developed by the Ming Dynasty, and of course, there are more than a dozen carefully collected firearm classics about Europa, Franchise, and Hongmaoyi.

"More than ten books about firearms about Europa, Flang, and Hongmaoyi?! Can there be artillery?"

When he heard more than ten books of firearms such as Europa, Franchise, and Hongmaoyi in the Hanlin Academy Library, Zhang Hong's hands holding the teacup kept shaking, and the tea was blown out, and his excitement was not inferior to that of Ou Zhige.

He was a man who went to Southeast Asia to steal the artillery of the Red Barbarians. After stealing the artillery of the Red Barbarians for a while, he knew very well that although the Red Barbarians were barbarians and did not know etiquette, their muskets and cannons were far ahead of the Ming Dynasty.

"Of course, there is also a cannon called the Folang machine cannon. The book records that 'the guns and bullets fell like rain and were invincible. The cannon was cast in copper. Because it was cast by the Folang machine people, it was called the Folang machine cannon'. I am quite interested in the Folang machine cannon. Before the Folang machine cannon, my Ming cannon had to be equipped with gunpowder in front and could not be fired continuously. After one cannon was fired, I had to wait for the cannon to cool down. The actual use limitation was quite large. The Folang machine cannon had a sub-gun. When firing, the sub-gun loaded with gunpowder was loaded into the mother gun. After firing, the sub-gun was abandoned and withdrawn. Another sub-gun could be fired. Several sub-guns were quickly replaced, which greatly increased the firing speed, which was of great benefit to actual combat. Oh, there was also a book that recorded a cannon called the Red Cannon, which was more than two feet long and weighed two or three thousand kilograms. It was a few miles apart. It was extremely powerful."

Zhu Ping'an replied without hesitation, and finally mentioned the Red Cannon.

After hearing Zhu Ping'an's words, Zhang Hong was so excited that he could not himself. The Folang cannon described by Zhu Ping'an was completely correct. Moreover, when he was stealing the Red-Fao Yi cannon in the South China Sea, he once saw the "Red-Fao Yi cannon" described by Zhu Ping'an once on the bow of the Red-Fao Yi ship. Although he didn't know that the cannon was called the Red-Fao Yi cannon, the three-meter-long cannon left a deep impression on him. This shows that there are indeed classics about the European, Red-Fao Yi and other foreign cannons in the Hanlin Academy Library.

In order to improve his artillery skills, he could leave his hometown and hang out with Nanyang, steal the lessons of Hong Maoyi to learn artillery making.

Although he racked his brains and tried his best to learn a lot of skills from Hong Maoyi, he was a stealing master after all. Without Hong Maoyi's comprehensive guidance, he still did not learn the skills of the Folang machine cannon and other firearms.

If he had to evaluate it himself, he would have only learned about 50%. The Folang machine cannon he imitated was far less powerful than the true Folang machine cannon made by Hongmaoyi, which made him very unwilling.

Now I heard that there are more than ten classics about foreign firearms such as Europa, Red and Massive Yi in the Hanlin Academy’s library. How can I not be excited?

"Although it's a bit abrupt, I don't know that adults could study these classics at that time, but now I still remember the contents of them."

Zhang Hong asked excitedly.

Zhu Ping'an once again said to Zhang Hong what he said to Ou Zhige, saying that he had a good memory, had a lot of time at that time, and had read it several times, and still remembered about 70% or 80% of the contents.

"I would like to teach me the knowledge about foreign artillery. I, Zhang Hong, only the leader of the adults in this life. If you have something to say, no one dares not to obey."

Like Ou Zhige, Zhang Hong knelt down excitedly, expressed his loyalty to Zhu Ping'an and asked Zhu Ping'an for advice.

The reason why Zhang Hong and Ou Zhige both kneel down and express their loyalty is that they are humble and have no fortune, so they can only sell themselves and rely on others, which is the only bargaining chip they can take.

"Zhang Jiangshi is so serious, please invite him quickly. Zhang Jiangshi is my Zhejiang Army craftsman. I naturally know everything."

Zhu Ping'an helped Zhang Hong up and said what he said to Ou Zhige to Zhang Hong to calm his heart.

"I would like to ask for advice from my elders. I, Zhang, will definitely live up to what I hope." Zhang Hong said with a serious face.

"I have read a lot of content about artillery. It's been so long that I'm a little confused for a while. So I'll talk about it all the time. I'll often come to discuss it with Zhang Jiangshi in the future. I guess the cameras are installed on both sides of the Bolang machine cannon mother gun, which has the function of assisting aiming and increasing hit rate. Zhang Jiangshi must know."

Zhu Ping'an took a sip of tea and said slowly.

"Yes, Hongmao Yi was whimsical, and added photos to the cannon body, greatly improving the hit rate. Our artillery has never had this device, so we can use other artillery in order to increase hits."

Zhang Hong nodded vigorously and replied.

"Yes, some of Hong Maoyi's ideas are still very valuable for reference. For example, it adds a steel hoop to the gun body, which snatches the gun body like a hoop barrel. According to the records in the book, it can effectively imitate the cannon explosion."

Zhu Ping'an gave another example and said.

"Oh, it makes sense. You can add steel hoops to prevent the cannon from exploded. Although it cannot be 100% prevented, it can definitely greatly reduce the cannon explosion." After hearing this, Zhang Hong was deeply inspired and nodded repeatedly.

"About the Folang machine cannon, the latest and most cutting-edge artillery classics in the Ming Dynasty, have also been studied. For the Folang machine cannon, the military battle situation in the capital of the Ming Dynasty has been tested many times, and has innovated several practical results. I can't remember them very much, but I only remembered three points. The first is that the sub-gun must be closely connected to the mother gun; the second is that when aiming with the Folang machine cannon, you must use the three-point and one-line method, that is, the gate, and the sight is connected to the target into a straight line; the third is more practical, and the wooden handle is installed on the sub-gun for easy loading, unloading and fixing."

Zhu Ping'an continued.

"I have also noticed that the Zi Gun is fitted with the mother gun. Three points and one line, the Zi Gun is equipped with a wooden handle, which is worthy of being the military battle situation in the capital. It is indeed well-known." Zhang Hong said with admiration, and he was deeply inspired.

"I won't say much about the surface truths of the Folang machine cannon, adding gun ears to facilitate the transfer of the gun body. There is one thing I want to talk to Zhang Jiangshi." Zhu Ping'an's tone became serious.

"Please teach me, sir." Zhang Hong clasped his fists and bowed deeply.

"More than ten classics of firearms from the Western Air, such as Europa, Flang Machinery, many of which mention artillery diameter technology, saying that it is one of the fundamental principles of artillery, and the making of artillery must follow this technology." Zhu Ping'an said solemnly.

"Architecture Caliber Technology? The fundamental principle of artillery, must it be followed for making artillery?"

Zhang Hong heard the word "cannon diameter" for the first time in his life, and opened his mouth wide in surprise, just like hearing the heavenly book.
