Historically, the advent of the Nimi rifle made the rifle surpass artillery as the decisive weapon on the battlefield at that time.

But there are some problems that cannot be solved with the Mini bullet, according to Sun Heding, this new type of bullet can only be made of very soft metal materials, such as lead, so that the warhead can easily expand.

In addition, the requirements for propellant are relatively high, and it is necessary to use fast-burning gunpowder in order to rapidly expand the warhead to lock the chamber.

Sun Heding said his shortcomings unreservedly, and wanted to ask Zhu Cihong for a suggestion, he knew that this prince had a wonderful idea for firearms.

Zhu Cihong waved his hand and said: "These problems are not big, just spend money to manufacture, you don't have to worry about the cost, the future trend of the development of our army's firearms is to fill the medicine from behind, and the problem of bullet primer that this palace told you before should be studied as soon as possible." ”

The reason why the historical Mini rifle is not famous is because it was replaced by breech guns not long after they came out, and the appearance of breech guns made the cavalry lose its meaning of existence.

Zhu Cihong said again: "The new musket you developed is called the Heding rifle!" ”

Sun Heding was grateful, and the crown prince has always attached great importance and respect to his researchers, and his research and development meritorious service is also like a general in the army.

The surrounding scientific researchers were even more moved, most of them were craftsmen, many people did not take them for granted before, but now the crown prince not only gave himself land, gold and silver, but also abolished the craftsman registration, giving himself the opportunity to become a master.

Throwing in a peach and repaying it with a li, the researchers of the institute are more willing to work for Zhu Cihong with all their hearts.

Next, Zhu Cihong watched the testing of several new weapons, one of which caught his special attention.

A researcher modified the Divine Fire Raven to develop a new type of rocket that could not only maintain flight stability, but also have a range of more than three miles.

The Divine Fire Crow is a military rocket standing in the Ming Army, the appearance is like a crow, made of thin bamboo or reeds, filled with gunpowder, and two rockets are mounted on each side of the crow's body.

When launched, it is pushed forward by the reaction force of the rocket, and can fly 300 steps, and the gunpowder contained inside the crow is ignited and exploded when it lands.

However, the Shenhuo Flying Crow is not stable, flying in the air when launching, it is difficult to accurately hit the target, it is okay to play in a group, but it is not good to be on the single and jungler.

With the West's Congreve rocket, although the Divine Fire Raven can kill and injure the enemy on a large scale, the damage to his own people is not small, and he may fly back in the sky to blow up his own people.

In the Battle of Waterloo, Congreve rockets were not fired from artillery, and Napoleon suffered greatly with their superior mobility, but Wellington said: "Although this pit helped us win the war, our rockets were more of a threat to me than Napoleon's artillery.....

It can be seen that Wellington, who uses Congreve rockets, has been tossed a lot himself.

A researcher from the Research Institute of the Jiangnan Ordnance General Administration successfully solved the problem of the Divine Fire Flying Crow flying indiscriminately, and he made improvements to the Divine Fire Flying Crow, directly removing other bells and whistles on the crow's body, and opened three small holes in the tail of the cylindrical cartridge, and installed three inclined and stable spiral plates.

When the rocket is launched, the gas removed from the small hole in the tail rotates the rocket under the action of aerodynamic force, so that it flies straight, so as to achieve a stable effect, just like the effect of the arrow feather.

Zhu Cihong sighed secretly, isn't this the Hall rocket in history?

In the test firing range, the sizzle of the firing line, a ball of orange fire rose, and in the swishing sound, rockets with flames continued to fly into the sky.

Seeing the big rocket dragging the flames and white smoke flying out, everyone couldn't help but look up, and Zhu Cihong's heart was even more shocked, as if he had seen the missile launch scene in the army in later generations......

Zhu Cihong thought to himself, the ancients did not have to be stupid in later generations, on the contrary, even smarter, in addition to the Divine Fire Crow and the Fire Dragon out of the water, the Ming Dynasty also had a primitive rocket - the Heaven-Shaking Thunder Cannon, which could rely on its own charge to burn and propulsion.

The world's rocket technology originated in China, China was already able to manufacture rockets propelled by gunpowder in the Song Dynasty, and rocket weapons have been greatly developed in the Yuan and Ming dynasties.

China's rocket technology was introduced to India in the Yuan or Ming Dynasty, and was quickly imitated and improved by the Indians, and later Britain, France and other countries invaded India, and were greeted by the Indian army with rockets, causing heavy losses to the British army.

After the conquest of Mysore, the British brought the captured rockets back home, and during the Napoleonic Wars, William Congreve, an artillery colonel working in the Royal Laboratory, improved the Indian rocket and created the Congreeve rocket.

Later, the British made simple improvements to the Congreve rocket, creating the Hall rocket, which greatly increased the accuracy, and was used from the American Civil War to the American and Spanish Wars.

Zhu Cihong said to the craftsman who developed the new rocket: "What's your name?" ”

The craftsman was in his forties and dark-skinned, and he said worriedly: "The villain's name is Li Dongfeng. ”

"Li Dongfeng? What a name! Zhu Cihong sighed and said, "The rocket you developed is the Dongfeng rocket!" ”

Li Dongfeng's mood suddenly stirred, and he couldn't help choking up, the person who is a confidant dies, what can the husband say?

Zhu Cihong ordered someone to take pen and ink, and he swayed freely, and wrote eight big characters on the rice paper: "Dongfeng Express, the mission must be achieved!" ”

Zhu Cihong handed it to Li Dongfeng and said, "Continue to work hard, strive to develop more powerful rockets, make a Dongfeng series of rockets, let them shoot at the enemy camp, and clear all obstacles to the enemy for my Ming Dynasty!" ”

Rockets are an indispensable weapon in future warfare, it does not require heavy artillery fire, it is flexible and changeable in combat, and has the ability to strike accurately, and it is a terrifying attack weapon for the enemy on the battlefield.

The Dongfeng rocket newly developed by the research institute is not very technical and very simple to build, and it can be installed on a large scale.

Li Dongfeng excitedly held this ink treasure, his eyes were slightly red, and he said solemnly: "Your Royal Highness the Prince, rest assured, the villain Li Dongfeng will definitely work hard to develop more and stronger rockets for Daming!" ”

Zhu Cihong nodded and said: "In the future, as long as someone researches a new weapon, it will be named after each other, as long as the things you research can play a huge role on the battlefield, this palace will also give you a marquis title as a meritorious service!" ”

Hearing this, the researchers were even more excited, and even Sun Heding was moved.

Just now, Xu Sheng told him that the crown prince had rehabilitated his father Sun Yuanhua's case, and that he could return to Beijing at any time to move Sun Yuanhua's tomb back to his hometown of Shanghai County.

Zhu Cihong and his entourage came to the compound of the research institute not far from the test site, which was full of discarded drawings, and there were a large number of strange weapons everywhere in the courtyard, and there were research freaks everywhere.

Looking at the simple environment around him, Zhu Cihong decided to move these elite military craftsmen to Nanjing, and establish a military research institute in the eastern suburbs of the Forbidden City to give them the best conditions.
