Of course Liu Chan had already guessed Sun Hong’s purpose of coming to Chang’an this time.
Why go to the emperor and surrender is just a delaying tactic by Sun Quan, because Sima Zhao is leading 100,000 Wei troops to attack Hefei at the moment.
At this time, Sun Quan was faced with enemies on both sides.
That's why he made such a choice.
After the dynasty dispersed, Liu Chan went directly to Yuanyang Palace. Zhang Yuan was his queen. Under normal circumstances, he would sit here first after the dynasty dispersed.
While Yuanyangdian and Zhang Yuan were chatting, two young men walked in slowly.
"My son, I pay my respects to my father!"
Prince Liu Chen and King Qin Liu Tan came to the flower hall one after another. It was Liu Chan who sent someone to call them after Liu Chan left the court.
"Chen'er!" Liu Chan looked at Liu Chen and asked, "How did you handle the matter that my father told you?"
This was the reason why Liu Chan called the two brothers here in such a hurry. After Liu Chen heard this, he bowed to Liu Chan and said: "Back to my father, according to my father's will, the production of rocket guns has been accelerated."
Rocket gun?
When he suddenly heard this word, the first person to be surprised was not Liu Chan or Queen Zhang Yang, but King Qin Liu Tan.
What is a rocket gun?
Now the Han Dynasty has begun to use gunpowder. As a prince, Liu Tan certainly knows about this.
However, he did not know the preparation of gunpowder and the refining of various raw materials.
King Qin's doubts did not attract Liu Chan's attention, but he seemed a little excited and agitated when Liu Chen said that production had started and speeded up.
Liu Chan thought about this rocket gun after returning from the Western Regions.
Although the Han Dynasty now possesses the Han Wang Cannon, Liu Chan did not let the Han Wang Cannon appear on the battlefield in this war against Wu. If the Han Wang Cannon was pushed to the battlefield, perhaps Soochow would have been destroyed by now.
The Hanwang Cannon was not used this time. The main reason was that the barrel of the Hanwang Cannon was too heavy. The barrel of a cannon weighed five to six hundred kilograms. Although it was much lighter than the red cannons of the later Ming Dynasty, it was
It's still a bit troublesome to transport a big guy weighing five to six hundred pounds to the battlefield.
After all, now we are just conquering Wu.
Once the Hanwang Artillery appears on the battlefield to defeat Wu, this weapon may soon be known to the people of Cao Wei. Although they are not worried that someone in Cao Wei will imitate it, because they can copy the technology of making cannon barrels, but the cannon shells are
is the key.
Although gunpowder has appeared on the battlefield, there are still only a few people who know about the refining and proportioning of gunpowder. Even among the princes, the only one who knows about the proportioning and refining methods is Prince Liu Tan.
Of course Liu Chan had his purpose in doing this.
Now the territory of the Han Dynasty has expanded, and two powerful kingdoms have been established in the Western Regions.
Now he is naturally not worried that the Tang Dynasty and the Ming Dynasty will threaten the Han Dynasty. The two countries have just been established, and they must be centered on the Han Dynasty. But who can say for sure in the future?
Therefore, in order to ensure the stability of the Han Dynasty in the Central Plains, Liu Chan does not plan to let other kingdoms know about these high-tech technologies that will only be possessed by later generations, but the Han Dynasty can provide them with finished products.
Originally, he thought that Dongwu could be destroyed without using the Hanwang Cannon and using explosive packs. However, Liu Chan also had a backup plan. In the Western Regions, he was thinking that explosive packs could be projected with a three-bow crossbow, but a
There is an explosive pack tied to the spear, but it looks so annoying or inconvenient.
Is there a possibility to fuse bombs and spears?
It’s a cannon that I used to play as a child in my previous life.
If it can be made into a weapon like the Sky Cannon, it may be possible to quickly deploy troops without the Hanwang Cannon for the time being, and it can also greatly enhance the strength of the Han army.
So after returning to Chang'an, Liu Chan began to study this thing.
After several months of research and testing, Liu Chan's research was actually completed two months before the outbreak of the Han-Wu War.
Prior to this, if the Han army wanted to shoot out the explosive package, they had to tie the explosive package to the barrel of the long gun. Although the effect was good, the range was greatly reduced. In the past, the range of a single crossbow could reach more than 600
After carrying the explosive pack, the range is reduced to just over a hundred steps.
Nowadays, Han, Wei and Wu all have three-bow crossbows. Although Wei and Wu are still single-shot, their range is more than 500 steps. If the Han army wants to project explosive packets, they will encounter great risks.<
/p>
Also because of the popularity of the three-bow crossbow, the trebuchets that were commonly used on the battlefield have gradually faded out of the battlefield. After all, its range is too short, only one or two hundred steps, and the maximum is only three hundred steps. This is not the case with the three-bow crossbow.
In front of the crossbow, there seems to be no threat.
Although Liu Chan did not go to the battlefield in person this time, he also felt that the Han army would still encounter some troubles when facing the Wu army. It was also for this reason that when he went on the expedition, he did not prepare a large number of troops and horses for several groups.
Enough explosive packets.
"Let's go!" Liu Chan stood up and said with a smile, "Show me your father!"
"Promise!" Liu Chen agreed upon hearing the words.
Coming out of Wuyang Palace, on the school field in the west of Chang'an City, there were five or six three-bow crossbows, surrounded by fully armed Imperial Guards of the Han Dynasty. Liu Chan, Queen Zhang Yang, King Qin Liu Tan, under the leadership of Prince Liu Chen
Get off and come to the center of the school field.
"Not bad, not bad!"
Liu Chan picked up a special spear. The length of this spear is about the same as that of an ordinary spear. The barrel is made of wood, and the only difference is the head.
About five or six inches away from the gun head, a bamboo tube as thick as a bowl is fixed. The gun shaft is integrated into the edge of the bamboo tube. The bamboo tube is about one foot long and has a two-foot-long lead at the end.
This was something Liu Chan had researched before. Compared with the shells of the Hanwang Cannon, the shells of the Hanwang Cannon are made of fine iron and are as big as the head of a newborn baby. Liu Chan originally planned to use fine iron for this kind of rocket gun.
As for cartridge cases, the war is just around the corner. If refined iron is used, not only will the amount of refined iron be too large, but the production speed will also be greatly reduced.
Bamboo tube, yes, use bamboo tube instead.
The explosives loaded in each bamboo tube are actually more than the shells of the Hanwang cannon, about two kilograms. With some iron sheets and other objects, the weight of this bamboo tube is nearly three kilograms.

It does look similar to the sky cannon he played with as a child in his previous life, so Liu Chan named him Rocket Gun.
There are not many rocket guns on the school field today, only twelve in total.
"Get ready!"
Liu Chen signaled the soldiers to prepare.
A soldier placed a rocket gun in the crossbow card slot of the bed. This still adopts a single-shot design. Whether there will be more shots in the future is left to Prime Minister Zhuge Liang.
"Let it go!"
Liu Chen suddenly shouted loudly.
The rocket gun located in the card slot flew out with a whoosh, and everyone's eyes followed the trajectory of the rocket gun.
Bang——
A crisp explosion sounded in the distance, followed by thick smoke and splashing mud.
"Go over and have a look!" Liu Chan said as he walked forward.
"Four hundred and sixty steps!" Arriving at the location of the explosion, Liu Chan took the last step of tens of thousands, a total of 463 steps. If rounded up, it would be calculated as 460 steps.
The range of the test fire he developed before was 350 steps. Later, he handed over the production to Prince Liu Chen and explained the principles to him.
Unexpectedly, the range of this rocket gun has now reached 460 steps, which is an increase of 100 steps compared to the original range.
!!!
Awesome.
The range of this rocket gun is close to the range of the three-bow crossbow of Wu and Wei, and the destructive power it causes is also very good. The test firing just now caused a pit with a diameter of about one meter in the ground.
Looking at the pit and the shooting range, King Qin Liu Tan was overjoyed and said to Liu Chan excitedly: "Congratulations to my father, my great man has another battlefield weapon."
"Hahaha!" Liu Chan said with a smile when he heard this: "The King of Qin is right!" After saying that, Liu Chan looked at Prince Liu Chen and asked: "Prince, how many rocket guns have been produced now?"
This is Liu Chan’s purpose today.
He personally tested the rocket gun at the school grounds just to test the results of the Prince's production, but when Liu Chan handed it over to him, the rocket gun experiment had been completed and mass production could begin.
Counting the time, it has been almost four months since Liu Chen accepted this task. How many rocket guns has he produced in these four months?
Liu Chan was very curious and looking forward to it.
Because he is in urgent need of a large number of rocket guns.
