Yang Xuan determined the strategy in a few words, but the tactics still needed to be discussed.
Make friends with the princes and bundle their interests. How to make friends with them and how to bundle their interests?
Theoretically, all the princes are shareholders of Shengfa Company, and their interests are already tied up.
But when it comes to the throne, this little benefit may not be enough to make them have any scruples.
To be precise, no matter how great the benefits are, they cannot be compared with the throne. After all, as long as you are on the throne, no matter how many benefits you have, you can put them in your pocket.
Therefore, there is a need for a sharp weapon that can influence the struggle for imperial power, so that the princes will be afraid and not dare to take drastic actions.
To reach this level, it cannot be achieved by relying on economic interests alone.
The only thing Yang Xuan could think of was deterrence by force.
But for deterrence by force, just rely on the two brothers Dong Tianbao and Zhang Junbao?
Even if all Taoist priests from Laojun Guan, large, medium and small are included, it is still far from enough.
At this point, all he could do was use the firearm that he had been unwilling to involve.
The Dasheng Dynasty also had Shenji Camps with firecrackers and artillery.
However, judging from the size of Shenji Camp, the power of Dasheng Dynasty's firearms may not be satisfactory.
After all, before Yang Xuan, the Dasheng Dynasty didn't even have high-strength steel, let alone the design accuracy and range of the firecrackers.
Of course, Yang Xuan also didn't understand how to improve the firing rate, range and accuracy of the musket.
But in his opinion, there is no need for such high-tech things for the time being. He only needs a shocking firearm.
So the best choice is a grenade. Although with current technology, it is impossible to be small in size yet powerful, that doesn't matter.
As long as it's powerful enough, it doesn't matter if it's bigger.
"Brother Lu, give me three days, and by then there will be a way to break the situation."
His Royal Highness King Chun was overjoyed when he heard this.
Mr. Lu asked doubtfully: "May I ask Mr. Yang, what is the way to break the situation?"
"Don't be anxious, we will know when the time comes."
Mr. Lu was still waiting to ask again, but His Royal Highness King Chun said: "I believe sir, if he said there is a way to break the situation, it will definitely work."
Mr. Lu felt a little sad. He was a talented person from Linchuan and had been involved in strategy for more than 20 years, but today he was outclassed by a boy with a bunch of hair?
But in the current situation, he couldn't think of any clever plan, so he could only take it as he saw it.
Yang Xuan also saw Mr. Lu's lonely expression, and immediately said: "In the past three days, if the princes make any move, it will be up to Mr. Lu to deal with it."
Mr. Lu was suddenly startled. Is the person in front of him really a seventeen-year-old boy?
After bidding farewell to His Royal Highness Prince Chun, Yang Xuan went straight to the Nanshan Mine.
Whether the large grenade he had in mind would be successful would depend on landing on a person.
This person is Qin Laohan.
Qin Laohan used to be a tomb robber. In order to dig the tomb, he needed gunpowder.
There are often completely sealed solid structures in underground palaces. If you want to open them, you can only use gunpowder to explode them.
Qin Laohan's father was good at this, but ordinary gunpowder was too weak, so his father developed an oil mine.
What exactly is an oil mine? Yang Xuan didn't understand what Qin Laohan said. He just knew that this thing is like oil and water, but it is very unsafe and will explode if it collides.
It was precisely because of this that his father accidentally blew up the tomb passage and was buried in the tomb.
Later, Qin Laohan worked hard on the basis of his father's research and developed a safer explosive, which was to soak the oil in the oil mine into a material he called collodion, which could not only ensure safety, but also make explosives more explosive.
It will not reduce its power, and it can be regarded as making up for the original regret.
Later, when the mine was opened, Qin Laohan used this kind of thing.
Yang Xuan knew at that time that if this thing was developed, it would be equivalent to Pandora's box. Once opened, it would be a catastrophe for mankind.
So Yang Xuan warned Qin Laohan that he must never use this thing again, otherwise it would lead to death.
Qin Laohan had already obeyed Yang Xuan's orders and would never use them again.
Now, Yang Xuan is ready to open this Pandora's box.
"Qin Laohan, take your meal guy and follow me."
Qin Laohan was confused: "What kind of guy is eating? His head?"
One look at Qin Laohan's look, and Yang Xuan knew that he had gone astray, and quickly explained: "It's about you making the oil mine."
"Oh." Qin Laohan patted his chest. He was startled by Yang Xuan's serious look just now. He quickly packed up and got on Yang Xuan's carriage.
Qin Laohan threw a bag of things on the carriage with a clang, which shocked Yang Xuan: "There are no oil mines here, right?"
"Don't worry, shopkeeper, these are all trivial things." Qin Laohan said with a silly smile: "Besides, the oil mine I made is very stable and will not explode unless exposed to an open flame."
Yang Xuan nodded, and then asked the driver to go all the way to the technology research and development department.
His current coachmen have been replaced by Dong Tianbao and Zhang Junbao. In this situation, with these two masters, Yang Xuan feels more at ease.
When he arrived at the technology research and development department, Yang Xuan directly asked shopkeeper Qian to arrange a secret and safe place.
From the day it was established, the Technology R&D Department has been a highly confidential place, half at the foot of the mountain and half on the mountain. Seeing that Yang Xuan was so nervous, shopkeeper Qian directly arranged for Yang Xuan to go to the secret No. A yard on the mountain, which has the highest level of confidentiality.
This is a cliff. There is only one way to go up. The intersection is guarded by special people. It is impossible to sneak past. Even if someone breaks in, an alarm can be sounded.
Once the alarm sounds, there will be a Beijing camp stationed less than ten miles away, and the entire technology research and development department can be surrounded in the time it takes a stick of incense.
"Old man, you can make that oil mine now, but you don't have to put it in a bamboo tube."
"okay."
Then Yang Xuan took the two treasures down the mountain, found shopkeeper Qian, and asked him to send someone to make a hollow ball.
Shopkeeper Qian was a little confused: "What kind of hollow ball?"
Then Yang Xuan explained, drew pictures, and told shopkeeper Qian the large grenade shell he imagined.
Shopkeeper Qian looked at it for a long time: "Isn't this just a jar?"
"Yes, yes, it's just a jar, but it should have a triangular pattern like this on it. There are three sizes: large, medium and small. I'll make ten of each type first. I need them urgently."
"What grade of high-strength steel should be used?"
Yang Xuan thought for a while: "Just use No. 9."
"No. 9?" Shopkeeper Qian said, "Although No. 9 is hard, it is too brittle."
Yang Xuan thought for a moment and thought that transportation safety might need to be involved in the future, so he changed his mind and said, "Then use No. 7."
Shopkeeper Qian left in response.
Because Yang Xuan can always come up with some whimsical ideas, once these ideas are successfully developed, they can have unexpected functions. The craftsmen involved in the research and development can receive large sums of silver rewards, so it has formed a habit. As long as Yang Xuan is
If you tell them, they will do it unconditionally.
Although shopkeeper Qian didn't know the use of using No. 7 high-strength steel to make such small jars, he still made arrangements immediately.
When the craftsmen at the blast furnace heard that it was the task given by Yang Xuan, they all started working immediately as if they had been given a shot of blood.
After all, this thing has no technical content at all.
