"Your Majesty, the last time our people saw Huang Taiji was on June 24th. It has been ten days since then."
After Li Ruolian responded, he thought for a while and then said: "But recently, it seems that Mang Gurtai, Azige, Yue Tuo and others are no longer in Shengjing."
"Ten days?"
Chongzhen frowned slightly and said, "Where are the slave-building coalition forces?"
"Five days ago, the slave-building coalition forces rested and reorganized at a place more than 200 miles away from the Karaqin tribe. In the past two days, they suddenly expanded the warning range by 100 miles.
We are afraid of being exposed, so we can only conduct a single-line investigation. I don’t know what is happening with the Kalaqin Department at the moment! "
After listening to this, Chongzhen looked thoughtful.
Huang Taiji was not in Shengjing, the coalition forces expanded the warning range, and various man-made disasters within the Ming Dynasty distracted the court's energy.
After a while, Chongzhen said to himself: "They are coming!"
"Yes, they're about to start!"
"I'm probably waiting for an opportunity. This opportunity may be when Kong Xingxie comes to Beijing and forces me to issue an edict to punish myself, because that's when morale is at its lowest!"
"It is possible that we are waiting for reinforcements from various ministries to gather, but this is unlikely!"
"What a good plan!"
Chongzhen muttered to himself a few times, and Li Ruolian listened intermittently, but he knew from few words that the emperor must be plotting against Huang Taiji.
"Li Aiqing, continue to keep an eye on Jiannu and Shengjing. If there is any change, report it quickly!
In addition, secretly send people to sneak into Xifengkou, Da'ankou, and Longjing Pass hundreds of miles away. If there is any movement, report it immediately! "
After Li Ruolian left, Chongzhen looked at Wang Chengen: "Sign up with the Firearms Research Institute and streamline your entourage!"
Under the escort of more than a hundred elites led by Zhou Yuji, Chongzhen arrived at the checkpoint outside the Firearms Research Institute half an hour later.
Following the last reminder, this time the inspection was even stricter. Even Chongzhen did not escape the body search, but it was Xu Guangqi who was searched.
Naturally, I came to the Firearms Research Institute to see how many palm mines have been made and how they have been improved. After all, this is for
In the meeting hall, Chongzhen sat at the head of the table: "Xu Aiqing, how many granulated gunpowder and palm thunder are there now?"
"Back to Your Majesty, the process and technology of granulated gunpowder are now relatively mature, and the daily production of granulated gunpowder is more than 300 kilograms regardless of cost.
As of last night, a total of 13,000 kilograms had been produced, with a total of 20,000 half kilograms of palm thunder, and the remaining three thousand kilograms were all made into thunder! "
"Thunderbolt? New firearm?"
"It's the kind of firearm that your Majesty mentioned last time, using a jar to make a trebuchet. We have made a new breakthrough and finally named it Hongtian Lei.
Because this firearm is similar to the Thunderbolt and the Thunderbolt, it is called the Thunderbolt.
Now all the products are made in ten-pound packages. "
"Let's go to the testing ground!"
Hearing that it had been improved, Chongzhen was very happy and stood up to go to the testing site.
Xu Guangqi waved his hand, said a few words to Sun Yuanhua, and quickly followed him.
In the valley where the test site is located, Chongzhen held the improved palm thunder and was filled with emotion.
Even though he did not draw the shape of later grenades, the Zhentian Lei improved by Xu Guangqi and others still looks similar to later grenades.
"Your Majesty, the entire palm thunder weighs one pound, including six taels of gunpowder, two taels of lead, and two taels of shape. They are all added with sugar. It is more powerful than the previous test."
After introducing the palm thunder, Xu Guangqi asked someone to bring in something similar to the explosive bag of later generations.
"Your Majesty, this is the thunder. Put the animal skin in a wooden box, shape it with thin iron sheets on the four sides, add gunpowder, and compact it...
The full weight of the thunderbolt is fifteen kilograms, and its gunpowder is ten kilograms. The explosion radius is five to ten feet, and there will be no survivors within a three-foot radius.
There were missing arms and legs in a radius of five feet, and there were internal injuries. Ten feet was the maximum range of the blast wave, and the trebuchet's projection distance was fifty feet. "
As Xu Guangqi spoke, he took a few cotton balls and handed them to Chongzhen: "Your Majesty, put them in your ears. The explosion will be loud after a while."
Seeing that the emperor was ready, Xu Guangqi commanded several sergeants to place the thunderbolt on the trebuchet.
Chongzhen and others watched from behind the bunker as the thunderbolts were projected across an arc and fell into the distance.
boom!
The violent explosion, accompanied by fire and smoke rising into the sky, echoed in the valley.
Chongzhen, a man who thought he had seen the world in later generations, felt his head was buzzing at this moment. The explosion was too violent.
Not to mention the Fang family and others who were escorting him behind him, all of them had incredible expressions on their faces.
They really want to ask Xu Guangqi, do you have a misunderstanding about the louder explosion?
When the smoke dissipated, Chongzhen arrived at the explosion site. A large pit with a diameter of one foot and a depth of three feet in the center appeared. The bottom of the pit was scorched black.
Looking at the fragmented special scarecrows used for experiments, Chongzhen was very satisfied.
Used well, it's an absolute killer.
No matter how many people were admitted to the prison this time, they had to be beaten to death.
"Your Majesty, I have tested that if the checkpoint outside the Firearms Research Institute is placed permanently, four or five people can blast a gap.
If it is a trebuchet projectile, it will take thirty to fifty to completely destroy it if it hits the level! "
hiss……
Everyone gasped and gasped again in horror.
You must know that the outer barrier between two mountains is ten feet wide, three to four feet high, and three feet thick. It can be destroyed by thirty thunderbolts.
Just ask, how many big cities have walls that can withstand it?
But the enemy is not stupid either. If there are arrow masters like Tiger and Tiger who can kill one stone five times, with the distance of a trebuchet, they can really name them one by one.
Even if there is no such master of archery, the distance of fifty feet is still within the attack range of Crouching Tiger Cannon, General Cannon, etc.
Therefore, even though it is so powerful, it can only be taken by surprise.
"Xu Aiqing, you are ready with Palm Thunder and Thunder Sky Thunder. In a few days, I will ask Sun Chuanting to personally bring someone to hand over.
The black powder produced in the future will all be made into palm mines, ready to be handed over at any time! "
After bidding farewell to the Firearms Research Institute and returning to Dongnuang Pavilion, Chongzhen felt much more relaxed. The data given by the Firearms Research Institute made him feel at ease.
Judging from the current situation, Huang Taiji is probably waiting for Kong Xingxie to come to Beijing to force him to issue a sinful edict.
Qufu is only more than a thousand miles away from Beijing. Calculating the distance, Kong Xingxie can enter Beijing in ten days at most.
If that couplet reaches the Kong family, maybe Kong Xingxie will go home directly.
If you insist on going your own way and insist on entering Beijing, you should avoid it and be more firm. If the plan cannot be implemented, then Jiannu will have no choice but to enter the country by force.
Based on this calculation, Jiannu entered the customs within half a month.
Thinking of this, Chongzhen felt excited.
After a while, Chongzhen called for Li Ruolian and delivered several letters in succession.
