The First Family of Tang Dynasty

, the fastest update of the first family of the Tang Dynasty! When Cheng Saburo and the other group rushed to Luoshui'an in the dark, Li Ke, His Highness King Wu, who liked to watch the fun the most, naturally jumped over.

When I came to the Luoshui River, which was ten miles away from Chengjiazhuang, the Luoshui River was very quiet at night.

The torches illuminated the open space on the river bank very brightly, and Cheng Saburo began to direct his men to start digging holes on the river bank.

It is even strictly required that the angle must be forty-five degrees, and the depth of the soil hole must be at least enough for half of the metal barrel to be buried in the soil.

As for why to do this, it is very simple, a fixed angle, which is convenient for later ballistic calculation.

As for why at least half of the barrel was buried underground, it was because of whether this thing was insured, safe or not, Cheng Saburo knew the shit.

He only knew about such a gunpowder ejector in museums and on the Internet, not to mention, whether it is propellant or explosive pack, it is not the standard of later generations.

So he has no idea in his heart. If it explodes directly in the barrel, wouldn't he die before he succeeds in his apprenticeship?

Think about yourself being eighty... oh no, there are old and young, so you can't put yourself in just to make some new inventions.

There was excavation over there, and Cheng Sanlang watched the Cheng family carefully take down the propellant and explosive packs.

For the sake of insurance and safety, Cheng Chubi finally did not choose nitrocellulose as the propellant, but black powder as the propellant.

As for what was wrapped in the explosive bag, of course, it was the nitrified explosive after passivation. Considering that tomorrow, it would be one of the best fortified cities in the world, not the pre-buried explosives.

Cheng Chubi gritted his teeth, stomped his feet, and ruthlessly, and added a little white sugar that was as sweet as honey into the nitrifying explosive.

I remember that when I was a child, I was tired of frying cow dung with firecrackers, so I thought about going to fry fish ponds, but soon I found that the power was not enough, so I added sugar to make it up. This is only a veteran of firecrackers, and has rich and outrageous blasting experience. .

In addition, it is necessary to have an assiduous research spirit and an attitude of excellence, in order to be able to find this means of increasing power in countless failures.

Even Cheng Saburo didn't add the black powder before, uh... I really forgot at that time. Afterwards, considering that the black powder formula he took out was already very powerful, he didn't continue to add some sweet as honey.

And in order to ensure that the propellant below is ignited to the greatest extent, it will not detonate the explosive pack above, but only ignite the lead of the explosive pack.

Cheng Chubi had a brainstorm and found a good way, that is, he took a round thin wooden board and placed it on the propellant, and separated the propellant from the explosive pack of poor quality.

After the propellant is ignited, the pressure of the explosion of the gunpowder will cause the thin board to fly up, and even the explosive pack will fly out together, and the lead of the explosive pack extending below the thin board will also be ignited.

In this way, there is no need to consider other detonation methods.

Inside the large tent of the Zuotunwei Central Army, there was a sudden screeching noise.

The prince Li Chengqian, who was sitting in the first place, had already stood up and looked at the head of the Zuotunwei Ranger with disbelief.

"Are you sure?" General Cheng strode directly to the head of the ranger who came to report the news, and shouted with wide eyes.

The leader of the tour quickly replied loudly.

"How dare the last commander dare to talk nonsense, as far as the last commander saw, he saw Duke Ju and Sun Fujia, the minister of Dali Temple..."

"There are a total of one hundred and thirty-seven officials, and there are also Luoyang officials and prisoners who protect them all the way to the east."

"Ah, this..." Cheng Yaojin grinned and couldn't help but let out a loud voice.

"Old Cheng was still thinking of building a headgong tomorrow, but he didn't expect that this headgong would be delivered to the door by himself. What is this special mother, a blind cat hit a dead mouse?"

As soon as General Cheng's remarks came out, the rough old men who were in Zuotunwei were beaming and laughing.

"..." Li Chengqian, Yu Zhining and Henry Zhang are a bit involved. After all, whether it is a blind cat or a dead mouse, they are not willing to be.

"Oh, this is really God's blessing to the Tang Dynasty. When His Royal Highness came to the outskirts of Luoyang, he encountered such a good thing."

Such meritorious deeds, if you don't do it well, isn't it too sorry for His Royal Highness the Crown Prince?

Yu Zhining, who didn't know whether to be a blind cat or a dead rat, couldn't care less, and went straight to General Cheng to give a salute.

"Congratulations to General Cheng, and it is really gratifying to congratulate the little Cheng Taibao for another extraordinary achievement."

"Those ministers have been detained in Luoyang's prison all the time, and then they have been bumping with the boat all the way, they must have suffered a lot.

General Cheng, the lower official thinks, should we respectfully invite His Royal Highness together..."

Seeing the wink from Yu Zhining, the father of the prince's best friend, General Cheng naturally knew the elegance by hearing the song.

He personally went out to protect His Royal Highness and went to the shore of Luoyang to meet and comfort those loyal officials of the Tang Dynasty who had suffered for many days.

The more than 100 people have not seen the sun for a long time, and then sat on the boat again, worrying about the loyal ministers of the Tang Dynasty for almost a whole day.

When he saw that His Royal Highness, the prince who was said to have made Jiangnan into a sea of ​​corpses, he was standing on the shore at this moment, his smile was so friendly, and his tone was so kind.

It moved all the ministers to tears, and even how they looked at them on weekdays felt very unpleasant to the eye, and the notorious General Cheng became more beautiful and pleasing to the eye a lot.

After the metal buckets are all buried, the next step is to charge the charge, hold the partition and the explosives inside...

Looking at Cheng Sablang's operation, Li Ke always felt a sense of trembling. Brother Bute revealed the general meaning, that is, he wanted to use black powder to shoot out the package of explosives.

And shoot farther than a bow and arrow, and let those explosives explode in the distance.

Although Li Ke always felt that it was a little unreliable, but brother Hebi swore that he would definitely do it, Li Ke could only wait quietly for the development of the situation.

After the installation was finally completed, Cheng Chubi stood up and looked at the river bank directly in front of him. There were all river beaches in Dali Xu, and there were no trees to cover them.

"Everyone, step back, step back a hundred paces away." Following Cheng Saburo's order, everyone, including the inner guards, all retreated to the rear.

Cheng Saburo squatted down, lit the lead wire, twisted his **** and ran towards the back.

Not too long, he also ran a hundred paces away, stood still in the crowd, took a deep breath, and looked at the flying thunder cannons that were illuminated by torches nearby.

Because of the first test shot, the lead was left relatively long, so everyone could only wait anxiously for the time to pass bit by bit.

Then, everyone heard a dull roar, and then saw fire and smoke spurting out of the mouth of the metal barrel.

A dark shadow flashed past, and the thin wooden board quickly fell to the ground, but the explosive was packed in such a dark night, and it was impossible to know where it flew.

Everyone stood there dumbfounded and waited for a long time. Li Ke, who stretched his neck, couldn't help but put his elbow against Cheng Saburo.

"Brother Chubi, do you really rely on this stuff?"

Cheng Chubi stretched out his hand, scratched his chin and muttered in a low voice.

"Reliable is definitely reliable, but I just don't know if the lead has been ignited, or if the lead is left too long..."

"boom!!!!"
