Chapter 894

In the history of human hot weapons, black powder is the beginning of the era of hot weapons, but strictly speaking, the power of black powder is not great.

In terms of physical data, the explosion speed of black powder is only 500 meters per second.

The TNT explosive of later generations, with an explosion speed of 6920 meters per second, nitroglycerin at an explosion speed of 8 kilometers per second, and C4 explosive at an explosion speed of 8040 seconds, can turn black powder into slag in seconds.

Therefore, strictly speaking, the explosive package made by Niu Wu is not very powerful, at least much less powerful than the explosive package used by the Eighth Route Army during the war of resistance against Japan.

But even so, when the explosive bag made of eight or nine kilograms of black gunpowder showed the power of hot weapons to mankind for the first time in the world, its huge roar and explosive power still stunned everyone present.

On the training ground, accompanied by the roar of a thunderbolt, the fire suddenly appeared, and the shock wave generated by the explosion directly blew up the Loess on the training ground, raising huge dust columns on the ground.

After the explosion of black gunpowder, a huge black smoke soared into the sky.

The huge sound produced by the explosion made people's ears roar and hum.

Li Qieyou was smart. As early as the Yamen lit the fuse, he covered his ears with his hands and opened his mouth to offset the shock wave caused by the explosion.

Therefore, when the explosive package was detonated, he was the first to recover.

In fact, the explosion of the explosive bag also shocked Li forget worry.

After all, in future generations, in addition to seeing the explosion scene in movies and television, where did he have the opportunity to really feel the shock brought by the explosion from a close distance.

As for Niu Wu and Zhang Jia brothers, they also opened their mouths and looked frightened.

Originally, in their eyes, it was just an explosive package of "large explosive rod". After ignition, it would produce such a violent explosion, which naturally surprised the three.

This kind of explosion shock like thunderbolt and thunder finally made the three people believe that what their husband asked them to make is really not a toy explosion rod, but a "Thunderbolt and thunder" that can be used to kill!

Dugu Feng, the magistrate of Jiulong County, stared at the smoke column rising from the explosion and couldn't speak for a long time.

The several yamen servants who followed Dugu Feng's back all knelt down and tried their best to kowtow to the location of the explosion.

In their opinion, there is no other explanation for such a furious anger except the legendary immortal magic.

The Yamen servants looked at Li forgetful, and they were even more afraid and awed.

Li forgot to worry, but he couldn't help laughing.

The power of the explosive bag was completely in line with his imagination.

In this way, as long as there are explosive bags in hand, are you worried about those bureaucrats besieging the city?

I'm afraid that when those bureaucrats attack the city again, they will throw a few explosive bags down and blow up a group of people. After killing a group of people, they will frighten the rest of the people and run straight back to the mountains. It's also possible.

"Ha ha, how about Dugu Mingfu? Are you satisfied with the power of thunderbolt and thunder?"

Li Qieyou pretended to force Dugu Feng to smile, waiting for the Jiulong County Magistrate to worship and respect him.

But his words were the eyes of the blind.

Dugu Feng rubbed his ears as hard as he could, and then said, "Sir, what are you talking about? I can't hear you!"

Li forgot to worry silently turned his eyes, Ma egg. Just now he forgot to tell them to cover their ears.

Obviously, there was only tinnitus in everyone's ears. What he said was in vain.

After waiting for a long time, when everyone's ears were almost recovered, Li forgot to worry and motioned Dugu Feng to see the effect of the explosion with himself.

However, Li forgot to worry, but he always felt that he seemed to have forgotten something. Looking around, he patted his forehead and forgot the "warrior" who lit the fuse before!

Looking back to find the man, I finally saw that the Yamen servant was struggling to get up from the ground, but he seemed to be hurt. His face seemed to be cut by flying stones, and blood had flowed down.

Li forgets worry and quickly asks Niu Wu and the Zhang brothers to see if the Yamen is seriously hurt.

When the black explosive bag exploded, the shock wave was not very strong, but the gravel mixed in by Li forgetful was deadly.

Fortunately, the yamen runner ran fast. The stones splashed out at a distance of 50 or 60 steps were no longer lethal. He just cut his skin and looked at the blood. In fact, it was just a skin injury.

After confirming that the Yamen was not hurt, Li forgetful worry and Dugu Feng encouraged him and ordered him to see a doctor, all the people continued to check the effect of the explosion.

The post originally hung with the explosive bag had long disappeared at this time, but the ground of the drill ground, which was rammed very hard, had blown out a crater about one meter in diameter and half a meter deep.

As for those poor second martial brothers a few meters away from the explosion point, it goes without saying that they have all fallen to the ground, bleeding their mouths and noses, and even the pigs have been opened many holes by splashing stones. Blood is flowing out. It looks so pathetic

"Tut Tut, pity these pigs." Li forgot to worry and said hypocritically, then turned to Dugu Feng: "Dugu Mingfu, let people kill these pigs. Today, we have a fierce battle with the staff. Let's use these pork to reward the government soldiers and yamen servants."

"Ah? Oh, yes, yes, I'll order someone to do it right away." Dugu Feng looked at the pigs who had died miserably, and was already shocked and lost his soul. After listening to Li forgetful talk to him, he came back to his soul.

"Grandpa, this, this thunderbolt shocked the sky. What are the saltpeter, sulfur and charcoal you asked me to collect? This is terrible! I'm afraid that grandpa didn't use some immortal family magic?"

Li forget you will not tell Dugu Feng the truth. Gunpowder is the top secret of this era.

Even if some monks, Taoists and alchemists know about gunpowder, no one really knows the correct formula of gunpowder so far.

The composition ratio of sulfur, saltpeter and charcoal is different, which determines the explosive power of black powder.

In history, it was not until the 13th century and the Southern Song Dynasty that black gunpowder was widely used in the battlefield and became something that could kill people.

Now Zhenguan is only four years old, 630 A.D., and there is still a full five or six hundred years before gunpowder is put into the battlefield in history.

Li forgot to worry, pretending to be mysterious, nodded to Dugu Feng and forced him to spit out two words: "ran Ye!"

Worried about Dugu Feng's misunderstanding, he added: "of course, it mainly depends on the sulfur and charcoal collected by Dugu Mingfu from the city. Otherwise, I am also a skillful woman. I can't cook without rice, but I can't make this thunderbolt."

Dugu Feng was a little stunned. He didn't even have time to say hello to Li forget you. He turned around and ran out with his official clothes.

Li forgetful worry was stunned by his reaction and shouted: "Dugu Mingfu, what are you doing in a hurry?"

"I'm going to urge the people to continue scraping nitrate soil in the city!"

Dugu Feng left a word and ran away, which made Li forget you and Niu Wu stunned, and then laughed
