My Daming New Empire

Lan Yan asked, "Where is the California Valley?"

Zhu Zhanji said with a smile: "From the northern part of Los Angeles to the northern part of Sacramento, the length is about [-] kilometers and the width is about [-] kilometers. Including San Francisco, it occupies the best location in California. Where is the United States?" The largest agricultural base in the west, the wine producing area, and many gold mines and scenic spots like Yosemite, are almost the fertile land in California except for the desert.”

"I want to go after everything I said..." Lan Yan became sentimental. "In my previous life, my dad took me on a trip. That time I went to the Grand Canyon and Yellowstone Park."

"If there is a chance, the steamship has been invented, and it will not be difficult to go out in the future."

At this time, Li Liang had already arranged for people to bury the explosives, and the servant Hu Liang who had been confessed by Lan Yan had been watching their movements, and finally came to report to Lan Yan that everything was ready.

Lan Yan nodded, and said: "Everyone, don't stand up straight. Hiding behind the wall may be a bit powerful."

But there were only two small jars of dynamite, and only one jar was ignited at a time, so no one really cared.

Others don't care, and Zhu Zhanji, as a grandson, naturally can't hide.But he also has a solution.

Someone moved two chairs, and he sat down with Lan Yan, and there was a row of people in front of him.

Li Liang personally ignited the fuse of the first pot of explosives, then quickly ran out, lying on the wall and waiting for the explosion.

The same goes for the others, looking at the venue with concern, wanting to see how powerful this explosive is.

The first jar of nitrocellulose explosives that was ignited was actually much less powerful than picric acid, but when five catties of explosives were detonated, the sky was filled with mud like rain.

Zhu Zhanji and Lan Yan had been prepared for a long time. They blocked their ears and opened their mouths slightly, so they were not greatly affected at all.

Many people were completely frightened, and many fell to the ground due to the impact, screaming desperately, because their eardrums were so shocked that they couldn't hear, so they couldn't hear their own voices at all.

Li Liang was still fine. Because he was lying on the wall, he fell on his back after the loud noise, and the impact was not great. Many people standing there had blood from their ears.

The two looked at each other, and both laughed with a wicked sense of humor.

Li Liang came to his senses at this moment, got up in a dazed state, took two stumbling steps, and then fell down again.

Afterwards, he ran over rolling and crawling, howling as he ran. "Your Highness, this servant thought that I would never be able to serve you again!"

Chapter 79

Because of his deafness, he howled so loudly that Zhu Zhanji couldn't help laughing.

But when he hugged Zhu Zhanji's leg with snot and tears, Zhu Zhanji was disgusted again.

He kicked him away lightly. "Howling, what are you doing, aren't you okay!"

He touched his body now, and it seemed that there were no missing parts, and he started crying and laughing again. "The maidservant just thought that she could no longer serve His Highness."

"Okay, okay, let's see if other people are okay. If there is nothing, go and see how it works."

He was not afraid just now, but now he is a little scared. "It's better to order the other one, let's see it again..."

There is also a big killer in there, and he is scared now.

Not only was he scared, but most of the researchers were also scared at this moment.Only a few gunpowder experts rushed forward as if they had found a treasure, observing the big crater that was blown out.

A pot of explosives weighing about five catties blasted the soil into a large pit with a diameter of about three meters, and all the mounds above the surface were swept away by the shock wave.

Several gunpowder experts busily began to measure, and calculated the power of gunpowder based on the big pit on the scene.

Seeing this big hole, no one doubts that the new type of gunpowder, no, the power of what should be called explosives is far more powerful than granular black powder.

The power of black powder needs more gravel and steel balls to increase.Because black powder is not a real explosive in terms of detonation speed, detonation volume, and detonation pressure, except for its explosive heat.

In ancient battles for cities, a city gate could not be blown open with dozens of catties of black powder. Although the black powder was impure, it was already known how powerful it was.

As for nitrocellulose explosives, although their power is not as powerful as TNT explosives, let alone the more powerful picric acid explosives, they have evolved from gunpowder to explosives.

Not only the researchers of the Chemical Research Institute were alarmed, but several nearby research institutes, including Habayashi Wei who was on duty, were actually quite frightened.

In previous experiments with gunpowder, when it was so powerful, the house almost collapsed.

But seeing Zhu Zhanji standing there properly, everyone was relieved, and returned to their duty posts, stopping more and more onlookers outside.

After being busy for a full quarter of an hour, the researchers calculated the power of the gunpowder based on the damage to the big crater and the damage to the wooden pillars inserted in the ground to test the power.

The power of this new type of gunpowder is more than five times that of granulated black gunpowder. This calculation result is not much different from what Lan Yan knows.

Seeing those researchers calculating non-stop, Lan Yan said softly: "Black powder: the detonation velocity is about 500 m/s, the volume of detonation gas is 280 liters/kg, and the detonation heat is 3015 kJ/kg. And the detonation velocity of TNT explosive is 6920 m/s seconds, the volume of detonation gas is 620 liters/kg, and the detonation heat is 5066 kJ/kg. The detonation velocity of picric acid is 8000 m/s, and the detonation heat is 6322 kJ/kg.

Detonation velocity is the most important factor to measure the power of an instant explosion. In simple comparison, the explosive power of TNT is 14 times that of black powder, and nitroglycerin is 16 times that of black powder. One ton of explosive is equivalent to six or seven tons of high-purity black powder. And there must be a detonator that ignites and explodes instantly, detonating all the black powder at the same time! "

Zhu Zhanji nodded and said, "Don't publish these data for the time being, and you will show them to shock them later. Your nitrocellulose explosive should belong to the nitroglycerin explosive series. Why is it so much less powerful?"

Lan Yan said dissatisfiedly: "Then there must be materials with higher purity..."

Zhu Zhanji also knew that he had gone too far. The horse hadn't been fed yet, as if it was running away.

He pinched Lan Yan's small face, and said with a smile: "I was wrong, and I will make it up to you tonight."

When all the civil and military officials saw Zhu Zhanji's movements, they were all taken aback. They quickly turned their backs, or lowered their heads, pretending not to see his movements.

After recording the experimental data, Li Liang had regained his composure at this moment, bowed to Lan Yan, and asked, "Di Liang, is the other can of explosives as powerful as this?"

Lan Yan nodded and said: "Really, it should be more powerful, so you have to be careful."

"Xie Liangdi cares."

Li Liang was scared out of his wits just now, but now he is still scared, but feels extremely honored.Anyway, he won't give up this opportunity to light the fire himself. At worst, he will lie on the ground when he runs out later, so as not to be knocked down directly.

And other officials knelt down in front of Zhu Zhanji, begging him to sit farther away, so as not to be affected.

Of course Zhu Zhanji would not refuse, the eardrums ached as the distance got closer.What's more, he and Lan Yan covered their ears and opened their mouths in an ugly posture, which put the guards in danger.

Several servants quickly moved the chairs to the corridor at least 100 meters away. Zhu Zhanji stopped sitting at all, and stood by a pillar, waiting for Li Dian to light the fire.

The other researchers also had experience this time, and they dared not underestimate the power of the new explosives. Although they were not as far away as Zhu Zhanji, they all squatted down, not daring to face the impact of the explosives directly.

Li Liang ignited another explosive in the venue, then turned and ran.

Maybe he wanted to show his merits in front of Zhu Zhanji. After he ran out of the test field, he didn't stop and squat down. Instead, he continued to walk quickly towards Zhu Zhanji.

Then, there was a louder noise than before, a large amount of dust exploded, and the huge shock wave caused him to be knocked down to the ground.

Frightened, several young eunuchs ran towards him and helped him up.

He was thrown so badly that his nose bleed because he hit the ground.

Seeing Zhu Zhanji who couldn't help laughing and Lan Yan who couldn't stop laughing, he felt that he was really unlucky, so he turned around and ran away covering his face. "Take our family to wash your face..."

Seeing the scale of the explosion, Yi Qingzi was so shocked that he had nothing to say.He looked at Lan Yan, who was hiding behind Zhu Zhanji, smiling like a girl, but he seemed to see a devil.
