What is a "dust explosion"? How does it work?

Dust explosion is an extremely dangerous and lethal explosion, which refers to the dust within the explosion limit, encountering a heat source (open flame or high temperature), the flame instantly spreads in the entire mixed dust space, the chemical reaction speed is extremely fast, and a large amount of heat is released at the same time, forming a very high temperature and great pressure, which has a strong destructive force.

Under normal circumstances, if it is in such an environment, there is basically death and no life.

The principle of dust explosion, as long as the air is filled with flour, a little open flame can cause an explosion. The reason why Yan Jin knew this thing was because in the TV series "The Pretender", the boss of the Ming family sprinkled a bag of flour and used a lighter to directly blow up the entire flour mill, which shows how powerful the explosion is.

As professional ninjas, the Wakoku people naturally knew about Hibiscus's actions, and they only realized before they died that this woman was going to die with them!!

Not to mention the waste of so much flour, and this woman has to commit suicide with them, should the women of Huaxia Kingdom be so stupid?

"Slut, with you for the funeral, we have earned at least one life!" The Japanese ninja tried to take off his shoes and escape from the glue, but Hibiscus ignited faster, giving them no time to break free, which was a deathly consequence.

After shouting these words, the lighter had already ignited the flour in the air, and then they saw in their amazement that the woman of Huaxia Kingdom had completely disappeared in front of their eyes after throwing out the lighter.

They don't even understand how such a big living person could disappear!

The most painful thing in the world is that you know you are going to die, but you can't escape, and you are still standing alive and being engulfed by the fire that is coming in front of you.

The Japanese ninja instantly turned into a fireball in the explosion, and the miserable and terrible screams did not last long, and soon there were seven or eight more black corpses on the ground, emitting a strong smell of burnt meat.

At this point, this is a small detachment of the Wa Kingdom, and it has been completely wiped out by Yan Jin.

"Sister!" When Yan Jun came back with the seventh-order zombie flying a kite, he saw that it was a mess, and there were still a lot of ashes from the burning sparks around him, and those corpses were no longer distinguishable at all.

Yan Jun's whole face changed, "Sister! ”

He couldn't believe it, did Yan Jin really die with the other party? Is there really no way for my sister to escape at the moment of the explosion? For a moment, Yan Jun felt that his whole life was dark!

The seventh-order zombies were still chasing him, but Yan Jun began to slowly fall from the sky because of exhaustion, and just when he was about to be caught by the seventh-order zombies, a powerful energy fluctuation instantly permeated the surroundings.

"The system has successfully controlled the corpse, please name the new zombie!" The voice of the system Jun sounded in Yan Jin's mind, and it was finally successful once, which made Yan Jin's heart finally relax.

She raised her hand lightly and put the brand-new seventh-order zombie "Second Goods" into her space, and then saw Yan Jun crying with tears on her face, and rushed over to her, "Sister! ”

"Silly boy, if my sister dies, your team space will also disappear, you can rest assured, my sister will never leave you to die." Yan Jun was also distressed, since the end of the world, this is the first time Yan Jun has cried so much, "Sister still has to live to see our Xiao Jun marry a wife and have children, and ascend to the throne of the Ice Dragon Dragon King!" ”

"You're scared me to death!" Yan Jun's tears were like bursting the embankment, and he couldn't stop crying, "I can't do this next time, I am the face of the old Yan family, and I will be asked to do such a dangerous thing in the future!" ”

Yan Jin nodded, but he knew very well in his heart that even if he died, he would not let the young Xiaojun do such a dangerous thing, after all, this is his own brother who he brought up since he was a child, even if he is not related by blood, he is also a younger brother.

That family affection will not be reduced because of the loss of blood relationship.

Yan Jun's emotions took ten minutes to ease down, especially when he saw that Yan Jin's sleeves were scorched by the fire, and her two arms were red, he knew that she was still injured to some extent, so he quickly healed Yan Jin's injuries and helped her remove the burning pain, "Sister, don't be afraid, I will protect you, I guarantee that there will never be any scars on your arms." ”

Yan Jin nodded, and touched Yan Jun's little head with satisfaction, "With Master Yan Jun from the Jingbei base personally treating, I don't dare to leave a scar even if I want to!" ”

"Sister, this matter is very serious, you can't finish laughing." Yan Jun's little friend darkened his face and glared at his sister, "You are my sister, you are the best in everything, I can't let you be hurt." ”

"Okay, listen to our little Jun, my sister must be beautiful." Yan Jun smiled, but behind the smile, she was distressed, because she knew that Yan Jun's face was ugly, and the spiritual power contained in his body was almost bottoming out, and he was trying to heal her.

After all, he had been flying in the sky for so long, flying a kite on a seventh-order zombie, and converting the water energy into a wood ability to use, it was indeed very hard, "Little brother, I don't hurt anymore, let's go find Xiao Jing and An An!" ”

Yan Jinzheng was talking, and suddenly heard an alarm from the system Jun, "7 meters on the right, find Wei An'an, life index 3%!" ”

An An has an accident!

"Sister!" Yan Jun also seemed to feel something, "An An! ”

The siblings looked in the same direction almost at the same time, and saw a small figure stumbling towards this side not far away, and the voice was slowly filled with fear and crying, "Sister! Help me! Sister, save An An! ”

"An An!" Yan Jin's eyes suddenly turned red, she saw An An less than three hundred meters away from her, and finally couldn't hold on, and slowly fell, a few hundred meters behind her, a group of people were rushing towards An An.

"Bastard!" Yan Jun rushed out for the first time, ignoring that his spiritual power was already at the end of a strong crossbow, and roared angrily, "Don't touch my sister!" ”

"An An!" Yan Jin rushed out with it, used the greatest strength of his life, and rushed over the road!

Wei An'an fell into a warm embrace, raised her head, and saw that in her blurred vision, her brother Yanjun was calling out to herself anxiously, "An An! Ann! ”

"Brother, save Xiao Jing, Xiao Jing ......" Wei Anan wanted to raise his finger in one direction, but fell heavily into Yan Jun's arms.

Yan Jin arrived randomly, and without saying a word, he raised his hand to see a military grenade, and threw it directly at the group of people.
