"Protect the lord! Where did the Kunlun slave come from! Over there, Guan Hai and Zhou Cang quickly pulled out their swords and protected Liu Mang behind them. Because the person on the other side is so scary, it is pitch black, revealing only two eyes and the yellow teeth of the mouthful.

"Take it for me!" Guan Hai shouted to his guards.

"Yes," a group of guards pressed towards the black man.

"Lord, it's me, it's me!" The black-covered man over there was gesturing loudly in defense.

"Wait!" Liu Mang looked at the man over there who looked like an African, and his voice was a little familiar.

"Ziyang? Is that you? Xu Shu on the side asked a little puzzled.

"It's me, it's me, military advisor, no, internal minister, I'm Liu Ye and Liu Ziyang!" The African man said to Liu Mang and the others.

"Are you Liu Ye? Don't laugh, although my brother Liu is not a beautiful man, but he is also beautiful, you are such a black and ugly person who looks uglier than my eldest brother and dares to pretend to be my Liu brother. Zhou Cang's big mouth opened again, Guan Hai raised his eyebrows, what is called uglier than him Guan Hai, what's wrong with ugliness, don't wait to see people. Fortunately, Guan Hai always knew that Zhou Cang's mouth was broken, otherwise Zhou Cang would have to feel good.

"I'm really Liu Ye, Zhou Cang, you guy, you went up and ate the turtle that I have raised for more than ten years, I haven't looked for you yet!" Liu Ye yelled at Zhou Cang over there, last time Zhou Cang went to Zhou Cang's house on Liu Mang's order, it was Liu Mang who asked Liu Ye to come to reminisce about the past, but he didn't expect Zhou Cang to go, but he conveniently hid a pet turtle raised by Liu Ye in his sleeve and brought it back, if it wasn't for the chef in the mansion who served the wrong dish. Liu Ye couldn't find out that his turtle had been poisoned by Zhou Cang. It became turtle soup.

"Yikes! How do you know! Zhou Cang jumped up like a cat that had been stepped on by its tail.

"Humph! ~" Liu Ye snorted coldly: "Zhou Cang, if you don't give face to the lord, I'll find you." Today, you still think I'm ugly. Liu Ye pointed at Zhou Cang and scolded him.

"It's really Ziyang!" Liu Mang looked at Zhou Cang's evasive eyes over there, and immediately knew that it was really Liu Ye.

"Brother Liu, how could you do this!" Zhou Cang could only play haha, there was originally a Guan Hai to help him talk, who let offend two people at once, Guan Hai stood aside and couldn't see Zhou Cang being scolded, so Zhou Cang could only speak cheekily.

"Humph!" Liu Ye wiped his face with his clothes, he wanted to wipe the ashes off his face, but he didn't want to think that his clothes were already the same as others. So it got darker and darker, and the guy who was in Zhou Cang immediately grinned.

Liu Ye was about to stare at him, but then he thought of something, ran to Zhou Cang, and pressed his face directly towards Zhou Cang.

"Brother Liu, Brother Liu, what are you going to do, what are you going to do, don't, don't!" Zhou Cang yelled.

Liu Mang looked at the two people in front of him with a black line. Liu Ye's true face was finally revealed, because he was near Shouchun, so Zhou Cang was wearing ordinary light armor. Liu Ye used the clothes on Zhou Cang's body to wipe all the black ash on his face, which made Liu Mang really recognize it.

"Brother Liu, you have a new dress for me!" Over there, Zhou Cang shouted.

"Alright, that's enough!" Liu Mang knew that if he didn't stop it, the two of them would be endless.

"Ziyang, what's going on here!" Liu Mang asked Liu Ye, he came happily, although seeing the tragic situation here made Liu Mang a little frightened, but it intensified his kind of confirmation.

"Lord, it's nothing! I made that thing called gunpowder! Liu Ye said indifferently to Liu Mang.

"Gunpowder? Did you make it? Liu Mang's eyes widened and asked Liu Ye.

"yes!" Liu Ye explained to Liu Mang, "Lord, please look, this is gunpowder." Saying that, Liu Ye took out something from the hands of his subordinates behind him and taught it to Liu Mang.

"Black-brown!" Liu Mang took it, which was already very similar to the black powder in his memory.

Everyone thinks that gunpowder is very simple, isn't it saltpeter charcoal and sulfur, but you must know that if you get these three things in a normal way, the gunpowder made can be used as a small firework at most, and if you don't use a fixed ratio, the fireworks may not be released!

The gunpowder that Liu Mang needs Liu Ye to make is just ordinary black powder, but there are still a lot of ways in it, what is gunpowder used for, Liu Mang will never use him to set off fireworks to play, although this is a thing that can please the tigress at home, but Liu Mang wants to gain the upper hand in this troubled world, in other words, he wants to use it in the military

Gunpowder is the energy source for a weapon to launch a projectile, which can be divided into ignition powder, propellant, and solid propellant according to its use. Among them, propellants are divided into: gun propellant and cannon propellant.

The role of various ingredients is different, so even if there is a process, Liu Mang, a liberal arts student, still needs to turn to Liu Ye, an inventor in the late Han Dynasty.

"This is gunpowder? It's nothing! It's like dirt! Zhou Cang spoke again, and as soon as he opened his mouth, he naturally offended people.

"You know what, this gunpowder is our family." Liu Ye's deputy on the side immediately opened his mouth to refute.

was stopped by Liu Ye and retreated.

"Zhou Cang, don't underestimate this black soil-like thing, just these black soil. He's going to make this place like this! Liu Mang pointed to the place where the smell of gunpowder was still emanating.

"Is it these black dirt that made this place like this? Haha, lord, you are so funny, you know that you deceived me Zhou Cang, this is obviously God's thunder! "Zhou Cang looks like you're lying to me.

"Liared to you? Hehe, there is still a barrel of gunpowder over there in Zhoucang, do you want to sit on it and take a look! Did I light it for you? Liu Mang smiled and said to Zhou Cang, looking at Liu Mang's smile, Zhou Cang was already familiar with it, that is the prelude to someone's bad luck, and immediately Zhou Cang shook his head violently, "I believe, I believe!" Zhou Cang looked around again, the fire had not been extinguished, there were still people in charge of the wounded, and there were many corpses of the dead.

"Lord, do you know everything?" Liu Ye said to Liu Mang with a wry smile.

"Of course I do!" Liu Mang replied to Liu Ye, what kind of thunder came, Liu Mang didn't believe it, although the thunder may bring casualties, but it is not so terrifying, this is a row of houses have been overturned and lit, although Liu Mang has not really seen the explosion, but I have always seen it in TV and movies, although it is a special effect, but the reality is much stronger than the special effects.

"Didn't I let you show me once you made it!" Liu Mang blamed Liu Ye a little.

"Lord, this, this, no, it's not Lord Liu Ye's fault, yes, it's my fault!" Behind Liu Ye, a young man stood up and said to Liu Mang.

"Huh?" Liu Mang thought that this person was nervous, so he couldn't speak clearly, but then he heard that it was obvious that it was not this reason why the person was born with a stutter.

"Lord, this qiē is because Ye failed to listen to the lord's order, and it has nothing to do with Ma Shilang! If you want to punish me, punish me" Liu Ye also knelt down.

"Huh?" Liu Mang didn't know who this young man was, so he asked Liu Ye to intercede for him. "Ma Shilang?" This is the second-in-command of the Ministry of Industry, this is this young man! (To be continued......)
