As soon as the cold winter was gone, Wei Yan and Zhao Yun each led their troops and set off.

On the one hand, Zhuge Liang arranged for sentry spies to closely monitor the movements of Xudu, and on the other hand, he mobilized all the logistics forces in Jingzhou to supply the troops advancing westward on both routes.

Hua Wenxuan sits in Xiangyang, studying utensils with He Yan, Huang Yueying and others every day to explore the mysteries of the black stone.

After being squeezed out of power countless times, Hua Wenxuan has never been able to figure out the connection between the black stone and the thunder and lightning, and he has never understood why the black stone can absorb his magic skills, and it seems that not all secrets can be revealed through trial and error.

However, according to the formula that Hua Wenxuan didn't remember very clearly, Huang Yueying actually made up black powder, which really scared Hua Wenxuan.

When Huang Yueying ran over with a black and gray face, Hua Wenxuan instantly remembered how she looked when she first saw her, so eccentric.

Huang Yueying was holding a bunch of black particles in her hand, and suddenly broke into the study from the backyard, startling Hua Wenxuan, who was frolicking with He Yan, "Look, look, that's the ratio!" It's going to burn fast! ”

He Yan panicked, and hurriedly called someone to fetch water, Huang Yueying called Hua Wenxuan forward, Hua Wenxuan looked confused, and secretly complained, I just roughly remember those three things, why did this girl really get things out?

Hua Wenxuan looked at the black powder in Huang Yueying's hand, and smacked Huang Yueying's face distressedly, "It doesn't matter if you don't make black powder, what if you hurt you?" Besides, although the black powder is available now, the actual effect is not great, unless it is to bury more points when the city wall is blown up, it is still a big problem to keep it on weekdays, and it cannot be damp or fired! ”

"Let's do it first! Didn't you say that this gunpowder is the foundation of firearms, and with this, we can develop weapons that are more powerful than repeaters! Huang Yueying rubbed her nose.

Hua Wenxuan nodded, "But the current iron-making process is not good!" It's going to blow up! ”

"Explode?"

"Yes!" Hua Wenxuan frowned and thought about it, how to explain it?

Hua Wenxuan took the paper and ink, drew the appearance of a cannon breech, pointed to the gun body and said: "If the material of this gun body is not good, the gunpowder will explode in the back, and it should be blocked by the environment, and the impact force will be released in the direction of the gun mouth. ”

Huang Yueying pursed her lips, "Then what's the use of us getting this gunpowder out?" ”

Hua Wenxuan opened his mouth wide and was stunned for a moment, this was originally a casual remark, how could he have expected Huang Yueying to actually do this!

Hua Wenxuan rubbed his head, lightning, thunder, thunder, thunderbolt? Thunderstorm beads?

Hua Wenxuan touched his head, looked at the black powder in Huang Yueying's hand, took a little and rubbed it in his hand, but it was a spark, and Hua Wenxuan's fingers burned a bubble.

Huang Yueying hurriedly came over to see, "You idiot! What did you do? ”

Although Hua Wenxuan's hand hurt badly, there was a smile on his face, "This thing may have another useful use!" ”

Hua Wenxuan turned around and took a piece of paper, wrapped it in a little black powder, tied it with silk thread, and put it far away outside the door.

Then, Hua Wenxuan thought back to the feeling when he was running wild outside Yingchuan City in the past, transported the electricity of his whole body, gathered it between his fingers, and shook his hand at the real place, and a beam of electricity shot straight through, and the package of black powder in the middle of it, with a "snap", suddenly burst into flames, although it was a matter of an instant, but it stained all the bricks black.

Hua Wenxuan licked his lips, just a small packet, it can be like this, if the amount is large, then replace the container, and then put a sharp weapon on the inner wall of the container, once it is ignited, isn't it as unavoidable as a rainstorm pear flower needle?

Hua Wenxuan returned to the bookcase, took the pen and ink, drew a sphere on the paper, two layers inside and outside, the inner layer was filled with gunpowder, and the outer layer was filled with thistle, leaving a hole to lead directly to the inner layer, and handed it to Huang Yueying, "Can such a spherical iron tool be made at the moment?" ”

Huang Yueying picked up the drawings, looked at them for a moment, and pondered for a moment in her heart, "It's not a big problem, but what does Wenxuan want this thing for?" ”

"Yueying doesn't know how powerful this thing is, I'll tell you how good it is after I make it!" Hua Wenxuan smiled slightly, "In addition, mix a little black powder with cotton thread and seal it with wax, and I will use it as a lead!" ”

Although Huang Yueying didn't know what Hua Wenxuan was going to do, she still complied.

Three days later, Huang Yueying asked for a craftsman to make the objects that Hua Wenxuan wanted, and made a batch of black powder, Hua Wenxuan took Huang Yueying and He Yan to a secluded place outside the city, carefully poured the black powder into the sphere, and inserted the lead made of cotton thread.

"You two go farther away, wait for me after you get to the hillside over there!" Hua Wenxuan pointed to the hillside in the distance and said.

He Yan didn't know why this was the case, but Huang Yueying knew the ability of black powder, she watched Hua Wenxuan pour in nearly a pound of black powder, wouldn't it be very dangerous to burst into flames.

After Huang Yueying pulled He Yan to the hillside, she looked forward to it.

Hua Wenxuan breathed a deep sigh, after all, this lead and black powder are things that appeared hundreds of years in advance, and if they don't play well, this life will be over.

Hua Wenxuan carefully lit the torch, ignited the lead, and ran to the back of the hillside as if flying, and the three of them waited anxiously behind the hillside, poking their heads to look at the lead that was emitting wisps of green smoke.

Slowly, the outer end of the lead had burned out, and green smoke slowly drifted out along the hole.

He Yan raised his head slightly, "What is this for?" The ball didn't react! ”

"Wait and see!" Hua Wenxuan looked at it, and was about to speak, there was a loud bang, Hua Wenxuan hurriedly reached out and pressed He Yan's head, and after a long time, the three of them looked up, only to see that the place where the iron ball was originally placed was already scorched black, and the iron ball had been blown up and flew far away, and on the surrounding tree trunks, countless iron thistles were deeply embedded in the tree trunks, and the trunks closest to the iron balls were obviously marked by the iron thistles countless openings.

Huang Yueying and He Yan were shocked by the scene in front of them, Huang Yueying never expected that the power of this black powder was so great, although Hua Wenxuan knew that fireworks were nothing more than that, but the thought of being able to make a bomb in the Three Kingdoms era was also beautiful.

"Yueying, organize a group of bold and careful craftsmen, set up a firearms bureau, sign a life and death contract, no one is allowed to let go, specialize in this thing, the volume is a little smaller, you can throw it with one palm, the lead can be like this, the exposed section is sealed with wax, pay attention to moisture-proof arson, find a secluded place to store, it will definitely come in handy in the future!" Hua Wenxuan commanded.

Huang Yueying nodded, since Hua Wenxuan's magic was restrained by Heishi, if this thing was completed, Hua Wenxuan would not have to worry, after all, according to this power, no military formation could not carry it.
